Cardiovascular comorbidities in a United States patient population with hemophilia A: A comprehensive chart review
PURPOSE: Previous retrospective claims database analyses reported increased prevalence and earlier onset of cardiovascular comorbidities in patients with versus without hemophilia A. A comprehensive chart review was designed to further investigate previous findings.
METHODS: This retrospective chart review study was conducted at Henry Ford Health System (Detroit, MI, USA). Baseline demographics, bleeding events, treatment parameters, coexisting diseases, hemophilia-associated events, Charlson Comorbidity Index score, and prevalence of 12 cardiovascular risk factors and associated diseases were compared between hemophilia A and control cohorts. P values from a chi-square test for categorical variables and a t test for continuous variables were calculated. Because of small sample sizes (N = 0-90, most \u3c50), statistical differences between cohorts were also assessed using absolute standardized difference.
RESULTS: Both groups were well matched by age, race, healthcare payer, and study year. The Charlson Comorbidity Index score was similar between groups. Prevalence of bleeds, hepatitis B and C, and HIV/AIDS was higher in the hemophilia cohort. Hemophilia A severity was severe, moderate, mild, or unknown in 52.7%, 10.8%, 10.8%, and 25.7% of patients, respectively. Prevalence of 12 cardiovascular risk factors and diseases was numerically higher in the control cohort, but differences were statistically significant (P ≤ 0.05) only for diabetes and hyperlipidemia. Meaningful statistical differences using standardized differences were not reached for venous and arterial thrombosis and atrial fibrillation.
CONCLUSIONS: This retrospective chart review did not confirm statistically significant differences in cardiovascular comorbidities and their earlier onset in hemophilia A versus controls. Results suggest numerically higher comorbidities in controls

Abstract PS9-54: Healthcare costs for metastatic breast cancer patients treated with human epidermal growth factor receptor 2 targeted agents
Abstract Background: Human Epidermal Growth Factor Receptor 2 positive (HER2+) breast cancer (BC) represents approximately 15% of early stage BC cases and is associated with a more aggressive clinical phenotype and poor prognosis with respect to most BC. Over the last decade new HER2-targeted therapies have become available that have prolonged survival for both early stage and metastatic breast cancer (mBC). However, the cost impact of these therapies has not been fully assessed in recent years. Given the evidence for major clinical benefit, it is imperative that health systems evaluate new treatments to maximize the value of health care expenditures. This study evaluated healthcare costs among mBC patients treated with HER2-targeted therapy. Methods: A retrospective cohort study using the IQVIA Real-World Data Adjudicated Claims Database (1/1/2015-7/31/2019) was conducted. Adult (≥18-years) female patients who initiated HER2-targeted therapy with evidence of mBC diagnosis in the prior year were identified. The study index date was the initiation date of the HER2-targeted agent after which, patients were required to have ≥12 months of follow-up. Annual all-cause and BC-related healthcare costs per patient (2019 USD) were computed using payer-paid amounts in the first and second year following the index date. BC-related costs were defined as costs for claims with a primary diagnosis for BC (ICD-9-CM: 174.% or ICD-10-CM: C50.%) or BC-related treatment (surgery – mastectomy or lumpectomy, HER2-targeted therapy, chemotherapy, hormone therapy, immunotherapy, and radiation). Results: 708 mBC patients treated with HER2-targeted therapy were included with a mean age (SD) of 53.2 (10.2) years and mean follow-up of about 2 years. During the follow-up period, trastuzumab (96.5%) and pertuzumab (81.2%) were the most common HER2-targeted therapies used followed by ado-trastuzumab (15.4%), neratinib (6.3%), and lapatinib (5.3%). Additionally, patients received other treatments including chemotherapy (88.0%), hormone therapy (56.6%), and radiation therapy (57.6%). Of note, 40.3% of patients underwent surgery (mastectomy or lumpectomy) following evidence of metastasis. Following initiation of HER2-targeted therapy, mean annual costs per patient in Year 1 and Year 2 were 196,139, respectively. Correspondingly, BC-related costs in Year 1 and Year 2 were 144,978, respectively. HER2-targeted therapies accounted for 72% of BC-related costs in both Year 1 and 2. Surgery patients incurred 70,885 higher BC-related costs, mainly due to a differences in BC treatment rates in Year 2 for HER2 targeted drugs, other BC drugs and radiation. Conclusion: Total BC-related costs of mBC patients treated with HER2-targeted therapy is highest in the first year following treatment initiation, with the main cost driver being the cost of HER2-targeted therapy. While total costs decreased in the subsequent year, the cost of HER2 targeted therapy remained the dominant component. Results of this study highlight the significant economic burden of treating HER2+ mBC and also the need for therapies that limit disease progression.

Health Care Resource Utilization and Costs for Metastatic Breast Cancer Patients Newly Treated with Human Epidermal Growth Factor Receptor 2 (HER2)-Targeted Agents
HER2-positive metastatic breast cancer (mBC) is an incurable disease associated with years of chronic therapy and excess cost. HER2-targeted therapies have shown survival benefit for early-stage and mBC; however, the economic impact of these therapies has not been fully assessed. We evaluated health care resource use (HCRU) and costs of mBC patients treated with HER2-targeted therapy.
This was a retrospective cohort study using the IQVIA Real-World Data Adjudicated Claims Database (July 1, 2014 to July 31, 2019). Female patients aged ≥18 years with mBC who initiated HER2-targeted therapy in the prior year were identified. The index date was the initiation date of the HER2-targeted agent, after which patients were required to have ≥12 months of follow-up. Annual and cumulative all-cause and BC-related costs (2019 USD) and annual BC-related HCRU were computed in years 1, 2, and 3 following the index date.
Following the initiation of HER2-targeted therapy, the mean annual total all-cause costs per patient in years 1 (n = 423), 2 (n = 357), and 3 (n = 166) were 224,343), 185,287), and 197,901), respectively. The mean annual total BC-related costs were 151,230), 148,058), and 159,374) in years 1, 2, and 3, respectively. A major portion of BC-related costs were costs associated with HER2-targeted treatment. The 3-year cumulative all-cause and BC-related total costs were 456,920) and 401,319), respectively.
Treatment of HER2-positive mBC is a substantial economic burden. A potential approach to minimizing cost and HCRU is to prevent recurrence

Use and cost comparison of clobazam to other antiepileptic drugs for treatment of Lennox-Gastaut syndrome.
Background: Lennox-Gastaut syndrome (LGS) is a severe form of childhood-onset epilepsy associated with serious injuries due to frequent and severe seizures. Of the antiepileptic drugs (AEDs) approved for LGS, clobazam is a more recent market entrant, having been approved in October 2011. Recent AED budget impact and cost-effectiveness analyses for LGS suggest that adding clobazam to a health plan formulary may result in decreased medical costs; however, research on clinical and economic outcomes and treatment patterns with these AED treatments in LGS is limited. Objectives: To compare the baseline characteristics and treatment patterns of new initiators of clobazam and other AEDs among LGS patients and compare healthcare utilization and costs before and after clobazam initiation among LGS patients. Methods: A retrospective study of probable LGS patients was conducted using the MarketScan® Commercial, Medicare Supplemental, and Medicaid databases (10/1/2010-3/31/2014). Results: In the Commercial/Medicare Supplemental population, clobazam users were younger, had fewer comorbidities, and more prior AED use than non-clobazam users. In the 12 months pre-treatment initiation, clobazam users had significantly more seizure-related inpatient stays and outpatient visits and higher total seizure-related (P < 0.001) and all-cause (P < 0.001) costs than non-clobazam users. Among clobazam users, when compared to the 12 months pre-clobazam initiation, seizure-related medical utilization and costs were lower in the 12 months post-clobazam initiation (P = 0.004). Total all-cause (P < 0.001) and seizure-related (P = 0.029) costs increased post-clobazam initiation mainly due to the increase in outpatient pharmacy costs. Similar results were observed in the Medicaid population. Conclusions: Baseline results suggest a prescribing preference for clobazam in severe LGS patients. Clobazam users had a reduction in seizure-related medical utilization and costs after clobazam initiation. The improvement in medical costs mostly offset the higher prescription costs following clobazam initiation
