Abstract

PURPOSE: Asthma guidelines recommend stepwise escalation of inhaled corticosteroid/long-acting β(2)-agonist (ICS/LABA) therapy, yet many patients remain uncontrolled. Randomized controlled trials (RCTs) show that single-inhaler triple therapy improves lung function, with varying effects on symptoms and exacerbations. However, highly controlled explanatory RCTs with selective populations may not reflect real-world care. PERFORM evaluated the effectiveness and safety of initiating once-daily fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) ELLIPTA versus usual care non-ELLIPTA ICS/LABA in routine clinical practice. METHODS: PERFORM (GSK219912/NCT06372496) is a randomized, open-label, active-controlled, 52-week, global pragmatic trial including adults (18-75 years) with uncontrolled, infrequently exacerbating asthma, previously untreated or treated with non-ELLIPTA ICS or ICS/LABA in the 3-months pre-randomization. Powered primary and secondary endpoints were change from baseline in trough forced expiratory volume in 1 second (FEV(1)) and asthma control (Asthma Control Questionnaire [ACQ]-7 responder analysis) at Week 24 (W24). Safety was assessed throughout the trial. RESULTS: Overall, 1236 patients (mean age: 48.9 years; 68.6% female) were included in this W24 primary analysis (FF/UMEC/VI: N=619; ICS/LABA: N=617). At baseline mean FEV(1)%predicted was 85.7; mean ACQ-7 score was 2.46. At W24, FF/UMEC/VI statistically significantly improved trough FEV(1) from baseline versus ICS/LABA (least squares mean difference [95% confidence interval]: +68mL [36-99], P< 0.001). FEV(1) improvement from baseline was 178mL (139-217) with FF/UMEC/VI and 110mL (72-149) with ICS/LABA. Odds of a clinically meaningful response in ACQ-7 score (≥0.5-point improvement from baseline) were significantly greater with FF/UMEC/VI versus ICS/LABA (odds ratio [95% confidence interval]: 1.47 [1.13-1.92], P< 0.004); 79.0% of patients achieved a response with FF/UMEC/VI and 71.8% with ICS/LABA. Safety profile to W24 aligned with previous studies. CONCLUSION: This pragmatic RCT demonstrated significant improvements in lung function and asthma control with FF/UMEC/VI versus ICS/LABA in uncontrolled and infrequently exacerbating patients treated in a routine practice setting. These findings further inform the evidence base for optimized use of FF/UMEC/VI.
