Disclosures

Dr. Petersen has consulted with Biogen on aducanumab, but he was not involved in the design or execution of the clinical trials.

Dr. Knopman is a former member of the FDA's Peripheral and Central Nervous System Advisory Committee, but he was recused for the aducanumab advisory hearing because he was a site principal investigator for one of Biogen's aducanumab trials.

Mayo Clinic campuses in Rochester, Minnesota, and Jacksonville, Florida, participated in aducanumab clinical trials.
