Polycythemia Vera - Market Insight, Epidemiology, and Market Forecast - 2036

Polycythemia Vera Insights and Trends

• Most Polycythemia Vera patients are symptomatic, with approximately ~91,000 patients with JAK2 mutation in the United States in 2025.
• In 2025, the market size of Polycythemia Vera was highest in the United States among the 7MM, accounting for approximately ~USD 1,500 million, which is further expected to increase by 2036, owing to the launch of emerging therapies, assisted by an increase in the diagnosed prevalent population of Polycythemia Vera.
• The cornerstone of treatment for Polycythemia Vera remains phlebotomy to maintain safe hematocrit levels, often combined with low-dose aspirin. High-risk patients may also receive cytoreductive therapy, such as hydroxycarbamide (hydroxyurea). Ruxolitinib (JAKAFI) and rRopeginterferon alfa-2b (BESREMi) are approved in the US, Europe, and Japan, with Ruxolitinib (JAKAFI) established as a standard second-line therapy since 2015. PEGASYS (peginterferon alfa-2a) received marketing authorization in 2024 and formal approval in the UK in 2025, building on prior off-label use.
• Since BESREMi's label is broad (first and subsequent lines of therapy), PharmaEssentia has more leeway in positioning BESREMi in diverse therapeutic situations. Given BESREMi's position upstream of JAKAFI in the NCCN recommendations, the drug is not a direct competitor for JAKAFI. Still, it has the potential to hinder the progression of patients to JAKAFI usage, which might affect JAKAFI's overall revenue.
• The patent expiration in mid-2028 might be the most significant obstacle to JAKAFI's supremacy in the Polycythemia Vera market. To address this, Incyte introduced the LIMBER (Leadership in MPNs and GVHD beyond Ruxolitinib) life-cycle management initiative, which was meant to explore different monotherapy and combination methods to enhance and expand therapies for patients with MPNs and GVHD.
• Other emerging Polycythemia Vera therapies in development include Bomedemstat (LSD1 inhibitor, Merck), Sapablursen (TMPRSS6 inhibitor, Ionis Pharmaceutical/Ono Pharmaceutical), Divesiran (TMPRSS6 inhibitor, Silence Therapeutics), PPMX-T003 (anti-TfR1, Perseus Proteomics), and DISC-3405 (anti-TMPRSS6, Disc Medicine), and others highlighting a growing pipeline of innovative treatments.
• Several other potential therapies for Polycythemia Vera are in the early stage of development, which include INCB160058 (Incyte), AG-236 (Agios Pharmaceuticals and Alnylam Pharmaceuticals, Phase I), VGT-1849A and VGT-1849B (Vanda Pharmaceuticals, NA), JAK2V617F (Prelude Therapeutics and Incyte, IND enabling), PN-8047 (Protagonist Therapeutics, IND enabling), and others.

Polycythemia Vera Understanding and Treatment Algorithm

Polycythemia Vera Overview and Diagnosis

Polycythemia Vera is a rare condition characterized by the progressively increased number of red blood cells in the bloodstream, white blood cells (WBC), and platelets also increase in number in the affected people. Polycythemia Vera is the most common myeloproliferative neoplasm (MPN). Out of all the MPNs, Polycythemia Vera is the most common and the only one in which there is an increase in RBC production. Polycythemia Vera usually occurs at an elderly age, and patients are at a higher risk than the usual percentage, as they are more prone to risks and other comorbidities.

Polycythemia Vera Diagnosis

The diagnosis of Polycythemia Vera is based on results from tests assessing elevations in blood counts and the presence of molecular mutations associated with the disease. The initial evaluation should include a focused clinical history, physical examination, hematocrit concentration, and count of RBC, WBC, platelets, serum EPO level, and cytogenetic abnormalities. The patient's journey begins with a referral to a hematologist. However, the current approach to diagnosing these patients is quite similar, as most developing countries establish a patient's diagnosis journey using WHO criteria, which is based on a composite assessment of clinical and laboratory features, including JAK2 mutation status and serum erythropoietin level. However, when it comes to analyzing the real-world scenario in varying geographies, there are some differences in diagnostic criteria and risk stratification that other organizations in certain European countries have proposed.

For example, even though the WHO classification considers histology useful in distinguishing Polycythemia Vera from other myeloproliferative neoplasms (MPNs), the British Society for Haematology Guideline has also cited several studies that have reported high rates of failure to reach a histological diagnosis in patients with Polycythemia Vera.

Polycythemia Vera Treatment

Based on real-world pattern analysis, patients suffering from Polycythemia Vera receive treatment with certain drugs (myelosuppressive drugs) that suppress the formation of blood cells by the marrow. A chemotherapy drug, hydroxyurea, is most often used, along with another chemotherapy drug known as busulfan. Other drugs, such as chlorambucil and radioactive phosphorus, have also been used. JAKAFI and BESREMi are the two FDA-approved drugs for treating Polycythemia Vera.

Although medication adherence can be elusive, it has been found that the patients who were prescribed injectable cytoreductive drugs had lower adherence rates than their counterparts taking oral formulations. There are many factors when it comes to lower adherence to therapies, for instance, when patients are taking too many therapies together, facing side effects, having cost concerns, and facing issues with dosing regimens.

Polycythemia Vera Unmet Needs

The section "unmet needs of Polycythemia Vera" outlines the critical gaps between the current state of patient care, diagnosis, and the ideal & effective management of the disease. It highlights the obstacles experienced by patients, clinicians, and researchers and identifies potential solutions for future progress.

JAKAFI/JAKAVI is an oral inhibitor of the JAK 1 and JAK 2 tyrosine kinases. It is approved for treating adult patients resistant to or intolerant of hydroxyurea. Incyte's flagship product, JAKAFI, received approval as a second-line therapy for Polycythemia Vera patients in December 2014 in the United States, followed by approvals in both the EU and Japan in 2015.

In December 2024, the American Society of Hematology (ASH) Annual Meeting and Exposition featured novel research on the long-term safety and efficacy of ruxolitinib for patients with polycythemia vera. The poster presentations in particular shed light on the superiority of ruxolitinib over hydroxyurea and how ruxolitinib can allow patients to rely less on corticosteroids.

Polycythemia Vera Pipeline Analysis

Rusfertide (PTG-300): Protagonist Therapeutics

Rusfertide is a novel injectable synthetic mimetic of the natural hormone hepcidin that offers greater potency, solubility, and stability, which translates to better in vivo pharmacokinetics and pharmacodynamics characteristics and manufacturability in comparison to the natural hormone. In December 2024, the final results of rusfertide from the Phase II REVIVE trial were presented at the ASH (4559) meeting. The data demonstrated that rusfertide, when added to therapeutic phlebotomy with or without cytoreductive therapy, effectively controlled erythrocytosis, provided long-term durable control of hematocrit, and reduced the need for therapeutic phlebotomy in patients with Polycythemia Vera.

According to Protagonist Therapeutics' corporate presentation published in January 2026, the company filed an NDA for rusfertide in 2025, with an anticipated early launch in H2 2026.

Polycythemia Vera Market Outlook

Polycythemia Vera treatment in the US is entering a new era with changing dynamics. Therapeutic options for Polycythemia Vera are limited, and no cure is available. The treatment landscape was dominated by legacy, generic therapies such as Hydroxyurea, second-generation interferon, and Phlebotomy until the approval of BESREMi as both the first and second line of treatment, and JAKAFI in the second line of treatment only; options for third-line treatment are still limited. Adding to that, Low-dose aspirin and phlebotomy are recommended as first-line treatment options for patients at low risk of thrombotic events. Cytoreductive therapy (usually hydroxyurea or interferon alpha) is recommended for high-risk patients. Polycythemia Vera treatment is still inadequate, as approximately 30% of Hydroxyurea-treated patients become resistant/intolerant.

The current market has been segmented into different commonly used therapeutic classes based on the prevailing treatment pattern across the 7MM, which presents minor variations in the overall prescription pattern. JAK inhibitor, Interferons, Hepcidin mimetic, TMPRSS6 inhibitor, CK1a, BCL-2 inhibitor, and LSDI inhibitor are the major classes covered in the forecast model.

Key players involved in developing targeted therapies to treat Polycythemia Vera include Protagonist Therapeutics and Takeda Pharmaceuticals (rusfertide), Merck (bomedemstat), Italfarmaco (givinostat), Ionis Pharmaceuticals and Ono Pharmaceutical (sapablursen), Silence Therapeutics (Divesiran (SLN124)), Perseus Proteomics (PPMX-T003), Disc Medicines (DISC-3405), and others are evaluating their lead candidates in different stages of clinical development, respectively. They aim to investigate their products for the treatment of Polycythemia Vera.

• The total market size of Polycythemia Vera in the 7MM is approximately ~USD 2,000 million in 2025 and is projected to increase during the forecast period (2026-2036).
• Among EU4 and the UK, Germany accounts for the maximum market size in 2025, while the United Kingdom occupies the bottom of the ladder in 2025.
• In 2025, among the current therapies for Polycythemia Vera, the largest revenue was generated by JAKAFI, i.e., ~USD 1,000 million in the United States.
• By 2036, among all the emerging therapies in the EU4 and the UK, the highest revenue is expected to be generated by Rusfertide.

Drug Class/Insights

The existing Polycythemia Vera treatment is mainly dominated by classes such as antimetabolites, platelet-reducing agents, Interferons, and JAK inhibitors.

JAK inhibitors have been developed following the discovery of the JAK2V617F in 2005 as the driver mutation of most non-BCR-ABL1 MPNs. A decade after the beginning of clinical trials, only one JAK inhibitor, JAKAFI, has been approved by the US Food and Drug Administration for hydroxyurea-resistant or intolerant Polycythemia Vera patients since 2014. JAKAFI competes with platelet-reducing agents (Anagrelide), Interferon alpha, and BESREMi in the second line of treatment. Even though there are safety concerns regarding JAK inhibitors, we cannot misconstrue the strong uptake of JAKAFI in the already treated patients with this blood disorder.

Moving on to Interferon's, BESREMi is not the first one being used in these patients, though it is the first approved interferon for Polycythemia Vera patients. For years, PEGASYS has been commercially available, which is present all along. PEGASYS is a form of pegylated interferon that is used off-label by patients living with a myeloproliferative neoplasm. However, many patients have dealt with access and reimbursement issues, as it is accessed off-label.

Moreover, the upcoming treatment landscape is poised to see further expansion after the emergence of new classes such as iron modulator, LSD1 inhibitor, Pan-HDAC inhibitor, TMPRSS6 inhibitor, TfR targeting, BCL-2 inhibitor, Immunostimulant, CK1a, and others.

Polycythemia Vera Drug Uptake

This section focuses on the uptake rate of potential drugs expected to be launched in the market during 2022-2036. For example, for Rusfertide, although the FDA rescinded its Breakthrough Designation, we expect the drug uptake to be medium-fast with a probability-adjusted peak share of 5.7% in the first line and second line, and years to the peak are expected to be 7 years from the year of launch. The drug was proven to be better among all the other therapies in terms of safety and efficacy.

Polycythemia Vera Therapies Price Scenario & Trends

Pricing and analogue assessment of Polycythemia Vera therapies highlights evolving price dynamics structures. This section summarizes the cost of approved treatments, closest and most appropriate analogue selection for emerging therapies, and understanding of how pricing influences market access, adherence, and long-term uptake.

• Pricing of Polycythemia Vera Approved Drugs

Recommended starting dose of BESREMi is 100 mcg by subcutaneous injection every 2 weeks (50 mcg if receiving hydroxyurea). Further increasing the dose by 50 mcg every 2 weeks (up to a maximum of 500 mcg) until hematological parameters are stabilized. Hence, on this basis we have assumed 22 syringes would be needed in a year. PharmaEssentia launched BESREMi at a wholesale acquisition cost (WAC) of USD 6,988 per syringe, translating to an annual cost of USD 153,736
