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   44334   clinical trials with a EudraCT protocol, of which   7366   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.

The score and description indicated as follows: -2= left side of the face much better than right side, -1= left side of the face better than right side, 0= no clinical difference between the right and left sides of the face, 1= right side of the face better than the left side, 2= right side of the face much better than the left side. This analysis was performed on ITT population. ITT population included all subjects who were randomized. Here ‘N’ (number of subjects analyzed) signifies subjects who were evaluable for this endpoint.

    		 Number of Subjects With Adverse Events (AEs)
    End point description
    AE was any untoward medical occurrence in a subject or clinical investigation subject administered a pharmaceutical product and which does not necessarily had a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory value), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. This analysis was performed on safety population. Safety population included subjects in the ITT population who received at least 1 application of the investigational product. Number of subjects with AE's were reported.

    		 Number of Subjects Reported Worst Local Tolerability Score on Treated Areas (Face and Ear) From Day 1 to Follow up (Week 7)
    End point description
    Signs and symptoms of local cutaneous irritation(local tolerability [erythema, scaling, dryness, stinging/burning, pruritus]) were evaluated on all treated areas (face and behind ears if applicable) every day from Day 1 up to follow-up (Week 7) using a 4-point scale of None (0), Mild (1), Moderate (2), or Severe (3). Safety population included subjects in the ITT population who received at least 1 application of the investigational product. Number of subjects reported worst local tolerability score on treated areas from Day 1 to follow up (Week 7) was reported. Here 'n' (number analyzed) signifies number of subjects who were evaluable for each specified category.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    22 Sep 2016
    Amendment 1: - Modified the primary efficacy endpoint to evaluate only inflammatory acne lesion count at Day 40 per half face and not percent reduction - Changed “inflammatory lesion count and percent reduction per half face (at each evaluation visit)” from primary to secondary efficacy criteria - Created a last visit for treatment period (Endpoint), which contained the last observation carried forward (LOCF). The ITT population was to be analyzed for efficacy only at Baseline and at Day 40 (Endpoint/LOCF) - Added that all safety data would be summarized based on the Safety population - Revised the description of inferential statistical analyses to: This is an exploratory Phase 2a study used to inform sponsor for an internal go/no decision. Primary endpoint is inflammatory acne lesion count at Day 40 per half face on ITT-LOCF population. Significance would be declared for 2-sided tests when the p-value did not exceed 0.05 - The others endpoints were exploratory. P-values were to be given for indicative purpose so no adjustment was to be made -Changed confidence interval from 90% to 95% - Corrected country code for study numbers of studies used for historical data with respect to sample size determination
