E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary aim of the study will be to evaluate the disease control rate (partial response, complete response, disease stability for at least 12 months from the beginning of treatment) of patients subjected to PRRT. |
L¿obiettivo primario dello studio sar¿ di valutare il controllo di malattia (risposta parziale, risposta completa, stabilit¿ di malattia per almeno 12 mesi dall¿inizio del trattamento) dei pazienti sottoposti a PRRT. |
|
E.2.2 | Secondary objectives of the trial |
The secondary aims will be: ¿ To assess the safety profile of PRRT (acute and late toxicity), especially as regards critical organs (renal parenchyma and bone marrow); ¿ To evaluate progression-free survival time (PFS) and overall survival time (OS); ¿ to correlate the response to PRRT with the degree of histological differentiation at the time of diagnosis and the stage of disease at the time of enrollment in this clinical study; ¿ To correlate, basing on dosimetric evaluation, the activity and toxicity of treatment, respectively, with the dose to the tumour and the critical organs; ¿ To analyse any changes in the quality of life (QOL) by the detection of subjective parameters according to the EORTC QLQ-C30 scheme; ¿ To evaluate the predictive value of PET-TC with 18f-FDG on PFS and OS. |
Gli obiettivi secondari saranno: ¿ valutare il profilo di sicurezza della PRRT (tossicit¿ acuta e tardiva), soprattutto per quel che riguarda gli organi critici (parenchima renale e midollo osseo); ¿ valutare il tempo di sopravvivenza libera da progressione (PFS) e il tempo di sopravvivenza globale (OS); ¿ correlare la risposta alla PRRT con il grado di differenziazione istologica al momento della diagnosi e lo stadio di malattia al momento dell¿arruolamento nel presente studio clinico; ¿ correlare, sulla base delle valutazioni dosimetriche, l¿attivit¿ e la tossicit¿ del trattamento rispettivamente con la dose al tumore e agli organi critici; ¿ analizzare le eventuali modificazioni della qualit¿ della vita (QoL) attraverso la rilevazione dei parametri soggettivi secondo lo schema EORTC QLQ-C30; ¿ valutare il valore predittivo della PET-TC con 18F-FDG sulla PFS e sulla OS.

E.5 End points |
E.5.1 | Primary end point(s) |
The "intent-to-treat (ITT)" population is the population of all patients enrolled to participate in this protocol. The activity population (AP) is represented by all ITT patients except those who, although recruited during the preliminary phase, will not undergo-for any reason-the actual therapeutic treatment. The AP coincides, in this study, with the safety population (SP) and includes all patients who have received at least one therapy cycle. Primary endpoint analysis Each patient will be categorized into one of the following categories: 1) Complete response 2) Partial response 3) Disease stability for at least 12 months from the beginning of treatment 4) Disease progression 5) Early death by tumour 6) Early death for toxicity 7) Early death for other causes 9) not assessable for insufficient data. Patients in categories 1, 2, 3 will be treated as under disease control. Patients in categories 4, 5, 6, 7, 8, 9 will be considered as failures of therapy. |
La popolazione “intention-to-treat (ITT)” è la popolazione di tutti i pazienti arruolati per partecipare al presente protocollo. L’activity population (AP) è rappresentata da tutti i pazienti dell’ITT eccetto quelli che, benché reclutati durante la fase preliminare, non si sottoporranno - per qualsiasi motivo – all’effettivo trattamento terapeutico. L’AP coincide, nel presente studio, con la safety population (SP) e include tutti i pazienti che hanno ricevuto almeno un ciclo di terapia. Analisi dell’endpoint primario Ogni paziente verrà classificato in una delle seguenti categorie: 1) risposta completa 2) risposta parziale 3) stabilità di malattia per almeno 12 mesi dall’inizio del trattamento 4) progressione di malattia 5) morte precoce per tumore 6) morte precoce per tossicità 7) morte precoce per altre cause 9) non valutabile per dati insufficienti. I pazienti nelle categorie 1,2,3 verranno considerati come sotto controllo di malattia. I pazienti nelle categorie 4,5,6,7,8,9 verranno considerati come fallimenti della terapia. |

E.5.1.1 | Timepoint(s) of evaluation of this end point |
An interim analysis will be carried out one year after the start of the enlistment to assess the activity of treatment, toxicity and compliance with the Protocol and subsequent analysis after the end of the study. |
Si prevede un’analisi ad interim da eseguirsi a un anno dall’inizio dell’arruolamento per valutare l’attività del trattamento, la tossicità e la compliance al protocollo e successive analisi dopo la fine dello studio. |
|
E.5.2 | Secondary end point(s) |
PFS and OS will be evaluated by the Kaplan-Meier method (Kaplan El, Meier P., J am Stat Assoc 1958); The analysis will be performed on the AP population. Dose estimates for the tumour and renal parenchyma may be correlated with disease control, PFS, OS, QOL and with acute and late toxicity to the renal parenchyma by uni-multivariate analysis. All adverse events will be recorded and encoded according to the CTC-AE version 4.0 criteria in the safety population. |
PFS e OS verranno valutati con il metodo di Kaplan-Meier (Kaplan El, Meier P., J Am Stat Assoc 1958); l¿analisi verr¿ eseguita sulla AP population. Le stime della dose al tumore e al parenchima renale potranno essere correlate rispettivamente con il controllo di malattia, PFS, OS, QoL e con la tossicit¿ acuta e tardiva a carico del parenchima renale mediante analisi uni-multivariata. Tutti gli eventi avversi verranno registrati e codificati secondo i criteri CTC-AE versione 4.0 nella safety population. |
