Summary

This trial is comparing two types of inhalers, one with a new propellant (HFO) and one with a standard propellant (HFA), in healthy participants. The goal is to see if the new propellant helps clear mucus from the lungs as effectively as the standard one. Participants will use each inhaler for a period of time, with a break in between, to measure and compare their effects.

Who is the study for?
Healthy adults, aged 18-60, non-smokers with a BMI of 18-35 kg/m2 and weight between 50-120 kg. They must have normal lung function (FEV1 ≥80% predicted), be able to use an MDI correctly, and comply with study requirements. Women of childbearing potential must use effective birth control and have a negative pregnancy test.
What is being tested?
The trial is testing the effect of two different propellants used in metered-dose inhalers (MDIs) on mucociliary clearance in healthy participants: HFO MDI versus HFA MDI. Mucociliary clearance is how your lungs clear mucus and debris.
What are the potential side effects?
Since this trial involves healthy volunteers using inhaler propellants without active medication, significant side effects are not expected. However, minor throat irritation or cough could occur due to inhaling substances from the MDI.

Other Research
Common treatments for mucociliary clearance include hypertonic saline, mannitol, and mucolytic agents like N-acetylcysteine. Hypertonic saline works by drawing water into the airways, thinning mucus and making it easier to clear. Mannitol, an osmotic agent, similarly helps to hydrate and loosen mucus. Mucolytic agents like N-acetylcysteine break down the chemical structure of mucus, reducing its viscosity. These mechanisms are crucial for patients with mucociliary clearance issues as they help to maintain airway patency, reduce infection risk, and improve overall lung function. Treatments like HFO MDI propellant are being studied for their potential to enhance these effects by improving the delivery and distribution of these agents within the airways.
