An Observational Study on the Prevalence of Chronic Hepatitis D in Romania and the Efficacy of Treatment With Pegasys (Peginterferon Alfa-2a)

November 1, 2016 updated by: Hoffmann-La Roche

National, Multicenter, Observational Study Evaluating Prevalence, Virological and Clinical Characteristics of Chronic Hepatitis Delta in Romania and Assess Efficacy of Peg-interferon Alfa-2a Treatment in Patients With Chronic Hepatitis D (CHD)

This prospective, multicenter, observational study will assess the prevalence of chronic hepatitis D in patients with chronic hepatitis B in Romania and evaluate the efficacy of Pegasys (peginterferon alfa-2a) in patients with chronic hepatitis D. Eligible patients treated with Pegasys according to current medical practice will be followed until 24 weeks after the end of treatment.
