Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group 1
Aducanumab, intravenous infusion, every 4 weeks for up to Week 52 during the randomized treatment period. The dose will be titrated to a desirable dose. Participants will be managed for drug continuation and suspension. Following a 4-week follow-up period, eligible participants will continue to receive aducanumab, intravenous infusion, every 4 weeks for an additional 104 weeks in the long-term extension period.
Aducanumab
Administered as specified in the treatment arm.
Placebo
Administered as specified in the treatment arm.
Group 2
Aducanumab, intravenous infusion, every 4 weeks for up to Week 52 during the randomized treatment period. The dose will be titrated to a desirable dose. Participants will be managed for drug continuation and suspension. Following a 4-week follow-up period, eligible participants will continue to receive aducanumab, intravenous infusion, every 4 weeks for an additional 104 weeks in the long-term extension period.
