What are the Recent Developments in Global Evans Syndrome Market?

• In September 2025, Dr. Illiasul Ibad, a rheumatologist at Christian Medical College, published new clinical practice guidelines for Evans Syndrome. These guidelines emphasize the need for structured diagnosis, tailored immunosuppression, and thoughtful supportive care, moving beyond the traditional view of Evans Syndrome as merely a combination of immune thrombocytopenia (ITP) and autoimmune hemolytic anemia (AIHA)
• In June 2025, a consensus developed by the Red Blood Cell Diseases (Anemia) Group under the Chinese Society of Hematology within the Chinese Medical Association was published. This consensus aims to standardize the diagnosis and management of Evans Syndrome in China, addressing the lack of prospective evidence and randomized clinical trials for the disease in the country
• In March 2025, a study published in Internal Medicine reported that Rituximab, a monoclonal antibody, was effective in treating new-onset Evans Syndrome in patients also diagnosed with systemic lupus erythematosus (SLE) and lupus nephritis. This finding suggests that Rituximab may be a viable treatment option for patients with newly diagnosed Evans Syndrome, expanding therapeutic possibilities
• In October 2024, Dr. Emily Harris, a clinical fellow in pediatric hematology/oncology at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, received the Michael Blaese Research Grant Award. The grant, funded by the Immune Deficiency Foundation, supports her proposal to investigate Evans Syndrome, aiming to develop better diagnostic and treatment tools for this rare autoimmune disorder
• In July 2024, a pilot study published in PubMed reported that three patients with refractory autoimmune hemolytic anemia (AIHA) and Evans Syndrome achieved complete or partial remission after treatment with Orelabrutinib, a Bruton's tyrosine kinase inhibitor. This suggests that Orelabrutinib could become a new second-line treatment for relapsed/refractory AIHA and Evans Syndrome
