研究概览
简要总结
This was an efficacy and safety study of grazoprevir (MK-5172) in combination with elbasvir (MK-8742) in treatment-naive participants with chronic hepatitis C virus (HCV) genotype (GT) 1, 4, or 6 infection. Participants were randomly assigned (3:1 ratio) to immediate treatment or deferred treatment (placebo control). The primary efficacy hypothesis was that the proportion of participants receiving combination therapy in the Immediate Treatment Arm who achieve sustained viral response at 12 weeks after the end of study treatment (SVR12) is superior to 73%.

研究组 & 干预措施
Immediate Treatment Group
Participants received blinded grazoprevir 100 mg / elbasvir 50 mg fixed-dose combination (FDC) tablet orally once daily for 12 weeks followed by a 24-week follow-up period
干预措施: Grazoprevir 100mg / Elbasvir 50 mg FDC (Drug)
Deferred Treatment Group
Participants received blinded placebo tablet orally once daily for 12 weeks; after a 4-week unblinding/washout period participants received open label grazoprevir 100 mg / elbasvir 50 mg FDC tablet orally once daily for 12 weeks. Follow-up was continued for an additional 24 weeks.
干预措施: Grazoprevir 100mg / Elbasvir 50 mg FDC (Drug)
Deferred Treatment Group
Participants received blinded placebo tablet orally once daily for 12 weeks; after a 4-week unblinding/washout period participants received open label grazoprevir 100 mg / elbasvir 50 mg FDC tablet orally once daily for 12 weeks. Follow-up was continued for an additional 24 weeks.
干预措施: Placebo to Grazoprevir / Elbasvir 50 mg FDC (Drug)
结局指标
主要结局
Percentage of Participants Achieving Sustained Virologic Response at 12 Weeks After the End of Treatment (SVR12)
时间窗: Week 24 (12 weeks after the end of treatment)
Hepatitis C Virus (HCV) ribonucleic acid (RNA) was measured using the Roche COBAS® Taqman® HCV Test, v2.0 assay. SVR12 was defined as HCV RNA \<Lower Limit of Quantification (\<15 IU/mL) 12 weeks after the end of all study therapy.
Percentage of Participants Discontinued From Study Treatment Because of an Adverse Event
时间窗: Up to Week 12 (end of Blinded Treatment)
An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), 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 of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event.
Percentage of Participants Experiencing at Least One Adverse Event
时间窗: Up to Week 14 (14 days after the Blinded Treatment was completed)
An adverse event is defined as any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), 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 of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event.
次要结局
