Crossbow Therapeutics Inc. has nominated its first development candidate, CBX-250, a first-in-class, potent and specific T-cell engager (TCE) for the treatment of myeloid leukemia. CBX-250 targets a cathepsin G (CTSG) peptide-human leukocyte antigen (pHLA) complex abundantly expressed on leukemic cells, but not on normal cells.
T-cell-engaging antibodies (TCEs) are synthetic molecules that redirect T cells to bind to the antigens on the surface of cancer cells to promote tumor elimination. In the case of multiple myeloma (MM), the approvals of anti-CD38 monoclonal antibodies (MAbs), chimeric antigen receptor T-cell therapies (CAR T) targeting B-cell maturation antigen (BCMA) or, more recently, bispecific TCEs represent great advances, but some patients still relapse after treatment.
Strong early data of Janux Therapeutics Inc.’s tumor-activated T-cell engager compounds JANX-007 and JANX-008 sent the San Diego-based company’s shares surging by 229%, indicating enthusiasm for their best-in-class potential and the possibility of tapping into multibillion-dollar prostate cancer and solid tumor markets.
CDR-Life Inc. has announced FDA clearance of an IND application for CDR-404, its lead program in development as a precision immunotherapy for solid tumors.
Biocytogen Pharmaceuticals Co. Ltd. and Ctm Biotech Co. Ltd. have reported progress in the development of a trispecific T-cell engager for an intracellular target.
Five months after the first anti-CD20xCD3 T-cell engaging bispecific antibody, Roche Holding AG’s Lunsumio (mosunetuzumab), cleared U.S. FDA approval for follicular lymphoma, partners Genmab A/S and Abbvie Inc. won the agency’s approval for epcoritamab as the first subcutaneous CD20xCD3 bispecific antibody for treating diffuse large B-cell lymphoma.
