Role of Anti-CD38 Monoclonal Antibodies in the Treatment of Adult Immune Hematological Diseases

Daratumumab is a first-in-class human anti-CD38 IgG1 monoclonal antibody approved for treating newly diagnosed and relapsed refractory multiple myeloma. Pre-clinical data supported daratumumab's ability to deplete autoantibodies producing plasma cells, B-cells, and NK cells. Those reports showed promising results on using daratumumab in autoimmune disorders that are refractory to multiple lines of therapies, which encouraged using daratumumab in various autoimmune conditions that are refractory to standard therapies. This review aims to summarize the literature reporting experience using anti-CD38 antibodies in hematological autoimmune diseases, focusing on the most common autoimmune hematological diseases, including autoimmune hemolytic anemia, immune thrombocytopenia, posttransplant cytopenia, and pure red blood cell aplasia.
