This network meta-analysis (NMA) of randomized controlled trials (RCTs) aimed to evaluate the efficacy and safety of pharmacotherapies for progressive fibrotic-interstitial lung diseases (PF-ILDs) to identify optimal treatments. We searched for RCTs on PF-ILD idiopathic pulmonary fibrosis (IPF), connective tissue disease-ILD (CTD-ILD), chronic hypersensitivity pneumonitis (CHP), and pulmonary sarcoidosis pharmacotherapies until 5 June 2025. NMA assessed efficacy forced vital capacity, diffusing capacity of lungs for carbon monoxide, 6-minute-walk distance and safety serious adverse events (SAEs) and all-cause mortality (PROSPERO: CRD42024554475). We included sixty-five studies (13,521 participants) for forty-eight drugs in IPF, ten studies (1,508 participants) for eight drugs in CTD-ILD, four studies (259 participants) for three drugs in CHP, and nine studies (525 participants) for nine drugs in pulmonary sarcoidosis. In IPF, pirfenidone, nintedanib, and IFNγ-1b slowed lung function decline and reduced mortality. In CTD-ILD, pirfenidone, nintedanib, tocilizumab, and cyclophosphamide improved lung function and reduced mortality, with higher SAEs for nintedanib and cyclophosphamide. Pirfenidone and prednisolone benefited CHP, while budesonide improved lung function in pulmonary sarcoidosis. Anti-fibrotic drugs - Pirfenidone and nintedanib effectively slow disease progression and reduce mortality in PF-ILDs. Emerging therapies like IFNγ-1b warrant further research, underscoring the need for large, high-quality RCTs.
