A Study of RO5428029 in Healthy Volunteers and Patients With Chronic Hepatitis C

This study has been completed.
Information provided by (Responsible Party):
Hoffmann-La Roche Identifier:
First received: June 6, 2011
Last updated: November 1, 2016
Last verified: November 2016
This 2-part, randomized, double-blind, placebo-controlled study will assess the safety, pharmacokinetics and pharmacodynamics of RO5428029 in healthy volunteers and patients with hepatitis C infection. Cohorts will be randomized to receive either RO5428029 in ascending doses or placebo for up to 7 days (patients) or up to 14 days (healthy volunteers).

Condition Intervention Phase
Hepatitis C, Chronic, Healthy Volunteer Drug: RO5428029 Drug: placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Official Title: A Multi-Center, Randomized, Double-Blind, Multiple Ascending Dose, Placebo-Controlled, Parallel Group 2-Part Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamic of the HCV Nucleoside Inhibitor RO5428029 in Healthy Subjects and in CHC Genotype 1 Infected Patients
