|Kite Presents Promising Preclinical Data from KITE-585, a Fully Human Anti-BCMA CAR T-Cell Product Candidate at the 2017 American Association of Cancer Research (AACR) Annual Meeting|
In today's oral presentation (Abstract #4979), "Development of KITE-585: A fully human anti-BCMA CAR T-cell therapy for the treatment of multiple myeloma," KITE-585 demonstrated potent in vitro and in vivo activity against MM cell lines. CAR T cells were active in the presence of soluble BCMA and also eradicated established MM tumors in mice. KITE-585 contains a proprietary linker with the CD28 costimulatory domain. This configuration resulted in polyfunctional activation and proliferation of T-cells in the presence of MM cell lines, with no evidence of tonic signaling in the absence of target cells.
In the poster presentation (Abstract #2135), "Selectivity and specificity of engineered T cells expressing KITE-585, a chimeric antigen receptor targeting B-cell maturation antigen (BCMA)," the selectivity of KITE-585's novel single-chain variable fragment (scFv) for BCMA was assessed using Retrogenix™ cell microarray technology. The results demonstrated the specificity of KITE-585 for BCMA expressing target cells.
"These promising preclinical data presented at AACR suggest the potential of KITE-585 to offer a one-time treatment to address the high unmet need in multiple myeloma, an incurable blood cancer," said
About Multiple Myeloma
Multiple myeloma (MM) is a rare and aggressive cancer. In 2016, there were an estimated 30,330 new cases of MM and 12,650 disease-related deaths in the
KITE-585 is an investigational therapy in which a patient's T cells are engineered to express a chimeric antigen receptor (CAR) to target the B cell maturation antigen (BCMA), a protein expressed on the cell surface of multiple myelomas (MM), and redirect the T cells to kill cancer cells. Kite expects to file an investigational new drug application (IND) for KITE-585 and initiate a Phase 1 clinical trial of KITE-585 in 2017.
