Comparison Between CHF5993 pMDI 200/6/12.5 µg HFA-152a VS CHF5993 pMDI 200/6/12.5 µg HFA-134a in Subjects With Asthma (TRECOS).

Korábbi kezelés

• History of near fatal asthma, hospitalisation for asthma in intensive care unit which in the judgement of the Investigator may place the subject at undue risk, emergency room access for asthma in the previous 6 months before enrolment;
• Asthma exacerbation requiring systemic corticosteroids (SCS) or emergency room admission or hospitalisation within 4 weeks prior to study entry and/or during the run-in period (to be checked again prior to randomisation);
