Evaluate the Efficacy of Irinotecan Versus Oxaliplatin in the First-line Treatment of Refractory Metastatic Colorectal Cancer

Phase 2

• Conditions: mCRC
• Interventions: Drug: Irinotecan; Drug: Oxaliplatin

• Registration Number: NCT03567629
• Lead Sponsor: Peking University

Brief Summary

This is a prospective, open-lable, multicenter, randomized, controlled, phase II clinical study. The aim is to evaluate the efficacy of Irinotecan versus Oxaliplatin in the first-line treatment of refractory metastatic colorectal cancer.

Detailed Description

This trial is conducted in patients with the refractory metastatic colorectal cancer. Eligible patients are randomized into two arms at 1:1 ratio to receive Irinotecan-based regimen or Oxaliplatin-based regimen until progress of the disease, unacceptable toxicity or withdrawal of consent by the patient. Study evaluation time is until death of patient or a deadline set by the researchers.

2. Metastatic lesion is subject to be treated by local intervention.
3. Subjects with BRAF V600E mutation.
4. Presence of other active malignancies or a history of other malignancies within the past 5 years, except for carcinoma in situ of the cervix, basal cell carcinoma of the skin that has been previously treated with curative intent.
5. Subjects with cerebral metastasis, spinal cord compression, carcinomatous meningitis, CT /MRI examination reveals diseases of the brain or pia mater during screening.
6. Subjects with chronic diarrhea, intestinal obstruction or incomplete intestinal obstruction, or severe peripheral nerve disease.
7. Any of the following diseases occurred in the 12 months before the study: Myocardial infarction, severe / unstable angina pectoris, coronary artery / peripheral artery bypass grafting, symptomatic congestive heart failure, cerebrovascular accident, or transient ischemic attack, or pulmonary embolism within 6 months
8. Subject is known to be infected with Immunodeficiency virus (HIV) or associated with acquired immune deficiency syndrome (AIDS).
