Brief summary

This study will assess the safety and efficacy of alisporivir (ALV; DEB025) triple therapy \[i.e., when added to peginterferon alfa-2a (PEG) and ribavirin (RBV)\] to optimize treatment in treatment-naïve participants with hepatitis C virus (HCV) genotype 1 (GT1)

Interventions

DRUGPeginterferon alfa-2a

PEG 180 μg administered via subcutaneous (s.c.) injection once weekly

ALV 200 mg soft gel capsules administered orally

DRUGRibavirin

RBV 200 mg tablets (weight-based dose: \< 75 mg = 1000 mg/day; ≥ 75 kg = 1200 mg/day) administered orally in a divided daily dose

Participant flow

Recruitment details

Of the 1580 patients screened at multiple global sites, 1081 (68.4%) were randomized and 499 (31.6%) discontinued from the study prior to randomization.

Pre-assignment details

Due to mis-randomization, four patients did not have a baseline visit and never started study medications. They were included in screened and randomized, but excluded from the Full Analysis Set and the Safety Set.
