A Study on Safety, Pharmacokinetics and Pharmacodynamics of RO5508887 in Healthy Volunteers

This study has been completed.

Hoffmann-La Roche Identifier:
First received: October 24, 2011
Last updated: November 1, 2016
Last verified: November 2016
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.

Condition Intervention Phase
Healthy Volunteer Drug: Placebo Drug: RO5508887 Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double (Participant, Investigator)
Official Title: A Single-Center, Randomized, Double-Blind, Single and Multiple Ascending-Dose, Placebo-Controlled Study to Investigate the Safety, Tolerability, Pharmacokinetics (Including the Effect of Food) and Pharmacodynamics of RO5508887 Following Oral Administration in Healthy Subjects.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Safety/tolerability: Incidence of adverse events [ Time Frame: up to approximately 8 weeks ]

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 ]
  • Pharmacodynamics: Urine levels of RO5508887 [ Time Frame: predose to 72 hours post-dose ]
  • 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 ]
  • 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 ]
