Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Achieving Meaningful Asthma Improvement at the End of 12-Week Treatment Period | Baseline to Week 12 | Meaningful asthma improvement was defined as an Asthma Control Test (ACT) score of at least 20 at the end of the 12-week treatment period or an increase of at least 3 units on the ACT score from baseline at the end of the 12-week treatment period. The ACT was a simple, participant-completed tool used to assess overall asthma control. The 5 items included in the ACT assess daytime and night-time asthma symptoms, use of reliever medication, and impact of asthma on daily functioning. Each item in the ACT was scored on a 5-point scale, with a summation of all items providing scores ranging from 5 to 25. The scores span the continuum of poor control of asthma (score of 5) to complete control of asthma (score of 25), with a cutoff score of 19 and below indicating participants with poorly controlled asthma. |

Number of Increased Doses of Inhaled Medication
Number of participants who received increased dose of inhaled medication during the 12-week treatment period are reported.
Time frame: Baseline up to Week 12
Population: mITT analysis set included all randomized participants who received at least 1 dose of IMP (IMP is albuterol eMDPI for the DS group and standard-of-care albuterol-administering rescue medication for the CC group) and at least 1 postbaseline assessment on any of the study endpoints. Here, 'overall number of participants analyzed' = participants evaluable for this outcome measure.

Number of Participants With Adverse Events (AEs)
An AE was defined as any untoward medical occurrence that develops or worsens in severity during the conduct of a clinical study and does not necessarily have a causal relationship to the study drug. SAEs included death, a life-threatening adverse event, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, or an important medical event that jeopardized the participant and required medical intervention to prevent 1 of the outcomes listed in this definition. A summary of serious and non-serious AEs regardless of causality is located in 'Reported Adverse Events module'. Number of participants with any AEs, treatment-related AEs, and device-related AEs has been reported.
Time frame: Baseline up to Week 14
Population: Safety analysis set included all participants in the DS group who received at least 1 dose of IMP and all participants in the CC group.
| Arm | Measure | Group | Value (COUNT_OF_PARTICIPANTS) |
|---|---|---|---|
| Concurrent Control (CC) | Number of Participants With Adverse Events (AEs) | Any AEs | 26 Participants |

System Usability Scale (SUS) Overall Score
The SUS was used to explore device acceptability and usability for participants in the DS group. It covered a variety of aspects of system usability, such as the need for support, training, and complexity, and thus giving a global view of subjective assessments of usability. It was a 10-question tool (with five response options; from 1=strongly disagree to 5=strongly agree) that provided a composite measure, ranging from 0 to 100, of the overall usability of the system being studied. Higher scores represent better usability level for the tool.
Time frame: Week 12
Population: mITT analysis set included all randomized participants who received at least 1 dose of IMP (IMP is albuterol eMDPI for the DS group and standard-of-care albuterol-administering rescue medication for the CC group) and at least 1 postbaseline assessment on any of the study endpoints. Here, 'overall number of participants analyzed' = participants evaluable for this outcome measure.
