Idiopathic Thrombocytopenic Purpura Market Size, Epidemiology, In-Market Drugs Sales, Pipeline Therapies, and Regional Outlook 2026-2036

Market Overview:

The idiopathic thrombocytopenic purpura markets reached a value of USD 3.6 Billion across the top 7 markets (US, EU4, UK, and Japan) in 2025. Looking forward, IMARC Group expects the top 7 major markets to reach USD 5.5 Billion by 2036, exhibiting a growth rate (CAGR) of 3.86% during 2026-2036.

The idiopathic thrombocytopenic purpura market has been comprehensively analyzed in IMARC's new report titled "Idiopathic Thrombocytopenic Purpura Market Size, Epidemiology, In-Market Drugs Sales, Pipeline Therapies, and Regional Outlook 2026-2036". Idiopathic thrombocytopenic purpura (ITP), now known as Immune thrombocytopenic purpura, is a blood disorder characterized by low platelet counts, which can cause a variety of symptoms related to abnormal bleeding and bruising. Some of the most common indications include easy bruising, nosebleeds, prolonged bleeding after injury or surgery, bleeding gums, blood in urine or stool, petechiae (small red or purple spots on the skin), etc. In many cases, females with ITP may also experience heavy menstrual bleeding, excessive bleeding during childbirth, or bleeding in the brain, which can be life-threatening. The diagnosis typically involves a thorough medical history, physical examination, and blood tests to assess platelet counts. Various additional procedures, such as a bone marrow biopsy, may be recommended to confirm the prognosis or rule out further conditions. In some cases, several imaging tests are also used to check for bleeding or other complications related to low platelet counts. A diagnosis of ITP is typically made if a person has a platelet count of less than 100,000 per microliter of blood and no other underlying medical conditions that could cause thrombocytopenia.

The increasing prevalence of autoimmune disorders in which the immune system mistakenly attacks and destroys the blood platelets is primarily driving the idiopathic thrombocytopenic purpura market. Besides this, the rising incidence of several associated risk factors, such as viral and bacterial infections, certain medical conditions like lupus and rheumatoid arthritis, blood transfusions, etc., is also propelling the market growth. Furthermore, the widespread adoption of corticosteroids as a first-line treatment since they can rapidly improve platelet counts by suppressing the immune response that destroys platelets is creating a positive outlook for the market. Apart from this, the inflating demand for thrombopoietin receptor agonists, including romiplostim and eltrombopag, for increasing platelet counts in patients with chronic ITP who have not responded to other treatments is acting as another significant growth-inducing factor. Additionally, numerous key players are exploring the use of biomarkers to predict response to treatment and identify patients who are at risk of developing more severe forms of the disease. This, in turn, is further augmenting the market growth. Moreover, the emerging popularity of platelet growth factors, such as eltrombopag and romiplostim, which can aid in reducing the likelihood of bleeding incidences, is expected to drive the idiopathic thrombocytopenic purpura market in the coming years.

Recent Developments:

• In June 2024, HUTCHMED (China) Limited declared that The Lancet Haematology had published the findings of ESLIM-01, HUTCHMED's Phase III trial of sovleplenib (HMPL-523) in adult patients with primary immune thrombocytopenia (ITP) in China.
• In March 2024, Takeda reported positive topline results from a Phase 2 randomized, double-blind, placebo-controlled research that assessed the safety, tolerability, and efficacy of mezagitamab (TAK-079) in patients with persistent or chronic primary immune thrombocytopenia. Mezagitamab is a completely human immunoglobulin IgG1 monoclonal antibody (mAb) that has a high affinity for CD38-expressing cells (including plasmablasts, plasma cells, and natural killer cells), depleting them.
• In November 2023, Takeda reported that ADZYNMA (ADAMTS13, recombinant-krhn) has been approved by the U.S. FDA for the preventative and on-demand treatment of congenital thrombotic thrombocytopenic purpura (cTTP) in adults and children. ADZYNMA, the first and only FDA-approved recombinant ADAMTS13 (rADAMTS13) protein, addresses an unmet medical need in persons with cTTP by replacing the missing ADAMTS13 enzyme.
• In November 2023, argenx SE released topline results of the ADVANCE-SC study assessing VYVGART Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) in adults with primary immune thrombocytopenia (ITP).

Key Highlights:

• The annual incidence of ITP is around 5 cases per 100,000 children and 2 cases per 100,000 adults.
• In the United States, the annual incidence of ITP is estimated to be 3.3 per 100,000 people.
• In Europe, the annual incidence of ITP among adults is estimated to be between 1 and 4 per 100,000.
• Adults over the age of 60 have a higher prevalence of ITP because they are more likely to develop the disease's chronic form.
• ITP is most common in children between the ages of one and six years old.
• Approximately 0.5% to 1% of children suffering from ITP experience intracranial hemorrhage, and half of those cases lead to fatality.
