INTRODUCTION: Excessive mucus secretion is pivotal in chronic obstructive pulmonary disease (COPD) pathophysiology, particularly in chronic bronchitis phenotypes. Cystic fibrosis transmembrane conductance regulator (CFTR) has been implicated in COPD-related hypersecretion with acquired dysfunction, and emerged as a therapeutic target. However, the clinical efficacy of CFTR-potentiators in COPD remains controversial.
METHODS: We searched PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal (CSTJ), and Wanfang Database to retrieve eligible studies published before 28 May 2024.
RESULTS: A total of 1172 COPD patients were included, meta-analysis showed that CFTR-potentiators significantly increased forced expiratory volume in 1 s (FEV1) and decreased sweat chloride and fibrinogen levels, with moderate-to-high quality evidence. However, no significant effects were observed on the percentage of detected FEV1 to predicted FEV1 (FEV1% predicted), forced vital capacity (FVC), COPD assessment test (CAT) score, St. George's Respiratory Questionnaire (SGRQ) score, or acute exacerbation times, with low-to-moderate quality evidence.
CONCLUSION: Our meta-analysis demonstrated CFTR-potentiators' potential efficacy in increasing FEV1, decreasing sweat chloride and fibrinogen levels, despite limited impacts on FEV1% predicted, FVC, CAT score, SGRQ score, and acute exacerbations, underscoring the necessity for future research to evaluate its effects on mucus hypersecretion, acute exacerbations, hospitalizations, and mortality in COPD management.
