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   43839   clinical trials with a EudraCT protocol, of which   7280   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.

    E. General Information on the Trial
    E.1 Medical condition or disease under investigation
    E.1.1Medical condition(s) being investigated
    Acute Stroke
    MedDRA Classification
    E.1.3Condition being studied is a rare disease No
    E.2 Objective of the trial
    E.2.1Main objective of the trial
    The primary outcome measures are early changes in neurological deficit (difference in NIH Stroke Score from admission to one week) and death and disability (Mod. Rankin>3) at 6 months.
    E.2.2Secondary objectives of the trial
    Secondary outcome measures are discharge destination (home, institution, still in hospital, death), activities of daily living (Barthel Index), extended activities of daily living ( Nottingham Extended Activities of Daily Living Index) and Quality of life (EuroQuol) at 6 months.

    We will also report outcomes which stroke patients and their carers felt were important but which are not included in standard stroke outcome assessment tools such as sleep, memory and speech.

    Predictors of death and disability (Mod. Rankin >3) or neurological deterioration (an increase of the NIHSS >4 from admission to week 1) will be examined using multiple logistic regression and all baseline clinical characteristics (including NIHSS subscores) as factors.
    E.2.3Trial contains a sub-study No
    E.3Principal inclusion criteria
    All adult patients with an acute stroke will be eligible to be considered for study participation. There are no definite guidelines for oxygen treatment after acute stroke, and there is uncertainty amongst stroke physicians about who should be given oxygen and for how long. The eligibility criteria for inclusion into the trial reflect this uncertainty, and allow for randomization of all acute stroke patients who do not have definite indications or definite contraindications for oxygen treatment.

    Hence adult patients will be eligible for trial inclusion if: They were admitted with symptoms of an acute stroke within the preceding 24 hours, and in the doctor's opinion there is no clear indication for and no clear contraindication against oxygen treatment.

    The diagnosis of stroke will be made by history and clinical examination and is at the discretion of the admitting doctor. It will based on the WHO criteria (rapidly developing clinical signs of focal or global disturbance of cerebral function, with symptoms lasting 24 hours or longer, or leading to death, with no apparent cause other than of vascular origin). Within the first 24 hours of symptom onset a definite distinction between a stroke and a transient ischaemic attack cannot be made. However, most patients who still have persistent symptoms after one hour will be confirmed to have a stroke. Since waiting for 24 hours for confirmation would unnecessarily delay treatment we omitted the time element from the definition of stroke for the purposes of trial inclusion.
    E.4Principal exclusion criteria
    Patients will be excluded from the trial if the responsible doctor considers the patient to have definite indications for or contraindications to oxygen treatment at a rate of 2-3 L/min. The decision will be left to the responsible clinician. This exclusion criterion has been chosen to ensure that all patients are treated according to best medical practice.

    Potential indications for oxygen treatment could be: oxygen saturation on air <90%, hypoxia associated with acute left ventricular failure, severe pneumonia, pulmonary embolus, and chronic respiratory failure patients treated with long term oxygen at home.

    Potential contraindications to fixed dose oxygen treatment could be type 2 respiratory failure and very severe hypoxia.
    E.5 End points
    E.5.1Primary end point(s)
    The primary outcome measures are early changes in neurological deficit (difference in NIH Stroke Score from admission to one week) and death and disability (Mod. Rankin>3) at 6 months.

An answer of yes could have included women of child bearing potential whether or not they would be using contraception. The answer should therefore be understood in that context. This trial was recorded in the database on 2007-03-28. Yes

    F.3.3.6.1Details of subjects incapable of giving consent
    Dysphasia and confusion are common after a stroke. Excluding patients unable to give fully informed consent would mean substantial proportion of potential subjects would not be able to participate, and bias recruitment towards milder strokes.
