Burden of thromboembolism, disease progression, and phlebotomy among polycythemia vera patients in the United States: a systematic literature review

Polycythemia vera patients face substantial blood clots and progression risks annually, underscoring the need for better treatments beyond current phlebotomy approaches.

This systematic review of 35 US-based PV studies quantifies the substantial burden: 1.4-6.5 annual TEs per 100 patients, myelofibrosis progression in up to 20%, and phlebotomy-linked QoL impairment, highlighting significant unmet treatment need. The review was funded by Takeda Pharmaceuticals — relevant conflict of interest for interpreting conclusions about treatment gaps.
