# Analysis of real-world data demonstrating the efficacy of current management of polycythaemia vera in attaining and maintaining therapeutic haematocrit

## TL;DR

This study shows that current treatment methods for polycythaemia vera are effective in keeping patients' blood cell levels within a safe range.

## Contribution

The study provides real-world evidence supporting the effectiveness of current management guidelines for polycythaemia vera.

## Key findings

- Patients spent the majority of time within the target haematocrit range.
- Findings support the use of current management practices for polycythaemia vera.

## Abstract

Polycythaemia vera (PV) is a Philadelphia-negative myeloproliferative neoplasm, typically driven by acquired JAK2 mutation and characterised by elevated red cell mass and increased risk of thrombotic events. Patients are managed with phlebotomy to maintain haematocrit (Hct) < 0.45, and patients stratified as ‘high risk’ for thrombosis are additionally treated with cytoreductive agents to attain this target.

This analysis of newly diagnosed JAK2 mutant PV patients (n = 50) over 2 years aimed to determine how effectively patients attained and maintained target Hct according to recommended practice.

We found that patients spent the majority of time in target Hct range. Findings are supportive of current management guidelines.
