NICEFIT—A Prospective, Non-Interventional, and Multicentric Study for the Management of Idiopathic Pulmonary Fibrosis with Antifibrotic Therapy in Taiwan

Abstract

Idiopathic pulmonary fibrosis (IPF) causes progressive lung fibrosis with subsequent fatality and has limited treatment options. NICEFIT is the first Taiwan-based prospective, observational, and non-interventional registry for IPF progression under routine clinical practice in Taiwan. Data on 101 patients (aged 74.6 ± 9.1 years and 83.2% men) with IPF were collected over 2 years (2018−2020) from medical centers in Taiwan at baseline, 1 month, and subsequent 3-month intervals. Treated patients (n = 88) received the antifibrotics nintedanib or pirfenidone, compared with the untreated group (n = 13). The 2-year assessment revealed overall preserved lung functionality in the treated patients, with insignificant changes from baseline for percent predicted forced vital capacity or FVC (±1.7%). The presence of respiratory comorbidities significantly increased the risk of both AE and death (with or without AE) over the full study duration. Furthermore, the decline of predicted FVC significantly increased with the risk of acute exacerbations (AE) in the second year. Overall, antifibrotic medication was beneficial in stalling IPF progression, reducing AEs, and delaying mortality in the treated cohort, despite their lower baseline lung functions. Further, no new safety concerns over antifibrotic treatments were observed for the Taiwanese population.
