Azithromycin in the Management of Patients With Acute Exacerbation of Idiopathic Pulmonary Fibrosis

This randomized controlled trial evaluates the therapeutic role of azithromycin in acute exacerbations of idiopathic pulmonary fibrosis (AE-IPF). Baseline severity classification and stratification were performed using the SCALE-IPF framework (Severity Classification and Lung Evaluation for Prognosis in IPF; locked April 2023) to ensure balanced disease severity across randomized arms. End-of-study analyses included descriptive and stratified phenotyping using the Idiopathic Pulmonary Fibrosis Phenotypes Identification Model (IPIM); locked April 2023). Following a protocol amendment approved in September 2025, the study expanded into a multi-arm therapeutic platform evaluating both azithromycin timing strategies and combination antifibrotic-immunomodulatory therapy in idiopathic pulmonary fibrosis. Additional treatment arms involving pirfenidone with or without azithromycin were incorporated without altering the original randomized comparisons or baseline study framework. Both frameworks were developed within the Assiut University IPF Research Program (2022-2026), a coordinated institutional effort investigating clinical, prognostic, and therapeutic dimensions of IPF. Neither framework altered randomization procedures, treatment allocation, or study endpoints; they were applied to improve standardization, reproducibility, and interpretability of results.
