About CytomX Therapeutics
CytomX is a clinical-stage, oncology-focused biopharmaceutical company pioneering a novel class of investigational antibody therapeutics based on its Probody technology platform. The company utilizes the platform to create proprietary cancer immunotherapies against clinically-validated targets, such as PD-L1, and first-in-class cancer therapeutics against novel targets, such as CD166, that are difficult to drug without causing damage to healthy tissues. 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.  The company’s lead program, CX-072, a wholly-owned PD-L1-targeting Probody therapeutic, is being evaluated in a Phase 1/2 study. The Investigational New Drug filing for CX-2009 is planned for the first half of 2017.  CX-2009 is a first-in-class Probody drug conjugate targeting the highly expressed tumor antigen, CD166.  CX-072 is part of PROCLAIM (Probody Clinical Assessment In Man), an international umbrella clinical trial program that provides clinical trial sites with access to the company’s novel therapies under one central protocol.  In addition to its proprietary programs, CytomX is collaborating with strategic partners including AbbVie, Bristol-Myers Squibb Company, Pfizer Inc., MD Anderson Cancer Center and ImmunoGen, Inc.
