CytomX Therapeutics
CytomX Therapeutics is a clinical-stage, oncology-focused biopharmaceutical company in South San Francisco that engineers conditionally activated antibody therapeutics through its proprietary PROBODY platform. By masking a drug's binding site and unmasking it only in the tumor microenvironment - where specific proteases cut a cleavable linker - CytomX aims to hit cancer targets that are otherwise too toxic to drug, widening the therapeutic window for antibody-drug conjugates, T-cell engagers and cytokines. Its wholly owned pipeline is led by CX-2051, an EpCAM-targeting PROBODY ADC for metastatic colorectal cancer, alongside masked interferon CX-801 and T-cell engager CX-904, and it partners its technology with Amgen, Astellas, Bristol Myers Squibb, Moderna and Regeneron.
