A Study to Determine the Biodistribution, Safety, and Tolerability of a Microdose of Radiolabeled BIIB080 Co-administered With BIIB080 in Healthy Adults
Recruiting
In this study, researchers will learn more about a study drug called BIIB080. BIIB080 is currently a drug under investigation for treatment of Alzheimer's disease. The main question researchers are trying to answer in this study is how radiolabeled BIIB080 distributes in the brain and spinal cord. To help answer this question, researchers will use positron emission tomography (PET) scanner that can detect radiolabeled BIIB080 after a single injection of a small dose of radiolabeled BIIB080 (\[89...
