Eco-Friendly asthma inhaler passes safety check in major trial
NCT ID NCT06264674
First seen Jun 24, 2026 · Last updated Sep 11, 2026 · Updated 3 times
Summary
This study tested a new, environmentally friendly propellant (HFA-152a) in a common asthma inhaler (CHF5993) to see if it is as safe as the current propellant. Over 800 adults with moderate to severe asthma used the inhaler twice daily for 12 weeks. The main goal was to check for any immediate breathing problems after using the new inhaler.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- CHF5993 (a combination of beclometasone, formoterol, and glycopyrronium) in an inhaler with a new propellant (HFA-152a)
- What this could lead to
- If successful, this could lead to a more environmentally friendly asthma inhaler that works just as safely as current ones.
- What could go wrong
- This trial is focused on safety and uses a new propellant, so it may not show any improvement in asthma control. The results are specific to moderate to severe asthma and may not apply to all patients.
