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   44020   clinical trials with a EudraCT protocol, of which   7318   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
    The main objective of this study was to evaluate the efficacy and safety of YAZ (drospirenone 3 milligram [mg] / ethinylestradiol 20 microgram [mcg]) in comparison with placebo in Chinese female subjects with moderate acne vulgaris over 6 treatment cycles.
    Protection of trial subjects
    The conduct of this clinical study met all local legal and regulatory requirements. The study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and the International Conference on Harmonization guideline E6: Good Clinical Practice. Before entering the study, the informed consent form was read by and explained to all subjects and/or their legally authorized representative. Participating subjects signed informed consent form and could withdraw from the study at any time without any disadvantage and without having to provide a reason for this decision. Only investigators qualified by training and experience were selected as appropriate experts to investigate the study drug.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: All randomized subjects who took at least one tablet of study medication and who provided at least one observation after taking of the first tablet were included in the full analysis set and the baseline data was provided for those subjects. Hence, the worldwide number of subjects enrolled in the trial differs from the number of subjects with data reported for the baseline period.

    End point description
    Acne lesions were counted by the trained designee over the entire face. All types of lesions were to be identified and separately counted, that is (i.e.), non-inflammatory open and closed comedones, and inflammatory papules, pustules, and nodules. The percent change from Cycle 6 to Baseline was calculated as (total lesion count at Baseline - total lesion count at Cycle 6)/(total lesion count at Baseline)*100, so that improvement is indicated by a larger percent change.

    		 Percent Change from Cycle 6 to Baseline in Lesion Count of Open Comedones
    End point description
    Acne lesions were counted by the trained designee over the entire face. All open comedones were to be identified and separately counted. The percent change from Cycle 6 to Baseline was calculated as (open comedone count at Baseline -open comedone count at Cycle 6)/(open comedone count at Baseline)*100, so that improvement is indicated by a larger percent change.

    The proportion of subjects rated as “improved” comprises those with complete remission, excellent, marked, or moderate improvement according to the Investigator’s Overall Improvement Rating and those with excellent, good, or fair improvement the Subject's Overall Self-Assessment Rating. No improvement or deterioration (worsening of disease signs and symptoms compared to Baseline in the view of investigator/subject) comprise "not improved" status.
