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   43871   clinical trials with a EudraCT protocol, of which   7290   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 ).

    Recruitment
    Recruitment details
    Approximately 497 subjects (later increased to 540 subjects) were to be enrolled at approximately 20 study sites.

    Pre-assignment
    Screening details
    Subjects were selected from a population of stable healthy adults, at least 18 years of age, who had moderate (GLS score=2) or severe (GLS score =3) glabellar lines at maximum frown, as assessed by the Investigator on the 4-point photonumeric Glabellar Line Scale (GLS, 0=no lines, 1=mild, 2=moderate, 3=severe).

    Subject, Investigator
    Blinding implementation details
    To maintain blinding at the time of treatment on Day 0, at each study site, on a per subject basis, an appropriate on-site, protocol-trained designated individual – accessed an online tool, the Interactive Web Response System (IWRS), to obtain the kit number for that subject. The IWRS kit identification system ensured that the study randomization schedule at each site was maintained. Each study vial contained DWP-450, BOTOX or Placebo.

    Statistical analysis title
    Statistical Analysis Plan, Final Version 3.0, June
    Statistical analysis description
    Tests of superiority for DWP-450 versus Placebo and for OnabotulinumtoxinA versus Placebo for the primary endpoint were to be performed using the unconditional exact test, by inversion of two one-sided tests using standardized statistics [1]. Non-inferiority of DWP-450 versus OnabotulinumtoxinA for the primary endpoint was to be concluded if the lower bound of the two-sided 95% CI for the difference in the proportions of responders in each group was >-0.10 – i.e., >-10.0%.

    Notes
    [1] - Method : Fisher's exact test for superiority test, and two sided 95% confidence intervals for the non-inferiority evaluation (Wald asymptotic confidence intervals). Dispersion value : 3.25% for non-inferiority; for superiority 3.61%. Confidence interval : -1.9%, 10.8% for non-inferiority; for superiority 70.3%, 89.4%. Non-inferiority for DWP-450 vs OnabotulinumtoxinA; superiority for DWP-450 vs Placebo.
    [2] - P-value "< 0.001" is valid for superiority test [2]. A p-value <0.025 was required for each test to conclude that DWP-450 and OnabotulinumtoxinA were each superior to Placebo. Confidence interval, lower limit : -10%
