Triple therapy with fluticasone furoate, umeclidinium, and vilanterol resulted in a lower rate of moderate or severe COPD exacerbations than fluticasone furoate-vilanterol or umeclidinium-vilanterol in this population. Triple therapy also resulted in a lower rate of hospitalization due to COPD than umeclidinium-vilanterol. (Funded by GlaxoSmithKline; IMPACT ClinicalTrials.gov number, NCT02164513 .).

Once-daily UMEC/VI 62.5/25 mcg was well tolerated and provided clinically-significant improvements in lung function and symptoms in patients with COPD.

Rationale: The IMPACT (Informing the Pathway of Chronic Obstructive Pulmonary Disease Treatment) trial demonstrated a significant reduction in all-cause mortality (ACM) risk with fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) versus UMEC/VI in patients with chronic obstructive pulmonary disease (COPD) at risk of future exacerbations. Five hundred seventy-four patients were censored in the original analysis owing to incomplete vital status information.Objectives: Report ACM and impact of stepping down therapy, following collection of additional vital status data.Methods: Patients were randomized 2:2:1 to FF/UMEC/VI 100/62.5/25 mg, FF/VI 100/25 mg, or UMEC/VI 62.5/25 mg following a run-in on their COPD therapies. Time to ACM was prespecified. Additional vital status data collection and subsequent analyses were performed post hoc. Measurements and Main Results:We report vital status data for 99.6% of the intention-to-treat population (n = 10,355), documenting 98 (2.36%) deaths on FF/UMEC/VI, 109 (2.64%) on FF/VI, and 66 (3.19%) on UMEC/VI. For FF/UMEC/VI, the hazard ratio for death was 0.72 (95% confidence interval, 0.53-0.99; P = 0.042) versus UMEC/VI and 0.89 (95% confidence interval, 0.67-1.16; P = 0.387) versus FF/VI. Independent adjudication confirmed lower rates of cardiovascular and respiratory death and death associated with the patient's COPD.Conclusions: In this secondary analysis of an efficacy outcome from the IMPACT trial, once-daily single-inhaler FF/UMEC/VI triple therapy reduced the risk of ACM versus UMEC/VI in patients with symptomatic COPD and a history of exacerbations.

FF/VI provides rapid and significant sustained improvement in FEV(1) in subjects with moderate-to-severe COPD, which was not influenced by the dose of FF. These data suggest that FF/VI may offer clinical efficacy in COPD and warrants additional study. GSK study number: HZC112207. ClinicalTrials.gov: NCT01054885.

Once-daily umeclidinium/vilanterol significantly improved lung function in patients with COPD, with quantitatively greater improvements in patients identified as responders to umeclidinium and vilanterol monotherapy than non-responders.

In patients with moderate COPD and heightened cardiovascular risk, FF alone or in combination with VI appears to reduce the rate of FEV decline. Clinical trial registered with www.clinicaltrials.gov (NCT01313676).

Patients with moderate chronic airflow obstruction experienced a reduction in exacerbations with FF/VI compared with placebo, irrespective of a history of exacerbations or baseline FEV. Clinical trial registered with www.clinicaltrials.gov (NCT 01313676; GSK Study number 113782).
