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   43865   clinical trials with a EudraCT protocol, of which   7286   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
    To evaluate the efficacy of pamiparib in patients with metastatic castration-resistant prostate cancer (mCRPC) positive for circulating tumor cells (CTC) with homologous recombination deficiency (CTC-HRD-positive; per Epic Sciences assay), as per Prostate Cancer Clinical Trials Working Group [PCWG3] criteria.
    Protection of trial subjects
    This trial was designed and monitored in accordance with Sponsor procedures, which comply with the ethical principles of GCP as required by the major regulatory authorities, and in accordance with the Declaration of Helsinki. The IEC/IRB-approved ICF was signed and dated by the subject or the subject’s legally authorized representative before his or her participation in the study. A copy of each signed ICF was provided to the subject or the subject’s legally authorized representative. All signed and dated ICFs were retained in each patient’s study file or in the site file. For any updated or revised ICFs, written informed consent was obtained using the IEC/IRB-approved updated/revised ICFs for continued participation in the study.

    Objective Response Rate (ORR) Determined by Independent Central Review [1]
    End point description
    ORR is the percentage of participants with a best objective response of complete response (CR) or partial response (PR) confirmed at a subsequent timepoint ≥ 4 weeks later by an Independent Review Committee (IRC). Efficacy-Evaluable Analysis Set: includes all participants in the Safety Analysis Set who had measurable disease at baseline and at least 1 post-baseline tumor assessment, unless they permanently discontinue pamiparib or the study early due to clinical progression or death before tumor assessment. Participants with available data were included in the analysis.
