Good News:
The study aims to enroll about 400 participants who test positive for what research indicates is one of the most common genetic drivers of Parkinson’s: mutations in a gene called LRRK2. The drug Biogen and Denali are co-developing, now named BIIB122, is meant to stifle LRRK2, and is being tested against a placebo to see if it can significantly slow the worsening of symptoms in patients with early-stage Parkinson’s.
Bad News:
