Population Pharmacokinetics of Ledipasvir/Sofosbuvir in Pediatric Patients: Impact of Acute Lymphoblastic Leukemia.

Purpose: The pharmacokinetic (PK) profile of direct-acting antivirals, namely ledipasvir/sofosbuvir (LDV/SOF), might be altered in patients with acute lymphoblastic leukemia (ALL), affecting the optimum dose needed for hepatitis C virus treatment. Limited data are available evaluating the population PK of LDV/SOF and SOF metabolite GS-331007. We aimed to study whether ALL could affect population PK parameters of LDV, SOF, and the SOF major metabolite GS-331007 in hepatitis C virus-infected children, develop and validate a predictive PK model of LDV/SOF disposition in this special population, and identify their explained and unexplained sources of variability.

Ledipasvir/Sofosbuvir in Hepatitis C Virus-Infected Children With Hematological Malignancies: A Pharmacokinetic Study.

Purpose: Children with hematological malignancies and chronic hepatitis C virus (HCV) infection are at a higher risk for rapid progression of liver disease and malignancy relapse due to multiple hepatitis flares and chemotherapy interruption. They are therefore potential candidates for microelimination of HCV infection. This study aimed to assess the effect of acute lymphoblastic leukemia (ALL) on the pharmacokinetic (PK) profile of direct-acting antivirals, namely ledipasvir/sofosbuvir (LDV/SOF) and the SOF major metabolite GS-331007.
