E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Primary objective is to assess the effect of each of the 3 experimental interventions (aspirin, metformin or both, in combination with neoadjuvant induction chemotherapy (ICT) and preoperative chemoradiation (CRT)) compared to standard neoadjuvant ICT |
L’obiettivo primario è stabilire gli effetti di 3 interventi farmacologici sperimentali (aspirina, metformina o entrambi i trattamenti, in combinazione con la chemioterapia di induzione (ICT) e la radiochemioterapia (CRT)) |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to assess the effect of the experimental interventions compared to the standard neoadjuvant treatment with ICT followed by CRT |
L’obiettivo secondario è stabilire gli effetti degli interventi sperimentali in confronto al trattamento neoadiuvante standard con ICT seguito da CRT |

E.3 | Principal inclusion criteria |
Pathologically proven diagnosis of adenocarcinoma of the rectum by endoscopic biopsy within 56 days prior to randomisation.

Able to undergo induction chemotherapy, chemoradiotherapy and total mesorectal excision (TME). Distal part of the tumour within 0–12 cm of the anal verge (Note: intraperitoneal rectal cancer are excluded) |
•Diagnosi istopatologica di adenocarcinoma del retto, attraverso una biopsia endoscopica, entro 56 giorni prima della randomizzazione. •Cancro del retto localmente avanzato (definito tramite la classificazione TNM come Stadio II o III), sulla base del seguente workup diagnostico minimo: MRI della pelvi, CT torace-addome con mezzo di contrasto. •Non vi siano controindicazioni alla chemioterapia di induzione, radiochemioterapia ed escissione totale del mesoretto (TME). . parte distale del tumore entro 0-12 cm dal margine anale (nota: tumori rettali intraperitoneali sono esclusi) |
|
E.4 | Principal exclusion criteria |
Prior treatment for LARC (recurrent rectal tumours are excluded) or previous pelvic radiotherapy. Unequivocal evidence of established metastatic disease based on minimum diagnostic workup. Patients with equivocal lesions are eligible. Patients already taking daily aspirin and/or metformin for more than 4 weeks prior to randomisation. Hypersensitivity to salicylic acid compounds or prostaglandin synthetase inhibitors and to any of the excipients. Hypersensitivity to metformin or to any of the excipients |
•Pregresso trattamento per LARC (i tumori recidivi del retto sono esclusi) o pregressa radioterapia della pelvi. •Evidenza inequivocabile di malattia metastatica al workup diagnostico minimo. Pazienti con lesioni equivocabili sono eleggibili. •Pazienti già sotto terapia quotidiana con aspirina e/o metformina da più di 4 settimane prima della randomizzazione. •Ipersensibilità ai composti a base di acido salicilico o inibitori delle sintesi delle prostaglandine o di qualunque altro eccipiente. •Ipersensibilità alla metformina o a qualunque altro eccipiente |
