Multiple Dose Study of Aducanumab (BIIB037) (Recombinant, Fully Human Anti-Aβ IgG1 mAb) in Participants With Prodromal or Mild Alzheimer's Disease
The primary objective of this study is to evaluate the safety and tolerability of multiple doses of Aducanumab (recombinant, fully human anti-Aβ IgG1 mAb) in participants with prodromal or mild Alzheimer's Disease (AD). The secondary objectives of this study are to assess the effect on cerebral amyloid plaque content as measured by florbetapir-fluorine-18 (18F-AV-45F-AV-45) positron emission tomography (PET) imaging, to assess the multiple dose serum concentrations of Aducanumab and to evaluate the immunogenicity of Aducanumab after multiple dose administration in this population.
Study was discontinued based on futility analysis conducted on Phase 3 trials (NCT02477800 and NCT02484547) and not based on safety concerns. Follow-up visits and closing out study activities in progress.
Stanford is currently not accepting patients for this trial.
