What this study is testing

To demonstrate the therapeutic equivalence of CHF5993 pMDI HFA-152a versus (vs.) CHF5993 pMDI HFA-134a in terms of change from baseline in forced expiratory volume in 1 second (FEV1) area under the curve from time zero to 4 hours (h) (AUC0-4h) on Day 1 and in pre-dose FEV1 on Day 28 in adults with mild to moderate, controlled/partly controlled asthma

Who can take part

You may be able to join if

1. Informed consent: obtained prior to any study-related procedure
10. Rescue medication: subjects must be able to replace their current rescue medication with a salbutamol (i.e. albuterol) inhaler for use as needed for the duration of the study
11. Current therapy: subjects must be able to safely discontinue their asthma medications (ICS with or without LABA) during the run-in period and for the remainder of the study
12. Spacer non-use: subjects must be able to inhale the study treatment without using a spacer
13. Subjects must have a willingness and ability to: a. Be trained to correctly use the pMDI inhalers and the electronic diary (e-Diary); b. Read/write; c. Perform all study-related procedures, including technically acceptable spirometry and e-Diary completion; d. Understand the risks involved
14. Female subjects: a. Woman of childbearing potential (WOCBP) using a highly effective birth control method (refer to protocol for more details) or b. Women of non-childbearing potential

You likely can't join if

1. History of high-risk asthma: history of near fatal asthma or hospitalisation for asthma in intensive care unit, inpatient setting or emergency room access for asthma in the previous 6 months prior to screening, which in the judgement of the Investigator may place the subjects at undue risk
10. Electrocardiogram (ECG) criteria: any clinically significant abnormal 12-lead ECG that, in the Investigator’s opinion, would affect efficacy or safety evaluations or place the subjects at risk
11. ECG QTcF: male subjects with a QT interval corrected using Fridericia’s formula (QTcF) >450 milliseconds (ms) and female subjects with a QTcF >470 ms at Screening Visit (V1) are not eligible
12. Other medical conditions: previous medical history, evidence of an uncontrolled, severe, intercurrent illness, or any clinically relevant abnormal findings in haematology, clinical chemistry, or urinalysis
13. Concurrent diseases: subjects with a medical history or current diagnosis of narrow-angle glaucoma, symptomatic prostatic hypertrophy, urinary retention, or bladder neck obstruction that, in the opinion of the Investigator, would prevent the use of anticholinergic agents
14. Subjects receiving non-selective β2-blockers, quinidine and quinidine-like anti-arrhythmics, tricyclic anti-depressants, monoamine oxidase inhibitors, cytochrome P450 3A4 inhibitors and non-potassium sparing diuretics within 4 weeks prior to screening (unless the diuretic is administered as a fixed-dose combination with a potassium-conserving drug)

6. Stable asthma therapy: a stable maintenance treatment for at least 4 weeks prior to screening with: a.low or medium doses of ICS alone; or b.low or medium doses of ICS + LABA (fixed or free combination). Low and medium doses of ICS are defined as non-extrafine BDP 200-500 μg and >500-1000 μg respectively, or estimated clinically comparable dose per the Global Initiative for Asthma 2024

8. Lung function: pre-BD FEV1 >40% and <90% of the predicted normal value, after appropriate wash-out from BDs, at the Screening Visit (V1)
9. Bronchodilator responsiveness: a demonstrated increase in either FEV1 or forced vital capacity of >12% and >200 mL from baseline within 30 minutes (min) after inhalation of 400 μg salbutamol (i.e. albuterol) pMDI at the Screening Visit (V1)
