Abstract

Rationale:

Randomized data comparing triple therapy with dual inhaled corticosteroid (ICS)/long-acting β2-agonist (LABA) therapy in patients with chronic obstructive pulmonary disease (COPD) are limited.

Objectives:

We compared the effects of once-daily triple therapy on lung function and health-related quality of life with twice-daily ICS/LABA therapy in patients with COPD.

Methods:

The FULFIL (Lung Function and Quality of Life Assessment in Chronic Obstructive Pulmonary Disease with Closed Triple Therapy) trial was a randomized, double-blind, double-dummy study comparing 24 weeks of once-daily triple therapy (fluticasone furoate/umeclidinium/vilanterol 100 μg/62.5 μg/25 μg; ELLIPTA inhaler) with twice-daily ICS/LABA therapy (budesonide/formoterol 400 μg/12 μg; Turbuhaler). A patient subgroup remained on blinded treatment for up to 52 weeks. Co-primary endpoints were change from baseline in trough FEV1 and in St. George’s Respiratory Questionnaire (SGRQ) total score at Week 24.

Measurements and Main Results:

In the intent-to-treat population (n = 1,810) at Week 24 for triple therapy (n = 911) and ICS/LABA therapy (n = 899), mean changes from baseline in FEV1 were 142 ml (95% confidence interval [CI], 126 to 158) and −29 ml (95% CI, −46 to −13), respectively, and mean changes from baseline in SGRQ scores were −6.6 units (95% CI, −7.4 to −5.7) and −4.3 units (95% CI, −5.2 to −3.4), respectively. For both endpoints, the between-group differences were statistically significant (P < 0.001). There was a statistically significant reduction in moderate/severe exacerbation rate with triple therapy versus dual ICS/LABA therapy (35% reduction; 95% CI, 14-51; P = 0.002). The safety profile of triple therapy reflected the known profiles of the components.

Conclusions:

These results support the benefits of single-inhaler triple therapy compared with ICS/LABA therapy in patients with advanced COPD.

Conclusions:

Clinical trial registered with www.clinicaltrials.gov (NCT02345161).
