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   43873   clinical trials with a EudraCT protocol, of which   7293   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
    Primary objective of the trial: To investigate efficacy of inhaled molgramostim on NTM sputum culture conversion to negative.
    Protection of trial subjects
    Subjects could be discontinued from treatment and assessments at any time, if deemed necessary by the investigator. Potential reasons for discontinuation of treatment included lack of efficacy/worsening of disease and unacceptable AE. In case of worsening of NTM pulmonary disease, antimycobacterial treatment could be added or a dosage increase of antimycobacterial treatment could be applied as rescue treatment, according to investigator’s discretion. A safety interim analysis and data monitoring were conducted during the trial for the purpose of overseeing safety.
    Background therapy
    Anti-mycobacterial therapy was continued, if ongoing.

    The date reflects final amended protocol version 2.0. The changes were made before the protocol was submitted to any competent authority or independent ethics committee.
    23 Aug 2018
    The date reflects final amended protocol version 3.0. The number of sputum samples per visit was increased to strengthen the validity and robustness of the microbiological assessments. Definition of sexual abstinence was added.
    04 Oct 2018
    The date reflects final amended protocol version 4.0. Treatment period extended by 24 weeks to a total of 48 weeks. Dose modifications allowed after sponsor approval in case of intolerance in order to maintain subjects on treatment if deemed feasible by the investigator. CT scan added at week 48. CT scans should only be performed if this is already a part of local standard at the site. Safety laboratory sampling added at the 12-week Follow-up visit in order to assess the laboratory parameters.
