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   43857   clinical trials with a EudraCT protocol, of which   7284   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
    Primary objective was to assess the severity of flu like symptoms (FLS), as measured by Items 13 to 16 of the Multiple Sclerosis Treatment Concern Questionnaire (MSTCQ), in subjects injecting Rebif 44 mcg in the morning versus the evening.
    Protection of trial subjects
    Subject protection was ensured by following high medical and ethical standards in accordance with the principles laid down in the Declaration of Helsinki, and that are consistent with Good Clinical Practice and applicable regulations.

    		 Difference in Multiple Sclerosis Treatment Concern Questionnaire (MSTCQ) Flu Like Symptom (FLS) Score Between Rebif Morning Administration and Rebif Evening Administration Groups at Week 12
    End point description
    The MSTCQ was used as a tool to measure treatment satisfaction, focusing on the attributes specific to multiple sclerosis (MS) medications. The FLS subscale of MSTCQ was defined as the sum of the scores for questions 13 to 16 with a minimum possible total FLS score = 1 and a maximum possible total FLS score = 20. Lower score indicates lower flu like symptoms and better satisfaction. Difference between Rebif Morning Administration and Rebif Evening Administration groups at Week 12 is presented in statistical analysis section. The Intention to Treat Analysis Set (ITT) included all subjects enrolled into the study and assigned to the RebiSmart device. Here, "Number of Subjects Analyzed" signifies those subjects who were evaluable for this outcome measure. Missing data on FLS were imputed using the last observation carried forward (LOCF) method.

    End point description
    MSTCQ: a tool to measure treatment satisfaction, focusing on attributes specific to MS medications. Following sub-scales were assessed: Injection site reactions (ISRs), Global side-effects, Benefits, Pain, Visual Analog Scale (VAS), and Rating of Pain. ISR subscale: defined as sum of scores for questions 17 to 20 (minimum score 4 and maximum score of 20). Global side-effects subscale: defined as sum of scores for questions 21 to 23 (minimum score 3 and maximum score 15). Benefits (question 35); description of pain (question 36); VAS (question 37); rating of pain (question 38) subscales ranged from 1 to 5, with minimum score of 1 and maximum score of 5. For each of subscales, lower scores indicated better satisfaction. ITT population was used. "Number of Subjects Analyzed" = subjects who were evaluable for this outcome measure and "n" = subjects who were evaluable for this outcome measure for specified category.

    HADS was used to measure depression and anxiety in subjects. The scale was limited to 14 questions. Seven of the items related to anxiety and 7 related to depression. Each item on the questionnaire was scored from 0-3 giving a total score between 0 and 21 for either anxiety or depression where higher score indicates more anxiety/depression. The ITT included all subjects enrolled into the study and assigned to the RebiSmart device. Here, "Number of Subjects Analyzed" signifies those subjects who were evaluable for this outcome measure.

    PSQI is a self-rated questionnaire which assess sleep quality and disturbances over a 1-month interval using seven clinically derived components of sleep difficulties: sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medications, and daytime dysfunction. PSQI is a summary of 7 components. Each component is scored from 0 to 3, therefore PSQI has a range of 0 (better) to 21 (worse). Interpretation of the PSQI is that a score less than 5 is associated with good sleep quality and a score of 5 or greater is associated with poor sleep quality. The ITT included all subjects enrolled into the study and assigned to the RebiSmart device. Here, "Number of Subjects Analyzed" signifies those subjects who were evaluable for this outcome measure.

    MusiQoL: validated 31-item questionnaire describing 9 dimensions: activities of daily living; psychological well-being; symptoms; relationships with friends; relationships with family; relationship with healthcare system; sentimental and sexual life; coping; and rejection. Each of questions was answered using a 6-point Likert scale ranging from 1 (never/not at all) to 6 (always/very much). Scores of each dimension were obtained by computing mean of item scores of dimension with negatively worded item scores reversed so that higher scores indicated higher health-related quality of life (QoL). All 9 dimension scores were linearly transformed to 0 to 100 scale and average of 9 dimensions was used to give a Global Score ranging from 0 to 100 (higher scores indicated higher health-related QoL. ITT population was used. "Number of Subjects Analyzed" = subjects who were evaluable for this outcome measure and "n" = subjects who were evaluable for this outcome measure for specified category.

    		 Correlation Between Change From Baseline in Circulating Levels of Cytokines and in Flu Like Symptom (FLS) Score at Week 12
    End point description
    Correlation was assessed by using Pearson correlation coefficient. The MSTCQ was used as a tool to measure treatment satisfaction, focusing on the attributes specific to MS medications. The FLS subscale of MSTCQ was defined as the sum of the scores for questions 13 to 16 with a minimum possible total FLS score = 1 and a maximum possible total FLS score = 20. Lower score indicates lower flu like symptoms and better satisfaction. The ITT included all subjects enrolled into the study and assigned to the RebiSmart device. Here, "Number of Subjects Analyzed" signifies those subjects who were evaluable for this outcome measure.

    End point description
    An adverse event (AE) was defined as any untoward medical occurrence in a subject which does not necessarily have a causal relationship with the treatment. An AE was any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with use of a medicinal product, whether or not considered related to the medicinal product. A serious adverse event (SAE) was an AE that resulted in any of the following outcomes: death; life threatening; persistent/significant disability/incapacity; initial or prolonged inpatient hospitalization; congenital anomaly/birth defect or was otherwise considered medically important. The term TEAE is defined as AEs starting or worsening after the first intake of the study drug. The Safety Analysis Set (SAF) included all subjects in the ITT who received at least 1 dose of the planned study treatment.
