Summary

This is a randomized, open-label, parallel group, multicenter pilot study evaluating the efficacy and safety of alternative dosing of ribavirin vs. standard of care dosing in combination with peginterferon alpha-2a in interferon naïve patients with chronic hepatitis c genotype 1 infection.

Detailed description

The primary objective of the study is to demonstrate the efficacy and safety of (A) 2 weeks of high dose of ribavirin ("loading", ≥26 mg/kg/day for 14 days followed by ≥13 mg/kg/day) followed by concentration targeted (≥ 2.5 mg/L (10.25 μmol/L) 28 days after initiation of ribavirin therapy) dosing of ribavirin vs. (B) 4 weeks of ribavirin dosing before initiation of PEG-interferon dosing ("priming", ≥13 mg/kg/day) followed by concentration targeted (≥ 2.5 mg/L (10.25 μmol/L) 28 days after initiation of ribavirin therapy) dosing of ribavirin in combination with peginterferon alpha-2a in interferon naïve patients with chronic hepatitis C (CHC) virus genotype 1 infection as compared to (C) standard-of-care dosing of ribavirin (≥13 mg/kg/day without monitoring of ribavirin concentrations) in combination with peginterferon alpha-2a.

Conditions

• Hepatitis C

Interventions

Type	Name	Description
DRUG	Ribavirin "loading" dose given	PEG-IFN α-2a 180 μg/week plus loading (≥26 mg/kg/day for 2 weeks followed by ≥13 mg/kg/day) and concentration targeted (≥ 2.5 mg/L, i.e ≥ 10.25 μmol/L, as measured after 4 weeks of therapy) dosing of ribavirin and response guided treatment duration (RVR 24 weeks, non-RVR 48 weeks, pEVR consider 72 weeks), follow-up period 24 weeks
DRUG	"Priming" dose of ribavirin given	Standard-of-care dosing of ribavirin (≥13 mg/kg/day) without PEG-IFN for 4 weeks followed by 24-48 additional weeks of PEG-IFN α-2a 180 μg/week plus standard-of-care dosing of ribavirin (≥13 mg/kg/day) and concentration targeted (≥ 2.5 mg/L, i.e ≥ 10.25 μmol/L, as measured after 28 days after the initiation of ribavirin) dosing of ribavirin and response guided treatment duration (RVR 28 weeks, non-RVR 52 weeks, pEVR consider 76 weeks), follow-up period 24 weeks
DRUG	Group C ("Standard-of-Care")	PEG-IFN α-2a 180 μg/week plus standard-of-care dosing of ribavirin (≥13 mg/kg/day without any measurement of ribavirin concentration) and response guided treatment duration (RVR 24 weeks, non-RVR 48 weeks, pEVR consider 72 weeks), follow-up period 24 weeks
