Clinical trials

The European Union Clinical Trials Register   allows you to search for protocol and results information on:
  • interventional clinical trials that were approved in the European Union (EU)/European Economic Area (EEA) under the Clinical Trials Directive 2001/20/EC
  • clinical trials conducted outside the EU/EEA that are linked to European paediatric-medicine development

  • EU/EEA interventional clinical trials approved under or transitioned to the Clinical Trial Regulation 536/2014 are publicly accessible through the
    Clinical Trials Information System (CTIS).


    The EU Clinical Trials Register currently displays   43851   clinical trials with a EudraCT protocol, of which   7283   are clinical trials conducted with subjects less than 18 years old.   The register also displays information on   18700   older paediatric trials (in scope of Article 45 of the Paediatric Regulation (EC) No 1901/2006).

    Phase 1 trials conducted solely on adults and that are not part of an agreed paediatric investigation plan (PIP) are not publicly available (see Frequently Asked Questions ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2 Objective of the trial
    E.2.1Main objective of the trial
    1. To compare pathologic complete response (pCR) rates obtained in Arm A (preoperative enfortumab vedotin [EV] + pembrolizumab and radical cystectomy [RC] + pelvic lymph node dissection [PLND]) versus Arm B (neoadjuvant gemcitabine + cisplatin and RC + PLND).
    2. To compare event-free survival (EFS) in Arm A (perioperative EV + pembrolizumab and RC + PLND) versus Arm B (neoadjuvant gemcitabine + cisplatin and RC + PLND).
    1. confrontare i tassi di risposta completa patologica (pCR) ottenuti nel braccio A (enfortumab vedotin [EV] + pembrolizumab in fase preoperatoria e cistectomia radicale [RC] + dissezione dei linfonodi pelvici [PLND]) rispetto al braccio B (gemcitabina + cisplatino neoadiuvante e RC + PLND)
    2. confrontare la sopravvivenza libera da eventi (EFS) nel braccio A (EV + pembrolizumab in fase perioperatoria e RC + PLND) rispetto al braccio B (gemcitabina + cisplatino neoadiuvante e RC + PLND)
    E.2.2Secondary objectives of the trial
    1. To compare overall survival (OS) in Arm A (perioperative EV+pembrolizumab & RC + PLND) versus Arm B (neoadjuvant gemcitabine + cisplatin & RC + PLND).
    2. To assess disease-free survival (DFS) in Arm A (perioperative EV+pembrolizumab & RC + PLND) & Arm B (neoadjuvant gemcitabine + cisplatin & RC + PLND), participants who are disease free after surgery.
    3. To compare rate of pathologic downstaging (pDS) in Arm A (preoperative EV+pembrolizumab & RC + PLND) & Arm B (neoadjuvant gemcitabine + cisplatin & RC + PLND.
    4. To evaluate safety & tolerability of perioperative EV+pembrolizumab + RC + PLND in Arm A.
    5. To evaluate changes from baseline in health-related quality of life (HRQoL) & time to deterioration, using 2 general instruments (European Organization for Research & Treatment of Cancer [EORTC] QoL questionnaire-Core 30 [QLQ-C30], & European Quality of Life [EuroQoL]- 5 Dimensions, 5-level Questionnaire [EQ-5D-5L]), & 1 disease-specific instrument (Bladder Cancer Index [BCI]).
    1. confrontare la sopravvivenza globale (OS) nel braccio A (EV + pembrolizumab in fase perioperatoria e RC + PLND) rispetto al braccio B (gemcitabina + cisplatino neoadiuvante e RC + PLND)
    2. valutare la sopravvivenza libera da malattia (DFS) nei partecipanti del braccio A (EV + pembrolizumab in fase perioperatoria e RC + PLND) e del braccio B (gemcitabina + cisplatino neoadiuvante e RC + PLND) liberi da malattia dopo l’intervento chirurgico
    3. confrontare il tasso di downstaging patologico (pDS) nel braccio A e nel braccio B
    4. valutare la sicurezza e la tollerabilità di EV + pembro in fase periop. + RC + PLND nel braccio A.
    5. valutare i cambiamenti rispetto al basale nella qualità della vita correlata alla salute (HRQoL) e nel tempo al deterioramento, utilizzando 2 strumenti generali [EORTC]-Core 30 [QLQ-C30], & Qualità della vita europea [EuroQoL] - 5 Dimensioni, Questionario a 5 livelli [EQ-5D-5L]) e 1 strumento specifico per la malattia (Bladder Cancer Index [BCI]).

    E.3Principal inclusion criteria
    1. Has a histologically confirmed diagnosis of urothelial carcinoma (clinical stage T2-T4aN0M0 or T1-T4aN1M0) with predominant (>=50%) urothelial histology and PD-L1 expression (CPS >=10 or CPS <10, for PD-L1 not evaluable refer to inclusion criterion #4) to be confirmed by BICR (central pathology and/or central imaging assessment).
    • T1 disease (eligible only with N1 disease) and T2 disease will be confirmed by central pathology review and T3, T4a, N0 and N1 disease will be confirmed by central imaging review
    • Participants with mixed histology are eligible provided the urothelial component is >=50% as noted above (participants whose tumors contain predominant (>=50%) plasmacytoid variant are not eligible)
    • Participants whose tumors contain any component of neuroendocrine histology are not eligible
    • Urothelial carcinomas not originating from the bladder (eg, upper tract [ureters, renal pelvis], urethra) are not eligible. Urothelial carcinomas invading into the prostatic stroma with no histologic muscle invasion are allowed, provided that the extent of disease is confirmed via imaging.
    2. Has clinically non-metastatic bladder cancer (N<=1, M0) determined by imaging (CT or MRI of the chest/abdomen/pelvis), confirmed by BICR.
    3. Is deemed eligible for RC + PLND by a urologist and/or oncologist and agrees to undergo curative intent standard RC + PLND (including prostatectomy if applicable) as per AUA/ASTRO/ASCO/SUO guidelines.
