Hoffmann-La Roche Identifier:
First received: April 19, 2012
Last updated: November 1, 2016
Last verified: November 2016

This randomized, double-blind, placebo-controlled, parallel group study will evaluate the pharmacodynamics and pharmacokinetics of RO5508887 in healthy volunteers.

Subjects will be randomized in cohorts to receive single oral doses of either RO5508887 or placebo. In-unit period is 6 days.

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

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Official Title: A Single-Center, Randomized, Investigator/Subject-Blind, Single Dose, Placebo-Controlled, Parallel Group Study to Investigate the Pharmacodynamic and Pharmacokinetic Behavior of RO5508887 in Plasma and Cerebral Spinal Fluid Following Oral Administration in Healthy Volunteers

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Plasma levels of amyloid biomarkers [ Time Frame: Pre-dose and up to fullow up, 8-12 days post dose ]
  • Cerebral spinal fluid levels of amyloid biomarkers [ Time Frame: Pre-dose and up to 30 hours post-dose ]

Secondary Outcome Measures:
  • Safety: Incidence of adverse events [ Time Frame: approximately 6 months ]
  • Pharmacokinetics: Plasma and cerebral spinal fluid concentrations of RO5508887 (and metabolites) [ Time Frame: Pre-dose and up to 72 hours post-dose ]

Inclusion Criteria:

  • Healthy male subjects, 18 to 65 years of age, inclusive. Healthy status is defined by absence of evidence of any active or chronic disease following a detailed medical and surgical history and a complete physical examination
  • Body mass index (BMI) 18 to 30 kg/m2 inclusive
  • Must agree to use a barrier method of contraception during the treatment period and for at least 30 days after the last dose of study drug
  • Donation of blood over 500 mL within 6 weeks before drug administration

Exclusion Criteria:

  • Concomitant disease or condition or treatment that could interfere with the conduct of the study or would, in the opinion of the investigator, pose an unacceptable risk to the subject in this study

In addition, subject cannot participate unless completely recovered from previous invasive or study procedure
  • Donation of blood over 500 mL within 6 weeks before drug administration
