Trial Outcomes & Findings for Sofosbuvir and Ribavirin in Treatment-Naive and Treatment-Experienced Subjects With Chronic Genotype 2 or 3 HCV Infection (NCT NCT01682720)

NCT ID: NCT01682720

Last Updated: 2014-10-09

Results Overview

SVR12 was defined as HCV RNA \< the lower limit of quantitation (LLOQ, ie, \< 25 IU/mL) 12 weeks following the last dose of study drug. Data for this outcome measure was not collected for the Placebo 12 Weeks (GT2/3) group.

Participant Flow

Participants were enrolled at a total of 77 study sites in Europe. The first participant was screened on 19 September 2012. The last participant observation occurred on 08 January 2014.

* 475 participants were screened and 421 were randomized. * 419 participants were randomized and received at least 1 dose of study drug (Safety Analysis Set). * 334 participants with genotype 2 or 3 hepatitis C virus (HCV) infection were randomized and received at least 1 dose of sofosbuvir (Full Analysis Set).
