Details and patient eligibility


This is a US study comparing the efficacy and safety of BDA MDI [Budesonide/Albuterol Sulfate (BDA) metered dose inhaler (MDI)] with AS [Albuterol Sulfate] MDI, both are administered as needed for up to 12 months.

Full description

This is a phase IIIb, multicenter, randomized, double-blind, parallel-group, event-driven, variable-length, decentralized study.

Participants from around 40 to 50 centers located in the US will be screened and randomized 1:1 to receive one of the following two treatments to be used as needed: BDA MDI (160/180 μg) and AS MDI (180 μg). Participants 12 years of age and older with asthma will be recruited with all visits conducted virtually.

Eligible participants must be using as-needed SABA (Short -acting β2agonist) alone, or as-needed SABA on a background of either low-dose ICS (Inhaled corticosteroid) or a LTRA (Leukotriene receptor agonist), for the treatment of asthma.

Participants will be stratified by pre-study asthma medication (SABA only, low-dose ICS + SABA and LTRA + SABA) and number of prior severe exacerbations (0, ≥1) in the 12 months prior to the Screening visit.

No Healthy Volunteers

Inclusion criteria

  1. Participant must be ≥12 years of age, at the time of signing the electronic informed consent form (eICF). For participants from 12 years of age to age of majority, their parents/legal guardian must provide signed consent, as appropriate, and participants will sign an assent form.
  2. Diagnosis of asthma by a prescribing healthcare professional. Protocol-specified documentation of asthma diagnosis is required to confirm diagnosis of asthma.
  3. Participants actively using SABA alone or SABA on a background of either low-dose ICS or LTRA.
  4. Self-reported use of a SABA on ≥2 occasions, in response to symptoms (ie, not for exercise prophylaxis only), in the previous 2 weeks prior to enrollment.
  5. An Asthma Impairment and Risk Questionnaire (AIRQ) score of ≥2 at Screening (Visit1/re-screen) and Randomisation (Randomization (Visit2) where applicable. Note, where screening Visit1/re-screen and randomization occur on the same day, AIRQ will only be completed once.
  6. Females of child-bearing potential must have a negative pregnancy test prior to randomization and agree to use an acceptable method of contraception throughout the study.
  7. Male participants who are in heterosexual relationships must be surgically sterile or agree to use an effective method of contraception (condom) if the female partner does not use contraception from the date the eICF is signed until 2 weeks after their last dose.

Exclusion criteria

  1. Any evidence of significant lung disease other than asthma, such as chronic obstructive pulmonary disease, emphysema, idiopathic pulmonary fibrosis, sarcoidosis etc or any other significant disease (like malignancies or severe chronic diseases) that by Investigator judgment would interfere with the participant being able to comply with study procedures or complete the study.
  2. Hospitalization due to asthma in the 3 months prior to enrollment or self-reported admission to the Intensive Care Unit with life-threatening asthma at any time in the past
  3. Self-reported use of inhaled Long-Acting Beta-Agonists (LABA), theophylline, inhaled anticholinergic agent, cromone or medium/high dose ICS daily, as regular maintenance asthma therapy in the 3 months prior to enrollment
  4. Self-reported use of systemic corticosteroids (SCS) for the treatment of asthma and any other condition in the 6 weeks prior to enrollment
  5. Participants with a home supply of oral corticosteroids (OCS) to be used in the case of an asthma exacerbation or any other condition that could require a course of OCS, who are not willing to commit to the treating physician to stop using this medication for the duration of the study.
  6. Receipt of any marketed (eg, omalizumab, mepolizumab, reslizumab, benralizumab, dupilumab, tezepelumab) or investigational biologic for the treatment of asthma at any time in the past
  7. Receipt of bronchothermoplasty
  8. Use of a SABA prophylactically primarily to prevent exercise induced bronchospasm (EIB) and not to treat symptoms
  9. Currently receiving systemic treatment with potent cytochrome P3A4 inhibitors (eg, ketoconazole, itraconazole, and ritonavir)
  10. Judgment by the Investigator that the participant should not participate in the study if the participant is unlikely to comply with study procedures, restrictions, and requirements.
  11. Previous screening, enrollment or randomization in the present study.
  12. For females only - currently pregnant (confirmed with positive pregnancy test) or breastfeeding.
  13. Participants without access to a smartphone or the internet.
