Additional Details

This is a prospective, open-label, multicenter, randomized controlled clinical trial between Interferon Alfa and Pegylated Interferon Alfa-2b in adult essential thrombocythemia (≥18 years). Patients will be randomly divided into the following two treatment groups: 1. Recombinant Interferon Alpha, with an initial dose of 300 wu three times a week. Other interferons that have been listed can be used if Recombinant Interferon Alpha (300 wu) is not available. 2. Pegylated Interferon Alfa-2b, with an initial dose of 135 ug at week 0 , and then 180 ug once a week from week 1 to week 52. The dosage will be adjusted according to the results of laboratory examinations and patient tolerance. The patient will be transferred to the other group if intolerance or resistance occurs.
