Biogen Slashes Price of Alzheimer’s Drug Aduhelm, as It Faces Obstacles


A group of Alzheimer’s experts and health advocates called on the Food and Drug Administration to pull Aduhelm off the market and said they were supporting an effort to file a formal petition with the agency to withdraw it.

“The F.D.A.’s decision to approve Aduhelm is indefensible in both scientific and clinical terms,” said a statement signed by 18 scientists, most of them doctors. “This drug should be withdrawn from the market immediately.”

The doctors and scientists who signed the statement also agreed to provide their expertise to support the filing of a citizen petition, a formal process to seek reversal of the F.D.A.’s decision. The petition will be filed by the Right Care Alliance, a coalition of clinicians, patients and community members, which is also circulating a pledge for physicians who promise not to prescribe Aduhelm and for patients and family members who say they will not request it. Dr. Vikas Saini, chairman of the Right Care Alliance and president of the Lown Institute, a health care think tank, said that while the citizen petition process can take months or years, it can prompt F.D.A. action.
