A Phase IIb Clinical Study to Assess the Pharmacokinetics, Safety, and Efficacy of the Combination Regimen of Elbasvir (EBR)/Grazoprevir (GZR) in Participants Aged 3 to Less Than 18 Years With Chronic Hepatitis C Infection

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The purpose of this study is to assess the pharmacokinetics (PK), safety, and efficacy of oral MK-5172 (a fixed dose combination \[FDC\] tablet containing elbasvir \[EBR\] 50 mg and grazoprevir \[GZR\] 100 mg) and EBR/GZR (varying doses) pediatric granules in pediatric hepatitis C virus (HCV)-infected participants who are 3 to \<18 years of age. Within each age cohort (Cohort 1: 12 to \<18 years of age; Cohort 2: 7 to \<12 years of age; and Cohort 3: 3 to \<7 years of age), a Mini Cohort of 7 participants will be enrolled first. For the oldest cohort (Cohort 1), the Mini Cohort will assess ability to swallow a placebo tablet prior to administering active FDC tablets; participants in Cohorts 2 and 3 will take pediatric granules instead of a tablet.
