RESUMO
OBJECTIVE: To evaluate the real-world impact of mepolizumab on the incidence of asthma exacerbations, oral corticosteroid (OCS) use and asthma exacerbation-related costs in patients with high-burden severe asthma. METHODS: This was a retrospective study of the MarketScan Commercial and Medicare Databases in patients with high-burden severe asthma (≥80th percentile of total healthcare expenditure and/or significant comorbidity burden). Patients were ≥12 years of age upon mepolizumab initiation (index date November 1, 2015-December 31, 2018) and had ≥2 mepolizumab administrations during the 6 months post-index. Asthma exacerbation frequency (primary outcome), use of OCS (secondary outcome), and asthma exacerbation-related costs (exploratory outcome) were assessed during the 12 months pre-index (baseline) and post-index (follow-up). RESULTS: In total, 281 patients were analyzed. Mepolizumab significantly reduced the proportion of patients with any asthma exacerbation (P < 0.001) or exacerbations requiring hospitalization (P = 0.004) in the follow-up versus baseline period. The mean number of exacerbations decreased from 2.5 to 1.5 events/patient/year (relative reduction: 40.0%; P < 0.001). The proportion of patients with ≥1 OCS claim also decreased significantly from 94.0% to 81.9% (relative reduction: 12.9%; P < 0.001), corresponding to a decrease from 6.6 to 4.7 claims/person/year (P < 0.001). Of the 264 patients with ≥1 OCS claim during baseline, 191 (72.3%) showed a decrease in mean daily OCS use by ≥50% in 117 patients (61.3%). Total asthma exacerbation-related costs were significantly lower after mepolizumab was initiated (P < 0.001). CONCLUSIONS: Mepolizumab reduced exacerbation frequency, OCS use and asthma exacerbation-related costs in patients with high-cost severe asthma. Mepolizumab provides real-world benefits to patients, healthcare systems and payers.

BACKGROUND/OBJECTIVE: Although the high disease burden associated with eosinophilic granulomatosis with polyangiitis (EGPA) has been established, the disease burden in patients initiating mepolizumab in real-world practice is poorly understood. This study aimed to assess characteristics and burden of real-world patients with EGPA initiating mepolizumab. METHODS: This was a database study (GSK study ID: 214156) of US patients (≥12 years old) with EGPA and ≥1 mepolizumab claim (index date) identified from the Merative MarketScan Commercial and Medicare Supplemental Databases (November 1, 2015, to March 31, 2020). Outcomes assessed in the 12-month baseline period before index (inclusive) included patient characteristics, treatment use, EGPA relapses, asthma exacerbations, health care resource utilization, and costs. RESULTS: In the 103 patients included (mean age, 51.1 years; 63.1% female), the most common manifestations were asthma (89.3%), chronic sinusitis (57.3%), and allergic rhinitis (43.7%). In total, 91.3% of patients had ≥1 oral corticosteroid (OCS) claim (median dose, 7.4 mg/d prednisone-equivalent), 45.6% were chronic OCS users (≥10 mg/d during the 90 days preindex), 99.0% had ≥1 EGPA-related relapse, and 62.1% ≥1 asthma exacerbation. During the baseline period, 26.2% and 97.1% of patients had EGPA-related inpatient admissions and office visits, respectively. Median all-cause total health care costs per patient were $33,298, with total outpatient costs ($16,452) representing the largest driver. CONCLUSIONS: Before initiating mepolizumab, a substantial real-world EGPA disease burden is evident for patients, with resulting impact on health care systems, and indicative of unmet medical needs. Mepolizumab treatment, with a demonstrated positive clinical benefit-risk profile may represent a useful treatment option for reducing EGPA disease burden.

BACKGROUND: Mepolizumab is a humanized anti-interleukin-5, monoclonal antibody approved for the treatment of patients with severe eosinophilic asthma (SEA). There is limited evidence that mepolizumab can reduce inhaled corticosteroid (ICS) use in these patients. OBJECTIVE: To investigate changes in ICS use and clinical outcomes in patients with SEA who initiated mepolizumab treatment. METHODS: This retrospective cohort study (GlaxoSmithKline identification: 212695/HO-20-19951) used administrative claims data from the IBM Watson Health MarketScan Database (identification period: November 2015 to March 2018). Eligible patients had SEA and were receiving high-dose ICS and mepolizumab. Use of ICS, oral corticosteroid (OCS), and short-acting ß2-agonist and exacerbation frequency were analyzed quarterly during the 12-month follow-up period after mepolizumab initiation. RESULTS: In total, 351 patients were included. The proportion of patients using high-dose ICS decreased in quarters 1 to 4 after mepolizumab initiation (79.8%, 74.6%, 68.9%, 65.5%, respectively); 49.0% of patients reduced or discontinued ICS for one or more quarter. Comparing patients who discontinued ICS vs those who remained on high-dose ICS, a lower proportion had chronic OCS use (3.4%-9.2% vs 13.9%-16.8%) and OCS burst use (15.4%-20.8% vs 19.7%-26.1%) in quarters 1 to 4; similarly in quarters 3 and 4, a lower proportion of patients had exacerbations (16.9% and 20.3% vs 27.2% and 27.7%) and short-acting ß2-agonist claims (35.4% and 39.2% vs 43.3% and 49.0%, respectively). CONCLUSION: In patients with SEA on high-dose ICS, a reduction in both ICS and OCS use was observed after initiating mepolizumab. These findings have important implications for clinical outcomes and follow-up care in this patient population.

OBJECTIVE: To assess patient- and physician-reported reasons for discontinuing biologic therapy among patients with severe asthma from a real-world US cohort. METHODS: This retrospective analysis surveyed US physicians and their patients with severe asthma who were receiving/had previously received biologic therapy between August and December 2019. Physicians managing ≥3 patients with asthma per month completed surveys on disease management, demographics, exacerbation history, and biologic adherence for eligible patients. Patients could voluntarily complete a questionnaire, providing perceptions of their disease and treatment. RESULTS: 117 physicians completed case reports for 285 patients; 85 patients had discontinued biologic therapy. Physicians (n = 85) and patients (n = 64) reported patient request (28.2% and 46.9%), shortness of breath (45.9% and 23.4%), other chronic respiratory symptoms (29.4% and 10.9%), cost/reimbursement (17.7%/9.4% and 20.3%/7.8%), and exacerbations (25.9% and 10.9%) among the main reasons for biologic discontinuation. Patients who continued biologic therapy were older (mean age 47.6 years) than those who discontinued (43.8 years), and were more likely to have ≥2 exacerbations in the previous year (52.5% vs 35.3%), allergic rhinitis (70.0% vs 62.4%), or chronic rhinosinusitis (30.0% vs 12.9%). Side effects were cited as reasons by only 15.3% and 7.8% of physicians and patients, respectively. CONCLUSIONS: The most common reasons given for discontinuation of biologic therapy were lack of symptom control, exacerbations, cost, and patient request. These data highlight the complexity of care for this patient group and the need for ongoing, regular assessment of common challenges to biologic continuation and reasons for discontinuation, including both clinical and non-clinical factors.

BACKGROUND: Patients with severe asthma frequently have associated comorbidities, which can compound existing symptoms, complicating asthma management. OBJECTIVE: To describe the real-world effectiveness of mepolizumab in patients with severe asthma stratified by common overlapping comorbidities. METHODS: This was a retrospective analysis of patients with asthma from the MarketScan Commercial and Medicare Supplemental Database initiating mepolizumab treatment (index date). Eligible patients had more than or equal to 1 claim (excluding claims for diagnostic tests) with a diagnosis code for more than or equal to 1 of 7 comorbidities (atopic disease, nasal polyps, chronic sinusitis, obesity, respiratory infections, chronic obstructive pulmonary disease, and depression/anxiety) during the 12-month preindex baseline period; these were used to stratify patients into 7 nonmutually exclusive subgroups. Outcomes included asthma exacerbations and exacerbation-related health care resource utilization during the 12-month baseline and follow-up periods. Each patient acted as their own control. RESULTS: Of the 639 patients included, the most common comorbidities were atopic diseases (73.2%), respiratory infections (55.6%), and chronic sinusitis (45.1%). Across all 7 comorbidity subgroups, there were significant (P < .05) reductions of 38% to 55% and 57% to 83% in exacerbations and exacerbations requiring hospitalization, respectively, during the follow-up vs baseline period, except for exacerbations requiring hospitalization in the nasal polyp subgroup, owing to the small subgroup sample size. During the follow-up vs baseline periods, mean number of oral corticosteroids claims was significantly (P < .001) reduced by 29% to 38%; 39% to 47% of patients achieved greater than or equal to 50% oral corticosteroids dose reduction. Significant reductions in exacerbation-related health care resource utilization were also observed. CONCLUSION: Mepolizumab treatment provided real-world clinical benefits in patients.

Background: In controlled clinical studies, mepolizumab has been shown to reduce exacerbation rates and the use of oral corticosteroids as well as improve asthma control and health-related quality of life compared with placebo in patients with severe eosinophilic asthma. However, real-world data on the impact of mepolizumab on clinical outcomes are limited. Objective: To evaluate the effect of mepolizumab on asthma exacerbations and asthma exacerbation-related costs in patients with severe asthma in U.S. clinical practice. Methods: This retrospective cohort study used U.S. administrative claims data from patients ages ≥12 years and with severe asthma at mepolizumab treatment initiation (index date; identification period, January 2015-June 2017) who had received two or more mepolizumab administrations within 180 days of the index date and had no evidence of treatment with another asthma biologic. The exacerbation rate and exacerbation-related costs were assessed in both the 12 months before mepolizumab initiation (baseline period) and the following 12 months (follow-up period). A clinical trial-like cohort was identified, defined as patients with two or more baseline exacerbations and ≥10 administrations during follow-up. Results: A total of 201 patients were included in the overall population and 74 patients in the clinical trial-like cohort. Mepolizumab significantly reduced the exacerbation rate between the baseline and follow-up periods in both the overall population and the clinical trial-like cohort (p < 0.001), which corresponded to 33.6% and 48.6% reductions, respectively. The rate of exacerbations in patients who required hospitalization between the baseline and follow-up periods was also reduced by 35.3% (p = 0.080) and 68.2% (p = 0.015) in the overall population and in the clinical trial-like cohort, respectively. Cost data were inconclusive. Conclusion: This study, which used real-world data, demonstrated that mepolizumab is associated with reductions in asthma exacerbations, in line with the findings from controlled clinical studies. These results provided further evidence of the effectiveness of mepolizumab in a real-world setting.

Purpose: Patients with chronic obstructive pulmonary disease (COPD) who are hospitalized are more likely to die from their illness and have increased likelihood of re-admission than those who are not. Subsequent re-admissions further increase the burden on healthcare systems. This study compared inpatient admission rates and time-to-first COPD-related inpatient admission among Medicare beneficiaries with COPD indexed on umeclidinium/vilanterol (UMEC/VI) versus tiotropium (TIO). Patients and Methods: This retrospective study used the All-Payer Claims Database to investigate hospital admission and re-admission outcomes in Medicare beneficiaries with COPD with an initial pharmacy claim for UMEC/VI or TIO from 1 January 2015 to 28 February 2020. Inpatient admissions, baseline, and follow-up variables were assessed in patients indexed on UMEC/VI and TIO after propensity score matching (PSM), with time-to-first on-treatment COPD-related inpatient admission as the primary endpoint. Re-admissions were assessed among patients with a COPD-related inpatient admission in the 30- and 90-days post-discharge. Results: Post-PSM, 7152 patients indexed on UMEC/VI and 7069 on TIO were eligible for admissions analysis. The mean (standard deviation [SD]) time-to-first COPD-related inpatient admission was 46.71 (87.99) days for patients indexed on UMEC/VI and 44.96 (85.90) days for those on TIO (p=0.06). The mean (SD) number of inpatient admissions per patient was 1.24 (2.92) for patients indexed on UMEC/VI and 1.26 (3.05) for those on TIO (p=0.49). Proportion of patients undergoing re-admissions was similar between treatments over both 30 and 90 days, excluding a significantly lower proportion of patients indexed on UMEC/VI than those indexed on TIO for COPD-related re-admissions for hospital stays of 4-7 days and 7-14 days, and all-cause re-admissions for stays of 4-7 days. Conclusion: Patients with COPD using Medicare in the US and receiving UMEC/VI or TIO reported similar time-to-first inpatient admission and similar proportion of re-admissions.

Purpose: Patients with chronic obstructive pulmonary disease (COPD) have been shown to benefit from triple therapy commonly delivered by multiple-inhaler triple therapy (MITT); however, the complexity of MITT regimens may decrease patient adherence. Fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI), a once-daily single-inhaler triple therapy (SITT), became available in the United States (US) in 2017, but real-world data comparing outcomes for SITT versus MITT are currently limited. This study compared outcomes among patients with COPD initiating MITT versus SITT with FF/UMEC/VI who were either Medicare Advantage with Part D (MAPD) beneficiaries or commercial enrollees in the US. Methods: Retrospective study using administrative claims data from the Optum Research Database for patients with COPD who initiated FF/UMEC/VI or MITT between September 1, 2017, and March 31, 2019 (index date: first pharmacy claim for FF/UMEC/VI cohort; earliest day of ≥30 consecutive days-long period of overlap in the day's supply of all triple therapy components for MITT cohort). COPD exacerbations, adherence to triple therapy, and all-cause and COPD-related health care resource utilization (HCRU) and costs were compared between FF/UMEC/VI and MITT initiators. Results: In total, 4659 FF/UMEC/VI initiators and 9845 MITT initiators for the MAPD population, and 821 FF/UMEC/VI initiators and 1893 MITT initiators for the commercial population were included in the study. MAPD beneficiaries initiating FF/UMEC/VI had a significantly lower annual rate of severe exacerbations compared to MITT initiators (0.26 vs 0.29; p=0.014). They also had a significantly higher mean adherence (proportion of days covered) (0.51 vs 0.37; p<0.001) and significantly lower all-cause and COPD-related inpatient stays compared to MITT initiators ([32.02% vs 34.27%; p=0.017], [16.09% vs 17.72%; p=0.037]). Trends were similar among the commercial population, but the results were not statistically significant. Conclusion: FF/UMEC/VI initiators had significantly fewer severe exacerbations, higher triple therapy adherence, and lower HCRU costs compared to MITT initiators for MAPD beneficiaries.

BACKGROUND: Herpes zoster (HZ) is a painful condition caused by reactivation of the varicella-zoster virus. The objectives of this study were to compare HZ incidence in adults with asthma versus adults without asthma and to compare healthcare resource use as well as direct costs in adults with HZ and asthma versus adults with asthma alone in the USA. METHODS: This retrospective longitudinal cohort study included adults aged ≥18 years across the USA. Patients were identified from Optum's deidentified Clinformatics Data Mart Database, an administrative claims database, between 1 October 2015 and 28 February 2020, including commercially insured and Medicare Advantage with part D beneficiaries. Cohorts of patients with and without asthma, and separate cohorts of patients with asthma and HZ and with asthma but not HZ, were identified using International Classification of Diseases 10th Revision, Clinical Modification codes. HZ incidence, healthcare resource use and costs were compared, adjusting for baseline characteristics, between the relevant cohorts using generalised linear models. RESULTS: HZ incidence was higher in patients with asthma (11.59 per 1000 person-years) than patients without asthma (7.16 per 1000 person-years). The adjusted incidence rate ratio (aIRR) for HZ in patients with asthma, compared with patients without asthma, was 1.34 (95% CI 1.32 to 1.37). Over 12 months of follow-up, patients with asthma and HZ had more inpatient stays (aIRR 1.11; 95% CI 1.02 to 1.21), emergency department visits (aIRR 1.26; 95% CI 1.18 to 1.34) and outpatient visits (aIRR 1.19; 95% CI 1.16 to 1.22), and direct healthcare costs that were US dollars ($) 3058 (95% CI $1671 to $4492) higher than patients with asthma without HZ. CONCLUSION: Patients with asthma had a higher incidence of HZ than those without asthma, and among patients with asthma HZ added to their healthcare resource use and costs.

BACKGROUND: Asthma is a common chronic respiratory disorder associated with significant disease and economic burden. Mepolizumab is an anti-IL-5 mAb approved for use as an add-on treatment in patients with severe eosinophilic asthma. OBJECTIVE: To assess the impact of mepolizumab initiation on asthma exacerbation frequency, oral corticosteroid (OCS) use, and asthma exacerbation-related costs in a US Medicare population. METHODS: This was a retrospective cohort study of mepolizumab claims from patients with asthma in the Centers for Medicare and Medicaid Services Medicare database carried out between January 2016 and December 2018. The index date (first claim for mepolizumab) was required to occur between January and December 2017. The baseline and follow-up periods were the 12 months before and 12 months after the index, respectively. Outcomes included changes in the proportion of patients experiencing exacerbations (primary), OCS use (secondary), and asthma exacerbation-related costs during the baseline and follow-up periods. RESULTS: The study identified 1,278 patients (mean age, 67.9 years; 65% female) with one or more prescription or administration claim for mepolizumab who were eligible for study inclusion. There was a significant relative reduction in the proportion of patients with an asthma exacerbation (27%; P < .0001) in the follow-up versus baseline period. Similarly, a lower proportion of patients received OCS for asthma (16% relative reduction; P < .0001), fewer patients were chronic OCS users (5 mg/day or more; 48% relative reduction; P < .0001), and there was a significant decrease in asthma exacerbation-related costs (total reduction, $888; P = .0002) during the follow-up versus the baseline period. CONCLUSION: Mepolizumab reduced exacerbations, OCS use, and exacerbation-related healthcare costs in a US Medicare population, confirming its benefits in this specific population with severe asthma.

Purpose: There is limited literature regarding real-world treatment patterns of patients with COPD, particularly since the introduction of once-daily single-inhaler triple therapy with fluticasone furoate/umeclidinium/vilanterol in 2017. Here, we evaluated treatment patterns of patients with COPD before and after a COPD exacerbation. Patients and Methods: Retrospective, descriptive study using medical and pharmacy claims data and enrollment information from the Optum® Clinformatics® Data Mart database. Patients aged ≥40 years with ≥1 COPD exacerbation on or after September 18, 2017 were included. The index date was the last day of the first COPD exacerbation (ie day of visit for a moderate exacerbation or discharge date for a severe exacerbation). The baseline period was 12 months prior to index and the follow-up period (≥3 months) spanned from index until the earliest of health plan disenrollment, end of data availability (September 30, 2020), or death. Treatment patterns were evaluated during baseline and follow-up, with a focus on medication switching in the 90 days pre- and post-index. Results: COPD exacerbations were identified in 307,727 patients (125,942 severe; 181,785 moderate). Mean age at index was 72.8 years; 56.3% were female. Before and after first exacerbation, 37.7% and 48.2% of patients used ≥1 controller medication, respectively. In the 90 days pre-index, ICS, LABA, and LAMA medications were used by 27.5% of patients. Of these users, 64.3% remained on the same medication class, 21.7% discontinued, and 14.1% switched medication in the 90 days post-index. Among switchers, 44.0% switched to triple therapy. Most common switches were ICS/LABA to ICS/LABA/LAMA (20.7%) and LAMA to ICS/LABA/LAMA (16.4%). Conclusion: Many COPD exacerbations occur among patients not on controller medications. Although the percentage of patients receiving a controller medication increased following a first exacerbation, it remained below 50%. Of patients receiving controller medications pre-exacerbation, only a small proportion escalated to triple therapy post-exacerbation.

Background: The COVID-19 pandemic has exponentially expanded the number of patients requiring treatment for chronic respiratory failure. One consequence is an increase in the number of patients requiring intubation and mechanical ventilation. Benign inoperable tracheal stenosis presents a challenge, especially in COVID-19 patients. Methods: We describe a case series of 15 patients with Benign inoperable tracheal stenosis treated with interventional bronchoscopy over a 15-month period. These patients were divided into two groups, COVID and non-COVID. We used an electrocautery snare as an electrocautery knife to cut the stenotic segment followed by four injections of 1 mg submucosal Decadron via a Wang needle. Patients were subsequently followed by the pulmonary clinic. Institutional review board approval was not required as per our institutional policy for a retrospective case series. Results: There was a high degree of success with this intervention, with a low rate of recurrence. We also noticed the following differences between the two subgroups. COVID tracheal stenosis was longer in length, had a higher percentage of cartilage involvement, and was located more distal to cords than the non-COVID group. The median age was younger in the COVID group. Conclusions: COVID pandemic an enormous number of intubations and tracheotomies have been performed. As a result, there will be an increased prevalence of tracheal stenosis. Most of these cases can be effectively treated with surgery. Dealing with complex inoperable cases remains a dilemma. Our case series/research article is an attempt to provide an easy technique with a high cure rate.
RESUMO
Purpose: Oral corticosteroids (OCS) play a role in the treatment of acute chronic obstructive pulmonary disease (COPD) exacerbations; however, chronic use is not recommended due to the high rate of systemic complications, development of comorbidities, and increased mortality. Data assessing the real-world impact of fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) on OCS utilization rates are limited. This study assessed the impact of FF/UMEC/VI on OCS use among patients with COPD previously treated with OCS. Patients and Methods: A retrospective database study of patients with COPD aged ≥40 years who initiated FF/UMEC/VI from 1 November 2017 to 31 December 2018, identified through the MarketScan® Commercial and Medicare Supplemental databases. Patients were required to have ≥1 dispensing of an OCS prior to initiation of FF/UMEC/VI (index) and were followed up for 12 months post-index. OCS utilization patterns, potential OCS-related adverse events, healthcare resource utilization (HCRU), and costs were compared between the 12-month pre- and post-index periods. Results: A total of 2013 patients were identified (mean age 63.5 years, 55.7% female). The proportion of patients with ≥1 OCS claim decreased by 32.2% between the pre- and post-index period (67.8% vs 100%; p < 0.001). Comparing the post-index period to the pre-index period, mean number of OCS pharmacy claims per patient decreased from 3.3 to 2.5 (p < 0.001) and mean daily dose was reduced from 3.1 to 2.6 mg/day (p = 0.004); 30.0% of patients reduced their daily dose by 90-100%. Reductions were also seen in COPD-related HCRU. The proportion of patients with an inpatient admission for COPD decreased from 11.4% to 7.1% (p < 0.001), emergency room visits decreased from 23.1% to 17.4% (p < 0.001), and office visits from 97.5% to 90.1% (p < 0.001). Similar results were seen for all-cause HCRU. Conclusion: Among patients with COPD with prior OCS use, FF/UMEC/VI initiation resulted in significant reductions in OCS utilization, COPD-related HCRU (including hospitalization), and all-cause HCRU.

Purpose: To examine the impact of initiating fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) in a single device on chronic obstructive pulmonary disease (COPD) exacerbations, COPD exacerbation-related costs, and all-cause and COPD-related healthcare resource utilization (HCRU) and costs in patients with COPD. Methods: Retrospective database analysis of patients with COPD aged ≥40 years who initiated FF/UMEC/VI between September 1, 2017, and December 31, 2018 (index date: first pharmacy claim for FF/UMEC/VI), following evidence of multiple-inhaler triple therapy (MITT) (≥30 consecutive days) in the year prior to index. COPD exacerbations, COPD exacerbation-related costs, and all-cause and COPD-related HCRU and costs were compared between the baseline period (12 months prior to and including index) and follow-up period (12 months following index). Results: Data from 912 patients (mean [SD] age: 71.2 [8.1], 51.2% female) were included in the analyses. Among the overall cohort, mean count of total COPD exacerbations (moderate or severe) per patient was statistically significantly lower in the follow-up period compared to baseline (1.2 vs 1.4, p=0.001). The proportion of patients with ≥1 COPD exacerbation (moderate or severe) was also statistically significantly lower in the follow-up period compared to baseline (56.4% vs 62.4%, p=0.001). All-cause and COPD-related HCRU were similar during follow-up compared to baseline, although the proportion of patients with COPD-related ambulatory visits was lower during follow-up (p<0.001). COPD-related office visit costs, emergency room visit costs, and pharmacy costs were statistically significantly lower during follow-up compared to baseline (p<0.001; p=0.019; p<0.001, respectively). Conclusion: In a real-world setting, patients on MITT who subsequently initiated FF/UMEC/VI in a single device had significant reductions in the rate of COPD exacerbations (moderate or severe). Switching to FF/UMEC/VI also resulted in improvements in some HCRU and cost outcomes. These data support the use of FF/UMEC/VI among patients at high risk of exacerbation to reduce future risk and improve outcomes.

Purpose: Real-world asthma control data among patients initiating fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) are limited. This study assessed rescue medication use and asthma-related exacerbations in patients with asthma before and after initiating single-inhaler FF/UMEC/VI using administrative claims data. Patients and Methods: This retrospective, pre-post cohort study analyzed data from the IQVIA PharMetrics Plus database (September 18, 2016âMarch 31, 2020). Patients aged ≥18 years that had ≥1 dispensing of single-inhaler FF/UMEC/VI 100/62.5/25 mcg (first dispensing = index date), ≥12 months of continuous health insurance enrollment prior to (pre-treatment) and following (post-treatment) FF/UMEC/VI initiation and ≥1 diagnosis of asthma during the pre-treatment period or on the index date were included. The primary endpoint was the number of oral corticosteroid (OCS) dispensings per patient per year during pre- and post-treatment periods. Secondary endpoints included asthma-related exacerbation rates and short-acting ß2-agonist (SABA) use. Comparisons between pre- and post-treatment periods were made using risk and rate ratios. Results: Overall, 890 patients with asthma initiating treatment with FF/UMEC/VI were included. The most recently dispensed controller medications prior to FF/UMEC/VI initiation were inhaled corticosteroids/long-acting ß2-agonists (33.5%) and leukotriene modifiers (33.0%). Patients had a 29% reduction in the number of OCS dispensings (rate ratio [95% confidence interval (CI)]: 0.71 [0.65, 0.77], P < 0.001) during post-treatment versus pre-treatment, with a 23% reduction in the proportion of patients with ≥1 OCS dispensing post-treatment (risk ratio [95% CI]: 0.77 [0.73, 0.82], P < 0.001). Significant reductions in rates (rate ratio [95% CI]) of asthma-related exacerbations (0.59 [0.52, 0.67], P < 0.001) and SABA use (0.80 [0.74, 0.86], P < 0.001) were also observed. Conclusion: In this real-world study, patients with asthma had significantly lower OCS use, asthma-related exacerbations, and SABA use following treatment initiation with FF/UMEC/VI compared with their pre-treatment period. These results suggest better asthma control following initiation of FF/UMEC/VI in a routine clinical practice setting.
RESUMO
Purpose: Inhaled triple therapy (TT) comprising a long-acting muscarinic antagonist, long-acting ß2 agonist, and inhaled corticosteroid is recommended for symptomatic chronic obstructive pulmonary disease (COPD) patients, or those at risk of exacerbation. However, it is not well understood which patient characteristics contribute most to future exacerbation risk. This study assessed patient predictors associated with future exacerbation time following initiation of TT. Patients and Methods: This retrospective cohort study used data from the Optum™ Clinformatics™ Data Mart, a large health claims database in the United States. COPD patients who initiated TT between January 2008 and March 2018 (index) were eligible. Patients were required to be aged ≥18 years at index and have continuous enrollment for the 12 months prior to index (baseline) and the 12 months following index (follow-up). Patients who had received TT during baseline were excluded. Data from eligible patients were analyzed using a reverse engineering forward simulation machine learning platform to predict future COPD exacerbation time. Results: Data from 73,625 patients were included. The model found that prior exacerbation was largely correlated with post-index exacerbation time; patients who had ≥4 exacerbation episodes during baseline had an average increase of 32.4 days post-index exacerbation, compared with patients with no exacerbations during baseline. Likewise, ≥2 inpatient visits (effect size 27.1 days), the use of xanthines (effect size 11.5 days), or rheumatoid arthritis (effect size 6.4 days) during baseline were associated with increased exacerbation time. Conversely, diagnosis of anemia (effect size -5.68 days), or oral corticosteroids in the past month (effect size -3.43 days) were associated with reduced exacerbation time. Conclusion: Frequent prior exacerbations, healthcare resource utilization, xanthine use, and rheumatoid arthritis were the strongest factors predicting the future increase of exacerbations. These results improve our understanding of exacerbation risk among COPD patients initiating triple therapy.

INTRODUCTION: Patients with chronic obstructive pulmonary disease (COPD) often have poor sleep quality and report a worsening of respiratory symptoms during night-time. However, current clinical guidelines for COPD management do not specifically consider nocturnal symptoms when recommending pharmacological treatment. This study aimed to better understand the burden of nocturnal symptoms in patients with COPD, and to evaluate the importance of nocturnal symptom control compared with daytime and overall symptom control. METHODS: Data were analyzed from the Adelphi Respiratory Disease Specific Programme, a point-in-time survey of physicians and their patients, conducted in the USA in 2019. Primary care physicians and pulmonologists who managed three or more patients with COPD per month were eligible for inclusion; eligible patients were ≥ 18 years old, with a physician-confirmed diagnosis of COPD. RESULTS: Surveys from 171 physicians and 800 patients were analyzed. Everyday symptoms were reported in 14% of patients. In total, 88% of patients reported daytime symptoms, and 74% of patients experienced nocturnal symptoms, with 7% reporting daily nocturnal symptoms. Patients experiencing nocturnal symptoms every day had the greatest impairment in their activity as per the Work Productivity and Activity Impairment questionnaire (mean total activity impairment, 66.9%; nocturnal symptoms once or twice a week, 41.1%; no nocturnal symptoms, 26.4%). Patients experiencing daily nocturnal symptoms also had the lowest quality of life (QoL) as per the EuroQoL 5-Dimension 3-Level score. Physicians reported prescribing therapy based on sustained 24-h symptomatic relief for the majority of patients (78%). They reported nocturnal symptom control as a factor in their choice of therapy for 38% of patients, and daytime symptom control as a reason for 61% of patients. CONCLUSION: Daytime and nocturnal symptoms are common among patients with COPD. Frequency of nocturnal symptoms is related to a significant impairment in activity and health-related QoL.
RESUMO
INTRODUCTION: Single-inhaler fluticasone furoate/umeclidinium/vilanterol (FF/UMEC/VI) triple therapy was approved by the United States Food and Drug Administration in 2017 as a maintenance therapy for chronic obstructive pulmonary disease (COPD). Patient characteristics and treatment patterns prior to initiating FF/UMEC/VI are currently unknown. This study assessed patient characteristics, exacerbation, and medication history in patients with COPD before the initiation of FF/UMEC/VI or multiple-inhaler triple therapy (MITT). METHODS: This was a retrospective study using the Optum Clinformatics® Data Mart. Patients who initiated FF/UMEC/VI triple therapy or MITT (consisting of a long-acting muscarinic antagonist [LAMA], long-acting ß2-agonist [LABA], and inhaled corticosteroid [ICS]) between October 2017 and September 2018, were enrolled in commercial or Medicare Advantage Prescription Drug plans, were aged > 40 years, and had a COPD diagnosis were eligible. Patient characteristics, comorbidities, COPD medication use, exacerbations, and eosinophil counts were assessed in the 12-month baseline period prior to initiation of FF/UMEC/VI triple therapy or MITT. RESULTS: The study population included 3933 FF/UMEC/VI users and 18,244 MITT users. Mean (standard deviation) patient age was 72.2 (8.6) years in FF/UMEC/VI users and 70.7 (9.7) years in MITT users. Prior to initiating triple therapy, the majority of FF/UMEC/VI (89.1%) and MITT (93.8%) users experienced a moderate or severe exacerbation or used a COPD maintenance therapy during the baseline period. In addition, 41.2% of FF/UMEC/VI users received overlapping ICS/LAMA/LABA, 20.3% received ICS/LABA, and 9.7% received LAMA/LABA. CONCLUSION: In this population of COPD patients, triple therapy was frequently initiated after previous maintenance medication use or an exacerbation, in line with treatment guideline recommendations.
RESUMO
Purpose: There is a high prevalence of chronic obstructive pulmonary disease (COPD) in the United States (US). Although guidelines are available for the treatment of COPD, evidence suggests that management of COPD in clinical practice is not always aligned with this guidance. This study aimed to further understand the current use of COPD maintenance medication in the US. Patients and Methods: This study was an analysis of data from the Adelphi Respiratory Disease Specific Programme (DSP™) 2019. Point-in-time data were collected from participating US physicians and their COPD patients. Physicians were either primary care physicians (PCPs) or pulmonologists, with a minimum workload of ≥3 COPD patients per month. Patients were aged ≥18 years with a physician-confirmed diagnosis of COPD. Results: In total, 171 physicians completed the survey (92 PCPs and 79 pulmonologists). Mean patient age was 66.4 years, 45% were female, with moderate COPD in 49.4% of patients and severe/very severe in 19.3%. Pulmonologists more frequently prescribed dual bronchodilation and triple therapy than PCPs, whereas inhaled corticosteroid/long-acting ß2-agonist was more frequently prescribed by PCPs than pulmonologists. For both physician types, the most common reason for prescribing their patients' current treatment was 24-hour symptom relief. The majority of PCPs (70.1%) and pulmonologists (71.9%) reported referring to COPD guidelines when making treatment decisions. Conclusion: Prescribing patterns for COPD patients were found to differ between PCPs and pulmonologists. Improved physician understanding of how to tailor treatment for each patient, based on current symptoms and exacerbation risk, could help optimize patient care in COPD.

BACKGROUND: Addition of a long-acting muscarinic antagonist is recommended for patients with asthma uncontrolled on inhaled corticosteroid/long-acting ß2-agonist therapy. This is the first large-scale, real-world study examining multiple-inhaler triple-therapy (MITT) use in asthma. OBJECTIVE: To describe real-world prevalence, outcomes, and treatment patterns associated with MITT. METHODS: This retrospective cohort study used medical and pharmacy claims from the Optum Research Database. Patients were diagnosed with asthma between January 01, 2013, and July 31, 2018, with evidence of MITT use (≥1 overlapping days' supply of inhaled corticosteroid, long-acting ß2-agonist, and long-acting muscarinic antagonist). Annual MITT prevalence (primary end point) was assessed in the prevalent population; eligible patients were 18 years or older with 2 or more asthma diagnoses during the study period, and continuous enrollment for the entire year. Secondary outcomes (adherence [proportion of days covered], MITT persistence, health care resource utilization, costs) were assessed in the incident MITT population; eligible patients were 18 years or older, with 2 or more asthma diagnoses and continuous enrollment during both the 12-month baseline and 12-month follow-up periods. Patients with chronic obstructive pulmonary disease or cystic fibrosis were excluded. RESULTS: MITT prevalence was low but increased from 0.35% (95% CI, 0.32-0.37) in 2014/2015 to 1.00% (95% CI, 0.96-1.04) in 2017/2018. Among 1831 incident MITT users, there was a substantial disease burden, demonstrated by high health care resource utilization and exacerbation rates. Adherence and persistence to MITT was low (mean proportion of days covered, 0.31 ± 0.27), and 12% (n = 216) remained on MITT 12 months postinitiation. CONCLUSIONS: Overall, MITT use among patients with asthma is low. Patients initiating MITT have substantial disease burden and significant unmet needs.
