Clinical and economic outcomes in patients with chronic obstructive pulmonary disease initiating maintenance therapy with tiotropium bromide/olodaterol or fluticasone furoate/umeclidinium/vilanterol.

BACKGROUND: Clinical practice guidelines recommend dual long-acting muscarinic antagonists (LAMAs)/long-acting ß2agonists (LABAs) as maintenance therapy in patients with chronic obstructive pulmonary disease (COPD) and dyspnea or exercise intolerance. Escalation to triple therapy (TT) (LAMA/LABA/inhaled corticosteroid) is conditionally recommended for patients with continued exacerbations on dual LAMA/LABA therapy. Despite this guidance, TT use is widespread across COPD severities, which could impact clinical and economic outcomes. OBJECTIVE: To compare COPD exacerbations, pneumonia events, and disease-related and all-cause health care resource utilization and costs (in 2020 US dollars) in patients initiating fixed-dose combinations of either LAMA/LABA (tiotropium/olodaterol [TIO + OLO]) or TT (fluticasone furoate/umeclidinium/vilanterol [FF + UMEC + VI]). METHODS: This retrospective observational study of administrative claims included patients with COPD aged 40 years or older initiating TIO + OLO or FF + UMEC + VI from June 2015 to November 2019. TIO + OLO and FF + UMEC + VI cohorts in the overall and maintenance-naive populations were 1:1 propensity score matched on baseline demographics, comorbidities, COPD medications, health care resource utilization, and costs. Multivariable regression compared clinical and economic outcomes up to 12 months in FF + UMEC + VI vs TIO + OLO postmatched cohorts. RESULTS: After matching, there were 5,658 and 3,025 pairs in the overall and maintenance-naive populations, respectively. In the overall population, the risk of any (moderate or severe) exacerbation was 7% lower in FF + UMEC + VI vs TIO + OLO initiators (adjusted hazard ratio [aHR] = 0.93; 95% CI = 0.86-1.0; P = 0.047). There was no difference in the adjusted risk of any exacerbation in the maintenance-naive population (aHR = 0.99; 95% CI = 0.88-1.10). Pneumonia risk was not statistically different between cohorts in the overall (aHR = 1.12; 95% CI = 0.98-1.27) and maintenance-naive (aHR = 1.13; 95% CI = 0.95-1.36) populations. COPD- and/or pneumonia-related adjusted total annualized costs (95% CI) were significantly greater for FF + UMEC + VI vs TIO + OLO in the overall ($17,633 [16,661-18,604] vs $14,558 [13,709-15,407]; P < 0.001; differences [% of relative increase] = $3,075 [21.1%]) and maintenancenaive ($19,032 [17,466-20,598] vs $15,004 [13,786-16,223]; P < 0.001; $4,028 [26.8%]) populations, with significantly higher pharmacy costs with FF + UMEC + VI (overall: $6,567 [6,503-6,632] vs $4,729 [4,676-4,783]; P < 0.001; $1,838 [38.9%]; maintenance-naive: $6,642 [6,560-6,724] vs $4,750 [4,676-4,825]; P < 0.001; $1,892 [39.8%]). CONCLUSIONS: A lower risk of exacerbation was observed with FF + UMEC + VI vs TIO + OLO in the overall population but not among the maintenance-naive population. Patients with COPD initiating TIO + OLO had lower annualized costs than FF + UMEC + VI initiators in the overall and maintenance-naive populations. Thus, in the maintenance-naive population, initiation with dual LAMA/LABA therapy per practice guidelines can improve real-world economic outcomes.

Healthcare Resource Utilization, Cost and Clinical Outcomes in Patients Diagnosed with COPD Initiating Tiotropium Bromide/Olodaterol versus Fluticasone Furoate/Umeclidinium/Vilanterol Based on Exacerbation History.

Background: ATS and GOLD guidelines recommend treating low-exacerbation risk COPD patients with dual (LAMA/LABA) agents and reserving triple therapy (TT; LAMA/LABA and inhaled corticosteroids [ICS]) for severe cases with higher-exacerbation risk. However, TT often is prescribed across the COPD spectrum. This study compared COPD exacerbations, pneumonia diagnosis, healthcare resource utilization, and costs for patients initiating tiotropium bromide/olodaterol (TIO/OLO) and a TT, fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), stratified by exacerbation history. Methods: COPD patients who initiated TIO/OLO or FF/UMEC/VI between 06/01/2015-11/30/2019 (index date=first pharmacy fill-date with ≥30 consecutive treatment days) were identified from the Optum Research Database. Patients were ≥40 years old and continuously enrolled for 12 months during the baseline period and ≥30 days during follow-up. Patients were stratified into GOLD A/B (0-1 baseline non-hospitalized exacerbation), No exacerbation (subset of GOLD A/B), and GOLD C/D (≥2 non-hospitalized and/or ≥1 hospitalized baseline exacerbation). Baseline characteristics were balanced with propensity score matching (1:1). Adjusted risks of exacerbation, pneumonia diagnosis, and COPD and/or pneumonia-related utilization and costs were evaluated. Results: Adjusted exacerbation risk was similar in GOLD A/B and No exacerbation subgroups, and lower in GOLD C/D for FF/UMEC/VI versus TIO/OLO initiators (hazard ratio: 0.87; 95% CI: 0.78, 0.98, p=0.020). Adjusted pneumonia risk was similar between cohorts across the GOLD subgroups. Adjusted COPD and/or pneumonia-related population annualized pharmacy costs were significantly higher for FF/UMEC/VI versus TIO/OLO initiators across subgroups, p<0.001. Adjusted COPD and/or pneumonia-related population annualized total healthcare costs were significantly higher for FF/UMEC/VI versus TIO/OLO initiators in the GOLD A/B and No exacerbation, subgroups, p<0.001 (cost ratio [95% CI]: 1.25 [1.13, 1.38] and 1.21 [1.09, 1.36], respectively), but similar in the GOLD C/D subgroup. Conclusion: These real-world results support ATS and GOLD recommendations for treating low-exacerbation risk COPD patients with dual bronchodilators and TT for more severe, higher-exacerbation risk COPD patients.
