Third member of FDA advisory panel resigns over Alzheimer's drug approval

A third member of a panel of outside advisers to the U.S. Food and Drug Administration has resigned in protest over the agency's decision to approve Biogen Inc's Alzheimer's disease treatment despite the committee's recommendation against doing so.

Aaron Kesselheim, a Professor of Medicine at Harvard Medical School who had served on the FDA’s advisory committee for nervous system drugs since 2015, told Reuters on Thursday he was stepping down from the panel.
