fluticasone and olodaterol

Tiotropium + olodaterol has demonstrated improvements beyond lung function benefits in a large Phase III clinical program as a once-daily maintenance treatment for COPD and may be a potential option for the initiation of maintenance treatment in COPD. Despite guideline recommendations that combined long-acting β2-agonists and inhaled corticosteroids should only be used in individuals at high risk of exacerbation, there is substantial use in individuals at lower risk. This raises the question of the comparative effectiveness of this combination as maintenance treatment in this group compared to other combination regimens.. The study aimed to assess the effect on lung function of once-daily tiotropium + olodaterol versus twice-daily salmeterol + fluticasone propionate in all participants with Global initiative for chronic Obstructive Lung Disease 2 or 3 (moderate to severe) COPD.. This was a randomized, double-blind, double-dummy, four-treatment, complete crossover study in which participants received once-daily tiotropium + olodaterol (5/5 µg and 2.5/5 µg) via Respimat(®) and twice-daily salmeterol + fluticasone propionate (50/500 µg and 50/250 µg) via Accuhaler(®) for 6 weeks. The primary end point was change in forced expiratory volume in 1 second (FEV1) area under the curve from 0 hour to 12 hours (AUC0-12) relative to the baseline after 6 weeks.. Tiotropium + olodaterol 5/5 µg and 2.5/5 µg demonstrated statistically significant improvements in FEV1 AUC0-12 compared to salmeterol + fluticasone propionate (improvements from baseline were 317 mL and 295 mL with tiotropium + olodaterol 5/5 µg and 2.5/5 µg, and 188 mL and 192 mL with salmeterol + fluticasone propionate 50/500 µg and 50/250 µg, respectively). Tiotropium + olodaterol was superior to salmeterol + fluticasone propionate in lung function secondary end points, including FEV1 area under the curve from 0 hour to 24 hours (AUC0-24).. Once-daily tiotropium + olodaterol in participants with moderate-to-severe COPD provided superior lung function improvements to twice-daily salmeterol + fluticasone propionate. Dual bronchodilation can be considered to optimize lung function in individuals requiring maintenance treatment for COPD.

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.. 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.. 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.. 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.

Human lung mast cells (HLMCs) play a central role in asthma pathogenesis through their relocation to the airway smooth muscle (ASM) bundles. β2 adrenoceptor (β2-AR)-agonists are used to relieve bronchoconstriction in asthma, but may reduce asthma control, particularly when used as monotherapy. We hypothesized that HLMC and human ASM cell (HASMC) responsiveness to β2-AR agonists would be attenuated when HLMCs are in contact with HASMCs. Cells were cultured in the presence of the short-acting β2-agonist albuterol, and the long-acting β2-agonists formoterol and olodaterol. Constitutive and FcεRI-dependent HLMC histamine release, HASMC contraction, and β2-AR phosphorylation at Tyr(350) were assessed. Constitutive HLMC histamine release was increased in HLMC-HASMC coculture and this was enhanced by β2-AR agonists. Inhibition of FcεRI-dependent HLMC mediator release by β2-agonists was greatly reduced in HLMC-HASMC coculture. These effects were reversed by neutralization of stem cell factor (SCF) or cell adhesion molecule 1 (CADM1). β2-AR agonists did not prevent HASMC contraction when HLMCs were present, but this was reversed by fluticasone. β2-AR phosphorylation at Tyr(350) occurred within 5 min in both HLMCs and HASMCs when the cells were cocultured, and was inhibited by neutralizing SCF or CADM1. HLMC interactions with HASMCs via CADM1 and Kit inhibit the potentially beneficial effects of β2-AR agonists on these cells via phosphorylation of the β2-AR. These results may explain the potentially adverse effects of β2-ARs agonists when used for asthma therapy. Targeting SCF and CADM1 may enhance β2-AR efficacy, particularly in corticosteroid-resistant patients.
