FDA panel backs adding Omicron component to COVID boosters
A federal advisory panel on June 28 recommended updating COVID-19 booster vaccines in the United States to include an Omicron component, while urging the need for more information on how well these shots work on emerging strains of the virus.
The Vaccines and Related Biological Products Advisory Committee of the Food and Drug Administration voted 19-2 in favor of a new formulation – although what that formulation will be is yet to be determined. The FDA often incorporates the views of its advisers into its decisions, although it is not bound to do so.
In this case, though, top FDA staff at the meeting seemed inclined to encourage the development of COVID vaccines modified to keep up with an evolving virus. Two Omicron subvariants, BA.4 and BA.5, which first appeared in South Africa in March 2022, have spread to the United States and have begun to increase rapidly in proportion to the virus population, the FDA said in a briefing for the meeting.
New information from the Centers for Disease Control and Prevention shows the two highly infectious subvariants now make up more than half the number of new COVID cases in the US.
Double-duty vaccine
In summarizing the message of the advisory committee, Peter W. Marks, MD, PhD, the director of the FDA’s Center for Biologics Evaluation & Research, said panelists had lent support to modifying vaccines to protect against both the original, or “ancestral” viral strain, and against Omicron, perhaps emphasizing the newly emerging subvariants.
Dr. Marks emphasized that this is a challenging decision, as no one has a “crystal ball” to forecast how SARS-CoV-2 will evolve.
“We are trying to use every last ounce of what we can from predictive modeling and from the data that we have that’s emerging, to try to get ahead of a virus that has been very crafty,” he said.”It’s pretty darn crafty.”
Limited data
Voting “no” were Paul Offit, MD, of Children’s Hospital of Philadelphia and Henry Bernstein, DO, MHCM, of Hofstra/Northwell Health in New Hyde Park, N.Y.
Both Dr. Offit and Dr. Bernstein earlier in the meeting expressed doubts about the evidence gathered to date in favor of a strain change. Dr. Offit had noted that protection seems to persist from the vaccines now available.
“To date, the current prototypical vaccines, the ancestral strain vaccines do protect against serious illness,” he said. “We don’t yet have a variant that is resistant to protection against serious illness.“
Dr. Bernstein said he was “struggling” with the question as well, given the limited data gathered to date about the vaccines and emerging strains of the virus.
Other panelists also expressed reservations, while supporting the concept of altering vaccines to teach the body to fight the emerging strains as well as the original one.
Panelist Wayne Marasco, MD, PhD, of Harvard Medical School, Boston, who voted yes, noted the difficulties of keeping up with the rapidly evolving virus, saying it’s possible that Omicron strains BA.4 and BA.5 could peak within months. That could be before the vaccines are even distributed – if all goes to plan – in the fall.
“This is a step in the right direction, but we have to reevaluate this as we move forward,” Dr. Marasco said, adding that a good strategy would be to elicit antibody response to bridge more than one variant of the virus.
Even panelists like Dr. Marasco who voted yes stressed the need for further data collection about how vaccines may be adapted to a changing virus. But they also acknowledged a need to give vaccine makers a clear indication of what the medical community expects in terms of changes to these shots.
“With the waning vaccine efficacy and the confluence of risk this fall, we need to make a move sooner rather than later and direct our sponsors in the proper direction,” said FDA panelist Michael Nelson, MD, PhD, of the University of Virginia, Charlottesville, said before the vote.

FDA panel strongly backs protein-based Novavax COVID-19 vaccine
than the cutting-edge technology used in mRNA-based shots.
The Vaccines and Related Biological Products Advisory Committee of the Food and Drug Administration voted almost unanimously June 7 in favor of Novavax’s two-dose COVID-19 vaccine for those 18 or older – despite some concerns over rare events of myocarditis and pericarditis.
The tally was 21 “yes” votes, without any “no” votes, but one abstention from a panelist who then offered a largely positive take on this vaccine.
Panelist Bruce Gellin, MD, explained at the end of the meeting that he would have cast a conditional vote in favor of the Novavax vaccine, called NVX-CoV2373, had that been an option. Dr. Gellin, chief of global public health strategy for the Rockefeller Foundation and a vaccine expert, said he didn’t want his abstention to be considered as signaling opposition to the Novavax shot.
Instead, he said, he expects FDA officials will gather more data and evidence about the Novavax vaccine, especially in relation to certain manufacturing issues, before making its decision on the company’s application.
Earlier in the day, a top FDA vaccine reviewer, Doran Fink, MD, PhD, noted that there were important manufacturing differences between the Novavax vaccine supply used in different projects, complicating efforts to assess the company’s application for emergency use authorization (EUA).
But Dr. Fink noted that the FDA staff already had made a convincing case in its briefing document, with enough evidence for an initial conditional clearance to be found in available data.
The FDA is not bound to follow the suggestions of its advisory committees but it often does.
Using the ‘bully pulpit’
At the beginning of the meeting, Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said he was seizing the “bully pulpit” in addressing the need to persuade more people in the United States to take shots against COVID-19.
About 67% of people in the United States aged 18 and older are fully vaccinated, but only about 50% of those in this group have had a first booster, according to the Centers for Disease Control and Prevention.
The two-dose mRNA vaccines from Pfizer and Moderna have been the subject of intense misinformation campaigns on social media, despite efforts by the FDA and other public health officials to convey the message about their strong benefit-risk profile. The FDA in May limited the authorized use of Johnson & Johnson’s single-dose COVID-19 shot, which is based on a different technology, because of concerns about rare and potentially life-threatening blood clots.
Novavax has been described as a more traditional vaccine – a protein subunit shot similar to one people have long received for protection against influenza, pertussis (whooping cough), diphtheria, and tetanus.
“Having a protein-based alternative may be more comfortable for some in terms of their acceptance of vaccines,” Dr. Marks said. “We do have a problem with vaccine uptake that is very serious in the United States. And anything we can do to get people more comfortable to be able to accept these potentially life-saving medical products is something that we feel we are compelled to do.”
Dr. Marks offered these remarks in answer to an FDA panelist’s question about the need to consider an EUA for yet another vaccine.
EUAs are special clearances the FDA can grant in connection with public health emergencies such as the pandemic. The FDA used EUAs for the initial December 2020 clearances of the Pfizer-BioNTech and Moderna vaccines. It has since granted normal approvals for both of these mRNA-based vaccines, based on larger bodies of evidence gathered and submitted by their developers.
During the meeting, the FDA panelists in general appeared comfortable with the idea of granting another EUA for a vaccine. There was agreement that the shot appeared to work in key tests, although these were done before the rise of the Omicron variant.
In a key test, known as study 301, the Novavax vaccine was judged to be 90.4% effective. In the study, 17 of the 17,272 people who got the Novavax vaccine developed COVID-19, compared with 79 of the 8,385 in the placebo group.
Panelists expressed disappointment with the lack of information about how the shot would work now.
“We’re looking at the efficacy against strains that don’t exist any longer,” said panelist Eric J. Rubin, MD, PhD, a Harvard professor and editor of the New England Journal of Medicine.
Still, Dr. Rubin added that he agreed with the argument the FDA’s Dr. Marks had made earlier for an EUA for the Novavax vaccine.
“If there really is a population of patients who are willing to take this and not willing to take the existing vaccines, I think it’s pretty compelling,” Dr. Rubin said.
Other FDA panelists were skeptical of this argument. Jay Portnoy, MD, who was listed on the FDA roster as the panel’s consumer representative, said he has close friends who are vaccine skeptics.
“Their hesitancy is more ideological than technological,” said Dr. Portnoy of Children’s Mercy Hospital, Kansas City, Mo. “So I really doubt that this vaccine is going to crack that nut, but perhaps some individuals would get this when they wouldn’t get the other ones.”
Myocarditis, pericarditis
The Novavax vaccine is already authorized in other countries, including Canada. Novavax in February announced that it had begun shipping its first doses of the vaccine to European Union member states. The vaccine can be moved through existing vaccine supply and cold chain channels instead of requiring complex new delivery procedures.
That could prove an advantage in time, said FDA panelist Michael Nelson, MD, PhD, of the University of Virginia, Charlottesville.
“Who knows even with supply chain challenges down the road, it will be nice to have options going forward,” Dr. Nelson said.
As with other COVID-19 vaccines, clinicians and researchers are still working to understand the potential risk for inflammation of heart muscle and nearby tissue with vaccination. Most patients with myocarditis or pericarditis who sought medical care for these conditions responded well to medicine and rest and felt better quickly, the CDC says on its website. They usually return to their normal daily activities after their symptoms improve.
At the June 7 meeting, Dr. Nelson said there may be cases of myocarditis that go undetected.
“Our signals are those who get admitted to the emergency room and the hospital,” he said. “I’m quite convinced that there are others who are experiencing cardiac events of lesser severity that are worthy of being studied, both from mechanistic and outcomes standpoints. So we have a lot of work to do.”
In looking at results for an initial pool of 40,000 people who received the Novavax vaccine, there were five reported cases of myocarditis or pericarditis developing within 20 days of people getting the shot, the FDA staff said in its presentation on safety.
In a briefing document released ahead of the advisory committee meeting, the FDA staff flagged this number of cases in a relatively small database as a concern, noting it “could be higher than reported during postauthorization use of mRNA COVID-19 vaccines (for which no cases were identified in preauthorization evaluation).”
Novavax officials took a somewhat unusual step of responding in public. The Gaithersburg, Md.–based company on June 3 issued a statement saying researchers had come to “expect to see natural background events of myocarditis in any sufficiently large database, and that young males are at higher risk.”
The data from the company’s placebo-controlled studies show that, overall, in its clinical development program, the rate of myocarditis was balanced between the vaccine and placebo arms (0.007% and 0.005%), Novavax said.
At the June 7 meeting, FDA panelists including Dr. Nelson, and Paul A. Offit, MD, of Children’s Hospital of Philadelphia, urged continued study to try to determine whether and how the vaccines could trigger myocarditis. Investments made now in pursuing these questions related to COVID-19 shots may pay off later, Dr. Offit said.
“We can use that knowledge to make safer vaccines for a disease that is going to be with us for decades, if not longer,” he said.

Regulators and the nation’s largest physician organization took separate steps in recent days to prepare for expected authorization of use of COVID-19 vaccines in children younger than age 6.
The Food and Drug Administration on May 23 announced its Vaccines and Related Biological Products Advisory Committee will meet June 15 to discuss expanding the use of COVID vaccines from Pfizer and Moderna.
The panel will examine a request from Pfizer and its partner BioNTech for an emergency use authorization (EUA) of its vaccine to cover children ages 6 months through 4 years. The EUA expansion for the Moderna shot would cover children ages 6 months through 5 years, the FDA said.
Many parents and physicians have been urging regulators to clear COVID shots for young children, among whom rates of infection are high.
The American Medical Association in February announced an update of its Current Procedural Terminology (CPT) to prepare for an eventual FDA clearance of the Pfizer-BioNTech shot for children aged 6 months to younger than 5 years. On May 19, the association announced a new CPT update to prepare for FDA clearance for use of the Moderna COVID-19 vaccine for children 6 months through 5 years.
“Extending COVID-19 vaccination protection to approximately 18 million young children will significantly reduce their risk of COVID-19 infection, hospitalization, and death, and give their parents incredible peace of mind,” Gerald Harmon, MD, AMA’s president, said in a statement. “We strongly urge all parents to get their infants and toddlers vaccinated as soon as they are eligible for a COVID-19 vaccine.”
Both the Moderna and the Pfizer-BioNTech COVID vaccines would be given to these young children in low doses.
On May 23, Pfizer announced results from a phase 2/3 trial evaluating a series of three shots of its vaccine in children ages 6 months to younger than 5 years.
Vaccine efficacy, which was a secondary endpoint in this study, was 80.3% in this age group, Pfizer said. The analysis was based on 10 symptomatic cases of COVID-19. The trial’s protocol specifies a formal analysis will be performed when at least 21 cases have accrued from 7 days after the third dose. The company said it would share final data on the effectiveness of the vaccine once the results are available.
Moderna on April 28 issued a statement with details about testing of its vaccine in young children. Vaccine efficacy was estimated at about 51% for children aged 6 months to younger than 2 years and 37% for the children aged 2 years to younger than 6. Paul Burton, MD, Moderna’s chief medical officer, spoke about this rate during a May 1 appearance on CBS’ Face the Nation.
“What it means for parents, for caregivers, is that if they give the Moderna vaccine to these little kids, they would basically cut in half the risk of that child getting symptomatic COVID,” Dr. Burton said in the interview. “Now, the number, 50%, I know is often lower than we are used to seeing with our vaccine, but it’s because this study was conducted during a time of Omicron.”
The FDA’s vaccine advisory committee also will meet on June 14 discuss potential use under an EUA of Moderna’s COVID vaccine for children and teenagers aged 6-17 years. The Pfizer-BioNTech vaccine already is authorized under an EUA for people aged 5 years and older.
The FDA has to date granted both conditional clearances, or EUAs, and regular approvals for COVID vaccines.
EUAs are meant to be temporary, allowing for rapid introduction of medicines in response to public health crises such as the pandemic. The FDA also uses EUAs to provide initial clearances of additional indications for products, as would be the case with the authorizations Moderna and Pfizer-BioNTech are seeking for their COVID vaccines.
Companies that want to continue to sell EUA-cleared products or promote EUA-cleared indications beyond the time of the public health crisis must seek regular approvals.
The FDA cleared the Pfizer-BioNTech and Moderna COVID vaccines under EUAs in December 2020. The agency then granted a regular approval for the Pfizer-BioNTech vaccine for people ages 16 and older in August 2021 based on more robust data. Regular approval for the Moderna vaccine for people ages 18 and older followed in January 2022.
Varied reactions among parents
Attitudes in the United States about pediatric COVID vaccines are far from uniform.
The initial uptake has disappointed physicians and researchers, who have been urging wider use of the COVID vaccination among children and teens for whom the FDA already has granted a clearance. Many parents are hesitating to bring their children for the COVID vaccines, according to the Centers for Disease Control and Prevention. Only 35.4% of children ages 5-11 had received at least one dose of a COVID vaccine, CDC staff said during a meeting.
Yet many other parents are demanding this medicine for their young children, urging the FDA to move quickly to clear COVID shots.
A private Facebook group called “Protect Their Future: A Call to Action for COVID Vaccines in Kids <5” boasts about 6,200 members. Many parents and physicians have used Twitter in recent months to press for a speedy review of COVID vaccines for the youngest children, often using the hashtag #immunizeunder5s. A group called Protect Their Future, which uses @ImmunizeUnder5s as its Twitter handle, had 5,288 followers as of the afternoon of May 23.
A special panel of the House of Representatives, the Select Subcommittee on the Coronavirus Crisis, on May 23 joined those tweeting about the need to soon authorize COVID vaccines for very young children.
“Parents have been waiting many months for vaccines for their young children,” the subcommittee tweeted. “They deserve to hear from @US_FDA why this lengthy process has been in children’s best interests.”

CDC signs off on COVID boosters in children ages 5-11
Centers for Disease Control and Prevention Director Rochelle Walensky, MD, signed off May 19 on an advisory panel’s recommendation that children ages 5 to 11 years should receive a Pfizer-BioNTech COVID-19 vaccine booster dose at least 5 months after completion of the primary series.
The CDC’s Advisory Committee on Immunization Practices (ACIP) voted 11:1, with one abstention, on a question about whether it recommended these additional shots in this age group.
The U.S. Food and Drug Administration on May 17 amended the emergency use authorization (EUA) for the Pfizer-BioNTech COVID-19 vaccine to cover a single booster dose for administration to individuals 5 through 11 years of age.
At the request of CDC staff, ACIP members considered whether there should be softer wording for this recommendation, stating that children in this age group “may” receive a booster. This kind of phrasing would better reflect uncertainty about the course of COVID in the months ahead and allow flexibility for a stronger recommendation in the fall.
ACIP panelists and members of key groups argued strongly for a “should” recommendation, despite the uncertainties.
They also called for stronger efforts to make sure eligible children received their initial COVID-19 shots. Data gathered between November and April show only 14.4% of children ages 5 to 11 in rural areas have received at least one dose of COVID-19 vaccination, with top rates of 39.8% in large urban communities and 36% in larger suburban regions, CDC staff said.
CDC staff also said nearly 40% of parents in rural areas reported that their children’s pediatricians did not recommend COVID-19 vaccinations, compared with only 8% of parents in urban communities. These figures concerned ACIP members and liaisons from medical associations who take part in the panel’s deliberations but not in its votes.
“People will hear the word ‘m-a-y’ as ‘m-e-h’,” said Patricia Stinchfield, RN, MS, who served as the liaison for National Association of Pediatric Nurse Practitioners to ACIP. “I think we need to add urgency” to efforts to increase use of COVID vaccinations, she said.
Voting no on Thursday was Helen Keipp Talbot, MD, of Vanderbilt University. She explained after the vote that she is in favor of having young children vaccinated, but she’s concerned about the low rates of initial uptake of the COVID-19 shots.
“Boosters are great once we’ve gotten everyone their first round,” she said. “That needs to be our priority in this.”
Sandra Fryhofer, MD, the American Medical Association’s liaison to ACIP, stressed the add-on benefits from more widespread vaccination of children against COVID. Dr. Fryhofer said she serves adults in her practice as an internal medicine physician, with many of her patients being at high risk for complications from COVID.
Too many people are assuming the spread of infections in the community has lessened the risk of the virus, Dr. Fryhofer said.
“Not everyone’s had COVID yet, and my patients will be likely to get COVID if their grandchildren get it. We’re going through pandemic fatigue in this country,” she said. “Unfortunately, masks are now more off than on. Winter’s coming. They’re more variants” of the virus likely to emerge.
The data emerging so far suggests COVID vaccines will become a three-dose medicine, as is already accepted for other shots like hepatitis B vaccine, Dr. Fryhofer said.
Data gathered to date show the vaccine decreases risk of hospitalization for COVID and for complications such as multisystem inflammatory syndrome in children (MIS-C), she said.
“The bottom line is children in this age group are getting COVID,” Dr. Fryhofer said of the 5- to 11-year-olds. “Some do fine. Some are getting real sick. Some are hospitalized, some have died.”
At the meeting, CDC staff cited data from a paper published in the New England Journal of Medicine in March showing that vaccination had reduced the risk of hospitalization for COVID-19 among children 5 to 11 years of age by two-thirds during the Omicron period; most children with critical COVID-19 were unvaccinated.
COVID-19 led to 66 deaths among children ages 5 to 11 in the October 2020 to October 2021 timeframe, said ACIP member Matthew F. Daley, MD, of Kaiser Permanente Colorado during a presentation to his fellow panel members.
Parents may underestimate children’s risk from COVID and thus hold off on vaccinations, stressed AMA President Gerald E. Harmon, MD, in a statement issued after the meeting.
“It is concerning that only 1 in 3 children between the ages of 5 and 11 in the United States have received two doses of the vaccine, in part because parents believe them to be at lower risk for severe disease than adults,” Dr. Harmon said. “But the Omicron variant brought about change that should alter that calculus.”
Responding to early data
As Dr. Fryhofer put it, the medical community has been learning in “real time” about how COVID vaccines work and how to use them.
The EUA granted on May 17 for booster shots for children ages 5 to 11 was based on an analysis of immune response data in a subset of children from an ongoing randomized placebo-controlled trial, the FDA said.
Antibody responses were evaluated in 67 study participants who received a booster dose 7 to 9 months after completing a two-dose primary series of the Pfizer-BioNTech COVID-19 Vaccine. The EUA for the booster shot was intended to respond to emerging data that suggest that vaccine effectiveness against COVID-19 wanes after the second dose of the vaccine, the FDA said.
CDC seeks help tracking vaccine complications
At the ACIP meeting, a top CDC vaccine-safety official, Tom Shimabukuro, MD, MPH, MBA, asked physicians to make sure their patients know about the agency’s V-Safe program for gathering reports from the public about their experiences with COVID vaccines. This is intended to help the CDC monitor for side effects of these medications.
“We need your help,” he said during a presentation about adverse events reported to date in children ages 5 to 11 who took the Pfizer vaccine.
About 18.1 million doses of Pfizer-BioNTech vaccine have been administered to children ages 5 to 11 years in the United States so far. Most of the reports of adverse events following vaccination were not serious, he said. But there were 20 reports of myocarditis verified to meet CDC case definition among children ages 5 to 11 years.
One case involved a death with histopathologic evidence of myocarditis on autopsy. The CDC continues to assist with case review, he said.

The EUA granted on May 17 for booster shots for children ages 5 to 11 was based on an analysis of immune response data in a subset of children from an ongoing randomized placebo-controlled trial, the FDA said.
Antibody responses were evaluated in 67 study participants who received a booster dose 7 to 9 months after completing a two-dose primary series of the Pfizer-BioNTech COVID-19 Vaccine. The EUA for the booster shot was intended to respond to emerging data that suggest that vaccine effectiveness against COVID-19 wanes after the second dose of the vaccine, the FDA said.
CDC seeks help tracking vaccine complications
At the ACIP meeting, a top CDC vaccine-safety official, Tom Shimabukuro, MD, MPH, MBA, asked physicians to make sure their patients know about the agency’s V-Safe program for gathering reports from the public about their experiences with COVID vaccines. This is intended to help the CDC monitor for side effects of these medications.
“We need your help,” he said during a presentation about adverse events reported to date in children ages 5 to 11 who took the Pfizer vaccine.
About 18.1 million doses of Pfizer-BioNTech vaccine have been administered to children ages 5 to 11 years in the United States so far. Most of the reports of adverse events following vaccination were not serious, he said. But there were 20 reports of myocarditis verified to meet CDC case definition among children ages 5 to 11 years.
One case involved a death with histopathologic evidence of myocarditis on autopsy. The CDC continues to assist with case review, he said.

CDC panel lists reasons to get second COVID booster
The Centers for Disease Control and Prevention is considering what to tell the public about second booster shots with mRNA vaccinations for COVID-19.
The U.S. Food and Drug Administration in March authorized a second booster dose of either the Pfizer-BioNTech or the Moderna COVID-19 vaccines for people aged 50 and older and certain immunocompromised adults, even though many top infectious disease experts questioned the need before the agency’s decision.
In a meeting April 20, the CDC asked its Advisory Committee on Immunization Practices to discuss second booster shots, but did not ask the group of experts to vote on formal recommendations.
Instead,
ACIP member Beth Bell, MD, MPH, of the University of Washington, Seattle, said she’s concerned about the potential for “booster fatigue.”
“A vaccination program that’s going to require boosting large proportions of the population every 4-6 months is really not sustainable and probably not something that most people want to participate in,” she said.
The benefit of additional COVID-19 shots for now appears to be smaller than what people get from the initial doses, Dr. Bell said.
Earlier in the meeting, CDC staff presented estimates about how well the COVID-19 vaccines work to prevent one case of hospitalization from the disease over 4 months among people aged 50 and older.
The major gain in preventing hospitalizations occurs with the first vaccination series and then wanes, the CDC said.
It appears that one hospitalization is prevented for every 135 people who get the first round of COVID-19 vaccinations. But it takes 674 people getting a first booster dose to prevent one hospitalization. A second booster prevents one hospitalization for every 1,205 people vaccinated.
Dr. Bell said she’s concerned about considering additional doses for “smaller and smaller return and creating an impression that we don’t have a very effective vaccination program,” even though the CDC’s data show a clear benefit.
Reasons to get a second booster
Elisha Hall, PhD, RD, of the CDC presented slides with some factors to help determine the urgency for a person to get a second booster:
- Having certain underlying medical conditions that increase the risk of severe COVID-19 illness.
- Being moderately or severely immunocompromised.
- Living with someone who is immunocompromised, at increased risk for severe disease, or who cannot be vaccinated because of age or contraindication.
- Being at increased risk of exposure to SARS-CoV-2, the virus that causes COVID-19, such as through occupational, institutional, or other activities (e.g., travel or large gatherings).
- Living or working in an area where there is a medium or high level of COVID-19 in the community.
In contrast, people might want to wait if they had been infected with SARS-CoV-2 within the past 3 months, Dr. Hall said in her presentation. Another reason for delay might be a concern that a booster dose may be more important later in the year.
The experts also addressed public confusion over boosters. For the Pfizer and Moderna mRNA vaccines, a second booster is a fourth dose, but for those who received the one-shot J&J vaccine, the second booster is a third dose.
Going forward, it may be easier to refer to subsequent doses as “annual boosters,” the CDC’s Sara Oliver, MD, MSPH, told the panel. It will be important to keep language about subsequent vaccinations clear and easy for the public to follow, she said.
Dr. Oliver also said there’s already been a drop-off in the acceptance of second rounds of COVID-19 vaccinations. CDC data show that 77% of people in the United States have had at least one dose of a COVID-19 vaccine, but only 66% of the population is fully vaccinated, and only 45% have had a first booster dose.
In her presentation, Dr. Oliver said the top priority in COVID-19 vaccination efforts remains initial vaccinations for people who haven’t gotten them.
Kids younger than 5
During the public comment session of the CDC meeting, several people called on the FDA to move quickly to expand authorization of COVID-19 vaccines to children aged 5 years and younger.
“We know that many parents and caregivers and health care providers are anxious to have COVID vaccines available” for young children, said Doran Fink, MD, PhD, a deputy director of the FDA’s vaccines division.
He said the agency is working to be ready to authorize the shots for young children while it awaits research results from the manufacturers.

Norovirus vaccine candidates employ different approaches
Scientists are trying different approaches to developing vaccines against norovirus, seeking to replicate the success seen in developing shots against rotavirus.
Speaking at the 12th World Congress of the World Society for Pediatric Infectious Diseases (WSPID), Miguel O’Ryan, MD, of the University of Chile, Santiago, presented an overview of candidate vaccines. Dr. O’Ryan has been involved for many years with research on rotavirus vaccines and has branched into work with the somewhat similar norovirus.
With advances in preventing rotavirus, norovirus has emerged in recent years as a leading cause of acute gastroenteritis (AGE) in most countries worldwide. It’s associated with almost 20% of all acute diarrheal cases globally and with an estimated 685 million episodes and 212,000 deaths annually, Dr. O’Ryan and coauthors reported in a review in the journal Viruses.
If successful, norovirus vaccines may be used someday to prevent outbreaks among military personnel, as this contagious virus has the potential to disrupt missions, Dr. O’Ryan and coauthors wrote. They also said people might consider getting norovirus vaccines ahead of trips to prevent traveler’s diarrhea. But most importantly, these kinds of vaccines could reduce diarrhea-associated hospitalizations and deaths of children.
Takeda Pharmaceutical Company, for whom Dr. O’Ryan has done consulting, last year announced a collaboration with Frazier Healthcare Partners to launch HilleVax. Based in Boston, the company is intended to commercialize Takeda’s norovirus vaccine candidate.
The Takeda-HilleVax candidate vaccine injection has advanced as far as phase 2 studies, including a test done over two winter seasons in U.S. Navy recruits. Takeda and U.S. Navy scientists reported in 2020 in the journal Vaccine that the primary efficacy outcome for this test could not be evaluated due to an unexpectedly low number of cases of norovirus. Still, data taken from this study indicate that the vaccine induces a broad immune response, the scientists reported.
In his WSPID presentation, Dr. O’Ryan also mentioned an oral norovirus vaccine candidate that the company Vaxart is developing, referring to this as a “very interesting approach.”
Betting on the gut
Based in South San Francisco, California, Vaxart is pursuing a theory that a vaccine designed to generate mucosal antibodies locally in the intestine, in addition to systemic antibodies in the blood, may better protect against norovirus infection than an injectable vaccine.
“A key ability to protect against norovirus needs to come from an intestinal immune response, and injected vaccines don’t give those very well,” Sean Tucker, PhD, the founder and chief scientific officer of Vaxart, told this news organization in an interview. “We think that’s one of the reasons why our oral approaches can have significant advantages.”
Challenges to developing a norovirus vaccine have included a lack of good animal models to use in research and a lack of an ability to grow the virus well in cell culture, Dr. Tucker said.
Vaxart experienced disruptions in its research during the early stages of the pandemic but has since picked up the pace of its efforts to develop its oral vaccine, Dr. Tucker said during the interview.
In a recent filing with the Securities and Exchange Commission, Vaxart said in early 2021 it resumed its norovirus vaccine program by initiating three clinical studies. These included a phase 1b placebo-controlled dose ranging study in healthy elderly adults aged 55-80. Data from these trials may be unveiled in the coming months.
Vaxart said that this year it has already initiated a phase 2 norovirus challenge study, which will evaluate safety, immunogenicity, and clinical efficacy of a vaccine candidate against placebo.

FDA, DEA pushed to make gabapentin a controlled substance to stop ‘widespread misuse’
In a bid to stop abuse and diversion of the anticonvulsant gabapentin, a watchdog group is petitioning federal regulators to make the drug a controlled substance.
Gabapentin is a generic drug, best known under the brand name Neurontin. The petition also covers the related drug gabapentin enacarbil (Horizant).
Public Citizen requested that gabapentin come under the DEA’s Schedule V category, which already includes the similar drug pregabalin (Lyrica). Schedule V is the lowest rung on the DEA’s drug schedule, meaning it has lower potential for abuse then Schedule I through IV drugs. This tier also includes cough preparations with less than 200 milligrams of codeine.
Classifying gabapentin as a Schedule V drug would facilitate better tracking of the drug’s use and misuse and put in place educational and limitation requirements to mitigate the risk of addiction, overdose, and death, Michael Abrams, MPH, PhD, senior health researcher with Public Citizen’s Health Research Group, and colleagues write in the petition.
‘Widespread misuse’
There is “substantial evidence of widespread misuse” of gabapentin, plausibly helped by “extraordinary levels of off-label prescribing,” Public Citizen said in the petition.
Some estimates have pegged off-label use at more than 90%, with gabapentin prescribed for indications such as chronic cough, hiccups, postoperative pain, and postmenopausal hot flashes, the group said.
“Moreover, there are numerous reports indicating that gabapentin is widely used and diverted on the street to induce ‘highs’ or otherwise self-medicate,” Public Citizen said. “Both gabapentin and pregabalin have been empirically linked to the opioid overdose epidemic as drugs that potentiate the activity of these oftentimes deadly analgesics.”
This news organization tried several times to reach Azurity for comment but did not receive a response. Pfizer included gabapentin in the portfolio of drugs used to create the Viatris spin-off, which took place in 2020. Pfizer referred this news organization to Viatris for comment, but it also did not respond.
It is unclear how the FDA and DEA will respond to the petition. Public Citizen has received a reply from the FDA, in which the agency acknowledged receipt of the petition. However, the “acceptance of the petition for filing is a procedural matter and in no way reflects the agency’s decision on the substantive merits of the petition,” the FDA said in a letter.
As is common practice, the agency assigned a docket number for the petition, FDA-2022-P-0149. The docket’s website allows interested parties to track the issue.
‘Unnoticed’ abuse
There have been rising concerns about risks and abuse of gabapentin in recent years. In its petition, Public Citizen noted that the United Kingdom and several U.S. states have already sought tighter control of gabapentin prescriptions.
In 2019, the United Kingdom announced it would reclassify both pregabalin and gabapentin as class C controlled substances because of the rising numbers of deaths linked to the drugs.
As of November 2020, seven states – Alabama, Kentucky, Michigan, North Dakota, Tennessee, Virginia, and West Virginia – had classified gabapentin as a schedule V drug, while another 12 states required prescription monitoring of the drug, Public Citizen noted.
In 2018, researchers at the University of Louisville, Kentucky, a state that has been hit particularly hard by the opioid crisis, tried to draw more attention to the risks of gabapentin.
“Amid the opioid epidemic, abuse of a different prescription painkiller has widely gone unnoticed,” the University said in a press release at the time.
The release highlighted a study led by Rachel Vickers Smith, PhD, assistant professor in the University of Louisville School of Nursing that was published in Psychology of Addictive Behaviors.
It included 33 individuals who reported recent recreational use of gabapentin. Use of the drug was combined with buprenorphine, other opioids, cocaine, and caffeine to produce effects such as muscle relaxation, pain reduction, sleep induction, feeling drunk, and feeling “high.”
In the press release, Dr. Vickers Smith said individuals who abuse gabapentin often mix it with opioids, marijuana, cocaine, and opioid treatment medication, compounding side effects to the central nervous system that include euphoria and sedation.
In addition, some individuals who primarily abused opioid pain medication have turned to gabapentin after law-enforcement actions made it more difficult to obtain prescription opioids, she noted.
“People are looking for other drugs to substitute for opioids, and gabapentin has filled that place for some,” Dr. Vickers Smith said. “Some have said it gives them a high similar to opioids.”
FDA 2019 warning
In 2019, the FDA issued a warning about serious breathing difficulties associated with gabapentin and pregabalin in patients with respiratory risk factors.
These factors include opioid use and other drugs that depress the central nervous system, as well as conditions such as chronic obstructive pulmonary disease that reduce lung function. Older patients are also at higher risk, the FDA said.
The agency noted that gabapentinoids are often co-prescribed with opioids for for medical conditions and abused in combination with opioids. Data collected in 2016 from an office-based physician survey showed 14% of patient encounters involving gabapentin also involved opioids, the FDA said.
“Our evaluation shows that the use of these medicines, often referred to as gabapentinoids, has been growing for prescribed medical use, as well as misuse and abuse,” the agency said in its 2019 alert.

“People are looking for other drugs to substitute for opioids, and gabapentin has filled that place for some,” Dr. Vickers Smith said. “Some have said it gives them a high similar to opioids.”
FDA 2019 warning
In 2019, the FDA issued a warning about serious breathing difficulties associated with gabapentin and pregabalin in patients with respiratory risk factors.
These factors include opioid use and other drugs that depress the central nervous system, as well as conditions such as chronic obstructive pulmonary disease that reduce lung function. Older patients are also at higher risk, the FDA said.
The agency noted that gabapentinoids are often co-prescribed with opioids for for medical conditions and abused in combination with opioids. Data collected in 2016 from an office-based physician survey showed 14% of patient encounters involving gabapentin also involved opioids, the FDA said.
“Our evaluation shows that the use of these medicines, often referred to as gabapentinoids, has been growing for prescribed medical use, as well as misuse and abuse,” the agency said in its 2019 alert.

In a bid to stop abuse and diversion of the anticonvulsant gabapentin, a watchdog group is petitioning federal regulators to make the drug a controlled substance.
Gabapentin is a generic drug, best known under the brand name Neurontin. The petition also covers the related drug gabapentin enacarbil (Horizant).
Public Citizen requested that gabapentin come under the DEA’s Schedule V category, which already includes the similar drug pregabalin (Lyrica). Schedule V is the lowest rung on the DEA’s drug schedule, meaning it has lower potential for abuse then Schedule I through IV drugs. This tier also includes cough preparations with less than 200 milligrams of codeine.
Classifying gabapentin as a Schedule V drug would facilitate better tracking of the drug’s use and misuse and put in place educational and limitation requirements to mitigate the risk of addiction, overdose, and death, Michael Abrams, MPH, PhD, senior health researcher with Public Citizen’s Health Research Group, and colleagues write in the petition.
‘Widespread misuse’
There is “substantial evidence of widespread misuse” of gabapentin, plausibly helped by “extraordinary levels of off-label prescribing,” Public Citizen said in the petition.
Some estimates have pegged off-label use at more than 90%, with gabapentin prescribed for indications such as chronic cough, hiccups, postoperative pain, and postmenopausal hot flashes, the group said.
“Moreover, there are numerous reports indicating that gabapentin is widely used and diverted on the street to induce ‘highs’ or otherwise self-medicate,” Public Citizen said. “Both gabapentin and pregabalin have been empirically linked to the opioid overdose epidemic as drugs that potentiate the activity of these oftentimes deadly analgesics.”
This news organization tried several times to reach Azurity for comment but did not receive a response. Pfizer included gabapentin in the portfolio of drugs used to create the Viatris spin-off, which took place in 2020. Pfizer referred this news organization to Viatris for comment, but it also did not respond.
It is unclear how the FDA and DEA will respond to the petition. Public Citizen has received a reply from the FDA, in which the agency acknowledged receipt of the petition. However, the “acceptance of the petition for filing is a procedural matter and in no way reflects the agency’s decision on the substantive merits of the petition,” the FDA said in a letter.
As is common practice, the agency assigned a docket number for the petition, FDA-2022-P-0149. The docket’s website allows interested parties to track the issue.
‘Unnoticed’ abuse
There have been rising concerns about risks and abuse of gabapentin in recent years. In its petition, Public Citizen noted that the United Kingdom and several U.S. states have already sought tighter control of gabapentin prescriptions.
In 2019, the United Kingdom announced it would reclassify both pregabalin and gabapentin as class C controlled substances because of the rising numbers of deaths linked to the drugs.
As of November 2020, seven states – Alabama, Kentucky, Michigan, North Dakota, Tennessee, Virginia, and West Virginia – had classified gabapentin as a schedule V drug, while another 12 states required prescription monitoring of the drug, Public Citizen noted.
In 2018, researchers at the University of Louisville, Kentucky, a state that has been hit particularly hard by the opioid crisis, tried to draw more attention to the risks of gabapentin.
“Amid the opioid epidemic, abuse of a different prescription painkiller has widely gone unnoticed,” the University said in a press release at the time.
The release highlighted a study led by Rachel Vickers Smith, PhD, assistant professor in the University of Louisville School of Nursing that was published in Psychology of Addictive Behaviors.
It included 33 individuals who reported recent recreational use of gabapentin. Use of the drug was combined with buprenorphine, other opioids, cocaine, and caffeine to produce effects such as muscle relaxation, pain reduction, sleep induction, feeling drunk, and feeling “high.”
In the press release, Dr. Vickers Smith said individuals who abuse gabapentin often mix it with opioids, marijuana, cocaine, and opioid treatment medication, compounding side effects to the central nervous system that include euphoria and sedation.
In addition, some individuals who primarily abused opioid pain medication have turned to gabapentin after law-enforcement actions made it more difficult to obtain prescription opioids, she noted.

Clozapine interrupted: APA, others seek FDA forum on REMS
In a Feb. 14 letter, the groups asked the FDA to reconsider its new risk evaluation and mitigation strategy (REMS) for clozapine because of concerns it had the potential to cause abrupt discontinuation of the medication.
The groups cite an Institute for Safe Medication Practices (ISMP) report of a 40-year-old woman who was a long-time clozapine user, had a cardiac arrest, and died after she stopped taking the drug because her psychiatrist was unable to register for the updated version of the REMS.
“It is unacceptable for a REMS with unproven effectiveness at meeting its goal to carry risks of interruptions that can result in rehospitalization, acute exacerbation of psychosis, increased risk of suicide, and potentially fatal orthostatic hypotension/bradycardic syndromes associated with incorrect restarts,” the groups said in the letter.
“We feel certain that this case reported in the literature is not the only serious adverse outcome from the REMS and the transition,” they added.
The letter was signed by the American Psychiatric Association, the American Association for Community Psychiatry, the American Psychiatric Nurses Association, the College of Psychiatric and Neurologic Pharmacists, the National Alliance on Mental Illness, the National Association of State Mental Health Program Directors, and the National Council for Mental Wellbeing.
Clozapine can decrease the neutrophil count, which can lead to severe neutropenia, serious infection, and death. Consequently, the FDA put additional safety measures in place governing clozapine prescribing.
In 2015, a centralized clozapine REMS replaced separate prescribing registries that the drug manufacturers maintained. There were technical issues with the 2015 start-up of that website, including data migration problems and long call wait times, the FDA said.
Subsequently, the drug’s manufacturers then decided to change the REMS platform, which created new issues that led to high call volume and long wait times for clinicians and pharmacists who were trying to enroll.
Maintaining access
In November 2021, the FDA announced it would put some aspects of a planned switch on hold. A month later, the agency made further modifications to its plan.
The FDA said it would exercise “enforcement discretion” to try to maintain access to clozapine amid hitches with the REMS transition efforts. The agency also said at the time that it would not object if pharmacists dispensed clozapine without the usual authorization. In addition, wholesalers could ship the drug to pharmacies and health care settings without confirming REMS enrollment.
The FDA also held two December meetings to allow various stakeholders to air concerns.
In their letter, the APA and other groups asked if the FDA intends to continue with accommodations, such as allowing pharmacies to order clozapine from wholesalers without restriction.
“We do not feel the issues are resolved,” the groups said.

High praise, condemnation for CMS Aduhelm coverage plan
Medicare has received a key endorsement of its plan to restrict payment for the controversial Alzheimer’s disease (AD) drug aducanumab (Aduhelm) – but also drew pleas from other groups for more generous reimbursement of the drug, as well as expected similar medications currently in development.
The Centers for Medicare & Medicaid Services received more than 9,900 comments on its plan, according to the current tally posted on its website. However, it is unclear when the final count will be available.
CMS intends to limit federal payment for monoclonal antibodies that target amyloid to clinical trials. Among supporters of this approach is the influential Medicare Payment Advisory Commission, an expert panel that helps Congress and CMS manage the federal health program.
Opponents of the CMS plan include several pharmaceutical companies. Patient and consumer groups, individuals, and lawmakers had mixed views.
CMS officials will weigh the feedback provided in the comments when setting a final coverage policy for aducanumab. It is expected the agency’s final decision will be announced on April 11.
Ongoing debate
The Food and Drug Administration’s unusual approach to clearing the drug for U.S. sales triggered a review of its management of the accelerated approval process by the Office of Inspector General for the Department of Health & Human Services.
The FDA granted an accelerated approval for aducanumab in June based on evidence that the drug clears amyloid in the brain. However, it is unclear whether clearing the protein from the brain results in clinical benefit.
Usually, accelerated approvals precede the completion of phase 3 drug trials, with the FDA allowing early access to a medicine while awaiting confirmatory trials.
In the case of aducanumab, results of the phase 3 confirmatory trials ENGAGE and EMERGE were available at the time of FDA approval. However, interpretation of the findings is controversial.
Biogen contends that the amyloid-clearing effect of the higher dose of aducanumab shown in EMERGE indicates the drug has clinical potential. However, others argue that amyloid clearance does not indicate clinical benefit.
Limiting Medicare coverage of aducanumab for treatment of AD means “the progression of disease, for nearly all beneficiaries, would continue unabated,” Biogen wrote in its comment to CMS.
Conflicting data
Supporters of the CMS plan have a different view of the trial data. They note the failure of aducanumab in the companion ENGAGE trial, while also questioning the magnitude of benefit suggested by even the most positive data cited for the drug in the EMERGE trial.
Both studies used the Clinical Dementia Rating-Sum of Boxes (CDR-SB) score, an 18-point scale measuring cognition and function.
In his comment to CMS, MedPAC chairman Michael E. Chernew, PhD, noted the change in CDR-SB score of 0.39 in EMERGE’s high-dose aducanumab group. CMS has described this as being “less than the 1-2 point change that has been suggested as a minimal clinically important difference,” Dr. Chernew wrote.
MedPAC does not normally comment on Medicare coverage decisions, but did so in this case because of its significance and because of the potential fiscal implications, he noted.
“Though there is only limited, conflicting data on Aduhelm’s clinical effectiveness, Medicare would pay a high price for the product,” Dr. Chernew wrote, pointing out the $28,200 annual U.S. price of the drug.
MedPAC thus endorsed the coverage-with-evidence-development (CED) pathway. Under this approach, Medicare would pay for these drugs when used in clinical trials that meet certain criteria.
Legal challenge?
In its comment to CMS, Biogen questioned the agency’s legal grounds for limiting coverage of aducanumab. A mandate on clinical trials as part of the CED proposal “runs afoul of the Administrative Procedure Act’s prohibition against arbitrary and capricious agency action,” Biogen said.
The drug company argued that its own planned follow-on studies would provide the kind of data Medicare officials want to see. It also argued for greater use of observational data, including real-world evidence, and of information from Medicare claims.
Roche’s Genentech, which is also developing antiamyloid drugs for AD, echoed some of Biogen’s concerns about the aducanumab plan.
CMS’ CED plan would be “unnecessarily restrictive and discouraging for patients living with this destructive disease,” David Burt, executive director for federal government affairs at Genentech, wrote in a comment to CMS.
CMS should clarify that the CED requirement would not apply to cases of FDA-approved antiamyloid therapies that have demonstrated “clinically meaningful improvement,” Mr. Burt added. He noted there are phase 3 trials of drugs in this class that could soon produce data.
CMS should “fully consider the broad ramifications and significant unintended consequences of prematurely placing unduly severe restrictions on the entire class of antiamyloid monoclonal antibodies,” Mr. Burt wrote.
Health care inequity
In its comment to CMS, Biogen also noted the Medicare proposal would “compound the already pervasive inequities in access to treatment and will ultimately prove highly detrimental to health equity.”
There are already concerns about the access of Black and Latinx patients to clinical trials. The planned CED approach would tightly restrict access to aducanumab, as well as expected follow-ons in the amyloid-directed monoclonal antibody (mAb) drug class, the company said.
“Many of the trial sites for Aduhelm, as well as for other amyloid-directed [monoclonal antibodies] are not hospital-based outpatient settings, but include infusion centers, private practices, and medical research centers,” Biogen wrote.
Patient groups such as UsAgainstAlzheimer’s told CMS the CED approach would worsen disparities, despite the aim of Medicare officials to increase participation of Black and Latinx patients in future testing.
“CMS will be hard-pressed to achieve diversity if such hospitals are the only locations where Medicare beneficiaries are able to access mAbs,” USAgainstAlzheimer’s wrote in a Feb. 10 comment.
In contrast, the nonprofit National Center for Health Research praised CMS for what it described as an effort to address a lack of representation of Black and Latinx patients in earlier aducanumab research.
However, the NCHR also suggested CMS revise its plan to mandate that clinical trials include patients who are representative of the national population diagnosed with AD.
“Rather than being concerned about the percentage of patients in specific racial and ethnic groups, we propose that CMS include sufficient numbers of patients in different racial, ethnic, and age groups to ensure that there is enough statistical power for subgroup analyses to determine safety and efficacy for each of the major demographic groups,” the NCHR wrote.
Patient health, Medicare at risk
On Feb. 8, a group of House Republican lawmakers asked CMS to reverse its stance. In a publicly released letter, Rep. Cathy McMorris Rodgers of Washington state, the ranking Republican on the House Energy and Commerce Committee, and colleagues urged broader coverage of aducanumab.
In the letter, the group emphasized the idea of aducanumab as a potential treatment for patients with Down syndrome who are at risk for AD.
“The link between Down Syndrome and AD is still being researched by scientists,” Rep. Rodgers and colleagues wrote.
“However, there appears to be a correlation between the additional 21st chromosome present in people with Down Syndrome and the chromosome’s gene that makes amyloid precursor proteins and can cause a build-up of the beta-amyloid plaques common amongst those with AD,” they add.
On the other hand, CMS garnered earlier support from influential Democrats. On Jan. 13, House Energy and Commerce Chairman Frank Pallone Jr (D-N.J.) and House Oversight and Reform Chairwoman Carolyn B. Maloney (D-N.Y.) released a letter praising CMS for its plan for covering aducanumab.
In addition to the HHS-OIG review of the FDA’s approval of the drug, the two House committees are in the midst of their own investigation of the agency’s decision to clear the drug.
“Any broader coverage determination before there is clarity on Aduhelm’s approval process and findings from the myriad ongoing investigations may put the health of millions of Alzheimer’s patients on the line and the financial stability of the nation’s health insurance program for American seniors at risk,” Rep. Pallone and Rep. Maloney wrote.

There are already concerns about the access of Black and Latinx patients to clinical trials. The planned CED approach would tightly restrict access to aducanumab, as well as expected follow-ons in the amyloid-directed monoclonal antibody (mAb) drug class, the company said.
“Many of the trial sites for Aduhelm, as well as for other amyloid-directed [monoclonal antibodies] are not hospital-based outpatient settings, but include infusion centers, private practices, and medical research centers,” Biogen wrote.
Patient groups such as UsAgainstAlzheimer’s told CMS the CED approach would worsen disparities, despite the aim of Medicare officials to increase participation of Black and Latinx patients in future testing.
“CMS will be hard-pressed to achieve diversity if such hospitals are the only locations where Medicare beneficiaries are able to access mAbs,” USAgainstAlzheimer’s wrote in a Feb. 10 comment.
In contrast, the nonprofit National Center for Health Research praised CMS for what it described as an effort to address a lack of representation of Black and Latinx patients in earlier aducanumab research.
However, the NCHR also suggested CMS revise its plan to mandate that clinical trials include patients who are representative of the national population diagnosed with AD.
“Rather than being concerned about the percentage of patients in specific racial and ethnic groups, we propose that CMS include sufficient numbers of patients in different racial, ethnic, and age groups to ensure that there is enough statistical power for subgroup analyses to determine safety and efficacy for each of the major demographic groups,” the NCHR wrote.
Patient health, Medicare at risk
On Feb. 8, a group of House Republican lawmakers asked CMS to reverse its stance. In a publicly released letter, Rep. Cathy McMorris Rodgers of Washington state, the ranking Republican on the House Energy and Commerce Committee, and colleagues urged broader coverage of aducanumab.
In the letter, the group emphasized the idea of aducanumab as a potential treatment for patients with Down syndrome who are at risk for AD.
“The link between Down Syndrome and AD is still being researched by scientists,” Rep. Rodgers and colleagues wrote.
“However, there appears to be a correlation between the additional 21st chromosome present in people with Down Syndrome and the chromosome’s gene that makes amyloid precursor proteins and can cause a build-up of the beta-amyloid plaques common amongst those with AD,” they add.
On the other hand, CMS garnered earlier support from influential Democrats. On Jan. 13, House Energy and Commerce Chairman Frank Pallone Jr (D-N.J.) and House Oversight and Reform Chairwoman Carolyn B. Maloney (D-N.Y.) released a letter praising CMS for its plan for covering aducanumab.
In addition to the HHS-OIG review of the FDA’s approval of the drug, the two House committees are in the midst of their own investigation of the agency’s decision to clear the drug.
“Any broader coverage determination before there is clarity on Aduhelm’s approval process and findings from the myriad ongoing investigations may put the health of millions of Alzheimer’s patients on the line and the financial stability of the nation’s health insurance program for American seniors at risk,” Rep. Pallone and Rep. Maloney wrote.

Biden’s FDA chief nominee narrowly wins Senate confirmation
On Feb. 15, Robert Califf, MD, narrowly won Senate confirmation to once again serve as the commissioner of the Food and Drug Administration, overcoming protest votes from lawmakers about abortion and opioid issues.
The Senate voted 50-46 in favor of Dr. Califf’s nomination. A cardiologist long affiliated with Duke University and a noted expert on clinical trials, Dr. Califf also led the FDA from February 2016 through January 2017.
In 2016, the Senate confirmed him as FDA chief in an 89-4 vote. At that time, Sen. Joe Manchin, D-WV, and a few other senators said they were concerned that Dr. Califf’s links to the drug industry would hamper his ability to regulate drugmakers, particularly in terms of rules on prescription painkillers.
Sen. Manchin also objected to Dr. Califf’s second nomination as FDA commissioner, as did several fellow Democrats, including Sen. Edward Markey of Massachusetts. In a statement issued after the Feb. 15 vote, Sen. Markey said he has “consistently raised concerns about the FDA’s egregious mishandling of opioid approvals and its role in enabling the current opioid epidemic.”
“To date, the FDA still has not implemented many of the reforms necessary to ensure that it is fulfilling its role as our nation’s top pharmaceutical cop on the beat,” Sen. Markey said. “I have not received any real commitment from Dr. Califf to truly reform the FDA or to learn from the failures that fueled this public health crisis.”
This time, Dr. Califf lost support among Republican senators due to objections raised by groups seeking to end women’s access to abortion. Susan B. Anthony List and National Right to Life asked senators in a January letter to oppose Dr. Califf’s nomination, citing their objections to how the FDA handled reporting of adverse events from abortions by medication during Dr. Califf’s Tenure.
But some Republicans supported Califf in the Tuesday vote. Sens. Roy Blunt of Missouri, Richard Burr of North Carolina, Susan Collins of Maine, Lisa Murkowski of Alaska, Mitt Romney of Utah, and Pat Toomey of Pennsylvania all voted in his favor.
On Feb. 14, Sen. Patty Murray, D-WA, chairwoman of the Senate Health, Education, Labor, and Pensions Committee, urged her colleagues to vote for Dr. Califf to give the FDA strong leadership to tackle urgent health needs such as the opioid crisis, youth tobacco use, antimicrobial resistance, and inequities in health care.
“At this critical moment, we need a trusted hand to lead the FDA,” she said in a floor speech. Dr. Califf’s previous service at the FDA and his years spent as a research scientist “give him the experience to take on this challenge.”
Separately, three former FDA commissioners on Feb. 15 published an opinion article that appeared in The Hill. Republican presidents nominated two of these former FDA chiefs: Scott Gottlieb, MD, and Mark McClellan, MD. The third, Margaret Hamburg, MD, was nominated by President Barack Obama, as was Dr. Califf for his first time as FDA chief.
There’s an urgent need for a confirmed leader at the FDA as the United States seeks to move beyond the pandemic, the former FDA chiefs wrote. The work ahead includes continued efforts with vaccines as well as efforts to bolster medical supply chains, they said.
Dr. Califf “knows how to advance the safe development and use of medical products and to bring a sound, science-based foundation to the FDA’s regulatory actions. Because of this, he has earned the confidence of FDA’s professional career staff, as well as a broad base of patient groups, academic experts, medical professionals, and public health organizations,” Dr. Gottlieb, Dr. Hamburg, and Dr. McClellan wrote.
The article also was signed by former Centers for Medicare and Medicaid Services Administrator Andy Slavitt, who served in the Obama administration.
Support of medical community
The American Heart Association issued a statement on Feb.15, congratulating Dr. Califf on his second confirmation after the Senate vote.
“With a distinguished career in public service and a long-time volunteer leader at the American Heart Association, Dr. Califf has honed his ability to communicate and build trust with diverse constituencies,” CEO Nancy Brown said in the statement. “He will use his experience as a cardiologist to safeguard the health and well-being of people throughout the country, and his background in research to prioritize science and evidence-based policymaking.”
Dr. Califf was also backed by the Association of American Medical Colleges, the American Academy of Pediatrics, the American Academy of Family Physicians, and the American College of Physicians when he was nominated for the role last year by President Joe Biden.
