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 ).  
     
    Examples: Cancer AND drug name. Pneumonia AND sponsor name.

    General information about the trial
    Main objective of the trial
    To Evaluate the efficacy of PM060184 in terms of progression-free survival at 4 months (PFS4) in third or fourth line setting in the subset population of advanced, hormone receptor positive, human epidermal growth factor receptor 2 (HER2) negative, breast carcinoma
    Protection of trial subjects
    The study was in compliance with ethical principles derived from the Declaration of Helsinki and the International Conference on Harmonization (ICH) Good Clinical Practice (GCP) guidelines. All the local requirements pertinent to safety of trial subjects were also followed during the conduct of the trial.
    Background therapy
    Primary antiemetic prophylaxis was compulsory prior to all PM060184 administrations. Standard treatment, according to ASCO guidelines, was administered: - 5-HT3 antagonists (ondansetron 8 mg or equivalent). - Steroids (dexamethasone 8 mg or equivalent). - Both oral and i.v. formulations were allowed, following the local institutional standards. If necessary, additional and/or extended antiemetic treatment could be considered (according to the Investigators’ standard practice).

    Recruitment
    Recruitment details
    At cutoff date, 22 patients had been included in the 1st stage: 21 were treated and evaluable for safety, and 18 were evaluable for the primary efficacy endpoint (PFS4). Patients enrollment between 12Feb2016 and 30Oct2017 (date of last F-Up, clinical cutoff) and corresponds to the 1st stage. All the patients were enrolled at 5 sites in Spain.

    The only drug administered and evaluated was PM060184, which was administered i.v. via a central line or a peripheral venous catheter (in 5 or 1-min administrations) at a dose of 9.3 mg/m2 on Day 1 and Day 8 every three weeks (q3wk) (three weeks = one treatment cycle). The drug substance PM060184-CD is a mixture of PM060184 and 2-hydroxypropyl-β-cyclodextrin. PM060184 drug product (DP) is provided as a sterile lyophilized powder for concentrate for solution for infusion with a strength of 15 mg of the active moiety PM060184. Before use, the vials should be reconstituted with 6 mL of water for injection to give a solution containing 2.5 mg/mL of PM060184. PM060184 as 15-mg DP was developed for i.v. administration. Prior to administration, the reconstituted vials were further diluted with a dextrose 5% solution for infusion. Each 15-mg vial of PM060184 was a single-use vial. The diluted solution should be protected from light exposure.

    Notes
    [1] - No statistical analyses have been specified for this primary end point. It is expected there is at least one statistical analysis for each primary end point.
    Justification: The threshold for proving antitumor activity (at least nine patients reaching PFS4) was not reached, the primary endpoint was unmet, and the study was closed without recruiting more patients in the first stage and without opening the second stage.
