Brief Summary:
The purpose of this study is to evaluate the efficacy of 6 or 8 weeks of treatment regimen containing simeprevir (SMV), daclatasvir (DCV) and sofosbuvir (SOF) in treatment-naive (not having received treatment with any approved or investigational drug) participants with chronic hepatitis (inflammation of the liver) C virus (HCV) genotype 1 infection with early stages of liver fibrosis or with cirrhosis.

Condition or disease Intervention/treatment Phase
Hepatitis C Virus Drug: Simeprevir 150 mg Drug: Daclatasvir 60 mg Drug: Sofosbuvir 400 mg Phase 2

Detailed Description:
This is an open-label (participants and researchers are aware about the treatment participants are receiving), and multicenter (when more than 1 hospital or medical school team work on a medical research) study. The study will consist of a Screening Phase (6 weeks); an Open-label Treatment Phase (6 weeks for Arm A and 8 weeks for Arm B); and a Post-treatment Follow-up Phase (until 24 weeks after end of study treatment). Using a staggered approach, all eligible participants will be assigned to 1 of the 2 arms, according to their level of fibrosis. Arm A (consists of chronic HCV genotype 1 infected participants with early stages of liver fibrosis): participants will receive a combination therapy of SMV 150 milligram (mg), DCV 60 mg and SOF 400 mg once daily for 6 weeks. Arm B (consists of chronic HCV genotype 1 infected participants with cirrhosis): participants will receive a combination therapy of SMV 150 mg, DCV 60 mg and SOF 400 mg once daily for 8 weeks. A sub-study will be performed at a selected study site, where only participants who will be eligible to participate in both the main study and the sub-study will be enrolled. Intra-hepatic and plasma HCV ribonucleic acid (RNA) levels; intra-hepatic, peripheral innate and adaptive immune responses during the treatment, will be assessed in the sub-study. Participants' safety will be monitored throughout the study.

Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response (SVR) at 12 Weeks After End of Study Drug Treatment (SVR12) [ Time Frame: 12 weeks after end of study drug treatment (week 18 for Arm A and week 20 for Arm B) ]
    Participants were considered to have achieved SVR12 if the hepatitis C virus ribonucleic acid (HCV RNA) was less than (<) lower limit of quantification (LLOQ; 15 international unit per milliliter [IU/mL]) detectable or undetectable at 12 weeks after the end of study drug treatment.


Secondary Outcome Measures :
  1. Percentage of Participants With On-treatment Virologic Response [ Time Frame: Day 2, Day 3, Week 1, 2, 3, 4, 6 (for Arm A) and 8 (for Arm B only) ]

    On-treatment virologic response was determined by hepatitis C virus (HCV) ribonucleic acid (RNA) results satisfying a specified threshold.

    The following thresholds were considered at any time point: <LLOQ undetectable, <LLOQ detectable, and <LLOQ undetectable or detectable. The LLOQ value was 15 IU/mL. Very rapid virologic response (vRVR) is undetectable HCV RNA at Week 2 while on treatment and Rapid virologic response (RVR) is undetectable HCV RNA at Week 4 while on treatment.


  2. Percentage of Participants With Sustained Virologic Response at 4 Weeks (SVR4) and 24 Weeks (SVR24) After End of Study Drug Treatment [ Time Frame: 4 weeks after end of study drug treatment (week 10 for Arm A and 12 for Arm B); 24 weeks after end of study drug treatment (week 30 for Arm A and 32 for Arm B) ]
    Participants were considered to have achieved SVR4 and SVR24 if the HCV RNA was <LLOQ detectable or undetectable at 4 weeks and 24 weeks respectively after the end of study drug treatment. The LLOQ value was 15 IU/mL.

  3. Percentage of Participants With On-Treatment Failure [ Time Frame: Baseline up to End of Treatment (Week 6 for Arm A and Week 8 for Arm B) ]
    Participants who did not achieve SVR12 and with confirmed detectable HCV RNA at the actual end of treatment. Includes participants with: 1) viral breakthrough, defined as a confirmed increase of greater than (>)1 log10 in HCV RNA from nadir, or confirmed HCV RNA 2) confirmed detectable HCV RNA at the actual end of treatment (example, completed treatment, discontinued due to adverse events, withdrawal of consent) of >100 IU/mL in participants whose HCV RNA had previously been <LLOQ while on treatment.

  4. Number of Participants With Viral Relapse [ Time Frame: From Week 6 to Week 18 (for Arm A) and From Week 8 to Week 20 (for Arm B) ]
    Viral Relapse: Participants who did not achieve SVR12, with undetectable HCV RNA at the actual end of study drug treatment and confirmed HCV RNA greater than or equal to (>=) LLOQ during followup.

  5. Number of Participants With Late Viral Relapse [ Time Frame: From Week 18 to Week 30 (for Arm A), From Week 20 to Week 32 (for Arm B) ]
    Late Viral Relapse: Participant who achieved SVR12 and the post treatment HCV RNA measurement fulfilled 1 the following conditions: a) at least 2 consecutive measurements not lesser than (<)15 IU/mL undetectable, of which at least the second measurement was >=15 IU/mL quantifiable or b) the last available measurement was >=15 IU/mL quantifiable.

  6. Number of Participants With HCV Nonstructural Protein 3/4A (NS3/4A), NS5A and NS5B Sequence in Participants Not Achieving SVR [ Time Frame: Up to Week 30 for Arm A and up to Week 32 for Arm B ]
    Sequencing of the HCV nonstructural protein 3/4A (NS3/4A), nonstructural protein 5A (NS5A) and nonstructural protein 5B (NS5B) genes was done to identify preexisting sequence polymorphisms and characterize emerging HCV viral variants in participants not achieving SVR.

  7. Percentage of Participants With or Without an NS3 Q80K Polymorphism at Baseline Achieving SVR [ Time Frame: up to Week 30 for Arm A and Week 32 for Arm B ]
    The Q80K polymorphism, associated with low level SMV in vitro resistance. Percentage of participants who achieved SVR with or without an NS3 Q80K polymorphism at baseline were reported.
