Clinical trials

The European Union Clinical Trials Register allows you to search for protocol and results information on:
  • interventional clinical trials that are conducted in the European Union (EU) and the European Economic Area (EEA);
  • clinical trials conducted outside the EU / EEA that are linked to European paediatric-medicine development.
  • Learn   more about the EU Clinical Trials Register   including the source of the information and the legal basis.


    The EU Clinical Trials Register currently displays   42567   clinical trials with a EudraCT protocol, of which   7008   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 in adults and that are not part of an agreed PIP are not public in the EU CTR (refer to European Guidance 2008/C 168/02   Art. 3 par. 2 and   Commission Guideline 2012/C 302/03,   Art. 5) .

    Clinical Trials marked as "Trial now transitioned" were transitioned to the Clinical Trial Regulation 536/2014 and can be further followed in the Clinical Trial Information System

    Primary: Change From Baseline In The Cohen-Mansfield Agitation Inventory (CMAI) Total Score After 12 Weeks Of Brexpiprazole Treatment

    End point title
    Change From Baseline In The Cohen-Mansfield Agitation Inventory (CMAI) Total Score After 12 Weeks Of Brexpiprazole Treatment [1]
    End point description
    To compare the efficacy of 2 fixed doses (1 mg/day and 2 mg/day) of brexpiprazole with placebo in participants with agitation associated with dementia of the Alzheimer's type, by the assessment of CMAI after 12 weeks of treatment. The CMAI assesses the frequency of agitated behaviors in elderly persons, such as hitting, cursing, and restlessness. It consists of 29 items all rated on a 1 to 7 scale with 1 being the “best” rating and 7 being the “worst” rating. The minimum possible CMAI total score is 29, and the maximum possible CMAI total score is 203. A decrease in score indicates improvement in symptoms. To control the overall type I error at 0.05 level when making 2 comparisons of brexpiprazole doses versus placebo, statistical testing was carried out using a hierarchical testing procedure in the order of: 1) comparison of 2 mg/day brexpiprazole versus placebo, and 2) comparison of 1 mg/day brexpiprazole versus placebo.

Scores were: 0 = not assessed; 1 = normal, not at all ill; 2 = borderline mentally ill; 3 = mildly ill; 4 = moderately ill; 5 = markedly ill; 6 = severely ill; and 7 = among the most extremely ill participants.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    06 May 2013
    Amendment number 1: Based on FDA feedback, the randomization ratio was changed from 1:2:2:2 to 1:1:1:1 (brexpiprazole 0.5 mg/day, brexpiprazole 1 mg/day, brexpiprazole 2 mg/day, placebo, respectively). Actigraphy and eDiary assessments were added to the protocol along with description of the use of day passes in this trial.
    16 Dec 2013
    Amendment number 2: The second amendment changes were made on the basis of adjustments to facilitate appropriate trial implementation and communication. It served to reflect clarifications and additions to study procedures intended to enhance participant safety and accuracy of data. Revised items included increasing the number of participating sites and recruitment period, clarification on consenting requirements, clarification of certain inclusion/exclusion criteria, and updates to the prohibited medication list. The amendment also added the option for participants who completed the 331-12-283 (2013-000503-17) trial to enter the 331-13-211 (2014-000424-23) safety trial.
    07 Jul 2014
    Amendment number 3: The changes were made to address the potential issue of missing data due to participants terminating early, as well as on the basis of adjustments considered important to ensure the safety of the participants enrolled and to facilitate appropriate study implementation and communication. The 0.5-mg arm was removed, which resulted in a reduction to the number of participants randomized. Noninstitutionalized participants were included with revisions to criteria and assessments for participants in this setting. The RUD scale and Mortality Assessment at Week 16 for participants who discontinued the trial early were added.
    10 Sep 2015
    Amendment number 4: The changes reflect clarifications and changes to trial procedures intended to enhance participant safety and accuracy of data as well as streamline the inclusion/exclusion criteria. The number of trial sites, as well as participating countries, was increased. Actigraphy was removed and eDiary was replaced with paper diaries. Revisions were made to the Schedule of Assessments to decrease participant burden.
