Clinical Trial Summary

A Study of Anti-CD19 Chimeric Antigen Receptor T Cell Therapy for Subjects With Refractory Lupus Nephritis

Description:

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by a wide spectrum of organ involvement and disease severity. Renal involvement (categorized as lupus nephritis [LN]) may occur in approximately 50% of SLE patients and is marked by proteinuria, microscopic hematuria, and varying degrees of renal insufficiency. B cells play a central role in the pathogenesis of SLE and LN, with autoantibodies developing as an early finding, and local, tissue resident B cells producing pathogenic autoantibodies and driving inflammation and tissue damage over time. CD19-targeted chimeric antigen receptor (CAR) T cells harness the ability of cytotoxic T cells to directly and specifically lyse target cells to effectively deplete B cells in the circulation and in lymphoid and potentially non-lymphoid tissues. KYV-101, a fully human anti-CD19 CAR T-cell therapy, will be investigated in adult subjects with refractory lupus nephritis.
