Real life data on elbasvir/grazoprevir efficacy, safety and drug-drug interaction profile in patients with chronic hepatitis C viral infection: a prospective analysis in the PITER cohort

Introduction: In a previous study, based on PITER cohort data, it was reported that of patients, undergoing direct acting antiviral (DAA) therapy, 30%-44%, are at risk of potential drug-drug interactions (DDI). Aim: We aimed to evaluate the prospective profile of elbasvir/grazoprevir (EBR/GZR) efficacy and safety combined with real life comedication profile. Method: Data from 312 patients (mean age 63 ± 10 years; 44% male, 90% of genotype 1.85% fibrosis stage ≤ F3, 15% with child A cirrhosis), enrolled in PITER by 15 clinical centers and treated with EBR/GZR, with at least three months of follow up after the end of treatment, were evaluated. Comedication profiles (no changes, drugs interrup…
