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   43861   clinical trials with a EudraCT protocol, of which   7284   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 ).

    General information about the trial
    Main objective of the trial
    Part A: To assess the safety and tolerability (incidence and severity of adverse events [AEs]) of the combination of onalespib (AT13387) and abiraterone acetate and to select the most promising treatment regimen for the combination in subjects with castration-resistant prostate cancer (CRPC) who are no longer responding to treatment with abiraterone acetate alone, based on the overall assessment of safety and antitumor activity. Part B: To assess and compare the antitumor activity (response rate per the Prostate Cancer Working Group 2 [PCWG2] recommendations) between single-agent AT13387 and the combination of AT13387 and abiraterone acetate in subjects who are no longer responding to treatment with abiraterone acetate alone. Part A of the study was completed; however, Part B was not performed.
    Protection of trial subjects
    The study was conducted in accordance with the International Conference on Harmonisation (ICH) Good Clinical Practice (GCP) guidelines; the US 21 Code of Federal Regulations (CFR) Parts 11, 50, 54, 56, and 312; any other applicable local regulatory requirements; and the principles enunciated in the Declaration of Helsinki. The ICF(s) used for each study centre complied with the Declaration of Helsinki, federal regulations (US 21 CFR Part 50 and other national requirements), and ICH GCP guidelines and was approved by the sponsor and the investigator's IRB/IEC. The investigator, or a person delegated by the investigator, explained the medical aspects of the study, including the nature of the study and the treatment, its purpose, the procedures involved, and the potential benefits and risks. After having been informed that participation was voluntary and that subjects may withdraw from the study at any time, without prejudice, each subject signed the IRB/IEC-approved ICF prior to undergoing any study specific procedures and enrollment in the study.
    Background therapy
    Subjects were randomised to receive 1 of 2 different regimens of onalespib in combination with abiraterone acetate 1000 mg orally (PO) once daily and prednisone or prednisolone 5 mg PO twice daily.

    Recruitment
    Recruitment details
    A total of 22 principal investigators at 33 study centres (21 in the US, 10 in the UK, 1 in Canada, and 1 in Spain) enrolled subjects in this study. The first subject was dosed with onalespib on 09 January 2013 and the last subject completed dosing on 17 July 2014.

    Pre-assignment
    Screening details
    A total of 90 subjects were screened for enrolment in the study. Of these, 41 were screen failures, 49 were enrolled, and 48 were treated. A subject who was randomised but not treated was excluded from the summary statistics.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: One subject was enrolled but not treated; therefore this subject was not included in summary statistics for the study.
