Brief Summary:

This is a prospective, controlled, open-label, pharmacokinetic study. This study aims at studying the PK of sofosbuvir, ledipasvir and sofosbuvir metabolite (GS-331007) in HCV infected children with hematological Disorders. to develop predictive pharmacokinetic model for the 3 moieties in the studied population.

In this study, patients in both treatment groups will receive 12 weeks of treatment with a fixed-dose combination tablet containing 400 mg of sofosbuvir and 90 mg of ledipasvir(SOF/LED) orally, once daily with food.


Condition or disease Intervention/treatment Phase
HCV Infection Beta Thalassemia Major Drug: Sofosbuvir and Ledipasvir Phase 3

Detailed Description:

In this study, patients in both treatment groups will receive 12 weeks of treatment with a fixed-dose combination tablet containing 400 mg of sofosbuvir and 90 mg of ledipasvir(SOF/LED) orally, once daily with food, as prescribed by the attending physician. Twelve eligible HCV-infected patients with hematological disorder and 12 matching HCV control patients without haematological disorder or comorbidities will be enrolled in the study. At baseline, careful history of the recruited patients including demographic characteristics (age, height, weight, and gender), comorbidities, medication history, familial history, social history, blood transfusion history, and baseline laboratory tests will be documented.

The baseline laboratory tests will include renal function tests (serum creatinine), liver function tests (bilirubin, albumin, AST, and ALT), international normalised ratio (INR), alpha fetoprotein (AFP), complete blood count (CBC), degree of liver fibrosis by Fibroscan,viral load by PCR and HCV genotype Follow-up will be done for all participants at baseline, after 10 days of treatment for the evaluation of the steady state PK parameters of SOF/LED in those patients, after 12 weeks of treatment, and after 12 weeks from the end of treatment. For a total of 4 follow-up visits.
