  Purpose

This randomized, double-blind, placebo-controlled, cross-over study will assess the safety, pharmacokinetics and pharmacodynamics of RO5508887 in healthy volunteers. In Part 1, subjects will be randomized to receive single ascending doses of either RO5508887 or placebo. In Part 2, subjects will receive a single dose of RO5508887 on two occasions, with or without food. Anticipated time on study is up to 12 weeks.

Primary Outcome Measures:
  • Safety/tolerability: Incidence of adverse events [ Time Frame: up to approximately 8 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Pharmacokinetics: Plasma concentrations of RO5508887 [ Time Frame: predose, 1.5, 3, 4, 4.5, 5, 5.5, 6, 7, 8, 12, 24, 48, 72, 96, 144 hours post-dose ] [ Designated as safety issue: No ]
  • Pharmacodynamics: Urine levels of RO5508887 [ Time Frame: predose to 72 hours post-dose ] [ Designated as safety issue: No ]
  • Pharmacodynamics: Plasma levels of markers of amyloid deposition (Abeta1-40/Abeta1-42) [ Time Frame: predose, 1.5, 3, 4, 4.5, 5, 5.5, 6, 7, 8, 12, 24, 48, 72, 96, 144 hours post-dose ] [ Designated as safety issue: No ]
  • Effect of food on pharmacokinetics (plasma concentrations) of a single dose of RO5508887 [ Time Frame: predose, 1.5, 3, 4, 4.5, 5, 5.5, 6, 7, 8, 12, 24, 36, 48, 60, 72 hours post-dose ] [ Designated as safety issue: No ]
