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. 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 uses its platform to create proprietary cancer immunotherapies against clinically-validated targets, such as PD-L1, and first-in-class cancer therapeutics against difficult-to-drug targets, such as CD166 and CD71. The Company’s lead program, CX-072, a wholly-owned PD-L1-targeting Probody therapeutic, is being evaluated in a Phase 1/2 study as 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. A Phase 1/2 clinical trial for CX-2009, a first-in-class Probody drug conjugate, targeting the highly expressed tumor antigen, CD166, is also in progress under the PROCLAIM umbrella. In addition to its wholly owned programs, CytomX is collaborating with strategic partners, including AbbVie, Bristol-Myers Squibb Company, Pfizer Inc., MD Anderson Cancer Center and ImmunoGen, Inc. BMS expects to advance its first collaboration product candidate, a Probody therapeutic targeting CTLA-4, into clinical studies in early 2018. CytomX, in collaboration with AbbVie, expects to advance the CD71-targeting Probody Drug Conjugate, CX-2029, into clinical studies in 2018.
