WALTHAM, Mass., July 31, 2025 (GLOBE NEWSWIRE) — 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 financial results for the second quarter ended June 30, 2025, and recent business highlights.

“The second quarter of 2025 was momentous for Crescent. We bolstered our leadership team, completed our merger and began trading on Nasdaq while also closing a substantial financing with a premier group of healthcare investors that will support the advancement of our portfolio of next generation therapeutics for solid tumors to important inflection points,” said Joshua Brumm, chief executive officer of Crescent. “Our lead program, CR-001, a PD-1 x VEGF bispecific antibody, is designed to transform the immuno-oncology standard of care, and we are on track to submit an IND by the end of 2025. This would enable dosing the first patients in our global Phase 1 trial in early 2026, with proof-of-concept data expected later that year. In addition, we expect the first of our two ADCs to enter the clinic in mid-2026. We have a tremendous opportunity ahead of us, and we remain focused on rapidly advancing our programs as we work toward delivering the next wave of treatments to those living with cancer.”
