简要总结

The primary objective is to evaluate the effect of doubling the dose of bevacizumab in patients with mCRC treated in 1st line with a bevacizumab-based chemotherapy regimen whose trough serum concentration of bevacizumab is ≤ 15.5 mg /L on day 14 of the first administration of bevacizumab on progression-free survival (PFS).

入选标准

  • Adult patients ≥18 years old
  • Signature of free, written and informed consent by the patient;
  • Affiliation to a French social security system.
  • Randomization criteria in the experimental phase: - 1st residual serum concentration (Cres) of bevacizumab ≤ 15.5 mg/L measured just before the 2nd infusion of bevacizumab (D14).
  • ECOG Performance status (PS) 0-2
  • Having a histologically proven metastatic colorectal adenocarcinoma (on primary tumor and/or metastases) that is inoperable and well documented, i.e. not compatible with complete oncological resection at inclusion
  • For whom treatment with bevacizumab is indicated
  • For women of childbearing age: effective contraception
  • No prior treatment with palliative chemotherapy for metastatic disease (in case of adjuvant treatment, interval between the end of chemotherapy and relapse > 6 months)
  • At least one evaluable or measurable lesion assessed by computed tomography (CT) according to RECIST v1.1 criteria

排除标准

  • Patient with a known contraindication to first-line chemotherapy based on bevacizumab
  • Patient under guardianship, curatorship or safeguard of justice.
  • Inadequate hematological, hepatic or renal function
  • Contraindication to bevacizumab (major surgery within 28 days, risk of arterial thrombosis, risk of bleeding, deep vein thrombosis without effective anticoagulant treatment or unbalanced anticoagulant treatment)
  • In the event of brain metastases, their treatment (surgery and/or radiotherapy) must have been completed more than 4 weeks before the first cycle of chemotherapy under study
  • Serious non-healing wound, active ulcer or untreated bone fracture: ° Other neoplasia (recent or current history), except carcinoma in situ of the cervix treated adequately, localized basal cell or squamous cell carcinoma of the skin managed with curative intent ° Neoplasia in complete remission for more than 5 years.
  • Other illness, which, according to the doctor, is life-threatening to the patient and/or which is uncontrolled
  • Primary tumor present and symptomatic (occlusion, hemorrhage)
  • Pregnant or breastfeeding women
  • Patients unable to give consent

结局指标

主要结局

The primary endpoint is progression-free survival (PFS)

The primary endpoint is progression-free survival (PFS)

次要结局

  • 1. Safety profile defined by the number of adverse events classified according to the NCI-CTCAE5.0 classification. Particularly focused on AEs which are known to be linked to bevacizumab: hypertension, proteinuria, etc.
  • 2. Overall survival defined as the time elapsed between the date of randomization and death (all causes),
  • 3. Rate of best objective tumor response according to RECIST v1.1 criteria (evaluated over the entire duration of treatment).
  • 4. Depth of tumor response defined as the percentage of tumor reduction observed at the lowest point.
  • 5. Secondary resection of metastases (assessed over the entire treatment period)
  • 6. Quality of life: EORTC QLQ-C30 and EQ5D-5L.
  • 7. Serum concentrations of bevacizumab on day 14 of the first administration, and at 2 months from randomization (= 3 months from day 1 of the first cycle).
  • 8. Medical-economic analysis: estimation of the Differential Cost-Utility Ratio expressed as cost per QALY gained (year of life provided on quality) and the Differential Cost-Effectiveness Ratio expressed as cost per year of life gained.
