The US Food and Drug Administration (FDA) approved aducanumab on June 7, 2021, using an accelerated approval mechanism, based on evidence that aducanumab reduced brain β-amyloid (Aβ) peptide.1 The FDA press release stated that the effect on the surrogate end point "is reasonably likely to predict a clinical benefit to patients."at some point in the future.
