Adalimumab, sold under the brand name Humira, enjoyed a long run as one of the world’s best-selling medicines. But its 20-year, competition-free period has ended, and despite its best efforts to delay their arrival, drug manufacturer AbbVie now faces increasing competition from biosimilars entering the marketplace.
 

But one biosimilar about to be launched may be something of a game changer. Coherus BioSciences has announced plans to market its biosimilar Yusimry (adalimumab-aqvh) at a cost of $995 for two autoinjectors. This represents an approximate 85% discount over Humira’s sale list price of $6922.

This price, however, is slated to plunge even further as Coherus has also revealed that it will work with the Mark Cuban Cost Plus Drug Company (MCCPDC) to offer an even lower price. When Yusimry launches in July, it will sell for about $579 for two autoinjectors, making it the lowest-priced adalimumab biosimilar on the market.

“Coherus and Cost Plus Drug Company share a common mission, to increase access to high-quality medicine for patients at an affordable price,” said Dennis Lanfear, MBA, president, CEO and chairman of Coherus. “Mark Cuban and his team offer innovative solutions to health care problems, and Coherus is also a highly innovative company focused on unmet patient needs.”

He noted that, with adalimumab biosimilar pricing, this translates to a low list price approach. “We are pleased that Yusimry will be a part of that, as the first biologic they carry,” Mr. Lanfear said.

MCCPDC prices are based on the cost of ingredients and manufacturing plus 15% margin, a $3 pharmacy dispensing fee, and a $5 shipping fee. The company has expanded its inventory from 100 generics to more than 350 medications since it launched in January 2022. While MCCPDC is primarily directed to people who are paying cash for drugs, it does take insurance from select plans. And even for people who are covered by other insurers, the cost of drugs from Mr. Cuban’s company may be less than their out-of-pocket costs if they did go through their payer.

The low pricing of Yusimry is welcome, said Marcus Snow, MD, an assistant professor in the division of rheumatology at the University of Nebraska Medical Center, Omaha, but he pointed out that it is still a very expensive drug. “For patients who can’t afford Humira due to poor insurance coverage and high out-of-pocket costs, it is a welcome option. But it’s also unclear how many patients who lack adequate health insurance coverage can afford to pay $579 a month out of their own pockets.”
 

The biosimilars are coming

By early December 2022, the Food and Drug Administration had approved seven Humira biosimilars, and Amgen launched the first biosimilar to come on the market, Amjevita, soon afterward. By July 2023, half a dozen more are expected to enter the marketplace, said Steven Horvitz, managing director of EMC Analytics Group, a pharmaceutical research firm.

Mr. Horvitz agrees that the system is out of control, but it is unclear how much of an effect the low price tag on the Coherus product will have. “Some insurers may say, ‘we want the lowest price, and we don’t care about rebates,’ and will go with it,” he said. “PBMs [pharmacy benefit managers] are all about economics, so we have to see how many of their major clients will ask for the lowest price.”

Amgen has more or less followed the status quo on pricing for its biosimilar, but with a twist. It›s being offered at two different prices: $85,494 a year, which is only a 5% discount from Humira’s list price, or at $40,497 a year, a 55% discount. However, to date, the lower price has generally not been granted favorable formulary placement by PBMs. The plans that adopt the higher-priced biosimilar will get bigger rebates, but patients with coinsurance and deductibles will pay more out of pocket.

It is yet unknown how the pricing on Yusimry will affect the biosimilars ready to launch. “Will it give them pause for thought or not make any difference?” Mr. Horvitz said. “The companies do not reveal their pricing before the fact, so we have to wait and see.”

Large PBMs have not jumped at the opportunity to offer the Coherus biosimilar, but SmithRx, which bills itself as “next-generation pharmacy benefits management,” announced that it will offer Yusimry to its members at a discount of more than 90%.

“Unlike traditional PBMs, SmithRx prioritizes transparency and up-front cost savings. Humira is often an employer’s top drug expense so offering a low-cost alternative will have significant impact,” Jake Frenz, CEO and founder of SmithRx, said in a statement. “We’re excited to work with Cost Plus Drugs to bring this biosimilar to our members – and significantly reduce costs for them and their employers.”

Emilee Gibson, MD, recently graduated from Southern Illinois University, Springfield, and starts her ob.gyn. residency at Vanderbilt University Medical Center in Nashville, Tenn., later this month. Abortion is permitted in Illinois but banned in Tennessee, a factor she weighed cautiously when she applied for residencies.

Dr. Gibson told this news organization that medical students, not just those interested in ob.gyn., are starting to think more about what it means to move to a state where it might be difficult to access abortion care. “Just from a personal standpoint, that’s a little scary.”

The Supreme Court’s decision to overturn Roe v. Wade abortion rights last June threatened to derail ob.gyns. in training from pursuing the specialty or locating in states that have banned or limited abortion.

Early signals from the Dobbs v. Jackson decision suggest a potential decline in ob.gyn. residents choosing abortion-restrictive states, but some industry leaders, residents, and medical students say it may be too early to judge the full impact of the ruling because most students were already far along in their decision and application for a 2023 residency position.

At this point, some ob.gyn. students are planning careers on the basis of whether they have family ties in a particular state, whether limiting their search might hurt their potential to match in a competitive specialty, and whether their faith in the family planning and abortion training being offered by a program outweighs the drawbacks of being in a state with abortion bans or restrictions.

Lucy Brown, MD, a recent graduate of Indiana University, Indianapolis, said in an interview that she’d be “very nervous” about living and practicing in abortion-restricted Indiana if she were ready to start a family.

Dr. Brown said that she mostly limited applications in the recent Match to ob.gyn. residencies in states that protected abortion rights. Though she applied to a program in her home state of Kentucky, she noted that it – along with a program in Missouri – was very low on her rank list because of their abortion restrictions.

Ultimately, Dr. Brown matched at Johns Hopkins University, Baltimore, where she will receive abortion training and assist with abortions throughout her residency. Maryland’s abortion rights status was a big attraction, she said. “Abortion is integrated into every aspect of the education.”
 

By the numbers

For students applying to residencies this summer, evaluating the state legislative landscape is a little clearer than it was 1 year ago but is still evolving. As of June 1, 56 ob.gyn. residency programs and more than 1,100 medical residents are in states with the most restrictive bans in the country (19% of all programs), according to the Bixby Center for Reproductive Health at the University of California, San Francisco.

In terms of the latest abortion laws: 14 states banned abortion, 2 states banned abortion between 6 and 12 weeks, and 9 states banned abortion between 15 and 22 weeks, whereas abortion is legal in 25 states and Washington, according to a recent analysis by the Kaiser Family Foundation.

The impact on residencies? The Association of American Medical Colleges recently reported a 2% drop in the number of U.S. MD seniors who applied to residencies and a 5% decline in the number of seniors who applied to ob.gyn. residencies. In states where abortion was banned, the number of senior applicants to ob.gyn. programs dropped by more than 10%, according to AAMC’s Research and Action Institute.

“U.S. MD seniors appear, in general, more likely to avoid states where abortions are banned,” said Atul Grover, MD, PhD, executive director of the Research and Action Institute. “That’s a big difference between states where there are abortion bans and gestational limits and states with no bans or limits; it’s almost twice as large,” Dr. Grover said in an interview. “The question is: Was it a 1-year blip or something that will be the beginning of a trend?”

In a statement to this news organization, officials from the American College of Obstetricians and Gynecologists and the Association of Professors of Gynecology and Obstetrics said that they were aware of the AAMC data but needed to further evaluate the impact of the Dobbs ruling.

A survey released at ACOG’s annual meeting in May found that 58% of third- and fourth-year medical students were unlikely to apply to a residency program in a state with abortion restrictions. Conducted after the Dobbs ruling last year, the survey found that future physicians are choosing where to attend residency according to state abortion policies, indicating that access to abortion care is changing the landscape of medical practice.

“For personal as well as professional reasons, reproductive health care access is now a key factor in residency match decisions as a result of Dobbs,” lead author Ariana Traub, MPH, said. She studies at Emory University, Atlanta, where abortion is restricted.

“Many students, including myself, struggle when trying to decide whether to stay in restricted states where the need is greatest (highest maternal mortality, infant mortality, lower number of physicians), versus going to an unrestricted state” for more comprehensive training and care, Ms. Traub said. “Regardless of this decision, Dobbs and subsequent abortion laws are making students question what matters most and how they can provide the best care.”

In another recently published survey, University of Miami fourth-year student Morgan Levy, MD, MPH, and colleagues found that 77% of students would prefer to apply to a residency program in a state that preserves access to abortion. Ensuring access to those services for themselves or a family member was a key factor, according to the paper published in the Journal of General Internal Medicine.

For Dr. Levy, who recently graduated from a school in abortion-restricted Florida and will soon apply to ob.gyn. residencies, the Dobbs decision made her more committed to becoming an ob.gyn., an interest she’s had since college, she said.

“I do not intend to limit my search,” Dr. Levy said in an interview. “In the states where there are restrictions in place, it’s really important to make sure that people are getting good care,” she said.
 

Differing perspective

Though survey and anecdotal data show that students and residents expressing hesitation about states with bans or restrictive laws, it appears that most who applied to residency programs during the 2023 Match did not shy away from those states. Almost all the open ob.gyn. residency positions were filled, according to the National Resident Matching Program.

There was no change in how U.S. MD seniors applying for 2023 residency ranked programs on the basis of whether abortion was legal, limited, or banned in the state where a program was based, Donna Lamb, DHSc, MBA, BSN, president and CEO of the NRMP, said.

“We’re seeing what we’ve seen over the past 5 years, and that is a very high fill rate, a very high rate of preference for ob.gyn., and not a heck of a lot of change,” Dr. Lamb said, noting that ob.gyn. programs continue to be very competitive. “We have more applicants than we have positions available,” she said.

In the most recent Match, there were 2,100 applicants (more than half U.S. MD seniors) for about 1,500 slots, with 1,499 initial matches, according to NRMP data. The overall fill rate was 99.7% after the Supplemental Offer and Assistance Program and Electronic Residency Applications process, NRMP reported. The results are similar to what NRMP reported as its previous all-time high year for ob.gyn. placements.

There was a dip in applicants from 2022 to 2023, even though the slots available stayed the same, but it was not markedly different from the previous 5 years, Dr. Lamb said.

“While the Dobbs decision may, indeed, have impacted applicant and application numbers to residency programs, interventions such as signaling may also contribute to the decrease in numbers of applications submitted as well,” AnnaMarie Connolly, MD, ACOG chief of education and academic affairs, and Arthur Ollendorff, MD, APOG president, said in a statement to this news organization.

For the first time in 2022, Match Day applicants were required to “signal” interest in a particular program in an effort to reduce the number of applications and cost to medical students, they noted.
 

Personal view

When it was time for Dr. Gibson to apply for ob.gyn. residencies, she wondered: Where do you apply in this landscape? But she did not limit her applications: “If I don’t apply to Indiana, Missouri, Tennessee, Wisconsin, Iowa, I’m taking a lot of really great programs off the table.” She did not want to hurt her chances for a match in a competitive specialty, she said.

“Being in Tennessee is going to give me a very different, unique opportunity to hopefully do a lot of advocacy and lobbying and hopefully have my voice heard in maybe a different way than [in Illinois],” Dr. Gibson added.

Cassie Crifase, MPH, a fourth-year student at the University of Wisconsin–Madison applying to ob.gyn. residencies in next year’s Match, said in an interview that she’s concerned about the health risk of living in a state with abortion restrictions. Wisconsin is one of those.

“My list skews toward programs that are in abortion-protected states, but I also am applying to some programs that are in restricted states.” Those states would have to help her meet the Accreditation Council for Graduate Medical Education training requirements. And, she said, she’d want to know if she could still advocate for abortion access in the state.

Sereena Jivraj, a third-year medical student at Texas Christian University in Fort Worth, said that she won’t apply to programs in Alabama, Mississippi, Arkansas, and other nearby states with abortion restrictions. However, Texas is still on her list. “I’m from Texas, my family lives in Texas, and I go to school in Fort Worth, so I have made those connections,” Ms. Jivraj said.

Student advisers generally encourage ob.gyn. hopefuls to apply to 60-100 programs to ensure that they will match, Ms. Jivraj said. “How are you supposed to apply to 100 programs if many of them fall within states with high restrictions?”
 

What the future holds

Ms. Jivraj said that she’s concerned about what the future holds, especially if the law does not change in Texas. “I don’t want to go to work every day wondering if I’m going to go to jail for something that I say,” she said.

Dr. Crifase has similar fears. “I want to be able to provide the best care for my patients and that would require being able to do those procedures without having to have my first thought be: Is this legal?”

“Things feel very volatile and uncertain,” Pamela Merritt, executive director of the nonprofit Medical Students for Choice in Philadelphia, where abortion is permitted, said. “What we’re asking medical students to do right now is to envision a future in a profession, a lifetime of providing care, where the policies and procedures and standards of the profession are under attack by 26 state legislatures and the federal court system,” she said.

“I don’t think you’re going to see people as willing to take risk.” She added that if someone matches to a program and then has regrets, “You can’t easily jump from residency program to residency program.”

Dr. Levy believes that the impact of the Dobbs decision is “definitely going to be a more common question of applicants to their potential programs.”

Applicants undoubtedly are thinking about how abortion restrictions or bans might affect their own health or that of their partners or families, she said. In a 2022 survey, Dr. Levy and colleagues reported that abortion is not uncommon among physicians, with 11.5% of the 1,566 respondents who had been pregnant saying they had at least one therapeutic abortion.

Students are also considering the potential ramification of a ban on emergency contraception and laws that criminalize physicians’ provision of abortion care, Dr. Levy said. Another complicating factor is individuals’ family ties or roots in specific geographic areas, she said.

Prospective residents will also have a lot of questions about how they will receive family planning training, Dr. Levy commented. “If you’re somewhere that you can’t really provide full-spectrum reproductive health care, then the question will become: How is the program going to provide that training?”

When it was time for Dr. Gibson to apply for ob.gyn. residencies, she wondered: Where do you apply in this landscape? But she did not limit her applications: “If I don’t apply to Indiana, Missouri, Tennessee, Wisconsin, Iowa, I’m taking a lot of really great programs off the table.” She did not want to hurt her chances for a match in a competitive specialty, she said.

“Being in Tennessee is going to give me a very different, unique opportunity to hopefully do a lot of advocacy and lobbying and hopefully have my voice heard in maybe a different way than [in Illinois],” Dr. Gibson added.

Cassie Crifase, MPH, a fourth-year student at the University of Wisconsin–Madison applying to ob.gyn. residencies in next year’s Match, said in an interview that she’s concerned about the health risk of living in a state with abortion restrictions. Wisconsin is one of those.

“My list skews toward programs that are in abortion-protected states, but I also am applying to some programs that are in restricted states.” Those states would have to help her meet the Accreditation Council for Graduate Medical Education training requirements. And, she said, she’d want to know if she could still advocate for abortion access in the state.

Sereena Jivraj, a third-year medical student at Texas Christian University in Fort Worth, said that she won’t apply to programs in Alabama, Mississippi, Arkansas, and other nearby states with abortion restrictions. However, Texas is still on her list. “I’m from Texas, my family lives in Texas, and I go to school in Fort Worth, so I have made those connections,” Ms. Jivraj said.

Student advisers generally encourage ob.gyn. hopefuls to apply to 60-100 programs to ensure that they will match, Ms. Jivraj said. “How are you supposed to apply to 100 programs if many of them fall within states with high restrictions?”
 

What the future holds

Ms. Jivraj said that she’s concerned about what the future holds, especially if the law does not change in Texas. “I don’t want to go to work every day wondering if I’m going to go to jail for something that I say,” she said.

Dr. Crifase has similar fears. “I want to be able to provide the best care for my patients and that would require being able to do those procedures without having to have my first thought be: Is this legal?”

“Things feel very volatile and uncertain,” Pamela Merritt, executive director of the nonprofit Medical Students for Choice in Philadelphia, where abortion is permitted, said. “What we’re asking medical students to do right now is to envision a future in a profession, a lifetime of providing care, where the policies and procedures and standards of the profession are under attack by 26 state legislatures and the federal court system,” she said.

“I don’t think you’re going to see people as willing to take risk.” She added that if someone matches to a program and then has regrets, “You can’t easily jump from residency program to residency program.”

Dr. Levy believes that the impact of the Dobbs decision is “definitely going to be a more common question of applicants to their potential programs.”

Applicants undoubtedly are thinking about how abortion restrictions or bans might affect their own health or that of their partners or families, she said. In a 2022 survey, Dr. Levy and colleagues reported that abortion is not uncommon among physicians, with 11.5% of the 1,566 respondents who had been pregnant saying they had at least one therapeutic abortion.

Students are also considering the potential ramification of a ban on emergency contraception and laws that criminalize physicians’ provision of abortion care, Dr. Levy said. Another complicating factor is individuals’ family ties or roots in specific geographic areas, she said.

Prospective residents will also have a lot of questions about how they will receive family planning training, Dr. Levy commented. “If you’re somewhere that you can’t really provide full-spectrum reproductive health care, then the question will become: How is the program going to provide that training?”

Emilee Gibson, MD, recently graduated from Southern Illinois University, Springfield, and starts her ob.gyn. residency at Vanderbilt University Medical Center in Nashville, Tenn., later this month. Abortion is permitted in Illinois but banned in Tennessee, a factor she weighed cautiously when she applied for residencies.

Dr. Gibson told this news organization that medical students, not just those interested in ob.gyn., are starting to think more about what it means to move to a state where it might be difficult to access abortion care. “Just from a personal standpoint, that’s a little scary.”

The Supreme Court’s decision to overturn Roe v. Wade abortion rights last June threatened to derail ob.gyns. in training from pursuing the specialty or locating in states that have banned or limited abortion.

Early signals from the Dobbs v. Jackson decision suggest a potential decline in ob.gyn. residents choosing abortion-restrictive states, but some industry leaders, residents, and medical students say it may be too early to judge the full impact of the ruling because most students were already far along in their decision and application for a 2023 residency position.

At this point, some ob.gyn. students are planning careers on the basis of whether they have family ties in a particular state, whether limiting their search might hurt their potential to match in a competitive specialty, and whether their faith in the family planning and abortion training being offered by a program outweighs the drawbacks of being in a state with abortion bans or restrictions.

Lucy Brown, MD, a recent graduate of Indiana University, Indianapolis, said in an interview that she’d be “very nervous” about living and practicing in abortion-restricted Indiana if she were ready to start a family.

Dr. Brown said that she mostly limited applications in the recent Match to ob.gyn. residencies in states that protected abortion rights. Though she applied to a program in her home state of Kentucky, she noted that it – along with a program in Missouri – was very low on her rank list because of their abortion restrictions.

Ultimately, Dr. Brown matched at Johns Hopkins University, Baltimore, where she will receive abortion training and assist with abortions throughout her residency. Maryland’s abortion rights status was a big attraction, she said. “Abortion is integrated into every aspect of the education.”
 

By the numbers

For students applying to residencies this summer, evaluating the state legislative landscape is a little clearer than it was 1 year ago but is still evolving. As of June 1, 56 ob.gyn. residency programs and more than 1,100 medical residents are in states with the most restrictive bans in the country (19% of all programs), according to the Bixby Center for Reproductive Health at the University of California, San Francisco.

In terms of the latest abortion laws: 14 states banned abortion, 2 states banned abortion between 6 and 12 weeks, and 9 states banned abortion between 15 and 22 weeks, whereas abortion is legal in 25 states and Washington, according to a recent analysis by the Kaiser Family Foundation.

The impact on residencies? The Association of American Medical Colleges recently reported a 2% drop in the number of U.S. MD seniors who applied to residencies and a 5% decline in the number of seniors who applied to ob.gyn. residencies. In states where abortion was banned, the number of senior applicants to ob.gyn. programs dropped by more than 10%, according to AAMC’s Research and Action Institute.

“U.S. MD seniors appear, in general, more likely to avoid states where abortions are banned,” said Atul Grover, MD, PhD, executive director of the Research and Action Institute. “That’s a big difference between states where there are abortion bans and gestational limits and states with no bans or limits; it’s almost twice as large,” Dr. Grover said in an interview. “The question is: Was it a 1-year blip or something that will be the beginning of a trend?”

In a statement to this news organization, officials from the American College of Obstetricians and Gynecologists and the Association of Professors of Gynecology and Obstetrics said that they were aware of the AAMC data but needed to further evaluate the impact of the Dobbs ruling.

A survey released at ACOG’s annual meeting in May found that 58% of third- and fourth-year medical students were unlikely to apply to a residency program in a state with abortion restrictions. Conducted after the Dobbs ruling last year, the survey found that future physicians are choosing where to attend residency according to state abortion policies, indicating that access to abortion care is changing the landscape of medical practice.

“For personal as well as professional reasons, reproductive health care access is now a key factor in residency match decisions as a result of Dobbs,” lead author Ariana Traub, MPH, said. She studies at Emory University, Atlanta, where abortion is restricted.

“Many students, including myself, struggle when trying to decide whether to stay in restricted states where the need is greatest (highest maternal mortality, infant mortality, lower number of physicians), versus going to an unrestricted state” for more comprehensive training and care, Ms. Traub said. “Regardless of this decision, Dobbs and subsequent abortion laws are making students question what matters most and how they can provide the best care.”

In another recently published survey, University of Miami fourth-year student Morgan Levy, MD, MPH, and colleagues found that 77% of students would prefer to apply to a residency program in a state that preserves access to abortion. Ensuring access to those services for themselves or a family member was a key factor, according to the paper published in the Journal of General Internal Medicine.

For Dr. Levy, who recently graduated from a school in abortion-restricted Florida and will soon apply to ob.gyn. residencies, the Dobbs decision made her more committed to becoming an ob.gyn., an interest she’s had since college, she said.

“I do not intend to limit my search,” Dr. Levy said in an interview. “In the states where there are restrictions in place, it’s really important to make sure that people are getting good care,” she said.
 

Differing perspective

Though survey and anecdotal data show that students and residents expressing hesitation about states with bans or restrictive laws, it appears that most who applied to residency programs during the 2023 Match did not shy away from those states. Almost all the open ob.gyn. residency positions were filled, according to the National Resident Matching Program.

There was no change in how U.S. MD seniors applying for 2023 residency ranked programs on the basis of whether abortion was legal, limited, or banned in the state where a program was based, Donna Lamb, DHSc, MBA, BSN, president and CEO of the NRMP, said.

“We’re seeing what we’ve seen over the past 5 years, and that is a very high fill rate, a very high rate of preference for ob.gyn., and not a heck of a lot of change,” Dr. Lamb said, noting that ob.gyn. programs continue to be very competitive. “We have more applicants than we have positions available,” she said.

In the most recent Match, there were 2,100 applicants (more than half U.S. MD seniors) for about 1,500 slots, with 1,499 initial matches, according to NRMP data. The overall fill rate was 99.7% after the Supplemental Offer and Assistance Program and Electronic Residency Applications process, NRMP reported. The results are similar to what NRMP reported as its previous all-time high year for ob.gyn. placements.

There was a dip in applicants from 2022 to 2023, even though the slots available stayed the same, but it was not markedly different from the previous 5 years, Dr. Lamb said.

“While the Dobbs decision may, indeed, have impacted applicant and application numbers to residency programs, interventions such as signaling may also contribute to the decrease in numbers of applications submitted as well,” AnnaMarie Connolly, MD, ACOG chief of education and academic affairs, and Arthur Ollendorff, MD, APOG president, said in a statement to this news organization.

For the first time in 2022, Match Day applicants were required to “signal” interest in a particular program in an effort to reduce the number of applications and cost to medical students, they noted.

CHICAGO – For the chief patient officer of the American Cancer Society, this year’s annual meeting of the American Society of Clinical Oncology was a gem. And it didn’t just sparkle because of the sequined Taylor Swift fans clogging the nearby streets during the meeting.

Arif Kamal, MD, MBA, MHS, who is also an oncologist at Duke University, Durham, N.C., said he was impressed by a pair of landmark studies released at the meeting that show hidden cancer can be targeted with “really remarkable outcomes.” He also highlighted sessions that examined the role of artificial intelligence (AI) in oncology, during an interview.

Below are lightly edited excerpts from a conversation with Dr. Kamal:



Question: What are some of most groundbreaking studies released at ASCO?

Answer: One is an interim analysis of the NATALEE trial, which involved patients with early-stage hormone receptor-positive, HER2-negative (HR+/HER2–) breast tumors. This phase 3 randomized trial compared maintenance therapy with the cyclin-dependent kinase 4/6 (CDK4/6) inhibitor ribociclib (Kisqali) plus endocrine therapy with an aromatase inhibitor to endocrine therapy alone in patients with node-positive or node-negative and stage II or III HR+/HER– breast cancer.

For a long time, the standard care in these patients has been to use endocrine therapy alone. This is the first big trial to show that upstream usage of additional therapy in early stages is also beneficial for disease-free survival. The 3-year invasive disease-free survival rate was 90.4% in the rebociclib-endocrine therapy group vs. 87.1% for patients who received only endocrine therapy (P = .0014).



Q: How do these findings add to current knowledge?

A: Typically, we let people get metastatic disease before we use CDK4/6 inhibitors. These findings show that systemic treatment beyond endocrine therapy will be helpful in cases where you’ve got smaller disease that has not spread yet.

Even in patients with node-negative breast cancer, micrometastatic disease is clearly there, because the medication killed the negative lymph nodes.



Q: What else struck you as especially important research?

A: The NATALEE findings match what we saw in another study – the ADAURA trial, which looked at adjuvant osimertinib in non–small-cell lung cancer patients with EGFR-mutated, stage IB to IIIA disease – cancer that has not spread to the lymph nodes.

This is another example where you have a treatment being used in earlier-stage disease that’s showing really remarkable outcomes. The study found that 5-year overall survival was 88% in an osimertinib group vs. 78% in a placebo group (P < .001). This is a disease where, in stage IB, we wouldn’t even necessarily give these patients treatment at all, other than surgical resection of the tumor and maybe give them a little bit of chemotherapy.

Even in these smaller, early tumors, osimertinib makes a difference.



Q: As a whole, what are these studies telling us about cancer cells that can’t be easily detected?

A: To find a disease-free survival benefit with adding ribociclib in a stage II, stage III setting, particularly in node-negative disease, is remarkable because it says that the cells in hiding are bad actors, and they are going to cause trouble. The study shows that medications can find these cells and reverse that risk of bad outcomes.

If you think about the paradigm of cancer, that’s pretty remarkable because the ADAURA trial does the same thing: You do surgery for [early-stage] lung cancers that have not spread to the lymph nodes and you figure, “Well, I’ve got it all, right? The margins are real big, healthy, clean.” And yet, people still have recurrences, and you ask the same question: “Can any medicine find those few cells, the hundreds of cells that are still left somewhere in hiding?” And the answer is again, yes. It’s changing the paradigm of our understanding of minimal residual disease.

That’s why there’s so much interest in liquid biopsies. Let’s say that after treatment we don’t see any cancer radiologically, but there’s a signal from a liquid biopsy [detecting residual cancer]. These two trials demonstrate that there’s something we can do about it.



Q: There were quite a few studies about artificial intelligence released at ASCO. Where do we stand on that front?

A: We’re just at the beginning of people thinking about the use of generative AI for clinical decision support, clinical trial matching, and pathology review. But AI, at least for now, still has the issue of making up things that aren’t true. That’s not something patients are going to be okay with.



Q: How can AI be helpful to medical providers considering its limitations?

A: AI is going to be very good at the data-to-information transition. You’ll start seeing people use AI to start clinical notes for them and to match patients to the best clinical trials for them. But fundamentally, the clinician’s role will continue to be to check facts and offer wisdom.



Q: Will AI threaten the careers of oncologists?

A: The body of knowledge about oncology is growing exponentially, and no one can actually keep up. There’s so much data that’s out there that needs to be turned into usable information amid a shortage of oncologists. At the same time, the prevalence of cancer is going up, even though mortality is going down.

Synthesis of data is what oncologists are waiting for from AI. They’ll welcome it as opposed to being worried. That’s the sentiment I heard from my colleagues.

Growing up in south India, Deepu Madduri, MD, chose her career path to emulate an ear-nose-throat doctor who kept helping her recover. Today she belongs to a pioneering team of women hematologic oncologists who research innovative multiple myeloma treatments while mentoring the next generation of women in their field.

Inspired in childhood to study medicine, Dr. Madduri chose to specialize in oncology after losing a grandparent to cancer. After moving to the United States as a fifth grader, she went back to India every summer. While visiting as a college student, Dr. Madduri found her grandmother pale, with symptoms such as blood in the stool. Diagnosed with stage IV colon cancer, the grandmother died 6 months later.

“I realized I really wanted to be an oncologist because I wanted to see what I could have done to help my grandma,” Dr. Madduri said in an interview.

Today, as a senior medical director at Janssen Oncology, Dr. Madduri joins her colleague Lisa Kallenbach, MD, and others on a team of hematologist oncologists who are working to advance the treatment of multiple myeloma with chimeric antigen receptor (CAR) T-cell therapy. She and Dr. Kallenbach also mentor other blood cancer specialists through a company-sponsored Women in Hematology program.

Dr. Kallenbach, group medical director at the firm, had also long wanted to become a doctor. Unlike Dr. Madduri, however, Dr. Kallenbach took a “long and winding road” and didn’t start med school until age 30.

Put off by college premed requirements, Dr. Kallenbach majored in anthropology and suppressed her desire to study medicine while she got a master’s degree in public administration, worked in public health, and volunteered with the Peace Corps. Ultimately, she decided to do a postbaccalaureate program, entered Brown University in Providence, R.I., and loved it.

“No one in my family was a doctor, so it was all very mystical to me,” she said. “It wasn’t until I worked for a doctor where it was demystified, and I thought, ‘Ah, they’re not any smarter. They just work really hard, and I can work hard. I always do.’”
 

Time for a change

Hard work brought both Dr. Kallenbach and Dr. Madduri to Janssen at roughly the same time, for similar reasons.

Dr. Madduri had been a junior faculty member at Mount Sinai, where she followed her mentor’s advice and fought hard to become principal investigator of the CARTITUDE-1 trial, which she presented at the annual meetings of the American Society of Hematology in 2019 and 2020. This research led to the Food and Drug Administration’s approval of the CAR T therapy Carvykti for multiple myeloma. Dr. Madduri also launched the CAR T program at Mount Sinai and quickly gained prominence in her field, despite being the hospital’s youngest faculty member for myeloma. But when the pandemic hit, she decided to try something different.

“I was helping one person at a time as a physician, but [Janssen] gave me the opportunity to help people in a much broader sense,” said Dr. Madduri, who joined the firm in April 2021. “I’m now the one designing the trials and looking at what the needs are in myeloma.”

“Janssen’s CAR T product [Carvykti] revolutionized the space because after a one-time treatment, patients are in a deep and durable remission and living much longer,” she said. Furthermore, Janssen offered Dr. Madduri the chance to design the trials toward that long-held goal.

“I want to be part of the team where they’re really dedicated to curing myeloma,” Dr. Madduri said. And she continues to see patients as an adjunct assistant professor at Stanford (Calif.) University, where she did a blood & marrow transplantation fellowship.

Dr. Kallenbach was also drawn to Janssen because of her pandemic experiences – and the promise of broader opportunities, including a better work-life balance. One patient at a time, she was treating a variety of hematologic disorders and malignancies. Although she enjoyed it, she just needed a change.

“It had been 9 months of COVID, and it was just a really busy time and stressful,” Dr. Kallenbach said. When a friend shared the Janssen job posting, she took it as a sign. “I thought, I could really make an impact here. Now I’ve gone from treating one patient at a time to treating tons of patients and helping to get this drug [Carvykti] to patients who can really use it.”
 

A cancer field with potential

While it was Dr. Madduri’s grandmother’s illness that drew her to study oncology, she chose not to work on the colon cancer that killed her grandmother. It felt too personal, and she didn’t foresee being able to help patients in the ways she wanted. Instead of sending them to hospice when treatment options ran out, Dr. Madduri saw the myeloma landscape advancing rapidly, with more drugs becoming available.

“What really interests me is that this field is going somewhere, and we can potentially find something to cure these patients,” Dr. Madduri said. “There’s great need, but there’s rapid advancement happening as well. I wanted to go into something where I could really make a difference and help these patients that I couldn’t help before.”

She’s currently managing CARTITUDE-6, a head-to-head frontline trial testing CAR T-cell therapy (Carvykti) in patients eligible for transplant. “Right now the standard of care is transplant, so there’s a lot of excitement” with the idea of replacing transplant with CAR T in newly diagnosed patients, something that’s never been done. Dr. Madduri hopes this will move patients into deeper remission and eventually help pave the path to a cure. “We have to change the landscape. We have to push the boundaries, right?”

Similarly, Dr. Kallenbach was drawn to myeloma because of the rush of new therapies.

“From the time I was training to the time I was practicing, the treatments completely changed,” she said. “That’s always exciting when you’re making that much progress on a disease, to see these enormous changes. Now you’re actually seeing people who’ve had tons of prior therapies have responses that I’ve just never seen before.”

Dr. Kallenbach also found fulfillment through patient care. “People really connect with their oncologist, and that relationship is really special,” she said. “The other thing is that you really learn from cancer patients how to live your life, like what’s important. People’s priorities become very clear.”
 

Importance of mentorship

Both women credit part of their success to finding excellent mentors early on, and both are paying it forward by mentoring other women in their field.

Dr. Madduri met her mentor, Sundar Jagannath, MBBS, when he interviewed her at Icahn School of Medicine’s Tisch Cancer Institute in New York, where he’s director of the multiple myeloma program and the Myeloma Center of Excellence. Noting her enthusiasm and excellent training, Dr. Jagannath recruited Dr. Madduri and quickly discovered her organizational skills. When she expressed interest in running the CAR T program, he let her run with it, while advising her on how to ensure that she got respect and credit for her work.

“You have to do your part, but if you don’t have the right mentor telling you, it’d be really hard for someone who’s just starting out to know what to do,” Dr. Madduri said.

Dr. Jagannath’s guidance paid off. “When she made the ASH presentation, everybody was impressed,” he said. “She captured the attention of my peers who have been in the field for a long time, so she immediately made a national splash.”

Just a few years out of her own fellowship, Dr. Madduri had already begun mentoring other fellows. Through Women in Hematology, she helps gather data about the roles women play in her field and how to further their advancement. “The myeloma field is slowly starting to shift” toward more gender balance, she said – progress she feels happy to support.

Dr. Kallenbach’s mentoring is less formal, yet it makes a deep impact on those she takes under her wing. Her mentees are mostly the students she’s met on the Bryn Mawr College campus where she walks her two Labradors. That’s how she met Louise Breen, who, after a postbaccalaureate there, just graduated from University of Pennsylvania, Philadelphia, and is headed for residency at Mass General Hospital, Boston.

Dr. Breen said her mentor’s greatest gift has been “showing many of us that it’s possible to do it and what life could look like.” While fostering students’ self-confidence as they wrangle with imposter syndrome, Dr. Kallenbach has also demonstrated what a work-life balance in medicine can look like. She learned that from her own mentor, Hedy Smith, MD, PhD, now clinical director of inpatient hematology/oncology at MedStar Washington Hospital Center, and previously an associate professor at Tufts Medical Center.

Dr. Kallenbach quickly made an impression on Dr. Smith by coming to her door in tears one day.

“She was so devastated at the additions I made in her notes,” recalled Dr. Smith. “She felt that she had presented me with this less-than-adequate document. ... I told her, ‘this really says the world about who you are, who you’re going to become in oncology.’ I was struck by her character, a dedication to her work, and her desire to perfect it.”

Three years later, Dr. Smith remembers Dr. Kallenbach coming to her office with a big smile and saying: “Look at this. You didn’t make any changes.” Then Dr. Smith knew that her mentee was ready for the next chapter of her career.

They have kept in touch, with Dr. Kallenbach periodically calling to discuss a difficult case or to plan to meet up at conferences. “It always puts a smile on my face because this person who was once my student has now undergone this metamorphosis, and here we are, now truly equals and colleagues attending the meetings together,” Dr. Smith remarked.

Dr. Kallenbach feels grateful about finding a strong female mentor early in her medical career, especially given some of the everyday sexism she has encountered. A male colleague at a conference once expressed shock that she was practicing medicine full time while also being a mother. Dr. Kallenbach hasn’t encountered such attitudes while working in the pharmaceutical industry.

“I feel more valued as a doctor now than I ever did in practice,” she said. While before, she felt respected, “here, I feel like your expertise is valued, and you can actually help shape programs and inform how doctors practice.”

Dr. Madduri, too, feels like she’s where she’s supposed to be. “I went into the field because I really wanted to help people and make a difference,” she said. “I’m doing everything that I wanted to do.”

Growing up in south India, Deepu Madduri, MD, chose her career path to emulate an ear-nose-throat doctor who kept helping her recover. Today she belongs to a pioneering team of women hematologic oncologists who research innovative multiple myeloma treatments while mentoring the next generation of women in their field.

Inspired in childhood to study medicine, Dr. Madduri chose to specialize in oncology after losing a grandparent to cancer. After moving to the United States as a fifth grader, she went back to India every summer. While visiting as a college student, Dr. Madduri found her grandmother pale, with symptoms such as blood in the stool. Diagnosed with stage IV colon cancer, the grandmother died 6 months later.

“I realized I really wanted to be an oncologist because I wanted to see what I could have done to help my grandma,” Dr. Madduri said in an interview.

Today, as a senior medical director at Janssen Oncology, Dr. Madduri joins her colleague Lisa Kallenbach, MD, and others on a team of hematologist oncologists who are working to advance the treatment of multiple myeloma with chimeric antigen receptor (CAR) T-cell therapy. She and Dr. Kallenbach also mentor other blood cancer specialists through a company-sponsored Women in Hematology program.

Dr. Kallenbach, group medical director at the firm, had also long wanted to become a doctor. Unlike Dr. Madduri, however, Dr. Kallenbach took a “long and winding road” and didn’t start med school until age 30.

Put off by college premed requirements, Dr. Kallenbach majored in anthropology and suppressed her desire to study medicine while she got a master’s degree in public administration, worked in public health, and volunteered with the Peace Corps. Ultimately, she decided to do a postbaccalaureate program, entered Brown University in Providence, R.I., and loved it.

“No one in my family was a doctor, so it was all very mystical to me,” she said. “It wasn’t until I worked for a doctor where it was demystified, and I thought, ‘Ah, they’re not any smarter. They just work really hard, and I can work hard. I always do.’”

Three big bumps on the weight-loss journey

The search for the Holy Grail. The destruction of the One Ring. The never-ending struggle to Lose Weight.

Like most legendary quests, weight loss is a journey, and we need support to help us achieve our goal. Maybe it’s gaining a new workout partner or finding a similarly-goaled Facebook Group. For a lot of people, it’s as simple as your friends and family. A recent study, however, suggests that the people closest to you may be your worst weight-loss enemies, and they might not even know it.

Spencer Davis/Unsplash

Researchers at the University of Surrey reviewed the literature on the positives and negatives of social support when it comes to weight loss and identified three types of negative effects: acts of sabotage, feeding behavior, and collusion.

Let’s start with the softest of intentions and work our way up. Collusion is the least negative. Friends and family may just go with the flow, even if it doesn’t agree with the goals of the person who’s trying to lose weight. It can even happen when health care professionals try to help their patients navigate or avoid obesity, ultimately killing with kindness, so to speak.

Next up, feeding behavior. Maybe you know someone whose love language is cooking. There are also people who share food because they don’t want to waste it or because they’re trying to be polite. They act out of the goodness of their hearts, but they’re putting up roadblocks to someone’s goals. These types of acts are usually one-sided, the researchers found. Remember, it’s okay to say, “No thanks.”

The last method, sabotage, is the most sinister. The saboteur may discourage others from eating healthy, undermine their efforts to be physically active, or take jabs at their confidence or self-esteem. Something as simple as criticizing someone for eating a salad or refusing to go on a walk with them can cause a setback.

“We need to explore this area further to develop interventions which could target family and friends and help them be more supportive in helping those they are close to lose weight,” said lead author Jane Odgen, PhD, of the University of Surrey, Guildford, England.

Like we said before, weight loss is a journey. The right support can only improve the odds of success.
 

Robots vs. mosquitoes

If there’s one thing robots are bad at, it’s giving solid mental health advice to people in crisis. If there’s one thing robots are very, very good at, it’s causing apocalypses. And joyous day for humanity, this time we’re not the ones being apocalypsed.

Yet.

Liu et al., 2023, PLOS Neglected Tropical Diseases, CC-BY 4.0

Taiwan has a big mosquito problem. Not only do the mosquitoes in Taiwan carry dengue – among other dangerous diseases – but they’ve urbanized. Not urbanized in the sense that they’ve acquired a taste for organic coffee and avocado toast (that would be the millennial mosquito, a separate but even more terrifying creature), but more that they’ve adapted to reproduce literally anywhere and everywhere. Taiwanese mosquitoes like to breed in roadside sewer ditches, and this is where our genocidal robot comes in.

To combat the new, dangerous form of street-savvy mosquito, researchers built a robot armed with both insecticide and high-temperature, high-pressure water jets and sent it into the sewers of Kaohsiung City. The robot’s goal was simple: Whenever it came across signs of heavy mosquito breeding – eggs, larvae, pupae, and so on – the robot went to work. Utilizing both its primary weapons, the robot scrubbed numerous breeding sites across the city clean.

The researchers could just sit back and wait to see how effective their robot was. In the immediate aftermath, at various monitoring sites placed alongside the ditches, adult mosquito density fell by two-thirds in areas targeted by the robot. That’s nothing to sniff at, and it does make sense. After all, mosquitoes are quite difficult to kill in their adult stage, why not target them when they’re young and basically immobile?

The researchers saw promise with their mosquito-killing robot, but we’ve noticed a rather large issue. Killing two-thirds of mosquitoes is fine, but the third that’s left will be very angry. Very angry indeed. After all, we’re targeting the mosquito equivalent of children. Let’s hope our mosquito Terminator managed to kill mosquito Sarah Connor, or we’re going to have a big problem on our hands a bit later down the line.
 

This is knot what you were expecting

Physicians who aren’t surgeons probably don’t realize it, but the big thing that’s been getting between the knot-tying specialists and perfect suturing technique all these years is a lack of physics. Don’t believe us? Well, maybe you’ll believe plastic surgeon Samia Guerid, MD, of Lausanne, Switzerland: “The lack of physics-based analysis has been a limitation.” Nuff said.

Alain Herzog / EPFL

That’s not enough for you, is it? Fine, we were warned.

Any surgical knot, Dr. Guerid and associates explained in a written statement, involves the “complex interplay” between six key factors: topology, geometry, elasticity, contact, friction, and polymer plasticity of the suturing filament. The strength of a suture “depends on the tension applied during the tying of the knot, [which] permanently deforms, or stretches the filament, creating a holding force.” Not enough tension and the knot comes undone, while too much snaps the filament.

For the experiment, Dr. Guerid tied a few dozen surgical knots, which were then scanned using x-ray micro–computed tomography to facilitate finite element modeling with a “3D continuum-level constitutive model for elastic-viscoplastic mechanical behavior” – no, we have no idea what that means, either – developed by the research team.

That model, and a great deal of math – so much math – allowed the researchers to define a threshold between loose and tight knots and uncover “relationships between knot strength and pretension, friction, and number of throws,” they said.

But what about the big question? The one about the ideal amount of tension? You may want to sit down. The answer to the ultimate question of the relationship between knot pretension and strength is … Did we mention that the team had its own mathematician? Their predictive model for safe knot-tying is … You’re not going to like this. The best way to teach safe knot-tying to both trainees and robots is … not ready yet.

The secret to targeting the knot tension sweet spot, for now, anyway, is still intuition gained from years of experience. Nobody ever said science was perfect … or easy … or quick.

Three big bumps on the weight-loss journey

The search for the Holy Grail. The destruction of the One Ring. The never-ending struggle to Lose Weight.

Like most legendary quests, weight loss is a journey, and we need support to help us achieve our goal. Maybe it’s gaining a new workout partner or finding a similarly-goaled Facebook Group. For a lot of people, it’s as simple as your friends and family. A recent study, however, suggests that the people closest to you may be your worst weight-loss enemies, and they might not even know it.

Researchers at the University of Surrey reviewed the literature on the positives and negatives of social support when it comes to weight loss and identified three types of negative effects: acts of sabotage, feeding behavior, and collusion.

Let’s start with the softest of intentions and work our way up. Collusion is the least negative. Friends and family may just go with the flow, even if it doesn’t agree with the goals of the person who’s trying to lose weight. It can even happen when health care professionals try to help their patients navigate or avoid obesity, ultimately killing with kindness, so to speak.

Next up, feeding behavior. Maybe you know someone whose love language is cooking. There are also people who share food because they don’t want to waste it or because they’re trying to be polite. They act out of the goodness of their hearts, but they’re putting up roadblocks to someone’s goals. These types of acts are usually one-sided, the researchers found. Remember, it’s okay to say, “No thanks.”

The last method, sabotage, is the most sinister. The saboteur may discourage others from eating healthy, undermine their efforts to be physically active, or take jabs at their confidence or self-esteem. Something as simple as criticizing someone for eating a salad or refusing to go on a walk with them can cause a setback.

“We need to explore this area further to develop interventions which could target family and friends and help them be more supportive in helping those they are close to lose weight,” said lead author Jane Odgen, PhD, of the University of Surrey, Guildford, England.

Like we said before, weight loss is a journey. The right support can only improve the odds of success.
 

Robots vs. mosquitoes

If there’s one thing robots are bad at, it’s giving solid mental health advice to people in crisis. If there’s one thing robots are very, very good at, it’s causing apocalypses. And joyous day for humanity, this time we’re not the ones being apocalypsed.

Yet.

Taiwan has a big mosquito problem. Not only do the mosquitoes in Taiwan carry dengue – among other dangerous diseases – but they’ve urbanized. Not urbanized in the sense that they’ve acquired a taste for organic coffee and avocado toast (that would be the millennial mosquito, a separate but even more terrifying creature), but more that they’ve adapted to reproduce literally anywhere and everywhere. Taiwanese mosquitoes like to breed in roadside sewer ditches, and this is where our genocidal robot comes in.

To combat the new, dangerous form of street-savvy mosquito, researchers built a robot armed with both insecticide and high-temperature, high-pressure water jets and sent it into the sewers of Kaohsiung City. The robot’s goal was simple: Whenever it came across signs of heavy mosquito breeding – eggs, larvae, pupae, and so on – the robot went to work. Utilizing both its primary weapons, the robot scrubbed numerous breeding sites across the city clean.

The researchers could just sit back and wait to see how effective their robot was. In the immediate aftermath, at various monitoring sites placed alongside the ditches, adult mosquito density fell by two-thirds in areas targeted by the robot. That’s nothing to sniff at, and it does make sense. After all, mosquitoes are quite difficult to kill in their adult stage, why not target them when they’re young and basically immobile?

The researchers saw promise with their mosquito-killing robot, but we’ve noticed a rather large issue. Killing two-thirds of mosquitoes is fine, but the third that’s left will be very angry. Very angry indeed. After all, we’re targeting the mosquito equivalent of children. Let’s hope our mosquito Terminator managed to kill mosquito Sarah Connor, or we’re going to have a big problem on our hands a bit later down the line.
 

This is knot what you were expecting

Physicians who aren’t surgeons probably don’t realize it, but the big thing that’s been getting between the knot-tying specialists and perfect suturing technique all these years is a lack of physics. Don’t believe us? Well, maybe you’ll believe plastic surgeon Samia Guerid, MD, of Lausanne, Switzerland: “The lack of physics-based analysis has been a limitation.” Nuff said.

Chronic pulmonary disease continues to be a major cause of morbidity and mortality in individuals living with the human immunodeficiency virus, even with optimal HIV control. And this is independent, as seen in many studies, of age, smoking, and pulmonary infections.

Both chronic pulmonary obstructive disease (COPD) and lung cancer occur more frequently in people living with HIV than in the general population, and at earlier ages, and with worse outcomes. The risk for emphysema and interstitial lung abnormalities also appears to be higher, research has shown. And asthma has also recently emerged as another important lung disease in people with HIV (PWH).

“There is evidence that the severity of immunocompromise associated with HIV infection is linked with chronic lung diseases. People who have a lower CD4 cell count or a higher viral load do have an increased risk of COPD and emphysema as well as potentially lung cancer. But [while] immunocompromise plays a role, it isn’t the only story, given that even with well-controlled HIV there is increased risk,” said Kristina Crothers, MD, professor in the division of pulmonary, critical care, and sleep medicine at the University of Washington, Seattle.

Research has evolved from a focus on the epidemiology of HIV-related chronic lung diseases to a current emphasis on “trying to understand further the mechanisms [behind the heightened risk] through more benchwork and corollary translational studies, and then to the next level of trying to understand what this means for how we should manage people with HIV who have chronic lung diseases,” Dr. Crothers said. “Should management be tailored for people with HIV infection?”

Impairments in immune pathways, local and systemic inflammation, oxidative stress, dysbiosis, and accelerated cellular senescence are among potential mechanisms, but until ongoing mechanistic research yields more answers, pulmonologists should simply – but importantly – be aware of the increased risk and have a low threshold for investigating respiratory symptoms, she and other experts said in interviews. Referral of eligible patients for lung cancer screening is also a priority, as is smoking cessation, they said.

Notably, while spirometry has been the most commonly studied lung function measure in PWH, another noninvasive measure, diffusing capacity for carbon monoxide (DLCO), has garnered attention in the past decade and thus far appears to be the more frequent lung function abnormality.

In an analysis published in 2020 from the longitudinal Multicenter AIDS Cohort Study (MACS) – a study of a subcohort of 591 men with HIV and 476 without HIV – those with HIV were found to have a 1.6-fold increased risk of mild DLCO impairment (< 80% of predicted normal) and a 3-fold higher risk of more severe DLCO impairment (< 60% of predicted normal). There was no significant difference in spirometry findings by HIV status.

Such findings on DLCO are worthy of consideration in clinical practice, even in the absence of HIV-specific screening guidelines for noncommunicable lung diseases, Dr. Crothers said. “In thinking about screening and diagnosing chronic lung diseases in these patients, I’d not only consider spirometry, but also diffusing capacity” when possible, she said. Impaired DLCO is seen with emphysema and pulmonary vascular diseases like pulmonary hypertension and also interstitial lung diseases.
 

Key chronic lung diseases

Ken M. Kunisaki, MD, MS, associate professor of medicine at the University of Minnesota, Minneapolis, and the first author of the MACS analysis of lung function – one of the most recent and largest reports of DLCO impairment – points out that studies of chest computed tomography (CT) have also documented higher rates of emphysema and interstitial lung abnormalities.

A chest CT analysis from a cohort in Denmark (the Copenhagen Comorbidity in HIV Infection [COCOMO] cohort) found interstitial lung abnormalities in 10.9% of more than 700 PWH which represented a 1.8-fold increased risk compared to HIV-negative controls. And a study from an Italian sample of never-smoking PWH and controls reported emphysema in 18% and 4%, respectively. These studies, which did not measure DLCO, are among those discussed in a 2021 review by Dr. Kunisaki of advances in HIV-associated chronic lung disease research.

COPD is the best studied and most commonly encountered chronic lung disease in PWH. “Particularly for COPD, what’s both interesting and unfortunate is that we haven’t really seen any changes in the epidemiology with ART (antiretroviral therapy) – we’re still seeing the same findings, like the association of HIV with worse COPD at younger ages,” said Alison Morris, MD, MS, professor of medicine, immunology, and clinical and translational research at the University of Pittsburgh. “It doesn’t seem to have improved.”

Its prevalence has varied widely from cohort to cohort, from as low as 3% (similar to the general population) to over 40%, Dr. Kunisaki said, emphasizing that many studies, including studies showing higher rates, have controlled for current and past smoking. In evaluating patients with low or no smoking burden, “don’t discount respiratory symptoms as possibly reflecting underlying lung disease because COPD can develop with low to no smoking history in those with HIV,” he advised.

A better understanding of how a chronic viral infection like HIV leads to heightened COPD risk will not only help those with HIV, he notes, but also people without HIV who have COPD but have never smoked – a woefully underappreciated and understudied population. Ongoing research, he said, “should help us understand COPD pathogenesis generally.”

Research on asthma is relatively limited thus far, but it does appear that PWH may be more prone to developing severe asthma, just as with COPD, said Dr. Kunisaki, also a staff physician at the Minneapolis Veterans Administration Health Care System. Research has shown, for instance, that people with HIV more frequently needed aggressive respiratory support when hospitalized for asthma exacerbations.

It’s unclear how much of this potentially increased severity is attributable to the biology of HIV’s impact on the body and how much relates to social factors like disparities in income and access to care, Dr. Kunisaki said, noting that the same questions apply to the more frequent COPD exacerbations documented in PWH.

Dr. Crothers points out that, while most studies do not suggest a difference in the incidence of asthma in PWH, “there is some data from researchers looking at asthma profiles [suggesting] that the biomarkers associated with asthma may be different in people with and without HIV,” signaling potentially different molecular or biologic underpinnings of the disease.

Incidence rates of lung cancer in PWH, meanwhile, have declined over the last 2 decades, but lung cancer remains the leading cause of cancer-related mortality in PWH and occurs at a rate that is 2-2.5 times higher than that of individuals not infected with HIV, according to

Janice Leung, MD, of the division of respiratory medicine at the University of British Columbia and the Centre for Heart Lung Innovation at St. Paul’s Hospital in Vancouver.

Patients with HIV have “worse outcomes overall and a higher risk of mortality, even when presenting at the same stage,” said Dr. Leung, who reviewed trends in COPD and lung cancer in a recently published opinion piece.
 

Potential drivers

A bird’s eye view of potential – and likely interrelated – mechanisms for chronic lung disease includes chronic immune activation that impairs innate and adaptive immune pathways; chronic inflammation systemically and in the lung despite viral suppression; persistence of the virus in latent reservoirs in the lung, particularly in alveolar macrophages and T cells; HIV-related proteins contributing to oxidative stress; accelerated cellular aging; dysbiosis; and ongoing injury from inhaled toxins.

All are described in the literature and are being further explored. “It’s likely that multiple pathways are playing a role,” said Dr. Crothers, “and it could be that the balance of one to another leads to different manifestations of disease.”

Biomarkers that have been elevated and associated with different features of chronic lung disease – such as airflow obstruction, low DLCO, and emphysema – include markers of inflammation (e.g., C-reactive protein, interleukin-6), monocyte activation (e.g., soluble CD14), and markers of endothelial dysfunction, she noted in a 2021 commentary marking 40 years since the first reported cases of acquired immunodeficiency syndrome.

In her laboratory, Dr. Leung is using new epigenetic markers to look at the pathogenesis of accelerated aging in the lung. By profiling bronchial epithelial brushings for DNA methylation and gene expression, they have found that “people living with both HIV and COPD have the fastest epigenetic age acceleration in their airway epithelium,” she said. The findings “suggest that the HIV lung is aging faster.”

They reported their findings in 2022, describing methylation disruptions along age-related pathways such as cellular senescence, longevity regulation, and insulin signaling.

Dr. Leung and her team have also studied the lung microbiome and found lower microbial diversity in the airway epithelium in patients with HIV than those without, especially in those with HIV and COPD. The National Institutes of Health–sponsored Lung HIV Microbiome Project found that changes in the lung microbiome are most pronounced in patients who haven’t yet initiated ART, but research in her lab suggests ongoing suppression of microbial diversity even after ART, she said.

Dr. Morris is particularly interested in the oral microbiome, having found through her research that changes in the oral microbiome in PWH were more related to impaired lung function than alterations in the lung and gut microbiome. “That may be in part because of the way we measure things,” she said. “But we also think that the oral microbiome probably seeds the lung [through micro-aspiration].” A study published in 2020 from the Pittsburgh site of the MACS described alterations in oral microbial communities in PWH with abnormal lung function.

Preliminary research suggests that improved dental cleaning and periodontal work in PWH and COPD may influence the severity of COPD, she noted.

“We don’t see as much of a signal with the gut microbiome [and HIV status or lung function], though there could still be ways in which gut microbiome influences the lung,” through systemic inflammation, the release of metabolites into the bloodstream, or microbial translocation, for instance, she said.

The potential role of translocation of members of the microbiome, in fact, is an area of active research for Dr. Morris. Members of the microbiome – viruses and fungi in addition to bacteria – “can get into the bloodstream from the mouth, from the lung, from the gut, to stimulate inflammation and worsen lung disease,” she said.
 

Key questions in an evolving research landscape

Dr. Kunisaki looks forward to research providing a more longitudinal look at lung function decline– a move beyond a dominance of cross-sectional studies – as well as research that is more comprehensive, with simultaneous collection of various functional measures (eg., DLCO with chest imaging and fractional excretion of nitric oxide (FENO – a standardized breath measure of Th2 airway inflammation).

The several-year-old NIH-supported MACS/WIHS (Women’s Interagency HIV Study) Combined Cohort study, in which Dr. Kunisaki and Dr. Morris participate, aims in part to identity biomarkers of increased risk for chronic lung disease and other chronic disorders and to develop strategies for more effective interventions and treatments.

Researchers will also share biospecimens, “which will allow more mechanistic work,” Dr. Kunisaki noted. (The combined cohort study includes participants from the earlier, separate MACS and WIHS studies.)

Questions about treatment strategies include the risks versus benefits of inhaled corticosteroids, which may increase an already elevated risk of respiratory infections like bacterial pneumonia in PWH, Dr. Kunisaki said.

[An aside: Inhaled corticosteroids also have well-described interactions with ART regimens that contain CYP3A4 inhibitors (e.g., ritonavir and cobicistat) that can lead to hypercortisolism. In patients who require both types of drugs, he said, beclomethasone has the least interactions and is the preferred inhaled corticosteroid.]

For Dr. Crothers, unanswered critical questions include – as she wrote in her 2021 commentary – the question of how guidelines for the management of COPD and asthma should be adapted for PWH. Is COPD in PWH more or less responsive to inhaled corticosteroids, for instance? And are antifibrotic treatments for interstitial lung disease and immunotherapies for asthma or lung cancer similarly effective, and are there any increased risks for harms in people with HIV?

There’s also the question of whether PWH should be screened for lung cancer earlier and with a lower smoking exposure than is advised under current guidelines for the general population, she said in the interview. “And should the approach to shared decision-making be modified for people with HIV?” she said. “We’re doing some work on these questions” right now.

None of the researchers interviewed reported any conflicts of interest relevant to the story. Dr. Kunisaki reported that he has no relevant disclosures, and said that his comments are his personal views and not official views of the U.S. Government, Department of Veterans Affairs, the Minneapolis VA, or the University of Minnesota.

The National Institutes of Health–sponsored Lung HIV Microbiome Project found that changes in the lung microbiome are most pronounced in patients who haven’t yet initiated ART, but research in her lab suggests ongoing suppression of microbial diversity even after ART, she said.

Dr. Morris is particularly interested in the oral microbiome, having found through her research that changes in the oral microbiome in PWH were more related to impaired lung function than alterations in the lung and gut microbiome. “That may be in part because of the way we measure things,” she said. “But we also think that the oral microbiome probably seeds the lung [through micro-aspiration].” A study published in 2020 from the Pittsburgh site of the MACS described alterations in oral microbial communities in PWH with abnormal lung function.

Preliminary research suggests that improved dental cleaning and periodontal work in PWH and COPD may influence the severity of COPD, she noted.

“We don’t see as much of a signal with the gut microbiome [and HIV status or lung function], though there could still be ways in which gut microbiome influences the lung,” through systemic inflammation, the release of metabolites into the bloodstream, or microbial translocation, for instance, she said.

The potential role of translocation of members of the microbiome, in fact, is an area of active research for Dr. Morris. Members of the microbiome – viruses and fungi in addition to bacteria – “can get into the bloodstream from the mouth, from the lung, from the gut, to stimulate inflammation and worsen lung disease,” she said.
 

Key questions in an evolving research landscape

Dr. Kunisaki looks forward to research providing a more longitudinal look at lung function decline– a move beyond a dominance of cross-sectional studies – as well as research that is more comprehensive, with simultaneous collection of various functional measures (eg., DLCO with chest imaging and fractional excretion of nitric oxide (FENO – a standardized breath measure of Th2 airway inflammation).

The several-year-old NIH-supported MACS/WIHS (Women’s Interagency HIV Study) Combined Cohort study, in which Dr. Kunisaki and Dr. Morris participate, aims in part to identity biomarkers of increased risk for chronic lung disease and other chronic disorders and to develop strategies for more effective interventions and treatments.

Researchers will also share biospecimens, “which will allow more mechanistic work,” Dr. Kunisaki noted. (The combined cohort study includes participants from the earlier, separate MACS and WIHS studies.)

Questions about treatment strategies include the risks versus benefits of inhaled corticosteroids, which may increase an already elevated risk of respiratory infections like bacterial pneumonia in PWH, Dr. Kunisaki said.

[An aside: Inhaled corticosteroids also have well-described interactions with ART regimens that contain CYP3A4 inhibitors (e.g., ritonavir and cobicistat) that can lead to hypercortisolism. In patients who require both types of drugs, he said, beclomethasone has the least interactions and is the preferred inhaled corticosteroid.]

For Dr. Crothers, unanswered critical questions include – as she wrote in her 2021 commentary – the question of how guidelines for the management of COPD and asthma should be adapted for PWH. Is COPD in PWH more or less responsive to inhaled corticosteroids, for instance? And are antifibrotic treatments for interstitial lung disease and immunotherapies for asthma or lung cancer similarly effective, and are there any increased risks for harms in people with HIV?

There’s also the question of whether PWH should be screened for lung cancer earlier and with a lower smoking exposure than is advised under current guidelines for the general population, she said in the interview. “And should the approach to shared decision-making be modified for people with HIV?” she said. “We’re doing some work on these questions” right now.

None of the researchers interviewed reported any conflicts of interest relevant to the story. Dr. Kunisaki reported that he has no relevant disclosures, and said that his comments are his personal views and not official views of the U.S. Government, Department of Veterans Affairs, the Minneapolis VA, or the University of Minnesota.

Chronic pulmonary disease continues to be a major cause of morbidity and mortality in individuals living with the human immunodeficiency virus, even with optimal HIV control. And this is independent, as seen in many studies, of age, smoking, and pulmonary infections.

Both chronic pulmonary obstructive disease (COPD) and lung cancer occur more frequently in people living with HIV than in the general population, and at earlier ages, and with worse outcomes. The risk for emphysema and interstitial lung abnormalities also appears to be higher, research has shown. And asthma has also recently emerged as another important lung disease in people with HIV (PWH).

“There is evidence that the severity of immunocompromise associated with HIV infection is linked with chronic lung diseases. People who have a lower CD4 cell count or a higher viral load do have an increased risk of COPD and emphysema as well as potentially lung cancer. But [while] immunocompromise plays a role, it isn’t the only story, given that even with well-controlled HIV there is increased risk,” said Kristina Crothers, MD, professor in the division of pulmonary, critical care, and sleep medicine at the University of Washington, Seattle.

Research has evolved from a focus on the epidemiology of HIV-related chronic lung diseases to a current emphasis on “trying to understand further the mechanisms [behind the heightened risk] through more benchwork and corollary translational studies, and then to the next level of trying to understand what this means for how we should manage people with HIV who have chronic lung diseases,” Dr. Crothers said. “Should management be tailored for people with HIV infection?”

Impairments in immune pathways, local and systemic inflammation, oxidative stress, dysbiosis, and accelerated cellular senescence are among potential mechanisms, but until ongoing mechanistic research yields more answers, pulmonologists should simply – but importantly – be aware of the increased risk and have a low threshold for investigating respiratory symptoms, she and other experts said in interviews. Referral of eligible patients for lung cancer screening is also a priority, as is smoking cessation, they said.

Notably, while spirometry has been the most commonly studied lung function measure in PWH, another noninvasive measure, diffusing capacity for carbon monoxide (DLCO), has garnered attention in the past decade and thus far appears to be the more frequent lung function abnormality.

In an analysis published in 2020 from the longitudinal Multicenter AIDS Cohort Study (MACS) – a study of a subcohort of 591 men with HIV and 476 without HIV – those with HIV were found to have a 1.6-fold increased risk of mild DLCO impairment (< 80% of predicted normal) and a 3-fold higher risk of more severe DLCO impairment (< 60% of predicted normal). There was no significant difference in spirometry findings by HIV status.

Such findings on DLCO are worthy of consideration in clinical practice, even in the absence of HIV-specific screening guidelines for noncommunicable lung diseases, Dr. Crothers said. “In thinking about screening and diagnosing chronic lung diseases in these patients, I’d not only consider spirometry, but also diffusing capacity” when possible, she said. Impaired DLCO is seen with emphysema and pulmonary vascular diseases like pulmonary hypertension and also interstitial lung diseases.
 

Key chronic lung diseases

Ken M. Kunisaki, MD, MS, associate professor of medicine at the University of Minnesota, Minneapolis, and the first author of the MACS analysis of lung function – one of the most recent and largest reports of DLCO impairment – points out that studies of chest computed tomography (CT) have also documented higher rates of emphysema and interstitial lung abnormalities.

A chest CT analysis from a cohort in Denmark (the Copenhagen Comorbidity in HIV Infection [COCOMO] cohort) found interstitial lung abnormalities in 10.9% of more than 700 PWH which represented a 1.8-fold increased risk compared to HIV-negative controls. And a study from an Italian sample of never-smoking PWH and controls reported emphysema in 18% and 4%, respectively. These studies, which did not measure DLCO, are among those discussed in a 2021 review by Dr. Kunisaki of advances in HIV-associated chronic lung disease research.

COPD is the best studied and most commonly encountered chronic lung disease in PWH. “Particularly for COPD, what’s both interesting and unfortunate is that we haven’t really seen any changes in the epidemiology with ART (antiretroviral therapy) – we’re still seeing the same findings, like the association of HIV with worse COPD at younger ages,” said Alison Morris, MD, MS, professor of medicine, immunology, and clinical and translational research at the University of Pittsburgh. “It doesn’t seem to have improved.”

Its prevalence has varied widely from cohort to cohort, from as low as 3% (similar to the general population) to over 40%, Dr. Kunisaki said, emphasizing that many studies, including studies showing higher rates, have controlled for current and past smoking. In evaluating patients with low or no smoking burden, “don’t discount respiratory symptoms as possibly reflecting underlying lung disease because COPD can develop with low to no smoking history in those with HIV,” he advised.

A better understanding of how a chronic viral infection like HIV leads to heightened COPD risk will not only help those with HIV, he notes, but also people without HIV who have COPD but have never smoked – a woefully underappreciated and understudied population. Ongoing research, he said, “should help us understand COPD pathogenesis generally.”

Research on asthma is relatively limited thus far, but it does appear that PWH may be more prone to developing severe asthma, just as with COPD, said Dr. Kunisaki, also a staff physician at the Minneapolis Veterans Administration Health Care System. Research has shown, for instance, that people with HIV more frequently needed aggressive respiratory support when hospitalized for asthma exacerbations.

It’s unclear how much of this potentially increased severity is attributable to the biology of HIV’s impact on the body and how much relates to social factors like disparities in income and access to care, Dr. Kunisaki said, noting that the same questions apply to the more frequent COPD exacerbations documented in PWH.

Dr. Crothers points out that, while most studies do not suggest a difference in the incidence of asthma in PWH, “there is some data from researchers looking at asthma profiles [suggesting] that the biomarkers associated with asthma may be different in people with and without HIV,” signaling potentially different molecular or biologic underpinnings of the disease.

Incidence rates of lung cancer in PWH, meanwhile, have declined over the last 2 decades, but lung cancer remains the leading cause of cancer-related mortality in PWH and occurs at a rate that is 2-2.5 times higher than that of individuals not infected with HIV, according to

Janice Leung, MD, of the division of respiratory medicine at the University of British Columbia and the Centre for Heart Lung Innovation at St. Paul’s Hospital in Vancouver.

Patients with HIV have “worse outcomes overall and a higher risk of mortality, even when presenting at the same stage,” said Dr. Leung, who reviewed trends in COPD and lung cancer in a recently published opinion piece.
 

Potential drivers

A bird’s eye view of potential – and likely interrelated – mechanisms for chronic lung disease includes chronic immune activation that impairs innate and adaptive immune pathways; chronic inflammation systemically and in the lung despite viral suppression; persistence of the virus in latent reservoirs in the lung, particularly in alveolar macrophages and T cells; HIV-related proteins contributing to oxidative stress; accelerated cellular aging; dysbiosis; and ongoing injury from inhaled toxins.

All are described in the literature and are being further explored. “It’s likely that multiple pathways are playing a role,” said Dr. Crothers, “and it could be that the balance of one to another leads to different manifestations of disease.”

Biomarkers that have been elevated and associated with different features of chronic lung disease – such as airflow obstruction, low DLCO, and emphysema – include markers of inflammation (e.g., C-reactive protein, interleukin-6), monocyte activation (e.g., soluble CD14), and markers of endothelial dysfunction, she noted in a 2021 commentary marking 40 years since the first reported cases of acquired immunodeficiency syndrome.

In her laboratory, Dr. Leung is using new epigenetic markers to look at the pathogenesis of accelerated aging in the lung. By profiling bronchial epithelial brushings for DNA methylation and gene expression, they have found that “people living with both HIV and COPD have the fastest epigenetic age acceleration in their airway epithelium,” she said. The findings “suggest that the HIV lung is aging faster.”

They reported their findings in 2022, describing methylation disruptions along age-related pathways such as cellular senescence, longevity regulation, and insulin signaling.

Dr. Leung and her team have also studied the lung microbiome and found lower microbial diversity in the airway epithelium in patients with HIV than those without, especially in those with HIV and COPD.

Johnna Mendenall had never been “the skinny friend,” she said, but the demands of motherhood – along with a sedentary desk job – made weight management even more difficult. Worried that family type 2 diabetes would catch up with her, she decided to start Wegovy shots for weight loss.

She was nervous about potential side effects. It took 5 days of staring at the Wegovy pen before she worked up the nerve for her first .25-milligram shot. And sure enough, the side effects came on strong.

“The nausea kicked in,” she said. “When I increased my dose to 1 milligram, I spent the entire night from 10 p.m. to 5 a.m. vomiting. I almost quit that day.”

Ms. Mendenall is among a growing number of people sharing personal stories online about the weight loss medication Wegovy – and similar drugs – delving into their sometimes unpleasant, and potentially gut-wrenching, side effects. 

While gastrointestinal (GI) symptoms seem to be the most common, a laundry list of others has been discussed in the news, on TikTok, and across online forums. Those include “Ozempic face,” or the gaunt look some get after taking the medication, along with hair loss, anxiety, depression, and debilitating fatigue. 

Ms. Mendenall’s primary side effects have been vomiting, fatigue, and severe constipation, but she has also seen some positive changes: The “food noise,” or the urge to eat when she isn’t hungry, is gone. Since her first dose 12 weeks ago, she has gone from 236 pounds to 215. 
 

Warning label

Wegovy’s active ingredient, semaglutide, mimics the role of a natural hormone called glucagonlike peptide–1 (GLP-1), which helps you feel well fed. Semaglutide is used at a lower dose under the brand name Ozempic, which is approved for type 2 diabetes and used off-label for weight loss.  

Both Ozempic and Wegovy come with a warning label for potential side effects, the most common ones being nausea, diarrhea, stomach pain, and vomiting.

With the surging popularity of semaglutide, more people are getting prescriptions through telemedicine companies, forgoing more in-depth consultations, leading to more side effects, said Caroline Apovian, MD, professor of medicine at Harvard Medical School and codirector of the Center for Weight Management and Wellness at Brigham and Women’s Hospital, Boston.

Specialists say starting with low doses and gradually increasing over time helps avoid side effects, but insurance companies often require a faster timeline to continue covering the medication, Dr. Apovian said. 

“Insurance companies are practicing medicine for us by demanding the patient go up in dosage [too quickly],” she explained. 

Ms. Mendenall’s insurance has paid for her Wegovy shots, but without that coverage, she said it would cost her $1,200 per month. 

There are similar medications on the market, such as liraglutide, sold under the name Saxenda. But it is a daily, rather than a weekly, shot and also comes with side effects and has been shown to be less effective. In one clinical trial, the people being studied saw their average body weight over 68 weeks drop by 15.8% with semaglutide, and by 6.4% with liraglutide.

Tirzepatide, branded Mounjaro – a type 2 diabetes drug made by Eli Lilly that may soon gain Food and Drug Administration approval for weight loss – could have fewer side effects. In clinical trials, 44% of those taking semaglutide had nausea and 31% reported diarrhea, compared with 33% and 23% of those taking tirzepatide, although no trial has directly compared the two agents. 
 

Loss of bowel control 

For now, Wegovy and Saxenda are the only GLP-1 agonist shots authorized for weight loss, and their maker, Danish drug company Novo Nordisk, is facing its second shortage of Wegovy amid growing demand. 

Personal stories online about semaglutide range from overwhelmingly positive – just what some need to win a lifelong battle with obesity – to harsh scenarios with potentially long-term health consequences, and everything in between. 

One private community on Reddit is dedicated to a particularly unpleasant side effect: loss of bowel control while sleeping. Others have reported uncontrollable vomiting.

Kimberly Carew of Clearwater, Fla., started on .5 milligrams of Ozempic last year after her rheumatologist and endocrinologist suggested it to treat her type 2 diabetes. She was told it came with the bonus of weight loss, which she was hoping would help with her joint and back pain. 

But after she increased the dose to 1 milligram, her GI symptoms, which started out mild, became unbearable. She couldn’t keep food down, and when she vomited, the food would often come up whole, she said. 

“One night I ate ramen before bed. And the next morning, it came out just as it went down,” said Ms. Carew, 42, a registered mental health counseling intern. “I was getting severe heartburn and could not take a couple bites of food without getting nauseous.”

She also had “sulfur burps,” a side effect discussed by some Ozempic users, causing her to taste rotten egg sometimes.

She was diagnosed with gastroparesis. Some types of gastroparesis can be resolved by discontinuing GLP-1 medications, as referenced in two case reports in the Journal of Investigative Medicine. 
 

Gut hormone

GI symptoms are most common with semaglutide because the hormone it imitates, GLP-1, is secreted by cells in the stomach, small intestines, and pancreas, said Anne Peters, MD, director of the USC Clinical Diabetes Programs.

“This is the deal: The side effects are real because it’s a gut hormone. It’s increasing the level of something your body already has,” she said. 

But, like Dr. Apovian, Dr. Peters said those side effects can likely be avoided if shots are started at the lowest doses and gradually adjusted up. 

While the average starting dose is .25 milligrams, Dr. Peters said she often starts her patients on about an eighth of that – just “a whiff of a dose.” 

“It’ll take them months to get up to the starting dose, but what’s the rush?” 

Dr. Peters said she also avoids giving diabetes patients the maximum dose, which is 2 milligrams per week for Ozempic (and 2.4 milligrams for Wegovy for weight loss). 

When asked about the drugs’ side effects, Novo Nordisk responded that “GLP-1 receptor agonists are a well-established class of medicines, which have demonstrated long-term safety in clinical trials. The most common adverse reactions, as with all GLP-1 [agonists], are gastrointestinal related.”
 

Is it the drug or the weight loss?

Still, non-gastrointestinal side effects such as hair loss, mood changes, and sunken facial features are reported among semaglutide users across the Internet. While these cases are often anecdotal, they can be very heartfelt.

Celina Horvath Myers, also known as CelinaSpookyBoo, a Canadian YouTuber who took Ozempic for type 2 diabetes, said she began having intense panic attacks and depression after starting the medication. 

“Who I have been these last couple weeks, has probably been the scariest time of my life,” she said on her YouTube channel. 

While severe depression and anxiety are not established side effects of the medication, some people get anhedonia, said W. Scott Butsch, MD, MSc, director of obesity medicine in the Bariatric and Metabolic Institute at Cleveland Clinic. But that could be a natural consequence of lower appetite, he said, given that food gives most people pleasure in the moment.

Many other reported changes come from the weight loss itself, not the medication, said Dr. Butsch.

“These are drugs that change the body’s weight regulatory system,” he said. “When someone loses weight, you get the shrinking of the fat cells, as well as the atrophy of the muscles. This rapid weight loss may give the appearance of one’s face changing.”

For some people, like Ms. Mendenall, the side effects are worth it. For others, like Ms. Carew, they’re intolerable. 

Ms. Carew said she stopped the medication after about 7 months, and gradually worked up to eating solid foods again. 

“It’s the American way, we’ve all got to be thin and beautiful,” she said. “But I feel like it’s very unsafe because we just don’t know how seriously our bodies will react to these things in the long term. People see it as a quick fix, but it comes with risks.”

Wegovy’s active ingredient, semaglutide, mimics the role of a natural hormone called glucagonlike peptide–1 (GLP-1), which helps you feel well fed. Semaglutide is used at a lower dose under the brand name Ozempic, which is approved for type 2 diabetes and used off-label for weight loss.  

Both Ozempic and Wegovy come with a warning label for potential side effects, the most common ones being nausea, diarrhea, stomach pain, and vomiting.

With the surging popularity of semaglutide, more people are getting prescriptions through telemedicine companies, forgoing more in-depth consultations, leading to more side effects, said Caroline Apovian, MD, professor of medicine at Harvard Medical School and codirector of the Center for Weight Management and Wellness at Brigham and Women’s Hospital, Boston.

Specialists say starting with low doses and gradually increasing over time helps avoid side effects, but insurance companies often require a faster timeline to continue covering the medication, Dr. Apovian said. 

“Insurance companies are practicing medicine for us by demanding the patient go up in dosage [too quickly],” she explained. 

Ms. Mendenall’s insurance has paid for her Wegovy shots, but without that coverage, she said it would cost her $1,200 per month. 

There are similar medications on the market, such as liraglutide, sold under the name Saxenda. But it is a daily, rather than a weekly, shot and also comes with side effects and has been shown to be less effective. In one clinical trial, the people being studied saw their average body weight over 68 weeks drop by 15.8% with semaglutide, and by 6.4% with liraglutide.

Tirzepatide, branded Mounjaro – a type 2 diabetes drug made by Eli Lilly that may soon gain Food and Drug Administration approval for weight loss – could have fewer side effects. In clinical trials, 44% of those taking semaglutide had nausea and 31% reported diarrhea, compared with 33% and 23% of those taking tirzepatide, although no trial has directly compared the two agents. 
 

Loss of bowel control 

For now, Wegovy and Saxenda are the only GLP-1 agonist shots authorized for weight loss, and their maker, Danish drug company Novo Nordisk, is facing its second shortage of Wegovy amid growing demand. 

Personal stories online about semaglutide range from overwhelmingly positive – just what some need to win a lifelong battle with obesity – to harsh scenarios with potentially long-term health consequences, and everything in between. 

One private community on Reddit is dedicated to a particularly unpleasant side effect: loss of bowel control while sleeping. Others have reported uncontrollable vomiting.

Kimberly Carew of Clearwater, Fla., started on .5 milligrams of Ozempic last year after her rheumatologist and endocrinologist suggested it to treat her type 2 diabetes. She was told it came with the bonus of weight loss, which she was hoping would help with her joint and back pain. 

But after she increased the dose to 1 milligram, her GI symptoms, which started out mild, became unbearable. She couldn’t keep food down, and when she vomited, the food would often come up whole, she said. 

“One night I ate ramen before bed. And the next morning, it came out just as it went down,” said Ms. Carew, 42, a registered mental health counseling intern. “I was getting severe heartburn and could not take a couple bites of food without getting nauseous.”

She also had “sulfur burps,” a side effect discussed by some Ozempic users, causing her to taste rotten egg sometimes.

She was diagnosed with gastroparesis. Some types of gastroparesis can be resolved by discontinuing GLP-1 medications, as referenced in two case reports in the Journal of Investigative Medicine. 
 

Gut hormone

GI symptoms are most common with semaglutide because the hormone it imitates, GLP-1, is secreted by cells in the stomach, small intestines, and pancreas, said Anne Peters, MD, director of the USC Clinical Diabetes Programs.

“This is the deal: The side effects are real because it’s a gut hormone. It’s increasing the level of something your body already has,” she said. 

But, like Dr. Apovian, Dr. Peters said those side effects can likely be avoided if shots are started at the lowest doses and gradually adjusted up. 

While the average starting dose is .25 milligrams, Dr. Peters said she often starts her patients on about an eighth of that – just “a whiff of a dose.” 

“It’ll take them months to get up to the starting dose, but what’s the rush?” 

Dr. Peters said she also avoids giving diabetes patients the maximum dose, which is 2 milligrams per week for Ozempic (and 2.4 milligrams for Wegovy for weight loss). 

When asked about the drugs’ side effects, Novo Nordisk responded that “GLP-1 receptor agonists are a well-established class of medicines, which have demonstrated long-term safety in clinical trials. The most common adverse reactions, as with all GLP-1 [agonists], are gastrointestinal related.”
 

Is it the drug or the weight loss?

Still, non-gastrointestinal side effects such as hair loss, mood changes, and sunken facial features are reported among semaglutide users across the Internet. While these cases are often anecdotal, they can be very heartfelt.

Celina Horvath Myers, also known as CelinaSpookyBoo, a Canadian YouTuber who took Ozempic for type 2 diabetes, said she began having intense panic attacks and depression after starting the medication. 

“Who I have been these last couple weeks, has probably been the scariest time of my life,” she said on her YouTube channel. 

While severe depression and anxiety are not established side effects of the medication, some people get anhedonia, said W. Scott Butsch, MD, MSc, director of obesity medicine in the Bariatric and Metabolic Institute at Cleveland Clinic. But that could be a natural consequence of lower appetite, he said, given that food gives most people pleasure in the moment.

Many other reported changes come from the weight loss itself, not the medication, said Dr. Butsch.

“These are drugs that change the body’s weight regulatory system,” he said. “When someone loses weight, you get the shrinking of the fat cells, as well as the atrophy of the muscles. This rapid weight loss may give the appearance of one’s face changing.”

For some people, like Ms. Mendenall, the side effects are worth it. For others, like Ms. Carew, they’re intolerable. 

Ms. Carew said she stopped the medication after about 7 months, and gradually worked up to eating solid foods again. 

“It’s the American way, we’ve all got to be thin and beautiful,” she said. “But I feel like it’s very unsafe because we just don’t know how seriously our bodies will react to these things in the long term. People see it as a quick fix, but it comes with risks.”

Medscape’s Editor-in-Chief Eric Topol, MD, referred to continual noninvasive, cuffless, accurate blood pressure devices as “a holy grail in sensor technology.”

He personally tested a cuff-calibrated, over-the-counter device available in Europe that claims to monitor daily blood pressure changes and produce data that can help physicians titrate medications.

Dr. Topol does not believe that it is ready for prime time. Yes, cuffless devices are easy to use, and generate lots of data. But are those data accurate?

Many experts say not yet, even as the market continues to grow and more devices are introduced and highlighted at high-profile consumer events.
 

Burned before

Limitations of cuffed devices are well known, including errors related to cuff size, patient positioning, patient habits or behaviors (for example, caffeine/nicotine use, acute meal digestion, full bladder, very recent physical activity) and clinicians’ failure to take accurate measurements.

But are the currently available cuffless devices acceptable substitutes?

Like many clinicians, Timothy B. Plante, MD, MHS, assistant professor at the University of Vermont Medical Center thrombosis & hemostasis program in Burlington, is very excited about cuffless technology. However, “we’ve been burned by it before,” he said in an interview.

Dr. Plante’s 2016 validation study of an instant blood pressure smartphone app found that its measurements were “highly inaccurate,” with such low sensitivity that more than three-quarters of individuals with hypertensive blood levels would be falsely reassured that their blood pressure was in the normal range.

His team’s 2023 review of the current landscape, which includes more sophisticated devices, concluded that accuracy remains an issue: “Unfortunately, the pace of regulation of these devices has failed to match the speed of innovation and direct availability to patient consumers. There is an urgent need to develop a consensus on standards by which cuffless BP devices can be tested for accuracy.”
 

Devices, indications differ

Cuffless devices estimate blood pressure indirectly. Most operate based on pulse wave analysis and pulse arrival time (PWA-PAT), explained Ramakrishna Mukkamala, PhD, in a commentary. Dr. Mukkamala is a professor in the departments of bioengineering and anesthesiology and perioperative medicine at the University of Pittsburgh.

PWA involves measuring a peripheral arterial waveform using an optical sensor such as the green lights on the back of a wrist-worn device, or a ‘force sensor’ such as a finger cuff or pressing on a smartphone. Certain features are extracted from the waveform using machine learning and calibrated to blood pressure values.

PAT techniques work together with PWA; they record the ECG and extract features from that signal as well as the arterial waveform for calibration to blood pressure values.

The algorithm used to generate the BP numbers comprises a proprietary baseline model that may include demographics and other patient characteristics. A cuff measurement is often part of the baseline model because most cuffless devices require periodic (typically weekly or monthly) calibration using a cuffed device.

Cuffless devices that require cuff calibration compare the estimate they get to the cuff-calibrated number. In this scenario, the cuffless device may come up with the same blood pressure numbers simply because the baseline model – which is made up of thousands of data points relevant to the patient – has not changed.

This has led some experts to question whether PWA-PAT cuffless device readings actually add anything to the baseline model.

They don’t, according to Microsoft Research in what Dr. Mukkamala and coauthors referred to (in a review published in Hypertension) as “a complex article describing perhaps the most important and highest resource project to date (Aurora Project) on assessing the accuracy of PWA and PWA devices.”

The Microsoft article was written for bioengineers. The review in Hypertension explains the project for clinicians, and concludes that, “Cuffless BP devices based on PWA and PWA-PAT, which are similar to some regulatory-cleared devices, were of no additional value in measuring auscultatory or 24-hour ambulatory cuff BP when compared with a baseline model in which BP was predicted without an actual measurement.”
 

IEEE and FDA validation

Despite these concerns, several cuffless devices using PWA and PAT have been cleared by the Food and Drug Administration.

Validating cuffless devices is no simple matter. The Institute of Electrical and Electronics Engineers published a validation protocol for cuffless blood pressure devices in 2014 that was amended in 2019 to include a requirement to evaluate performance in different positions and in the presence of motion with varying degrees of noise artifact.

However, Daichi Shimbo, MD, codirector of the Columbia Hypertension Center in New York and vice chair of the American Heart Association Statement on blood pressure monitoring, and colleagues point out limitations, even in the updated standard. These include not requiring evaluation for drift over time; lack of specific dynamic testing protocols for stressors such as exercise or environmental temperatures; and an unsuitable reference standard (oscillometric cuff-based devices) during movement.

Dr. Shimbo said in an interview that, although he is excited about them, “these cuffless devices are not aligned with regulatory bodies. If a device gives someone a wrong blood pressure, they might be diagnosed with hypertension when they don’t have it or might miss the fact that they’re hypertensive because they get a normal blood pressure reading. If there’s no yardstick by which you say these devices are good, what are we really doing – helping, or causing a problem?”

“The specifics of how a device estimates blood pressure can determine what testing is needed to ensure that it is providing accurate performance in the intended conditions of use,” Jeremy Kahn, an FDA press officer, said in an interview. “For example, for cuffless devices that are calibrated initially with a cuff-based blood pressure device, the cuffless device needs to specify the period over which it can provide accurate readings and have testing to demonstrate that it provides accurate results over that period of use.”

The FDA said its testing is different from what the Microsoft Aurora Project used in their study.

“The intent of that testing, as the agency understands it, is to evaluate whether the device is providing useful input based on the current physiology of the patient rather than relying on predetermined values based on calibration or patient attributes. We evaluate this clinically in two separate tests: an induced change in blood pressure test and tracking of natural blood pressure changes with longer term device use,” Mr. Kahn explained.

Analyzing a device’s performance on individuals who have had natural changes in blood pressure as compared to a calibration value or initial reading “can also help discern if the device is using physiological data from the patient to determine their blood pressure accurately,” he said.

Experts interviewed for this article who remain skeptical about cuffless BP monitoring question whether the numbers that appear during the induced blood pressure change, and with the natural blood pressure changes that may occur over time, accurately reflect a patient’s blood pressure.

“The FDA doesn’t approve these devices; they clear them,” Dr. Shimbo pointed out. “Clearing them means they can be sold to the general public in the U.S. It’s not a strong statement that they’re accurate.”
 

Moving toward validation, standards

Ultimately, cuffless BP monitors may require more than one validation protocol and standard, depending on their technology, how and where they will be used, and by whom.

And as Dr. Plante and colleagues write, “Importantly, validation should be performed in diverse and special populations, including pregnant women and individuals across a range of heart rates, skin tones, wrist sizes, common arrhythmias, and beta-blocker use.”

Organizations that might be expected to help move validation and standards forward have mostly remained silent. The American Medical Association’s US Blood Pressure Validated Device Listing website includes only cuffed devices, as does the website of the international scientific nonprofit STRIDE BP.

The European Society of Hypertension 2022 consensus statement on cuffless devices concluded that, until there is an internationally accepted accuracy standard and the devices have been tested in healthy people and those with suspected or diagnosed hypertension, “cuffless BP devices should not be used for the evaluation or management of hypertension in clinical practice.”

This month, ESH published recommendations for “specific, clinically meaningful, and pragmatic validation procedures for different types of intermittent cuffless devices” that will be presented at their upcoming annual meeting June 26.

Updated protocols from IEEE “are coming out soon,” according to Dr. Shimbo. The FDA says currently cleared devices won’t need to revalidate according to new standards unless the sponsor makes significant modifications in software algorithms, device hardware, or targeted patient populations.
 

Device makers take the initiative

In the face of conflicting reports on accuracy and lack of a robust standard, some device makers are publishing their own tests or encouraging validation by potential customers.

For example, institutions that are considering using the Biobeat cuffless blood pressure monitor watch “usually start with small pilots with our devices to do internal validation,” Lior Ben Shettrit, the company’s vice president of business development, said in an interview. “Only after they complete the internal validation are they willing to move forward to full implementation.”

Cardiologist Dean Nachman, MD, is leading validation studies of the Biobeat device at the Hadassah Ein Kerem Medical Center in Jerusalem. For the first validation, the team recruited 1,057 volunteers who did a single blood pressure measurement with the cuffless device and with a cuffed device.

“We found 96.3% agreement in identifying hypertension and an interclass correlation coefficient of 0.99 and 0.97 for systolic and diastolic measurements, respectively,” he said. “Then we took it to the next level and compared the device to ambulatory 24-hour blood pressure monitoring and found comparable measurements.”

The investigators are not done yet. “We need data from thousands of patients, with subgroups, to not have any concerns,” he says. “Right now, we are using the device as a general monitor – as an EKG plus heart rate plus oxygen saturation level monitor – and as a blood pressure monitor for 24-hour blood pressure monitoring.”

The developers of the Aktiia device, which is the one Dr. Topol tested, take a different perspective. “When somebody introduces a new technology that is disrupting something that has been in place for over 100 years, there will always be some grumblings, ruffling of feathers, people saying it’s not ready, it’s not ready, it’s not ready,” Aktiia’s chief medical officer Jay Shah, MD, noted.

“But a lot of those comments are coming from the isolation of an ivory tower,” he said.

Aktiia cofounder and chief technology officer Josep Solà said that “no device is probably as accurate as if you have an invasive catheter,” adding that “we engage patients to look at their blood pressure day by day. … If each individual measurement of each of those patient is slightly less accurate than a cuff, who cares? We have 40 measurements per day on each patient. The accuracy and precision of each of those is good.”

Researchers from the George Institute for Global Health recently compared the Aktiia device to conventional ambulatory monitoring in 41 patients and found that “it did not accurately track night-time BP decline and results suggested it was unable to track medication-induced BP changes.”

“In the context of 24/7 monitoring of hypertensive patients,” Mr. Solà said, “whatever you do, if it’s better than a sham device or a baseline model and you track the blood pressure changes, it’s a hundred times much better than doing nothing.”

Dr. Nachman and Dr. Plante reported no relevant financial relationships. Dr. Shimbo reported that he received funding from NIH and has consulted for Abbott Vascular, Edward Lifesciences, Medtronic, and Tryton Medical.

“The specifics of how a device estimates blood pressure can determine what testing is needed to ensure that it is providing accurate performance in the intended conditions of use,” Jeremy Kahn, an FDA press officer, said in an interview. “For example, for cuffless devices that are calibrated initially with a cuff-based blood pressure device, the cuffless device needs to specify the period over which it can provide accurate readings and have testing to demonstrate that it provides accurate results over that period of use.”

The FDA said its testing is different from what the Microsoft Aurora Project used in their study.

“The intent of that testing, as the agency understands it, is to evaluate whether the device is providing useful input based on the current physiology of the patient rather than relying on predetermined values based on calibration or patient attributes. We evaluate this clinically in two separate tests: an induced change in blood pressure test and tracking of natural blood pressure changes with longer term device use,” Mr. Kahn explained.

Analyzing a device’s performance on individuals who have had natural changes in blood pressure as compared to a calibration value or initial reading “can also help discern if the device is using physiological data from the patient to determine their blood pressure accurately,” he said.

Experts interviewed for this article who remain skeptical about cuffless BP monitoring question whether the numbers that appear during the induced blood pressure change, and with the natural blood pressure changes that may occur over time, accurately reflect a patient’s blood pressure.

“The FDA doesn’t approve these devices; they clear them,” Dr. Shimbo pointed out. “Clearing them means they can be sold to the general public in the U.S. It’s not a strong statement that they’re accurate.”
 

Moving toward validation, standards

Ultimately, cuffless BP monitors may require more than one validation protocol and standard, depending on their technology, how and where they will be used, and by whom.

And as Dr. Plante and colleagues write, “Importantly, validation should be performed in diverse and special populations, including pregnant women and individuals across a range of heart rates, skin tones, wrist sizes, common arrhythmias, and beta-blocker use.”

Organizations that might be expected to help move validation and standards forward have mostly remained silent. The American Medical Association’s US Blood Pressure Validated Device Listing website includes only cuffed devices, as does the website of the international scientific nonprofit STRIDE BP.

The European Society of Hypertension 2022 consensus statement on cuffless devices concluded that, until there is an internationally accepted accuracy standard and the devices have been tested in healthy people and those with suspected or diagnosed hypertension, “cuffless BP devices should not be used for the evaluation or management of hypertension in clinical practice.”

This month, ESH published recommendations for “specific, clinically meaningful, and pragmatic validation procedures for different types of intermittent cuffless devices” that will be presented at their upcoming annual meeting June 26.

Updated protocols from IEEE “are coming out soon,” according to Dr. Shimbo. The FDA says currently cleared devices won’t need to revalidate according to new standards unless the sponsor makes significant modifications in software algorithms, device hardware, or targeted patient populations.
 

Device makers take the initiative

In the face of conflicting reports on accuracy and lack of a robust standard, some device makers are publishing their own tests or encouraging validation by potential customers.

For example, institutions that are considering using the Biobeat cuffless blood pressure monitor watch “usually start with small pilots with our devices to do internal validation,” Lior Ben Shettrit, the company’s vice president of business development, said in an interview. “Only after they complete the internal validation are they willing to move forward to full implementation.”

Cardiologist Dean Nachman, MD, is leading validation studies of the Biobeat device at the Hadassah Ein Kerem Medical Center in Jerusalem. For the first validation, the team recruited 1,057 volunteers who did a single blood pressure measurement with the cuffless device and with a cuffed device.

“We found 96.3% agreement in identifying hypertension and an interclass correlation coefficient of 0.99 and 0.97 for systolic and diastolic measurements, respectively,” he said. “Then we took it to the next level and compared the device to ambulatory 24-hour blood pressure monitoring and found comparable measurements.”

The investigators are not done yet. “We need data from thousands of patients, with subgroups, to not have any concerns,” he says. “Right now, we are using the device as a general monitor – as an EKG plus heart rate plus oxygen saturation level monitor – and as a blood pressure monitor for 24-hour blood pressure monitoring.”

The developers of the Aktiia device, which is the one Dr. Topol tested, take a different perspective. “When somebody introduces a new technology that is disrupting something that has been in place for over 100 years, there will always be some grumblings, ruffling of feathers, people saying it’s not ready, it’s not ready, it’s not ready,” Aktiia’s chief medical officer Jay Shah, MD, noted.

“But a lot of those comments are coming from the isolation of an ivory tower,” he said.

Aktiia cofounder and chief technology officer Josep Solà said that “no device is probably as accurate as if you have an invasive catheter,” adding that “we engage patients to look at their blood pressure day by day. … If each individual measurement of each of those patient is slightly less accurate than a cuff, who cares? We have 40 measurements per day on each patient. The accuracy and precision of each of those is good.”

Researchers from the George Institute for Global Health recently compared the Aktiia device to conventional ambulatory monitoring in 41 patients and found that “it did not accurately track night-time BP decline and results suggested it was unable to track medication-induced BP changes.”

“In the context of 24/7 monitoring of hypertensive patients,” Mr. Solà said, “whatever you do, if it’s better than a sham device or a baseline model and you track the blood pressure changes, it’s a hundred times much better than doing nothing.”

Dr. Nachman and Dr. Plante reported no relevant financial relationships. Dr. Shimbo reported that he received funding from NIH and has consulted for Abbott Vascular, Edward Lifesciences, Medtronic, and Tryton Medical.

The introduction of tumor necrosis factor (TNF) inhibitors in the late 1990s revolutionized treatment of rheumatic diseases, such as rheumatoid arthritis (RA) and psoriatic arthritis (PsA), providing patients with another treatment option when conventional therapies were ineffective. However, when these diseases don’t respond to anti-TNF therapy, it is still difficult to determine the next best course of action.

“One of the big challenges we have in treatment of psoriatic arthritis, and I would say rheumatoid arthritis was well, is how to handle patients who have failed their first biologic therapy,” Christopher T. Ritchlin, MD, MPH, professor of allergy, immunology, and rheumatology at the University of Rochester (N.Y.), told this news organization. “In the case of both RA and PsA, that’s quite frequently an anti-TNF agent.”

For an estimated 30% to 40% of patients, TNF inhibitor therapy is discontinued because of nonresponse or intolerance. Clinicians can switch to another biologic or targeted synthetic disease-modifying antirheumatic drug (DMARD) or add another conventional DMARD, such as methotrexate. Now, several case studies as well as promising findings from phase 2 clinical trials suggest that combining two biologics could be an alternative strategy to improve patient response to treatment. However, concerns about safety and higher costs remain.
 

Targeting multiple mechanisms of action

Rheumatic conditions affect multiple areas of the body and involve different signaling pathways, said Dr. Ritchlin, who heads the Clinical Immunology Research Unit at the University of Rochester. PsA, for example, affects the skin, peripheral joints, the axial skeleton, and the entheses.

“The question is, Are these various manifestations – of which multiple [ones] are often seen in one patient – likely to respond to one therapy that targets one single pathway?” he said.

Combination therapies have been effective in treating leukemia and lymphoma as well as infection with HIV, Melek Yalçin Mutlu, MD, and colleagues from Friedrich Alexander University Erlangen-Nuremberg and the University Clinic Erlangen (Germany), wrote in a review about combining biologic DMARDs in the treatment of RA and PsA. The review was published in Joint Bone Spine.

“Cumulative evidence on the success of combination therapies in various diseases supports an akin approach in rheumatology, and simultaneous or sequential blockade of multiple mechanisms that generate or propagate arthritis could theoretically enhance efficacy,” the authors wrote. “On the other hand, intervening on multiple targets in the immune system brings about a risk of adverse events, among which infection is a major concern.”
 

Failed clinical trials

Clinical trials of combination biologic therapies for rheumatic disease have been tried before, but these combinations did not show superior efficacy, and they increased patients’ risk for infection. One study published in 2004 compared monotherapy with the TNF inhibitor etanercept (Enbrel) to the combination of etanercept and anakinra (Kineret), an interleukin-1 (IL-1) antagonist, in 244 patients with active RA despite methotrexate therapy. Researchers found no statistically significant difference in achieving 20% improvement in modified American College of Rheumatology response criteria (ACR20), ACR50, or ACR70 between the groups that received etanercept and anakinra and those that received etanercept alone. There were nine serious infections among patients given etanercept and anakinra, including one death due to pneumonia. There were no serious infections in the etanercept monotherapy group.

In another RA trial, 121 patients were given etanercept 25 mg twice weekly and were randomly assigned to also receive a placebo or low-dose abatacept (Orencia), a T-cell co-stimulation inhibitor. There was no significant difference in disease improvement between the two groups, although the rate of serious adverse events was nearly six times higher in the etanercept-abatacept group (16.5% vs. 2.8%).

These studies had a “chilling effect on the whole field for some years,” Brian G. Feagan, MD, the senior scientific director of the gastrointestinal contract research firm Alimentiv in London, Ontario, told this news organization. People were reluctant to try new biologic combinations, owing to the fear that these safety issues would plague subsequent trials.

Promising combinations

But a recent phase 2 trial, led by Dr. Feagan, suggests that certain combinations can be effective. In the Janssen-sponsored VEGA trial, researchers found that a combination of guselkumab (Tremfya), an IL-23 inhibitor, and golimumab (Simponi), an anti-TNF agent, was more effective than either drug used as monotherapy for initial induction treatment for moderate to severe ulcerative colitis. Importantly, there was no difference in adverse events between any of the groups. This same combination therapy is now being tried for patients with active PsA in Janssen’s AFFINITY trial, for which Dr. Ritchlin is one of the lead investigators.

Other trials have also delivered promising results. One study enrolled 51 adults with active RA who were all receiving stable doses of both a TNF inhibitor – either etanercept or adalimumab (Humira) – and methotrexate. Patients were randomly assigned to receive one course of rituximab (Rituxan) or placebo. The researchers found that the safety profile of this TNF inhibitor/methotrexate/rituximab combination was “consistent” with the safety profiles of previous studies of methotrexate/rituximab dual combinations with no TNF inhibitor; there were no new safety signals. At 24 weeks, 30% of the group that received rituximab reached ACR20, compared with 17% of the group that was given placebo. Twelve percent of the rituximab group achieved ACR50, compared with 6% of the group that received placebo.

“B-cell depletion is fundamentally different from cytokine inhibition and even from co-stimulation blockade, making an additive effect more likely,” Dr. Mutlu and colleagues wrote in their review. Reports have also suggested possible benefits of combining a TNF inhibitor and an IL-17 inhibitor in the treatment of RA and PsA, as well as the combination of a TNF inhibitor and an IL-23 antagonist for PsA.

While these combinations require controlled clinical trials, “there’s some smoke signals out there that this might be an effective strategy for some patients,” Dr. Ritchlin said.

In addition to the AFFINITY trial, two clinical trials are underway in France. The first, CRI-RA, is evaluating the combination of baricitinib (Olumiant), a Janus kinase (JAK) inhibitor, and adalimumab. Although baricitinib is not a biologic, as a targeted synthetic DMARD, the therapy is more potent than conventional DMARDs, and the same potential safety concerns apply. However, use of a combination of tofacitinib (Xeljanz) and different biologics for RA patients has been reported; no serious side effects were reported over 11 months of therapy. The randomized, placebo-controlled trial began in July 2021 and will enroll 178 patients. The estimated study completion date is July 2025.

“Of note, baricitinib does not directly block signaling downstream of TNF, even if an indirect effect on TNF production is likely to occur,” the CRI-RA entry on clinicaltrials.gov reads. “Targeting multiple inflammatory cytokines in combination may lead to more effective treatment and enhanced clinical responses in patients with RA compared to the current second-line strategies.”

The second trial, SEQUENS-RA, is evaluating the use of TNF inhibitors followed by abatacept for patients with RA who test positive for anticitrullinated protein autoantibodies (ACPAs). In the past, the combination of a TNF inhibitor and abatacept did not lead to promising results, but in this trial, the drugs will be administered sequentially.

“Although abatacept has shown a very good tolerance profile that might be superior to other bDMARDs [biologic DMARDs], rheumatologists might be reluctant to use it as a first line bDMARD as there is a belief of a slower efficacy compared to other bDMARDs or JAK inhibitors,” according to the clinical trial’s description. “Investigators have hypothesized that first rapidly controlling the inflammation phase, using TNF inhibitors, followed by abatacept to induce an immunological remission, would optimize response and tolerance of ACPA-positive patients with RA.”

The randomized trial of 220 participants began in November 2022. The estimated completion date for the study is November 2025.
 

Finding the right patients

Though these studies have had some promising results, the difference in efficacy between biologic monotherapy and dual therapy has been mostly moderate, Dr. Mutlu and coauthors wrote. Identifying disease subtypes for which there might be a higher likelihood of response to dual biologic treatment, especially multidrug-resistant types, could improve efficacies in future trials, they argued. “The good effects of bDMARD combinations in resistant patients in fact point into this direction, though they were observed in uncontrolled studies,” the authors noted.

Insurance coverage remains a “huge challenge” for these dual therapies because of the higher expense, noted Dr. Ritchlin. Better targeting therapies could help convince these companies to pay for these therapies.

“I would say that if we were able to demonstrate a phenotype of a patient that would respond to biologics and not monotherapies, [then] many companies would be amenable to this kind of approach,” he said.

Shortages of carboplatin and cisplatin have become widespread among major cancer centers, according to a survey released this week from the National Comprehensive Cancer Network.

The survey, which included responses from 27 NCCN member institutions, revealed that 93% are experiencing a shortage of carboplatin and that 70% have reported a shortage of cisplatin.

“This is an unacceptable situation,” Robert W. Carlson, MD, NCCN’s chief executive offer, said in the statement released by the network.

“We are hearing from oncologists and pharmacists across the country who have to scramble to find appropriate alternatives for treating their patients with cancer right now,” Dr. Carlson said. And while the survey results show patients are still able to get lifesaving care, “it comes at a burden to our overtaxed medical facilities.”

The NCCN called on the federal government, the pharmaceutical industry, providers, and payers to take steps to “help mitigate any impacts” from this cancer drug shortage.

“We need to work together to improve the current situation and prevent it from happening again in the future,” Dr. Carlson stressed.

Carboplatin and cisplatin, which are frequently used together for systemic treatment, are highly effective therapies prescribed to treat many cancer types, including lung, breast, and prostate cancers, as well as leukemias and lymphomas. An estimated 500,000 new patients with cancer receive these agents each year.

The current survey, conducted over the last week of May, found that 100% of responding centers are able to continue to treat patients who need cisplatin without delays.

The same cannot be said for carboplatin: only 64% of centers said they are still able to continue treating all current patients receiving the platinum-based therapy. Among 19 responding centers, 20% reported that they were continuing carboplatin regimens for some but not all patients. And 16% reported treatment delays from having to obtain prior authorization for modified treatment plans, though none reported denials.

“Carboplatin has been in short supply for months but in the last 4 weeks has reached a critical stage,” according to one survey comment. “Without additional inventory many of our sites will be out of drug by early next week.”

In response to the survey question, “Is your center experiencing a shortage of carboplatin,” others made similar comments:

• “Current shipments from established manufacturers have been paused.”
• “The supply of carboplatin available is not meeting our demands.”
• “Without additional supply in early June, we will have to implement several shortage mitigation strategies.”

Survey respondents also addressed whether manufacturers or suppliers have provided any indication of when these drugs will become readily available again. For both drugs, about 60% of respondents said no. And for those who do receive updates, many noted that the “information is tentative and variable.”

Respondents indicated that other cancer agents, including methotrexate (67%) and 5FU (26%), are also in short supply at their centers.

The shortage and the uncertainty as to when it will end are forcing some centers to develop conservation and mitigation strategies.

The NCCN has broadly outlined how the federal government, the pharmaceutical industry, providers, and payers can help with prevention and mitigation. The NCCN has called on the federal government and the pharmaceutical industry to work to secure a steady supply of core anticancer drugs and has asked payers to “put patients first and provide flexible and efficient systems of providing coverage for alternative therapies replacing anti-cancer drugs that are unavailable or in shortage.”

Overall, the survey results “demonstrate the widespread impact of the chemotherapy shortage,” said Alyssa Schatz, MSW, senior director of policy and advocacy for NCCN. “We hope that by sharing this survey and calling for united action across the oncology community, we can come together to prevent future drug shortages and ensure quality, effective, equitable, and accessible cancer care for all.”

Shortages of carboplatin and cisplatin have become widespread among major cancer centers, according to a survey released this week from the National Comprehensive Cancer Network.
