Enrollment is ongoing in ASCEND (<a href="https://www.globenewswire.com/Tracker?data=iWUn9qzQttvoWlu7Q_6IFlejDbllbfwUqxuotzGtLCMkqfYLRHtv60sHNnWRIdVY7N1YXpVwQvLMJaUBwjXZKIHCofwjU8P5dFrmreQm0BMunmTyce0Vp8dggk_uqRB3" rel="nofollow" target="_blank">NCT07335497</a>), a global, open-label Phase 1/2 clinical trial evaluating CR-001 in multiple solid tumor types, including non-small cell lung cancer (NSCLC) and various gastrointestinal and gynecological cancers, in both treatment-naïve and previously treated patients. The trial is expected to enroll up to 290 patients in dose-escalation, backfill and dose-optimization cohorts at centers across multiple regions, including the United States, Europe and Asia Pacific. The primary objectives of the study are to evaluate the safety and tolerability of CR-001. Secondary objectives include the assessment of pharmacokinetic and pharmacodynamic profiles, identification of the recommended Phase 2 dose, and evaluation of preliminary antitumor activity, including overall response rate (ORR), duration of response (DoR), progression-free survival (PFS), and overall survival (OS). "CR-001 is designed to serve as an immuno-oncology backbone and best-in-class PD-1 x VEGF bispecific antibody for people living with cancer," said Ellie Im, M.D., chief medical officer of Crescent. "We are encouraged by the strong global engagement from investigators involved in ASCEND, which underscores both the unmet need in cancer treatment and the study's efficient design to evaluate CR-001 as a monotherapy and in combination with standard-of-care therapies. Together with our planned ADC combination studies, this development strategy is intended to rapidly expand our understanding of CR-001 across multiple solid tumor types, beginning with initial ASCEND data expected in the first quarter of 2027." Crescent anticipates reporting: <ul type="disc"><li>Proof-of-concept clinical data from the ASCEND trial of CR-001 in the first quarter of 2027, including initial safety, pharmacokinetics, pharmacodynamics and preliminary antitumor activity from dose escalation and backfill cohorts in first-line and previously treated patients in multiple solid tumor types.

About CR-001 CR-001 is an investigational tetravalent bispecific antibody being developed for the treatment of solid tumors that combines two complementary, validated mechanisms in oncology via a blockade of PD-1 and VEGF. PD-1 checkpoint inhibition is aimed at restoring T cells' ability to recognize and destroy tumor cells, and blocking VEGF is intended to reduce blood supply to tumor cells and to inhibit tumor growth. In preclinical studies, CR-001 demonstrated cooperative pharmacology with increased binding to PD-1 and signal blockade in the presence of VEGF as well as robust antitumor activity. CR-001 is currently being evaluated in ASCEND (<a href="https://www.globenewswire.com/Tracker?data=iWUn9qzQttvoWlu7Q_6IFllum9fJyL7YgLdPofD1-flQL_e4CTp3Hxzz13yc1vL6wTdhjmZX5PMknRI5N8DdMQPEjCamP85lPScI79OhTQrEvRqAO4fg-x1qnMcayBeK" rel="nofollow" target="_blank">NCT07335497</a>), a global Phase 1/2 trial in patients with advanced solid tumors. CR-001's anti-VEGF activity may also normalize the vasculature at the tumor site, which has the potential to improve the localization and effectiveness of combination therapies, such as the administration of CR-001 with Crescent's antibody-drug conjugates (ADCs) in development. The first Phase 1/2 ADC combination trial with CR-001 is expected to initiate in the second half of 2026. Under its strategic collaboration, Crescent has granted Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd., exclusive rights to research, develop, and commercialize CR-001 (also known as SKB118) in Greater China (including mainland China, Hong Kong, Macau and Taiwan). Kelun-Biotech plans to initiate a Phase 1/2 trial of CR-001 (SKB118) in China in the first half of 2026. CR-001 was discovered by Paragon Therapeutics, an antibody discovery engine founded by Fairmount. About Crescent Biopharma Crescent Biopharma's vision is to build a world leading oncology company bringing the next wave of therapies for cancer patients. The Company's clinical-stage pipeline includes its lead program, a PD-1 x VEGF bispecific antibody, as well as novel antibody-drug conjugates (ADCs). By leveraging multiple modalities and established targets, Crescent aims to rapidly advance potentially transformative therapies either as single agents or as part of combination regimens to treat a range of solid tumors.
