Therapeutics developed with CytomX's Probody platform are designed to be active in the tumor while sparing healthy tissue. Due to their specific activity in the tumor microenvironment, Probody therapeutics directed against both validated and novel targets enable anti-tumor efficacy with a significantly enhanced safety window, relative to traditional antibody-based therapies. CytomX's preclinical pipeline of wholly-owned and partnered programs includes Probody cancer immunotherapies, Probody drug conjugates and T-cell engaging Probody bispecifics.

About CytomX Therapeutics
CytomX is an oncology-focused biopharmaceutical company pioneering a novel class of investigational antibody therapeutics based on its Probody technology platform. The company uses the platform to create development-stage proprietary cancer immunotherapies against clinically-validated targets, as well as to develop first-in-class investigational cancer therapeutics against novel targets. CytomX believes that its Probody platform has the potential to improve the combined efficacy and safety profile of monoclonal antibody modalities, including cancer immunotherapies, antibody drug conjugates and T-cell-recruiting bispecific antibodies. Probody therapeutics are designed to take advantage of unique conditions in the tumor microenvironment to enhance the tumor-targeting features of an antibody and reduce drug activity in healthy tissues. Investigational Probody therapeutics are being developed that address clinically-validated cancer targets in immuno-oncology, such as PD-L1 against which clinical candidate CX-072 is directed, as well as novel targets, such as CD-166, that are difficult to drug without causing damage to healthy tissues, or toxicities. In addition to its proprietary programs, CytomX is collaborating with strategic partners including Bristol-Myers Squibb Company, Pfizer Inc., The University of Texas MD Anderson Cancer Center and ImmunoGen, Inc.
