CD19 CAR-T in the Treatment of Relapsed/Refractory Autoimmune Diseases

Summary

Autoimmune diseases such as systemic lupus erythematosus (SLE), diffuse cutaneous systemic sclerosis (dcSSc), antineutrophil cytoplasmic antibody (ANCA) -associated vasculitis (AAV), idiopathic inflammatory myopathy (IIM), and Sjogren's syndrome (SS) have complex etiologies and are prone to cause systemic multiple organ damage. Because patients need lifelong medication due to repeated disease recurrence, and the current treatment of the above autoimmune diseases has limited efficacy and greater side effects, so that patients bear an excessive burden of disease, therefore, there is an urgent need to explore safer and more effective treatment. Several autologous CAR-T products targeting CD19 have been marketed for the treatment of B-cell hematological malignancies. Depletion of B cells to suppress abnormal immune responses is also currently one of the popular strategies for the treatment of antibody-mediated autoimmune diseases, and many clinical studies of CAR-T against autoimmune diseases are still ongoing. Therefore, a dose escalation trial is planned to evaluate the safety, tolerability, and preliminary efficacy of autologous CD19 CAR-T in patients with relapsed/refractory autoimmune diseases.
