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   44339   clinical trials with a EudraCT protocol, of which   7369   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 ).

    Clinical Trial Results:
    A randomised, double-blind, placebo- and active-controlled parallel group study to assess the efficacy of 12 weeks of once daily treatment of two doses of orally inhaled tiotropium + olodaterol fixed dose combination (delivered by the Respimat® inhaler) in patients with moderate to severe Chronic Obstructive Pulmonary Disease (COPD)

    Due to the EudraCT – Results system being out of service between 31 July 2015 and 12 January 2016, these results have been published in compliance with revised timelines.

    General information about the trial
    Main objective of the trial
    This trial was 1 of 2 randomised, double-blind, placebo- and active-controlled parallel group Phase IIIb trials with identical protocols (replicate trials with BI trial numbers 1237.25 and 1237.26) The objective of this trial was to evaluate maximal treatment effect in forced expiratory volume in one second (FEV1) response and St. George’s Respiratory Questionnaire (SGRQ) total score and safety after 12 weeks of treatment with 2 different doses of tiotropium + olodaterol fixed dose combination solution (2.5/5μg and 5/5μg) delivered by the RESPIMAT® inhaler by comparison with placebo in patients with moderate to severe COPD.
    Protection of trial subjects
    Only subjects that met all the study inclusion and none of the exclusion criteria were to be entered in the study. All subjects were free to withdraw from the clinical trial at any time for any reason given. Close monitoring of all subjects was adhered to throughout the trial conduct.

    Notes
    [1] - The number of subjects reported to be in the baseline period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same.
    Justification: Baseline characteristics are based on the patients who were randomized after successfully completing the screening period and received at least one of the trial medication.

    		 FEV1 AUC0-3h response (change from baseline)
    End point description
    Forced expiratory volume in one second (FEV1) Area under the curve (AUC) 0-3h was calculated as the area under the FEV1-time curve from 0 to 3h post-dose using the trapezoidal rule, divided by the duration (3h) to report in litres. FEV1 AUC0-3h response was defined as FEV1 AUC0-3h minus baseline FEV1. The adjusted mean and standard error (SE) are obtained from fitting a mixed effect model repeated measures (MMRM) including fixed effects of treatment, planned test day, treatment by test day interaction, baseline, and baseline by test day interaction; patient as a random effect; spatial power covariance structure for within−patient errors and Kenward−Roger approximation of denominator degrees of freedom. The Full Analysis set (FAS) included all patients in the TS who had a baseline and at least one postbaseline measurement for any of the primary efficacy endpoints.

    		 Trough FEV1 response (change from baseline)
    End point description
    Trough FEV1 was defined as the FEV1 value at the end of the dosing interval (24 hours). It was calculated as the mean of the 2 FEV1 measurements performed 23 h and at 23 h 50 min after inhalation of study medication at day 85. Trough FEV1 response was defines as trough FEV1 minus baseline FEV1. The adjusted mean (SE) are obtained from fitting a mixed effect model repeated measures (MMRM) including fixed effects of treatment, planned test day, treatment by test day interaction, baseline, and baseline by test day interaction; patient as a random effect; spatial power covariance structure for within−patient errors and Kenward−Roger approximation of denominator degrees of freedom. The Full Analysis set (FAS) included all patients in the TS who had a baseline and at least one postbaseline measurement for any of the primary efficacy endpoints.

    The SGRQ ranges from 0 (no impairment of quality of life) to 100 (highest impairment of quality of life). The adjusted mean (SE) are obtained from fitting a mixed effect model repeated measures (MMRM) including fixed effects of treatment, planned test day, treatment by test day interaction, baseline, and baseline by test day interaction; patient as a random effect; spatial power covariance structure for within−patient errors and Kenward−Roger approximation of denominator degrees of freedom. An additional combined endpoint is defined and analysed for trial 1237.25 and 1237.26, however due to the platform limitations those could not be provided. Results can be found on CT.gov study number: NCT02006732.

    Trough FVC was defined as the FVC value at the end of the dosing interval (24 hours). It was calculated as the mean of the 2 FVC measurements performed 23 h and at 23 h 50 min after inhalation of study medication at day 85. Trough FVC response was defined as trough FVC minus baseline FVC. The adjusted mean (SE) are obtained from fitting a mixed effect model repeated measures (MMRM) including fixed effects of treatment, planned test day, treatment by test day interaction, baseline, and baseline by test day interaction; patient as a random effect; spatial power covariance structure for within−patient errors and Kenward−Roger approximation of denominator degrees of freedom.

    		 TDI focal score based on data from this individual study
    End point description
    Mahler Transitional Dyspnoea Index (TDI) focal score was performed to measure the effect of the treatment on patients' dyspnoea.(Rating scale of 3 components - change in functional impairment, change in magnitude of tasks, change in magnitude of efforts. Worst score = -9, best score = +9). The adjusted mean (SE) are obtained from fitting an MMRM model including fixed effects of treatment, planned test day, treatment by test day interaction, baseline, and baseline by test day interaction; patient as a random effect; spatial power covariance structure for within−patient errors and Kenward−Roger approximation of denominator degrees of freedom. An additional combined endpoint is defined and analysed for trial 1237.25 and 1237.26, however due to the platform limitations those could not be provided. Results can be found on CT.gov study number: NCT02006732.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    12 May 2014
    In this administrative revision of the trial protocol, medication restrictions and washout periods for bronchodilator medications were updated to define washout periods for bronchodilator medications marketed after finalisation of original protocol. Web cast training was added for sites that did not participate in hands-on training of MasterScope equipment during the investigator meeting to ensure that at least one staff member at each site was fully trained in the use of the ERT equipment.
    28 Aug 2014
    In this administrative revision of the trial protocol, the hypothesis testing strategy, text describing the hypothesis testing strategy and corresponding figure were updated to maintain consistency within the project. It was made explicit that safety laboratory tests and ECGs were to be performed locally and not collected in the database, and hence would not be analysed. Further details were added to provide clear guidance on visit rescheduling for patients recovering from acute exacerbations of COPD.

    Interruptions (globally)
    Were there any global interruptions to the trial? No

    Limitations and caveats
    Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data.
    Additional combined primary and secondary endpoints are defined and analysed for trial 1237.25 and 1237.26, however due to the platform limitations those could not be provided. Results can be found on CT.gov study number: NCT02006732.
