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   43841   clinical trials with a EudraCT protocol, of which   7281   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
    ♦ Histologically confirmed diagnosis of prostate adenocarcinoma
    ♦ Asymptomatic or mildly symptomatic (defined as short form question #3 in Brief Pain Inventory worst pain must be < 4.
    ♦ Metastatic to bone with ≥ 4 bone metastases (ambiguous areas of increased uptake on 99mTC Bone Scan (BS) should be confirmed by CT or MRI) with or without additional lymph node metastases. Patients with visceral metastases are not allowed. Patients with multifocal bone lesions are allowed, while patients with diffuse confluent bone lesions (superscan) are not allowed in the trial.
    Note: Patients must start treatment with a bone protecting agent (at doses used to reduce the incidence of skeletal related events) ideally before or at the time of randomization, if patient is not already on one. A minimum of two doses is recommended before the first administration of Ra223 in the experimental arm. The first administration of Ra223 should be scheduled at least 6 weeks after the first administration of bone protecting agent.
    Note: For French sites only, patients must not have undergone a PET/CT scan for restaging prostate cancer using radiopharmaceuticals such as 18F-FDG, 18F-fluoride, 18F-Fluorocholine or a PSMA (prostate-specific membrane antigen) ligand or any other tracer.
    ♦ Progressive CRPC according to Prostate Cancer Working Group 3 (PCWG3) i.e. either:
    -For patients who manifest disease progression solely as a rising PSA level, PCWG3 criteria require documentation of a sequence of rising PSA values at a minimum of 1-week intervals with the last value ≥ 2 ng/mL.
    -For patients with disease progression manifest in the bone, irrespective of progression by rising PSA, PCWG3 guidelines require appearance of 2 or more new lesions. Ambiguous results should be confirmed by other imaging modalities than bone scan (e.g.: CT-scan or MRI).
    -For patients with disease progression manifest at nodal sites, irrespective of progression by rising PSA, PCWG3 requires progression according to RECIST 1.1.
    ♦ Ongoing androgen deprivation therapy (ADT) with luteinizing hormone-releasing hormone (LHRH) agonist or antagonist or bilateral orchiectomy.
    Patients must be at least 18 years old

    Note: patients having received docetaxel for CRPC are excluded.
    ♦ Prior use of abiraterone is permitted if the patient had a response or stable disease on abiraterone for a minimum of 1 year for metastatic castration sensitive prostate cancer
    Note: patients having received abiraterone for CRPC are excluded.
    ♦ Prior treatment with abiraterone is allowed if it was stopped at least 4 weeks prior to randomization.
    ♦ Previous treatment with bicalutamide, or flutamide is allowed if it was stopped at least 48 hours prior to randomization.

    ♦ Drugs known to lower the seizure threshold or prolong QT interval are not permitted.
    ♦ Participants who have pregnant partners must use a condom and those with partners of childbearing potential must use a condom and another adequate birth control measures if engaging in sexual activities during the study treatment period and for at least 3 months after last dose of enzalutamide and 6 months after the last dose of Ra223. A highly effective method of birth control is defined as those which result in low failure rate (i.e. less than 1% per year) when used consistently and correctly.
    ♦ Absence of any psychological, familial, sociological or geographical condition potentially hampering compliance with the study protocol and follow-up schedule; those conditions should be discussed with the patient before registration in the trial.
