bispecific antibody medical
"CR-001, a PD-1 x VEGF bispecific antibody, in multiple solid tumor types"
A bispecific antibody is a specially designed protein that can attach to two different targets at the same time. Think of it as a custom-made connector that brings two things together—such as a disease cell and an immune system component—helping the body fight illnesses more effectively. For investors, understanding bispecific antibodies is important because they represent innovative therapies that could lead to new treatments and potentially lucrative market opportunities.
antibody-drug conjugates (ADCs) medical
"novel antibody-drug conjugates (ADCs). By leveraging multiple modalities"
Antibody-drug conjugates (ADCs) are advanced medicines that combine a targeted antibody with a powerful drug, acting like a guided missile to deliver treatment directly to cancer cells while sparing healthy tissue. This precision approach can improve effectiveness and reduce side effects, making ADCs a promising area of biotech innovation. For investors, advancements in ADC technology can signal potential growth opportunities in the pharmaceutical and healthcare sectors.
Phase 1/2 clinical trial medical
"ASCEND, a global, open-label Phase 1/2 clinical trial evaluating CR-001"
A phase 1/2 clinical trial is an early human study that combines first-in-people safety and dosing checks (phase 1) with an initial look at whether the treatment appears to work (phase 2). Think of it as a short test drive where researchers both confirm the product won’t cause serious harm and gather early signs it could be effective; for investors, successful results reduce risk and can unlock value-creating milestones like larger trials or regulatory discussions.
Investigational New Drug (IND) application regulatory
"on track to submit an Investigational New Drug (IND) application to the FDA"
An investigational new drug (IND) application is a formal request submitted to a drug regulator asking permission to begin testing a new medicine in people. It compiles lab results, manufacturing details and proposed human trial plans so regulators can judge safety before human studies start; for investors, an accepted IND is a key milestone that opens the clinical development pathway and can materially change a company’s risk profile and potential value, like getting a license to road-test a prototype.
proof-of-concept data medical
"proof-of-concept clinical data from the ASCEND trial of CR-001 in the first quarter of 2027"

Multiple key clinical data readouts anticipated beginning in Q1 2027

Waltham, Mass., April 29, 2026 – Crescent Biopharma, Inc. (“Crescent” or the “Company”) (Nasdaq: CBIO), a clinical-stage biotechnology company dedicated to rapidly advancing the next wave of therapies for cancer patients, today announced financial results for the first quarter ended March 31, 2026 and recent business highlights.
“Crescent’s execution on the advancement of our pipeline this quarter positions us for meaningful clinical data readouts in 2027 from CR-001, our potentially best-in-class PD-1 x VEGF bispecific antibody, as well as our differentiated ADC programs. The innovative design of our Phase 1/2 ASCEND study of CR-001 enables us to quickly generate comprehensive data for this next generation immuno-oncology backbone both as monotherapy and in combination with standard of care chemotherapy in multiple tumor types, and we’re also working with our partner, Kelun-Biotech, to deliver ADC combination data,” said Joshua Brumm, chief executive officer of Crescent. “We are pleased that both our global ASCEND trial and the Phase 1/2 trial of CR-003 in China are progressing well. We are on track to initiate two more trials during the second half of 2026, with the first ADC combination study for CR-001 and planned clinic entry for CR-002. This continued momentum underscores our commitment to delivering transformative therapies for people living with cancer.”
Recent Business Highlights & Anticipated Milestones
CR-001, PD-1 x VEGF bispecific antibody
CR-001 is an investigational tetravalent bispecific antibody that combines two complementary, validated mechanisms in oncology via a blockade of PD-1 and VEGF. Enrollment is ongoing in ASCEND, 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.
A trial in progress abstract of the ASCEND study design has been accepted for poster presentation during the 2026 American Society of Clinical Oncology (ASCO) Annual Meeting being held May 29-June 2, 2026 in Chicago: “ASCEND: A phase 1/2, dose-escalation, optimization, and dose-expansion study to evaluate the safety and antitumor activity of CR-001 in adults with locally advanced or metastatic solid tumors.”

Under its strategic collaboration, Crescent granted Sichuan Kelun-Biotech Biopharmaceutical Co., Ltd., (“Kelun-Biotech”) exclusive rights to research, develop, and commercialize CR-001 (also known as SKB118) in Greater China. Kelun-Biotech plans to initiate a Phase 1/2 trial of CR-001 (SKB118) in China in the first half of 2026.

Crescent also plans to evaluate CR-001 in combination with multiple ADCs, including CR-002 and CR-003. Initiation of the first Phase 1/2 combination trial of CR-001 with a Kelun-Biotech ADC is expected in the second half of 2026 in China.
Crescent anticipates reporting:
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. A backfill cohort of first-line NSCLC patients is planned as part of this readout.
Initial data of CR-001 in combination with standard of care chemotherapy in first-line and previously treated patients by mid-2027 (Q2/Q3) utilizing the dose expansion part of the ASCEND trial.
Initial data from the Phase 1/2 trial in China of CR-001 in combination with a Kelun-Biotech ADC in mid-2027 (Q2/Q3).
CR-002, topoisomerase inhibitor ADC targeting PD-L1
CR-002 is a topoisomerase inhibitor ADC directed to PD-L1, a validated target known to have high expression in multiple solid tumors. CR-002 incorporates a PD-L1 antibody selected for high internalization to facilitate payload release in target cells and a linker designed for intracellular cleavage and high stability in circulation.
Crescent is on track to submit an Investigational New Drug (IND) application to the FDA for CR-002 in mid-2026 to support the initiation of a Phase 1/2 trial in solid tumors in the second half of 2026, with proof-of-concept data expected in the second half of 2027.
CR-003, topoisomerase inhibitor ADC targeting integrin beta-6 (ITGB6)
CR-003 is an investigational topoisomerase inhibitor ADC directed to ITGB6, which is overexpressed in many solid tumors with minimal expression in most normal tissues. CR-003 consists of an anti-ITGB6 fully human IgG1 monoclonal antibody conjugated via a stable, clinically validated cleavable linker.
A Phase 1/2 trial of CR-003 (also known as SKB105) in participants with advanced solid tumors led by Kelun-Biotech in China is ongoing and proof-of-concept data are expected in the first quarter of 2027. A Phase 1/2 combination trial of CR-003 and CR-001 is expected to initiate in the first half of 2027, with initial data anticipated by year-end 2027. Under its strategic collaboration, Kelun-Biotech granted Crescent exclusive rights to research, develop, and commercialize CR-003 (SKB105) in the United States, Europe and all markets outside of Greater China.
