ClinConnect Summary

This clinical trial is investigating a new way to deliver an asthma treatment called BDA using a different propellant (HFO) compared to the currently approved propellant (HFA). The goal is to see if the new delivery method works as well as the old one in helping people with asthma breathe better. The trial is currently recruiting participants aged 18 and older who have been diagnosed with asthma for at least a year. Eligible participants should either not be on daily inhaled asthma medication or be stable on a low-dose inhaled treatment for a certain period.

If you join this study, you'll undergo some breathing tests to check your lung function and see if the treatment is suitable for you. Throughout the trial, you'll receive the study medication and be monitored closely to ensure it's safe and effective. It’s important to note that certain conditions and recent medical events may disqualify you, so discussing your health history with the study team is essential. This research could help improve asthma treatments for everyone in the future!

Eligibility criteria

• Inclusion Criteria:
• • Participant must be ≥ 18 years of age at the time of signing the ICF.
• • Participants who have physician diagnosed asthma as defined by GINA for at least 12 months prior to Visit 1.
• • Eligible participants are on either a) no daily inhaled maintenance therapy or b) daily inhaled maintenance therapy with low-dose ICS or low-dose ICS-LABA. Participants who are on low-dose ICS maintenance therapy are required to be stable on therapy for a minimum of 3 months prior to Visit 1; participants using low-dose ICSLABA maintenance regimens are required to be stable on therapy for a minimum of 6 months prior to Visit 1.
• • Participants with a pre-bronchodilator FEV1 of ≥ 60% and \< 90% predicted normal at Visit 1 or Visit 1a.
• • Participants with a pre-dose FEV1 of ≥ 60% and \< 90% predicted normal at Visit 2 that is within ± 20% of their Visit 1 pre-bronchodilator FEV1.
• • Participants who demonstrate bronchodilator responsiveness defined as a \> 12% and \> 200 mL increase in FEV1 relative to baseline following administration of study provided SABA at Visit 1 or Visit 1a.
• • Participants able to demonstrate acceptable spirometry performance as defined by the acceptability and repeatability criteria in the ATS/ERS Standardization of Spirometry 2019 update
• • Participants who are willing and, in the opinion of the investigator, able to adjust current asthma therapy, as required by the protocol.
• • Participants with a body mass index \< 40 kg/m2.
• • Females must not be of childbearing potential or, if of childbearing potential, using a form of birth control
• Exclusion Criteria:
• • Confirmed or suspected diagnosis of COPD or clinically significant non-asthma airway/lung disease.
• • Systemic corticosteroid use (eg, prednisone for 3 or more days or a single depo-injectable dose of corticosteroids) for any respiratory, immune, or allergy-attributed disease within 6 months prior to Visit 1.
• • An upper respiratory infection requiring antibiotic treatment that is not resolved within 7 days prior to Visit 1.
• • A lower respiratory infection in the 4 weeks prior to Visit 1.
• • Life-threatening asthma defined as any history of significant asthma episode(s) requiring admission to an intensive care unit, positive pressure ventilation associated with hypercapnia, respiratory arrest, hypoxic seizures, or asthma-related syncopal episode(s) within 5 years of Visit 1.
• • Hospitalization due to asthma within 12 months or systemic corticosteroid usage (eg, prednisone for 3 or more days or a single depo-injectable dose of corticosteroids) for asthma within 6 months prior to Visit 1.
• • A severe asthma exacerbation during the run-in period
• • An ePRO device alert during the run-in period with investigator-confirmed worsening asthma symptoms
• • Historical or current evidence of a clinically significant disease including, but not limited to: cardiovascular (eg, congestive heart failure, known aortic aneurysm, clinically significant cardiac arrhythmia, coronary heart disease), hepatic, renal, hematological, neuropsychological, endocrine (eg, uncontrolled diabetes mellitus, uncontrolled thyroid disorder, Addison's disease, Cushing's syndrome), or gastrointestinal (eg, poorly controlled peptic ulcer, gastroesophageal reflux disease) disorders. Significant is defined as any disease that, in the opinion of the investigator, would put the safety of the participant at risk through study participation or that could affect the efficacy or safety analyses if the disease/condition exacerbated during the study.
• • Unresectable cancer that has not been in complete remission for at least 5 years prior to Visit 1
• • Hospitalization for psychiatric disorder or attempted suicide within 1 year of Visit 1.
• • Known history of drug or alcohol abuse within 12 months of Visit 1 or known abuse at any time during the study.
