Researchers from Cytovia Therapeutics Inc. have presented preclinical data for the novel natural killer (NK) cell engager antibody CYT-338, which was designed using the proprietary FLEX-NKTM platform. CYT-338 contains a novel FLEX-linker to redirect NK cells expressing NKp46 activation receptor to kill CD38-expressing tumors, including multiple myeloma (MM). It was observed that the addition of CYT-338 led to dose-dependent enhancement iNK and PBNK cytolysis of the MM tumor spheroids.
