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   32829   clinical trials with a EudraCT protocol, of which   5307   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.2.2Secondary objectives of the trial
    The following secondary objectives will be evaluated across the ten specified tumour types (Groups A-J):

    -To evaluate how long the response to treatment lasts (duration of response), based on imaging assessments in participants who receive Pembrolizumab and the relationship between durations of response and physiology/genetic substances in the tumour.

    -To evaluate the length of time during or after treatment that the disease does not worsen (progression free survival), based on imaging assessments, in participants receiving Pembrolizumab and the relationship between the length of this time and physiology/genetic substances in the tumour.

    - To evaluate the overall survival in participants receiving Pembrolizumab and the relationship between overall survival and physiology/genetic substances in the tumour.

    The following secondary objectives will be evaluated across all tumour types (Groups A-K):

    -To determine the safety and tolerability of Pembrolizumab

    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 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. Be willing and able to provide written informed consent/assent for the trial. The subject may also provide consent/assent for Future Biomedical Research. However, the subject may participate in the main trial without participating in Future Biomedical Research.
    2.Be ≥18 years of age on the day of signing informed consent.
    3. Have a histologically or cytologically-documented, advanced (metastatic and/or unresectable) solid tumor that is incurable and for which prior standard first-line treatment has failed. Patients must have progressed on or be intolerant to therapies that are known to provide clinical benefit. There is no limit to the number of prior treatment regimens.
    4. Have one of the following advanced (unresectable and/or metastatic)
    tumor types:
    (A) Anal Squamous Cell Carcinoma,
    (B) Biliary Adenocarcinoma (gallbladder or biliary tree (intrahepatic or
    extrahepatic cholangiocarcinoma) except Ampulla of Vater Cancers,
    (C) Neuroendocrine Tumors (well- and moderately-differentiated), of the lung, appendix, small intestine, colon, rectum, or pancreas,
    (D) Endometrial Carcinoma (sarcomas and mesenchymal tumors are excluded),
    (E) Cervical Squamous Cell Carcinoma,
    (F) Vulvar Squamous Cell Carcinoma,
    (G) Small Cell Lung Carcinoma,
    (H) Mesothelioma (Malignant Pleural Mesothelioma),
    (I) Thyroid Carcinoma (Papillary or Follicular Subtypes),
    (J) Salivary Gland Carcinoma (sarcomas and mesenchymal tumors are excluded)
    (K) Any advanced solid tumor (except CRC), which is MSI-H.

    5. Have submitted an evaluable tissue sample for biomarker analysis from a tumor lesion not previously irradiated (exceptions may be considered after consultation with and approval by the Sponsor) (See Procedure Manual for detailed instructions). The tumor tissue submitted for analysis must be from a single tumor tissue specimen and of sufficient quantity and quality to allow assessment of ALL required primary biomarkers.
    6. If enrollment in Groups A-J has moved to biomarker enrichment, have a tumor that is positive for one or more of the pre-specified primary biomarker(s), as assessed by the central laboratory. These enrichment biomarkers may be PD-L1 expression by IHC (at a percentage to beprespecified), a positive tumor RNA GEP score (at a prespecified cut-off), and/or tumor MSI-H.
    7. Have radiologically measurable disease based on RECIST 1.1. Independent central radiologic review must confirm the presence of radiologically measureable disease based on RECIST 1.1 for the subject to be eligible to participate in the trial (see Site Imaging Manual for detailed instructions). Tumor lesions situated in a previously irradiated area are considered measurable if progression has been demonstrated in such lesions.
    8. Have a performance status of 0 or 1 on the ECOG Performance Scale. This performance status must be confirmed within 3 days prior to the first dose of pembrolizumab or the subject must be excluded.
    9. Life expectancy of at least 3 months.
    10. Demonstrate adequate organ function as described in the protocol
    11. Female subjects of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of trial medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
    12. Female subjects of childbearing potential must be willing to use an adequate method of contraception, for the course of the study through 120 days after the last dose of trial medication.
    13. Male subjects of childbearing potential must agree to use an adequate method of contraception, for the course of the study through 120 days after the last dose of trial medication.

    E.5.1.1Timepoint(s) of evaluation of this end point
    The trial incorporates an adaptive design in which multiple interim analyses may be performed. Results will be reviewed by the study team. The cutoffs for the three primary biomarker assays will be selected and specified before the first interim analysis. Details regarding the timing and conduct of the initial interim analysis will be further clarified in the sSAP. The planned sample size may be modified based on the interim results. The timing of additional interim analyses, the final analysis as well as the analysis plan will be documented in the sSAP. The sSAP will also be updated as the trial evolves.
    The primary endpoint of ORR will be used for all interim analyses with or without a confirmatory assessment; however, a confirmatory assessment is required for the final analysis
