Clinical Trial Summary

Study purpose: To compare the efficacy and safety of pegylated interferon α-2b in combination with ruxolitinib versus pegylated interferon α-2b alone for treating hydroxyurea-resistant or hydroxyurea-intolerant polycythemia vera.


Clinical Trial Description

Study purpose: To compare the efficacy and safety of pegylated interferon α-2b in combination with ruxolitinib versus pegylated interferon α-2b alone for treating hydroxyurea-resistant or hydroxyurea-intolerant polycythemia vera. The subjects will be randomly divided into two groups: pegylated interferon alpha-2b combined with ruxolitinib group: pegylated interferon alpha-2b at a starting dose of 180ug will be administered subcutaneously once a week; ruxolitinib at a starting dose of 10mg will be administered orally twice daily. pegylated interferon alpha-2b group: pegylated interferon alpha-2b at a starting dose of 180ug will be administered subcutaneously once a week. If complete hematologic remission is not achieved after 12 weeks of treatment with pegylated interferon alpha-2b alone, the subject may be switched to the pegylated interferon alpha-2b combined with ruxolitinib group. If ruxolitinib is not tolerated, the subject may be switched to the pegylated interferon alpha-2b group alone. ;
