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   43935   clinical trials with a EudraCT protocol, of which   7309   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.

    - Objective response rate;
    - Time to pain progression;
    - Time to opiate use for cancer-related pain;
    - Time to first skeletal-related event;
    - Quality of life.
    Safety profile including cumulative dose of docetaxel and Health Resource Use will be described for these subjects.
    E.2.3Trial contains a sub-study Yes
    E.2.3.1Full title, date and version of each sub-study and their related objectives
    Biomarker Sub-study:
    - Subjects in a subset of countries and sites will be invited to participate
    in a voluntary, exploratory, biomarker sub-study. For subjects who have
    consented to provide samples for this sub-study, blood samples for
    circulating biomarker analysis will be taken at the following timepoints:
    - Period 1: Week 1/Day 1 (pre dosing with enzalutamide), Week 5, Week
    13, and when subjects progress clinically (4 samples).
    - Period 2: Week 1/Day 1 (pre study drug in Period 2), Cycle 2 (Week 4),
    Cycle 5 (Week 13), Cycle 9 (Week 25), when subjects progress clinically
    or reach another endpoint in the study and at Follow-Up (30 days after
    last dose of IMP) (6 samples).
    - Any subject who consents to participate in the biomarker sub-study,
    but fails to provide a valid baseline sample for Period 1, may still
    participate in Period 2 of the biomarker sub-study. In this case, the last
    sample of Period 1 (the sample taken when they progress clinically)
    should be taken as part of the baseline for Period 2. Informed Consent
    for the biomarker samples must be taken before any samples are
    collected. Samples are to be handled according to the laboratory manual,
    and shipped to a central laboratory for processing.

    E.5 End points
    E.5.1Primary end point(s)
    The primary efficacy endpoint is PFS with progression defined as radiographic progression, unequivocal clinical progression, or death.
    PFS is defined as the time from randomization to the earliest objective evidence of radiographic progression, unequivocal clinical progression, or death on study, whichever occurs first.
    - Radiographic disease progression is defined for bone disease by the appearance of 2 or more new lesions on whole-body radionuclide bone scan per PCWG2 criteria or for soft tissue disease by RECIST 1.1;
    - Unequivocal clinical progression is defined as any of the following:
    - new onset cancer pain requiring chronic administration of opiate analgesic medication;
    - deterioration from prostate cancer of ECOG performance status score to 3 or higher;
    - initiation of cytotoxic chemotherapy or radiation therapy or surgical intervention due to complications of tumor progression. Radiotherapy for palliative management of symptoms due to prostate cancer will not be considered unequivocal clinical progression;
    - Death on study is defined as death within 112 days of treatment discontinuation without objective evidence of radiographic progression.
    E.5.1.1Timepoint(s) of evaluation of this end point
    Time from randomization to the earliest objective evidence of radiographic progression, unequivocal clinical progression, or death on study, whichever occurs first.

    E.5.2Secondary end point(s)
    - Time to PSA progression, defined as the time from randomization to the date of the first PSA value in Period 2 demonstrating progression (Period 2). The PSA progression date is defined as the date that a ≥ 25% increase and an absolute increase of ≥ 2 ng/mL above the nadir recorded in Period 2 is documented, which must be confirmed by a second consecutive value obtained at least 3 weeks later;
    - PSA response, defined as the percentage change in PSA from randomization to Week 13 (or earlier for those that discontinue therapy), as well as the maximum decline in PSA that occurs at any point after treatment;
    - Objective response rate, defined as the best overall radiographic response after randomization as per Investigator assessments of response for soft tissue disease per RECIST 1.1, in subjects who have a measurable tumor;
    - Time to pain progression, defined as the time to an increase of ≥ 30% from randomization in the mean of BPI-SF pain intensity item scores (items 3, 4, 5, and 6);
    - Time to opiate use for cancer-related pain, defined as the time to initiation of chronic administration of opiate analgesia;
    - Time to first SRE, defined as the time from randomization to radiation therapy or surgery to bone, pathologic bone fracture, spinal cord compression, or change of antineoplastic therapy to treat bone pain;
    - Quality of life, as assessed using FACT-P and EQ-5D-5L.
    Other Endpoints:
    - Cumulative dose of docetaxel.
    - Health resource use (hospitalization and duration thereof; number and types of visits to a health
    professional) in Period 1 and Period 2
    Exploratory Endpoints:

    response or progression and for identifying mechanisms of resistance.
    Safety Endpoints:
    - Safety in both Periods will be assessed by AEs, clinically significant changes in physical examination, vital signs, laboratory values, and ECGs.
    - Deaths, defined as deaths due to any cause, will be summarized descriptively.

    - Imaging is assessed every 12 weeks
    - Clinical endpoints will be assessed at each clinical visit (every 3 weeks during docetaxel dosing, every 12 weeks thereafter)
