研究概览
简要总结
The primary objective of this study was to assess the effect of multiple doses of the HFA-152a propellant and the HFA-134a propellant on mucociliary clearance (MCC).
详细描述
This clinical trial was a Phase I, single-centre, multiple-dose, randomised, open-label, controlled, 2-way cross-over study to assess the effect on MCC of the new HFA-152a propellant (5 inhalations BID for 8 days) versus the marketed HFA-134a propellant (5 inhalations BID for 8 days) in adult healthy volunteers by measuring the clearance from the lungs of inhaled radioaerosol.
A total of 20 subjects were randomised into the study.
Standard safety assessments was conducted during the Study, including safety blood and urine laboratory tests, vital signs, physical examinations, ECGs, spirometry, and observations of any adverse events (AE).

结局指标
主要结局
Mucociliary Clearance Rate -- Right Whole Lung -- Percent Particle Retention at 2 Hours (PPR2) on Day 8
时间窗: 2 hours post inhalation of radiolabelled particles
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
Mucociliary Clearance Rate -- Right Whole Lung -- Percent Particle Retention at 4 Hours (PPR4) on Day 8
时间窗: 4 hours post inhalation of radiolabelled particles
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
