BMS continues to advance its CTLA-4-directed Probody therapeutic, which is expected to enter the clinic in early 2018. . In addition, CytomX and Bristol-Myers Squibb are evaluating a Probody version of Bristol-Myers Squibb's CTLA-4 nonfucosylated (CLTA-4-NF) version of ipilimumab as part of the current collaboration.
