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   43845   clinical trials with a EudraCT protocol, of which   7282   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
    In:
    Cohort A – Subjects with CIS at baseline (CIS only, Ta+CIS, or T1+CIS)
    And
    Cohort B – Subjects without CIS at baseline (High Grade Ta or Any Grade T1)

    To evaluate anti-tumor activity of pembrolizumab (MK-3475) by evaluating the absence of high risk NMIBC or progressive disease, as determined by cystoscopy, cytology, biopsy (if applicable), and radiologic imaging by central pathology and radiology review.
    E.2.2Secondary objectives of the trial
    To evaluate anti-tumor activity of MK-3475:
    Cohort A -CIS at baseline
    1. by CR rate of any disease
    2. by DOR of high risk NMIBC and any disease (responders only)
    3. in PD-L1+ subjects by CR rate of high risk NMIBC and any disease
    4. in PD-L1+ subjects by DOR of high risk NMIBC and any disease (responders only)
    5. in the study population and in PD-L1+ subjects by:
    a. DOR rate at specific time points of both high risk NMIBC and any disease (responders only)
    b. PFS, to worsening of grade or stage or death
    c. PFS, to muscle invasive or metastatic disease or death
    d. OS

    Cohort B -no CIS at baseline
    1. by DFS rate of any disease
    2. in PD-L1 + subjects by 12-month DFS rate of high risk NMIBC and any disease
    3. in the study population and in PD-L1+ subjects by:
    a. Overall DFS and 3-month/6-month DFS rates of high risk NMIBC and any disease
    b. PFS, to worsening of grade or stage or death
    c. PFS, to muscle invasive or metastatic disease or death
    d. OS
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Merck Sharpe & Dohme will conduct Future Biomedical Research on DNA (blood) specimens collected during this clinical trial. Such research is for biomarker testing to address emergent questions not described elsewhere in the protocol (as part of the main trial) and will only be conducted on specimens from appropriately consented subjects. The objective of collecting specimens for Future Biomedical Research is to explore and identify biomarkers that inform the scientific understanding of diseases and/or their therapeutic treatments. The overarching goal is to use such information to develop safer, more effective drugs, and/or to ensure that subjects receive the correct dose of the correct drug at the correct time.
