    Background: IMPACT is a randomized, multicenter study (52 weeks) comparing the efficacy and safety of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) vs. FF/VI and UMEC/VI in patients ≥ 40 years of age with symptomatic COPD and a history of exacerbations (N = 10,355). For the primary endpoint, FF/UMEC/VI demonstrated a significant reduction in moderate (mod)/severe (sev) exacerbations vs. FF/VI and UMEC/VI (NEJM 2018; 378: 18).

    Objectives: Evaluate the overall exacerbation benefit of FF/UMEC/VI

    Methods: Sensitivity analyses were examined for the primary endpoint of annual rate mod/severe exacerbations and time-to-first mod/severe exacerbation ([Table 1]). All exacerbation endpoints analyzed (ITT population) are listed in [Table 2].

    bold = p < 0.05; Abx = antibiotic; CI = confidence interval; trt = treatment; (95% Confidence Interval); *with or without antibiotics; **with or without corticosteroids; ***risk of the first and each subsequent exacerbation. The annual rate of exac was analyzed using a generalized linear model and TTF exac was analyzed using Coxʼs proportional hazards model. Both models were adjusted for the following: treatment group, gender, exac history, smoking status, baseline % predicted FEV1 and geographical region.

    12.3% (6.3, 18.0)

    7.6% (− 0.3, 14.9)

    Results: Results of the sensitivity analyses are consistent with the primary analysis ([Table 1]). FF/UMEC/VI vs. FF/VI and UMEC/VI showed statistically significant reduction in rate and risk of exacerbations across the majority of endpoints including steroid and antibiotic-treated events ([Table 2]).

    Conclusions: FF/UMEC/VI showed significant benefit across a range of exacerbation endpoints vs. FF/VI and UMEC/VI. This underscores the robust efficacy profile of FF/UMEC/VI and supports its role in the treatment of symptomatic patients with a history of exacerbations.
