Summary

This is a prospective, multicenter, randomized controlled, phase II study. It is expected to enroll 229 patients and aims to evaluate the efficacy and safety of FOLFOX8 versus mFOLFOX6 combined with bevacizumab or cetuximab as first-line treatment for unresectable metastatic colorectal cancer. The primary objective is to assess progression-free survival (PFS) of the patients. Secondary objectives include assessment of objective response rate (ORR), overall survival (OS), safety, and other outcomes.

Conditions

  • Metastatic Colorectal Cancer (CRC)

Interventions

DRUG

Oxaliplatin

85 mg/m² intravenously over 2 hours on Day 1, every 2 weeks for up to 12 cycles. For patients without disease progression after 12 cycles, oxaliplatin is discontinued and not used in maintenance.

DRUG

5-Fluorouracil

400 mg/m² intravenous bolus on Day 1, followed by 2400 mg/m² administered as a continuous intravenous infusion over 46-48 hours. Cycle repeats every 2 weeks for up to 12 cycles. Patients without disease progression then enter maintenance with the same 5-FU regimen every 2 weeks until disease progression or unacceptable toxicity.

DRUG

Levofolinic Acid For Injection

200 mg/m² mixed with 5-FU 2400 mg/m² as a continuous intravenous infusion over 46-48 hours on Day 1 (concurrent infusion). Cycle repeats every 2 weeks for up to 12 cycles. Patients without disease progression then enter maintenance with the same mixture every 2 weeks until disease progression or unacceptable toxicity.

DRUG

Calcium Folinate

400 mg/m² intravenously over 2 hours on Day 1, administered sequentially before 5-FU. Cycle repeats every 2 weeks for up to 12 cycles. Patients without disease progression then enter maintenance with the same dose and schedule of calcium folinate (without oxaliplatin) every 2 weeks until disease progression or unacceptable toxicity.

DRUG

Bevacizumab

5 mg/kg intravenously on Day 1 every 2 weeks, starting from Cycle 2 (after genetic testing results are available). Continue through induction and maintenance until disease progression or unacceptable toxicity.

DRUG

Cetuximab (EGFR inhibitor)

500 mg/m² intravenously over more than 2 hours on Day 1 every 2 weeks, starting from Cycle 2 (after genetic testing results are available). Continue through induction and maintenance until disease progression or unacceptable toxicity.
