Study 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.

Read the detailed 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).

    Daclatasvir and sofosbuvir Single arm intervention open label trial for single tablet (Daclatasvir 90 mg and Sofosbuvir 400mg and ) Daclatasvir 90 mg for 12 weeks

    Drug: Daclatasvir and sofosbuvir

Interventions

  • DrugDaclatasvir and sofosbuvir

    Daclatasvir is a DAAs that can inhibit the HCV non-structural (NS) 5A protein when used in combination with other HCV-therapies. It has a linear, non-time-dependent pharmacokinetic profile and nanomolar potency in vitro against HCV genotypes 1-6. It is excreted primarily via faeces, about 88% in an unchanged form while renal excretion accounts for approximately 7% of its elimination. DOSE OF SOFOSBUVIR: 400 mg tablet orally once daily with food (in the morning) for 12 weeks for adolescents with liver fibrosis Metavir score F0-F2. DOSE OF DACLTASVIR: 60 mg tablet orally once daily with food (in the morning) for 12 weeks for adolescents with liver fibrosis Metavir score F0-F2.

    Also known as: DCV-SOF, Sofosbuvir-Daclatasvir

What researchers measure

Primary outcomes

  1. Measurement of the pharmacokinetics of DCV-SOF

    Blood samples (3 mL) will be collected to measure dactalasvir concentrations from pediatric patients using a nine-point plasma schedule (pre-dose, 0.5,1, 2, 4, 8, 12, and 24 h post-dose) on day 8 of therapy. (This will be a total of 27 mL/patient, which is well below the maximum allowed internationally recognized value of blood loss is 2.4mL/kg in a 4 month period. Any deviations from nominal sampling times should be recorded. AUCtau which is defined as the concentration of drug over time (area under the plasma concentration versus time curve over the dosing interval will be calculated

    Time frame: Blood samples will be collected on day 8 of therapy

Secondary outcomes

  1. Measurement of Number of Participants With sustained virological response (SVR12), 12 weeks after discontinuation of therapy with daclatasvir-sofosbuvir (DCV-SOF).

    Number of Participants With sustained virological response at 12 Weeks after end of study drug treatment (SVR12) will be recorded, participant will be considered to have achieved SVR12 if HCV RNA is less than the lower limit of quantification of \<15 IU/ml) at 12 weeks after the end of treatment.

    Time frame: 12 weeks after discontinuation of therapy with daclatasvir-sofosbuvir (DCV-SOF).
