E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to determine whether, following an integrated RT approach, Abiraterone Acetate in ombination with low-dose prednisone and ADT is superior to ADT alone in improving EFS in hormone naïve subjects diagnosed with very high-risk prostate cancer. |
L’ obiettivo primario dello studio è:
Sopravvivenza Libera da Eventi (EFS) rappresentato dall’intervallo tra la randomizzazione e la recidiva biochimica (PSA-relapse), locale, recidiva a distanza o morte per qualsiasi causa. |
|
E.2.2 | Secondary objectives of the trial |
Safety; Biochemical Response Rate (PSA Response); overall survival, time to death due to prostate cancer; Biological end-points. |
Sopravvivenza globale (OS)
Sopravvivenza cancro-specifica.Altri endpoints di efficacia: tasso di risposta biochimica (secondo i criteri PCWG2); sicurezza (sec. criteri RTOG e NCI CTC); endpoints biologici |
|
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 |
Two blood samples of 8 ml each will be drawn at baseline and at the time of disease progression or end of follow-up in responding patients to extract host germline and circulating tumor DNA.
The following genetic polymorphisms associated with disease progression to castration-resistant prostate cancer will be investigated:
1) androgen receptor-binding sites (ARRDC3 rs2939244, FLT1 rs9508016, and SKAP1 rs6504145); 2) CYP17A1 gene (rs743572, rs6162, rs6163, and rs1004467); 3) steroid transport proteins encoded by the solute carrier (SLCO) gene family (SLCO2B1 rs12422149 and SLCO1B3 rs4149117) that mediate the uptake of steroids into prostate cancer cells and thereby influence the clinical response to androgen suppression and 4) steroid 5-α-reductase type 2 (SRD5A2, rs523349C) gene that encodes a prostatic enzyme critical for androgen metabolism (irreversible conversion of testosterone into the more potent androgen, dihydrotestosterone).
The polymorphisms will be investigated in the host germline DNA and in circulating DNA released from tumor to ascertain whether a genetic evolutionary process in the androgen response machinery occurs in tumors that undergo clinical progression. |
L’analisi genetica ha lo scopo di valutare l’importanza delle variazioni di sequenza dei seguenti geni:
1) steroide 17-alfa-mono-ossigenasi che trasforma due ormoni, il 17-idrossi-progesterone e il 17-idrossi-pregnenolone in ormoni androgeni attivi che stimolano la crescita del tessuto prostatico normale e delle cellule malate in esso contenute;
2) sito di legame dei recettori dell’ormone testosterone sul DNA; questa regione del gene è molto importante per regolare la stimolazione del testosterone sul tessuto prostatico normale e sulle cellule malate in esso contenute;
3) sistema di trasporto cellulare degli steroidi (siglato SLCO2B1 e SLCO1B3) che viene impiegato dalle cellule normali, ma soprattutto da quelle malate, per acquisire testosterone dall’ambiente esterno per stimolare la loro crescita;
4) steroide 5-alfa-reduttasi di tipo 2 che trasforma il testosterone nel suo ormone androgeno molto più potente, il diidrotestosterone che stimola in modo potente la crescita normale e patologica del tessuto prostatico. |
