Objectives
Narrative objectives1
The standard treatment for acute allergic bronchopulmonary aspergillosis (ABPA) consisting of 4-6 months of oral corticosteroid therapy results in high treatment failure rate. On the other hand, the high cumulative dose of corticosteroid is associated with a substantial risk of adverse events among mild cases who achieve successful treatment. In this study, acute ABPA will be stratified into refractory and mild cases using the difficult-to-treat ABPA score developed by the investigators. The primary objective is to evaluate the efficacy and safety of short-course corticosteroid monotherapy in mild cases through a multicenter randomized controlled trial.

Assessment
Primary outcomes
Time to treatment failure within 40 weeks after initiation of therapy
Key secondary outcomes
Key Secondary Endpoints
1. Time to exacerbation of ABPA within 92 weeks after initiation of therapy
2. Safety within 92 weeks after initiation of therapy
Other Secondary Endpoints
1. Longitudinal changes in asthma control (ACQ)
2. Changes in asthma-related quality of life (miniAQLQ)
3. Longitudinal changes in serum total IgE levels, peripheral blood eosinophil counts, and Aspergillus-specific IgE and IgG
4. Time to improvement in chest imaging findings
5. Changes in pulmonary function (FEV1, FeNO)
6. Post-treatment exacerbation of ABPA within 1.5 years after completion of therapy and risk factors associated with exacerbation
Exploratory Secondary Endpoints
1. Changes in the plasma proteome before and after treatment and their association with post-treatment ABPA exacerbation
2. Changes in peripheral blood immune cell populations before and after treatment and their association with post-treatment ABPA exacerbation

Key inclusion criteria
1. Age 18 years or older.
2. Patients receiving treatment for asthma with at least a medium dose of inhaled corticosteroids plus one or more additional long-term controller medications.
3. Fulfillment of 6 or more items of the Asano's diagnostic criteria for ABPA (J Allergy Clin Immunol. 2021;147:1261).
4. Serum Aspergillus fumigatus-specific IgE antibody level 0.35 UA/mL or higher.
5. At the time of initial onset or exacerbation of ABPA.
6. Written informed consent obtained after sufficient explanation, based on the participant's free will.

8. Refractory ABPA score (Allergy. 2025;80:2531) is 1 or less.
Key exclusion criteria
1. Systemic corticosteroid administration within the past 1 month.
2. Treatment with immunosuppressive agents other than corticosteroids, antifungal agents (oral or intravenous), or biologics within the past 6 months.
3. Comorbidities precluding oral corticosteroid use (e.g., uncontrolled diabetes mellitus, glaucoma, active peptic ulcer disease, or active infection).
4. History of allergic reaction to mepolizumab (Nucala) or tezepelumab (Tezspire).
5. Currently undergoing treatment for malignancy, or history of treatment within the past year.
6. Severe cardiac disorders (e.g., heart failure, arrhythmia).
7. Any other condition deemed inappropriate by the principal investigator or study physician.
