Autoimmune hemolytic anemia (AIHA)
Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against the person's own red blood cells (RBCs) cause them to lyse, leading to an insufficient number of oxygen-carrying red blood cells in the circulation

Autoimmune hemolytic anemia (AIHA) is an acquired, heterogeneous group of diseases which includes warm AIHA, cold agglutinin disease (CAD), mixed AIHA, paroxysmal cold hemoglobinuria and atypical AIHA.
Autoimmune hemolytic anemia (AIHA) occurs when antibodies directed against red blood cells (RBCs) lyse, leading to an insufficient number of oxygen-carrying red blood cells in the circulation. The lifetime of the RBCs is reduced from the normal 100–120 days to just a few days in serious cases.†

Title | Description | Phases | Status | Interventions | More Information |
---|---|---|---|---|---|
Acalabrutinib for the Treatment of Relapsed or Refractory Autoimmune Hemolytic Anemia in Patients With Chronic Lymphocytic Leukemia | This phase II trial studies the effect of acalabrutinib in treating autoimmune hemolytic anemia that has come back (relapsed) or has not responded to previous treatment (refractory) in patients with chronic lymphocytic leukemia. Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. | Phase 2 | Recruiting | Drug: Acalabrutinib | Click here for more information |
