A Multiple Ascending Dose Study of R1450 in Patients With Alzheimer Disease.
A Multi-center, Multiple-ascending Dose, Randomized, Double-blind, Placebo-controlled, Parallel-group Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of RO4909832 Following Intravenous Infusion in AD Patients
This study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of R1450 in patients with mild to moderate Alzheimer Disease. Patients will be randomized to receive either R1450 or placebo by intravenous infusion for a total of 7 doses. The starting dose will be escalated in subsequent cohorts of patients in an adaptive manner, after a satisfactory assessment of safety, tolerability and pharmacokinetics of the previous dose. The anticipated time on study treatment is 3-12 months, and the target sample size is <100 individuals.
