E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess the impact of TOOKAD Soluble VTP on the rate of absence of definite cancer using patients on active surveillance as a comparison (co-primary objective A). To determine the difference in rate of treatment failure associated with observed progression of disease from low risk prostate cancer to moderate or higher risk prostate cancer in men who undergo TOOKAD Soluble VTP compared to men on Active Surveillance (co-primary objective B). |
Valutare l’impatto della VTP con TOOKAD Soluble sulla percentuale di assenza di tumore facendo il confronto con pazienti soggetti a sorveglianza attiva (obiettivo co-primario A). Determinare la differenza di percentuale di fallimento del trattamento associato all’osservazione del progredire della malattia da tumore della prostata a basso rischio a tumore della prostata a rischio moderato o alto in pazienti sottoposti a VTP con TOOKAD Soluble rispetto a pazienti sottoposti a sorveglianza attiva (obiettivo co-primario B). |
|
E.2.2 | Secondary objectives of the trial |
To determine the differences between men who undergo TOOKAD Soluble VTP and men on active surveillance with regard to: • the rate of additional prostate cancer radical therapy • the total cancer burden in the prostate • the rate of adverse events • the rate of incontinence, erectile dysfunction, urinary symptoms • the rate of severe prostate cancer related events: cancer extension T3, metastasis and prostate cancer related death. The overall quality of life will be recorded for potential utility and descriptive studies. |
Determinare le differenze tra pazienti sottoposti a VTP con TOOKAD Soluble e pazienti sottoposti a sorveglianza attiva relativamente a quanto segue: • la percentuale di terapia radicale aggiuntiva nel tumore della prostata • l’incidenza totale del tumore della prostata • la percentuale di eventi avversi • la percentuale di incontinenza, disfunzione erettile e sintomi urinari • la percentuale di eventi severi legati al tumore alla prostata: estensione del tumore a T3, metastasi e decesso legato al tumore della prostata La qualita' globale della vita verra' registrata a scopo di potenziale utilizzo e per gli studi descrittivi. |

E.5 End points |
E.5.1 | Primary end point(s) |
Co-primary endpoint `A` Absence of any histological result definitely positive for cancer. Co-primary endpoint `B` Failure of treatment due to progression of cancer from low to moderate or higher risk over the 24 month follow- up. Moderate or higher risk is defined as the observation of: • More than 3 cores positive for cancer when considering all histological examination available during follow-up of study; • or any Gleason primary or secondary pattern 4 or more; • or at least one cancer core length greater than 5 mm; • or PSA>10ng/mL in 3 consecutive measures; • or any T3 prostate cancer; • or metastasis; • or prostate cancer related death. |
End-point primario End-point co-primario ‘A’ Assenza di esiti istologici positivi al tumore End-point co-primario ‘B’ Fallimento del trattamento dovuto alla progressione del tumore da rischio basso a moderato o alto nel periodo di follow-up di 24 mesi. Il rischio moderato o alto e' definito dall’osservazione di quanto segue: - Oltre 3 core positivi al tumore prendendo in considerazione tutti gli esami istologici disponibili durante il periodo di follow-up dello studio; - o pattern di Gleason 4 primari o secondari o superiori; - o almeno una lunghezza del core del tumore maggiore di 5 mm; - o PSA>10ng/mL ( in 3 misurazioni consecutive); - o tumore della prostata T3, - o metastasi; - o decesso legato al tumore della prostata |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Histological changes are assessed using 12-core TRUS biopsies or a density of 1 core per 2 cc of prostate tissue in case of significant prostate shrinking has occurred, performed at 12 months (+/- 2 months) and using saturated TRUS biopsy of 1 core per 2 cc (up to 24 cores) at 24 months or any other pathology result obtained during the study planned or not. The follow-up is done to loss to follow-up, early study termination or 24 months after randomisation, whatever the treatment events occurring (drop-out, radical treatment). |
I cambiamenti istologici sono valutati mediante biopsie TRUS a 12 core, o con la densita' di 1 core per 2 cc di tessuto prostatico qualora si sia verificato un significativo restringimento della prostata, eseguite a 12 mesi (+/- 2 mesi) e utilizzando la biopsia TRUS a saturazione di 1 core per 2 cc (fino a 24 core) a 24 mesi o altri eventuali esiti patologici ottenuti durante lo studio pianificato o meno. Il follow-up viene effettuato fino a quando i pazienti non sono persi al follow up, fino alla conclusione precoce dello studio o 24 mesi dopo la randomizzazione, qualunque siano gli eventi del trattamento che si sono verificati (drop-out, trattamento radicale). |

E.5.2 | Secondary end point(s) |
- Notification of initiation of radical therapy - Total number of cores positive for cancer - Patients’ reported outcome measures (PROMs) impairment: urinary symptoms, erectile functions - Adverse event reporting - Severe prostate cancer related events: cancer extension to T3, metastasis or prostate cancer-related death Quality of life will also be described. |
- Comunicazione di inizio di terapia radicale - Numero totale di core positivi al tumore - Peggioramento dei patients’ reported outcome (PROM) dei pazienti, ossia gli indicatori di risultato espressi dai pazienti: sintomi urinari, funzioni erettili - Segnalazione di eventi avversi - Eventi gravi legati al tumore della prostata: estensione del tumore a T3, metastasi o decesso connesso al tumore della prostata La qualita' della vita sara' ugualmente descritta. |
