Metastatic Colorectal Cancer
Conditions
Brief summary
The aim of BEVAMAINT is to improve benefic effect of maintenance therapy after a first line of induction chemotherapy for patients with colorectal cancer
Interventions
DRUGFluoropyrimidine
Option 1: Capecitabine 1250 mg/m2 twice daily (i.e. 2500 mg/m²/d) (D1 to D14, D1 = D22) For frail patients according to investigator evaluation capecitabine dose may be reduced to 1000 mg/m2 twice daily (2000 mg/m²/d). Or Option 2: Capecitabine 625 mg/m2 twice daily (i.e. 1250 mg/m²/d) (D1 to D21, D1 = D22) Or Option 3: LV5FU2 simplified (folinic acid 200 mg/m² (or Elvorin 400 mg/m²) IV during 2h followed by 5-FU bolus IV of 400 mg/m² during 10 min and IV continuous 5-FU at 2400 mg/m² during 46h). (D1=D15).
DRUGBevacizumab
Option 1 and Option 2 : D1 bevacizumab 7.5 mg/kg IV (D1=D21). See smPCs for infusion time of bevacizumab. Or Option 3: D1 bevacizumab 5 mg/kg IV (D1=D15). See smPCs for infusion time of bevacizumab

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The Time-to-Treatment Failure (TTF) | 8 months | Will be calculated from date of randomization (after the end of induction chemotherapy) to first radiological progression (according to RECIST 1.1) or death or start of a new chemotherapy (induction regimen or second line) or end of maintenance treatment without further chemotherapy, even if there is no radiological progression. Patients alive with no radiological progression and under maintenance treatment will be censored at the date of last news. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Progression-free survival (PFS1) | 16 months | Defined as the time between randomization and the first radiological progression (according to RECIST 1.1) or death (whatever occurs first). Patients alive and without progression will be censored at the date of last news. |
| Progression-free survival (PFS2) | 16 months | Defined as the time between the end of maintenance treatment (whatever the reason is) and the radiological progression after this end of maintenance treatment or death whatever the cause. Patients alive and without progression will be censored at the date of last news. |
| Overall Survival (OS) | 3 years | Defined as the time between randomization and death (any cause). Patients alive will be censored at the date of last news. |
| Safety | 3 years | Toxicities will be graded according to the NCI-CTC v 4.0 criteria before each cycle. |
| Quality of Life (QoL) | 3 years | Assessed at each evaluation with a questionnaire |
