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   43865   clinical trials with a EudraCT protocol, of which   7286   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 ).

    End point description
    Combined counts of AEs of FLS, ISRs and ISR-P were reported. FLS included chills, pyrexia, myalgia, and asthenia. ISR is defined as a post-application assessment score ≥2 in subject and clinician assessments using Patient's Erythema Self-Assessment 1 (PSA) and Clinician Erythema Assessment (CEA) scales respectively. PSA assesses erythema severity (skin redness) on 5-point scale where 0=clear of unwanted redness and 4=completely unacceptable redness. CEA evaluated subject`s erythema severity on 5-point scale where 0=clear skin with no signs of erythema and 4=severe erythema/fiery redness. ISR-P is defined as a visual analog scale (VAS) associated with ISR ≥1 immediately after injection/30 minutes post-injection. Safety population included all the subjects who received at least one dose of the study treatment. Number of subjects analysed=subjects with AEs of FLS, ISRs and ISR-P over 24 weeks of treatment.

    Change in Subject-reported Treatment Satisfaction Using the Treatment Satisfaction Questionnaire for Medication (TSQM-9) From Baseline to Week 24 in Subjects Treated With Plegridy Versus Current SC IFN-β
    End point description
    TSQM is a 14-item instrument consisting of four scales: Effectiveness scale (questions 1 to 3), side effects scale (questions 4 to 8), convenience scale (questions 9 to 11) and overall satisfaction scale (questions 12 to 14). In TSQM-9, the five items related to side effects of medication were not included. The scores were computed by adding items for each domain. The lowest possible score was subtracted from this composite score and divided by the greatest possible score minus the lowest possible score. This provided a transformed score between 0 and 1 that was then multiplied by 100. TSQM-9 domain scores range from 0 to 100 with higher scores representing higher satisfaction on that domain. Efficacy population included all enrolled subjects who had at least one post-baseline efficacy assessment. Number of subjects analysed=number of subjects with available data for analysis. Number analysed (n) signifies number of subjects analysed for the specified measurement.

    End point description
    The EQ-5D-3L is a standardised instrument for use as a measure of health outcome. It is a health questionnaire that consists of the EQ-5D descriptive system and the EQ VAS. The descriptive system consists of 5 dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), each dimension has 3 severity levels: No problems, some or moderate problems, extreme problems. The EQ-VAS records the respondent’s self-rated health on a VAS ranging from 0 (worst imaginable health state) to 100 (best imaginable health state). The index score is transformed into a utility score between 0 (worst health state) and 1 (best health state). Higher scores indicate good health. Negative change from baseline indicates deteriorated health. Efficacy Population included all enrolled subjects who had at least one post-baseline efficacy assessment. Number of subjects analysed=number of subjects with available data for analysis.

    End point description
    The WPAI questionnaire is a validated instrument to measure impairments in work and activities. The WPAI yields four types of scores: Absenteeism (percent work time missed), presenteeism (percent impairment at work/ reduced on-the-job effectiveness), work productivity loss (percent overall work impairment/absenteeism plus presenteeism), and activity impairment (percent) over the previous 7 days.

The total score was obtained summing the number given at each item and it ranges from 9 (less fatigue) to 63 (greater fatigue severity). The mean of all the scores is calculated and reported in this endpoint ranging from 1 (less fatigue) to 7 (greater fatigue severity). Positive change from baseline indicates greater fatigue. Efficacy population included all enrolled subjects who had at least one post-baseline efficacy assessment. Number of subjects analysed=number of subjects with available data for analysis.

    Change in PRO Measure: HADS Score From Week 24 Through 72 in Subjects Continuously Treated With Plegridy Versus Subjects Who Switched From Current SC IFN-β Therapy to Plegridy at the End of the Comparator Period
    End point description
    The HADS is a self-rating scale that measures anxiety and depression in both hospital and community settings. Responses are based on the relative frequency of symptoms over the past week, recorded on a four-point Likert scale ranging from 0 (not at all) to 3 (very often indeed). Responses are summed to provide separate scores for anxiety and depression symptomology; Each of anxiety or depression scale has a score range of 0-21. Higher scores indicate severe symptoms (higher levels of anxiety and depression). Negative change from baseline indicates improved symptoms (less anxiety and depression). Efficacy population included all enrolled subjects who had at least one post-baseline efficacy assessment. Number of subjects analysed=number of subjects with available data for analysis. Number analysed (n) signifies number of subjects analysed for the specified measurement.

    An AE is any untoward medical occurrence in a subject or clinical investigation subject administered a pharmaceutical product and that does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product. An SAE is any untoward medical occurrence that at any dose, results in death; in the view of the investigator places the subject at immediate risk of death; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; results in a congenital anomaly/birth defect; is a medically important event.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    27 Feb 2018
    Removed the following from the list of required evaluations at Baseline Visit: Hematology; Blood chemistry (including thyroid function tests); Coagulation study; Urinalysis (including a urine pregnancy test for female subjects). • Removed “bicarbonate "from the list of laboratory safety assessments.
    12 Jun 2018
    Updated the reference of McDonald criteria (Polman 2011) to 2017.
    22 Oct 2019
    • Replaced ‘current treatment’ with ‘PLEGRIDY™’. • Removed: for subjects who switch IFN β treatment to PLEGRIDY™ treatment at Week 24 in study visits. • Added text to sample size justification: Due to the small sample sizes of 37 & 38 in each group, primary endpoint of combined counts of narrow FLS and ISR events was presented in descriptive manner. • Removed:“2-sided 95% CIs for difference in means of combined counts of FLS and ISR/ISR-P events/subject over total study time of 24weeks of current SC IFN-β arm & PLEGRIDY™ every-2-weeks arm was provided. • If distribution of events did not follow normal distribution, Mann-Whitney test was used to test difference in combined counts of FLS & ISR/ISR-P events/subject for24 weeks between current SC IFN-β arm and PLEGRIDY™ every-2-weeks arm. • If over dispersion of data occurs, Poisson regression model and/or negative binomial model adjusted for certain demographic, baseline disease characteristics of interest was used to compare event rate between current SC IFN-β arm & PLEGRIDY™ every-2-weeks arm” from primary endpoint analysis. • Removed: ”A t- test will be used to assess difference in means for current SC IFN-β arm & PLEGRIDY™ every-2-weeks arm. • For independent comparative analyses at 24 weeks for categorical additional endpoints, chi- square test/Fisher exact/2-sample proportion test was used to assess the distribution difference in these secondary endpoints between the current SC IFN-β arm & PLEGRIDY™ every-2-weeks arm. • For paired comparative analyses between 24, 48 weeks as well as 24 weeks and end of study for these additional endpoints, a paired t-test/Wilcoxon/a signed rank test was applied to compare continuous endpoints within same treatment arm at different time frames; McNemar test may be used to compare change of categories for those categorical endpoints within same treatment arm at different time frames” from additional endpoints analysis.
