Participant Flow
Recruitment Details | This study consists of Placebo-Controlled Treatment Period (Weeks 0 to 78) and Delayed-Start Period (Weeks 78 to 156). |
Pre-assignment Details | In Period 1, per the protocol, placebo-controlled groups (Placebo for 78 weeks then Lanabecestat 20 mg; Placebo for 78 weeks then Lanabecestat 50 mg) were combined to form one placebo group. As study terminated early and very few participants entered into the period 2, the arms in period 2 are combined based on dose exposure for ease of comparison. |
