Title: A Multi-center, Placebo-Controlled, Dose Ranging Study to Investigate the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics Following Oral Administration of PSI-7977 in Combination With Pegylated Interferon and Ribavirin in Treatment-Naïve Patients With Chronic HCV Infection Genotype 1, and an Open Label Assessment of PSI-7977 in Patients With HCV Genotypes 2 or 3
Brief Summary: Genotype 1: Participants with genotype 1 hepatitis C (HCV) infection were randomized to receive sofosbuvir (GS-7977; PSI-7977) 200 mg or 400 mg, or matching placebo, plus pegylated interferon alfa 2a (PEG) and ribavirin (RBV) for 12 weeks, followed by PEG+RBV for an up to an additional 36 weeks. Randomization was stratified by IL28B status (CC, CT, TT) and HCV RNA level (\< 800,000 IU/ml or ≥ 800,000 IU/ml) at baseline. Participants were randomized in a 2:2:1 manner; those who achieved an extended rapid virologic response (eRVR) (HCV RNA \< lower limit of detection \[15 IU/mL\] from Weeks 4 through 12) received an additional 12 weeks of PEG+RBV. Subjects not achieving eRVR received an additional 36 weeks of PEG+RBV.

Genotype 2 and 3: Participants with genotype 2 or 3 hepatitis C (HCV) received sofosbuvir 400 mg plus PEG+RBV for 12 weeks.


Options:
A: Percentage of Participants Achieving RVR (Week 4); Number of Participants Experiencing an Adverse Event (AE) (Up to Day 42); Number of Participants Discontinuing From Study Therapy Due to AEs (Day 1 to Day 28)
B: Percentage of Participants Who Experienced Adverse Events During the Sofosbuvir Treatment Period (Baseline to Week 12 plus 30 days)
C: Change in Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Levels From Baseline to Week 4 (Day 1 (Baseline) and Week 4); The Percentage of Participants With Undetectable Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Levels During the Study (Weeks 4, 12, 24 or 48, and EOT (up to Week 24 or 48)); The Percentage of Participants With a Decrease of Greater Than or Equal to 2 log10 IU/mL From Baseline in Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Through the Post-treatment Follow-up Period (Days 1 (4 hr), 1 (8 hr), 3, Weeks 1, 2, 3, 4, 6, 8, 12, 16, 20, 24,28, 36, 42, 48, 52, 60, 72, and EOT (up to Week 24 or 48)); The Percentage of Participants With Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Levels Undetectable or Below the Limit of Quantification (<1.2 log10 IU/mL Detectable) During Treatment and During Post Treatment Follow-up (Week 4, 12, 24, 36, 48, EOT (up to Week 24 or 48), and Week 60 and 72); The Number of Participants With Viral Breakthrough (Up to EOT (up to Week 24 or 48)); The Percentage of Participants With Viral Relapse (Week 36 or 60); Actual Plasma Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Values up to Week 24 in the Post-treatment Follow-up Period (Baseline, Week 4, 12, 24, 48, EOT (up to Week 24 or 48), and Weeks 60 and 72); The Number of Participants With Alanine Aminotransaminase (ALT) Values Within the Normal Range at the End-of-treatment (EOT) (Day 1, Weeks 24, 48, and EOT (up to Weeks 24 or 48)); The Percentage of Participants With Sustained Virologic Response (SVR) (SVR4 (up to Week 28 or Week 52), SVR12 (up to Weeks 36 or 60), and SVR24 (up to Weeks 48 or 72)); Predose Plasma Concentrations (C0h) of TMC435 (Sparse Blood Sampling) (Weeks 4, 12, and 24); Predose Plasma Concentrations (C0h) of TMC435 (Intensive Blood Sampling) (Weeks 4 to 6); The Area Under the Plasma Concentration-time Curve From the Time of Administration up to 24 Hours After Dosing (AUC24) for TMC435 (within 15 minutes and at 1, 2, 4, 6, 8, 12, and 24 hours post-dose between Week 4 and Week 6 after the initiation of treatment); Time to Reach the Maximum Plasma Concentration (Tmax) of TMC435 (within 15 minutes and at 1, 2, 4, 6, 8, 12, and 24 hours post-dose between Week 4 and Week 6 after the initiation of treatment); The Number of Participants Who Met Virologic Stopping/Continuation Rules and Completed All Study Medications (Week 24)
D: Percentage of Participants With Sustained Virologic Response (SVR) at 12 Weeks After Discontinuation of Therapy (SVR12), Treatment-naive, Noncirrhotic Participants (Posttreatment Week 12); Percentage of Participants With Sustained Virologic Response at 12 Weeks After Discontinuation of Therapy (SVR12) (Posttreatment Week 12); Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event (Up to 12 weeks)
