On Monday, the US Food and Drug Administration granted approval to a keenly-watched Alzheimer’s drug, aducanumab, developed by the drugmaker Biogen. The decision to approve the drug, which was once abandoned as a failure, has been the subject of debate within the scientific and regulatory community for months.

Aducanumab, which will be marketed as Aduhelm, is the first novel Alzheimer’s treatment to be approved since 2003, the FDA noted in a press release. Aducanumab is also the first novel treatment designed to address one of several proposed underlying causes of Alzheimer’s: the buildup of beta-amyloid plaques in the brain that disrupt the communication of neurons.
