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   43800   clinical trials with a EudraCT protocol, of which   7272   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.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    PSP is a sporadic neurodegenerative disorder resulting in a Parkinson syndrome with postural instability, oculomotor deficits, and cognitive decline. With an average annual incidence of 5.3 / 100000 and an age-adjusted prevalence of 6.4 / 100000, PSP is as common as motor-neuron disease. The progression of PSP is rapid and the median survival after onset of symptoms is 5-10 years. Presently, there is no known effective symptomatic or neuroprotective therapy for PSP.
    MedDRA Classification
    E.1.3Condition being studied is a rare disease Yes
    E.2 Objective of the trial

    E.5 End points
    E.5.1Primary end point(s)
    The primary goal of this study is to investigate whether the amount of adenosine-diphosphate in cells of the frontal cortex and putamen differ between PSP patients and healthy controls. The problem will be formulated statistically as a two-sided test of the hypothesis (H0: “Equal distribution of the the amount of adenosine-diphosphate in cells of the frontal cortex and putamen in the two groups”). Due to the small sample size the Wilcoxon-Mann-Whitney-test will be used. The significance level is set to α = 0.05.

    Intent-to-treat (ITT) population All PSP patients randomized.
    Per-protocol (PP) population All PSP patients of the ITT population with completed treatment according to the study plan and no major protocol violations.
    Safety (S) population All PSP patients randomized who received at least one administration of study medication.
    MRS population All PSP patients and healthy control subjects having undergone baseline MRS assessment.
    The test of the primary endpoint (i.e test of H0) will be applied to the MRS population. To examine the robustness of its result, a further test in the FS population with appropriate imputation of missing values will be done.

    In order to obtain evidence for the assumed pathophysiological mechanisms (cf. 2.2), descriptive statistics (mean, median, standard deviation, range, quantiles and 95% confidence intervals) for the parameters measured by MR spectroscopy (total amounts of ATP, ADP, pCre, tCre, Lac, ratio of ADP to ATP, ratio of pCre to tCre; cf 3.2) will be given for the baseline values in the subgroup of non-PSP subjects and the subgroup of PSP patients. These analyses will be done for the MRS population.

    To obtain evidence for the effect of CoQ10 on these mechanisms descriptive statistics for differences from baseline to the 6 weeks visit in the aforementioned parameters will be given for the subgroup of PSP patients for each treatment group (CoQ10 and placebo). These analyses will be done for the ITT population and for the PP population in order to examine the robustness of results.

    Analysis of all secondary endpoints takes place exploratively and descriptively. For categorical variables, the number and proportion of patients in each category will be given. For continuous variables, the number of patients, mean, standard deviation, quartiles, range and 95% confidence intervals will be provided. The data will be summarized for all patients as well as for each of the randomized treatment groups

    Analysis of safety takes place for the S population.

    The General Practitioners will be informed about the end of the study and asked to follow the patients. Should any indication for an AE arise within the 3 months following the termination of the study, the General Practitioner will immediately inform the Principal Investigator. It is the responsibility of the Principal Investigator to initiate immediately the necessary medical measures.
