Kite Pharma submits IND application for KITE-585 to FDA
Kite Pharma announced the submission of an Investigational New Drug application with the U.S. Food and Drug Administration to initiate a Phase 1, first-in-human trial of KITE-585, a CAR-T cell therapy engineered to target B-cell maturation antigen in patients with relapsed/refractory multiple myeloma. "KITE-585 has the potential to become Kite's next significant advance in cell therapy for patients with cancer. It is the result of an extensive preclinical development effort that included candidate screening, engineering, and testing by Kite's internal research team and it reflects the company's deep experience in CAR design and cellular therapeutics," said David Chang, M.D., Ph.D., Executive Vice President of Research and Development and Chief Medical Officer of Kite. "As we look ahead, we are confident that the cutting-edge design and manufacturing process of KITE-585 together with our proven capability with engineered T cells will support rapid execution of the clinical program." KITE-585 is an anti-BCMA CAR construct designed for high binding affinity to BCMA expressed on the cell surface. KITE-585 contains a receptor derived from a fully human monoclonal antibody and a CD28 costimulatory domain intended for optimized T-cell expansion and function. In preclinical studies, KITE-585 demonstrated activity across a range of low and high BCMA expressing targets and its activity was not impaired by soluble BCMA. In the presence of cell-bound BCMA, KITE-585 induced polyfunctional T cell expansion, and no tonic signaling in its absence. Advanced processes and materials used in the manufacturing of KITE-585 are designed to achieve enhanced cell potency.
