Brief summary
This phase 2 trial aims to evaluate the continued use of bevacizumab with raltitrexed and oxaliplatin combination versus FOLFOX6 plus bevacizumab in patients with metastatic colorectal cancer whose disease has progressed after irinotecan-based chemotherapy.
Detailed description
Eligible patients are randomly allocated to receive either bevacizumab with raltitrexed and oxaliplatin combination or bevacizumab with FOLFOX 6 combination. Random allocation schedule is performed using a minimization technique for the following stratification factors: * Center * Number of metastatic sites: 1 versus \> 1 * Bevacizumab-based first-line therapy: Yes versus No
Interventions
Bevacizumab 5 mg/kg administered as an iv infusion for 1h30, then for 1h and for 30 min. at the following cycles, respectively. Oxaliplatin 85 mg/m² administered as an iv infusion for 2h Elvorine 200 mg/m² administered as an iv infusion for 2h 5FU 400 mg/m2 bolus then 5FU 2,400 mg/m² iv infusion for 46h D1=D15 (12 cycles)
Bevacizumab 7.5 mg/kg administered as an iv infusion for 1h30, then administered for 1h and 30 min at the following cycles, respectively. Oxaliplatin 130 mg/m² administered as an iv infusion for 2h Raltitrexed 3 mg/m² administered as an iv infusion for 15 min

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Disease-free survival | 6 months | DFS is estimated from the date of randomization until the first date of objectively documented event or death |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Treatment-related toxicity | 6 months | Treatment-related toxicity is evaluated according to the NCI-CTCAE v.4 criteria. |
| Objective response rate | Every 9 weeks | Objective response rate is evaluated according to the RECIST V 1.1 criteria. |
| Overall survival | unk | OS is estimated from the date of randomization until the date of death from any cause |
| Cost-effectiveness study | 6 months | The cost-effectiveness study includes the number of hospital stays (treatment and toxicity), the global cost of treatments, and the cost of hospital stays due to treatment-induced toxicity |
| Quality of life by using the quality of life questionnaire score | 6 months | Quality of life is measured using the QLQ-C30 questionnaire |
