The company’s platform leverages tumor-activated peptides designed to bind to the fibrin–fibronectin complexes uniquely present in solid tumors, with the goal of improving the therapeutic index of cytotoxic payloads while limiting off-target effects. Its lead asset, MH1, is a peptide–drug conjugate in Phase I clinical trials for advanced solid tumors. MH1 is engineered to remain inert in circulation and to be activated by tumor-associated proteases, delivering potent chemotherapeutic agents directly to the tumor microenvironment. Mateon also maintains a preclinical pipeline exploring additional peptide constructs intended to address cancers with high unmet medical need, such as ovarian and colorectal indications. Headquartered in Redwood City, California, Mateon collaborates with academic research centers and contract development organizations to advance its candidates through IND-enabling studies and early-stage clinical work. The company’s leadership team combines experience in oncology drug development, peptide chemistry and clinical operations, positioning Mateon to progress its targeted therapies toward regulatory milestones and potential strategic partnerships.AI Generated.
