Key Points

This research aims to compare the effects of ropeginterferon alfa-2b on phlebotomy outcomes among patients with polycythemia vera.
Conducted cross-study analyses of ropeginterferon alfa-2b treatment in polycythemia vera patients
Assessed treatment effects on phlebotomy requirements in low- and high-risk groups
Evaluated safety and tolerability of treatment regimens.
Ropeginterferon alfa-2b treatment led to significant reduction in v617f allele burden compared to slow titration
Patients experienced durable hematocrit (Hct) control and achieved phlebotomy-independence
Both treatment regimens were safe and well tolerated.

Implication

Cross-study analysis shows ropeginterferon alfa-2b enhances phlebotomy independence in polycythemia vera patients, suggesting effective intervention for diverse risk levels.

Abstract

V617F allele burden reduction than slow titration. Both regimens were safe and well tolerated. Ropeg treatment provides durable Hct control and phlebotomy-independence in a broad PV population, including high-risk patients.
