The primary objective of the study is to evaluate the safety and tolerability of single and multiple intravenous (IV) infusions of BIIB037 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 BIIB037 after single and multiple intravenous (IV) infusions of BIIB037; To evaluate the effect of single and multiple IV infusions of BIIB037 on immunogenicity.

Primary Outcome Measures:
  • Incidence and nature of adverse events (AE) / serious adverse events(SAE) [ Time Frame: Up to week 42 ] [ Designated as safety issue: Yes ]
  • Clinically significant changes in vital signs and 12-lead electrocardiogram (ECG) data; abnormalities in neurological and physical examinations [ Time Frame: Up to week 42 ] [ Designated as safety issue: Yes ]
  • Brain magnetic resonance imaging (MRI) findings to assess amyloid-related imaging abnormalities (ARIA), including incidence of ARIA-E (edema) or ARIA-H (hemosiderosis) [ Time Frame: Up to week 42 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Area under the concentration-time curve (AUC) from time zero extrapolated to infinity (AUC0-∞) [ Time Frame: Up to 8 weeks post dosing ] [ Designated as safety issue: No ]
  • AUC from time zero to time of the last measurable concentration (AUC0-last) [ Time Frame: Up to 8 weeks post dosing ] [ Designated as safety issue: No ]
  • Maximum observed concentration (Cmax) [ Time Frame: Up to 8 weeks post dosing ] [ Designated as safety issue: No ]
  • Time to Cmax (Tmax) [ Time Frame: Up to 8 weeks post dosing ] [ Designated as safety issue: No ]
  • Elimination half-life (t1/2) [ Time Frame: Up to 8 weeks post dosing ] [ Designated as safety issue: No ]
  • Volume of distribution at steady state (Vss) [ Time Frame: Up to 8 weeks post dosing ] [ Designated as safety issue: No ]
  • Clearance (CL) after a single IV infusion of aducanumab (BIIB037) [ Time Frame: Up to 8 weeks post dosing ] [ Designated as safety issue: No ]
  • Incidence of anti-aducanumab (BIIB037) antibodies in serum [ Time Frame: Up to week 42 ] [ Designated as safety issue: Yes ]
