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 ).

    General information about the trial
    Main objective of the trial
    To assess the effects of olodaterol alone versus olodaterol plus tiotropium given once daily as add-on therapy to pre-existing inhaled corticosteroids using impulse oscillometry in smoking asthmatics
    Protection of trial subjects
    The study Sponsor carried out a study risk assessment before issuing approval. The study was approved by the East of Scotland Research Ethics Service (Ref: 15/ES/0032). Informed consent was obtained from all participants. Participants were checked against all inclusion and exclusion criteria and only participants deemed clinically stable were recruited into the study. A medically-qualified person confirmed that it was safe for the participant to receive the IMP. Participants were issued a peak flow and symptom diary to assess clinical stability throughout the study. Participants were also issued an out-of-hours contact card with the mobile number carried by medical staff for advice if they encountered any adverse effects. One week after the end of each treatment period, patients were contacted by phone as a safety follow-up.
    Background therapy
    After the screening visit, participants entered a 2-4 week run-in period when LABA or LAMA were stopped and participants’ ICS dose was rounded to equivalent reference ICS as HFA-BDP (Clenil Modulite pMDI). This dose of Clenil was then continued unchanged throughout the study.
    Evidence for comparator
    We used the LABA olodaterol (OLO), and the combination of olodaterol with the LAMA tiotropium (OLO/TIO) both delivered via the soft mist Respimat inhaler. The rationale for choosing the Respimat device was that it was possible to deliver the OLO and OLO/TIO via the same device.

    Recruitment
    Recruitment details
    Subject recruitment began 11 July 2016 and the study completed on 22 May 2019. Of the 29 patients screened, 17 were randomised and 16 completed per protocol and were included in the final analysis.

    Pre-assignment
    Screening details
    Diagnosis of persistent asthma, current smokers, age 18-65 years, taking at least 400μg per day of ICS (as HFA-BDP Clenil equivalent dose). Patients with COPD or ACO were excluded. Patients who had an asthma exacerbation requiring systemic corticosteroids within 1 month of screening or requiring hospital admission within 3 months were excluded.

    Notes
    [1] - The number of subjects reported to be in the baseline period is not equal to the worldwide number of subjects enrolled in the trial. It is expected that these numbers will be the same.
    Justification: The worldwide number enrolled is the number of subjects screened into the study (29). The number of subjects in the baseline period is the number who were randomised into the study (17). Of these 17 subjects, 16 completed the study per protocol and were able to be analysed.
