Probody therapeutics are designed to exploit unique conditions of the tumor microenvironment to more effectively localize antibody binding and activity while limiting activity in healthy tissues. CytomX has four clinical-stage programs from a pipeline that includes cancer immunotherapies against clinically-validated targets, such as CX-072, a PD-L1-targeting Probody therapeutic wholly-owned by CytomX, BMS-986249, a CTLA-4-targeting Probody therapeutic partnered with Bristol-Myers Squibb and CX-188, a PD-1-targeting Probody therapeutic wholly-owned by CytomX.  CytomX is also developing first-in-class Probody drug conjugates against high potential targets, including CX-2009, a CD166-targeting Probody drug conjugate wholly-owned by CytomX, and CX-2029, a CD71-targeting Probody drug conjugate partnered with AbbVie, which are considered to be inaccessible to conventional antibody drug conjugates due to their presence on healthy tissue.
