Crescent Biopharma, Inc. ("Crescent" or the "Company") (Nasdaq: CBIO), a biotechnology company dedicated to rapidly advancing the next wave of therapies for cancer patients, today announced that preclinical data from CR-001, its PD-1 x VEGF bispecific antibody being developed for solid tumors, will be presented at the Society for Immunotherapy of Cancer's (SITC) 40th Annual Meeting being held November 7-9, 2025 in National Harbor, Maryland.

CR-001 is a tetravalent bispecific antibody combining two complementary, validated mechanisms in oncology via a blockade of PD-1 and VEGF. In data to be presented at SITC, CR-001 demonstrated cooperative pharmacology in vitro with increased binding to PD-1 in the presence of VEGF, augmenting the PD-1/PD-L1 signaling blockade and enhancing T-cell activation. This cooperativity was consistent with preclinical evaluation of ivonescimab, another tetravalent PD-1 x VEGF bispecific antibody, which demonstrated superior efficacy compared to the current market leader, pembrolizumab, in a large, third-party Phase 3 trial in non-small cell lung cancer.1,2 CR-001 also showed potent anti-tumor activity in a xenograft mouse model, and was well-tolerated in non-human primates after a single intravenous dose with robust PD-1 receptor occupancy.
