Available IPD datapackage for study 'A Randomized, Blinded, Placebo-Controlled, Serial-Cohort, Multiple Ascending Dose Study of the Safety, Tolerability, and Pharmacokinetics of BIIB033 in Subjects With Multiple Sclerosis'

The main purpose of the study is to evaluate the safety, tolerability, and pharmacokinetic profile of two intravenous infusions of BIIB033 administered two weeks apart in subjects with MS. Approximately 42 MS subjects are planned to be enrolled in the study in 7 separate groups (i.e., 6 subjects per group). Each subsequent group will be administered a higher dose of BIIB033. Before a higher dose group is allowed to start, a Drug Safety Review Committee will review all safety data from previous groups enrolled, as well as data from another study where BIIB033 is being administered to healthy volunteers (215HV101).
