Alzheimer’s drug panned by experts is OK’d by FDA
WASHINGTON — Government health officials on Monday approved the first new drug for Alzheimer’s disease in nearly 20 years, disregarding warnings from independent advisers that the much-debated treatment hasn’t been shown to help slow the brain-destroying disease.
The Food and Drug Administration said it approved the drug from Biogen based on results that seemed “reasonably likely” to benefit Alzheimer’s patients.
It’s the only therapy that US regulators have said can likely treat the underlying disease, rather than manage symptoms like anxiety and insomnia.
The decision, which could impact millions of Americans and their families, is certain to spark disagreements among physicians, medical researchers and patient groups. It also has far-reaching implications for the standards used to evaluate experimental therapies, including those that show only incremental benefits.
The new drug, which Biogen developed with Japan’s Eisai Co., did not reverse mental decline, only slowing it in one study. The medication, aducanumab, will be marketed as Aduhelm and is to be given as an infusion every four weeks.
Dr. Caleb Alexander, an FDA adviser who recommended against the drug’s approval, said he was “surprised and disappointed” by the decision.
“The FDA gets the respect that it does because it has regulatory standards that are based on firm evidence. In this case, I think they gave the product a pass,” said Alexander, a medical researcher at Johns Hopkins University.
The FDA’s top drug regulator acknowledged that “residual uncertainties” surround the drug, but said Aduhelm’s ability to reduce harmful clumps of plaque in the brain is expected to help slow dementia.
“The data supports patients and caregivers having the choice to use this drug,” Dr. Patrizia Cavazzoni told reporters. She said FDA carefully weighed the needs of people living with the “devastating, debilitating and deadly disease.”
Under terms of the socalled accelerated approval, the FDA is requiring the drugmaker to conduct a follow-up study to confirm benefits for patients. If the study fails to show effectiveness, the FDA could pull the drug from the market, though the agency rarely does so.
Biogen said the drug would cost approximately $56,000 for a typical year’s worth of treatment, and said the price would not be raised for four years. Most patients won’t pay anywhere near that amount thanks to insurance coverage and other discounts. The company said it aims to complete its follow-up trial of the drug by 2030.
The new medicine is manufactured from living cells and will be given via infusion at a doctor’s office or hospital.
