Status Recruiting

Clinical Trial Summary

This is an interventional Phase II/III, single center, single arm clinical trial to assess the pharmacokinetics, efficacy, safety and tolerance of daclatasvir plus sofosbuvir in treatment-naïve, non-cirrhotic adolescents with chronic HCV GT-4 infection.

A single-arm evaluation of daclatasvir/sofosbuvir will focus on the pharmacokinetics, efficacy and safety

All enrolled patients will receive daclatasvir 60 mg orally once daily plus sofosbuvir at a dose of 400 mg orally once daily for 12 weeks.

Clinical Trial Description

This is an interventional Phase II/III, single center, single arm clinical trial to assess the pharmacokinetics efficacy, safety, and tolerance of daclatasvir plus sofosbuvir in treatment-naïve, non-cirrhotic adolescents with chronic HCV GT-4 infection.

A single-arm evaluation of daclatasvir/sofosbuvir will focus on the efficacy, safety and pharmacokinetics, confirm the favorable pharmacological profile.

All enrolled patients will receive daclatasvir 60 mg orally once daily plus sofosbuvir at a dose of 400 mg orally once daily for 12 weeks.

Patients will be followed closely for disease progression and any hypersensitivity or adverse reactions due to therapy. Laboratory values to be monitored at baseline: Serum creatinine, bilirubin, AST, ALT, HCV viral load (VL).

Fifty patients will be included; the first twenty patients will be candidates for pharmacokinetic assessment. All patients (50), will be candidates for safety and efficacy assessment after verifying the PK results ''phase II''. Patients will be recruited at Ain Shams University hospitals, Egypt. The study will be conducted after approval of the corresponding research ethical committee and obtaining an informed consent from the parents/guardians and an assent from the patients.

Patients will be requested to come for 2 screening visits, at the first day of therapy, weekly during the first four weeks, at the end of week 8 and week 12. Patients who will complete their treatment schedule will be scheduled for a visit after 12 weeks from end of therapy for assessment of sustained virological response (SVR). The total number of visits are 9. Duration of follow up will be 24 weeks from treatment initiation in addition to the screening period (2-4 weeks). ;
