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.

    General information about the trial
    Main objective of the trial
    The purpose of this study is to characterize the safety, efficacy and dose response of BMS-945429 in subjects with active Psoriatic Arthritis and an inadequate response to NSAIDs and non-biologic DMARDs
    Protection of trial subjects
    Standard of care procedures were employed in order to minimize harm to the patients. Study staff continuously interacted with the patients and were thoroughly trained on patient rights as well as medically trained to handle any adverse events. Study staff were well-informed on procedures to handle subjects from pre-screening through the completion of the study. All patients were explained the alternatives to being a part of the study. Procedures were also in place to ensure there was no undue coercion during the informed consent process.

    Percent of Participants Achieving Psoriasis Area Severity Index (PASI) 75 Response Rate
    End point description
    To calculate the PASI score, the psoriasis plaques found on each body region are graded for their combined redness, thickness, and scaliness. The severity of the plaques in each region is graded on a 0 to 4 scale, with 0 meaning no involvement and 4 meaning severe involvement. Next, the amount of surface area on each body region that is covered by the plaques is calculated. The total surface area affected by psoriasis is graded from 0 to 6, with 0 meaning no involvement and 6 meaning greater than 90 percent of the region covered in plaques. These grades are then fed into an equation to determine the patient's PASI score. The PASI score then is used as a clinical assessment of the patient's psoriasis involvement. A person free of psoriasis has a score of 0 and the score could be as high as 72. PASI 75 means that the person's PASI score dropped by 75 percent as a result of the psoriasis treatment.

    Percent of Participants Achieving a Health Assessment Questionnaire (HAQ) Response
    End point description
    For each item, there is a four-level difficulty scale that is scored from 0 to 3, representing normal (no difficulty) (0), some difficulty (1), much difficulty (2), and unable to do (3). There are 20 questions in eight categories of functioning - dressing, rising, eating, walking, hygiene, reach, grip, and usual activities. The highest component score in each category determines the score for the category, unless aids or devices are required. Dependence on equipment or physical assistance increases a lower score to the level of 2 to more accurately represent underlying disability. The eight category scores are averaged into an overall HAQ score on a scale from zero (no disability) to three (completely disabled). The scale is not truly continuous but has 25 possible values (i.e., 0, 0.125, 0.250, 0.375 … 3). Response is measured by a reduction of at least 0.3 unit from baseline in HAQ index.

    Mean Change From Baseline at Week 16 in Short Form (36) [SF-36] Scores
    End point description
    The SF-36 questionnaire consists of eight scales yielding two summary measures: physical and mental health. The physical health measure includes four scales of physical functioning (10 items), role-physical (4 items), bodily pain (2 items), and general health (5 items). The mental health measure is composed of vitality (4 items), social functioning (2 items), role-emotional (3 items), and mental health (5 items). To score the SF-36, scales are standardized with a scoring algorithm to obtain a score ranging from 0 to 100. Higher scores indicate better health status.

    Mean Change From Baseline at Week 24 in SF-36 Scores
    End point description
    The SF-36 questionnaire consists of eight scales yielding two summary measures: physical and mental health. The physical health measure includes four scales of physical functioning (10 items), role-physical (4 items), bodily pain (2 items), and general health (5 items). The mental health measure is composed of vitality (4 items), social functioning (2 items), role-emotional (3 items), and mental health (5 items). To score the SF-36, scales are standardized with a scoring algorithm to obtain a score ranging from 0 to 100. Higher scores indicate better health status.

    [2] - The end point is not reporting statistics for all the arms in the baseline period. It is expected all the baseline period arms will be reported on when providing values for an end point on the baseline period.
    Justification: Only arms receiving clazakizumab were reported.

    Substantial protocol amendments (globally)

    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    13 Sep 2011
    To permit the collection and storage of blood samples for use in future exploratory pharmacogenetic research.
    26 Jun 2012
    -To modify the study design to address a concern from the FDA that a small percentage of DMARD-IR/NSAID-IR PsA subjects who may be randomized to pure placebo and, therefore, not receive any active treatment which may potentially put subjects with high disease activity at risk for structural damage. -To require that all subjects planning to participate be on stable background methotrexate therapy prior to randomization.

    Interruptions (globally)

    Were there any global interruptions to the trial? No
