Title: A Phase 3, Multicenter, Randomized, Double-Blind, Placebo-Controlled Study to Investigate the Efficacy and Safety of GS-7977 + Ribavirin for 12 Weeks in Subjects With Chronic Genotype 2 or 3 HCV Infection Who Are Interferon Intolerant, Interferon Ineligible or Unwilling to Take Interferon
Brief Summary: This multicenter study was to evaluate subjects with chronic genotype 2 or 3 HCV infection who were interferon (IFN) ineligible, IFN intolerant or unwilling to take IFN. Participants were randomized in a 3:1 ratio to receive sofosbuvir (SOF)+ribavirin (RBV), or placebo to match SOF+placebo to match RBV. Randomization was stratified by presence/absence of cirrhosis. Approximately 20% of participants may have had evidence of cirrhosis at screening.


Options:
A: Inclusion Criteria:

* Participants with documented chronic hepatitis C infection as evidenced by presence of HCV antibody at least 6 months (180 days) prior to the informed consent. - Participants with genotype 1 HCV infection. - Participants with plasma HCV RNA level of ≥ 5.0 log10 IU/mL at screening.

Exclusion Criteria:

* Participants diagnosed with hepatic cirrhosis or hepatic failure. - Participants with any other liver disease than hepatitis C. - Participants with infection/co-infection with non-genotype 1 HCV.
B: Inclusion Criteria:

* Patient must have chronic hepatitis C infection (genotype 1) with HCV RNA level \>= 1000 IU/mL
* Patient must have failed at least 1 prior course of Peg-IFN/RBV therapy (standard treatment)
* Patient must be willing to use 2 effective methods of birth control for up to 7 months after last dose of study medication

Exclusion Criteria:

* Patient is a previous non-responder that is classified as a viral breakthrough case
* Patient is infected with Hepatitis C virus, genotype 1, exhibiting more than one subtype
* Patient has Hepatitis C virus, genotype 1, and exhibits co-infection with any other genotype
* Evidence of decompensated liver disease
* Patient has condition that requires use of systemic corticosteroids
C: Inclusion Criteria:

* Infection with HCV genotype 2 or 3
* Cirrhosis determination
* Subject meets one of the following classifications:

  1. IFN unwilling
  2. IFN ineligible
  3. IFN intolerant
* Screening laboratory values within defined thresholds
* Subject has not been treated with any investigational drug or device within 30 days of the Screening visit
* Use of highly effective contraception methods if female of childbearing potential or sexually active male

Exclusion Criteria:

* Prior exposure to an direct-acting antiviral targeting the HCV nonstructural protein (NS)5B polymerase
* Pregnant or nursing female or male with pregnant female partner
* Current or prior history of clinical hepatic decompensation
* History of clinically-significant illness or any other major medical disorder that may interfere with subject treatment, assessment or compliance with the protocol
* Excessive alcohol ingestion or significant drug abuse

Inclusion Criteria:

* Males and females, ≥ 18 years of age
* HCV Genotype 1b who previously failed treatment with peginterferon alfa and ribavirin, classified as previous null or partial responders based on previous therapy, OR intolerant or ineligible to P/R due to neutropenia, anemia, depression or thrombocytopenia with fibrosis/cirrhosis, OR treatment naive
* HCV RNA ≥ 10,000 IU/mL
* Seronegative for Human immunodeficiency virus (HIV) and Hepatitis B surface antigen (HBsAg)
* Subjects with compensated cirrhosis are permitted (compensated cirrhotics are capped at approximately 25% of treated population)

Exclusion Criteria:

* Prior treatment of HCV with HCV direct acting antiviral (DAA)
* Evidence of a medical condition contributing to chronic liver disease other than HCV
* Evidence of decompensated liver disease including, but not limited to, a history or presence of ascites, bleeding varices, or hepatic encephalopathy
* Diagnosed or suspected hepatocellular carcinoma or other malignancies
* Uncontrolled diabetes or hypertension
