The early-stage asset may potentially be used as a treatment of sundowning in Alzheimer's disease and Irregular Sleep Wake Rhythm Disorder in Parkinson's disease.
Sundowning is a symptom experienced by 20 percent or more of patients who become confused, anxious or agitated later in the day. ISWRD is a circadian rhythm disorder that leads to fragmented sleep and severe fatigue.

"This asset is highly complementary to our existing pipeline of potential disease-modifying therapies in Alzheimer's and Parkinson's diseases," Biogen Chief Medical Officer Alfred Sandrock Jr. said in a statement.
Last March, Biogen and its Japanese partner Eisai halted advanced trials of their experimental Alzheimer's treatment that was expected to bring in up to $12 billion a year in revenue. Rivals Eli Lilly, AstraZeneca and Merck have also recently abandoned experimental treatments for Alzheimer's.
Biogen expects the deal to close in the first quarter of 2020.
