Market Overview: 

The 7 major warm autoimmune hemolytic anemia (WAIHA) markets reached a value of US$ 730.8 Million in 2024. Looking forward, IMARC Group expects the 7MM to reach US$ 3,486.9 Million by 2034, exhibiting a growth rate (CAGR) of 15.26% during 2024-2034.

The warm autoimmune hemolytic anemia (WAIHA) market has been comprehensively analyzed in IMARC's new report titled "Warm Autoimmune Hemolytic Anemia (WAIHA) Market: Epidemiology, Industry Trends, Share, Size, Growth, Opportunity, and Forecast 2024-2034". Warm autoimmune hemolytic anemia (WAIHA) is a rare autoimmune disorder characterized by the destruction of red blood cells by the body's immune system. The symptoms of the ailment can vary depending on the severity of the condition but typically include fatigue, weakness, shortness of breath, etc. Various other indications are pallor, jaundice, rapid heartbeat, dark urine, an enlarged spleen, etc. In severe cases, WAIHA can lead to acute hemolytic crisis, characterized by the sudden onset of anemia, and can be life-threatening. The diagnosis of WAIHA usually begins with a physical exam and medical history evaluation. A complete blood count (CBC) is the first step, which can reveal a low red blood cell count (anemia) and a high number of reticulocytes (young red blood cells). Various additional blood tests may be ordered to look for antibodies that attack red blood cells and rule out other causes of anemia. Besides this, a bone marrow biopsy is also performed to help confirm the diagnosis. Numerous imaging tests, such as ultrasound and CT scan, are done to check for an enlarged spleen, which is a common complication of WAIHA.

The rising cases of variations in genes that regulate immune system function are primarily driving the warm autoimmune hemolytic anemia (WAIHA) market. In addition to this, the increasing prevalence of several triggering factors, such as viral and bacterial infections, autoimmune diseases like lupus and rheumatoid arthritis, fluctuations in hormones, etc., is also bolstering the market growth. Moreover, the escalating utilization of intravenous immunoglobulin (IVIG) treatment, which involves infusing high levels of immunoglobulin into the bloodstream to control the autoimmune response and reduce the destruction of red blood cells, is acting as another significant growth-inducing factor. Apart from this, the widespread adoption of supportive therapies, such as iron supplementation, folic acid supplementation, erythropoietin, etc., to manage the symptoms of anemia and improve the quality of life in patients is further propelling the market growth. Additionally, numerous key players are making extensive investments in R&D activities to identify several potential pathways and molecules, including the B-cell receptor (BCR) signaling pathway and complement system proteins like C1s and C5, that could be targeted to treat WAIHA. This, in turn, is also creating a positive outlook for the market. Furthermore, the emerging popularity of rituximab for targeting and eliminating B cells in patients who do not respond to or cannot tolerate corticosteroids or immunosuppressants is expected to drive the warm autoimmune hemolytic anemia (WAIHA) market in the coming years.

This report is a must-read for manufacturers, investors, business strategists, researchers, consultants, and all those who have any kind of stake or are planning to foray into the warm autoimmune hemolytic anemia (WAIHA) market in any manner.

Recent Developments:

• In March 2024, HUTCHMED Limited announced that it had launched the registration stage of the Phase II/III clinical trial of sovleplenib in adult patients suffering from WAIHA in China. Sovleplenib is a novel, experimental, and selective small molecule inhibitor for oral administration that targets the spleen tyrosine kinase, or Syk.

Key Highlights:

• WAIHA is the most common form (60-70%) of autoimmune hemolytic anemia (AIHA).
• WAIHA is a rare condition affecting around 45,000 persons in the United States.
• WAIHA can affect people of any age, including children, but it is more common in adults, with a peak prevalence between 50 and 70 years.
• Depending on its causative factors, WAIHA can be classified as primary and secondary.
• Primary WAIHA is considered to be significantly less frequent than secondary WAIHA, with an estimated distribution of 35-50% of all WAIHA being primary instances.

Drugs:

Ianalumab is a fully human monoclonal antibody that targets BAFF-R. It possesses a new dual mechanism of action: it inhibits BAFF-R-mediated signaling while also effectively depleting B cells through antibody-dependent cellular cytotoxicity.

Rilzabrutinib is an oral, reversible, and covalent BTK inhibitor that can be a first- or best-in-class treatment for a variety of immune-mediated illnesses, including WAIHA. BTK, which is expressed in B and mast cells, plays a significant role in multiple immune-mediated disease processes.

Fostamatinib is an under-development potent, orally administered spleen tyrosine kinase inhibitor designed for the treatment of WAIHA. This therapeutic candidate has the potential to trigger a long-lasting increase in hemoglobin levels for some patients.
