The primary objective of the study is to evaluate the efficacy of dupilumab on lung function in participants with Allergic Bronchopulmonary Aspergillosis (ABPA). The secondary objectives of the study are: * To evaluate the effects of dupilumab on exacerbations in participants with ABPA * To evaluate the effects of dupilumab on ABPA-related exacerbations * To evaluate the effects of dupilumab on hospitalization/emergency department (ED)/urgent care visits in participants with ABPA * To evaluate the effects of dupilumab on asthma control in participants with ABPA * To evaluate the effects of dupilumab on health-related quality of life (HRQoL) in participants with ABPA * To evaluate the effects of dupilumab on serum total immunoglobulin E (IgE) and Aspergillus-specific IgE concentrations * To evaluate the effects of dupilumab on Fractional exhaled Nitric Oxide (FeNO) levels * To evaluate safety and tolerability of dupilumab in participants with ABPA * To evaluate dupilumab concentrations in serum and the incidence of anti-dupilumab antibodies in participants with ABPA
