Study Comparing At-Home Mobile Spirometry to In-Clinic in Moderate Asthma Participants Taking Long-Acting Beta Agonist

Prior treatment

• History of life-threatening asthma, defined as an asthma episode that required intubation and/or was associated with hypercapnia, respiratory arrest and/or hypoxic seizures or hospitalization (including ER visits) for the treatment of asthma within 3 months prior to screening, or have been hospitalized or have attended the ER for asthma more than twice in prior 6 months
• Occurrence of asthma exacerbations or respiratory tract infections within 4 weeks prior to Screening
• Currently taking other biologics to control asthma symptoms (allergy shots are acceptable)
• Chronic or acute infection requiring treatment with systemic antibiotics, antivirals, or antifungals within 1 month prior to screening
• Participant has a history of neoplastic disease. Exceptions: Participants with (1) an adequately treated basal or squamous cell carcinoma or carcinoma in situ of the cervix; (2) localized or regional prostate cancer; other malignancies which have been successfully treated \> 5 years prior to screening without evidence of recurrence may participate
• Participants treated with oral or parenteral corticosteroids in the previous 4 weeks prior to screening
• You may not be able to participate in this study if you have been in another investigational drug study for 30 days prior to this study unless approval is given from the Sponsor. Additionally, you cannot be involved in another investigational drug study during your participation in this study.

Other illness

• History of substance abuse in the last 6 months, excluding medical or recreational non- inhaled marijuana
• Diagnosis of any other airway/pulmonary disease such as Chronic Obstructive Pulmonary Disease (COPD) as defined by the current Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines; or other lung diseases (e.g., emphysema, idiopathic pulmonary fibrosis, Churg-Strauss syndrome, allergic bronchopulmonary aspergillosis cystic fibrosis, bronchiectasis or alpha-1 antitrypsin deficiency or restrictive lung disease)
• Clinically unstable participants or history of non-compliance as assessed by the PI

• Individuals 18 years or older
• Body mass index (BMI) 18 - 40 mg/m2 inclusive
• Participant with a diagnosis of moderate uncontrolled asthma
• Participant must be using a medium to high daily dose of inhaled corticosteroids (ICS) for a minimum of 6 weeks prior to screening
• Asthma that is not currently using long-acting beta-agonists (LABA) or log-acting muscarinic antagonist (LAMA) (ACQ score of 0.75 or higher) Note: A 2-week LABA/LAMA washout period is allowed prior to screening
• Pre-bronchodilator FEV1 ≥ 60% and ≤100% of the predicted normal values at screening
• A documented positive response to the reversibility test at screening, defined as improvement in FEV1 ≥ 12% and ≥ 200 mL over baseline after a Short Acting Beta Agonist (SABA) standard of care dose. Documented historical reversibility of up to 6 weeks is allowed.
• Participant is judged to be in good health based on medical history, physical examination, and vital sign measurements
• Non-smokers or ex-smokers (including vape or inhaled cannabis) who have stopped smoking more than 1 year ago
• Women of childbearing potential must have a negative urine pregnancy test before enrolling at Baseline Day 1
• Participant demonstrated ability to perform satisfactory in-clinic and at-home Spirometry according to ATS/ERS standards, as well as the mobile application to synchronize Spirometry data collection and respond to questionnaires during the Screening coaching/training period
