Outcome Measures

Primary Outcomes (2)

  • Mucociliary Clearance Rate -- Right Whole Lung -- Percent Particle Retention at 2 Hours (PPR2) on Day 8

    MCC rate was assessed by the percent particle retention at 2 hours (PPR2) after the inhalation of radiolabelled particles. Results are shown as adjusted mean (95% CI) for change from baseline in PPR2 (right whole lung) on Day 8, considering either HFA-152a and HFA-134a propellants. PPR2=Percent particle retention at 2 h after the inhalation of radiolabelled particles

    2 hours post inhalation of radiolabelled particles

  • Mucociliary Clearance Rate -- Right Whole Lung -- Percent Particle Retention at 4 Hours (PPR4) on Day 8

    Mucociliary Clearance rate (MCC) rate, as assessed by the percent particle retention (PPR) (in right whole lung) at 4 h after the inhalation of radiolabelled particles (PPR4), on Day 8. Results are shown as adjusted mean (95% CI) for change from baseline in PPR4 (right whole lung) on Day 8, considering either HFA-152a and HFA-134a propellants. PPR4=Percent particle retention at 4 h after the inhalation of radiolabelled particles

    4 hours post inhalation of radiolabelled particles

Other Outcomes (1)

  • Mucociliary Clearance -- AUC(0-4) -- Right Whole Lung Region

    Post inhalation of radiolabelled particles; baseline and 4 h after inhalation of the radiotracer on Day 8.

  • Body Mass Index (BMI) between 18 and 30 kg/m2 (extremes inclusive);
  • Non-smokers or ex-smokers who smoked \< 5 pack-years and stopped smoking \> 5 years prior to screening;
  • Good physical and mental status at screening and before randomisation;
  • Vital signs within normal limits at screening; body temperature \< 37.5°C;
  • lead digitised electrocardiogram (ECG) in triplicate considered as normal at screening;
  • Lung function measurements within normal limits at screening;
  • Female subjects fulfilling one of the following criteria: Women of non-childbearing potential (WONCBP). Women of childbearing potential (WOCBP) with fertile male partners: they and/or their partner must be willing to use a highly effective birth control method preferably with low user dependency, from the signature of the informed consent form (ICF) and until the follow-up call.
  • Male subjects fulfilling one of the following criteria: Fertile male subjects with a pregnant or non-pregnant WOCBP partner: they must be willing to use male condom, from the signature of the ICF until the follow-up call.

You may not qualify if:

  • Participation in another clinical study with an investigational drug in the 3 months or five half-lives of that investigational drug (whichever is longer) preceding the administration of the study treatment;
  • Clinically relevant and uncontrolled respiratory, cardiac, hepatic, gastrointestinal, renal, endocrine, metabolic, neurologic, or psychiatric disorders ;

  • Subjects with history of breathing problems (i.e. history of asthma including childhood asthma);
  • Positive serology test for human immunodeficiency virus (HIV) 1 or HIV2 serology at screening;
  • Positive results from the hepatitis serology, indicating acute or chronic hepatitis B or hepatitis C at screening;
  • Blood donation or blood loss (≥ 450 mL) during the 2 months prior to screening or randomisation;
  • Positive urine test for cotinine at screening or prior to randomisation;
  • Documented history of alcohol abuse within 12 months prior to screening, an average weekly alcohol intake of greater than 14 units, or a positive alcohol breath test at screening or prior to randomisation;
  • Documented history of drug abuse within 12 months prior to screening or a positive urine drug screen evaluated at screening or prior to randomisation;
  • Intake of non-permitted concomitant medications in the predefined period prior to screening or prior to randomisation;
  • Presence of any current infection, or previous infection that resolved less than 1 week prior to screening or to randomisation;
  • Known intolerance and/or hypersensitivity to any of the excipients contained in the formulation used in the study;
  • Documented coronavirus disease 2019 (COVID-19) diagnosis within the last 2 weeks, or associated complications/symptoms which have not resolved within 2 weeks prior to screening or prior to randomisation;
  • Heavy caffeine drinker;
