Company: CytomX Therapeutics (USA - CA)
Product: CX-2009
Action
mechanism:
- probody/antibody drug conjugate. CX-2009 is a probody drug conjugate (PDC) that targets cell surface protein CD-166. CD-166 is highly and homogeneously expressed on multiple tumor types, such as breast cancer, endometrial cancer and prostate cancer. CytomX has demonstrated that CD-166 effectively internalizes antibody-drug conjugates resulting in potent cell killing in-vitro. CX-2009 is designed to target CD-166 specifically in the tumor microenvironment and deliver the tubulin-destabilizing maytansine payload, DM4, to cancer cells.
- In 2014, CytomX entered into a license agreement with ImmunoGen, Inc. to develop PDCs against a defined number of targets, bringing together CytomX's proprietary antibody masking technology and tumor-selective protease substrates with ImmunoGen's highly potent antibody drug conjugate cell-killing agents and engineered linkers. CX-2009 is wholly owned by CytomX.
