E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To test the synergistic effect of the combined treatment with low dose ASA plus MET given for 1 year to reduce the expression of NFκB (primary endpoint) in unaffected colonic tissue in patients with removed CRC. |
Testare ad un anno l'effetto sinergico del trattamento combinato con ASA a basse dosi e MET in pazienti operati di tumore al colon, nel ridurre l’espressione del biomarcatore NFκB nel tessuto sano dei pazienti. L’endpoint primario è definito come la differenza nei livelli di espressione di NFκB post- e pre-trattamento. |
|
E.2.2 | Secondary objectives of the trial |
To test the effect of treatment with ASA and MET, in combination and independently, on the following secondary endpoints: •The change in IHC expression levels of pS6K, p53, beta-catenin, PI3K •The change in the circulating biomarkers IL-6, CRP, VEGF and HOMA index •The gene expression levels of candidate genes , pathways and genome-wide expression profile in colon unaffected biopsy tissue. To define the blood and tissue drug levels of metformin, • To genetically characterize the primary colorectal carcinomas using NGS and determine their association with treatment response. •To study the treatment tolerability comparing incidence and grade of toxicities among arms •To study the serum concentrations of TBx as a biomarker of treatment adherence,to be correlated with biomarker modulation and toxicity. •To evaluate the effect of treatment on psychological variables and cancer related fatigue. |
•La differenza (post-pretrattamento) nei livelli di espressione di pS6K, p53, beta-catenina, PI3K, nel tessuto sano dei pazienti; •La differenza nei livelli circolanti di IL-6, CRP, VEGF e indice HOMA •La modulazione dell’espressione genica di un set di geni candidati e coinvolti nel processo di cancerogenesi, pathways e il profilo genomico nel tessuto sano dei pazienti; • Determinare i livelli di MET nel sangue e nel tessuto sano • Caratterizzare geneticamente il tumore colorettale primitivo attraverso sequenziamento NGS in associazione alla risposta al trattamento. • Studiare la tollerabilità del trattamento confrontando l’incidenza e il grado di tossicità per ogni braccio di trattamento; • Studiare le concentrazioni seriche di TxB2 come biomarcatore di aderenza al trattamento da correlare con la modulazione dei biomarker e la tossicità. • Valutare l'effetto del trattamento sulle variabili psicologiche, stili di vita e sui sintomi associati al cancro
