Biogen and Eisai said the FDA had accepted and given priority review to their application for aducanumab. The drug will undergo an advisory committee meeting at an undisclosed date. Biogen’s stock rose 10%, but analysts had mixed opinions.
The FDA has 60 days to decide whether or not to accept the application. An analyst wrote that the agency accepting it with a priority or standard review may signal whether the agency is seriously considering approval or has continued reservations about the amyloid beta-targeting drug’s clinical benefit.
