New hope for advanced colon cancer: drug cocktail trial launches

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

ECOG PS score ≤2; * 5\. Expected survival ≥3 months; * 6\. MSS/MSI-L status; * 7\. At least one evaluable lesion based on RECIST 1.1 criteria; * 8\. No prior systemic chemotherapy or other systemic therapy, or only received adjuvant chemotherapy with disease progression or recurrence within 6 months after completion of treatment; * 9\. Adequate organ function reserve, with specific hepatic, renal, and hematologic parameters as follows: 1. White blood cell count ≥3.5×10⁹/L 2. Absolute neutrophil count ≥1.5×10⁹/L 3. Hemoglobin ≥100 g/L 4. Platelets ≥80×10⁹/L 5. Serum liver enzymes ≤2.5× upper limit of normal (ULN) in patients without liver metastases 6.

Presence of non-measurable lesions (e.g., pleural effusion/ascites, carcinomatous lymphangitis, diffuse liver involvement, bone metastases); * 4\. Pregnant or lactating women; * 5\. Uncontrolled symptomatic brain metastases or psychiatric disorders preventing accurate expression of subjective symptoms; * 6\. Vital organ function failure; * 7\. Conditions affecting drug absorption/distribution/metabolism/excretion (e.g., seizures, central nervous system diseases, cognitive impairment due to psychiatric disorders, chronic diarrhea, cachexia, etc.); * 8\. Patients with complete or incomplete intestinal obstruction; * 9\. History of severe cardiac disease (including congestive heart failure, uncontrolled high-risk arrhythmia, angina requiring medication, definite valvular heart disease history, severe myocardial infarction, refractory hypertension); * 10\.
