Abstract
Background: Polycythemia vera (PV) is characterized by erythrocytosis and an increased risk of thrombotic events (TEs). Currently, standard-of-care therapies for PV have limitations, which indicate the need to understand real-world treatment patterns and treatment burden in PV.
Research design and methods: This retrospective observational study analyzed real-world claims data in adult patients with PV using the Komodo Health claims database (2016-2022) in the United States. Burdensome treatment was classified as patients receiving ≥ 3 phlebotomies (PHLs) within a 6-month period and/or high-dose hydroxyurea (HU) ≥ 1,000 mg per day.
Results: Of 44,766 treated patients (mean age: 65 years; 64% male), 55% received burdensome treatment, which included frequent PHL (33%), high-dose HU (17%), or a combination of both (frequent PHL + high-dose HU, 5%). PHL and HU were the most common first-line treatments (PHL, 71%; HU, 27%), and 87% of patients initiating treatment with PHL monotherapy never advanced to another therapy regimen. TEs occurred in 16% of the treated patients.
Conclusions: These data suggest a substantial proportion of patients with PV receive burdensome treatments, with 55% of treated patients receiving frequent PHL and/or high-dose HU, highlighting need for therapy optimization. However, inherent limitations of using claims data should be taken into consideration.
期刊介绍:
Advanced molecular research techniques have transformed hematology in recent years. With improved understanding of hematologic diseases, we now have the opportunity to research and evaluate new biological therapies, new drugs and drug combinations, new treatment schedules and novel approaches including stem cell transplantation. We can also expect proteomics, molecular genetics and biomarker research to facilitate new diagnostic approaches and the identification of appropriate therapies. Further advances in our knowledge regarding the formation and function of blood cells and blood-forming tissues should ensue, and it will be a major challenge for hematologists to adopt these new paradigms and develop integrated strategies to define the best possible patient care. Expert Review of Hematology (1747-4086) puts these advances in context and explores how they will translate directly into clinical practice.
