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   37736   clinical trials with a EudraCT protocol, of which   6184   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.

    * Subject may have 1 course of palliative radiation or surgical therapy to treat symptoms resulting from metastatic disease if it was administered at least 4 weeks prior to day 1;
    *Up to 6 cycles of docetaxel therapy with final treatment administration completed within 2 months of day 1 and no evidence of disease progression during or after the completion of docetaxel therapy;
    *Up to 6 months of ADT with LHRH agonists or antagonists or orchiectomy with or without concurrent antiandrogens prior to day 1 if subject was treated with docetaxel, with no radiographic evidence of disease progression or rising PSA levels prior to day 1;
    *Prior ADT given for < 36 months in duration and > 9 months before randomization as neoadjuvant/adjuvant therapy.

    - Subject received treatment with 5-α reductase inhibitors (finasteride, dutasteride) within 4 weeks prior to day 1.

    - Subject received treatment with herbal medications that have known hormonal antiprostate cancer activity and/or are known to decrease PSA levels within 4 weeks prior to day 1.

    - Subject received prior aminoglutethimide, ketoconazole, abiraterone acetate or enzalutamide for the treatment of prostate cancer or participation in a clinical study of an investigational agent that inhibits the androgen receptor or androgen synthesis (e.g., TAK-700, ARN-509, ODM-201).

    - Subject received bisphosphonates or denosumab withtin 2 weeks prior to day 1 unless administered at stable dose or to treat diagnosed osteoporosis.

    - Subject has shown a hypersensitivity reaction to the active pharmaceutical ingredient or any of the study capsule components, including Labrasol®, butylated hydroxyanisole (BHA), and butylated hydroxytoluene (BHT).
