Brief summary

The purpose of this study is to provide anti-hepatitis C virus drugs to patients who received placebo + peginterferon alfa-2a + ribavirin in prior Bristol-Myers Squibb (BMS) studies and determine whether addition of these drugs results in higher cure rates in patients who previously failed therapy. Approximately 100 genotype 1b patients who received placebo in BMS study NCT01428063 (AI447-028) will receive active drugs in this study.

Detailed description

* Intervention Model: * Parallel: for all patients entering the trial * Cross-over: for genotype 1b patients rolling over from NCT01428063 (AI447-028) who require rescue therapy after initial treatment in this study * Peginterferon alfa-2a * Ribavirin * Daclatasvir * Asunaprevir

Recruitment details

The study was conducted at 92 centers in 20 countries.

Pre-assignment details

A total of 276 participants were enrolled, 228 were randomized and 227 received treatment. Participants were not treated because they no longer met study criteria (n=41), withdrew their consent (n=4), showed poor/non-compliance (n=1) or were lost to follow-up (n=2). One participant was randomized by mistake but received no treatment.
