Use-Results Surveillance Study of Sovaldi® Plus Rebetol® in Japanese Patients With Chronic Genotype 2 Hepatitis C Virus Infection

July 28, 2017 updated by: Gilead Sciences

A Prospective Observational Post-Marketing Study of Sovaldi® Plus Rebetol® in Japanese Patients With Chronic Genotype 2 Hepatitis C Virus Infection

This use-results post-marketing surveillance (PMS) study for Sovaldi® tablets (sofosbuvir, SOF) administered in combination with Rebetol® capsules (ribavirin, REB) will evaluate the safety and efficacy of SOF administered in combination with ribavirin under real world use in Japan. Among adult patients with chronic genotype 2 hepatitis C virus (HCV) infection and treated with SOF+ribavirin in routine clinical use, the primary objective of this study is to evaluate the incidence of adverse drug reactions (ADRs) under real world settings.
