Primary purpose: TREATMENT

Brief summary: The primary objectives of this study are to compare the efficacy of treatment with sofosbuvir/velpatasvir (SOF/VEL) fixed-dose combination (FDC) for 12 weeks with that of sofosbuvir (SOF) + ribavirin (RBV) for 24 weeks and to evaluate the safety and tolerability of each treatment regimen in participants with chronic genotype 3 hepatitis C virus (HCV) infection.


Eligibility criteria: Inclusion Criteria:

* Willing and able to provide written informed consent
* HCV RNA ≥ 10\^4 IU/mL
* HCV genotype 3
* Chronic HCV infection (≥ 6 months)
* Females of childbearing potential must have a negative serum pregnancy test
* Males and females of childbearing potential who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception

Exclusion Criteria:

* Current or prior history of clinically-significant illness (other than HCV) that may interfere with subject treatment, assessment or compliance with the protocol
* Screening ECG with clinically significant abnormalities
* Laboratory results outside of acceptable ranges at Screening
* Pregnant or nursing female or male with pregnant female partner
* Chronic liver disease of a non-HCV etiology (e.g., hemochromatosis, Wilson's disease, alfa-1 antitrypsin deficiency, cholangitis)
* Infection with hepatitis B virus (HBV) or human immunodeficiency virus (HIV)
