Brief Summary

This is a two-group, parallel, randomized, standard-control phase II study comparing the safety and efficacy of trifluridine/tipiracil combined with oxaliplatin and bevacizumab versus XELOX plus bevacizumab in the first-line treatment of advanced colorectal cancer. This study was conducted in the Department of Gastrointestinal Medical Oncology, Tianjin Medical University Cancer Institute and Hospital. Patients with advanced colorectal cancer will be randomly assigned (1:1) to trifluridine/tipiracil combined with oxaliplatin and bevacizumab (experimental group) or XELOX plus bevacizumab (control group) after signing informed consent. In this study, 184 patients will be enrolled, 92 patients will receive trifluridine/tipiracil combined with oxaliplatin and bevacizumab and 92 patients will receive standard therapy. In the experimental group, the treatment regimen is trifluridine/tipiracil 35mg/m2 orally taken on d1-5 and d8-12, oxaliplatin 85mg/m2 and bevacizumab 5mg/kg intravenously infused on d1 and d15 every 4 weeks, up to 6 cycles. Then patients will be given trifluridine/tipiracil and bevacizumab maintenance treatment. Patients enrolled in this group could acquire trifluridine/tipiracil free of charge. The control group was XELOX plus bevacizumab regimen, bevacizumab 7.5mg/kg, d1 oxaliplatin 130mg/m2, d1, capecitabine 1000mg/m2, orally, bid (half an hour after breakfast and dinner), d1-14, every 3 weeks, up to 8 cycles. Then patients will be given capecitabine and bevacizumab maintenance treatment. Patients received regular and periodic reviews, with imaging evaluations every 8 weeks. Safety will be evaluated by AE and laboratory tests. All patients were followed up every 3 months until death according to the plan.

EXPERIMENTAL

In the experimental group, the treatment regimen is trifluridine/tipiracil 35mg/m2 orally taken on d1-5 and d8-12, oxaliplatin 85mg/m2 and bevacizumab 5mg/kg intravenously infused on d1 and d15 every 4 weeks, up to 6 cycles. Then patients will be given trifluridine/tipiracil and bevacizumab maintenance treatment.

Drug: Trifluridine/Tipiracil

control group

NO INTERVENTION

The control group was XELOX plus bevacizumab regimen, bevacizumab 7.5mg/kg, d1 oxaliplatin 130mg/m2, d1, capecitabine 1000mg/m2, orally, bid (half an hour after breakfast and dinner), d1-14, every 3 weeks, up to 8 cycles. Then patients will be given capecitabine and bevacizumab maintenance treatment.

You may qualify if:

• Signed the informed consent.
• Age ≥18.
• Colonic adenocarcinoma confirmed histologically or histopathologically.
• No previous chemotherapy for advanced colorectal cancer, or patients who had received adjuvant chemotherapy after radical resection and relapsed 12 months after the completion of adjuvant chemotherapy.
• ECOG physical status score is 0 or 1.
• There are measurable metastatic lesions according to RECIST version 1.1.
• Appropriate organ function according to the following laboratory test values obtained within 7 days prior to use on Day 1 of Cycle 1:
• Hemoglobin value ≥9.0g/dL.
• Absolute neutrophil count ≥1,500/mm3 (≥1.5\*109/L).

• Total serum bilirubin ≤1.5\* upper normal limit (ULN).
• Aspartate aminotransferase (AST/SGOT) and alanine aminotransferase (ALT/SGPT) ≤2.5\* upper limit of normal value (ULN). If the abnormal liver function is due to liver metastasis, AST and ALT should be ≤5\*ULN.
• Serum creatinine ≤1.5 times \* upper limit of normal (ULN) or creatinine clearance ≥50ml/min.
• The results of urine or serum pregnancy test within 7 days prior to treatment were negative. Women who are likely to become pregnant and men must agree to take adequate contraceptive measures during the study period until 6 months after the end of medication.
• Survival is expected to be at least 3 months.

You may not qualify if:

• Has a serious illness or medical condition, including but not limited to the following:
• There are other active malignant tumors at the same time, excluding those that have not occurred for more than 5 years or carcinoma in situ that can be cured by adequate treatment.
• Known presence of brain metastases or leptomeningeal metastases.
• Systemic active infection (i.e., infection causes body temperature ≥38℃).
• Clinically significant intestinal obstruction, pulmonary fibrosis, renal failure, liver failure, or symptomatic cerebrovascular disease.
• Uncontrolled diabetes.
• Severe/unstable angina, New York Heart Association (NYHA) grade III or IV symptomatic congestive heart failure.
• Gastrointestinal bleeding of clinical significance.
• Known presence of human immunodeficiency virus (HIV) or acquired routine immunodeficiency syndrome (AIDS) -associated disease, or active hepatitis B or C.
• There are psychiatric disorders that may increase the risk associated with participating in the study or taking the study drugs, or may interfere with the interpretation of the study results.
• Any of the following treatments were received within a specific time frame before the study drug was taken:
• Major surgery in the previous 4 weeks. (Major surgery refers to laparotomy, thoracotomy, and laparoscopic resection of internal organs. On-off of abdomen was excluded)
• Radiotherapy with extended field within the previous 4 weeks or radiotherapy with limited field within the previous 2 weeks.
• Any investigational drugs within the previous 4 weeks.
• Presence of neurotoxicity of CTCAE grade 2 or above caused by adjuvant therapy.
