| 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.
