Official title
A Randomized, Non-inferiority, Double-blind, Controlled, Single-dose, 2-way Cross-over Study to Assess the Potential for Airway Sensitivity Reactions With Propellants HFA-152a (Test) and HFA-134a (Reference) Administered Via Pressurized Metered Dose Inhalers in Adults Aged 18-45 With Mild Asthma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of the study is to assess the propellants,1 - Difluoroethane \[HFA-152a\] (Test) and 1,1,1,2-Tetrafluoroethane \[HFA-134a\] (Reference) for their potential to cause the airways to tighten when delivered through pressurized metered dose inhalers (pMDI). The rationale for this study is to develop a low carbon footprint alternative propellant, HFA-152a, which will have a lower impact on global warming.
