If Robert Califf, the White House nominee for commissioner of the U.S. Food and Drug Administration, is confirmed by the Senate, he’ll take the reins of an agency with its reputation in tatters. Once revered as the global leader in drug regulation, the FDA has approved one bad drug and medical device after another over the past 30 years, leaving staff demoralized and overseas regulators scratching their heads. Meanwhile, about a third of Americans refuse to get vaccinated for COVID-19, in part because they distrust government and scientific institutions.
In the case of the FDA, at least some of that mistrust is deserved even if the COVID vaccines are generally safe. (We’ve both taken them.) The most recent FDA disaster erupted in June, when officials approved the Alzheimer’s drug Aduhelm over the objections of the agency’s biostatistician and an 11-member committee of expert advisers. The data submitted by Biogen, the drug’s manufacturer, failed to show that Aduhelm is effective. It also poses a significant risk of harm, including brain bleeds and swelling in about a third of test subjects. Agency higher-ups decided to overlook these shortcomings and put the drug on a fast track for approval.
The Aduhelm debacle and other FDA blunders can be traced to declining scientific standards at the agency and increasingly cozy ties with the companies it regulates.
All of which suggests there’s not much chance that Califf would be the reformer the FDA needs. With eternal hope that the full Senate will reject him or, if he’s confirmed, he and the White House will pursue a reform agenda, we talked to several experts about their priorities for fixing the agency. In their view and ours, the following represent the top five actions that need to be taken.
1. Enforce commitments made by drugmakers.
The FDA awards expedited or fast-track approvals for drugs with a promise by the manufacturer that it will conduct further, more rigorous studies. However, by 2018, according to a recent review, companies followed through on only 38 percent (166 of 437) of drugs.
2. Rescind the approval of drugs that cause harm but don’t benefit patients.
When follow-up studies show that drugs are ineffective or dangerous, the FDA needs to pull them. Right now, drugs are still being prescribed to patients even though rigorous clinical trials have shown they don’t work. The agency recently allowed four out of six widely used (and heavily advertised) cancer drugs to stay on the market after their follow-up studies failed to show any benefit. Only five of 54 costly, toxic cancer drugs approved by the agency between 2008 and 2012 improved survival rates.
3. Restore rigorous scientific standards.
Many experts, including multiple FDA insiders, have complained about the progressive decay of scientific standards at the agency. This has only gotten worse since 2016, with the passage of the 21st Century Cures Act, which gives the FDA enormous leeway in what kinds of studies it demands of companies in order to get their drugs approved. The FDA needs flexibility, says Steven Goodman, associate dean of clinical and translational research at Stanford, “but it has been erring on the side of lowering the scientific bar.”
For most drugs, companies should be required to produce two randomized clinical trials, the gold standard of medical science, showing that the drug provides meaningful benefit. Fewer drugs should be approved based on a “surrogate marker,” often an imaging study or blood test that is affected by a drug but may have little to do with whether or not patients benefit. “Too many FDA decisions have been based on wishful thinking rather than medical evidence,” says Diana Zuckerman, president of the National Center for Health Research, a Washington, D.C.–based public health think tank.
4. Clean house.
Somebody needs to jam the revolving door at the FDA. Physicians, scientists, and administrators come to the agency from industry, push industry-friendly decisions, and then leave government for new, lucrative positions in the private sector.
Take Patrizia Cavazzoni, the head of the FDA Center for Drug Evaluation and Research, who oversaw the approval of Aduhelm. Before joining the agency in 2019, Cavazzoni spent nearly two decades in high-level positions with the pharmaceutical giants Pfizer, Eli Lilly, and Sanofi-Aventis. After overruling the FDA advisory committee’s resounding vote against Aduhelm, she suggested that industry “partner” with the FDA in choosing committee members, an idea that violates the whole point of having outside, independent advisers.
5. Stop Big Pharma financing.
Finally, President Biden should call on Congress to fully fund the FDA by repealing the legislation mandating that the drug industry pay for its own reviews. “What really needs to happen is to mitigate the power that Pharma already has over the FDA,” says Erick Turner, professor of psychiatry at Oregon Health & Science University and a former member of an FDA advisory committee. That can’t happen as long as the FDA is dependent on industry money.
