Comparative Meta-Analysis of the Efficacy of Once-Daily Fluticasone Furoate 100 µG Versus Twice-Daily Fluticasone Propionate 250 µG in Adolescents and Adults with Persistent Asthma

Fluticasone furoate and fluticasone propionate are recommended options for prophylactic maintenance treatment of persistent asthma. Using data from two previous clinical studies (GSK studies: FFA109685/NCT00603278, FFA112059/NCT01159912), this meta-analysis compared change from baseline in clinic visit mean trough forced expiratory volume in 1 s (FEV1) with fluticasone furoate 100 µg once-daily (FF100) versus fluticasone propionate 250 µg twice-daily (FP250) in adolescents and adults with persistent asthma. Using a DerSimonian–Laird random-effects model (primary meta-analysis), there was no statistically significant difference between FF100 and FP250 in change from baseline in trough FEV1 (−1.7 mL [95% CI −80.4, +77.0], p = 0.9664) and FF100 was non-inferior to FP250. Supporting analyses using least squares mean and fixed-effects model approaches produced similar findings. In this analysis, FF100 and FP250 demonstrated a comparable treatment effect on trough FEV1 in patients aged ≥12 years with persistent asthma; however, results interpretation should consider study design and methodological limitations.
