Objectives

Narrative objectives1

The aim of this study is to evaluate the effect of adjunctive Aerobika use on sputum symptoms, as assessed by the CASA-Q sputum domain, in patients with asthma and allergic bronchopulmonary mycosis (ABPM).

Assessment

Primary outcomes

Change from baseline to Week 12 in the CASA-Q sputum symptom domain score

Key secondary outcomes

Comparison between baseline (immediately before study initiation) and Week 12 for the following parameters:
-CASA-Q cough symptom domain score
-Patient-reported ease of sputum expectoration assessed using a visual analog scale (VAS)
(0 mm = unable to expectorate sputum at all; 100 mm = able to expectorate sputum very easily)
-Asthma control and quality of life assessed by the Mini Asthma Quality of Life Questionnaire (MiniAQLQ)
-Hematological parameters: red blood cell count, hemoglobin, reticulocyte count, white blood cell count, platelet count, lymphocyte count, neutrophil count, and eosinophil count
-Pulmonary function: FEV1, FEF25-75, and FVC
-Airway inflammation marker: fractional exhaled nitric oxide (FeNO)
-Respiratory impedance measured by the forced oscillation technique (FOT; MostGraph): R5, R20, R5-R20, X5, and Fres
-Type 2 inflammatory biomarkers
-Urinary leukotriene E4 (LTE4) (measured in a research laboratory; not covered by health insurance)
-Serum and urinary eosinophil-derived neurotoxin (EDN) (measured in a research laboratory; not covered by health insurance)
-Peripheral blood eosinophil count
-Between-group comparison: comparison of the change in CASA-Q scores between the Aerobika use group and the non-use group
-Incidence of adverse events throughout the observation period
-Number of asthma exacerbations and ABPM relapses throughout the observation period

Key inclusion criteria

Inclusion Criteria
1. Outpatients aged 18 years or older who have been receiving standard treatment for asthma or allergic bronchopulmonary mycosis (ABPM) at our institution.
(The diagnosis of ABPM will be based on Reference 4.)
2. Patients who have not experienced an asthma exacerbation or recurrence of ABPM within 24 weeks prior to obtaining informed consent.
3. Patients whose treatment for the underlying disease has remained unchanged for at least 12 weeks prior to obtaining informed consent, whose disease condition is stable, and who continue to have chronic sputum symptoms.
* Chronic sputum symptoms are defined as sputum symptoms persisting for at least 12 weeks as confirmed by interview. In addition, a CASA-Q sputum symptom domain score of 80 or less must have been confirmed on two occasions separated by at least 4 weeks during the screening period and at study entry.
** Rationale for the cutoff value of 80: In patients with severe asthma eligible for biologic therapy, 79% had a CASA-Q sputum symptom domain score of 80 or less, whereas only 42% had a score of 60 or less (Reference 6). To include a broader range of patients with asthma, a cutoff value of 80 was adopted in this study.
4. Patients who are considered by the treating physician to have no contraindication to continued use of Aerobika.
5. Patients who have provided written informed consent for the use of Aerobika.

Key exclusion criteria

Exclusion Criteria
1. Patients who are unable to understand or properly use the Aerobika device.
2. Patients who have experienced an asthma exacerbation or recurrence of ABPM within the previous 24 weeks.
3. Patients currently using other airway clearance or sputum clearance devices.
4. Patients with comorbid conditions that may affect study assessments, including autoimmune diseases and heart failure.
5. Patients who are pregnant or have untreated pneumothorax, progressive hemoptysis, elevated intracranial pressure, hemodynamic instability, or other conditions in which Aerobika use may be inappropriate.
6. Patients deemed unsuitable for participation in the study by the principal investigator or sub-investigators.
