Xenon MRI Probing vEntilation Response to Triple Therapy (QVM149)
The purpose of this study is to compare treatment with QVM149, an inhaler that contains three types of asthma medications compared to an inhaler that contains two types of asthma medications. Both inhalers contain an inhaled corticosteroid, which reduces inflammation in the lungs, and a medication that helps to open up the airways. The investigational inhaler, QVM149, contains a third medication that also works to open up the airways. The investigators will measure the difference in these two treatments with magnetic resonance imaging (MRI) using a special technique using xenon gas to show how gas spreads in the lungs. In healthy lungs, the gas fills the lungs evenly, but in unhealthy lungs, the gas may fill the lungs unevenly and they will appear patchy. The patchy areas are called ventilation defects. A CT of the chest will be done to assess the structure of the lungs. The investigators will also use lung function testing and questionnaires to evaluate the differences between these therapies.
A single site, two arm, randomized, open-label study in participants with asthma, who demonstrate visually obvious ventilation defects despite being on ICS/LABA was chosen to evaluate the capability of QVM149 150/50/160 μg once daily as compared to high dose dual therapy (ICS/LABA) to improve ventilation heterogeneity. According to the design of the study, hyperpolarized Xenon-129 (129Xe) will be used to measure ventilation defects in asthma participants as ventilation defect percent (VDP). A low-dose chest CT acquired within a few minutes of MRI will provide a way to measure both airway and parenchymal abnormalities. The selection of the QVM149 150/50/160 μg was made in order to keep the ICS dose equipotent to baseline therapy and to the active comparator arm and to directly compare the addition of a long-acting muscarinic antagonist (LAMA) versus continuing the therapy with high dose dual therapy (ICS/LABA).
This study will be a single site, two arm, randomized, open-label study with the following treatment:
The study will consist of a screening/inclusion period of 1-5 days, followed by a treatment period of 14 days. The evaluation team including MRI observers will be blinded to treatment.
At Visit 101, informed consent will be obtained before any study related assessments or procedures are performed. Asthma medications and eligibility criteria will be reviewed. Furthermore, at Visit 101, safety assessments including electrocardiography (ECG), hematology, blood chemistry, urinalysis, and spirometry to test reversibility will be performed. Once the above criteria are met, participants will move on to Visit 102.
At Visit 102 all additional assessments, including MRI to detect visually obvious ventilation defects, low-dose chest CT, and Pulmonary Function Test assessments including spirometry, plethysmography, Lung Clearance Index (LCI) and Forced Oscillation Technique (FOT) will be conducted. Participants who qualify will then be randomized and entered into the 14 days treatment period and continue with the assessments according to study protocol. Participants will be supplied with open-label Indacaterol/Glycopyrronium/ Mometasone 150/50/160 μg o.d. delivered as powder in hard capsules via Breezhaler or continue with their previously prescribed high dose dual therapy (ICS/LABA) in any approved drug formulation and delivery device, which will be used during the study treatment period and stopped at Visit 201.
Upon completion of the study treatment period at Visit 201, all participants will undergo post-treatment assessments, including MRI, pre- and post-salbutamol pulmonary function testing including spirometry, plethysmography, LCI, FOT, and asthma questionnaires.
A final visit, Visit 301 will be scheduled for safety assessments. All participants will undergo vital signs, spirometry, ECG, bloodwork and urinalysis.
Inclusion Criteria:
Written informed consent must be directly obtained from legally competent participants before any study- related assessment is performed.
Male and female adult participant ≥ 18 years of age and ≤ 80 years of age.
Participants with a confirmed clinical diagnosis of asthma by a respirologist for a period of at least 6 months prior to Visit 101.
Participants who demonstrate reversibility in FEV1 by one of :
Participants who have used high dose dual therapy (ICS/LABA) for asthma for at least 3 months and at a stable dose equivalent to high dose ICS for at least 1 month prior to Visit 101 (please refer to Table 1-1 for ICS dosages).
Participants with visually obvious MRI ventilation defects at Visit 102.
Pre-bronchodilator FEV1 of < 85% of the predicted normal value for the participant after withholding bronchodilators prior to spirometry at Visit 101.
Exclusion Criteria:
Participants meeting contraindications for undergoing an MRI such as participants with MRI-sensitive implants, tattoos with MRI-sensitive dye and severe claustrophobia.
Currently smoking or vaping any substance (e.g. nicotine, cannabis) at Visit 101 or within 12 months of visit 101.
Ex-smoker of nicotine or cannabis with a smoking history of ≥ 10 pack years or 20 joint years (Note: 1 pack is equivalent to 20 cigarettes. 10 pack years = 1 pack /day x 10 yrs., or ½ pack/day x 20 yrs. 1 joint year is equivalent to 1 joint/day x 1 year)
Participants diagnosed with Chronic Obstructive Pulmonary Disease (COPD). Diagnoses of asthma- COPD overlap syndrome may be eligible.
Participants who have had an asthma attack/exacerbation requiring systemic steroids, hospitalization and/or emergency room visit within 6 weeks of Visit 101 or a respiratory tract infection requiring antibiotics within 4 weeks prior to Visit 101. If participants experience an asthma attack/exacerbation requiring systemic steroids or hospitalization or emergency room visit between Visit 101 and Visit 201, they will be withdrawn from the study but may be re-screened 4 weeks after recovery from the exacerbation.
Participants treated with a LAMA for asthma within 3 months prior to Visit 101.
Participants with narrow-angle glaucoma, symptomatic benign prostatic hyperplasia (BPH) or bladder- neck obstruction or severe renal impairment or urinary retention. BPH participants who are stable on treatment can be considered.
Participants with a history of chronic lung diseases other than asthma, including (but not limited to) sarcoidosis, interstitial lung disease, cystic fibrosis, clinically significant bronchiectasis and active tuberculosis.
Use of other investigational drugs within 30 days (e.g. small molecules) / or until the expected pharmacodynamic effect has returned to baseline (e.g. biologics), whichever is longer.
History of hypersensitivity to any of the study treatments or its excipients or to other drugs of similar chemical classes.
Participants with paroxysmal (e.g., intermittent) atrial fibrillation are excluded. Participants with persistent atrial fibrillation as defined by continuous atrial fibrillation for at least 6 months and controlled with a rate control strategy (i.e., selective beta blockers, calcium channel blocker, digoxin or ablation therapy) for at least 6 months may be considered for inclusion. In such participants, atrial fibrillation must be present at Visit 101 with a resting ventricular rate < 100/min.

Concomitant use of agents known to prolong the QT interval unless it can be discontinued for the duration of study. Decisions about the discontinuation of such agents will be made between the Qualified Investigator and participant.
Participants with a history of long QT syndrome or whose QTc measured at Visit 101 (Fridericia method) is prolonged (> 450 msec for males and > 460 msec for females). These participants may not be rescreened.

In case of use of hormonal contraception, women should have been stable on the same pharmacological agent for a minimum of 3 months before Visit 101. Women are considered post-menopausal and not of child-bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow-up hormone level assessment is she considered not of childbearing potential.
