About CERo Therapeutics Holdings, Inc.
CERo is an innovative immunotherapy company advancing the development of next generation engineered T cell therapeutics for the treatment of cancer. Its proprietary approach to T cell engineering integrates key functional attributes of both innate and adaptive immunity within a single therapeutic construct, designed to engage the body’s immune repertoire for more comprehensive tumor targeting. This novel cellular immunotherapy platform is designed to redirect patient-derived T cells toward tumor cells through both adaptive perforin/granzyme pathways and innate engulfment mechanisms. The latter employ phagocytic activity to destroy cancer cells, creating what CERo refers to as Chimeric Engulfment Receptor T cells (“CER-T”). CERo believes the differentiated targeting properties of CER-T cells may offer advantages compared with currently approved CAR-T therapies and could potentially extend the reach of cellular immunotherapy to both hematologic malignancies and solid tumors. CERo has initiated clinical trials for its lead product candidate, CER-1236, for hematologic malignancies.
