(Reuters) - Biogen Inc (NASDAQ:BIIB) said on Monday its research chief Alfred Sandrock, who led development of its Alzheimer's disease drug Aduhelm, is leaving the company after a 23-year run.

The company said Sandrock will retire by the end of this year, and Priya Singhal will lead the research & development unit on an interim basis until a permanent successor is identified.

Sandrock has been the face of Biogen's controversial drug Aduhelm, which was approved by U.S. Food and Drug Administration in June for its ability to remove sticky deposits of another protein called amyloid beta - a likely contributor to Alzheimer's.
