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   43871   clinical trials with a EudraCT protocol, of which   7290   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.

    		 Time to Onset of Confirmed Disability Progression (CDP) for at Least 12 and 24 Weeks During the Double Blind Treatment Period
    End point description
    Disability progression was defined as an increase in the EDSS score of: A) >=1.0 point from the baseline EDSS score when the baseline score was less than or equal to (<=) 5.5 B) >=0.5 point from the baseline EDSS score when the baseline score was >5.5 This endpoint was considered confirmatory only when results of both studies WA21092 and WA21093 were combined. Disability progression was considered confirmed when the increase in the EDSS was confirmed at a regularly scheduled visit at least 12 weeks or 24 weeks after the initial documentation of neurological worsening. ITT population included all randomised subjects in the study. Here, 99999 indicates median and -99999 and 99999 minimum and maximum of full range as less than 50% of subjects experience onset of CDP.

    		 Change From Baseline in Multiple Sclerosis Functional Composite (MSFC) Score to Week 96
    End point description
    MSFC score consists of: A) Timed 25-Foot walk; B) 9-Hole Peg Test (9-HPT); and C) Paced Auditory Serial Addition Test (PASAT-3 version). The MSFCS is based on the concept that scores for these three dimensions⎯ (arm, leg, and cognitive function) are combined to create a single score (the MSFC) that can be used to detect change over time in a group of subjects with MS. Since the three primary measures differ in what they actually measure, a common composite score for the three different measures i.e., Z-score was selected for the purpose. MSFC Score = {Z arm, average + Z leg, average + Z cognitive} / 3.0. The results from each of these three tests are transformed into Z-scores and averaged to yield a composite score for each subject at each time point. ITT population included all randomised subjects in the study. Here, n signifies the number of subjects evaluable at specified time points.

    		 Percent Change in Brain Volume as Detected by Brain Magnetic Resonance Imaging (MRI) From Week 24 to Week 96
    End point description
    Brain volume was recorded as an absolute “normalised” value at the baseline visit then recorded at subsequent visits as a percentage change relative to the absolute value at the baseline visit. Therefore, brain volume at Week 24 was calculated as the brain volume at the baseline visit multiplied by 1 + ([percentage change in brain volume from baseline visit to Week 24]/100). Estimates are from analysis based on mixed-effect model of repeated measures (MMRM) using unstructured covariance matrix: Percentage Change = Brain Volume at Week 24 + Geographical Region (US vs. ROW) + Baseline EDSS (< 4.0 vs. >= 4.0) + Week + Treatment + Treatment*Week (repeated values over Week) + Brain Volume at Week 24*Week. ITT population included all randomised subjects in the study. Here, number of subjects analysed signifies number of subjects who were evaluable for the endpoint.

    End point description
    The SF-36 is a multi-purpose, short-form health survey with 36 questions. It yields an 8-scale profile of functional health and well-being scores (domains) as well as psychometrically based physical and mental health summary measures. The SF-36 taps 8 health concepts: physical functioning, bodily pain, physical role functioning, emotional role functioning, emotional well-being, social functioning, vitality, and general health perceptions. The 8 scales are further summarized to 2 distinct higher-ordered clusters: the PCS and mental composite t-score (MCS). The range for all 8 domains as well as for the composite t-scores is from 0 to 100 with 100 as best possible health status and 0 as worst health status. Descriptive statistics at baseline include subjects with assessment at baseline and at least one post-baseline value. ITT population. Here, n signifies the number of subjects evaluable at specified time points.

    15 Jun 2012
    1. Dosing preparation and infusion guidance were revised to simplify the preparation of infusion bags and dosing procedures. 2. Specific eligibility cut-off values for immunoglobulin M (IgM) and immunoglobulin G (IgG) and the re-treatment criteria for IgG were modified to reflect the central lab reference ranges. 3. Sites were informed of additional, optional sub-studies conducted at select centers in which subjects could be eligible to participate
    28 Mar 2013
    1. Inclusion of an OLE phase under the same protocol. 2. Addition of the following exploratory objectives: proportion of disease activity free subjects, defined as absence of both relapses and sustained accumulation of disability, and absence of MRI activity by Week 96; evaluation of long term safety and efficacy of ocrelizumab in the OLE study phase. 3. Clarification on how sustained disability progression was calculated
    04 Sep 2014
    1. An update to the Statistical Considerations and Analytical Plan section of the protocol in line with the SAP amendment to implement European Medicines Agency (EMA) Scientific Advice and to increase statistical rigor. 2. Conversion of the optional investigator-sponsored Roche-supported exploratory substudies to Roche-sponsored studies as per current policy of the sponsor 3.
