E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess if regorafenib is active enough, in terms of 6-month progression-free rate, to warrant further comparative studies in patients with RAS-mutant advanced colorectal cancer who have progressed after first-line oxaliplatin-based chemotherapy plus bevacizumab. |
Valutare se regorafenib sia sufficientemente attivo, in termini di tasso di pazienti liberi da progressione a 6 mesi, da motivare studi di tipo comparativo di fase 3 in pazienti affetti da carcinoma colorettale avanzato con mutazioni di RAS, che siano in progressione dopo un trattamento di prima linea con chemioterapia contenente oxaliplatino in combinazione con bevacizumab. |
|
E.2.2 | Secondary objectives of the trial |
To describe: - toxicity - objective response rate - progression free-survival - overall survival.
To explore the prognostic and predictive value of: - circulating endothelial (CEC) and progenitor (CEP) cells (at baseline and during treatment) - circulating angiogenic factors (i.e. angiopoietin, sTIE, Ang-2, VEGF isoforms, PDGF, PlGF, sVEGF-R-1 and -2 isoforms) - circulating cytokines profiling - circulating miRNA profiling - circulating free DNA (cfDNA) mutations - VEGF, VEGFR, CYP3A4 and UTG1A9 polymorphisms - early assessment of metabolic response with PET-CT scan.
|
Descrivere: - tossicità; - risposte obiettive; - sopravvivenza libera da progressione; - sopravvivenza globale.
Esplorare il valore prognostico e predittivo di: - cellule endoteliali circolanti (CEC) e progenitrici (CEP) (al basale e durante il trattamento) - fattori angiogentici circolanti (angiopoietina, sTIE, Ang-2, isoforme di VEGF, PDGF, PlGF, isoforme sVEGF-R-1 e -2) - profilo di citochine circolanti - profilo di miRNA circolanti - mutazioni del DNA libero circolante (circulating free DNA, cfDNA) - polimorfismi di VEGF, VEGFR, CYP3A4 e UTG1A9 - valutazioni precoce della risposta metabolica misurata con PET-TC.
