Title: A Phase 3, Multicenter, Randomized, Active-Controlled Study to Investigate the Safety and Efficacy of PSI-7977 and Ribavirin for 12 Weeks Compared to Pegylated Interferon and Ribavirin for 24 Weeks in Treatment-Naïve Patients With Chronic Genotype 2 or 3 HCV Infection
Brief Summary: This study was to assess the safety and efficacy of sofosbuvir (GS-7977; PSI-7977) in combination with ribavirin (RBV) administered for 12 weeks compared with pegylated interferon (PEG)/RBV administered for 24 weeks in treatment-naive patients with Hepatitis C (HCV) genotype 2 or 3. Efficacy was assessed by the rate of sustained viral response (SVR) 12 weeks after the discontinuation of therapy (SVR12). This was a non-inferiority study, and if non-inferiority was demonstrated, the study was then allowed to test for superiority.


Options:
A: 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
B: Inclusion Criteria:

* Has not received any previous treatment with any approved or investigational drug or drug regimen for the treatment of hepatitis C
* Male and female subjects, 18 to 70 years of age, inclusive
* Genotype 1, chronic hepatitis C with detectable HCV RNA.
* Screening laboratory values, tests, and physical exam within acceptable ranges
* Able and willing to follow contraception requirements
* Able to read and understand, and willing to sign the informed consent form and abide by the study restrictions.

Exclusion Criteria:

* Subject has any contraindications to Pegasys® or Copegus® therapy
* Evidence of hepatic decompensation in cirrhotic subjects
* History of organ transplant
* History of, or any current medical condition which could impact the safety of the subject in participation in the study
C: Inclusion Criteria:

* Infection with HCV genotype 1, 4, 5, or 6
* Cirrhosis determination
* Subject met the following classifications:

  * Treatment-naive
  * Screening laboratory values within defined thresholds
  * Not treated with any investigational drug or device within 30 days of screening
* 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 have interfered with subject treatment, assessment, or compliance with the protocol
* Excessive alcohol ingestion or significant drug abuse
D: Inclusion Criteria:

* Chronic Genotype 2 or 3 HCV-infection
* Naive to all HCV antiviral treatment(s)

Exclusion Criteria:

* Positive test at Screening for HBsAg, anti-hepatitis B core immunoglobulin M antibody (anti-HBc IgM Ab), or anti-HIV Ab
* History of any other clinically significant chronic liver disease
* A history consistent with decompensated liver disease
* History or current evidence of psychiatric illness, immunologic disorder, hemoglobinopathy, pulmonary or cardiac disease, seizure disorder or anticonvulsant use, poorly controlled diabetes, cancer, or a history of malignancy, that makes the subject unsuitable for the study.
* Participation in a clinical study within 3 months prior to first dose
