Summary
Brief summary (as posted)
Interferon alfa is an effective treatment of polycythemia vera (PV), but about 20% of patients discontinue their treatment because of side effects and treatment schedule (three times per week administration). The pegylated form of interferon alfa-2a has shown a better tolerance in hepatitis patients and is administered only once a week. The purpose of this study is to determine efficacy and safety of pegylated interferon alfa-2a in the treatment of PV patients.
