About
The purpose of the study is to enroll participants with uncontrolled asthma to evaluate the large and small airways and drug delivery utilizing two study drugs:
Full description
The study will comprise of 5 visits. A screening visit (V1, Week -2), with baseline assessment. At the randomization visit (V2, Week 0), patients will be randomized in a 1:1 ratio to receive one of the following treatments for 8 weeks:
A subsequent visit will be performed at 8 weeks (V3), where participants will undergo spirometry, oscillometry, and imaging. Participants will then stop the assigned treatment and undergo a washout period of 4 weeks using an unrelated maintenance ICS/LABA combination inhaler.
Following the washout period, at the next visit (V4, Week 12) participants will then be crossed over to the other treatment they did not receive at randomization.
At the final visit (V5, Week 20), patients will once again undergo spirometry, oscillometry, and imaging. In the event of premature study discontinuation, an early termination (ET) visit will be conducted and the Investigator must fill in the "Study Termination" page in the eCRF, reporting the main reason for withdrawal.
Participants who were previously screened and found ineligible due to transient or correctable conditions (e.g., recent exacerbation) may be considered for rescreening twice. Rescreening must be approved by the Principal Investigator and documented in the subject's screening log.
Rescreening will follow the same procedures as the initial screening, including informed consent, unless otherwise specified in the protocol. The reason for rescreening and any changes in eligibility status must be clearly documented in the case report form (CRF) and source documents.

Inclusion criteria
Subject's written informed consent obtained prior to any study-related procedure.
Patients aged ≥ 18 and ≤ 75 years
Confirmed diagnosis of asthma (patients must have a documented history of asthma for at least 1 year with diagnosis before the age of 40 and/or pre-bronchodilator FEV1 between 50-80% of their predicted normal value, after appropriate washout from bronchodilators)
Symptomatic on ICS/LABA treatment with ACT <20
No exacerbations in the past 3 months requiring treatment with systemic corticosteroids or emergency department visit/ in-patient hospitalization
The ability to be trained and correctly use a pressurized Meter Dose Inhaler (pMDI) and Dry Powder Inhaler (DPI)
To have a cooperative attitude and the ability to perform the required outcomes measurements (e.g. spirometry maneuvers in sitting and supine position) and the ability to understand the risks involved
WOCBP fulfilling one of the following criteria:
Female patients of non-childbearing potential defined as physiologically incapable of becoming pregnant (i.e. post-menopausal or permanently sterile, e.g. amenorrheic for ≥12 consecutive months without alternative medical cause). Permanent sterilization methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. If indicated, as per investigator's request, post-menopausal status may be confirmed by follicle-stimulating hormone levels (according to local laboratory ranges).
