E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of the trial is to compare the efficacy of regorafenib versus placebo as maintenance treatment in patients who did not achieve a complete response after their standard treatment sequence (either at diagnosis or at first relapse) |
L’objectif principal de cet essai est de comparer l’efficacité d’un traitement de maintenance par regorafenib versus placebo chez les patients qui n’ont pas obtenu de réponse complète après leur traitement standard (au diagnostic ou lors de la première rechute). |
|
E.2.2 | Secondary objectives of the trial |
To determine in both arms:
• The Objective Response Rate (ORR),
• The Disease Control Rate (DCR),
• The Time to Treatment Failure (TTF),
• The Overall Survival
• The Quality of Life (EORTC QLQ-C30),
• The tolerance profile (NCI-CTC AE version 5)
In patients from the placebo arm who switched into the active treatment group, the following additional objectives will be studied from regorafenib initiation:
• The Progression-Free Survival (PFS)
• The Objective Response Rate (ORR)
• The Disease Control Rate (DCR)
• The Overall Survival
• The tolerance profile
|
Déterminer dans les deux bras :
• Le taux de réponse objective (ORR),
• Le taux de contrôle de la maladie (DCR),
• Le temps à échec du traitement (TTF),
• La survie globale,
• La qualité de vie (questionnaire EORTC QLQ-C30),
• Le profil de tolérance (NCI-CTC AE version 5).
Pour les patients du bras « placebo » qui passeront dans le bras « traitement expérimental », les objectifs supplémentaires suivants seront évalués depuis l’initiation du Regorafenib :
• La survie sans progression (PFS),
• Le taux de réponse objective (ORR),
• Le taux de contrôle de la maladie (DCR),
• La survie globale,
• Le profil de tolérance.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
In tumor environment (FFPE block pre-treatment [biopsy or surgery]): Multi-IF analysis to define CD3, CD20 and CD8 expression, T cell activation including KI67 / PD1, Tumor-Associated Macrophages, Dendritic cells, Expression of Immune checkpoints and ligands including PDL1 / L2.
Other research on blood samples (Plasma): Flow cytometry for phenotypic analysis, distribution of immune populations (T, B, NK, Monocytes and dendritic cells (cDC1, cDC2, pDC)) and adaptive (CD4 and CD8 T populations, Treg, B populations and plasma cells), quantification of CD146+ CECs (and plasma level of VEGF). |
