Main objective
Scope: Therapy, Efficacy
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).
Secondary objectives 8
- 1. Evaluate security (NCI-CTCAEv5.0),
- 2. Evaluate overall survival,
- 3. Evaluate the best objective tumor response rate (according to RECIST v1.1),
- 4. Evaluate the depth of the tumor response,
- 5. Evaluate the secondary resection rate,
- 6. Evaluate quality of life,
- 7. Study the pharmacokinetics of bevacizumab in mCRC according to the administered dose.
- 8. Medical-economic analysis: evaluate the efficiency of doubling the dose of bevacizumab in patients with mCRC whose initial residual serum concentration of bevacizumab is ≤ 15.5 mg/L, based on modeling.

|---|---|---|---|---|---|
| 1 | Sélection et recrutement des personnes se prêtant à la recherche Le screening des patients sera réalisé par les investigateurs associés, assistés éventuellement des techniciens d’étude clinique sous la responsabilité des investigateurs des établissements participant à cette étude. L’étude sera présentée à la personne dont la participation est sollicitée lors d’une consultation de suivi. La personne souhaitant participer à l’étude devra donner son consentement de participation écrit et un document d’information lui sera remis en amont.
|
Not Applicable | None | ||
| 2 | Inclusion Une visite d’inclusion permettra de vérifier les critères d'inclusion et de non-inclusion. Un bilan pré-thérapeutique (pour les femmes, test de grossesse sérique inclus) devra être réalisé. Il s’agira du bilan habituel et commun (= soin courant) pour tout patient initiant un traitement à base de bevacizumab en plus du bilan habituel nécessaire au suivi de sa maladie.
Après avoir éventuellement complété l'information et répondu aux questions que le patient pourrait encore avoir au sujet de l'étude, l’investigateur devra recueillir son consentement de participation. Ce document doit être impérativement daté et signé par le patient et l’investigateur lors de cette visite avant toute évaluation spécifique à l'étude. Les patients ayant signé un consentement de participation et répondant aux critères d’inclusion pourront ainsi être inclus dans cette étude.
A la visite d’inclusion, le bilan suivant (= intervention à l’étude) sera réalisé avant le début du traitement par bevacizumab :
- Questionnaires de Qualité de vie (QLQ-C30 et EQ5D-5L),
- Prélèvement sanguin (5-7 mL sur tube sec sans gel séparateur à bouchon rouge) pour effectuer un dosage sérique du bevacizumab (afin de vérifier l’absence d’interférence ou de traitement antérieur).
|
Not Applicable | None | ||
| 3 | Intervention La mesure de la concentration de bevacizumab à J14 sera réalisée de façon centralisée par le CePiBAc du CHRU de Tours, grâce à une méthode ELISA validée et publiée [ Ternant, Ther Drug Monit. 2010].
- La randomisation devra être effectuée au plus tard 24 à 48 heures avant le J1 du 3ème cycle
(les patients ayant une concentration sérique résiduelle > 15.5 mg/L, seront sortis d’étude).

- questionnaires de Qualité de vie (QLQ-C30 et EQ5D-5L)
- dosage du bevacizumab sérique résiduel (préciser date et heure du prélèvement)
Toutes les 12 semaines après inclusion :
- examen clinique avec : les signes vitaux (pression artérielle, pouls), statut OMS, poids,
- scanner thoraco-abdomino-pelvien
- bilan biologique ((NFS-plaquettes, Protéine C Réactive, ionogramme sanguin, créatininémie, bilan hépatique – ASAT, ALAT, Phosphatases alcalines, GGT, Bilirubinémie totale et conjuguée, LDH, lactates, bicarbonates, albuminémie, calcémie, phosphorémie, magnésémie, ACE, CA 19-9),
- questionnaires de Qualité de vie (QLQ-C30 et EQ5D-5L) .
Fin de traitement (pour progression, toxicité, perdu de vue, …) :
- examen clinique avec : les signes vitaux (pression artérielle, pouls), statut OMS, poids

- 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).
