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   44339   clinical trials with a EudraCT protocol, of which   7369   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 compare the percentage of participants with steady state (Cycle 5) trough plasma concentration (Ctrough) >20 μg/mL for PF 05280014 versus trastuzumab-EU in patients with operable HER2-positive breast cancer who received study therapy together with Taxotere and carboplatin in the neoadjuvant setting.
    Protection of trial subjects
    This study was conducted in compliance with the ethical principles originating in or derived from the Declaration of Helsinki and in compliance with all International Conference on Harmonisation Good Clinical Practice Guidelines. In addition, all local regulatory requirements were followed, in particular, those affording greater protection to the safety of trial participants. A signed and dated informed consent was required before any screening procedures were done, with the exception of radiographic tumor assessments (which were performed as part of routine procedures within 6 weeks prior to randomization and in accordance with protocol method/documentation requirements). Appropriate documentation indicating that these radiographic tumor assessments were performed as standard of care were available in the patient’s source notes. The investigators explained the nature, purpose, and risks of the study to each participant. Each participant was informed that she could withdraw from the study at any time and for any reason. Each participant was given sufficient time to consider the implications of the study before deciding whether to participate.
    Background therapy
    		 Taxotere was administered every 3 weeks on Day 1 of each cycle. The starting dose of Taxotere was 75 mg/m2 administered IV over 60 minutes. Carboplatin was administered every 3 weeks on Day 1 of each cycle.

    Recruitment
    Recruitment details
    		 The study was initiated at 67 sites in 10 countries (across Europe and the United States [US]), of which 21 sites had no enrollment activity. Advertisements approved by ethics committees and investigator databases may be used as recruitment procedures. All advertisements must have been approved by the study Sponsor prior to use.

    Pre-assignment
    Screening details
    		 Informed consent must have been obtained before any study specific procedures were performed (with the exception of certain imaging assessments if meeting the protocol specified criteria); however, it may be obtained more than 28 days before randomization.

    The first administration of PF-05280014 on Day 1, Cycle 1 was a loading dose of 8 mg/kg infused over 90 minutes. The duration of infusion could be lengthened according to local standard of care or tolerability. Subsequent infusions followed every 3 weeks (ie, cycled every 21 days) with a dose of 6 mg/kg administered over 30 to 90 minutes depending on tolerability. In the absence of objective disease progression or prohibitive toxicity, patients received PF-05280014 for 6 cycles.
