Descrição
Inclusion Criteria:
- Participant must be infected with Hepatitis C virus (HCV) Genotype 1 (1a or 1b) with Baseline HCV ribonucleic acid (RNA) greater than (>) 10,000 international unit per milliliter (IU/mL). Retesting of HCV RNA to assess eligibility will be allowed once, using an unscheduled visit during the Screening period
- Participant must have had an orthotopic liver transplant greater than or equal to (>=) 6 months to 15 years prior to enrollment
- Participant must have had primary liver transplant
- Participant must be on a stable immunosuppressive regimen for at least 3 months prior to the Screening visit. Immunosuppression regimens may include calcineurin inhibitors (for example, tacrolimus), mammalian target of rapamycin (mTOR) inhibitor, mycophenolate mofetil, prednisone, prednisolone less than or equal to (<=) 5 milligram per day (mg/day), other corticosteroids (except systemic dexamethasone), sirolimus, everolimus, or azathioprine. Stable immunosuppression includes normal adjustment of immunosuppressant dose but excludes changes in immunosuppressant medication and/or treatment of rejection.
- Participant's renal function as measured by the Cockcroft Gault formula must be >30 milliliter per minute (mL/min)
Exclusion Criteria:
- Participants received prior treatment with an investigational or Food and Drug Administration (FDA) approved direct-acting antiviral drug for the treatment of hepatitis C. Prior HCV treatment with interferon or peginterferon with or without ribavirin (RBV) is allowed but must have been completed at least 3 months prior to Screening
- Participants with hepatic decompensation defined by any of the following: 1) Any post-liver transplant clinical signs including ascites, hepatic encephalopathy, and/or evidence of varices with or without variceal bleeding, and 2) Child-Turcotte-Pugh (CTP) score >=7
- Participant has (post-transplant) any underlying serious or life-threatening condition, such as severe uncontrolled cardiopulmonary disease, vascular disease, rheumatologic condition, renal failure, dialysis, ongoing systemic infection, uncontrolled malignancy, or other serious illness that would compromise adherence to medications and ability to comply with all aspects of the study protocol
- Any other active, clinically significant disease or clinically significant findings during the Screening period of medical history, physical examination, laboratory testing, or electrocardiogram (ECG) recording that, in the investigator's opinion, would compromise the participant's safety or could interfere with the participant participating in and completing the study. Retesting of laboratory results that lead to exclusion will be allowed once using an unscheduled visit during the Screening period to assess eligibility
- Participant is a woman who is pregnant, breast-feeding, or planning to become pregnant while enrolled in this study or within 6 months after the last dose of ribavirin (or longer when dictated by local regulations)

Percentage of Participants With Sustained Virologic Response After 12 Weeks of end of Treatment (SVR12)
Prazo: Week 24 or Week 36
|
Participants will be considered to have achieved SVR12 if the hepatitis C virus ribonucleic acid (HCV RNA) is less than (<) 15 international unit per milliliter (IU/mL) (detectable or undetectable) at 12 weeks after the end of treatment.
End of treatment is at Week 12 (for Arms 1 and 2) or Week 24 (for Arm 3); therefore, outcome will be measured at Week 24 (for Arms 1 and 2) or Week 36 (for Arm 3).

Percentage of Participants With Sustained Virologic Response After 4 Weeks of end of Treatment (SVR4)
Prazo: Week 16 (for Arms 1 and 2) and Week 28 (for Arm 3)
|
Participants will be considered to have achieved SVR4 if the hepatitis C virus ribonucleic acid (HCV RNA) is <15 IU/mL (detectable or undetectable) at 4 weeks after the end of treatment.

|
Plasma HCV RNA will be determined using an in vitro nucleic acid amplification test for the quantification of HCV RNA in human plasma using a sensitive assay (COBAS® AmpliPrep/COBAS® TaqMan® HCV Test v2.0 , lower limit of quantification = limit of detection = 15 IU/mL).

Change From Baseline in Hepatitis C Symptom and Impact Questionnaire Version 4 (HCV-SIQv4) Score at Week 24 (for Arms 1 and 2) and Week 36 (for Arm 3)
Prazo: Baseline, Week 24 (for Arms 1 and 2) and Week 36 (for Arm 3)
|
The HCV-SIQv4 is a self-administered questionnaire containing 33 items classified as 3 categories of scores: 1) Symptom severity score (sum of responses to 29 questions to assess severity or frequency of symptoms associated with HCV or its treatment; 2) Time missed from work/school (sum of responses to 3 questions regarding the impact of symptoms on work/school attendance); 3) Daily activity score (response to 1 question regarding the impact of symptoms on daily activities).
Higher HCV SIQv4 scores indicate worse symptom severity, more time missed from work/school, and more impairment in daily activities, respectively.
The total score is the sum of scores of these 3 categories.

Change From Baseline in EuroQol 5 - Dimension (EQ-5D) Questionnaire Score at Weeks 4, 8, 12, 16, 20, 24 (for all treatment arms) and Week 36 (for Arm 3)
Prazo: Baseline, Weeks 4, 8, 12, 16, 20, 24 (for all treatment arms) and Week 36 (for Arm 3)
|
The EQ-5D questionnaire is a brief, generic health-related quality of life assessment (HRQOL) that can also be used to incorporate participant preferences into health economic evaluations.
The EQ-5D questionnaire assesses HRQOL in terms of degree of limitation on 5 health dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) and as overall health using a "thermometer" visual analog scale with response options ranging from 0 (worst imaginable health) to 100 (best imaginable health).
Lower scores indicate worsening.
EQ-5D scores include EQ-5D valuation index score (a weighted scoring of the 5 dimension scores with a possible range from 0 to 1), EQ-5D visual analog scale (VAS) is a 20 centimeter (cm) vertical VAS with scores ranging from 0 (worst imaginable health) to 100 (perfect health), and EQ5D descriptive system scores (five scores reflecting each of the 5 EQ-5D health dimensions ranging from 0 [no limitation] to 4 [incapacity]).
