A Randomized, Active-Controlled, Double-blind, Multicenter, Phase 3 Clinical Study of Ivonescimab in Combination with FOLFOX versus Bevacizumab in Combination with FOLFOX for the First-line Treatment of Metastatic Colorectal Cancer (HARMONi-GI3)
EU CTIS ID: 2025-521587-35-00
What this study is testing
To compare the progression-free survival (PFS) as assessed by blinded Independent Radiological Review Committee (IRRC) based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, of ivonescimab in combination with modified 5 FU, oxaliplatin, and leucovorin (mFOLFOX6) to bevacizumab in combination with mFOLFOX6.
- Therapeutic confirmatory (Phase III)

Who can take part
You may be able to join if
- Histologically or cytologically confirmed mCRC, not amenable to curative resection.
- An Eastern Cooperative Oncology Organization Group (ECOG) performance status score of 0 or 1.
- No prior systemic therapy for mCRC. NOTE:- If patients have received systemic therapy or radiotherapy for early-stage disease, >12 months must have elapsed since completion of neoadjuvant therapy and/or adjuvant therapy (including adjuvant oxaliplatin or radiotherapy) and prior to diagnosis of recurrent or metastatic disease.
- At least one measurable tumor lesion according to RECIST v1.1 that is amenable to repeated accurate measurements. NOTE:- Brain metastases cannot be selected as target lesions and lesions that have received radiotherapy in the past cannot be selected as target lesions unless they have progressed following radiation
- Known BRAF, KRAS and NRAS (extended RAS) mutation status from existing reports, or determined by testing tumor tissue utilizing a clinical assay.
You likely can't join if
- Patients with known MSI-H/dMMR disease as determined by a health authority approved assay (eg, FDA for United States, CE-IVD marked for Europe, PMDA for Japan, and NMPA for China) conducted at a local clinical laboratory or at the central laboratory.
- Known BRAF V600E mutation status. known DPD deficiency (refer to local fluorouracil label or local clinical guidance for DPD status recommendation prior to starting treatment).
- Patients who have received prior immunotherapy or anti-angiogenic therapy for colorectal cancer, including immune checkpoint inhibitors, immune checkpoint agonists, immune cell therapy and any other therapy based on the mechanism of action of tumor immunity or angiogenesis
- Symptomatic central nervous system (CNS) metastases with hemorrhagic features, CNS metastasis ≥ 1.5 cm, CNS radiation within 7 days prior to randomization, potential need for CNS radiation within the first cycle, or leptomeningeal disease. NOTE:- Patients who have stopped corticosteroids or on stable corticosteroid therapy (prednisone ≤ 10 mg daily or equivalent) are allowed.
- Resectable oligometastastic-only disease with multidisciplinary plan for complete resection of all disease.
- Ascites requiring paracentesis within last 30 days.
