Triple Combination DAAs for Treating HCV GT1b Subjects

Phase 2
Withdrawn
Conditions
Chronic Hepatitis C Infection
Interventions
Drug: SOF+DCV+SMV
Registration Number
NCT02932293
Lead Sponsor
Humanity and Health Research Centre
Brief Summary

There is only one kind of treatment (simeprevir 150 mg + sofosbuvir 400 mg+daclatasvir 60 mg) in this study but the treatment duration may be different depending on patients' response to the antiviral therapy and whether patients have liver cirrhosis. If patients have no cirrhosis and the HCV viral load on day 2 is \<500 IU/ml, patients will receive sofosbuvir, daclatasvir and simeprevir for 3 weeks, otherwise the treatment duration is 4 weeks. If patients have cirrhosis and the HCV viral load on day 2 is \<500 IU/ml, patients will receive sofosbuvir, daclatasvir and simeprevir for 6 weeks, otherwise the treatment duration will be 8 weeks.

GroupInterventionDescription
SOF+DCV+SMV 6-8 wksSOF+DCV+SMVPatients with cirrhosis and CP-A will receive sofosbuvir, daclatasvir and simeprevir (a) 6 weeks if HCV VL on day 2 is \<500 IU/ml or (b) 8 weeks if HCV VL on day 2 is \>500 IU/ml.
SOF+DCV+SMV 3-4 wksSOF+DCV+SMVPatients without cirrhosis will receive sofosbuvir, daclatasvir and simeprevir for (a) 3 weeks if HCV viral load on day 2 is \<500 IU/ml or (b) 4 weeks if HCV viral load on day 2 is \>500 IU/ml.
Primary Outcome Measures
NameTimeMethod
Proportion of participants with plasma HCV viral load below the lower limit of quantification for 12 weeks after treatment completion (SVR12)Post treatment Week 12

SVR12 is defined as HCV RNA \< lower limit of quantification (LLOQ) 12 weeks after last dose of study drug.

Secondary Outcome Measures
NameTimeMethod
Frequency and severity of adverse eventsBaseline up to Week 24
Proportion of participants with unquantifiable HCV viral load at specified time points during and after treatmentBaseline up to Week 24
Kinetics of circulating HCV RNA during treatment and after treatment discontinuationBaseline up to Week 24
Proportion of participants with on-treatment virologic breakthrough and relapseBaseline up to Week 24

Viral breakthrough is defined as having achieved undetectable HCV RNA levels (HCV RNA \< LLOQ) during treatment, but did not achieve a sustained virologic response (SVR). Viral relapse is defined as having achieved undetectable HCV RNA levels (HCV RNA \< LLOQ) within 4 weeks of end of treatment, but did not achieve an SVR up to 24 weeks.
