Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Adult tablet, 12-17 yr, Part 1

Participants with HCV GT1b without cirrhosis received the adult 3-DAA (OBV/PTV/RTV and DSV) regimen: two 12.5 mg ombitasvir /75 mg paritaprevir /50 mg ritonavir tablets taken orally every morning (QD) and one dasabuvir 250 mg tablet taken orally twice a day (BID) for 12 weeks. Participants with HCV GT1a without cirrhosis received 12-week treatment with the adult 3-DAA regimen and ribavirin 200 mg tablets were administered orally per local label.

Adult tablet, 12-17 yr, Part 2

Participants with HCV GT1b received the adult 3-DAA (OBV/PTV/RTV and DSV) regimen: two 12.5 mg ombitasvir /75mg paritaprevir /50 mg ritonavir tablets taken orally every morning (QD) and one dasabuvir 250 mg tablet taken orally twice a day (BID) for 12 weeks. Participants with HCV GT1a without cirrhosis received 12-week treatment with the adult 3-DAA regimen and ribavirin 200 mg tablets were administered orally per local label. Participants with HCV GT1a with compensated cirrhosis received 24-week treatment with the adult 3-DAA regimen and ribavirin 200 mg tablets were administered orally per local label. Participants with HCV GT4 received 12-week treatment with the OBV/PTV/RTV formulation and ribavirin 200 mg tablets were administered orally per local label.

Mini tablet, 9-11 yr, Part 1

Participants with HCV GT1b without cirrhosis were to receive the mini-tablet 3-DAA (OBV, PTV, RTV, and DSV) regimen for 12 weeks: ombitasvir 0.3 mg, paritaprevir 1.0 mg, and ritonavir 1.0 mg mini-tablets administered orally QD based on body weight and dasabuvir taken orally BID as 3.08 mg mini-tablets based on body weight. Participants with HCV GT1a without cirrhosis received 12-week treatment with the mini-tablet 3-DAA regimen and ribavirin was provided as a 40 mg/mL oral solution and administered per local label.
