Current Environment:

Summary

This was a Phase 2/3, open-label, multicenter study to evaluate the pharmacokinetics (PK), efficacy, and safety of ombitasvir/paritaprevir/ritonavir (OBV/PTV/RTV) with or without dasabuvir (DSV) and with or without ribavirin (RBV) in Hepatitis C virus (HCV) genotype 1 or 4 (GT1 or GT4)-infected pediatric participants of ≥ 3 to 17 years of age.

Conditions

Chronic Hepatitis C Infection

Recruitment Status

Completed

Detailed Description

The study population for Part 1, the PK study, included GT1-infected participants who were noncirrhotic and treatment-naïve (TN). Part 2, the safety and efficacy study, included GT1 or GT4-infected participants who were TN or interferon ([IFN] or Pegylated-interferon alfa-2a or 2b [pegIFN] with or without RBV) treatment-experienced (TE) without cirrhosis or with compensated cirrhosis. In Part 1 and Part 2, the treatment regimen and duration were dependent on HCV GT, GT1 subtype, and cirrhosis status.

Eligibility Criteria

Inclusion Criteria:

Parent or legal guardian with the willingness and ability to provide written informed consent and participant willing and able to give assent, as appropriate for age and country

Exclusion Criteria:

Female participant who is pregnant, breastfeeding or is considering becoming pregnant
