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   43886   clinical trials with a EudraCT protocol, of which   7296   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.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    To be eligible for inclusion in this study, the participant must:
    1. Have a histologically confirmed diagnosis of UC/MIBC (clinical stage T2 T4aN0M0 or T1 T4aN1M0) with predominant (≥50%) urothelial histology and PD-L1 expression (CPS ≥10 or CPS <10, for PD-L1 CPS score not evaluable refer to inclusion criterion #4) to be confirmed by BICR (central pathology and/or imaging):
    -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 neuroendocrine histology are not eligible.
    -UCs not originating from the bladder (eg, upper tract [ureters, renal pelvis], urethra) are not eligible.
    2. Have clinically non-metastatic bladder cancer (N≤1 M0) determined by imaging (CT or MRI of the chest/abdomen/pelvis), confirmed by BICR.
    3. Be deemed eligible for RC + PLND by a urologist and/or oncologist and agree to undergo curative-intent standard RC + PLND (including prostatectomy if applicable) as per AUA/ASTRO/ASCO/SUO guidelines.
    4. Have a TUR of a bladder tumor (obtained as early as 60days [+14days] prior to enrollment [providing documented informed consent]) that is submitted for central pathology assessment and adequate to determine urothelial histology and PD-L1 expression. (In the event the sample is not evaluable for PD L1, the participant will be
    assigned to the CPS <10 group for stratification).
    5. Have ECOG performance status of 0 or 1.
    6. Have adequate organ function (all screening labs should be performed within 14 days prior to randomization).
    7. Participant is male or female and at least 18 years of age inclusive, at the time of providing documented informed consent.
    8. Male participants are eligible to participate if they agree to the following during the intervention period and for at least the time needed to eliminate each study intervention after the last dose of study intervention. The length of time required to continue contraception for each study intervention is as follows:
    - Pembrolizumab: 0 days (no requirement)
    - Gemcitabine and/or cisplatin: 90 days

    -Refrain from donating sperm
    PLUS either:
    -Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent
    - Must agree to use contraception unless confirmed to be azoospermic (vasectomized or secondary to medical cause) as detailed below:
    *Agree to use a male condom plus partner use of an additional contraceptive method when having penile-vaginal intercourse with a WOCBP who is not currently pregnant.
    9. A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
    -Is not a WOCBP
    -Is a WOCBP and using a contraceptive method that is highly effective (with a failure rate of <1% per year), with low user dependency, or be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis), during the intervention period and for at least the time needed to eliminate each
    study intervention after the last dose of study intervention and agrees not to donate eggs (ova, oocytes) to others or freeze/store for her own use for the purpose of reproduction during this period. The length of time required to continue contraception for each study intervention is as follows:
    - Pembrolizumab: 120 days
    - Gemcitabine and/or cisplatin: 180 days.
    The investigator should evaluate the potential for contraceptive method failure (ie, noncompliance, recently initiated) in relationship to the first dose of study intervention.
    -A WOCBP must have a negative highly sensitive pregnancy test (urine or serum as required by local regulations) within 24 hours for urine or within 72 hours for serum) before the first dose of study intervention.
    -If a urine test cannot be confirmed as negative (eg, an ambiguous result), a serum pregnancy test is required. In such cases, the participant must be excluded from participation if the serum pregnancy result is positive.
    -The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
    10. The participant (or legally acceptable representative) has provided documented informed consent/assent for the study. The participant may also provide consent/assent for FBR. However, the participant may participate in the study without participating in FBR.
