  Purpose

This randomized, single blind study will compare the antiviral effect of Pegasys (pegylated interferon alfa-2a) plus placebo versus Pegasys plus tenofovir in pa tients with chronic hepatitis D. Patients will be randomized to receive 96 weeks of therapy with Pegasys (180 micrograms sc weekly) plus either placebo (orally daily) or tenofovir (245mg orally daily). Anticipated time on study treatment is 2+ years, target sample size is <50.
