RESUMO
BACKGROUND: Nasal polyps (NPs) are commonly associated with chronic rhinosinusitis (CRS). In keeping with the unified airway hypothesis, asthma and CRS with NP (CRSwNP) frequently co-occur, share a similar pathophysiology, and are often treated with oral corticosteroids (OCS); however, a need for alternative treatment options for patients with comorbid asthma and CRSwNP remains. OBJECTIVE: To characterize the short- and long-term dual airway effectiveness of the anti-interleukin-5 monoclonal antibody, mepolizumab, in real-world patients with asthma and comorbid NP. METHODS: Adult patients with CRSwNP who initiated mepolizumab from November 1, 2014, to September 30, 2021, were identified from 2 Merative MarketScan Research Databases. Outcomes were compared for the 12 months pre- and post-mepolizumab initiation and a variable follow-up period. Primary outcomes included the following: annual rate and proportion of patients with NP- and asthma-related exacerbations; NP surgery occurrences; all-cause OCS claims, number of OCS bursts, and daily OCS dose; all-cause and NP-related health care resource utilization. RESULTS: During the 12 months post-index, patients experienced fewer NP- and asthma-related exacerbations, required fewer sinus surgeries, and reduced use of OCS, with fewer all-cause OCS claims and OCS bursts. Significant reductions in asthma exacerbation-related and NP-related health care resource utilization were also observed. CONCLUSION: This study illustrated the near- and long-term real-world effectiveness of mepolizumab treatment, with a focus on dual lower and upper airway benefit from single-agent add-on therapy. These results may aid physicians in clinical decision-making for patients with asthma and comorbid CRSwNP with complex care needs.
RESUMO
INTRODUCTION: Fremanezumab, a humanized monoclonal antibody targeting calcitonin gene-related peptide, is indicated for preventive treatment of migraine in adults. Real-world evidence assessing the effect of fremanezumab on migraine-related medication use, health care resource utilization (HCRU), and costs in patient populations with comorbidities, acute medication overuse (AMO), and/or unsatisfactory prior migraine preventive response (UPMPR) is needed. METHODS: Data for this US, retrospective claims analysis were obtained from the Merative® MarketScan® Commercial and supplemental databases. Eligible adults with migraine initiated fremanezumab between 1 September 2018 and 30 June 2019 (date of earliest fremanezumab claim is the index date), had ≥ 12 months of continuous enrollment prior to initiation (preindex period) and ≥ 6 months of data following initiation (postindex period; variable follow-up after 6 months), and had certain preindex migraine comorbidities (depression, anxiety, and cardiovascular disease), potential AMO, or UPMPR. Changes in migraine-related concomitant acute and preventive medication use, HCRU, and costs were assessed pre- versus postindex. RESULTS: In total, 3193 patients met the eligibility criteria. From pre- to postindex, mean (SD) per patient per month (PPPM) number of migraine-related acute medication and preventive medication claims (excluding fremanezumab), respectively, decreased from 0.97 (0.90) to 0.86 (0.87) (P < 0.001) and 0.94 (0.74) to 0.81 (0.75) (P < 0.001). Migraine-related outpatient and neurologist office visits, emergency department visits, and other outpatient services PPPM decreased pre- versus postindex (P < 0.001 for all), resulting in a reduction in mean (SD) total health care costs PPPM from US$541 (US$858) to US$490 (US$974) (P = 0.003). Patients showed high adherence and persistence rates, with mean (SD) proportion of days covered of 0.71 (0.29), medication possession ratio of 0.74 (0.31), and persistence duration of 160.3 (33.2) days 6 months postindex. CONCLUSIONS: Patients with certain migraine comorbidities, potential AMO, and/or UPMPR in a real-world setting had reduced migraine-related medication use, HCRU, and costs following initiation of fremanezumab.

RESUMO
OBJECTIVE: We describe the impact of acute myeloid leukemia (AML) diagnosis on workplace absenteeism and disability days among patients and their caregivers. METHODS: This retrospective study included adults with newly diagnosed AML (2009-2019) and adult caregivers of patients with newly diagnosed AML, identified from the US Merative™ MarketScan® Commercial Database. The Merative MarketScan Health and Productivity Management Database provided linked patient-level records of workplace absence and short-term (STD) and long-term disability (LTD) data. Endpoints included workplace absence, STD and LTD for patients and caregivers during 12 months pre-AML (baseline) and ≤3 years' follow-up, and corresponding cost of work loss. RESULTS: Patient workplace absence decreased in the months post-AML diagnosis, but the number of STD and LTD leave days claimed increased significantly by sixfold and fourfold, respectively. The proportion of patients making STD leave claims increased within 4-5 months of diagnosis, while the proportion making LTD leave claims increased significantly starting from month 5. Caregiver workplace absence peaked in the first 2 months post-diagnosis and remained elevated versus baseline throughout the study. CONCLUSION: AML diagnosis leads to workplace absenteeism and increased economic burden for patients with AML and their caregivers.

BACKGROUND: Several biologics are now approved in the US as add-on treatments for chronic rhinosinusitus with nasal polyps (CRSwNP). This cross-sectional, retrospective, real-world study aimed to characterize treatment patterns and identify predictors of biologic use among patients with CRSwNP. METHODS: Adults in the Merative MarketScan Commercial and Medicare Supplemental Databases with medical claims for CRSwNP were identified June 2018-June 2019 (identification period [IP]). Patient characteristics were collated in the IP and treatment pattern data during the IP plus the following year (July 2019-June 2020; observation period [OP]). Data were stratified by sinus surgery and biologic use. RESULTS: Of the 5997 eligible patients identified (58% male, mean age 48.1 years), 10.7% (n = 642) used biologics during the OP. More biologic users had common respiratory conditions than non-users, particularly asthma (89.1% vs 35.0%; P < 0.001). Biologic users had fewer diagnostic services but more drug-related services than non-users. Only 11.6% of patients who had sinus surgery used biologics, with most (56.1%) having their first biologic dose before sinus surgery and 12.5% ≤ 30 days after. Oral corticosteroid (OCS) use was higher in biologic users than non-users (all patients: 68.8% vs 42.5%; P < 0.001) and in those with/without sinus surgery. Comorbidities, prior OCS/doxycycline use, and age (< 65 years) increased the odds of biologic use, with asthma increasing the odds 5.46 times (P < 0.001). CONCLUSIONS: Biologic use was more common before first/next sinus surgery and in patients with high unmet need, elucidating predictors of biologic use that could be used in clinical practice.
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.

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.

Palivizumab has been shown to decrease RSV-related hospitalization (RSVH) risk and reduce RSVH severity. American Academy of Pediatrics (AAP) guidance on administration of palivizumab has changed over time; in 2014, palivizumab was no longer recommended in preterm infants born at 29 weeks gestational age (wGA) or later. This study's objective was to describe RSVH risk and severity in preterm infants (29-34 wGA) without comorbidities relative to healthy term infants and to each other by gestational age. Using the MarketScan Multi-State Medicaid and Commercial Databases, infants born from July 1, 2014 to June 30, 2019, at 29-34 wGA (preterm) and >37 wGA (term) were identified. During RSV seasons (November to March) from 2014 to 2020, claims incurred by infants while they were <6 months old were evaluated for RSVH and RSVH characteristics. This study included 63,351 preterm infants and 1,076,389 term infants without outpatient palivizumab administration. Rate of RSVH was higher in infants with lower wGA at birth and ranged 3.32-5.72 per 100 infant-seasons in Medicaid-insured infants and 3.21-4.84 in commercially insured infants. Relative risk of RSVH was 5-8 times higher in Medicaid-insured preterm infants and 3-5 times higher in commercially insured preterm infants compared to term infants. ICU admissions and mechanical ventilation were more common during RSVH in preterm infants relative to term infants. RSV-related outpatient healthcare utilization was also 2-3 times higher in preterm infants born at 31-34 wGA. Increased utilization of palivizumab among infants born at 29-34 wGA may decrease RSVH rates and result in less severe course in preterm infants with RSVH.

BACKGROUND: Osteoarthritis (OA) is a leading cause of chronic pain and disability. Prior studies have documented racial disparities in the clinical management of OA. The objective of this study was to assess the racial variations in the economic burden of osteoarthritis within the Medicaid population. METHODS: We conducted a retrospective observational study using the MarketScan Multi-State Medicaid database (2012-2019). Newly diagnosed, adult, knee and/or hip OA patients were identified and followed for 24 months. Demographic and clinical characteristics were collected at baseline; outcomes, including OA treatments and healthcare resource use (HCRU) and expenditures, were assessed during the 24-month follow-up. We compared baseline patient characteristics, use of OA treatments, and HCRU and costs in OA patients by race (White vs. Black; White vs. Other) and evaluated racial differences in healthcare costs while controlling for underlying differences. The multivariable models controlled for age, sex, population density, health plan type, presence of non-knee/hip OA, cardiovascular disease, low back pain, musculoskeletal pain, presence of moderate to severe OA, and any pre-diagnosis costs. RESULTS: The cohort was 56.7% White, 39.9% Black and 3.4% of Other race (American Indian/Alaska Native, Hispanic, Asian, Native Hawaiian/Other Pacific Islander, two or more races and other). Most patients (93.8%) had pharmacologic treatment for OA. Inpatient admission during the 24-month follow-up period was lowest among Black patients (25.8%, p < .001 White vs. Black). In multivariable-adjusted models, mean all-cause expenditures were significantly higher in Black patients ($25,974) compared to White patients ($22,913, p < .001). There were no significant differences between White patients and patients of Other race ($22,352). CONCLUSIONS: The higher expenditures among Black patients were despite a lower rate of inpatient admission in Black patients and comparable length and number of hospitalizations in Black and White patients, suggesting that other unmeasured factors may be driving the increased costs among Black OA patients.
Higher healthcare costs were observed in Black Medicaid patients with knee/hip osteoarthritis despite lower rates of inpatient admission. We observed these differences in this Medicaid population, where socioeconomic status is more homogeneous.Black patients had significantly higher healthcare costs compared to White patients and the difference persisted even after accounting for underlying differences in Black and White patients.Higher healthcare costs among Black patients were found in both the baseline and follow-up periods overall for all types of healthcare (hospitalizations, ER, office visit, other services).Higher hospitalization costs in Black patients were observed despite lower rates of hospitalizations in Black patients. These increased costs cannot be attributed to either longer or more frequent hospitalizations; no significant difference in either the length of stay or the number of hospitalizations was observed when comparing Black patients to White patients.

In the United States (US), meningococcal serogroup B (MenB) vaccination has been recommended for 16-23-year-olds (preferably 16-18 years) based on shared clinical decision-making since 2015. MenB vaccine coverage (≥1 dose) by age 17 years has been reported, but initiation at older ages and by insurance type is unknown. In this retrospective cohort study, MarketScan claims data were analyzed to assess MenB vaccine series initiation (i.e. receipt of a first dose) during 2017-2020 among US commercially insured and Medicaid-covered individuals aged 16-18 and 19-23 years. Kaplan-Meier curves were generated to estimate series initiation at various times from index (latest of 1/1/2017 or 16th/19th birthday, depending on the cohort). Multivariable analyses were conducted to identify factors associated with series initiation. Among 1,450,354 Commercial and 1,140,977 Medicaid 16-18-year-olds, MenB vaccine series initiation rates within 3 years of each person's first eligibility were estimated to be 33% and 20%, respectively; among 1,857,628 Commercial and 747,483 Medicaid 19-23-year-olds, 3% and 1%, respectively. Factors identified to be significantly associated with increased likelihood of initiating a MenB vaccine series included co-administration of meningococcal serogroups ACWY (MenACWY) vaccine, younger age, female sex, nonwhite race (Medicaid only), New England or Middle Atlantic location (Commercial only), urban residence, and previous influenza vaccination. MenB vaccine series initiation among the studied US adolescents and young adults was low. There is a need for continued efforts to better understand barriers to the uptake of vaccines that are recommended based on shared clinical decision-making.

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.

Respiratory syncytial virus (RSV) is a leading cause of bronchiolitis and pneumonia in children under one year and a leading cause of infant hospitalization. Palivizumab was approved by the FDA in 1998 as RSV immunoprophylaxis to prevent severe RSV disease in children with specific health conditions and those born at <35 weeks gestational age (wGA). This study compared RSV-related hospitalization (RSVH) and RSVH characteristics in very preterm (<29 wGA) and term (>37 wGA) infants. Using the MarketScan Commercial and Multi-State Medicaid administrative claims databases, infants born between 7/1/2003 and 6/30/2020 were identified and classified as very preterm or term. Infants with evidence of health conditions, such as congenital heart disease and cystic fibrosis, were excluded. During 2003-2020 RSV seasons (November to March), claims incurred by infants while they were <12 months old were evaluated for outpatient administration of palivizumab and RSVH. The study included 40,123 very preterm infants and 4,421,942 term infants. Rate of RSVH in very preterm infants ranged 1.5-3.8 per 100 infant-seasons in commercially insured infants and 3.5-8.4 in Medicaid insured infants and were inversely related to wGA at birth. Relative risk of RSVH in very preterm was 3-4 times higher, and ICU admissions and mechanical ventilation were more common during RSVH in very preterm infants relative to term infants. However, these outcomes were less common or less severe in very preterm infants who received outpatient palivizumab administration, despite evidence of higher baseline risk of RSVH in these infants.

BACKGROUND: In the United States, meningococcal serogroup B (MenB) vaccination is recommended for 16-23-year-olds based on shared clinical decision-making. We estimated series completion among individuals initiating MenB vaccination for the 2 available vaccines: MenB 4-component (MenB-4C, doses at 0 and ≥1 month) and MenB factor H binding protein (MenB-FHbp, doses at 0 and 6 months). METHODS: This retrospective health insurance claims data analysis included 16-23-year-olds who initiated MenB vaccination (index date) during January 2017 to November 2018 (MarketScan Commercial Claims and Encounters Database) or January 2017 to September 2018 (MarketScan Multi-State Medicaid Database) and had continuous enrollment for ≥6 months before and ≥15 months after index. The main outcome was MenB vaccine series completion within 15 months. Among noncompleters, preventive care/well-child and vaccine administrative office visits were identified as potential missed opportunities for series completion. Robust Poisson regression models identified independent predictors of series completion. RESULTS: In the Commercial (n = 156,080) and Medicaid (n = 57,082) populations, series completion was 56.7% and 44.7%, respectively, and was higher among those who initiated MenB-4C versus MenB-FHbp (61.1% versus 49.8% and 47.8% versus 33.9%, respectively; both P < 0.001). Among noncompleters, 40.2% and 34.7% of the Commercial and Medicaid populations, respectively, had ≥1 missed opportunity for series completion. Receipt of MenB-4C and younger age were independently associated with a higher probability of series completion. CONCLUSIONS: Series completion rates were suboptimal but were higher among those who initiated MenB-4C. To maximize the benefits of MenB vaccination, interventions to improve completion and reduce missed opportunities should be implemented.

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.

PURPOSE: Patients with life-threatening asthma typically experience recurrent exacerbations, are dependent on oral corticosteroids (OCSs), and have considerable asthma-related health care costs. Data on the impact of mepolizumab on exacerbations and OCS use in patients with life-threatening asthma in real-world clinical practice are limited. This study assessed the impact of mepolizumab on exacerbation rates and OCS use in patients with life-threatening asthma in a real-word setting. METHODS: This retrospective study utilized data from US administrative claims from patients with life-threatening asthma. Eligible patients were treated between November 1, 2015, and December 31, 2017; were ≥12 years of age upon mepolizumab initiation (index date); and had undergone at least two mepolizumab administrations during the 6 months postindex. Data from the 12 months before (baseline) and after (follow-up) index were collected, with each patient serving as his or her own control. Life-threatening asthma was defined as at least three exacerbations and/or at least one asthma-related hospitalization during baseline, and/or a history of endotracheal intubation. Asthma exacerbation frequency and OCS use were assessed. FINDINGS: The analysis included 327 patients who received a mean (SD) of 10.6 (4.3) mepolizumab doses during follow-up. The percentage of patients experiencing at least one exacerbation and the mean exacerbation rate were significantly reduced from baseline to follow-up with mepolizumab, from 94.5% to 67.9% (P < 0.001), and from 3.2 to 1.5 events per patient per year, corresponding to a 53.1% relative reduction (P < 0.001). The percentage of patients with OCS claims was reduced by 12.6%, from 99.1% to 86.5% (P < 0.001). Of the patients who had a reduction in mean daily OCS use, most (57.9%, 140/242) had a reduction in mean daily OCS use of at least 50%. IMPLICATIONS: These data from patients with life-threatening asthma in clinical practice demonstrated that asthma exacerbation and OCS use were significantly reduced with mepolizumab treatment.

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: Patients with severe asthma often require oral corticosteroid (OCS) treatment. Clinical trials have demonstrated that mepolizumab can reduce OCS dependence, but real-world data are limited. OBJECTIVE: To evaluate the impact of mepolizumab on OCS use, asthma exacerbations, and asthma exacerbation-related costs in a real-world setting. METHODS: This retrospective cohort study (GSK ID: 209642; HO-19-19597) analyzed data from the MarketScan® Commercial database (identification period: November 2015-September 2017). Patients were ≥12 years old at mepolizumab initiation (index date), had a baseline asthma diagnosis, and received ≥2 mepolizumab administrations in the first 6 months of follow-up. OCS use, asthma exacerbation rate, and asthma exacerbation-related costs were assessed in the 12-months before (baseline) and 12-months after (follow-up) mepolizumab initiation. RESULTS: Mepolizumab was associated with a 14.7% reduction in the proportion of patients with ≥1 OCS claim from baseline to follow-up (93.4% vs 79.7%; P<0.001). The mean numbers of OCS claims/patient and OCS bursts (≥20 mg prednisone equivalents for 3â28 days) between baseline and follow-up were also reduced by 29.1% (P<0.001) and 36.8% (P<0.001), respectively. Reductions in chronic OCS use were demonstrated during follow-up in patients with baseline mean OCS dose ≥5mg and those with a mean OCS dose ≥10mg 90 days before index; the proportion of patients with no OCS use also increased from 6.6% to 20.3% between baseline and follow-up. CONCLUSION: Our findings demonstrate that mepolizumab therapy is associated with reduced OCS use in patients treated in a real-world setting, potentially mitigating adverse health sequelae caused by OCS use in these patients.
RESUMO
RATIONALE: Results from clinical trials in patients with severe eosinophilic asthma have demonstrated that mepolizumab is well tolerated and is associated with improved asthma control as evidenced by reductions in both exacerbations and maintenance oral corticosteroid use, and improvements in lung function, asthma control, and quality of life. However, real-world data are lacking on the impact of mepolizumab treatment. OBJECTIVE: To assess the effect of mepolizumab treatment on the rate of asthma exacerbations and asthma exacerbation-related costs in a real-world setting. METHODS: This retrospective cohort study (GSK ID: 209017; HO-18-19168) analyzed data from patients with severe asthma ≥12 years of age at mepolizumab treatment initiation (index date) with ≥12 months pre- (baseline) and post-index (follow-up) data from a commercial claims database (patients were identified from November 1, 2015 to March 31, 2017). Asthma exacerbations (primary objective) and asthma exacerbation-related costs (secondary objective) in the baseline and follow-up periods were compared. Other analyses included the number of mepolizumab administrations and the use of concomitant asthma medications. RESULTS: Data were analyzed from 346 patients. Mepolizumab significantly reduced the proportion of patients with any exacerbation and exacerbations requiring hospitalization, compared with baseline. Significant reductions in the rate of all exacerbations of 38.4% (from 2.68 to 1.65 events/patient/year; P<0.001) and of exacerbations requiring hospitalization of 72.7% (from 0.11 to 0.03 events/patient/year; P=0.004) were observed, compared with baseline. Mean total asthma exacerbation-related costs (excluding mepolizumab acquisition and administrative costs) per person were significantly lower during follow-up compared with baseline (P<0.05) and the use of asthma medications, including oral and inhaled corticosteroids, was also lower. CONCLUSION: This study confirms the clinical benefit observed in previous mepolizumab clinical trials and demonstrates that mepolizumab is effective in a real-world setting.
RESUMO
Objective: To assess healthcare resource utilization (HRU) and costs in children of mothers with and without postpartum depression (PPD).Methods: Administrative claims data from the IBM Watson Health MarketScan Databases (2010-2016) were used. Women with live births (index date = delivery date) were identified and linked to their newborns. The mother-child pairs were divided into PPD and non-PPD exposure cohorts based on claims for depression, mood or adjustment disorders, or anxiety identified in the mother between 15 and 365 days after delivery. Mother-child pairs with PPD exposure were propensity score matched 1:3 to mother-child pairs without PPD exposure. Children were required to have 24 months of continuous health plan enrolment following delivery. Additional comparisons were performed between mother-child pairs with and without preterm delivery.Results: Overall, 33,314 mother-child pairs with PPD exposure were propensity score matched to 102,364 mother-child pairs without PPD exposure. During the 24-month follow-up period, HRU across most service categories was significantly higher among children in the PPD exposure cohort than non-PPD exposure cohort. Among outpatient services, the percentages of children with a physician specialist service (68% versus 64%), early-intervention screening (40% versus 37%), and an emergency room visit (48% versus 42%) were greater in children of mothers with PPD (all p < .001). Furthermore, children of mothers with PPD incurred 12% higher total healthcare costs in the first 24 months of life compared to children of mothers without PPD ($24,572 versus $21,946; p < .001). After excluding mothers with preterm delivery, the proportion of children with ER visits, physician specialist services, and outpatient pharmacy claims was significantly higher in the PPD exposure cohort than non-PPD exposure cohort (all p < .001).Conclusion: The results of this analysis suggest that HRU and costs over the first 24 months of life in children of mothers with PPD exceeded that of children of mothers without evidence of PPD.

OBJECTIVE: Hospital admission is a key cost driver among patients with skin and soft tissue infections (SSTI). Data suggest that many SSTI patients are hospitalized unnecessarily and can be managed effectively and safely in an outpatient setting at a substantially lower cost. Oritavancin (ORI) is a single-dose treatment that has the potential to shift care from the inpatient to the outpatient setting. This study sought to compare the 30-day hospital admission rates and mean healthcare costs among SSTI patients who received outpatient ORI or vancomycin (VAN). METHOD: Over a 1-year period, outpatient prescription claims for VAN and ORI among patients with SSTIs and no hospitalization in past 3 days were for VAN and ORI were analyzed using a retrospective cohort analysis of the Truven Health MarketScan Databases. RESULTS: During the study period, 120 and 6695 patients who received ORI and VAN, respectively, met inclusion criteria. Groups were well matched at baseline. After covariate adjustment, patients who received ORI had a significantly lower 30- day admission rate versus patients who received VAN (6.1% vs 16.2%, respectively; P = .003). Mean healthcare costs 30-day post index were comparable between ORI and VAN patients ($12 695 vs $12 717, respectively; P = 1.0). CONCLUSIONS: Results suggest that ORI provides a single-dose alternative to multidose VAN for treatment of SSTI in the outpatient setting and may result in lower 30-day hospital admission rates.
RESUMO
BACKGROUND: Two MenB vaccines with different dosing schedules are approved in the US: MenB-4C (2 doses) and MenB-FHbp (2-3 doses). Both vaccines were licensed on the basis of immunogenicity demonstrated after vaccine series completion. We evaluated vaccination completion and adherence to dosing schedules. METHODS: This retrospective analysis used data from MarketScan Commercial Claims and Encounters Database (Commercial) January 1, 2015 - February 28, 2018 and Multi-State Medicaid Database (Medicaid) January 1, 2015 - December 31, 2017 to examine vaccine series completion and adherence to dosing schedule in individuals who initiated a MenB series at ages 16-23â¯years. Vaccine series completion and dose schedule adherence were assessed during a 15-month follow-up period after the first dose. Completion was defined as individual receipt of the recommended number of doses, with current recommendations applied retroactively to allow individuals who initiated the MenB-FHbp series to be complete with either the 2- or the 3-dose schedule. RESULTS: The study population comprised 65,205 commercially-insured individuals (36,118 initiated MenB-4C; 29,087 initiated MenB-FHbp) and 13,535 Medicaid-covered individuals (10,153 initiated MenB-4C; 3382 initiated MenB-FHbp). In Commercial, 63% of individuals who initiated MenB-4C and 52% of individuals who initiated MenB-FHbp completed vaccination within 15â¯months; dosing schedule adherence was 62% for MenB-4C initiators and 18% for MenB-FHbp initiators. In Medicaid, 15-month completion rates for MenB-4C and MenB-FHbp initiators were 49% and 31%, respectively, with corresponding dosing schedule adherence of 48% and 8%. Among individuals who completed the series, median time to completion was 68â¯days for MenB-4C versus 258â¯days for MenB-FHbp in Commercial and 88â¯days for MenB-4C versus 309â¯days for MenB-FHbp in Medicaid. CONCLUSION: During the study period, MenB vaccine series completion was suboptimal. However, completion was significantly higher for MenB-4C, with notably shorter time to completion. This may reflect the flexible dosing schedule of MenB-4C.
