New cocktail attack on stubborn colon cancer
NCT ID NCT07622550
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase 2 trial is testing a combination of two targeted drugs (fruquintinib and serplulimab) plus chemotherapy as a first treatment for 80 people with advanced colorectal cancer that has RAS or BRAF mutations. The goal is to see if this mix can delay cancer growth and improve survival. Participants will receive the drugs in cycles, followed by maintenance therapy if their disease is controlled.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- fruquintinib, serplulimab, and chemotherapy (oxaliplatin and capecitabine)
- What this could lead to
- If successful, this could offer a new first-line treatment option for people with a hard-to-treat form of advanced colorectal cancer.
- What could go wrong
- This is a small, early-phase (phase 2) trial with no control group, so results may not be definitive. The drug combination may cause significant side effects.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * 18 to 75 years (inclusive), male or female. * Diagnosis of advanced unresectable or metastatic colorectal cancer. * Confirmed RAS/BRAF mutation by testing. * No prior systemic therapy for unresectable or metastatic colorectal cancer. (Prior adjuvant or neoadjuvant chemotherapy with one regimen is allowed if recurrence occurred ≥6 months after completion of chemotherapy.) * ECOG 0 - 1. * Adequate major organ and bone marrow function (without any blood component or cell growth factor support within 14 days before enrollment): 1. Hematology: absolute neutrophil count ≥1.5 × 10⁹/L, platelet count ≥100 × 10⁹/L, hemoglobin ≥90 g/L. 2. International normalized ratio (INR) ≤1.5 × upper limit of normal (ULN), and activated partial thromboplastin time (APTT) ≤1.5 × ULN. 3. Liver function: total bilirubin ≤1.5 × ULN; ALT/AST ≤2.5 × ULN (≤5 × ULN in patients with liver metastases). 4. Renal function: serum creatinine ≤1.5 × ULN, and creatinine clearance (CCr) ≥50 mL/min. * Female patients of childbearing potential must have a negative serum pregnancy test within 14 days before treatment. Fertile patients (male and female) must agree to use reliable contraceptive methods (hormonal, barrier, or abstinence) with their partners during the study and for at least 6 months after the last dose Exclusion Criteria: * \- History of hypersensitivity to any anti-angiogenic targeted agent, any component of monoclonal antibodies, capecitabine, oxaliplatin, or other platinum-based drugs. * Untreated central nervous system (CNS) metastases. * Major surgery or severe trauma within 4 weeks prior to first study drug administration. * Current use of immunosuppressive agents, or systemic or absorbable local hormone therapy for immunosuppressive purposes (dose \>10 mg/day prednisone or equivalent), and continued use within 2 weeks before enrollment. * Presence of any active autoimmune disease or history of autoimmune disease. * History of other malignancies within the past 5 years, except for radically resected basal cell or squamous cell carcinoma of the skin, or carcinoma in situ of the cervix. * Known inherited or acquired bleeding/thrombotic tendency (e.g., hemophilia, coagulation dysfunction, thrombocytopenia, hypersplenism, etc.) or currently receiving thrombolytic or anticoagulant therapy. * Currently active bleeding or significant bleeding tendency within 3 months (i.e., patients at high risk of bleeding).
