Single and Multiple Ascending Dose Study of Aducanumab (BIIB037) in Japanese Participants With Alzheimer's Disease
- Registration Number
- NCT02434718
- Lead Sponsor
- Biogen
- Brief Summary
The primary objective of the study is to evaluate the safety and tolerability of single and multiple intravenous (IV) infusions of Aducanumab in Japanese participants with mild to moderate Alzheimer's Disease (AD). The secondary objectives of this study are as follows: To evaluate the serum pharmacokinetics (PK) of Aducanumab after single and multiple intravenous (IV) infusions of Aducanumab; To evaluate the effect of single and multiple IV infusions of Aducanumab on immunogenicity.
