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   44364   clinical trials with a EudraCT protocol, of which   7388   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
    The objective of this trial is to assess the efficacy and safety of aerosolized liposomal cyclosporine A (L-CsA) as add-on therapy to standard of care (SoC) as compared to SoC alone in single lung transplant recipients with chronic lung allograft dysfunction (CLAD)-bronchiolitis obliterans syndrome (BOS).
    Protection of trial subjects
    The clinical study was performed in accordance with the principles that have their origin in the Declaration of Helsinki, and with local regulations. The study was carried out in accordance with the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) notes for guidance on Good Clinical Practice (GCP). Investigators ensured a close follow-up of safety signals, and that everything has been done to reduce the burden of study procedures (e.g. no painful procedures, etc.).
    Background therapy
    Standard of Care (SoC) therapy: regardless of treatment allocation, all patients continued to receive their SoC regimen for maintenance of the lung allograft. Maintenance immunosuppressive therapy including tacrolimus, a second agent such as, but not limited to, MMF or azathioprine, and a systemic corticosteroid such as prednisone as third agent was administered according to institutional standards.

    5 mg L-CsA, powder for nebulization solution for inhalation use, administered with the nebulizer eFlow. L-CsA 5 mg/1.25 mL was administered twice daily for 48 weeks. More precisely, each patient received two L-CsA administrations per day, one in the morning and one in the evening. The inhalations were scheduled to be taken approximately 12 hours apart, e.g., at 8:00 a.m. and 8:00 p.m. each day. Eligible patients should be on a maintenance regimen of immunosuppressive agents including tacrolimus, a second agent such as but not limited to MMF or azathioprine, and a systemic corticosteroid such as prednisone as third agent. The regimen must be stable within 4 weeks prior to randomization with respect to the therapeutic agents. Patients receiving azithromycin for prophylaxis or treatment of BOS, must be on a stable regimen for a least 4-weeks prior to randomization and will continue to receive azithromycin during the trial as deemed appropriate by the investigator.

    FEV1 is the Forced Expiratory Volume in One Second. For FEV1 were considered primary the data collected from the on site COMPACT study spirometer. Baseline is the mean of the best FEV1 obtained with the study spirometer at Screening Visit and the pre-randomization best FEV1 obtained at the Baseline Visit (V1).The primary efficacy analysis was carried out using a Linear Mixed Model (LMM) for repeated measures, using all observed available FEV1 measurements. In case of death or re-transplantation events, FEV1 was imputed as zero at each nominal day post event.

    End point description
    The progression of BOS is defined as the earliest of the following: - Absolute decrease from baseline in FEV1 ≥ 10% or ≥ 200 mL and absolute decrease in FEV1/FVC of > 5% (if a patient had an event that met this criterion for progression of BOS, progression of BOS must have been confirmed by measurements that were taken with COMPACT spirometer at least 2 weeks apart) OR - Worsening of BOS grade, OR - Re-transplantation, OR - Death from respiratory failure. Rules for censoring progression of BOS are set. More than one type of event might correspond to the event of BOS progression (even those occurring on the same date). In case progression of BOS was defined by more than one criterion on different dates, the earliest event date was considered, i.e., the date closer to randomization was used as the progression date.

    Acute tolerability of IMP (L-CsA) during initial dosing was determined by measuring spirometry prior to administration of L-CsA as well as 1 hour and 4 hours after completion of IMP inhalation. A decline of ≥20% in FEV1 associated with symptoms could have warranted IMP discontinuation. Parameters reflecting acute tolerability of IMP were: spirometry, cough, or dyspnea.
