President Biden has yet to nominate a permanent head of the Food and Drug Administration (FDA) at a time when the government is navigating a surge in COVID-19 cases from the delta variant.

It’s unclear why the post remains vacant more than six months into Biden’s presidency, but some experts suggest politics may be getting in the way.

Some Democratic senators are pushing back on the prospects of acting Commissioner Janet Woodcock being named to the permanent role, but health care experts are warning that the administration needs to fill the position immediately.

Biden selected Woodcock, a longtime FDA regulator, to serve as the acting commissioner in January but has since received pushback, including from senators and anti-opioid advocates on that move.

Several Democratic senators have voiced opposition to Woodcock, citing her time at the FDA when opioid painkillers were approved, later contributing to an epidemic that has left many Americans dead.

“I continue to have concerns about Dr. Woodcock as a potential permanent FDA Commissioner, especially given the role she played in approving and labeling opioid-based medications,” Sen. Maggie Hassan (D-N.H.), a member of the Senate Health, Education, Labor and Pensions Committee, said in a statement. “That’s why I’ve called on President Biden to put forward an FDA commissioner who will act independently from the industry that he or she regulates.”

Sen. Joe Manchin (D-W.Va.), a centrist, has also called on the administration to prioritize nominating a different commissioner, citing concerns about the opioid epidemic and the FDA’s controversial approval of the Alzheimer’s drug Aduhelm.

“Dr. Woodcock is not the right person to lead the FDA,” he wrote in a June letter to Biden.

Two months earlier, Sen. Catherine Cortez Masto (D-Nev.) vowed to oppose a potential Woodcock nomination.

Her prospects have not improved over the summer.

In a statement, Sen. Ed Markey (D-Mass.) called for a “permanent, qualified, trusted” commissioner to address the pandemic and opioid epidemic. Without specifically mentioning Woodcock, he said, “The FDA needs a leader who will learn from the agency’s past mistakes to ensure it never makes them again.”

Other names floated for commissioner include Zeke Emanuel, former health policy adviser in the Obama administration and an architect of the 2010 Affordable Care Act; Michelle McMurry-Heath, CEO of the Biotechnology Innovation Organization; Katherine Luzuriaga, director of the University of Massachusetts Center for Clinical and Translational Science; and Florence Houn, who worked at the FDA during multiple administrations.

Some experts emphasized that it’s more important to get the right nominee than to rush one through the Senate.

“It’s taken the administration rather a long time to make a decision,” said Diana Zuckerman, president of the National Center for Health Research. “It makes it even more important that they make the right decision, not just be pushed into making a decision in the next X number of weeks or months.”

Zuckerman called for the Biden administration to prioritize choosing a nominee with a “very strong public health perspective,” noting that Woodcock has become an “untenable” candidate amid the opposition and “controversial” decisions at the agency during her tenure, which dates back to 1986.

FDA Scrutinizes Pricey Cancer Drugs

Politico Pulse: April 28, 2021

What should be done about expensive cancer drugs on the market that might not work? That could be the first thorny question to confront Woodcock, who is acting FDA commissioner while Biden weighs whether to nominate her for the full-time role.

The FDA is convening an expert panel this week to discuss whether the agency should revoke approved uses of three therapies that, despite positive signs from early research, failed to help patients with certain cancers live longer. All three medicines were approved under Woodcock’s tenure as drug chief and after increasingly speedy reviews.

Drug regulators “wanted to get these drugs to market as quickly as possible,” said Diana Zuckerman, a drug safety expert and president of the National Center for Health Research, who is presenting several times at this week’s meeting. “That was clearly their goal and they succeeded in doing it. But now there is a reckoning.”

What the companies say: Genentech, Merck and Bristol-Myers Squibb, the companies at the center of the debate, say their drugs still have value against the cancers in question, they just need to do more research. And Genentech on Tuesday applauded the advisory panel’s vote to keep its drug on the market for triple-negative breast cancer, one of the approvals in question.

Janet Woodcock revolutionized the way the FDA reviews cancer drugs, inspiring her supporters and raising concerns for detractors

Cost, In the News, News Stories & Editorials, We're In the News, , , , ,

Nicholas Florko, STAT News: March 1, 2021

In 2000, the Food and Drug Administration approved just three cancer drugs. Last year, even with the agency laser-focused on the coronavirus pandemic, much of its staff teleworking, the agency still approved a record-breaking 17 different cancer therapies — more than in any other category. That’s the legacy of FDA drug center chief Janet Woodcock. Woodcock, a 36-year veteran of the agency, is infamous for pushing the FDA to loosen its standards for drugs for rare conditions like Duchenne muscular dystrophy. But Woodcock’s most lasting impact at the FDA is her transformation of the way the agency approaches cancer drug approvals….. Now the nation’s top cancer doctors are emerging as Woodcock’s most vocal backers in her campaign to become President Biden’s FDA commissioner.

Critics say Woodcock’s cancer crusade has come at a cost. With the speed has come an erosion of the agency’s high standards and an increasing willingness to greenlight drugs that haven’t actually been proven to extend a patient’s life. … Their complaint mostly revolves around Woodcock’s willingness to accept studies testing drugs based on so-called surrogate endpoints, measures like the shrinkage of a tumor, rather testing a drug based on how long it keeps a patient alive. ….It’s a view that even some former FDA officials hold; one described Woodcock as pushing “flexibility even at the expense of science.”

“For many cancers there is an improvement in survival, the question is which drugs are responsible for that and which ones aren’t, that’s the big unknown and that’s what’s so frustrating,” said Diana Zuckerman, the president of the National Center for Health Research. The end result of this confusion, critics argue, is that doctors and patients are left guessing whether a drug is truly effective, or worth the money.

HEALTH CARE BRIEFING: FDA Vaccine Rules Challenged as Weak

In the News, News Stories & Editorials, We're In the News, , , , , , , , , ,

Brandon Lee and Alex Ruoff, Bloomberg Government: October 23, 2020

U.S. vaccine advisers questioned whether safety and efficacy standards set by Food and Drug Administration officials were high enough to warrant emergency authorization of a shot.

About two dozen outside advisers to the FDA with expertise in infectious diseases met yesterday to weigh in on agency standards that require a vaccine to work in at least 50% of people and for drugmakers to collect two months of safety data on at least half of clinical trial volunteers.

“They haven’t gone far enough” in terms of safety, said Hayley Altman-Gans, a panel member and pediatrics professor at Stanford University Medical Center.

Many panel members and outside researchers who commented during the hearing worried that if a vaccine is rushed out that later turns out to have safety problems or to be less effective than promised, it could backfire in a big way, undermining public confidence in Covid-19 vaccines for years to come.

Several panel members expressed concern that the two-month safety follow-up the FDA is calling for before a vaccine gets an emergency authorization is simply not enough. In addition to safety, it means that doctors won’t know whether a vaccine’s efficacy could fade after just a few months.

Diana Zuckerman of the National Center for Health Research told the committee the vaccine trials “have serious design flaws.”

The trials are too geared to preventing mild infections, and may not show whether they prevent severe infections and hospitalizations, she said. Longer follow up may be especially important because some of the first vaccines, including messenger RNA vaccines from Pfizer and Moderna, are based on new technologies that have never been used in an approved product.

FDA Panel To Lay Regulatory Groundwork For COVID-19 Vaccine

Noel King and Sydney Lupkin, NPR: October 22, 2020

NOEL KING, HOST:

There are several COVID-19 vaccines in development. But before they are approved, they have to be safe. It’s the FDA’s job to ensure that. Today an FDA advisory panel is meeting for the first time about the coronavirus vaccine. It’ll be making recommendations based not on politically motivated timetables, but on data.

Sydney Lupkin covers the pharmaceutical industry for NPR. Good morning, Sydney.

SYDNEY LUPKIN, BYLINE: Good morning.

KING: So what is the deal with this FDA panel? Who’s on it? What are they going to be doing?

LUPKIN: Well, the FDA regularly turns to committees of outside advisers for guidance. Most often, these panels are asked to evaluate specific drugs or health products, and that helps the agency to decide whether to approve these products. Today’s meeting of the committee that looks at vaccines is going to be a little different.

KING: How?

LUPKIN: Like everything else in this pandemic, it’s a bit unusual. The big difference is that the committee isn’t going to be sifting through data for a specific coronavirus vaccine like it normally would. The meeting will be a broader discussion of how the agency should think about safety and effectiveness of these new kinds of vaccines, particularly safety. Dr. Paul Offit is a committee member who works at the Children’s Hospital of Philadelphia.

PAUL OFFIT: How robust should safety data be? How long, for example, after the first or second dose should patients be followed or participants be followed for any possible safety issue?

LUPKIN: They’ll be discussing FDA’s existing guidance to companies, which includes some of that information. They’ll also discuss how studies should continue after the first vaccine is given the green light. What do you do for patients who got a placebo once a vaccine is widely available? Of course, the FDA usually heeds the advice of these committees, but it doesn’t have to.

KING: So since there’s no vaccine to review, I would think that in ordinary times, we would not know about this meeting. It would not be news at all. It’s very clear that the FDA wants to make public that this is happening. Why do they want to do that?

LUPKIN: Well, I mean, it gives the American public a window into the process. There’s been so much discussion around whether the FDA will put politics ahead of science. So it’s important to see what’s going on. And the FDA has questions that it wants answers to. Here’s Dr. Miles Braun, a former FDA epidemiologist.

MILES BRAUN: There is a level of humility that the FDA is coming to its advisers with. And I think that’s a good thing. And if they find out they’ve missed some important things, they’ll address those.

LUPKIN: Committee members will hear presentations from scientists at the FDA, the Centers for Disease Control and Prevention and the Biomedical Advanced Research and Development Authority. The public will also have an opportunity to weigh in. Diana Zuckerman is the president of the National Center for Health Research, an advocacy group slated to speak.

DIANA ZUCKERMAN: We’ve seen the guidance of what they’re telling companies they’re supposed to be studying. Frankly, they’re not very stringent, so we are concerned about them.

LUPKIN: She hopes the meeting will delve into making sure the clinical trials are diverse, for example. She also questions whether the study approach the FDA suggested to manufacturers is long enough to assess vaccine safety.

FDA Promises Strong Safety Standards for Covid-19 Vaccines as It Convenes Advisory Panel

In the News, News Stories & Editorials, We're In the News, , , , , , , , ,

Thomas M. Burton, Wall Street Journal: October 23, 2020

SILVER SPRING, Md.—Food and Drug Administration officials gave fresh assurances Thursday that Covid-19 vaccines will undergo rigorous testing before being made widely available—a message they underscored in a meeting with outside medical experts aimed at bolstering the agency’s credibility.

“Only those vaccines that are demonstrated to be safe and effective” will be licensed by the FDA, said Marion F. Gruber, director of the FDA’s Office of Vaccines Research and Review. But some speakers and panel members raised concerns about whether the FDA’s vaccine guidelines for Covid-19 clinical trials are sufficiently rigorous.

These comments came at the first meeting of a 25-member panel of medical experts, including specialists in fields like virology, infectious diseases and biostatistics. The group, which met remotely via video-conferencing, was  established to make recommendations to the FDA on how best to assess the safety and effectiveness of vaccines.

“The FDA frequently convenes outside panels of medical experts for their advice on products,” said Peter Marks, director of the FDA’s center for biological products. “But normally panels about vaccines are watched by dozens of people. In this case, it’s watched by many thousands.”

President Trump has pushed to get a vaccine approved quickly, which has drawn concern from some public health experts and political opponents that the FDA would be under pressure to bypass usual precautions to rush a vaccine to market quickly.

FDA officials have vowed not to do so. In addition to convening the advisory panel, they have issued a set of guidelines to govern how vaccine clinical trials will be conducted and evaluated.

They also formulated a set of rigorous standards for the FDA to employ before granting what is known as an emergency-use authorization (EUA) for a vaccine. The EUA is the faster equivalent during the Covid-19 pandemic of a conventional approval by the agency.

[….]

Various speakers questioned whether the shorter EUA test period was sufficient.

“The vaccine trials have serious design flaws,” said Diana Zuckerman, president of the National Center for Health Research in Washington. In addition to the two-month period, she said FDA guidelines focus on measuring milder cases of the disease, and not the most serious cases.
