Therapeutic Equivalence of CHF5993 pMDI 100/6/12.5 µg HFA-152a in Subjects With Mild to Moderate Asthma

This global study aims to compare whether the investigational inhaler with the new HFA-152a propellant is as safe, effective and well tolerated in patients with asthma as the inhalers that use the existing HFA-134a propellant. HFA-152a is a propellant gas that is designed to have a lower global warming potential and to be more climate friendly. The study will be conducted in Europe, Latin America, Ukraine, South Africa and United Kingdom. It is planned to randomize 468 patients.
