The first biosimilar for Humira, adalimumab-atto (Amjevita), is now available in the United States, according to an announcement on Jan. 31 by the manufacturer, Amgen. At least seven other U.S. Food and Drug Administration–approved Humira biosimilars are expected to become available later in 2023.

Amjevita was approved by the FDA in September 2016 for multiple inflammatory diseases, including rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis, and plaque psoriasis. The delayed launch was part of a global settlement with Humira’s manufacturer, AbbVie.

Humira (adalimumab) has been available since 2002 and is consistently one of the top-selling drugs in the United States. A single 40-mg Amjevita pen device will be available at two prices: a list price (wholesale acquisition cost) of $1,557.59, 55% below the current Humira list price, and a list price of $3,288.24, 5% below the current Humira list price, according to Amgen.

“Amgen’s goal is to provide broad access for patients by offering two options to health plans and pharmacy benefit managers,” the company said in the press release.

Patients are less likely to benefit from the more significant discount, said Marta Wosinska, PhD, a health care economist at the Brookings Institute in Washington, DC. It's expected that insurance companies will use the higher list price for Amjevita, she said, as this higher price will also likely have higher rebates. Rebates are payments to health insurance payers provided by drug manufacturers to promote use of an expensive drug. Some pharmacy benefit managers have already said that they plan to charge patients the same amount for Humira as its biosimilars, Dr. Wosinska said.

"For an existing patient, there's really no incentive for them to switch," she said in an interview.

So far only one insurance company, Kaiser Permanente, has plans to switch patients over to biosimilars, according to the health policy podcast Tradeoffs, and the insurer will stop covering Humira by the end of this year.

The Food and Drug Administration has granted accelerated approval to pirtobrutinib (Jaypirca) for relapsed or refractory mantle cell lymphoma (MCL) after at least two lines of systemic therapy, including a Bruton’s tyrosine kinase inhibitor.

Pirtobrutinib is the first and only noncovalent Bruton’s tyrosine kinase inhibitor approved for use in this MCL setting, manufacturer Eli Lilly noted in a press release.

“The approval of Jaypirca represents an important advance for patients with relapsed or refractory MCL, who currently have limited options and historically have had a poor prognosis following discontinuation of treatment with a covalent Bruton’s tyrosine kinase inhibitor,” senior author Michael Wang, MD, University of Texas MD Anderson Cancer Center, Houston, said in the release.

The approval was based on efficacy demonstrated in the open-label, single-arm, phase 1/2 BRUIN trial – a multicenter study assessing 200 mg once-daily oral pirtobrutinib monotherapy in 120 patients with MCL who had previously received a Bruton’s tyrosine kinase inhibitor, most often ibrutinib (Imbruvica, 67%) acalabrutinib (Calquence, 30%) and zanubrutinib (Brukinsa, 8%). Pirtobrutinib was continued until disease progression or unacceptable toxicity.

Study participants had a median of three prior lines of therapy, and 83% discontinued their last Bruton’s tyrosine kinase inhibitor because of refractory or progressive disease.

The overall response rate in pirtobrutinib-treated patients was 50% with a complete response rate of 13%. Estimated median duration of response was 8.3 months, and the estimated duration of response at 6 months occurred in nearly two-thirds of patients.

Adverse reactions that occurred in at least 15% of patients included fatigue, musculoskeletal pain, diarrhea, edema, dyspnea, pneumonia, and bruising. Grade 3 or 4 laboratory abnormalities occurring in at least 10% of patients included decreased neutrophil counts, lymphocyte counts, and platelet counts.

Prescribing information for pirtobrutinib includes warnings and precautions for infections, hemorrhage, cytopenias, atrial fibrillation and flutter, and second primary malignancies, noted the FDA, which granted priority review, fast track designation, and orphan drug designation for the application submitted by Eli Lilly.

“Jaypirca can reestablish Bruton’s tyrosine kinase inhibition in MCL patients previously treated with a covalent Bruton’s tyrosine kinase inhibitor (ibrutinib, acalabrutinib, or zanubrutinib) and extend the benefit of targeting the Bruton’s tyrosine kinase pathway,” according to Eli Lilly’s release.

Dr. Wang added that the agent “has the potential to meaningfully impact the treatment paradigm for relapsed and refractory MCL patients.”

Meghan Gutierrez, CEO at the Lymphoma Research Foundation, also noted that “the approval of Jaypirca brings a new treatment option and, along with that, new hope for people with relapsed or refractory MCL.”

The drug is expected to be available in the United States in the coming weeks, and the confirmatory phase 3 BRUIN trial is currently enrolling patients, Eli Lilly announced. The company also indicated the list price would be $21,000 for a 30-day supply of the 200-mg dose.

Serious adverse events believed to be associated with the use of pirtobrutinib or any medicine or device should be reported to the FDA’s MedWatch Reporting System or by calling 1-800-FDA-1088.

A panel of advisers to the Food and Drug Administration unanimously supported an effort to simplify COVID-19 vaccinations, with the aim of developing a one-dose approach – perhaps annually – for the general population.

The FDA is looking to give clearer direction to vaccine makers about future development of COVID-19 vaccines. The plan is to narrow down the current complex landscape of options for vaccinations, and thus help increase use of these shots. 

COVID remains a serious threat, causing about 4,000 deaths a week recently, according to the Centers for Disease Control and Prevention. The 21 members of the Vaccines and Related Biological Products Advisory Committee (VRBPAC) on Jan. 26 voted unanimously “yes” on a single question posed by the FDA: 

“Does the committee recommend harmonizing the vaccine strain composition of primary series and booster doses in the U.S. to a single composition, e.g., the composition for all vaccines administered currently would be a bivalent vaccine (Original plus Omicron BA.4/BA.5)?”

In other words, would it be better to have one vaccine potentially combining multiple strains of the virus, instead of multiple vaccines – such as a two-shot primary series then a booster containing different combinations of viral strains.

The FDA will consider the panel’s advice as it outlines new strategies for keeping ahead of the evolving virus.

In explaining their support for the FDA plan, panel members said they hoped that a simpler regime would aid in persuading more people to get COVID vaccines.

Pamela McInnes, DDS, MSc, noted that it’s difficult to explain to many people that the vaccine works to protect them from more severe illness if they contract COVID after getting vaccinated. 

“That is a real challenge,” said Dr. McInness, retired deputy director of the National Center for Advancing Translational Sciences at the National Institutes of Health.

“The message that you would have gotten more sick and landed in the hospital resonates with me, but I’m not sure if it resonates with” many people who become infected, she said.
 

The plan

In the briefing document for the meeting, the FDA outlined a plan for transitioning from the current complex landscape of COVID-19 vaccines to a single vaccine composition for the primary series and booster vaccination. 

This would require harmonizing the strain composition of all COVID-19 vaccines; simplifying the immunization schedule for future vaccination campaigns to administer a two-dose series in certain young children and in older adults and persons with compromised immunity, and only one dose in all other individuals; and establishing a process for vaccine strain selection recommendations, similar in many ways to that used for seasonal influenza vaccines, based on prevailing and predicted variants that would take place by June to allow for vaccine production by September.

During the discussion, though, questions arose about the June target date. Given the production schedule for some vaccines, that date might need to shift, said Jerry Weir, PhD, director of the division of viral products at FDA’s Center for Biologics Evaluation and Research. 

“We’re all just going to have to maintain flexibility,” Dr. Weir said, adding that there is not yet a “good pattern” established for updating these vaccines. 
 

Increasing vaccination rates

There was broad consensus about the need to boost public support for COVID-19 vaccinations. While about 81% of the U.S. population has had at least one dose of this vaccine, only 15.3% have had an updated bivalent booster dose, according to the CDC.

“Anything that results in better public communication would be extremely valuable,” said committee member Henry H. Bernstein, DO, MHCM, of the Zucker School of Medicine at Hofstra/Northwell Health in Hempstead, N.Y.

But it’s unclear what expectations will be prioritized for the COVID vaccine program, he said. 

“Realistically, I don’t think we can have it all – less infection, less transmission, less severe disease, and less long COVID,” Dr. Bernstein said. “And that seems to be a major challenge for public messaging.” 
 

Panelists press for more data 

Other committee members also pressed for clearer targets in evaluating the goals for COVID vaccines, and for more robust data. 

Like his fellow VRBPAC members, Cody Meissner, MD, of Dartmouth’s Geisel School of Medicine, Hanover, N.H., supported a move toward harmonizing the strains used in different companies’ vaccines. But he added that it wasn’t clear yet how frequently they should be administered. 

“We need to see what happens with disease burden,” Dr. Meissner said. “We may or may not need annual vaccination. It’s just awfully early, it seems to me, in this process to answer that question.”

Among those serving on VRBPAC was one of the FDA’s more vocal critics on these points, Paul A. Offit, MD, a vaccine expert from Children’s Hospital of Philadelphia. Dr. Offit, for example, joined former FDA officials in writing a November opinion article for the Washington Post, arguing that the evidence for boosters for healthy younger adults was not strong.

At the Jan. 26 meeting, he supported the drive toward simplification of COVID vaccine schedules, while arguing for more data about how well these products are working.

“This virus is going to be with us for years, if not decades, and there will always be vulnerable groups who are going to be hospitalized and killed by the virus,” Dr. Offit said.

The CDC needs to provide more information about the characteristics of people being hospitalized with COVID infections, including their ages and comorbidities as well as details about their vaccine history, he said. In addition, academic researchers should provide a clearer picture of what immunological predictors are at play in increasing people’s risk from COVID.

“Then and only then can we really best make the decision about who gets vaccinated with what and when,” Dr. Offit said. 

VRBPAC member Ofer Levy, MD, PhD, also urged the FDA to press for a collection of more robust and detailed information about the immune response to COVID-19 vaccinations, such as a deeper look at what’s happening with antibodies.

“I hope FDA will continue to reflect on how to best take this information forward, and encourage – or require – sponsors to gather more information in a standardized way across these different arms of the human immune system,” Dr. Levy said. “So we keep learning and keep doing this better.”

In recapping the panel’s suggestions at the end of the meeting, Peter Marks, MD, PhD, the director of the FDA’s Center for Biologics Evaluation and Research, addressed the requests made during the day’s meeting about better data on how the vaccines work. 

“We heard loud and clear that we need to use a data-driven approach to get to the simplest possible scheme that we can for vaccination,” Dr. Marks said. “And it should be as simple as possible but not oversimplified, a little bit like they say about Mozart’s music.”

At the Jan. 26 meeting, he supported the drive toward simplification of COVID vaccine schedules, while arguing for more data about how well these products are working.

“This virus is going to be with us for years, if not decades, and there will always be vulnerable groups who are going to be hospitalized and killed by the virus,” Dr. Offit said.

The CDC needs to provide more information about the characteristics of people being hospitalized with COVID infections, including their ages and comorbidities as well as details about their vaccine history, he said. In addition, academic researchers should provide a clearer picture of what immunological predictors are at play in increasing people’s risk from COVID.

“Then and only then can we really best make the decision about who gets vaccinated with what and when,” Dr. Offit said. 

VRBPAC member Ofer Levy, MD, PhD, also urged the FDA to press for a collection of more robust and detailed information about the immune response to COVID-19 vaccinations, such as a deeper look at what’s happening with antibodies.

“I hope FDA will continue to reflect on how to best take this information forward, and encourage – or require – sponsors to gather more information in a standardized way across these different arms of the human immune system,” Dr. Levy said. “So we keep learning and keep doing this better.”

In recapping the panel’s suggestions at the end of the meeting, Peter Marks, MD, PhD, the director of the FDA’s Center for Biologics Evaluation and Research, addressed the requests made during the day’s meeting about better data on how the vaccines work. 

“We heard loud and clear that we need to use a data-driven approach to get to the simplest possible scheme that we can for vaccination,” Dr. Marks said. “And it should be as simple as possible but not oversimplified, a little bit like they say about Mozart’s music.”

The Food and Drug Administration has cleared the Tidepool Loop, a mobile application for use with compatible continuous glucose monitors (CGMs) and insulin pumps to enable automated insulin delivery.

Indicated for people with type 1 diabetes ages 6 years and up, the app algorithm was developed by the diabetes startup Tidepool, which already hosts a cloud-based platform for users to download and review data from different glucose meters, insulin pumps, and CGM systems. The Tidepool Loop project arose from patient-led, open-source initiatives to enable interoperability between the devices.

“The [FDA] authorization of the Tidepool Loop is a huge win for the type 1 diabetes (T1D) community and is a vital step towards a world where people with T1D can choose the pump, CGM, and algorithm that are best for them – and have all three work together seamlessly,” Aaron Kowalski, PhD, CEO of the advocacy organization JDRF, said in a statement.

JDRF helped support preclinical and clinical research in the development of the Loop algorithm, along with The Leona M. and Harry B. Helmsley Charitable Trust, the Tullman Foundation, and partnerships with device makers and donations from the T1D community.

Available by prescription only, the Tidepool app is for single patient use. It works with designated “integrated CGMs” and “alternate controller enabled pumps” to automatically increase, decrease, or suspend insulin delivery, based on the glucose readings and predicted values. The app can also recommend correction doses, which the user can confirm.

According to an FDA statement:“Tidepool Loop’s algorithm technology is designed to be compatible with other individual interoperable devices that meet prespecified acceptance criteria set forth in a validation and integration plan provided by the sponsor and cleared by the FDA as part of the premarket submission.”

Tidepool is finalizing agreements with the various device manufacturers “to create a seamless experience for both physicians prescribing Tidepool Loop and the patients using it,” according to a company statement.

Tidepool’s initial launch device partners have not yet been announced, but the company “has a development partnership with Dexcom and other yet-to-be-named medical device companies for future inclusion of their components with the Tidepool Loop platform,” the statement says.

U.S. health officials want to simplify the recommended COVID-19 vaccine protocol, making it more like the process for annual flu shots.

The U.S. Food and Drug Administration is suggesting a single annual shot. The formulation would be selected in June targeting the most threatening COVID-19 strains, and then people could get a shot in the fall when people begin spending more time indoors and exposure increases. 

Some people, such as those who are older or immunocompromised, may need more than one dose.

A national advisory committee is expected to vote on the proposal at a meeting Jan. 26.

People in the United States have been much less likely to get an updated COVID-19 booster shot, compared with widespread uptake of the primary vaccine series. In its proposal, the FDA indicated it hoped a single annual shot would overcome challenges created by the complexity of the process – both in messaging and administration – attributed to that low booster rate. Nine in 10 people age 12 or older got the primary vaccine series in the United States, but only 15% got the latest booster shot for COVID-19.

About half of children and adults in the U.S. get an annual flu shot, according to Centers for Disease Control and Prevention data.

The FDA also wants to move to a single COVID-19 vaccine formulation that would be used for primary vaccine series and for booster shots.

COVID-19 cases, hospitalizations, and deaths are trending downward, according to the data tracker from the New York Times. Cases are down 28%, with 47,290 tallied daily. Hospitalizations are down 22%, with 37,474 daily. Deaths are down 4%, with an average of 489 per day as of Jan. 22.

The U.S. Food and Drug Administration has approved bexagliflozin (Brenzavvy, TheracosBio) for the treatment of adults with type 2 diabetes.
 

Olivier Le Moal/Getty Images

The once-daily 20-mg oral sodium-glucose cotransporter 2 (SGLT2) inhibitor is indicated as an adjunct to diet and exercise to improve glycemic control for those with type 2 diabetes, but not type 1 diabetes. It can be used in adults with an estimated glomerular filtration rate (eGFR) > 30 mL/min per 1.73 m².

Approval was based on results from 23 clinical trials with more than 5,000 participants, including more than 300 patients with stage 3 kidney disease (eGFR < 60 and > 30 mL/min per 1.73 m²).

In the phase 3 studies, bexagliflozin significantly reduced hemoglobin A1c and fasting blood glucose at 24 weeks as monotherapy or as add-on to metformin and other glucose-lowering drugs and combinations. It also produced modest reductions in body weight and systolic blood pressure.

In the phase 3 Bexagliflozin Efficacy and Safety Trial (BEST) cardiovascular outcomes trial, the drug met its efficacy and safety objectives in patients at high cardiovascular risk. Noninferiority was demonstrated for the composite outcome of cardiovascular death, myocardial infarction, stroke, or unstable angina.

“As a class of drugs, SGLT2 inhibitors have shown tremendous benefit in treating adults with type 2 diabetes,” said Mason Freeman, MD, director of the Translational Research Center at Massachusetts General Hospital, Boston, in a press release from TheracosBio.

“Being involved in all of the clinical trials for Brenzavvy, I am greatly impressed with the efficacy of the drug in reducing blood glucose levels and I believe it is an important addition to the SGLT2 inhibitor class of drugs.”

As with other SGLT2 inhibitors, adverse events seen in the trials include ketoacidosis, lower limb amputation, volume depletion, urosepsis, pyelonephritis, Fournier’s gangrene, genital mycotic infections, and hypoglycemia when used with insulin or insulin secretagogues.

Bexagliflozin joins an already crowded field of SGLT2 inhibitors, some of which have been approved for additional cardiovascular and kidney indications.

Of interest, bexagliflozin was approved by the FDA for diabetes in cats in December 2022, as the first oral new animal drug to improve glycemic control in otherwise healthy cats with diabetes not previously treated with insulin.

A combination of HER2-targeted drugs used in breast cancer is now available for use in colorectal cancer.

The U.S. Food and Drug Administration has granted accelerated approval to tucatinib (Tukysa) in combination with trastuzumab for use in RAS wild-type, HER2-positive unresectable or metastatic colorectal cancer that has progressed after fluoropyrimidine, oxaliplatin, and irinotecan-based chemotherapy.

This is the first FDA-approved treatment for HER2-positive metastatic colorectal cancer, maker Seagen said in a Jan. 19 press release.

“Historically, patients with HER2-positive metastatic colorectal cancer who have progressed following frontline therapy have had poor outcomes. The FDA approval of a chemotherapy-free combination regimen that specifically targets HER2 is great news for these patients,” John Strickler, MD, associate professor of medicine at Duke University Medical Center, Durham, N.C., said in the press release.

Dr. Strickler was the lead investigator on the approval trial, dubbed MOUNTAINEER, which involved 84 patients who met the treatment criteria and who had also been treated with an anti-VEGF antibody. Participants whose tumors were deficient in mismatch repair proteins or were microsatellite instability–high must also have received a PD-1 inhibitor. Patients who received prior anti-HER2 therapy were excluded, the FDA explained in its own press release.

Participants were treated with tucatinib 300 mg orally twice daily– the recommended dose in product labeling – with trastuzumab administered at a loading dose of 8 mg/kg intravenously on day 1 of cycle 1 followed by a maintenance dose of trastuzumab 6 mg/kg on day 1 of each subsequent 21-day cycle.

Overall response rate was 38%, and median duration of response was 12.4 months.

The most common adverse events, occurring in at least 20% of study participants, were diarrhea, fatigue, rash, nausea, abdominal pain, infusion related reactions, and pyrexia. The most common laboratory abnormalities were increased creatinine, decreased lymphocytes, increased alanine aminotransferase, and decreased hemoglobin, among others.

Serious adverse reactions occurred in 22% of patients. The most common (occurring in ≥ 2% of patients) were intestinal obstruction (7%); urinary tract infection (3.5%); and pneumonia, abdominal pain, and rectal perforation (2.3% each). Adverse reactions leading to permanent discontinuation occurred in 6% of patients, including increased alanine aminotransferase in 2.3%.

Continued approval for the indication may be contingent upon verification and description of clinical benefit in confirmatory trials, the company said.

A global, randomized phase 3 clinical trial (MOUNTAINEER-03) is ongoing and is comparing tucatinib in combination with trastuzumab and mFOLFOX6 with standard of care and is intended to serve as a confirmatory trial, the company said.

Tucatinib is already approved in combination with trastuzumab and capecitabine for use in the treatment of advanced unresectable or metastatic HER2-positive breast cancer.

(Reuters) – President Joe Biden’s administration is urging a judge to reject a request by abortion opponents for a court order withdrawing federal approval for the drug used in medication abortions – which account for more than half of U.S. abortions – citing potential dangers to women seeking to end their pregnancies.
 

The U.S. Food and Drug Administration’s filing to U.S. District Judge Matthew Kacsmaryk, made available online on Tuesday, came in a lawsuit in Texas by antiabortion groups challenging the agency’s approval of the drug mifepristone in 2000 for medication abortion.

“The public interest would be dramatically harmed by effectively withdrawing from the marketplace a safe and effective drug that has lawfully been on the market for 22 years,” lawyers for the FDA said in the filing to Mr. Kacsmaryk, who is based in Amarillo.

Mifepristone is available under the brand name Mifeprex and as a generic. Used in conjunction with another drug, it is approved to terminate a pregnancy within the first 10 weeks of a pregnancy. The FDA on Jan. 3 said the government for the first time will allow mifepristone to be dispensed at retail pharmacies.

Medication abortion has drawn increasing attention since the U.S. Supreme Court last June overturned its landmark 1973 Roe v. Wade decision that had legalized abortion nationwide. Nearly all abortions, including medication abortions, are now banned in 12 states, and 16 states that permit some abortions also had laws restricting medication abortion as of November, according to the Guttmacher Institute, a research group that supports abortion rights.

“No abortion is safe, and chemical abortions are particularly dangerous,” said Julie Blake, senior counsel at the conservative legal group Alliance Defending Freedom, which represents the plaintiffs in the lawsuit. “The FDA, by approving chemical abortion drugs for home use, puts a woman or girl’s life at risk.”

The American College of Obstetricians and Gynecologists and the American Medical Association said in a joint letter to the Biden administration last June that “robust evidence exists regarding the safety of mifepristone for medication-induced abortion.”

Antiabortion groups including the Alliance for Hippocratic Medicine and the American Association of Pro-Life Obstetricians and Gynecologists sued the FDA in November, saying the agency improperly used an accelerated process to approve mifepristone and failed to study its risks for minors adequately.

In its court filing, the FDA said there was no basis for second-guessing the FDA’s judgment. The FDA said that pulling the drug would force patients seeking abortions in many cases to undergo unnecessary and more invasive surgical abortion. That would result in longer wait times and would carry risks for some patients including those intolerant to anesthesia, the FDA added.

In support of its position, the agency submitted declarations from abortion providers. For example, nonprofit Maine Family Planning said it would have to eliminate abortion services at 17 of its 18 clinics if mifepristone were no longer available.

Mifeprex maker Danco Laboratories on Friday also asked to intervene in the lawsuit to protect its ability to sell the drug.

“No abortion is safe, and chemical abortions are particularly dangerous,” said Julie Blake, senior counsel at the conservative legal group Alliance Defending Freedom, which represents the plaintiffs in the lawsuit. “The FDA, by approving chemical abortion drugs for home use, puts a woman or girl’s life at risk.”

The American College of Obstetricians and Gynecologists and the American Medical Association said in a joint letter to the Biden administration last June that “robust evidence exists regarding the safety of mifepristone for medication-induced abortion.”

Antiabortion groups including the Alliance for Hippocratic Medicine and the American Association of Pro-Life Obstetricians and Gynecologists sued the FDA in November, saying the agency improperly used an accelerated process to approve mifepristone and failed to study its risks for minors adequately.

In its court filing, the FDA said there was no basis for second-guessing the FDA’s judgment. The FDA said that pulling the drug would force patients seeking abortions in many cases to undergo unnecessary and more invasive surgical abortion. That would result in longer wait times and would carry risks for some patients including those intolerant to anesthesia, the FDA added.

In support of its position, the agency submitted declarations from abortion providers. For example, nonprofit Maine Family Planning said it would have to eliminate abortion services at 17 of its 18 clinics if mifepristone were no longer available.

Mifeprex maker Danco Laboratories on Friday also asked to intervene in the lawsuit to protect its ability to sell the drug.

(Reuters) – President Joe Biden’s administration is urging a judge to reject a request by abortion opponents for a court order withdrawing federal approval for the drug used in medication abortions – which account for more than half of U.S. abortions – citing potential dangers to women seeking to end their pregnancies.
 

The U.S. Food and Drug Administration’s filing to U.S. District Judge Matthew Kacsmaryk, made available online on Tuesday, came in a lawsuit in Texas by antiabortion groups challenging the agency’s approval of the drug mifepristone in 2000 for medication abortion.

“The public interest would be dramatically harmed by effectively withdrawing from the marketplace a safe and effective drug that has lawfully been on the market for 22 years,” lawyers for the FDA said in the filing to Mr. Kacsmaryk, who is based in Amarillo.

Mifepristone is available under the brand name Mifeprex and as a generic. Used in conjunction with another drug, it is approved to terminate a pregnancy within the first 10 weeks of a pregnancy. The FDA on Jan. 3 said the government for the first time will allow mifepristone to be dispensed at retail pharmacies.

The Food and Drug Administration granted accelerated approval for zanubrutinib (Brukinsa) to treat patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).

By giving the nod to these uses of this second-generation Bruton’s tyrosine kinase inhibitor, the FDA expanded on its previous approvals of this drug in mantle cell and marginal zone lymphoma.

“We have seen striking data from the Brukinsa development program demonstrating significant and consistent efficacy across CLL patient subtypes, including the high-risk del17p/TP53-mutated population, and regardless of treatment setting,” Jennifer R. Brown, MD, PhD, of Dana-Farber Cancer Institute in Boston, said in a press release from drug developer BeiGene.

The FDA’s decision was based on two phase 3 trials – SEQUOIA and ALPINE. The SEQUOIA trial assessed 479 patients with treatment-naive CLL/SLL who either received zanubrutinib until disease progression or unacceptable toxicity or bendamustine plus rituximab for six cycles. Median progression-free survival was not reached in the zanubrutinib arm and was 33.7 months in the bendamustine plus rituximab arm (hazard ratio, 0.42).

In a separate, nonrandomized SEQUOIA cohort, investigators assessed zanubrutinib in patients with a 17p deletion and found an overall response rate of 88%. In addition, over the 25-month follow-up, the median duration of response was not reached.

The ALPINE trial included 652 patients with relapsed or refractory CLL/SLL who received either zanubrutinib or ibrutinib. The overall response rate was 80% in the zanubrutinib arm versus 73% in the ibrutinib arm, and the median duration of response was not reached in either arm over the 14-month follow-up period. Median progression-free survival was not reached in the zanubrutinib arm and was 35 months in the ibrutinib group.

Dr. Brown, a lead investigator on both drug trials, suggested that, given the improvements observed in progression-free survival, zanubrutinib could become the standard of care in this setting.

In the ALPINE trial, treatment discontinuation rate was lower among patients receiving zanubrutinib (26%) versus ibrutinib (41.2%), with most discontinuations a result of adverse events or progressive disease.

And across both trials, the most common adverse reactions were decreased neutrophil count (42%), upper respiratory tract infection (39%), decreased platelet count (34%), hemorrhage (30%), and musculoskeletal pain (30%).

A vaccine database found a possible link between the Pfizer/BioNTech bivalent COVID-19 vaccine and ischemic strokes in people over 65 who got the shot, the Centers for Disease Control and Prevention and the Food and Drug Administration said in a joint news release.

The release did not recommend people change their vaccine practices, saying the database finding probably did not represent a “true clinical risk.” The CDC said everybody, including people over 65, should stay up to date on their COVID vaccines, including the bivalent booster.

The news release said the Vaccine Safety Datalink (VSD), “a near real-time surveillance system,” raised a safety concern about the Pfizer/BioNTech booster.

“Rapid-response investigation of the signal in the VSD raised a question of whether people 65 and older who have received the Pfizer-BioNTech COVID-19 Vaccine, Bivalent were more likely to have an ischemic stroke in the 21 days following vaccination compared with days 22-44 following vaccination,” the news release said.

Ischemic strokes are blockages of blood to the brain, often caused by blood clots.

“Although the totality of the data currently suggests that it is very unlikely that the signal in VSD (Vaccine Safety Datalink) represents a true clinical risk, we believe it is important to share this information with the public, as we have in the past, when one of our safety monitoring systems detects a signal,” the release said.

No higher likelihood of strokes linked to the Pfizer bivalent vaccine had been found by Pfizer/BioNTech, the Department of Veterans Affairs, the Vaccine Adverse Event Reporting System maintained by the CDC and the FDA, or other agencies that monitor reactions of vaccines, the news release said. No safety issues about strokes have been identified with the Moderna bivalent vaccine. 

CNN, citing a CDC official, reported that about 550,000 seniors who got Pfizer bivalent boosters were tracked by the VSD, and 130 of them had strokes within 3 weeks of getting the shot. None of those 130 people died, CNN said. The official spoke on the condition of anonymity because they weren’t authorized to share the data. 

The issue will be discussed at the January meeting of the FDA’s Vaccines and Related Biological Products Advisory Committee.

In a joint statement, Pfizer and BioNTech said: “Neither Pfizer and BioNTech nor the CDC or FDA have observed similar findings across numerous other monitoring systems in the U.S. and globally and there is no evidence to conclude that ischemic stroke is associated with the use of the companies’ COVID-19 vaccines.”

Bivalent boosters contain two strains of vaccine – one to protect against the original COVID-19 virus and another targeting Omicron subvariants.
