Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   38470   clinical trials with a EudraCT protocol, of which   6318   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).
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Merck 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
    E.3Principal inclusion criteria
    1. Have histologically confirmed diagnosis of locoregional MCC that has recurred following standard locoregional therapy with surgery and/or radiation therapy and is not amenable to local therapy or metastatic MCC (Stage IV) as per American Joint Committee on Cancer (AJCC) 8th edition guidelines
    2. Have been untreated for advanced or metastatic disease except as follows:
    a. Prior intratumoral therapy will be permitted

    3. Have at least 1 measurable lesion by computed tomography (CT) or magnetic resonance imaging (MRI) per RECIST 1.1 criteria as determined by the local site investigator/radiology assessment. Measurable disease will be verified by BICR prior to treatment allocation. Lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions
    4. Toxic effect(s) of the most recent prior therapy have resolved to Grade 1 or less (except alopecia). If participant received major surgery or radiation therapy of >30 Gy, they must have recovered from the toxicity and/or complications from the intervention
    5. Be male or female and at least 12 years of age, at the time of signing the informed consent/assent
    6. Contraceptive use by men should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies
    7. Contraceptive use by women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
    • 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 woman of childbearing potential (WOCBP)
    OR
    - 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 120 days (corresponding to the time needed to eliminate any study intervention) after the last dose of study intervention
    - A WOCBP must have a negative highly sensitive pregnancy test (urine or serum as required by local regulations) within 72 hours 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
    8. Participant (or legally acceptable representative if applicable) provides written informed consent/assent for the study and agrees to OS data collection until the study endpoints are reached. The participant may also provide consent/assent for future biomedical research; however, the participant may participate in the main study without participating in future biomedical research
    9. Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 or Lansky Play-Performance Scale (LPS) ≥50 for pediatric participants up to and including 16 years of age
