HCV Infection Clinical Trial

Official title: Pilot Therapeutic Study of DAA Treatment for Children and Adolescents With Active HCV Infection in Cambodia

Status Recruiting

Clinical Trial Summary

The goal of this clinical trial is to evaluate the effectiveness of sofosbuvir/daclatasvir combination for children aged ≥ 6 years old and adolescents with active HCV infection in Cambodia

Clinical Trial Description

Non-comparative multicenter pilot therapeutic prospective study conducted in Phnom Penh and Siem Reap and divided in 2 phases:

Screening phase:

First, all children aged more than 6 years old and adolescents under 18 years old will be screened for HCV infection using Bioline HCV rapid test in two paediatric populations in Phnom Penh and Siem Reap: 1/ children born from HIV/HCV co-infected women followed in OI/ART sites 2/ children hospitalized in paediatric department of Kantha Bopha Foundation Children's Hospitals and of the National Pediatric Hospital.

HCV RNA will be performed in case of HCV rapid test positivity. A case-control study will be performed to evaluate the risk factors associated to HCV acquisition. Cases will be defined as children with positive HCV RDT and controls as children with negative HCV RDT. Four controls will be randomly selected for one case.

Therapeutic phase:

Children and adolescents confirmed with active HCV infection (positive HCV RNA) during the first phase will be referred to a specific consultation in Kantha Bopha hospital or National Pediatric Hospital for treatment after evaluation of liver disease. Patients with a weight > 25 kg will be treated with a sofosbuvir/daclatasvir combination for 12 weeks with adult dose (400/60 mg), children with a weight between 14 and 25 kg will be treated with the same sofosbuvir/daclatasvir combination with the half adult dose (200/30 mg) for 12 weeks. For all children and adolescents, residual plasma concentrations (trough concentrations) of the drugs will be assessed after 2 weeks of treatment. For the first 20 children and adolescents included (10 children weighing between 14 and 25 kg and 10 weighing more than 25 kg), whatever their HIV status and ARV treatment, a complete pharmacokinetic analysis will be performed prior to drug administration and +1h, +2h, +6h and +10h after drugs intake. A non-compartimental analysis using Phoenix WinNonlin 8.1 (Certara, Princeton, NJ, USA) will be performed to estimate the pharmacokinetic parameters of sofosbuvir, GS-331007 and daclatasvir. Maximal concentration (Cmax), trough concentration at steady state (Ct), minimal concentration (Cmin) and the time required to reach Cmax (Tmax) are the observed parameters. The area under the curve (AUCtau) will be estimated by the linear up log down trapezoidal method using the predose concentration as 24-hour postdose concentrations. ;
