Economic burden in patients with anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC), with or without brain metastases, receiving first-line ALK inhibitors.

INTRODUCTION: This observational study describes the real-world economic burden in patients with anaplastic lymphoma kinase (ALK) positive non-small cell lung cancer (NSCLC) receiving a first-line ALK inhibitor, and the economic impact of brain metastases (BM). METHODS: Administrative claims data (Truven Health MarketScan® Commercial Claims and Encounters database and Medicare Supplemental and Coordination of Benefits database; January 1, 2015-March 31, 2020) for adult patients with ALK+ NSCLC who received a first-line ALK inhibitor were retrospectively reviewed. Healthcare costs and resource utilization were calculated on a per-patient-per-month (PPPM) basis and stratified by the presence or absence of BM prior to first-line ALK inhibitor. Factors associated with costs were identified. RESULTS: A total of 496 patients were eligible for analysis. Mean PPPM total healthcare costs were $21,961 for all patients receiving up to 1 year of a first-line ALK inhibitor. Patients were significantly more likely to have higher mean PPPM total costs if they had BM prior to first-line ALK inhibitor (vs. no BM; odds ratio: 1.11; 95% confidence interval: 1.02, 1.21; p = 0.013). Mean PPPM days of hospital stay (p = 0.0056), and inpatient hospital visits (p = 0.0030) were significantly higher for patients with BM compared to no BM. The main cost drivers for non-inpatient procedures for all patients were medications, radiation therapy, and other diagnostic procedures. CONCLUSIONS: The economic burden in patients with ALK+ NSCLC receiving a first-line ALK inhibitor was high. Patients with ALK+ NSCLC and BM had higher healthcare costs and resource utilization than patients without BM.

[Comparison of Disease Burden Factors of Thyroid Cancer Between China and the World From 1990 to 2019].

Objective To compare the prevalence and disease burden of thyroid cancer and their trends between China and the globe from 1990 to 2019.Methods With the global disease burden data in 2019,Joinpoint was used to predict the trends of the disease burden of thyroid cancer in China and the globe from 1990 to 2019,and logarithmic linear model was used to test the predicted trends.The R language was used for predictive analysis and graphic plotting of the disease burden from 2020 to 2035.Results From 1990 to 2019,the standardized incidence rate and the standardized mortality rate of thyroid cancer in China were lower than those in the globe.The standardized incidence rate in China and the globe showed an increasing trend(with the increases of 102.65% and 40.65%,respectively),while the standardized mortality rate showed a decreasing trend(with the decreases of 7.63% and 4.91%,respectively).Compared with those of the female population,the standardized incidence and mortality rates of the Chinese male population increased significantly from 1990 to 2019(the rates of change in the male population were 48.65% and 214.60%,respectively;and the rates of change in the female population were -39.01% and 60.44%,respectively).China's overall standardized years of life lost(YLL),years lived with disability(YLD),and disability-adjusted life years(DALY)rates during the 30-year period were lower than the global average.The Chinese and global populations showed the standardized YLL rate decreasing by 16.61% and 6.88% and the standardized DALY rate decreasing by 10.77% and 3.65%,respectively,while the rates of standardized YLD increased by 128.91% and 46.89%,respectively.The magnitude of DALY in China and the world was mainly influenced by YLL.The standardized incidence,mortality,and DALY rates of the Chinese male population were gradually approaching the global levels.From 1990 and 2019,thyroid cancer showed a higher mortality rate in the population with the age ≥ 75 years and a higher incidence rate in the population with the age <75 years.It is projected that from 2020 to 2035,the standardized incidence rates in China and the world will increase by 36.66% and 21.15%,respectively;the standardized mortality rates will decrease by 20.19% and 3.46%,respectively;and the standardized DALY rate is expected to decrease by 7.08% in China and increase by 4.35% in the world.Conclusions From 1990 to 2019,China's standardized incidence rate of thyroid cancer increased and had a higher increase than the global level,and the standardized mortality rate decreased,with a slightly higher decrease than the global level.However,the increases in the standardized incidence rate and mortality rate of this disease in China's ≥75 years male population were severe.Although China's disease burden of thyroid cancer showed a decreasing trend in line with the global trend as a whole,the disease burden in the Chinese males was higher than that in the females.Specifically,the disease burden due to premature death was predominant,and the burden in specific populations requires policy attention.

Analysis of cognitive ability and adaptive behavior assessment tools used in an observational study of patients with mucopolysaccharidosis II.

BACKGROUND: Mucopolysaccharidosis II (MPS II) is a rare lysosomal storage disease characterized by cognitive impairment in most patients. This post hoc analysis evaluated changes in cognitive function, adaptive behavior and functional outcomes in patients with neuronopathic MPS II over time. Fifty-five children with MPS II were enrolled in a 24-month observational study (NCT01822184). The Differential Ability Scales, second edition (DAS-II; early years battery for ages 2 years 6 months to 6 years 11 months, school age battery for ages 7 years to 17 years 11 months), Vineland Adaptive Behavior Scales, second edition (VABS-II) and the Hunter Syndrome-Functional Outcomes for Clinical Understanding Scale (HS-FOCUS) were performed at baseline and 3-month intervals over 2 years. A subgroup of 38 children with a DAS-II General Conceptual Ability (GCA) score of 55-85 (below average-very low abilities) at any time during the study were included in this analysis. RESULTS: Mean (standard deviation [SD]) early years DAS-II GCA score decreased from 73.4 (15.7, n = 22) at baseline to 62.7 (34.9, n = 6) at month 24. For the six patients with early years GCA assessments at baseline and month 24, mean (SD) GCA scores decreased from 72.3 (21.3) at baseline to 62.7 (34.9) at month 24. School age GCA scores were stable over 2 years: mean (SD) 72.4 (11.8, n = 10) at baseline; 74.3 (12.3, n = 8) at month 24. Mean (SD) VABS-II Adaptive Behavior Composite (ABC) scores were stable throughout the study (baseline, 81.8 [11.8, n = 36]; month 24, 81.0 [10.2, n = 13]). Some associations between items and domains of HS-FOCUS (p < 0.05) and DAS-II GCA and VABS-II ABC scores were shown, but there was no clear pattern of changes in HS-FOCUS over 2 years. CONCLUSIONS: The DAS-II measured changes in cognitive function over 2 years in younger patients with MPS II, whereas cognitive function in older patients remained stable. Further research is required to confirm the content validity of the DAS-II in different patient populations with MPS II. The VABS-II and HS-FOCUS were not sensitive tools for measuring behavioral and functional changes over 2 years. These findings may inform selection of appropriate cognitive and behavioral assessment tools for future studies.

Economic Burden Associated with Major Surgery in Patients with von Willebrand Disease: A United States Retrospective Administrative Database Analysis.

PURPOSE: To estimate the incremental economic burden of major surgeries in patients with von Willebrand disease (VWD). PATIENTS AND METHODS: This was a retrospective analysis of the IBM Health MarketScan® database (2008-2018). Patients with at least two healthcare visits for VWD in the database who had undergone at least one major surgery unrelated to VWD (identified via International Classification of Diseases, Ninth and Tenth Revisions procedure codes) were included. Patients without VWD with major surgeries were selected from a 1% random database sample. All patients had ≥12 months of continuous healthcare plan enrollment before and following their first major surgery. Patients with VWD were matched (1:1) with patients without VWD using propensity score matching. Regression models compared healthcare resource utilization and costs between the matched cohorts over a 12-month period after patients' index major surgery. RESULTS: After propensity score matching, 2972 pairs were selected. Musculoskeletal and digestive surgeries were the two most common major surgeries (patients with VWD, 39.6% and 25.0%; without VWD, 37.1% and 23.4%, respectively). Patients with VWD were significantly more likely (p<0.0001) to have an inpatient admission (odds ratio = 1.71; 95% confidence interval [CI] 1.52-1.92) or emergency room visit (odds ratio = 1.41; 95% CI 1.25-1.59) than patients without VWD. The numbers of inpatient admissions (incidence rate ratio [IRR] = 1.47; 95% CI 1.35-1.60), emergency room visits (IRR = 1.44; 95% CI 1.31-1.59), and outpatient visits (IRR = 1.16; 95% CI 1.11-1.21) per patient were also significantly greater for patients with VWD than for those without VWD (p<0.0001). Patients with VWD incurred significantly higher (p<0.0001) total healthcare costs (medical and pharmacy) per patient than patients without VWD ($50,733.89 versus $30,154.84, respectively). CONCLUSION: Healthcare resource utilization and associated costs among patients undergoing major surgeries were significantly higher for those with VWD than for patients without VWD.

Economic burden of major bleeding events in commercially insured patients with von Willebrand disease based on claims data from the United States.

BACKGROUND: von Willebrand disease (VWD) can lead to serious, life-threatening bleeding events associated with substantial clinical and economic burden. OBJECTIVE: To estimate the prevalence, health care resource utilization (HCRU), and costs associated with major bleeding events in patients with VWD. METHODS: This was a retrospective analysis of the IBM MarketScan database (2008-2016). Selected patients had ≥ 2 VWD diagnoses, no diagnosis of acquired coagulation factor deficiency, and continuous health care plan enrollment for ≥ 12 months from eligibility start date. Prevalence was calculated as the proportion of eligible patients with ≥ 1 major bleeding event during the observation period (start to end of continuous eligibility). HCRU and costs in the 12-month continuous enrollment period following the first major bleeding event were compared with those from a comparable 12-month period for patients without major bleeding events. RESULTS: Of the 19,785 patients with VWD, 15% experienced ≥ 1 major bleeding event during a median follow-up of 4 years; 89% of these events were gastrointestinal bleeds. For the economic analysis, 773 patients with ≥ 1 major bleeding event and 4,285 patients without major bleeding events met the selection criteria. Controlling for baseline covariates, patients with major bleeding events had significantly (P < 0.0001) more inpatient admissions (incidence rate ratio [IRR] = 3.2; 95% CI = 2.78-3.77), longer inpatient stays (IRR = 3.9; 95% CI = 3.12-4.93), and more emergency department visits (IRR = 2.0; 95% CI = 1.77-2.27) and outpatient visits (IRR = 1.3; 95% CI = 1.19-1.34) than patients without major bleeding events. Annual health care costs were significantly higher (P < 0.01) for patients with major bleeding events than those without them (predicted mean cost differences: total = $20,890, pharmacy = $2,593, and medical = $18,293). CONCLUSIONS: Major bleeding events were associated with increased HCRU and costs, mostly inpatient costs. Therefore, optimizing therapy to prevent or reduce major bleeding events has the potential to reduce health care use and costs in patients with VWD.

Economic burden in patients with ALK + non-small cell lung cancer, with or without brain metastases, receiving second-line anaplastic lymphoma kinase (ALK) inhibitors.

Aims: To describe the real-world economic burden of patients with anaplastic lymphoma kinase-positive (ALK+) non-small cell lung cancer (NSCLC) treated with post-crizotinib, second-line ALK inhibitor therapy.Materials and methods: Retrospective analysis using data from US Optum: Clinformatics Data Mart administrative claims database. Adult patients with ALK + NSCLC treated with ceritinib or alectinib as second-line ALK inhibitors between 1 January 2011 and 30 September 2017 were included. Healthcare costs and resource utilization for up to 1 year of therapy were calculated on a per-patient-per-month (PPPM) basis and stratified by presence or absence of brain metastases (BM). Multivariate regression analysis was performed to identify factors associated with costs. Top ten cost drivers of non-inpatient procedure costs were recorded.Results: One hundred and twelve patients received second-line ALK inhibitors. Total mean PPPM healthcare costs were $23,984 for all patients receiving up to 1 year of post-crizotinib, second-line ALK inhibitor therapy. Total mean PPPM costs for patients with BM on or prior to post-crizotinib, second-line ALK inhibitor therapy were 1.37-times as high as those for patients without BM (p = 0.0406). Mean PPPM outpatient visits and inpatient hospitalization stays were higher for patients with BM versus no BM. The main cost drivers for non-inpatient procedures were radiation therapy, medications, and diagnostic radiology.Limitations: Analyses did not include newer ALK-directed therapies. BM development after the index date (defined as the date of the first claim for a second-line ALK inhibitor) may have been misclassified as non-BM. Findings may not be generalizable to patients with no health insurance coverage.Conclusions: Treatment of patients with ALK + NSCLC with ceritinib or alectinib as post-crizotinib, second-line ALK inhibitor therapy represents a high economic burden. Healthcare costs and resource utilization were significantly higher for patients with ALK + NSCLC with BM versus no BM.

The Option Value of Innovative Treatments for Metastatic Melanoma.

Background Treatment options in oncology have increased in recent years due to the quick pace of innovation. In the cancer care landscape, therapies that enable patients to live to the next innovation have additional value, "option value," from the benefit of surviving to the next innovation. In such disease areas, providers and payers should consider this value when gauging the value of new therapies. The purpose of this study is to develop a model to estimate the additional survival patients attain from a therapy that allows them to live to benefit from further advances in care, and to apply the model to immunotherapy for metastatic melanoma. Methods The benefit of a therapy extends beyond immediate tumor control; it can also allow patients to live to benefit from further advances in care. This is a therapy's option value. Using data from the SEER cancer registry and clinical trial publications, we developed a model to estimate option value and applied it to ipilimumab, the first immune checkpoint modulator used to treat metastatic melanoma. Because ipilimumab extends survival, select patients benefited from survival extension to live to benefit from the introduction of PD-1 inhibitors (i.e. pembrolizumab and nivolumab). We calculated the option value of ipilimumab in terms of additional life-months patients gained by living to become potential candidates for PD-1 inhibitors, discounting at 3% per year. Results Patients taking ipilimumab as a second-line therapy for metastatic melanoma gained 10.5 months compared to patients taking the prior standard of care. Patients diagnosed in 2011, 2012, and 2013 gained an additional 1.6, 2.8, and 5.1 months of life expectancy, respectively, by living to see the introduction of PD-1 inhibitors. This equates to an option value of 15%, 27%, and 49%, respectively, of the conventionally calculated survival gain from ipilimumab. Ipilimumab had greater option value for patients diagnosed in later years who were more likely to live to the introduction of PD-1 inhibitors. Conclusions Therapies that enable patients to see further advances in care have option value. Option value is particularly important to patients with disease areas undergoing rapid innovation.

The option value of innovative treatments for non-small cell lung cancer and renal cell carcinoma.

OBJECTIVES: To develop a model of the option value a therapy provides by enabling patients to live to see subsequent innovations and to apply the model to the case of nivolumab in renal cell carcinoma (RCC) and non-small cell lung cancer (NSCLC). STUDY DESIGN: A model of the option value of nivolumab in RCC and NSCLC was developed and estimated. METHODS: Data from the Surveillance, Epidemiology, and End Results (SEER) cancer registry and published clinical trial results were used to estimate survival curves for metastatic cancer patients with RCC, squamous NSCLC, or nonsquamous NSCLC. To estimate the conventional value of nivolumab, survival with the pre-nivolumab standard of care was compared with survival with nivolumab assuming no future innovation. To estimate the option value of nivolumab, long-term survival trends in RCC and squamous and nonsquamous NSCLC were measured in SEER to forecast mortality improvements that nivolumab patients may live to see. RESULTS: Compared with the previous standard of care, nivolumab extended life expectancy by 6.3 months in RCC, 7.5 months in squamous NSCLC, and 4.5 months in nonsquamous NSCLC, according to conventional methods. Accounting for expected future mortality trends, nivolumab patients are likely to gain an additional 1.2 months in RCC, 0.4 months in squamous NSCLC, and 0.5 months in nonsquamous NSCLC. These option values correspond to 18%, 5%, and 10% of the conventional value of nivolumab, respectively. CONCLUSIONS: Option value is important when valuing therapies like nivolumab that extend life in a rapidly evolving area of care.

Association Between Breast Cancer Disease Progression and Workplace Productivity in the United States.

OBJECTIVE: Determine workplace productivity losses attributable to breast cancer progression. METHODS: Longitudinal analysis linking 2005 to 2012 medical and pharmacy claims and workplace absence data in the US patients were commercially insured women aged 18 to 64 diagnosed with breast cancer. Productivity was measured as employment status and total quarterly workplace hours missed, and valued using average US wages. RESULTS: Six thousand four hundred and nine women were included. Breast cancer progression was associated with a lower probability of employment (hazard ratio [HR] = 0.65, P < 0.01) and increased workplace hours missed. The annual value of missed work was $24,166 for non-metastatic and $30,666 for metastatic patients. Thus, progression to metastatic disease is associated with an additional $6500 in lost work time (P < 0.05), or 14% of average US wages. CONCLUSIONS: Breast cancer progression leads to diminished likelihood of employment, increased workplace hours missed, and increased cost burden.

The social value of childhood vaccination in the United States.

OBJECTIVES: To determine the lifetime social value of using the guideline-recommended vaccines for children born in the United States in 2009. STUDY DESIGN: This study utilized an economic model with parameter values sourced from clinical and observational data, as well as the literature. METHODS: The model quantified the health effects of routine vaccination for 14 diseases in terms of quality-adjusted life-years (QALYs) saved. The health effects were then valued by applying an economic value of a QALY. Producers' profits were estimated using data on vaccine prices, profit margins, and the number of vaccines administrated in the 2009 US birth cohort. The costs of producing the vaccines were subtracted from the value of the health effects to yield the total social value of vaccination. The producers' and consumers' shares of this social value were calculated. Sensitivity analyses were conducted to determine how results depend on underlying parameter assumptions. RESULTS: Estimates indicated that vaccination of this cohort will save 1.2 million QALYs, relative to no vaccination. Of those health gains, 88% stemmed from reduced mortality and 12% from reduced morbidity. We estimated a social value of $184.1 billion from these gains, of which $3.4 billion accrues to manufacturers as profits, while $180.7 billion accrues to the rest of society. In sensitivity analysis, the total social value ranged from $40 billion to $675 billion, and the manufacturers' share ranged from 0.3% to 11.5%. CONCLUSIONS: Policy makers should account for this social value when considering policies affecting incentives to vaccinate and develop new vaccines.
