- Drug Capecitabine
- Drug Iparomlimab and Tuvonralimab Injection
What it is measuring
Tumor Complete Response (CR) Rate
This is the trial's main question — the one it is designed and sized to answer. Anything else it reports is a secondary finding, and secondary findings are far more likely to be chance.
Phase 2. Tests whether the treatment works well enough to be worth a larger trial. Usually too small to prove it changes survival.
How the researchers describe it
The goal of this clinical trial is to evaluate the efficacy and safety of conversion therapy using radiotherapy combined with systemic treatment (chemotherapy + immune checkpoint inhibitors) for patients with pMMR/MSS T4M0 stage colon cancer. The main questions it aims to answer are:
1. Can the combination of radiotherapy and systemic treatment improve the R0 resection rate and complete response (CR) rate compared to chemotherapy alone?
2. Does this combination therapy enhance the tumor immune microenvironment, leading to better long-term outcomes?Researchers will compare the experimental group receiving concurrent chemoradiotherapy (CCRT) followed by 4 cycles of CAPOX + Iparomlimab and Tuvonralimab Injection with the control group receiving 4 cycles of CAPOX alone to see if the combination therapy offers superior efficacy.
Participants will:
1. Undergo preoperative CCRT combined with one cycle of Iparomlimab and Tuvonralimab Injection, followed by 4 cycles of CAPOX + Iparomlimab and Tuvonralimab Injection in the experimental group.
2. Receive 4 cycles of CAPOX in the control group.
3. After the initial treatment regimen, surgical candidates will undergo surgery followed by an additional 4 cycles of CAPOX. Non-surgical candidates will continue with 4 more cycles of CAPOX, completing a total of 8 cycles. Efficacy will be re-evaluated after the completion of 8 cycles.Written by the trial’s sponsor, quoted from its ClinicalTrials.gov record.

Who the trial is looking for
Inclusion Criteria
1. Age ≥18 years, no restriction on gender.
2. ECOG performance status of 0-1.
3. Histopathologically confirmed diagnosis of colon adenocarcinoma (including mucinous adenocarcinoma), identified as pMMR/MSS type; the primary tumor site must be specified (left colon defined as from the splenic flexure to the rectosigmoid junction, right colon defined as from the cecum to the proximal splenic flexure).
4. Baseline imaging (enhanced CT/MRI) confirms clinical staging as cT4NanyM0 according to the AJCC 8th edition staging criteria.
5. Laboratory criteria prior to enrollment must meet the following ranges:
(1) Hematology: Absolute neutrophil count ≥ 1.5 × 10^9/L, platelets ≥ 100 × 10^9/L, hemoglobin ≥ 90 g/L.
(2) Liver and renal function: ALT/AST ≤ 2.5 × ULN, total bilirubin ≤ 1.5 × ULN, creatinine ≤ 1.5 × ULN or creatinine clearance rate ≥ 60 mL/min (Cockcroft-Gault formula).
(3) Coagulation function: INR ≤ 1.5, APTT ≤ 1.5 × ULN (for those not on anticoagulation therapy).
6.Women of childbearing potential and men must agree to use effective contraception during the study and for 6 months after the last treatment.
7.Willingness to sign a written informed consent form and commit to completing the entire treatment and follow-up plan.

Where it is running
Running at 1 site. Listed in: China.
Individual hospitals, and whether each is currently open, are listed on the registry record. Sites open and close throughout a trial.
Worth asking your oncology team
Being listed here is not a recommendation, and no one page can tell you whether a trial is right for you. These are the questions it raises.
- Is this trial open at a hospital I could realistically travel to?
- Given my stage, my previous treatment and my tumour's molecular profile, would I be eligible?
- What would I be giving up by joining — is the comparison arm the treatment I would otherwise be having?
- What is already known about the safety of what is being tested?
