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

The goal of this interventional study is to compare at-home mobile spirometry to in-clinic spirometry in participants with moderate asthma while taking a long-acting beta agonist (LABA).The main questions it aims to answer are:Do at-home mobile spirometry and in-clinic spirometry assessments show a similar treatment effect (measured changes in FEV1) with the addition of LABA?Is at-home mobile spirometry as accurate as in-clinic spirometry in showing treatment effects (changes in FEV1)?Participants will be asked to:Take standard of care LABA treatment once a dayComplete at-home mobile spirometry testing twice a dayComplete asthma questionnaires twice a dayComplete device use questionnairesWear a wrist device (like a watch) to track physical activity and vital signsVisit the clinic for in-clinic spirometry testing once a week for 8 weeks

Inclusion Criteria:Male or female between 18 years and 65 years of age inclusiveBody mass index (BMI) 18 - 35 mg/m2 inclusiveParticipant with a diagnosis of moderate uncontrolled asthma for a period of at least 2 years prior to screeningParticipant must be using a medium daily dose of inhaled corticosteroids (ICS)Asthma that is not currently using long-acting beta-agonists (LABA), (ICS score of 0.75 or higher)Pre-bronchodilator FEV1 ≥ 60% and ≤100% of the predicted normal values at screeningA documented positive response to the reversibility test at the screening, defined as improvement in FEV1 ≥ 12% and ≥ 200 mL over baseline after 400μg salbutamol pressurized metered-dose inhalers (pMDI)Participant is judged to be in good health based on medical history, physical examination, and vital sign measurementsNon-smokers or ex-smokers with a cumulative tobacco exposure less than 5 pack- years and who have stopped smoking more than 1 year ago (pack-year: number of cigarettes smoked per day multiplied by the number of years of smoking divided by 20)Women of childbearing potential must have a negative urine pregnancy test before enrolling at Baseline Day 1Participant demonstrated ability to perform satisfactory in-clinic and at-home Spirometry according to ATS/ERS standards (Graham 2019), as well as the mobile application to synchronize Spirometry data collection and respond to questionnaires during the Screening coaching/training periodExclusion Criteria: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 monthsOccurrence of asthma exacerbations or respiratory tract infections within 4 weeks prior to ScreeningHistory of substance abuse in the last 6 months, excluding medical or recreational non- inhaled marijuanaCurrently taking other biologics to control asthma symptoms (allergy shots are acceptable)Diagnosis of any other airway/pulmonary disease such as Chronic Obstructive Pulmonary Disease (COPD) as defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines (updated 2013); 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 participantsChronic or acute infection requiring treatment with systemic antibiotics, antivirals, or antifungals within 1 month prior to screeningParticipant has a history of neoplastic disease. Exception (1) participant with an adequately treated basal cell carcinoma or carcinoma in situ of the cervix may participate; (2) participants with other malignancies which have been successfully treated > 10 years prior to screening without evidence of recurrenceParticipants treated with oral or parenteral corticosteroids in the previous 4-6 weeks (12 weeks for parenteral depot corticosteroids) prior to screeningYou 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.
