简要总结
The goal of this clinical trial is to evaluate the efficacy and safety of Gecacitinib in combination with pegylated interferon for the treatment of polycythemia vera (PV).The main question it aims to answer is:
Can PV patients achieve hematological remission after receiving the combination therapy?
Participants will:
Receive combination treatment with Gecacitinib Hydrochloride Tablets and pegylated interferon for 24 weeks Visit the hospital regularly for examinations and follow-up assessments
