Stop Progression of Fibrosis by Administration of Intermittent Continuous Treatment With Peginterferon Alfa-2a. Open-label, Randomized Efficacy and Safety Clinical Trial of Intermittent Continuous Treatment With Peginterferon Alfa-2a (PEGASYS) in Patients With HBeAg Negative Hepatitis B Responding to Prior Treatment With Interferon Alfa (SOFIA -LTT)
In Brief
A Phase 2 clinical trial evaluating PEGASYS [peginterferon alfa-2a] for Hepatitis B, Chronic. Completed, enrolled 21 participants across 1 site.
Detailed Summary
This 2 arm study will evaluate the efficacy and safety of intermittent treatment with PEGASYS in HBeAg negative patients with chronic hepatitis B who have demonstrated virological and biochemical response after treatment with interferon alfa. After 48 weeks therapy with interferon alfa, and 24 weeks treatment-free follow-up, eligible patients will be randomized into the PEGASYS or the observational group. Those in the PEGASYS group will receive 4 therapeutic cycles of long term intermittent treatment with PEGASYS (135 micrograms sc weekly for 12 weeks, followed by a treatment-free period of 12 weeks) and those in the observational arm will receive no specific antiviral treatment. The anticipated time on study treatment is 1-2 years, and the target sample size is 100 individuals.
