Immune Thrombocytopenia (ITP) Drug Development

Creative Biolabs is a drug discovery CRO that has many years of experience in the development of drugs for autoimmune diseases. Our diverse drug development platforms include monoclonal antibody development, bispecific antibody development, and cell-based therapy development.

Immune thrombocytopenia (ITP) is one of the best characterized autoimmune diseases. Both antibody-mediated and/or T cell-mediated platelet destruction and impairment of platelet production are key processes. For patients with ITP, the persistently low platelet counts present real and perceived risks for serious and even fatal bleeding events and may therefore require emergency department visits and hospitalization.

Treatment of ITP

First-line treatments focus on the inhibition of autoantibody production and platelet degradation, including corticosteroids with or without intravenous IVIg and anti-D. Second-line therapies consist of splenectomy and/or immunosuppressive drugs such as the B cell-depleting anti-CD20 antibody drug. Thrombopoietin (TPO)-receptor agonists are considered third-line treatments which aim to stimulate platelet production by megakaryocytes.

B cells play a crucial role in both the development and perpetuation of autoimmunity, suggesting that B cell depletion could be a valuable treatment approach for patients with ITP. Therefore, a low-dose anti-CD20 antibody drug, combined with short-term glucocorticoids, provides an effective treatment for ITP to improve long-term outcomes without compromising the safety profile. The use of anti-CD20 antibody drugs could create complete B cell depletion and revert the abnormalities of Treg cells. Additionally, patients with active ITP have a defective T regulatory cell compartment modulated by a B cell-targeted therapy, which is a potential treatment option.
