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   44020   clinical trials with a EudraCT protocol, of which   7318   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 investigate the efficacy of BI 1015550 compared to placebo based on the change from baseline in forced vital capacity (FVC) in patients with Idiopathic Pulmonary Fibrosis (IPF). To investigate the safety and tolerability of BI 1015550 in patients with IPF.
    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. Rescue medication was allowed for all subjects as required.

    Recruitment
    Recruitment details
    		 This was a trial with a randomised, placebo-controlled, double-blind, parallel-group design over 12 weeks, including a screening period of up to 44 days, a 12-week treatment period, and a 1-week follow-up period in patients with idiopathic pulmonary fibrosis (IPF) stratified by baseline antifibrotic treatment.

    Pre-assignment
    Screening details
    		 All subjects were screened for eligibility prior to participation in the trial. Subjects attended a specialist site which ensured that they (the subjects) strictly met all inclusion and none of the exclusion criteria. Subjects were not to be allocated to a treatment group if any of the entry criteria were violated.

    Arm description
    		 Idiopathic pulmonary fibrosis (IPF) patients on antifibrotic treatment with nintedanib or pirfenidone at baseline were administered placebo matching BI 1015550 taken orally as film-coated tablets (matching the respective BI 1015550 tablets) twice daily, in the morning and in the evening for 12 weeks.

    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: Out of the 233 enrolled subjects, 147 subjects were randomized.

    The change from baseline in Forced vital capacity (FVC) at 12 weeks. Data were analysed with a restricted maximum likelihood (REML)-based approach using a mixed model with repeated measures (MMRM). The analysis included the fixed, categorical effect of treatment at each visit, and the fixed, continuous effects of baseline FVC at each visit. Visit was treated as the repeated measure, with an unstructured covariance structure used to model the within-patient measurements. Full Analysis Set (FAS): all patients who received at least one dose of trial drug and who had a baseline and at least one post-baseline measurement available for Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1) or Diffusion Capacity of the Lung for Carbon Monoxide (DLCO).

    Statistical analysis description
    Adjusted means in the placebo group were combined with the meta-analytic predictive priors derived based on the clinical trials in the nintedanib clinical development program in IPF. In order to evaluate the treatment effects, the posterior distribution for the treatment difference of BI 1015550 versus placebo with respect to the primary endpoint was used. The median of the posterior distribution for the treatment difference (and 95% credible intervals) was calculated.

    Placebo, Antifibrotics at baseline
    Reporting group description
    		 Idiopathic pulmonary fibrosis (IPF) patients on stable antifibrotic treatment with nintedanib or pirfenidone at baseline were administered placebo matching BI 1015550 taken orally as film-coated tablets (matching the respective BI 1015550 tablets) twice daily, in the morning and in the evening for 12 weeks. During the 12-weeks of administration of BI 1015550 patients stayed on their stable background therapy of nintedanib or prifenidone.

    Reporting group title
    Placebo, Non-antifibrotics at baseline
    Reporting group description
    		 Idiopathic pulmonary fibrosis (IPF) patients not on stable antifibrotic treatment at baseline were administered placebo matching BI 1015550 taken orally as film-coated tablets (matching the respective BI 1015550 tablets) twice daily, in the morning and in the evening for 12 weeks. Patients were not expected to start antifibrotic treatment during the 12 weeks of placebo treatment.

    Substantial protocol amendments (globally)
    Were there any global substantial amendments to the protocol? Yes
    Date
    Amendment
    27 May 2020
    In this revision of the Clinical Trial Protocol (CTP), the dose and regimen of trial drug were deleted from the title to fulfil internal rules of disclosure.
    02 Jun 2020
    In this revision of the Clinical Trial Protocol (CTP), the table of risks was updated so that the risks associated with blood sampling, High-Resolution Computed Tomography (HRCT) and lung measurements (Pulmonary Function Test (PFT) and Diffusion Capacity of the Lung for Carbon Monoxide (DLCO)), as well as the risk and mitigation plan for placebo use, were legible. The procedures in case of acute Idiopathic Pulmonary Fibrosis (IPF) exacerbation were clarified. The description of Electrocardiogram (ECG) recording was corrected to remove the postdose ECG at Visit 2 and to clarify that triplicate ECGs were not expected (single ECG were to be performed). Regarding the optional substudy on digital lung auscultation test, fewer points of auscultations were to be used and the results were not meant to be reported in the Clinical Trial Report (CTR). Regarding the optional substudy on 24-hour cough measurements, an inclusion criterion to enter the substudy was added to ensure that participants coughed enough; the evaluations to be performed were clarified.
    09 Sep 2020
    In this revision of the Clinical Trial Protocol (CTP), the trial-related risks were updated to add the risk assessment due to the Coronavirus Disease 2019 (COVID-19) pandemic. An exclusion criterion was added to exclude patients with a Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection as this was a potential additional risk. The criteria to discontinue trial treatment were updated to include the patients who meet Adverse Event of Special Interest (AESI) definition of hepatic injury and the patients who experience infection with SARS-CoV-2 (for safety reasons).

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