Inclusion Criteria:

• Male or female (of non-childbearing potential or using allowed contraceptive methods) at least 18 years of age time of Screening
• Participant had a positive anti-hepatitis C virus (HCV) antibody (Ab) and plasma HCV ribonucleic acid (RNA) greater than or equal to 1000 IU/mL at the Screening Visit.
• Participant had an estimated glomerular filtration rate (eGFR) less than 45 mL/min/1.73 m^2 as estimated by the Modification of Diet in Renal Disease (MDRD) method at Screening according to the following formula: eGFR (mL/min/1.73 m^2 ) = 175 × (Serum Creatinine) ^-1.154 × Age^-0.203 × (0.742 if female) × (1.212 if black), or were dialysis dependent. Subjects requiring dialysis had to have been receiving dialysis for at least 1 month prior to enrollment, and may have been on hemodialysis or peritoneal dialysis.
• Cirrhotic participants only: absence of hepatocellular carcinoma (HCC) as indicated by a negative ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI) within 3 months prior to Screening or a negative ultrasound at Screening. Participants who had an ultrasound with results suspicious of HCC followed by a subsequent negative CT or MRI of the liver were eligible for the study.

Exclusion Criteria:

• Female participants who were pregnant, breastfeeding, or were considering becoming pregnant during the study or for approximately 30 days after the last dose of study drug
• Current hepatitis B virus (HBV) or human immunodeficiency virus (HIV) infection on screening tests, defined as:
• Positive test result at Screening for hepatitis B surface antigen (HBsAg), or;
• HBV deoxyribonucleic acid (DNA) greater than lower limit of quantification (LLOQ) in participants with isolated positive hepatitis B core antibody (HBcAb), (i.e., negative HBsAg and Anti-HBsAg), or;
• Positive anti-HIV antibody (Ab).
• Any current or historical clinical evidence of decompensated cirrhosis, including any current or past evidence of Child-Pugh B or C classification, hepatic encephalopathy or variceal bleeding; radiographic evidence of small ascites; or prior or current empiric use of lactulose/rifaximin for neurologic indications. Prophylactic use of beta blockers was not exclusionary.
• Clinical history of acute renal failure in the 3 months prior to Screening
• History of severe, life-threatening, or other significant sensitivity to any excipients of the study drugs
• Clinically significant abnormalities or co-morbidities, or recent (within 6 months prior to study drug administration) alcohol or drug abuse that could preclude adherence to the protocol in the opinion of the investigator
• Receipt of any investigational or commercially available direct acting anti-HCV agents other than sofosbuvir
