Bristol-Myers Squibb Advances CytomX Therapeutics’ Anti-CTLA-4 Probody Therapeutic BMS-986249 into Randomized Cohort Expansion (Part 2a) of Ongoing Clinical Trial
Expansion Phase to Evaluate CTLA-4-Directed Probody® Therapeutic in Combination with Opdivo® in Metastatic Melanoma
Bristol-Myers Squibb also Advances BMS-986288 into a Separate Phase 1/2a Clinical Trial
These Probody programs, designed to optimize the risk-benefit profile of CTLA-4-directed therapy, arose from the companies’ foundational 2014 worldwide oncology license and collaboration agreement.
“CTLA-4 is the prototypical checkpoint target and blocking this mechanism has proven highly effective in the treatment of melanoma and other cancer types. This exciting progress within our alliance with Bristol-Myers Squibb is aimed at the development of anti-CTLA-4 therapies to broaden the reach of this foundational pathway for cancer patients,” said
CytomX is a clinical-stage, oncology-focused biopharmaceutical company with a vision of transforming lives with safer, more effective therapies. We are developing a novel class of investigational antibody therapeutics, based on our Probody® technology platform, for the treatment of cancer. As leaders in the field, our innovative technology is designed to turn previously undruggable targets into druggable targets and to enable more effective combination therapies. CytomX and its partners, comprised of leading biotechnology and pharmaceutical companies, have developed a robust pipeline of potential best-in-class immunotherapies against clinically validated targets and potential first-in-class therapeutics against novel, difficult to drug targets. Five novel drug-candidates utilizing our Probody technology are in clinical trials, with three in Phase 2 studies and two in Phase 1. These clinical programs include cancer immunotherapies against validated targets such as a PD-L1-targeting Probody therapeutic wholly owned by CytomX (CX-072) and a CTLA-4-targeting Probody therapeutic partnered with Bristol Myers Squibb (BMS-986249). The CytomX clinical stage pipeline also includes first-in-class Probody drug conjugates against previously undruggable targets, including a CD166-targeting Probody drug conjugate wholly owned by CytomX (CX-2009) and a CD71-targeting Probody drug conjugate partnered with AbbVie (CX-2029). CD166 and CD71 are among cancer targets considered to be inaccessible to conventional antibody drug conjugates due to their presence on many healthy tissues. In addition to its wholly owned programs, CytomX has strategic collaborations with AbbVie, Amgen and BMS. For additional information about
