Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Documented chronic HCV genotype (GT) 1, GT4, or GT6 infection with no evidence of non-typeable or mixed GT infection (positive for anti-HCV antibody, HCV RNA, or any of the listed GTs at least 6 months prior to screening must be confirmed by screening lab results)

    Arms of the Study

    Arm 1

    Arm Type

    Experimental

    Arm Label

    Grazoprevir+Elbasvir

    Arm Description

    Participants receive a fixed-dose combination (FDC) of grazoprevir 100 mg plus elbasvir 50 mg once daily for 12 weeks and are followed-up for 24 weeks.

    Outcomes

    Primary Outcome Measures

    Percentage of Participants Achieving Sustained Virologic Response 12 Weeks After the End of All Study Therapy (SVR12)
    Blood was drawn from each participant to assess Hepatitis C Virus ribonucleic acid (HCV RNA) plasma levels using the Roche COBAS™ Taqman™ HCV Test, v2.0 (High Pure System). The Roche COBAS Taqman HCV Test, v2.0 assay (High Pure System) had a lower limit of quantification of 15 IU/mL and a limit of detection of 9.3 IU/mL (in plasma). SVR12 was defined as undetectable (<9.3 IU/mL) HCV RNA at 12 weeks after the end of all study therapy.
    Percentage of Participants Experiencing Adverse Events (AEs) During the Treatment Period and First 14 Follow-up Days
    An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol -specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.
    Percentage of Participants Discontinuing Study Therapy Due to AEs During the Treatment Period
    An AE is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol -specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE.

    Secondary Outcome Measures

    Percentage of Participants Achieving Sustained Virologic Response 24 Weeks After the End of All Study Therapy (SVR24)
    Blood was drawn from each participant to assess HCV RNA plasma levels using the Roche COBAS™ Taqman™ HCV Test, v2.0 (High Pure System). The Roche COBAS Taqman HCV Test, v2.0 assay (High Pure System) had a lower limit of quantification of 15 IU/mL and a limit of detection of 9.3 IU/mL (in plasma). SVR24 was defined as undetectable (<9.3 IU/mL) HCV RNA at 24 weeks after the end of all study therapy.

    Brief Summary
    The purpose of this study is to assess the efficacy and safety of grazoprevir (MK-5172) 100 mg in combination with elbasvir (MK-8742) 50 mg in the treatment of chronic hepatitis C virus (HCV) in participants who are co-infected with human immunodeficiency virus (HIV). The primary hypothesis is that the percentage of participants who receive grazoprevir + elbasvir and achieve Sustained Virologic Response after 12 weeks of therapy (SVR12) will be greater than 70%.
