Pivotal Trial

Summary

This trial aims to compare how well an approved asthma medication works when it is delivered using a new type of propellant called HFO, versus the current propellant called HFA, in people with asthma

Who is the study for?
This trial is for individuals with asthma. Participants should be stable on their current asthma medications and have a history of the disease. Specific details about inclusion or exclusion criteria are not provided, but typically these would cover age range, severity of asthma, and any other health conditions that might affect safety or results.
What is being tested?
The study is testing the effectiveness of an approved asthma medication (BDA) using a new propellant (HFO), compared to the same medication with its current propellant (HFA). The goal is to see if lung function remains consistent when switching propellants in inhalers.
What are the potential side effects?
While specific side effects are not listed for this trial, common side effects from BDA inhalers may include throat irritation, headache, coughing, and possibly an increased heart rate. The change in propellant may also bring unforeseen reactions which this trial aims to uncover.
