A new study provides more evidence that the substantial weight loss achieved with bariatric surgery offers long-term protection against cancer.

The study found that adults with obesity who had bariatric surgery had a 32% lower risk of developing cancer and a 48% lower risk of dying from cancer, compared with peers who did not have the surgery.

“The magnitude of the benefit was very large and dose-dependent, with more weight loss associated with greater reduction in cancer risk,” lead investigator Ali Aminian, MD, director of the Bariatric & Metabolic Institute, Cleveland Clinic, told this news organization.

The study was published online in the Journal of the American Medical Association.
 

Best evidence to date

“We know that obesity is strongly linked with different types of cancers, but we didn’t know if losing a significant amount of weight can significantly decrease the risk of cancer,” Dr. Aminian explained.

The SPLENDID study involved 30,318 adults with obesity (median age, 46 years; 77% women; median body mass index, 45 kg/m²). 

The 5,053 patients who underwent Roux-en-Y gastric bypass (66%) or sleeve gastrectomy (34%) were matched (1:5) to 25,265 patients who did not undergo bariatric surgery (nonsurgical control group).

At 10 years, patients who had bariatric surgery had lost 27.5 kg (60 pounds) compared with 2.7 kg (6 pounds) for peers who didn’t have the surgery, a difference of 19.2%. 

During a median follow-up of 6.1 years, 96 patients in the bariatric surgery group and 780 patients in the nonsurgical control group developed an obesity-associated cancer (incidence rate of 3.0 vs. 4.6 events per 1,000 person-years).

At 10 years, the cumulative incidence of obesity-associated cancer was significantly lower in the bariatric surgery group (2.9% vs. 4.9%; absolute risk difference, 2.0%; 95% confidence interval [CI], 1.2%-2.7%; adjusted hazard ratio [HR], 0.68; 95% CI, 0.53-0.87; P = .002).

Most cancer types were less common in the bariatric surgery group. However, a comprehensive analysis of the impact of bariatric surgery on individual cancer types was not possible.

In the fully-adjusted Cox models, the association between bariatric surgery and individual cancer types was significant only for endometrial cancer (adjusted HR, 0.47; 95% CI, 0.27-0.83). 

For the other individual cancers, there was a “trend or signal toward a reduction in their risk after the surgery,” Dr. Aminian said.

He noted that endometrial cancer has the strongest association with obesity, and patients who seek bariatric surgery are typically obese, middle-aged women.

“So, it was not surprising that we had more cases of endometrial cancer than other types of cancer,” he said.

The SPLENDID study also showed a significant reduction in cancer-related mortality at 10 years in patients with vs. without bariatric surgery (0.8% vs. 1.4%; adjusted HR, 0.52; 95% CI, 0.31-0.88; P = .01).

The benefits of bariatric surgery were evident in both women and men, younger and older patients, and Black and White patients, and were similarly observed after both gastric bypass and sleeve gastrectomy.

For the cancer protective effect, patients need to lose at least 20%-25% of their body weight, which is almost impossible with diet alone, Dr. Aminian said.

Obesity is “second only to tobacco” as a preventable cause of cancer in the United States, senior author Steven Nissen, MD, chief academic officer of the Heart, Vascular, and Thoracic Institute at Cleveland Clinic, said in a news release.

“This study provides the best possible evidence on the value of intentional weight loss to reduce cancer risk and mortality,” Dr. Nissen said.
 

Questions remain

In an accompanying editorial, Anita P. Courcoulas, MD, of the University of Pittsburgh Medical Center, said future studies should look at potential factors that influence the association between bariatric surgery and reduced cancer risk, with an eye toward individualizing treatment and figuring out who will benefit the most.

“It is likely that cancer risk reduction after bariatric surgery varies by sex, age, race and ethnicity, type of bariatric surgery, alcohol and smoking status, cancer site, diabetes status, body mass index, and other factors,” Dr. Courcoulas pointed out.

“In addition, there is a need to understand the specific biological mechanisms of effect responsible for the observed change in cancer risk because these mechanisms have not been clearly investigated and elucidated in humans,” she said.

“If this association is further validated, it would extend the benefits of bariatric surgery to another important area of long-term health and prevention. This additional information could then further guide for whom bariatric surgery is most beneficial,” Dr. Courcoulas concluded.

The study had no specific funding. Dr. Aminian reported receiving grants and speaking honoraria from Medtronic. Dr. Nissen reported receiving grants from Novartis, Eli Lilly, AbbVie, Silence Therapeutics, AstraZeneca, Esperion Therapeutics, Amgen, and Bristol Myers Squibb. A complete list of author disclosures is available with the original article.  Dr. Courcoulas had no relevant disclosures.

Kendra Joseph of San Antonio, Tex., had given up on the idea of having a second child. At 40 years old, and with a daughter pleading for a sibling, she and her husband were nervous about the risk of trying for another child due to her advanced maternal age. Mrs. Joseph had ended an earlier pregnancy at 15 weeks after finding out her son had Edwards syndrome, a genetic trait that’s fatal in most cases.

Now a new Texas law that bans abortion past 6 weeks would mean that if either she or her baby were at risk of dying, she might still have to carry the baby to term. For Mrs. Joseph, it wasn’t worth the risk at first. Then in February, just as they had decided against another baby, the couple found out they were expecting. She’s thrilled about her pregnancy, but it’s also been a nervewracking few months.

“It’s scary being pregnant anyway,” she says, “but these new restrictions add a layer of stress.”

Twenty-eight states could ban or tightly restrict abortion if the Supreme Court overturns the landmark Roe v. Wade decision. A leaked draft of the court’s opinion has been widely interpreted as signaling that the court will overturn the law. This means that women who are at a higher risk of pregnancy complications or those who have chronic conditions before getting pregnant could be at risk of dying if they can’t get an abortion.

According to the CDC, the maternal mortality rate in the United States in 2020 was 23.8 deaths per 100,000 live births – among the highest in the developed world. The rate is eight times as high as it is in countries like the Netherlands, Norway, and New Zealand.

“Many of the women I take care of have a pregnancy that presents a real and present danger to their health, and this often goes along with the fact that they’re very unlikely to have a healthy baby,” says Chavi Karkowsky, MD, a maternal fetal medicine specialist at Montefiore Medical Center, New York.

Maternal mortality, she says, can be caused by health conditions that some women may not know about before getting pregnant. (For example, finding out she had cervical cancer at a prenatal visit and then having to choose between chemotherapy and her baby.) And there are also life-threatening conditions caused by pregnancy, like preeclampsia, which can cause high blood pressure and kidney damage, as well as gestational diabetes. Research has also shown that the risk of maternal mortality increases with age.

University of Colorado researchers, in a study published in the journal Demography, found that banning abortion nationwide would lead to a 20% increase in maternal death. For Black women, the increase in mortality could be as high as 33%, due to higher rates of poverty and less access to health care, says Amanda Stevenson, PhD, a sociologist at the University of Colorado and one of the study’s authors. Black women in the U.S. are more than three times as likely to die as a result of pregnancy complications due to poor exposure to health care, structural racism, and chronic health conditions, according to the CDC.

If Roe v. Wade is overturned, more women will likely die because remaining pregnant poses a far greater mortality risk for them than the risk associated with an abortion, says Dr. Stevenson.

For women with high-risk pregnancies who need an abortion, traveling out of state puts them at a health risk, says Jamila Perritt, MD, an ob.gyn. in Washington, D.C. and president of Physicians for Reproductive Health. In places where abortion is restricted, it can cause significant delays in accessing medical care. “Abortion is a time-sensitive procedure, and as the pregnancy progresses, it can become increasingly difficult to find a clinic that will provide care,” she says.

She recalls one of her patients who had a heart problem that required a pregnancy to be ended. The patient at first had to travel to find a doctor who could evaluate her unique condition, then go out of state to get an abortion. All the while, the clock was ticking and her health was at risk. In this case, the patient had the money to travel out of state, find child care, and pay for the procedure.

“This was a resourced individual, and while this was difficult for her, it wasn’t impossible,” says Dr. Perritt.

Many of the states with the highest maternal mortality rates, including Louisiana, Texas, Arkansas, Alabama, South Carolina, and Georgia, also plan to strictly limit abortions or ban them completely. Some abortion opponents insist this won’t harm mothers.

“The pro-life movement loves both babies and moms,” says Sarah Zagorski, a spokeswoman for Louisiana Right to Life. “It is a tragedy that Louisiana has high mortality rates among pregnant women. However, legal abortion does not improve these rates.”

But for many women who need an abortion, statewide bans may make it hard to get. This worries Kendra Joseph, who’s now 18 weeks into her pregnancy.

“I try to put the bad things that could happen out of my mind, but it’s really hard when you’re dealing with these totally unnecessary and cruel restrictions. We as women, we’re just losing so much,” she says.

The U.S. Food and Drug Administration has declined to take further action against a group of investigators at Hennepin County Medical Center/Hennepin Healthcare (HCMC) who conducted controversial studies involving ketamine and other sedatives on agitated persons without their consent.

A citizen petition filed by Public Citizen, a consumer advocacy group, had asked the FDA to initiate clinical-investigator disqualification proceedings against Jon Cole, MD, and Lauren Klein, MD, along with other researchers who participated in the studies, for “repeatedly and deliberately initiating and conducting clinical investigations of investigational drug products” without having submitted or having in effect the investigational new drug applications (INDs) required by the FDA.

In certain situations, wherein the FDA alleges that a clinical investigator has violated applicable regulations, the agency may initiate clinical investigator disqualification proceedings. The names of the disqualified researchers are then added to a federal database.

The petition, which was filed in November 2021, also requested that the FDA initiate disqualification proceedings against the institutional review board (IRB) at HCMC for repeatedly failing to comply with federal regulations that adversely affected the rights and welfare of the individuals who were enrolled in the study without their consent.

Of note, Public Citizen stated that the FDA should have required the hospital to contact the more than 1,700 patients who “were unwittingly enrolled in unethical experiments” and inform them that their rights had been violated and their health potentially endangered by the research team.

Michael A. Carome, MD, director of Public Citizen’s Health Research Group, told this news organization that it is uncommon for the FDA to disqualify researchers. “It should be more common than it is,” he said. “I think that FDA is just reluctant to take more action.”

The actions of the Hennepin investigators were “repetitive and appeared to be in deliberate violation of regulations,” he added. “The case for the FDA disqualifying the HCMC researchers is overwhelming. The FDA’s slap-on-the-wrist approach to such appalling regulatory and ethical violations risks emboldening other researchers to disregard the rights and welfare of human subjects.”

Carl Elliott, MD, PhD, a bioethicist at the University of Minnesota, Minneapolis, agrees that the researcher from HCMC should be disqualified. “They didn’t just conduct risky, exploitative studies – they conducted them after the FDA had warned them not to proceed,” he said. “The message sent by this slap on the wrist is that investigators can do whatever they want to nonconsenting subjects, and the FDA will look the other way.”
 

Initial complaint

Public Citizen initially filed a complaint with the FDA in 2018, after learning that researchers affiliated with HCMC were conducting high-risk clinical trials involving ketamine to control agitation outside of the hospital setting. The complaint was cosigned by 64 doctors, bioethicists, and academic researchers and was also submitted to the Office for Human Research Protections.

The FDA typically allows investigational drugs to be used in emergency situation without obtaining informed consent if the therapies are known to carry a minimal risk. The IRB at HCMC had determined that this was the case with ketamine and approved the trials.

But according to Public Citizen’s complaint, prior research had suggested that ketamine could cause more complications and severe adverse events, compared with other sedatives.

The trials were conducted between 2014 and 2018, and in its letter, Public Citizen alleged that the investigators and the IRB had allowed these trials to proceed without obtaining informed consent from patients. The goal was to evaluate how well ketamine worked, compared with other drugs in calming agitated individuals: “The patients were given either ketamine or haloperidol for agitation by paramedics who responded to medical emergencies, and the goal was to see which drug worked faster,” said Dr. Carome. “Patients were only notified afterwards that they had received a sedative. Informed consent had been waived by IRB.”

In the first clinical trial conducted by HCMC, published in 2016, the researchers had hypothesized that 5 mg/kg of intramuscular ketamine would be superior to 10 mg of intramuscular haloperidol for severe prehospital agitation. Time to adequate sedation was the primary outcome measure. The study included 146 people; 64 received ketamine and 82 received haloperidol. They found that ketamine worked far more quickly than haloperidol (5 minutes vs. 17 minutes) but that the risk for complications was much higher. Complications occurred in 49% of patients receiving ketamine, compared with 5%.

“There was a 10-fold risk of adverse events,” said Dr. Carome. “And 39% of patients given ketamine had respiratory problems requiring intubation, compared to 4% who received haloperidol.”

A second study was launched in 2017, wherein ketamine was compared with midazolam in agitated patients. During the first 6-month period of the study, individuals would receive a ketamine-based protocol for prehospital agitation, and during the second 6 months, that would switch to midazolam. However, the study was halted in June 2018 after the local newspaper, the Star Tribune, reported that the city police had encouraged medical personnel to sedate agitated patients. This included individuals who had already been physically restrained.

The report stated that “in many cases, the individual being detained or arrested was not only handcuffed but strapped down on a stretcher in an ambulance before receiving ketamine,” and that it raised a “concerning question” over why these people were given the drug before they were transported to the hospital, “given the immediate effects on breathing and heart function that the drug induces.”

Along with halting the trial, HCMC asked for a review of cases involving its paramedics; an independent investigation led by former U.S. Deputy Attorney General Sally Yates was initiated to assess whether the Minneapolis police had crossed a line and urged paramedics to use ketamine.

“The decision to use ketamine was based on the study’s timeline and not on clinical judgment,” said Dr. Carome.

The FDA acknowledged receipt of the complaint and inspected the IRB records and the clinical trial data. Preliminary reports received by Public Citizen confirmed their allegations. “There were not appropriate protections for vulnerable subjects,” he said. “In 2019, the FDA did further investigations, and those reports had similar findings.”
 

FDA letters

The FDA had sent warning letters to Dr. Cole and Dr. Klein, citing them for ignoring federal safety laws in experimental research on the public. In their investigations, the FDA cited “objectionable conditions” for the studies led by Dr. Cole and Dr. Klein, according to the letters. Both researchers seemingly ignored FDA regulations and used practices that subjected patients to “significantly increased risk,” and the hospital defended its research with “factually incorrect” statements.

In a letter to Dr. Cole, the FDA noted that he never filed INDs for the trials with the FDA, as required by law, and that he also failed to write appropriate protocols to ensure that children and pregnant women were not enrolled in the research. Individuals under the influence of intoxicants also were not excluded, though the use of ketamine is cautioned in this population.

“Administration of the investigational drugs to these subjects placed them at significantly increased risk of the adverse events associated with the investigational products and decreased the acceptability of those risks,” the FDA said in its letter. “Your failure to exclude, and the lack of any precautions for, subjects under the influence of various intoxicants significantly increased the risks and/or decreased the acceptability of the risks associated with the investigational drugs.”

However, Dr. Cole conducted both studies in the prehospital setting and failed to initiate any specific measures to protect study participants, according to the FDA.
 

Petition denied

Dr. Carome noted that the researchers had committed repetitive egregious regulatory violations over a 4-year period, which were documented by the FDA in their warning letters to Dr. Cole and Dr. Klein. “We felt that they were so egregious that we need to send a signal to the community that this sort of behavior will not be tolerated,” he said. “The FDA denied our petition, and we think that sends the wrong signal to the research community.”

In their response, the FDA noted that as with judicial enforcement, “the Agency makes decisions regarding whether to pursue administrative enforcement action, including disqualification proceedings, on a case-by-case basis, considering all relevant facts and circumstances.” They added that at this time, they would not be taking further action against Dr. Cole and Dr. Klein.

“However, we intend to continue to consider all the options available to the Agency as we determine whether to pursue additional compliance actions related to this matter,” the FDA concluded.

The FDA declined to comment further on their decision.

Dr. Cole also declined to comment, but Hennepin Healthcare told this news organization that the “decision by the FDA to deny the petition validates the changes we made to strengthen and improve the clinical research program across the institution since the closing of the studies in 2018. We look forward to continuing to work with the FDA to ensure full compliance with the standards in place to protect research subjects.”

The U.S. Food and Drug Administration has declined to take further action against a group of investigators at Hennepin County Medical Center/Hennepin Healthcare (HCMC) who conducted controversial studies involving ketamine and other sedatives on agitated persons without their consent.

A citizen petition filed by Public Citizen, a consumer advocacy group, had asked the FDA to initiate clinical-investigator disqualification proceedings against Jon Cole, MD, and Lauren Klein, MD, along with other researchers who participated in the studies, for “repeatedly and deliberately initiating and conducting clinical investigations of investigational drug products” without having submitted or having in effect the investigational new drug applications (INDs) required by the FDA.

In certain situations, wherein the FDA alleges that a clinical investigator has violated applicable regulations, the agency may initiate clinical investigator disqualification proceedings. The names of the disqualified researchers are then added to a federal database.

The petition, which was filed in November 2021, also requested that the FDA initiate disqualification proceedings against the institutional review board (IRB) at HCMC for repeatedly failing to comply with federal regulations that adversely affected the rights and welfare of the individuals who were enrolled in the study without their consent.

Of note, Public Citizen stated that the FDA should have required the hospital to contact the more than 1,700 patients who “were unwittingly enrolled in unethical experiments” and inform them that their rights had been violated and their health potentially endangered by the research team.

Michael A. Carome, MD, director of Public Citizen’s Health Research Group, told this news organization that it is uncommon for the FDA to disqualify researchers. “It should be more common than it is,” he said. “I think that FDA is just reluctant to take more action.”

The actions of the Hennepin investigators were “repetitive and appeared to be in deliberate violation of regulations,” he added. “The case for the FDA disqualifying the HCMC researchers is overwhelming. The FDA’s slap-on-the-wrist approach to such appalling regulatory and ethical violations risks emboldening other researchers to disregard the rights and welfare of human subjects.”

Carl Elliott, MD, PhD, a bioethicist at the University of Minnesota, Minneapolis, agrees that the researcher from HCMC should be disqualified. “They didn’t just conduct risky, exploitative studies – they conducted them after the FDA had warned them not to proceed,” he said. “The message sent by this slap on the wrist is that investigators can do whatever they want to nonconsenting subjects, and the FDA will look the other way.”
 

Initial complaint

Public Citizen initially filed a complaint with the FDA in 2018, after learning that researchers affiliated with HCMC were conducting high-risk clinical trials involving ketamine to control agitation outside of the hospital setting. The complaint was cosigned by 64 doctors, bioethicists, and academic researchers and was also submitted to the Office for Human Research Protections.

The FDA typically allows investigational drugs to be used in emergency situation without obtaining informed consent if the therapies are known to carry a minimal risk. The IRB at HCMC had determined that this was the case with ketamine and approved the trials.

But according to Public Citizen’s complaint, prior research had suggested that ketamine could cause more complications and severe adverse events, compared with other sedatives.

NEW ORLEANS – Obesity in adolescence is linked to an increased risk for type 1 diabetes onset in adulthood, new research suggests.

These new data, from Israeli military recruits followed for over a decade, suggest that obesity may be playing a causal role in type 1 as well as type 2 diabetes.

The incidence of type 1 diabetes has been increasing by about 2%-3% annually over recent decades, but the reasons aren’t clear. The study is the first to examine the role of obesity in adolescence and type 1 diabetes in young adulthood, and also the first to examine the question of using antibody status as part of the criteria for a type 1 diagnosis.

The findings were reported at the annual scientific sessions of the American Diabetes Association by Gilad Twig, MD, PhD, professor of medicine at Sheba Medical Center, Tel HaShomer, Israel. “For people who might have a high risk for developing type 1 diabetes, these results emphasize the importance of maintaining a normal weight,” he said in an interview. He noted that, although this recommendation applies to everyone, “here it’s becoming more precise for the population – more individualized in the sense that this might specifically help you.”

Naveed Sattar, PhD, professor and honorary consultant in cardiovascular and medical sciences at the University of Glasgow, said in an interview that carrying too much weight “will make the pancreas have to work harder to make insulin to keep the sugar normal. So, if you’re stressing the system and the pancreas is already likely to fail, it will fail faster.”

Clinically, Dr. Sattar said, “Lifestyle does matter to the risk of developing type 1 diabetes. The weighting may be different [from type 2]. The major factor in type 1 is still the genetics, but if you have a family history of type 1 and your genetic potential is greater, you will minimize your risk by staying leaner.”
 

Study highlights that type 1 is not always ‘juvenile’

In addition to countering the long-held belief that type 1 diabetes is primarily a condition of thin individuals and unrelated to obesity, the data also reinforce the emerging recognition that type 1 diabetes isn’t always “juvenile” and in fact often arises in adulthood.

“About half of all cases of type 1 diabetes develop after age 18. By reputation, people think it’s a disease of children. But it’s begun to grow so that now 50% of cases occur after late adolescence,” noted Dr. Twig.

Dr. Sattar pointed to a UK Biobank study showing that nearly half of all cases of type 1 diabetes arise after age 30 years. “You absolutely can get type 1 in adulthood. It’s not rare.”
 

Direct correlation seen in otherwise healthy young people

The retrospective nationwide cohort study included 1,426,362 17-year-olds (834,050 male and 592,312 female) who underwent medical evaluation prior to military conscription starting in January 1996 and followed them through 2016. At baseline, none had a history of dysglycemia.

The data were linked with information about adult-onset type 1 diabetes in the Israeli National Diabetes Registry. In all, 777 incident type 1 diabetes cases were recorded over the study period, with a rate of 4.9 cases per 100,000 person-years.

Over a median follow-up of 11.2 years, there was a graded incidence of type 1 diabetes across BMI groups from underweight to obesity, from 3.6 to 8.4 cases per 100,000 person-years.

After adjustment for sex, birth year, age at study entry, education, and cognitive performance with BMI 5th-49th percentiles as the reference, the hazard ratios were 1.05 for the 50th-74th BMI percentiles, 1.41 for 75th-84th, 1.54 for those who were overweight, and 2.05 for those with obesity.

Every 5-unit increment in BMI corresponded to a 35% greater incidence of type 1 diabetes (adjusted hazard ratio 1.35) and every one increment was associated with a 35% greater risk (1.25), both values significant.

Sensitivity analyses resulted in similar findings for those with no other chronic health conditions at baseline. The results also didn’t change in a separate analysis of 574,720 subjects in whom autoantibody data were available to confirm the type 1 diabetes diagnosis.
 

Hypotheses for mechanisms

The mechanism for the association isn’t clear, but in a simultaneously published article in Diabetologia, Dr. Twig and colleagues outline several hypotheses. One relates to the growing evidence of a link between various autoimmune conditions, which point to the possibility of elevated adipokines and cytokines in obesity diminishing self-tolerance by promoting proinflammatory processes.

The authors cite data from the TrialNet Pathway to Prevention study of relatives of people with type 1 diabetes in which participants who were overweight and obese had an increased risk of islet autoantibody expression. However, not all data have supported this finding.

“Obesity is related to several other autoimmune conditions, so it’s not a complete surprise it might be related to another,” Dr. Twig noted.

Other possibilities include vitamin D deficiency, a high-fat diet, and alterations in gut microbiota.

And then there’s the “accelerator hypothesis,” suggesting that both type 1 and type 2 diabetes result from insulin resistance and genetic background that affect the rate of beta cell loss and the disease phenotype. Dr. Sattar said that the accelerator hypotheses “makes complete sense to me. Because the population is so obese, we’re seeing it more now whereas we might not have seen it 40 years ago when the BMI differentials were far less in society.”

Dr. Twig has no disclosures. Dr. Sattar has consulted for or received lecture fees from Amgen, AstraZeneca, Boehringer Ingelheim, Eli Lilly, Hanmi Pharmaceutical, Merck Sharp & Dohme, Novartis, Novo Nordisk, Pfizer, and Sanofi, and received grant support from AstraZeneca, Boehringer Ingelheim, Novartis, and Roche Diagnostics through his institution.

NEW ORLEANS – Obesity in adolescence is linked to an increased risk for type 1 diabetes onset in adulthood, new research suggests.

These new data, from Israeli military recruits followed for over a decade, suggest that obesity may be playing a causal role in type 1 as well as type 2 diabetes.

The incidence of type 1 diabetes has been increasing by about 2%-3% annually over recent decades, but the reasons aren’t clear. The study is the first to examine the role of obesity in adolescence and type 1 diabetes in young adulthood, and also the first to examine the question of using antibody status as part of the criteria for a type 1 diagnosis.

The findings were reported at the annual scientific sessions of the American Diabetes Association by Gilad Twig, MD, PhD, professor of medicine at Sheba Medical Center, Tel HaShomer, Israel. “For people who might have a high risk for developing type 1 diabetes, these results emphasize the importance of maintaining a normal weight,” he said in an interview. He noted that, although this recommendation applies to everyone, “here it’s becoming more precise for the population – more individualized in the sense that this might specifically help you.”

Naveed Sattar, PhD, professor and honorary consultant in cardiovascular and medical sciences at the University of Glasgow, said in an interview that carrying too much weight “will make the pancreas have to work harder to make insulin to keep the sugar normal. So, if you’re stressing the system and the pancreas is already likely to fail, it will fail faster.”

Clinically, Dr. Sattar said, “Lifestyle does matter to the risk of developing type 1 diabetes. The weighting may be different [from type 2]. The major factor in type 1 is still the genetics, but if you have a family history of type 1 and your genetic potential is greater, you will minimize your risk by staying leaner.”
 

Study highlights that type 1 is not always ‘juvenile’

In addition to countering the long-held belief that type 1 diabetes is primarily a condition of thin individuals and unrelated to obesity, the data also reinforce the emerging recognition that type 1 diabetes isn’t always “juvenile” and in fact often arises in adulthood.

“About half of all cases of type 1 diabetes develop after age 18. By reputation, people think it’s a disease of children. But it’s begun to grow so that now 50% of cases occur after late adolescence,” noted Dr. Twig.

Dr. Sattar pointed to a UK Biobank study showing that nearly half of all cases of type 1 diabetes arise after age 30 years. “You absolutely can get type 1 in adulthood. It’s not rare.”
 

Direct correlation seen in otherwise healthy young people

The retrospective nationwide cohort study included 1,426,362 17-year-olds (834,050 male and 592,312 female) who underwent medical evaluation prior to military conscription starting in January 1996 and followed them through 2016. At baseline, none had a history of dysglycemia.

The data were linked with information about adult-onset type 1 diabetes in the Israeli National Diabetes Registry. In all, 777 incident type 1 diabetes cases were recorded over the study period, with a rate of 4.9 cases per 100,000 person-years.

Over a median follow-up of 11.2 years, there was a graded incidence of type 1 diabetes across BMI groups from underweight to obesity, from 3.6 to 8.4 cases per 100,000 person-years.

After adjustment for sex, birth year, age at study entry, education, and cognitive performance with BMI 5th-49th percentiles as the reference, the hazard ratios were 1.05 for the 50th-74th BMI percentiles, 1.41 for 75th-84th, 1.54 for those who were overweight, and 2.05 for those with obesity.

Every 5-unit increment in BMI corresponded to a 35% greater incidence of type 1 diabetes (adjusted hazard ratio 1.35) and every one increment was associated with a 35% greater risk (1.25), both values significant.

Sensitivity analyses resulted in similar findings for those with no other chronic health conditions at baseline. The results also didn’t change in a separate analysis of 574,720 subjects in whom autoantibody data were available to confirm the type 1 diabetes diagnosis.
 

Hypotheses for mechanisms

The mechanism for the association isn’t clear, but in a simultaneously published article in Diabetologia, Dr. Twig and colleagues outline several hypotheses. One relates to the growing evidence of a link between various autoimmune conditions, which point to the possibility of elevated adipokines and cytokines in obesity diminishing self-tolerance by promoting proinflammatory processes.

The authors cite data from the TrialNet Pathway to Prevention study of relatives of people with type 1 diabetes in which participants who were overweight and obese had an increased risk of islet autoantibody expression. However, not all data have supported this finding.

“Obesity is related to several other autoimmune conditions, so it’s not a complete surprise it might be related to another,” Dr. Twig noted.

Other possibilities include vitamin D deficiency, a high-fat diet, and alterations in gut microbiota.

And then there’s the “accelerator hypothesis,” suggesting that both type 1 and type 2 diabetes result from insulin resistance and genetic background that affect the rate of beta cell loss and the disease phenotype. Dr. Sattar said that the accelerator hypotheses “makes complete sense to me. Because the population is so obese, we’re seeing it more now whereas we might not have seen it 40 years ago when the BMI differentials were far less in society.”

Transgender and nonbinary adolescents are twice as likely to experience sexual violence as their cisgendered peers but are less likely to attempt rape or commit sexual assault, researchers have found.

The study, which was published online  in JAMA Network Open, is among the first on the sexual violence that trans, nonbinary, and other gender nonconforming adolescents experience. Previous studies have focused on adults.

“In the busy world of clinical care, it is essential that clinicians be aware of potential disparities their patients are navigating,” said Michele Ybarra, PhD, MPH, president and research director of the Center for Innovative Public Health Research, San Clemente, California, who led the study. “This includes sexual violence victimization for gender minority youth and the need to talk about consent and boundaries for youth of all genders.”

Dr. Ybarra said that while clinicians may be aware that transgender young people face stigma, discrimination, and bullying, they may not be aware that trans youth are also the targets of sexual violence.

Studies indicate that health care providers and communities have significant misconceptions about sexually explicit behavior among trans and nonbinary teens. Misconceptions can lead to discrimination, resulting in higher rates of drug abuse, dropping out of school, suicide, and homelessness.

Dr. Ybarra and her colleagues surveyed 911 trans, nonbinary, or questioning youth on Instagram and Facebook through a collaboration with Growing Up With Media, a national longitudinal survey designed to investigate sexual violence during adolescence.

They also surveyed 3,282 cisgender persons aged 14-16 years who were recruited to the study between June 2018 and March 2020. The term “cisgender” refers to youth who identify with their gender at birth.

The questionnaires asked teens about gender identity, race, economic status, and support systems at home. Factors associated with not experiencing sexual violence included having a strong network of friends, family, and educators; involvement in the community; and having people close who affirm their gender identity.

More than three-fourths (78%) of youth surveyed identified as cisgender, 13.9% identified as questioning, and 7.9% identified as transgender.

Roughly two-thirds (67%) of transgender adolescents said they had experienced serious sexual violence, 73% reported experiencing violence in their communities, and 63% said they had been exposed to aggressive behavior. In contrast, 6.7% of trans youth said they had ever committed sexual violence, while 7.4% of cisgender teens surveyed, or 243 students, said they had done so.

“The relative lack of visibility of gender minority youth in sexual violence research is unacceptable,” Dr. Ybarra told this news organization. “To be counted, one needs to be seen. We aimed to start addressing this exclusion with the current study.”

The findings provide a lens into the levels of sexual violence that LGBTQIA+ youth experience and an opportunity to provide more inclusive care, according to Elizabeth Miller, MD, PhD, FSAHM, Distinguished Professor of Pediatrics, director of the Division of Adolescent and Young Adult Medicine, and medical director of community and population health at UPMC Children’s Hospital of Pittsburgh, who was not involved in the study.

“There are unfortunately pervasive and harmful stereotypes in our society about the ‘sexual deviancy’ attributed to LGBTQIA+ individuals,” Dr. Miller told this news organization. “This study adds to the research literature that counters and challenges these harmful – and inaccurate – perceptions.”

Dr. Miller said clinicians can help this population by offering youth accurate information about relevant support and services, including how to help a friend.

Programs that providers could incorporate include gender transformative approaches, which guide youth to examine gender norms and inequities and that develop leadership skills.

Such programs are more common outside the United States and have been shown to decrease LGBTQIA+ youth exposure to sexual violence, she said.

Dr. Miller said more research is needed to understand the contexts in which gender minority youth experience sexual violence to guide prevention efforts: “We need to move beyond individual-focused interventions to considering community-level interventions to create safer and more inclusive spaces for all youth.”

Dr. Miller has received royalties for writing content for UptoDate Wolters Kluwer outside of the current study. Dr. Ybarra has disclosed no relevant financial relationships.

As increasing numbers of patients in their 80s, 90s, and even 100s present for possible Mohs micrographic surgery, surgeons are confronted with deciding when the risks of treatment may outweigh the benefits.

In one of two presentations at the annual meeting of the American College of Mohs Surgery that addressed this topic, Howard W. Rogers, MD, of Advanced Dermatology in Norwich, Conn., said that the crux of the issue is the concern not to undertreat. He noted that reduced access to dermatologic care during the pandemic has provided a stark lesson in the risks of delaying treatment in all age groups. “Mohs surgeons have all seen the consequences of delayed treatment due to the pandemic with enormous, destructive, and sometimes fatal cancers coming to the office in the last year,” he told this news organization.

“Pandemic-related treatment delay has caused increased suffering and morbidity for countless skin cancer patients across the U.S.,” he said. “In general, not treating skin cancer and hoping it’s not going to grow or having significant delays in treatment are a recipe for disastrous outcomes.”

That said, active monitoring may be appropriate “for select small cancers that tend to grow slowly in the very elderly,” added Dr. Rogers, the incoming ACMS president. Among the key situations where the benefits of active monitoring may outweigh the risks of surgery are small, slowly growing cancers, when frailty is an issue.

Frailty has been equated to compromised functionality, which can increase the risk of an array of complications, including prolonged wound healing and secondary complications stemming from immobility. The toll those issues can take on patients’ quality of life can be considerable, Dr. Rogers said.

When weighing treatment options with elderly patients, he emphasized that careful consideration should be given to whether the “time needed to benefit from a Mohs procedure is longer than the patient’s life expectancy.” Furthermore, a decision not to treat does not have to be the last word. “We need to have an honest dialogue on the consequences of nontreatment, but part of that should be that just because we don’t treat today, doesn’t mean we can’t treat it tomorrow, if necessary.”

Of note, he added, “more than 100,00 patients have surgery for basal cell carcinoma [BCC] in their last year of life.” And that figure will likely rise exponentially if population projections come to fruition, considering that the population of people over the age of 85 is predicted to increase to nearly 18 million in 2050, from 5.8 million in 2012, Dr. Rogers said.

Until more research emerges on how to best treat this age group, Dr. Rogers noted that experts recommend that for elderly patients, “treatment should be individualized with consideration of active monitoring of primary BCC that is not in the H-zone, asymptomatic, smaller than 1 cm, with treatment initiated if there is substantial growth or symptoms.” Ultimately, he urged surgeons to “be sensitive and treat our patients like ourselves or our family members.”
 

When appropriate – Mohs is safe in the very elderly

Taking on the issue in a separate presentation, Deborah MacFarlane, MD, professor of dermatology and head and neck surgery at MD Anderson Cancer Center, Houston, said that for skin cancer cases that warrant treatment, clinicians should not let age alone stand in the way of Mohs surgery.

The evidence of its safety in the elderly dates back to a paper published in 1997 that Dr. MacFarlane coauthored, describing Mohs surgery of BCCs, squamous cell cancers (SCCs), and melanomas among 115 patients aged 90 and older (average, 92.4 years) who had an average of 1.9 comorbid medical conditions, and were taking an average of 2.3 medications. “Overall, we had just one complication among the patients,” she said.

In a subsequent paper, Dr. MacFarlane and her colleagues found that age at the time of Mohs surgery, even in older patients, was unrelated to survival, stage of cancer, or the type of repair. “We have concluded that this rapidly growing segment of the population can undergo Mohs surgery and should not be relegated to less effective treatment out of fear of its affecting their survival,” Dr. MacFarlane said.

She agreed with the concern about frailty and hence functionality, which may need to be factored in when making a decision to perform Mohs surgery. “I think this is something we do intuitively anyway,” she added. “We’re going to offer Mohs to someone who we think will survive and who is in relatively good health,” Dr. MacFarlane noted.

The point is illustrated in a new multicenter study of 1,181 patients at 22 U.S. sites, aged 85 years and older with nonmelanoma skin cancer referred for Mohs surgery. In the study, published in JAMA Dermatology after the ACMS meeting, patients who had Mohs surgery were almost four times more likely to have high functional status (P < .001) and were more likely to have facial tumors (P < .001), compared with those who had an alternate surgery.

The main reasons provided by the surgeons for opting to treat with Mohs included a patient’s desire for treatment with a high cure rate (66%), good/excellent patient functional status for age (57%), and a high risk associated with the tumor based on histology (40%), noted Dr. MacFarlane, one of the authors.

She reiterated the point raised by Dr. Rogers that “this is something we’re going to increasingly face,” noting that people over 85 represent the fastest growing segment of the population. “I have more patients over the age of 100 than I’ve ever had before,” she said.

Nevertheless, her own experience with elderly patients speaks to the safety of Mohs surgery in this population: Dr. MacFarlane reported a review of her practice’s records of 171 patients aged 85 years and older between May 2016 and May 2022, who received 414 separate procedures, without a single complication.

Sharing many of Dr. Rogers’ concerns about using caution in at-risk patients, Dr. MacFarlane offered recommendations for the optimal treatment of elderly patients receiving Mohs, including handling tissue delicately, and “keep undermining to a minimum.” She noted that intermediate closures and full thickness skin grafts are ideal closures for the elderly, while flaps may be performed in selected robust skin. It is also important to involve caretakers from the onset, talk and listen to patients – and play their choice of music during treatment, she said.

Commenting on the debate, comoderator Nahid Y. Vidal, MD, of the department of dermatology, Mayo Clinic, Rochester, Minn., noted that the expanding older population is accompanied by increases in skin cancer, in addition to more immunosenescence that is related to development of infections, autoimmune disease, and malignant tumors.

“In our academic practice, as with both the reference speakers, we do frequently see elderly, and not uncommonly the super-elderly,” she told this news organization. “The take-home point for me is to treat your whole patient, not just the tumor,” considering social factors, frailty/spry factor, and preferences, “and to do the humanistic thing, while also remaining evidence based,” she said.

“Don’t assume that increased age translates to morbidity, worse outcomes, or futility of treatment,” she added. “Chances are, if [a patient] made it to 90 years old with only a few medications and few medical problems, they may make it to 100, so why put the patient at risk for metastasis and death from a treatable/curable skin cancer,” in the case of SCC, she said.

“By the same token, why not perform more conservative treatments such as ED&C [electrodesiccation and curettage] for very low-risk skin cancers in low-risk locations, such as a superficial basal cell carcinoma on the trunk?” Overall, instead of trying to determine how long a super-elderly individual will live, Dr. Vidal said that “it’s better to educate the patient, engage in a discussion about goals of care, and to make few assumptions.”

Dr. Rogers, Dr. MacFarlane, and Dr. Vidal report no disclosures.

“Pandemic-related treatment delay has caused increased suffering and morbidity for countless skin cancer patients across the U.S.,” he said. “In general, not treating skin cancer and hoping it’s not going to grow or having significant delays in treatment are a recipe for disastrous outcomes.”

That said, active monitoring may be appropriate “for select small cancers that tend to grow slowly in the very elderly,” added Dr. Rogers, the incoming ACMS president. Among the key situations where the benefits of active monitoring may outweigh the risks of surgery are small, slowly growing cancers, when frailty is an issue.

Frailty has been equated to compromised functionality, which can increase the risk of an array of complications, including prolonged wound healing and secondary complications stemming from immobility. The toll those issues can take on patients’ quality of life can be considerable, Dr. Rogers said.

When weighing treatment options with elderly patients, he emphasized that careful consideration should be given to whether the “time needed to benefit from a Mohs procedure is longer than the patient’s life expectancy.” Furthermore, a decision not to treat does not have to be the last word. “We need to have an honest dialogue on the consequences of nontreatment, but part of that should be that just because we don’t treat today, doesn’t mean we can’t treat it tomorrow, if necessary.”

Of note, he added, “more than 100,00 patients have surgery for basal cell carcinoma [BCC] in their last year of life.” And that figure will likely rise exponentially if population projections come to fruition, considering that the population of people over the age of 85 is predicted to increase to nearly 18 million in 2050, from 5.8 million in 2012, Dr. Rogers said.

Until more research emerges on how to best treat this age group, Dr. Rogers noted that experts recommend that for elderly patients, “treatment should be individualized with consideration of active monitoring of primary BCC that is not in the H-zone, asymptomatic, smaller than 1 cm, with treatment initiated if there is substantial growth or symptoms.” Ultimately, he urged surgeons to “be sensitive and treat our patients like ourselves or our family members.”
 

When appropriate – Mohs is safe in the very elderly

Taking on the issue in a separate presentation, Deborah MacFarlane, MD, professor of dermatology and head and neck surgery at MD Anderson Cancer Center, Houston, said that for skin cancer cases that warrant treatment, clinicians should not let age alone stand in the way of Mohs surgery.

The evidence of its safety in the elderly dates back to a paper published in 1997 that Dr. MacFarlane coauthored, describing Mohs surgery of BCCs, squamous cell cancers (SCCs), and melanomas among 115 patients aged 90 and older (average, 92.4 years) who had an average of 1.9 comorbid medical conditions, and were taking an average of 2.3 medications. “Overall, we had just one complication among the patients,” she said.

In a subsequent paper, Dr. MacFarlane and her colleagues found that age at the time of Mohs surgery, even in older patients, was unrelated to survival, stage of cancer, or the type of repair. “We have concluded that this rapidly growing segment of the population can undergo Mohs surgery and should not be relegated to less effective treatment out of fear of its affecting their survival,” Dr. MacFarlane said.

She agreed with the concern about frailty and hence functionality, which may need to be factored in when making a decision to perform Mohs surgery. “I think this is something we do intuitively anyway,” she added. “We’re going to offer Mohs to someone who we think will survive and who is in relatively good health,” Dr. MacFarlane noted.

The point is illustrated in a new multicenter study of 1,181 patients at 22 U.S. sites, aged 85 years and older with nonmelanoma skin cancer referred for Mohs surgery. In the study, published in JAMA Dermatology after the ACMS meeting, patients who had Mohs surgery were almost four times more likely to have high functional status (P < .001) and were more likely to have facial tumors (P < .001), compared with those who had an alternate surgery.

The main reasons provided by the surgeons for opting to treat with Mohs included a patient’s desire for treatment with a high cure rate (66%), good/excellent patient functional status for age (57%), and a high risk associated with the tumor based on histology (40%), noted Dr. MacFarlane, one of the authors.

She reiterated the point raised by Dr. Rogers that “this is something we’re going to increasingly face,” noting that people over 85 represent the fastest growing segment of the population. “I have more patients over the age of 100 than I’ve ever had before,” she said.

Nevertheless, her own experience with elderly patients speaks to the safety of Mohs surgery in this population: Dr. MacFarlane reported a review of her practice’s records of 171 patients aged 85 years and older between May 2016 and May 2022, who received 414 separate procedures, without a single complication.

Sharing many of Dr. Rogers’ concerns about using caution in at-risk patients, Dr. MacFarlane offered recommendations for the optimal treatment of elderly patients receiving Mohs, including handling tissue delicately, and “keep undermining to a minimum.” She noted that intermediate closures and full thickness skin grafts are ideal closures for the elderly, while flaps may be performed in selected robust skin. It is also important to involve caretakers from the onset, talk and listen to patients – and play their choice of music during treatment, she said.

Commenting on the debate, comoderator Nahid Y. Vidal, MD, of the department of dermatology, Mayo Clinic, Rochester, Minn., noted that the expanding older population is accompanied by increases in skin cancer, in addition to more immunosenescence that is related to development of infections, autoimmune disease, and malignant tumors.

“In our academic practice, as with both the reference speakers, we do frequently see elderly, and not uncommonly the super-elderly,” she told this news organization. “The take-home point for me is to treat your whole patient, not just the tumor,” considering social factors, frailty/spry factor, and preferences, “and to do the humanistic thing, while also remaining evidence based,” she said.

“Don’t assume that increased age translates to morbidity, worse outcomes, or futility of treatment,” she added. “Chances are, if [a patient] made it to 90 years old with only a few medications and few medical problems, they may make it to 100, so why put the patient at risk for metastasis and death from a treatable/curable skin cancer,” in the case of SCC, she said.

“By the same token, why not perform more conservative treatments such as ED&C [electrodesiccation and curettage] for very low-risk skin cancers in low-risk locations, such as a superficial basal cell carcinoma on the trunk?” Overall, instead of trying to determine how long a super-elderly individual will live, Dr. Vidal said that “it’s better to educate the patient, engage in a discussion about goals of care, and to make few assumptions.”

Dr. Rogers, Dr. MacFarlane, and Dr. Vidal report no disclosures.

A final long-term analysis of a study designed to evaluate the safety of a common osteoporosis drug used to treat bone loss in women who were treated for breast cancer, finds the treatment not only reduces fractures long-term, but it may also improve overall survival and increase bone density.

The final analysis of “Adjuvant Denosumab in Breast Cancer (ABCSG-18)” was presented at the annual meeting of the American Society of Clinical Oncology.

“Adjuvant denosumab should be considered for routine clinical use in postmenopausal patients with HR+ breast cancer on aromatase inhibitors treatment,” said the study’s author Michael Gnant, MD, FACS, director of surgery for the Medical University of Vienna.

Denosumab is currently recommended by ASCO as a treatment option for osteoporosis in patients who were successfully treated for nonmetastatic disease.

ABCSG-18 was a prospective, double-blind, placebo-controlled, phase 3 trial that comprised 3,420 patients (mean age 64.5 years) from 58 treatment centers. It included postmenopausal patients with early HR+ breast cancer who were treated with aromatase inhibitors between 2006 and 2013. Among the patients, 1,711 received denosumab 60 mg and 1,709 received a placebo every 6 months.

The primary endpoint was time to first clinical fracture, and the secondary disease outcome-related endpoints were disease-free survival, bone metastasis–free survival, and overall survival.

The hazard ratio for disease-free survival in the denosumab group was 0.83 (95% confidence interval [CI], 0.71-0.97, P = .02) after a median follow-up of 8 years. Disease-free survival (DFS) was 69.0% in the placebo arm and 74.4% in the denosumab arm, with events occurring in 19.8% of patients overall, including deaths in 8.3%.

Bone metastasis–free survival (BMFS) rates were 81.3% and 85.7% in the placebo and denosumab arms, respectively (HR = 0.81, 95% CI, 0.65-1.00, P = .05). Overall survival was 83.6% and 88.8% in the placebo and denosumab arms, respectively (HR = 0.80; 95% CI, 0.63-1.01, P = .06).

There were no new toxicities, nor was there a single positive case of osteonecrosis of the jaw (ONJ) during the study period, which may be due to the low dosage of denosumab. The bone protection dose of denosumab is much lower than that used for treatment of metastases which can be 12 times higher. In those cases, 4%-6% of patients may develop ONJ. “At these very low doses, even after 30,000 treatment years, we did not observe a single confirmed ONJ case,” he said.

Exploratory observations showed the majority of events to include distant recurrences in bone, liver, and lungs. Analysis revealed a trend toward reduction in contralateral breast cancer in the denosumab arm (24 versus 29 events), with a reduction in second non-breast primary malignancies (101 versus 127 events).

In a much earlier ABCSG-18 study from 2015, the primary endpoint of fracture risk was reduced significantly with denosumab (HR = 0.50, P < .0001), with highly significantly longer time to first clinical fracture, higher percent increase in bone mineral density (P < .0001 for both) and fewer vertebral fractures (P = .009). There is evidence that older generation bisphosphonates have potential beyond bone health, such as reducing metabolism (which benefits bone turnover), and improving breast cancer outcomes. These benefits sparked interest in potential long-term cancer reduction with denosumab, Dr. Gnant said.

“Bone marrow is a putative source of late relapse. Tumor cells can harbor there in a quiescent state for 10-15-20 years, and then for some reason wake up and cause metastases. So, all bone-targeted agents are also evaluated for reductions in cancer which is what we were looking to investigate here in this 15-year data,” he said. Denosumab is more targeted than the bisphosphonates, and directly inhibits the RANK ligand which is an important mediator of osteoclast activation. “This ligand is believed to support metastases in the process of waking up,” Dr. Gnant said.

A limitation of the study is that the outcome endpoints of ABCSG-18 are secondary ones, making the results technically descriptive. The study was sponsored by Amgen.

Patients with relapsed or refractory B cell non-Hodgkin lymphoma responded positively to a new therapy based on genome editing in early results from a phase 1 study, according to a news release from manufacturer Caribou Biosciences.

In the first-in-human, phase 1 open-label study, known as ANTLER, 5 out of 5 patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL) responded to a single dose of CB-010, an allogeneic CAR-T cell therapy designed to boost antitumor activity, according to the company.

The use of chimeric antigen receptor (CAR) T-cell therapy involves taking T cells out of the body, reprogramming them with CAR to better equip them to kill cancer cells, and putting them back into the body.

The study consists of two sections: an initial dose escalation following a 3 + 3 design, with prespecified, increasing doses, followed by an expanded trial in which all patients receive CB-010 at the dose determined in the first section.

The study population included 6 adults with r/r B-NHL who had relapsed after previous treatment with a median of 3 prior therapies. At baseline, all 6 patients underwent a lymphodepletion regimen consisting of cyclophosphamide at 60 mg/kg/day for 2 days, followed by 5 days of fludarabine at 25 mg/m²/day.

Then all patients received a single dose of 40x106 CAR-T cells. As of the Feb. 23, 2022, data cutoff date, 5 of the 6 patients had completed the 28-day dose-limiting toxicity (DLT) evaluation period. All 5 patients (100%) achieved a response; 4 achieved complete response and 1 achieved partial response. All 4 of the complete responders had ongoing complete response at 3 months, and the longest measured complete response was 6 months, according to the company.

“We are excited to see a 100% overall response rate with CB-010 at dose level 1 for these patients who have limited treatment options,” said Dr. Syed Rizvi, chief medical officer for Caribou Biosciences, in the press release. “We believe this initial level of activity is unparalleled for a single, starting dose of cell therapy. CB-010 was generally well-tolerated, with adverse events routinely observed in autologous or allogeneic anti-CD19 CAR-T cell therapies,” he said.

Based on the promising safety and efficacy results, the company is enrolling patients in a second cohort for treatment at dose level 2 (80x106 CAR-T cells), according to the news release.

Another allogeneic CAR-T cell therapy known as ALLO-501A is being studied in a similar trial conducted by the Moffitt Cancer Center.

Overall, CB-010 was well-tolerated, according to Caribou Biosciences. No cases of graft-versus-host disease were reported. A total of 3 patients developed grade 3 or 4 adverse events (AEs) within the first 28 days; the most common were neutropenia (50%), thrombocytopenia (33%), anemia (17%), and hypogammaglobulinemia (17%). One patient experienced both grade 1 cytokine release syndrome (CRS) and grade 3 Immune effector cell-Associated Neurotoxicity Syndrome (ICANS). This response was characterized as a dose-limiting toxicity. The patient was treated with tocilizumab and steroids, recovered within 39 hours, and went on to achieve a complete response, according to the company.

Although the safety profile in the current study was promising, prior research suggest that concerns associated with CRS and ICANS should not be ignored and may be barriers to treatment.

In an article published in Bone Marrow Transplant in 2021, Dr. Vipul Sheth and Dr. Jordan Gauthier of the Fred Hutchinson Cancer Center, Seattle, noted that adverse effects may remain a challenge to widespread use of CAR-T in patients with refractory or relapsed acute lymphoblastic leukemia, for which it has been approved by the U.S. Food and Drug Administration and several European agencies. However, “there is mounting evidence that earlier, and potentially more targeted, interventions can reduce these toxicities,” they wrote.
 

Study provides solid stepping stone

“CRS and ICANS are mild in most patients but can be severe and sometimes life-threatening in a subset of patients undergoing CD19 CAR T-cell therapy,” Dr. Gauthier said in an interview. “Different strategies are being investigated to mitigate or treat severe toxicities, such as the use of prophylactic corticosteroids, anakinra, lenzilumab, itacitinib. I am hopeful we will soon manage to prevent toxicities while maintaining potent anti-tumor effects,” he said.

“While autologous CD19 CAR-T cells have high efficacy in patients with refractory/relapsed large B-cell lymphoma, product manufacturing remains a complicated and lengthy process in the autologous setting,” Dr. Gauthier noted. “Commercial CAR T-cell manufacturing takes approximately 3-4 weeks, sometimes longer. Some patients won’t survive long enough to receive their infusion. In some patients, T-cell function is dramatically impaired, due to prior therapies or to the disease itself,” he said.

Dr. Gauthier said he was not surprised but that he was encouraged by the apparent early success of the ANTLER study. “The proof-of-concept that allogeneic CD19-targeted CAR T cells can induce high response rates in r/r LBCL has already been established,” he said. “Having said that, it is comforting to see prior findings confirmed by this new study, and those results are exciting for the field,” he added.

As for additional research, “we need longer follow-up after allogeneic CD19-targeted CAR T-cell therapy to ensure responses are durable,” Dr. Gauthier explained. “We also need to better understand the biology driving the antitumor effects and the side effects of CAR T-cells. This will help us build more efficacious and safer CAR T-cell therapies,” he said.
 

Response and side effects show promise for future research

The therapy is “the best CAR-T product” that clinicians can provide for patients knowing that autologous CAR-T works, said Dr. Ahmed Galal, of Duke University, Durham, N.C., in an interview. The current research supports the use of this treatment immediately for patients, he added.

Dr. Galal said he was somewhat surprised, but pleasantly so, by the 100% response rate. This rate is likely because of the small number of patients and may not hold up in further research, but “even 90% would be an amazing achievement,” he said. The tolerable safety profile is encouraging as well, he emphasized. Dr. Galal said that he did not foresee any real barriers to expanded use of the therapy and that technology should make it easier to deliver at authorized centers.

Limitations to the current study are those common to all phase 1 trials, such as the strict inclusion criteria, Dr. Galal said. As research progresses to phase 2, “I don’t think it will be an obstacle to find patients,” he said. However, patients should be aware of side effects, and clinicians should maintain a culture of education to help them understand the value of the therapy, he added.

The complete data from the preliminary findings are scheduled to be presented at the European Hematology Association (EHA) 2022 Hybrid Congress, Vienna, in June, as abstract P1455, titled “First-in-human trial of CB-010, a CRISPR-edited allogeneic anti-CD19 CAR-T cell therapy with a PD-1 knock out, in patients with relapsed or refractory B cell non-Hodgkin lymphoma (ANTLER study).” The findings are scheduled to be presented by Loretta J. Nastoupil, MD, of the University of Texas MD Anderson Cancer Center, according to Caribou Biosciences.

Dr. Gauthier had no financial conflicts to disclose. Dr. Galal had no financial conflicts to disclose.

This will help us build more efficacious and safer CAR T-cell therapies,” he said.
 

Response and side effects show promise for future research

The therapy is “the best CAR-T product” that clinicians can provide for patients knowing that autologous CAR-T works, said Dr. Ahmed Galal, of Duke University, Durham, N.C., in an interview. The current research supports the use of this treatment immediately for patients, he added.

Dr. Galal said he was somewhat surprised, but pleasantly so, by the 100% response rate. This rate is likely because of the small number of patients and may not hold up in further research, but “even 90% would be an amazing achievement,” he said. The tolerable safety profile is encouraging as well, he emphasized. Dr. Galal said that he did not foresee any real barriers to expanded use of the therapy and that technology should make it easier to deliver at authorized centers.

Limitations to the current study are those common to all phase 1 trials, such as the strict inclusion criteria, Dr. Galal said. As research progresses to phase 2, “I don’t think it will be an obstacle to find patients,” he said. However, patients should be aware of side effects, and clinicians should maintain a culture of education to help them understand the value of the therapy, he added.

The complete data from the preliminary findings are scheduled to be presented at the European Hematology Association (EHA) 2022 Hybrid Congress, Vienna, in June, as abstract P1455, titled “First-in-human trial of CB-010, a CRISPR-edited allogeneic anti-CD19 CAR-T cell therapy with a PD-1 knock out, in patients with relapsed or refractory B cell non-Hodgkin lymphoma (ANTLER study).” The findings are scheduled to be presented by Loretta J. Nastoupil, MD, of the University of Texas MD Anderson Cancer Center, according to Caribou Biosciences.

Patients with relapsed or refractory B cell non-Hodgkin lymphoma responded positively to a new therapy based on genome editing in early results from a phase 1 study, according to a news release from manufacturer Caribou Biosciences.

In the first-in-human, phase 1 open-label study, known as ANTLER, 5 out of 5 patients with relapsed or refractory B cell non-Hodgkin lymphoma (r/r B-NHL) responded to a single dose of CB-010, an allogeneic CAR-T cell therapy designed to boost antitumor activity, according to the company.

The use of chimeric antigen receptor (CAR) T-cell therapy involves taking T cells out of the body, reprogramming them with CAR to better equip them to kill cancer cells, and putting them back into the body.

The study consists of two sections: an initial dose escalation following a 3 + 3 design, with prespecified, increasing doses, followed by an expanded trial in which all patients receive CB-010 at the dose determined in the first section.

The study population included 6 adults with r/r B-NHL who had relapsed after previous treatment with a median of 3 prior therapies. At baseline, all 6 patients underwent a lymphodepletion regimen consisting of cyclophosphamide at 60 mg/kg/day for 2 days, followed by 5 days of fludarabine at 25 mg/m²/day.

Then all patients received a single dose of 40x106 CAR-T cells. As of the Feb. 23, 2022, data cutoff date, 5 of the 6 patients had completed the 28-day dose-limiting toxicity (DLT) evaluation period. All 5 patients (100%) achieved a response; 4 achieved complete response and 1 achieved partial response. All 4 of the complete responders had ongoing complete response at 3 months, and the longest measured complete response was 6 months, according to the company.

“We are excited to see a 100% overall response rate with CB-010 at dose level 1 for these patients who have limited treatment options,” said Dr. Syed Rizvi, chief medical officer for Caribou Biosciences, in the press release. “We believe this initial level of activity is unparalleled for a single, starting dose of cell therapy. CB-010 was generally well-tolerated, with adverse events routinely observed in autologous or allogeneic anti-CD19 CAR-T cell therapies,” he said.

Based on the promising safety and efficacy results, the company is enrolling patients in a second cohort for treatment at dose level 2 (80x106 CAR-T cells), according to the news release.

Another allogeneic CAR-T cell therapy known as ALLO-501A is being studied in a similar trial conducted by the Moffitt Cancer Center.

Overall, CB-010 was well-tolerated, according to Caribou Biosciences. No cases of graft-versus-host disease were reported. A total of 3 patients developed grade 3 or 4 adverse events (AEs) within the first 28 days; the most common were neutropenia (50%), thrombocytopenia (33%), anemia (17%), and hypogammaglobulinemia (17%). One patient experienced both grade 1 cytokine release syndrome (CRS) and grade 3 Immune effector cell-Associated Neurotoxicity Syndrome (ICANS). This response was characterized as a dose-limiting toxicity. The patient was treated with tocilizumab and steroids, recovered within 39 hours, and went on to achieve a complete response, according to the company.

Although the safety profile in the current study was promising, prior research suggest that concerns associated with CRS and ICANS should not be ignored and may be barriers to treatment.

In an article published in Bone Marrow Transplant in 2021, Dr. Vipul Sheth and Dr. Jordan Gauthier of the Fred Hutchinson Cancer Center, Seattle, noted that adverse effects may remain a challenge to widespread use of CAR-T in patients with refractory or relapsed acute lymphoblastic leukemia, for which it has been approved by the U.S. Food and Drug Administration and several European agencies. However, “there is mounting evidence that earlier, and potentially more targeted, interventions can reduce these toxicities,” they wrote.
 

Study provides solid stepping stone

“CRS and ICANS are mild in most patients but can be severe and sometimes life-threatening in a subset of patients undergoing CD19 CAR T-cell therapy,” Dr. Gauthier said in an interview. “Different strategies are being investigated to mitigate or treat severe toxicities, such as the use of prophylactic corticosteroids, anakinra, lenzilumab, itacitinib. I am hopeful we will soon manage to prevent toxicities while maintaining potent anti-tumor effects,” he said.

“While autologous CD19 CAR-T cells have high efficacy in patients with refractory/relapsed large B-cell lymphoma, product manufacturing remains a complicated and lengthy process in the autologous setting,” Dr. Gauthier noted. “Commercial CAR T-cell manufacturing takes approximately 3-4 weeks, sometimes longer. Some patients won’t survive long enough to receive their infusion. In some patients, T-cell function is dramatically impaired, due to prior therapies or to the disease itself,” he said.

Dr. Gauthier said he was not surprised but that he was encouraged by the apparent early success of the ANTLER study. “The proof-of-concept that allogeneic CD19-targeted CAR T cells can induce high response rates in r/r LBCL has already been established,” he said. “Having said that, it is comforting to see prior findings confirmed by this new study, and those results are exciting for the field,” he added.

Another glucagonlike peptide-1 (GLP1) agonist, dulaglutide (Trulicity, Lilly), is poised to be a new option for glycemic control in youth aged 10-18 years with type 2 diabetes, given as a weekly injection, based on the AWARD-PEDS clinical trial.

The U.S. Food and Drug Administration has already approved daily injection liraglutide (Victoza, Novo Nordisk) in 2019 and weekly exenatide (Bydureon/Bydureon BCise, AstraZeneca) in 2021 for glycemic control in young patients with type 2 diabetes, both of which are also GLP-1 agonists.  

AWARD-PEDS showed that youth with type 2 diabetes and obesity treated with or without metformin or basal insulin who received weekly injections of 0.75 mg or 1.5 mg of dulaglutide had lower hemoglobin A1c at 26 weeks than patients who received placebo.

Eli Lilly is now submitting these trial results to the FDA for this indication.

Dulaglutide was cleared for use in adults with type 2 diabetes in the United States in 2014 and was additionally approved for reducing the risk of major adverse cardiovascular events (MACE) in adults with type 2 diabetes at high risk of such events in 2020.

The most common adverse symptoms were gastrointestinal, and the safety profile was consistent with that in adults. However, the drug had no effect on body mass index.

The study was simultaneously published in the New England Journal of Medicine and presented as a late-breaking poster at the annual scientific sessions of the American Diabetes Association in New Orleans.

Might dulaglutide target pathophysiologic impairments in youth?

Dulaglutide would “offer a new treatment that targets the pathophysiologic impairments of type 2 diabetes in youth,” Silva A. Arslanian, MD, lead investigator, told this news organization.

Exenatide is also given as a weekly injection but is associated with a smaller decrease in A1c and does not improve fasting glucose concentrations, plus it requires more steps compared with the dulaglutide single-use pen, said Dr. Arslanian, who is scientific director at the Center for Pediatric Research in Obesity & Metabolism, UPMC Children’s Hospital of Pittsburgh.

“Liraglutide is a daily injection, and I believe most patients, particularly adolescents, would prefer a weekly injection,” she added.  

Invited to comment, Elvira Isganaitis, MD, MPH, said “the significance of this paper lies in the fact that options for treating type 2 diabetes in children are currently much more limited than in adults – which is a major problem given recent studies that show that type 2 diabetes in youth is much more aggressive and more likely to cause complications early in the disease course.”

Dr. Isganaitis was not involved with the trial but is an investigator for the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study.

“With supply chain shortages and health insurance coverage issues that are common in the U.S., it would be helpful to have more than one FDA-approved option for a weekly GLP-1 receptor agonist in children [and] access to other classes of medications,” added Dr. Isganaitis, a pediatric endocrinologist at the Joslin Diabetes Center, Boston.

Phase 3 trials of sodium-glucose cotransporter 2 (SGLT2) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors in youth with type 2 diabetes are also ongoing, Dr. Arslanian noted, “but as always, recruitment is slow with adolescents.”

“I am not optimistic that DPP4 inhibitors will have a place in the treatment of youth with type 2 diabetes,” she said. A recent study showed the addition of sitagliptin to metformin in youth with type 2 diabetes did not provide durable improvement in glycemic control.

Potentially promising therapy

In their published article, Dr. Arslanian and colleagues write that “considering the progressive increase in [A1c] over time that was observed in the TODAY trial, with 34% of youths having [an A1c] of at least 10% after up to 15 years of follow-up, we believe that the effects of dulaglutide therapy appear to be potentially promising.”

The TODAY trial showed that more than 50% of youth with type 2 diabetes taking metformin failed to maintain glycemic control within a median of 11.5 months, Dr. Arslanian elaborated, and over time their A1c escalated while their beta-cell function deteriorated rapidly, and complications progressed quickly.

“Therefore,” she noted, “considering that dulaglutide and the GLP-1 receptor agonist class of drugs improve A1c, improve beta-cell function, suppress glucagon concentrations, and improve insulin sensitivity, dulaglutide would provide a promising new treatment option for youth with type 2 diabetes.”

Phase 3 superiority trial

The AWARD-PEDS trial included 154 youth with type 2 diabetes and a BMI greater than the 85th percentile for their age and sex at 46 centers in nine countries. Researchers randomized participants 1:1:1 to the two doses of dulaglutide or placebo for 26 weeks, followed by a 26-week open-label study (during which the placebo group received 0.75 mg dulaglutide) and a 4-week safety extension. 

Participants were a mean age of 14.5 years and had a mean BMI of 34 kg/m².

In each of the dulaglutide groups, roughly 66% of patients were female and 58% were White, 18% were Black, and about 57% were Hispanic. They had a mean weight of 91 kg (200 lb) and a mean A1c of about 8%; 62% were taking metformin only, 27% were taking metformin plus basal insulin, 3% were taking basal insulin only, and 10% were on diet and exercise only.

At 26 weeks, mean A1c increased by 0.6% in the placebo group but decreased by 0.6% in the 0.75-mg dulaglutide group and by 0.9% in the 1.5-mg dulaglutide group (P < .001 for both comparisons versus placebo).

Also at 26 weeks, more participants in the pooled dulaglutide groups than in the placebo group had an A1c <7.0% (51% vs. 14%; P < .001).

Fasting glucose concentration increased in the placebo group (+17.1 mg/dL ) and decreased in the pooled dulaglutide groups (–18.9 mg/dL; P < .001).

There were no group differences in BMI or adiposity-related parameters even at 52 weeks.

“I believe adolescents may be somewhat resistant to the weight-reducing effects of GLP-1 agonists in diabetes trials (liraglutide and exenatide youth type 2 diabetes trials showed the same thing) and they may need higher doses,” Dr. Arslanian speculated.

“Only future studies will be able to address this issue,” she concluded.

The study was funded by Eli Lilly. Dr. Arslanian has disclosed being a consultant for Eli Lilly, Novo Nordisk, and Rhythm Pharmaceuticals; participating in data safety monitoring for AstraZeneca and Eli Lilly trials; and receiving institutional research funding from Eli Lilly and Novo Nordisk. Dr. Isganaitis has disclosed receiving research funding (paid to her institution) from Dexcom and AstraZeneca.
