What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

In Phase 2, researchers evaluate early signs of effectiveness. You may be randomized to receive the active treatment or a comparator. Monitoring continues closely.

This trial targets 30 participants in total. It began in 2024-09-01 with a primary completion date of 2026-07-31.

Brief Summary

Phase II clinical study of irinotecan liposome (II)-based combination regimen as a treatment for irinotecan-resistant colorectal cancer.

Laboratory tests were to meet the following requirements: hemoglobin (Hb) ≥ 9 g/dL (90 g/L) (no corrective treatment used within 14 days); neutrophil count (ANC) ≥ 1,500/mm3 (1.5 × 109/L) (no growth factors used within 14 days); white blood cell count (WBC) ≥ 3.0 × 109/L(no corrective treatment used within 14 days);platelet count (PLT) ≥ 100,000/mm3 (100 × 109/L) (no corrective treatment used within 14 days) ; total bilirubin (TBIL) ≤ 1.5 times the upper limit of normal (ULN); Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels ≤ 3 times the upper limit of normal (ULN), and ≤ 5 × ULN for patients with liver metastases; Serum Cr ≤ 1.5 times ULN, endogenous creatinine clearance \> 50ml/min (Cockcroft-Gault formula);Doppler ultrasound evaluation: Left ventricular ejection fraction (LVEF) ≥ lower limit of normal (50%); international normalized ratio INR ≤ 1.5 × ULN and activated partial thromboplastin time ≤ 1.5 × ULN; * Patients with potential fertility need to use a medically recognized contraceptive (such as intrauterine device, contraceptives or condoms) during study treatment and within 6 months after the end of study treatment; and must have a negative serum HCG test within 7 days before study enrollment; and must be non-lactating. Male participants in this study consent to the utilisation of contraceptive measures for the duration of the study period, in addition to a six-month period subsequent to the study's conclusion. Exclusion Criteria: * Previously or simultaneously suffering from other malignant tumors, except for cured skin basal cell carcinoma and cervical carcinoma in situ; * Participated in clinical trials of other drugs within the four weeks prior to enrollment; * Severe gastrointestinal dysfunction (bleeding, obstruction; inflammation greater than grade 2; diarrhea greater than grade 1); * Patients with gastrointestinal perforation, gastrointestinal fistula, intra-abdominal abscess, and non gastrointestinal fistula (such as tracheoesophageal fistula) within the first 6 months of enrollment； * Patients with clinical symptoms of ascites requiring puncture and drainage (excluding those with only a small amount of ascites on imaging and controllable, but without clinical symptoms); * The third fluid accumulation (such as a large amount of pleural effusion) cannot reach a stable state within 2 weeks before enrollment after treatment (no intervention treatment is required after removing the drainage tube); * Patients with a clear tendency towards gastrointestinal bleeding, including the following conditions: local active ulcer lesions and fecal occult blood \[(++) not eligible for inclusion\]; Individuals with a history of black stool and vomiting blood within 2 months; * Known interstitial lung disease, except for interstitial changes shown only by imaging; * Patients known to have central nervous system metastases or a history of central nervous system metastases prior to screening. For patients suspected of having central nervous system metastasis in clinical practice, enhanced CT or enhanced magnetic resonance imaging (MRI) examination must be performed within 28 days before enrollment to rule out central nervous system metastasis; * Within 2 weeks prior to enrollment, concomitant medications containing strong inhibitors/inducers of CYP3A4, CYP2C8, or UGT1A1; * Individuals with hypertension who cannot achieve good control with single antihypertensive medication (systolic blood pressure\>140 mmHg, diastolic blood pressure\>90 mmHg); Individuals with a history of unstable angina pectoris; Newly diagnosed with angina pectoris within the first 3 months of screening or experiencing myocardial infarction events within the first 6 months of screening; Cardiac arrhythmia (including QTcF: male ≥ 450 ms, female ≥ 470 ms) requires long-term use of antiarrhythmic drugs and New York Heart Association classification of ≥ II heart failure; * Individuals who are known to be allergic to any of the ingredients in Irinotecan Liposomes (II), other liposome products, Bevacizumab or Cetuximab, etc; * Individuals with abnormal coagulation function and bleeding tendency (must meet the requirement of INR being within the normal range without using anticoagulants within 14 days before enrollment); Patients treated with anticoagulants or vitamin K antagonists such as warfarin, heparin, or their analogues; Under the condition that the International Normalized Ratio (INR) of prothrombin time is ≤ 1.5, it is allowed to use low-dose warfarin (1 mg orally, once daily) or low-dose aspirin (daily dose not exceeding 100 mg) for preventive purposes; * For female participants: Non surgical sterilization or non postmenopausal patients who refuse to use a medically approved contraceptive measure during the study treatment period and within 6 months after the end of the study treatment period; Women of childbearing age who tested positive for pregnancy in serum or urine within 7 days prior to enrollment in the study, or are currently breastfeeding.
