A Single Ascending And Multiple Ascending Dose Study of RO5271983 in Healthy Volunteers

This study has been completed.

Hoffmann-La Roche Identifier:
First received: September 24, 2010
Last updated: November 1, 2016
Last verified: November 2016
This placebo-controlled, randomized, observer-blind, dose-ascending study will investigate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple doses of RO5271983 in healthy volunteers. Healthy volunteers will be randomized to receive either a single oral dose of RO5271983 or placebo in the SAD part or multiple oral doses of RO5271983 or placebo in the MAD part. The anticipated time on study treatment is approximately 14 weeks for the SAD part and up to 8 weeks for the MAD part.

Condition Intervention Phase
Healthy Volunteer Drug: Placebo - MAD Drug: Placebo - SAD Drug: RO5271983 - MAD Drug: RO5271983 - SAD Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: A Phase 1 Placebo-controlled, Randomized, Observer-blind Combined Single and Multiple Ascending Dose Study to Investigate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of RO5271983 in Healthy Subjects.

Further study details as provided by Hoffmann-La Roche:

Primary Outcome Measures:
  • Single ascending dose (SAD): Pharmacokinetics (plasma concentration) of RO5271983 [ Time Frame: up to 240 hours ]
  • Single ascending dose (SAD): Safety (incidence of adverse events) [ Time Frame: 14 weeks ]
  • Single ascending dose (SAD): Tolerability (e.g. vital signs) [ Time Frame: 14 weeks ]
  • Multiple ascending doses (MAD): Pharmacokinetics (plasma concentration) of RO5271983 [ Time Frame: 17 days ]
  • Multiple ascending doses (MAD): Safety (incidence of adverse events) [ Time Frame: 8 weeks ]
  • Multiple ascending doses (MAD): Tolerability (e.g. vital signs) [ Time Frame: 8 weeks ]

Secondary Outcome Measures:
  • Effect of food on pharmacokinetics of RO5271983 [ Time Frame: up to 240 hours ]
  • Single ascending dose (SAD): Pharmacodynamics (blood analysis) of RO5271983 [ Time Frame: 72 hours ]
  • Multiple ascending doses (MAD): Pharmacodynamics (blood analysis) of RO5271983 [ Time Frame: 14 days ]
