CytomX Therapeutics, Inc. announced that Bristol-Myers Squibb Company has selected a clinical candidate for its CTLA-4 Probody program under the strategic oncology collaboration established in May 2014. Achieving this milestone results in a $2 million payment to CytomX.
“Selecting a candidate for the CTLA-4 Probody program is a pivotal development in our partnership with CytomX Therapeutics and builds on our I.O. leadership,” said Carl Decicco, Ph. D., Head of Discovery at Bristol-Myers Squibb. “We are studying the CTLA-4 Probody for its potential to deliver a next-generation anti-CTLA-4 therapy as we continue to explore transformational immuno-oncology medicines.”
CTLA-4, a clinically validated inhibitory immune checkpoint protein, is the most advanced target from the companies’ collaboration, which now also includes three additional, unnamed targets in discovery.
“Advancing our CTLA-4 Probody program to clinical candidate stage with Bristol-Myers Squibb underscores the potential of the Probody platform to transform the field of immuno-oncology by delivering safer, more effective therapies,” said Sean McCarthy, D.Phil., President and Chief Executive Officer of CytomX. “This partnership milestone, taken together with CytomX’s recently filed Investigational New Drug application for CX-072, a wholly owned PD-L1-directed Probody therapeutic, highlights the potential of our innovative platform to deliver a new generation of anti-cancer treatments.”
