Objective:

To describe dosing patterns and to compare the drug costs per month spent in progression-free survival (PFS) among patients with advanced renal cell carcinoma (aRCC) treated with everolimus or axitinib following a first tyrosine kinase inhibitor (TKI).

Methods:

A medical record retrospective review was conducted among medical oncologists and hematologists/oncologists in the US. Patient eligibility criteria included: (1) age ≥18 years; (2) discontinuation of first TKI (sunitinib, sorafenib, or pazopanib) for medical reasons; (3) initiation of axitinib or everolimus as a second targeted therapy during February 2012–January 2013. Real-world dosing patterns were summarized. Dose-specific drug costs (as of October 2014) were based on wholesale acquisition costs from RED BOOK Online. PFS was compared between everolimus and axitinib using a multivariable Cox proportion hazards model. Everolimus and axitinib drug costs per month of PFS were compared using multivariable gamma regression models.

Results:

A total of 325 patients received everolimus and 127 patients received axitinib as second targeted therapy. Higher proportions of patients treated with axitinib vs everolimus started on a higher than label-recommended starting dose (14% vs 2%) or experienced dose escalation (11% vs 1%) on second targeted therapy. The PFS did not differ significantly between patients receiving everolimus or axitinib (adjusted hazard ratio (HR)?=?1.16; 95% confidence interval [CI]?=?0.73–1.82). After baseline characteristics adjustment, axitinib was associated with 17% ($1830) higher drug costs per month of PFS compared to everolimus ($12,467 vs $10,637; p?<?0.001).

Limitations:

Retrospective observational study design and only drug acquisition costs considered in drug costs estimates.

Conclusions:

Patients with aRCC receiving axitinib as second targeted therapy were more likely to initiate at a higher than label-recommended dose and were more likely to dose escalate than patients receiving everolimus. With similar observed durations of PFS, drug costs were significantly higher—by 17% per month of PFS—with axitinib than with everolimus.  相似文献

Abstract

Objective:

Everolimus and axitinib are approved in the US to treat patients with advanced renal cell carcinoma (RCC) after failure on sunitinib or sorafenib, and one prior systemic therapy (e.g., sunitinib), respectively. Two indirect comparisons performed to evaluate progression-free survival in patients treated with everolimus vs axitinib suggested similar efficacy between the two treatments. Therefore, this analysis compares the lifetime costs of these two therapies among sunitinib-refractory advanced RCC patients from a US payer perspective.

Research design and methods:

A Markov model was developed to simulate a cohort of sunitinib-refractory advanced RCC patients and estimate the cost of treating patients with everolimus vs axitinib. The following health states were included: stable disease without adverse events (AEs), stable disease with AEs, disease progression (PD), and death. The model included the following resources: active treatments, post-progression treatments, adverse events, physician and nurse visits, scans and tests, and palliative care. Resource utilization inputs were derived from a US claims database analysis. Additionally, a 3% annual discount rate was applied to costs, and the robustness of the model results was tested by conducting sensitivity analyses, including those on dosing scheme and post-progression treatment costs.

Results:

Base case results demonstrated that patients treated with everolimus cost an average of $12,985 (11%) less over their lifetimes than patients treated with axitinib. The primary difference in costs was related to active treatment, which was largely driven by axitinib’s higher dose intensity. Results remained consistent across sensitivity analyses for AE and PD treatment costs, as well as dose intensity and discount rates.

Conclusion:

The results suggest that everolimus likely leads to lower lifetime costs than axitinib for sunitinib-refractory advanced RCC patients in the US.  相似文献

Abstract

Objective:

To estimate the costs of adverse events (AEs) in patients aged ≥65 years with metastatic renal cell carcinoma (mRCC).

Methods:

Retrospective study using the linked Surveillance, Epidemiology and End Results (SEER) Medicare database. Study subjects consisted of persons in SEER-Medicare, aged ≥65 years, with evidence of newly diagnosed mRCC between January 1, 2007 and December 31, 2007. Adverse events of interest consisted of Grade 3 or 4 toxicities that have been reported with frequency ≥5% in randomized controlled trials of sunitinib, sorafenib, bevacizumab, and pazopanib (i.e., targeted therapies for mRCC), and included abdominal pain, back pain, diarrhea, dyspnea, extremity pain, fatigue/asthenia, hand-foot syndrome, hypertension, lymphopenia, nausea/vomiting, neutropenia, proteinuria, and thrombocytopenia. Patients in SEER-Medicare with these events were identified based on ICD-9-CM diagnosis codes on Medicare claims. For each AE of interest, costs were tallied among evented patients over 30 days, beginning with the date of each patient’s first mention of the AE, and were compared with those of non-evented patients over a similar 30-day period beginning with an identical ‘shadow’ index date. Total costs were compared on an unadjusted basis and with adjustment for differences in baseline characteristics using a generalized linear model.

Results:

A total of 881 patients with mRCC met study entry criteria; 60% of these patients had Medicare claims with mention of one or more AEs of interest. Events occurring with frequency >20% included abdominal pain, dyspnea, and fatigue/asthenia; 10–20% of study subjects had encounters for back pain, extremity pain, and nausea/vomiting. Mean (standard deviation) total cost of care over 30 days was substantially higher among patients with AEs ($13,944 [$14,529]) compared with those without mention of these events ($1878 [$5264]). Adjusting for differences in baseline characteristics, the mean (95% confidence interval) difference in costs between evented and non-evented patients was $12,410 ($9217–$16,522). Study limitations include problems in event ascertainment due to inaccuracies in ICD-9-CM coding on Medicare claims data, and restriction of the study population to patients with metastatic involvement at initial diagnosis of RCC.

Conclusions:

Costs of care are substantially higher in patients aged ≥65 years with mRCC who experience AEs commonly associated with sunitinib, sorafenib, bevacizumab, and pazopanib. Efforts to prevent and/or better manage these events potentially can reduce healthcare costs.  相似文献

Objective:

To analyze medical costs and healthcare resource utilization (HRU) associated with everolimus-based therapy or chemotherapy among post-menopausal women with hormone-receptor-positive, human-epidermal-growth-factor-receptor-2-negative (HR+/HER2?) metastatic breast cancer (mBC).

Methods:

Patients with HR+/HER2? mBC who discontinued a non-steroidal aromatase inhibitor and began a new line of treatment with everolimus-based therapy or chemotherapy (index therapy/index date) between July 20, 2012 and April 30, 2014 were identified from two large claims databases. All-cause, BC-related, and adverse event (AE)-related medical costs (in 2014 USD) and all-cause HRU per patient per month (PPPM) were analyzed for both treatment groups across patients’ first four lines of therapies for mBC. Adjusted differences in costs and HRU between the everolimus and chemotherapy treatment group were estimated pooling all lines and using multivariable generalized linear models, accounting for difference in patient characteristics.

Results:

A total of 3298 patients were included: 902 everolimus-treated patients and 2636 chemotherapy-treated patients. Compared to chemotherapy, everolimus was associated with significantly lower all-cause (adjusted mean difference?=?$3455, p?<?0.01) and BC-related ($2510, p?<?0.01) total medical costs, with inpatient ($1344, p?<?0.01) and outpatient costs ($1048, p?<?0.01) as the main drivers for cost differences. Everolimus was also associated with significantly lower AE-related medical costs ($1730, p?<?0.01), as well as significantly lower HRU (emergency room incidence rate ratio [IRR]?=?0.83; inpatient IRR?=?0.74; inpatient days IRR?=?0.65; outpatient IRR?=?0.71; BC-related outpatient IRR?=?0.57; all p?<?0.01).

Conclusions:

This retrospective claims database analysis of commercially-insured patients with HR+/HER2? mBC in the US showed that everolimus was associated with substantial all-cause, BC-related, and AE-related medical cost savings and less utilization of healthcare resources relative to chemotherapy.  相似文献

Aims: Guidelines on treating invasive candidiasis recommend initial treatment with a broad-spectrum echinocandin (e.g. micafungin), then switching to fluconazole if isolates prove sensitive (de-escalation strategy). This study aimed to evaluate the cost-effectiveness of de-escalation from micafungin vs escalation from fluconazole from a Chinese public payers perspective.

Materials and methods: Cost-effectiveness was estimated using a decision analytic model, in which patients begin treatment with fluconazole 400?mg/day (escalation) or micafungin 100?mg/day (de-escalation). From Day 3, when susceptibility results are available, patients are treated with either fluconazole (if isolates are fluconazole-sensitive/dose-dependent) or micafungin (if isolates are resistant). The total duration of (appropriate) treatment is 14 days. Model inputs are early (Day 3) and end-of-treatment mortality rates, treatment success rates, and health resource utilization. Model outputs are costs of health resource utilization over 42 days, incremental cost per life-year, and incremental cost per quality-adjusted life-year (QALY) over a lifetime horizon.

Results: In the base-case analysis, the de-escalation strategy was associated with longer survival and higher treatment success rates compared with escalation, at a lower overall cost (–¥1,154; –175 United States Dollars). Life-years and QALYs were also better with de-escalation. Thus, this strategy dominated the escalation strategy for all outcomes. In a probabilistic sensitivity analysis, 99% of 10,000 simulations were below the very cost-effective threshold (1?×?gross domestic product).

Limitations: The main limitation of the study was the lack of real-world input data for clinical outcomes on treatment with micafungin in China; data from other countries were included in the model.

Conclusion: A de-escalation strategy is cost-saving from the Chinese public health payer perspective compared with escalation. It improves outcomes and reduces costs to the health system by reducing hospitalization, due to an increase in the proportion of patients receiving appropriate treatment.  相似文献

Aims: This study assessed the cost-effectiveness of ezetimibe with statin therapy vs statin monotherapy from a US payer perspective, assuming the impending patent expiration of ezetimibe.

Methods: A Markov-like economic model consisting of 28 distinct health states was used. Model population data were obtained from US linked claims and electronic medical records, with inclusion criteria based on diagnostic guidelines. Inputs came from recent clinical trials, meta-analyses, and cost-effectiveness analyses. The base-case scenario was used to evaluate the cost-effectiveness of adding ezetimibe 10?mg to statin in patients aged 35–74 years with a history of coronary heart disease (CHD) and/or stroke, and with low-density lipoprotein cholesterol (LDL-C) levels ≥70?mg/dL over a lifetime horizon, assuming a 90% price reduction of ezetimibe after 1 year to take into account the impending patent expiration in the second quarter of 2017. Sub-group analyses included patients with LDL-C levels ≥100?mg/dL and patients with diabetes with LDL-C levels ≥70?mg/dL.

Results: The lifetime discounted incremental cost-effectiveness ratio (ICER) for ezetimibe added to statin was $9,149 per quality-adjusted life year (QALY) for the base-case scenario. For patients with LDL-C levels ≥100?mg/dL, the ICER was $839/QALY; for those with diabetes and LDL-C levels ≥70?mg/dL, it was $560/QALY. One-way sensitivity analyses showed that the model was sensitive to changes in cost of ezetimibe, rate reduction of non-fatal CHD, and utility weight for non-fatal CHD in the base-case and sub-group analyses.

Limitations: Indirect costs or treatment discontinuation estimation were not included.

Conclusions: Compared with statin monotherapy, ezetimibe with statin therapy was cost-effective for secondary prevention of CHD and stroke and for primary prevention of these conditions in patients whose LDL-C levels are ≥100?mg/dL and in patients with diabetes, taking into account a 90% cost reduction for ezetimibe.  相似文献

Abstract

Aims: This article aimed to examine the cost-effectiveness of rivaroxaban in comparison to warfarin for stroke prevention in Japanese patients with non-valvular atrial fibrillation (NVAF), from a public healthcare payer’s perspective.

Materials and methods: Baseline event risks were obtained from the J-ROCKET AF trial and the treatment effect data were taken from a network meta-analysis. The other model inputs were extracted from the literature and official Japanese sources. The outcomes included the number of ischaemic strokes, myocardial infarctions, systemic embolisms and bleedings avoided, life-years, quality-adjusted life-years (QALYs), incremental costs and incremental cost-effectiveness ratio (ICER). The scenario analysis considered treatment effect data from the same network meta-analysis.

Results: In comparison with warfarin, rivaroxaban was estimated to avoid 0.284 ischaemic strokes per patient, to increase the number of QALYs by 0.535 per patient and to decrease the total costs by ¥118,892 (€1,011.11) per patient (1 JPY = 0.00850638 EUR; XE.com, 7 October 2019). Consequently, rivaroxaban treatment was found to be dominant compared to warfarin. In the scenario analysis, the ICER of rivaroxaban versus warfarin was ¥2,873,499 (€24,446.42) per QALY.

Limitations: The various sources of data used resulted in the heterogeneity of the cost-effectiveness analysis results. Although, rivaroxaban was cost-effective in the majority of cases.

Conclusion: Rivaroxaban is cost-effective against warfarin for stroke prevention in Japanese patients with NVAF, giving the payer WTP of 5,000,000 JPY.  相似文献

Abstract

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.  相似文献

Abstract

Objective:

The aim of this study was to determine the budget impact of everolimus (in combination with letrozole/anastrozole) as a second-line treatment for ER+ HER2? negative advanced and metastatic breast cancer in post-menopausal women.

Research design and methods:

A cumulative cohort model was developed to estimate the 5-year costs associated with introducing everolimus to the Kazakh healthcare system. Two alternative market share scenarios were compared: with everolimus and without everolimus. PFS and OS data were taken from the trial and extrapolated. The background costs of the pre-progressed and post-progressed health states, drug costs and costs associated with adverse events were included in the model.

Results:

The 5-year results from the budget impact analysis demonstrate that the introduction of everolimus leads to a 12% increase in drug costs, a 2% reduction in pre-progression health state costs, a 1% increase in post-progression health state costs, and a 2% reduction in adverse event costs. The net result is only a modest increase in total costs; a 2.69% increase of T201 million, from T7.5 billion to T7.7 billion over a period of 5 years.

Conclusions:

The analysis estimated that, if everolimus were to be introduced to the Kazakh healthcare market for the treatment of ER+ HER2? advanced breast cancer, there would be minimal impact upon overall healthcare expenditure. An increase in drug acquisitions costs was almost exactly offset by a reduction in other healthcare costs, due to improved management of the disease.  相似文献

Abstract

Objective: This study aimed to compare the cost-effectiveness of ramucirumab versus placebo for patients with hepatocellular carcinoma who progressed on sorafenib with α-fetoprotein concentrations (AFP) of at least 400?ng/ml in the United States.

Methods: A Markov model was constructed to assess the cost-effectiveness of ramucirumab. Health outcomes were measured as quality-adjusted life years (QALYs). With TreeAge software, the disease process was modeled as three health states: progression-free survival (PFS), progressive disease (PD), and death. Costs were extracted from the REACH-2 trial, and utility was derived from published literature. Incremental cost-effectiveness ratios (ICERs) were calculated to compare ramucirumab with placebo. Probabilistic sensitivity analyses were developed to examine the robustness of the results.

Results: In the base case analysis, ramucirumab therapy had a cost of $55,508.41 and generated 0.54 QALYs, while placebo therapy had a cost of $761.09 and generated 0.47 QALYs, leading to an additional $54,747.32 in costs and 0.07 QALYs. The ICER was $782,104.57 per QALY, which was much higher than the willingness-to-pay threshold of $100,000 per QALY. According to sensitivity analyses, the utility of PD in the two groups was the dominant parameter influencing the ICER.

Conclusion: Although ramucirumab was associated with prolonged survival for patients with advanced hepatocellular carcinoma who progressed on sorafenib treatment with an AFP of at least 400?ng/ml, it is not a cost-effective treatment from a United States payer perspective.  相似文献

Background:

Patients with unresectable, metastatic colorectal cancer with wild type Kirsten ras mutational status are eligible for sequential treatments which include monoclonal antibodies as first line (1L), second line (2L), or third line (3L) regimens.

Objective:

To compare the economic outcomes of different sequences which include monoclonal antibodies for the treatment of unresectable metastatic colorectal cancer.

Methods:

Individual drug regimens for 1L, 2L, and 3L treatments were compiled according to the clinical studies in the Summary of Product Characteristics for monoclonal antibodies. They were combined into plausible treatment sequences. Health outcomes were approximated using additive median PFS benefit, and economic outcomes were calculated with a treatment sequencing costing tool. Limitations of the analysis include the clinical trial data sources, cost assumptions, and the additive PFS approach.

Results:

Seventeen sequences were evaluated. Results of the analysis show that sequences including 1L anti-EGFRs generally have relatively low-to-medium health outcomes at the highest comparative sequence costs compared to sequences including 2L anti-EGFRs, which have lower health outcomes at the lowest cost. Sequences including 3L anti-EGFRs (sequential bevazicumab-based 1L and 2L) have the highest health outcomes, with potential cost savings of €5972–€11,676 if replacing 2L anti-EGFRs or an additional cost of €5909–€12,708 if replacing 1L anti-EGFR regimens.

Conclusion:

Clinical sequences consisting of 1L and 2L line bevacizumab followed by 3L anti-EGFR potentially yield the greatest health outcomes associated with a reasonable trade-off in additional cost when replacing 1L anti-EGFRs and are potentially cost-saving if replacing 2L anti-EGFRs, per patient per lifetime. To maximize health outcomes, optimal sequences include anti-EGFRs as 3L regimen, with an approximately equivalent trade-off in costs between the most costly (anti-EGFR 2L) and least costly (anti-EGFR 1L) sequences.  相似文献

Abstract

Objectives: To evaluate the cost-effectiveness of olmesartan/amlodipine fixed-dose combination vs olmesartan and amlodipine free combination, amlodipine single drug, and valsartan/amlodipine fixed-dose combination in the treatment of hypertensive patients from payer perspective in China.

Methods: A Markov model was constructed, which included five health states of hypertensive patients who are aged 35–84?years at baseline and free of cardiovascular disease. Clinical data were obtained from a network meta-analysis. Epidemiology data, adverse events (AEs), cost, and utility data were obtained from the literature. The cost associated with AEs was estimated based on the cost of same symptoms of hypertensive patients in an electric medical record database. The model projected quality-adjusted life years (QALYs) gained, total costs per patient in a 20-year time horizon, and incremental cost-effectiveness ratios. Probability sensitivity analyses (PSA) and one-way sensitivity analyses were conducted for the main parameters to test the robustness of the model.

Results: Compared to olmesartan and amlodipine free combination, amlodipine, and valsartan/amlodipine fixed-dose combination, treatment with olmesartan/amlodipine fixed-dose combination led to fewer CVD events and deaths; resulted in an incremental cost of ¥?5,439 ($?791.36), ¥6,530 ($950.09), and ¥?1,019 ($?148.26) and gained additional QALYs of 0.052, 0.094, and 0.037 per patient, respectively. Compared with olmesartan and amlodipine free combination and valsartan/amlodipine fixed-dose combination, olmesartan/amlodipine fixed-dose combination was dominant. Compared with amlodipine alone, the incremental cost-effectiveness ratios were below the WHO recommended cost-effectiveness threshold, indicating the olmesartan/amlodipine fixed-dose combination was a cost-effective option for hypertensive patients in China. The 10-years’ time horizon scenario analysis showed similar results to the 20-years’ time horizon. Probabilistic sensitivity analysis and one-way sensitivity analyses showed the robustness of the model results.

Conclusions: Olmesartan/amlodipine fixed-dose combination confers better health outcomes and costs less compared with olmesartan and amlodipine free combination and valsartan/amlodipine fixed-dose combination, and is cost-effective compared to amlodipine for hypertension treatment in China.  相似文献

Abstract

Objective: To assess the cost-utility of celecoxib in three treatment strategies for arthritis in Quebec, considering both upper gastrointestinal (GI) and cardiovascular (CV) events.

Methods: A Markov analytic framework was used to model patients with osteoarthritis and rheumatoid arthritis at low/average and high risk of GI and CV toxicity over 5 years with monthly cycles. Treatment strategies were modelled in line with Canadian clinical practice. In first-line treatment, patients started on celecoxib; second-line, patients started on a non-selective non-steroidal anti-inflammatory drug (NSAID) and switched to celecoxib after a first GI event; third-line, patients started on a non-selective NSAID, added a proton pump inhibitor (PPI) after a first GI event, and switched to celecoxib after a second GI event (while maintaining the PPI). Model inputs were determined through comprehensive literature searches (MEDLINE and EMBASE) from 1995 to 2006. Included studies evaluated GI (dyspepsia, uncomplicated and complicated ulcers, death) and CV (myocardial infarction, stroke, death) events. Drug and procedure costs were derived from Canadian published sources (Can$2005).

Results: Total costs per patient for celecoxib first-, second-, and third-line treatment were Can$4,790, $3,390, and $3,466, and total quality-adjusted life-years (QALY) were 3.251, 3.231, and 3.230, respectively. In all risk categories, celecoxib second-line was less costly and as effective as celecoxib third-line, producing savings to the healthcare system. Although celecoxib first-line generated incremental expenditures versus celecoxib second-line, it was also more effective. The resulting cost-utility ratio for the high-risk population was Can$54,696/QALY. Based on this analytical approach, a treatment strategy where celecoxib is used before the combination of a non-selective NSAID plus a PPI possesses cost advantages for the Quebec provincial drug programme. One-way sensitivity analysis (varying GI and CV event rates, utilities, and cost) generally showed second-line treatment with celecoxib as the dominant strategy compared with third-line treatment with celecoxib.

Conclusion: Although effectiveness of second- and third-line celecoxib use is similar, total cost is lower for second-line. These results suggest that the use of celecoxib before the combination of a non-selective NSAID plus a PPI is relatively cost-effective in the treatment of arthritis pain and support the full benefit listing of celecoxib in Quebec's drug programme.  相似文献

Abstract

Background and aims: A wide range of treatment options are available for hepatocellular carcinoma (HCC), including systemic treatment with tyrosine kinase inhibitors (TKIs) such as sorafenib and lenvatinib, immunotherapies, locoregional therapies such as selective internal radiation therapy (SIRT) and treatments with curative intent such as resection, radiofrequency ablation and liver transplantation. Given the substantial economic burden associated with HCC treatment, the aim of the present analysis was to establish the cost of using SIRT with SIR-Spheres yttrium-90 (Y-90) resin microspheres versus TKIs from healthcare payer perspectives in France, Italy, Spain and the United Kingdom (UK).

Methods: A cost model was developed to capture the costs of initial systemic treatment with sorafenib (95%) or lenvatinib (5%) versus SIRT in patients with HCC in Barcelona Clinic Liver Cancer (BCLC) stages B and C. A nested Markov model was utilized to model transitions between progression-free survival (PFS), progression and death, in addition to transitions between subsequent treatment lines. Cost and resource use data were identified from published sources in each of the four countries.

Results: Relative to TKIs, SIRT with SIR-Spheres Y-90 resin microspheres were found to be cost saving in all four country settings, with the additional costs of the microspheres and the SIRT procedure being more than offset by reductions in drug and drug administration costs, and treatment of adverse events. Across the four country settings, total cost savings with SIR-Spheres Y-90 resin microspheres fell within the range 5.4–24.9% and SIRT resulted in more patients ultimately receiving treatments with curative intent (4.6 vs. 1.4% of eligible patients).

Conclusion: SIR-Spheres Y-90 resin microspheres resulted in cost savings relative to TKIs in the treatment of unresectable HCC in all four country settings, while increasing the proportion of patients who become eligible for treatments with curative intent.  相似文献

Abstract

Objectives:

Advances in survival in multiple myeloma have focused payer attention on the cost of care. An assessment was conducted to compare the costs of two recent treatments for relapsed/refractory multiple myeloma (rrMM), from the perspective of a US payer.

Methods:

An economic model estimated the total costs of care for two guideline-recommended therapies in rrMM patients: bortezomib (BORT) and lenalidomide plus dexamethasone (LEN/DEX). To evaluate total treatment costs, the costs associated with drug treatment, medical resource utilization, and adverse event (AE) management were determined for each regimen over a common 1-year period. Medical costs and grade 3/4 AE costs were based on rates from published literature, package inserts, and fee schedules (US dollars). To evaluate cost per outcome, assessments determined the monthly costs without disease progression based on pivotal clinical trials (APEX [BORT] and MM-009/MM-010 [LEN/DEX]). Univariate sensitivity analyses and alternative scenarios were also conducted.

Results:

Drug costs for the treatments were very similar, differing by under $10 per day. Medical and AE management costs for BORT were higher by more than $40 per day. Treatment with BORT had annual excess total costs of >$17,000 compared with LEN/DEX. A cost advantage for LEN/DEX was maintained across a variety of sensitivity analyses. Total cost per month without progression was 11% lower with LEN/DEX.

Limitations:

This analysis relied on separate studies having similar comparators, populations, and end-points. Actual treatment patterns and costs pre- and post-relapse may vary from the base scenario and sensitivities modeled. The 12-month time frame captures the preponderance of costs for a relapse line of therapy, yet may not reflect the entirety of costs. There is insufficient evidence to determine whether, or how, a difference in the lifetime costs of the two regimens would vary from the 1-year cost difference.

Conclusion:

While rrMM treatment with BORT and LEN/DEX had comparable drug costs, total treatment costs for BORT were higher due to ongoing direct medical and AE management costs. Total costs per outcome (a month without disease progression) were lower for LEN/DEX.  相似文献

Background: EOX (epirubicin, oxaliplatin, Xeloda; capecitabine) and FOLFOX4 (5-fluorouracil (5-FU), leucovorin, oxaliplatin) are the common chemotherapy regimens used in the treatment of advanced gastric cancer (aGC) in Hong Kong. This study aimed to compare the costs of these therapies for aGC patients from both the healthcare and societal perspectives. It should be noted that, while FOLFOX4 is routinely administered in an outpatient setting in North America and Europe, inpatient setting is adopted in Hong Kong instead, incurring hospitalization cost as a result.

Methods: Fifty-eight patients were identified from the electronic records in two public tertiary hospitals, with 45 and 13 receiving EOX and FOLFOX4 regimens, respectively. Healthcare cost was direct medical costs including drugs, clinic follow-up, hospitalization, diagnostic laboratories, and radiographs. Societal cost refers to indirect costs such as patient time and travel costs. Cost items were further classified as “expected” or “unexpected”. All cost data was expressed in US dollars.

Results: Patients in the EOX and FOLFOX4 arm received an average of 5.3 and 7.8 cycles of treatment, respectively. The capecitabine-based regimen group had a higher expected medication cost per cycle when compared to the 5-FU-based treatment group (US$290.3 vs US$66.9, p?p?p?p?=?.001), respectively, in the capecitabine-based regimen group. Sensitivity analyses based on full cycle regimen costs and net capecitabine or 5-FU/leucovorin costs still showed EOX to be less costly than FOLFOX4.

Conclusion: The capecitabine-based regimen, EOX, was found to generate significant cost saving from both the healthcare and societal perspectives in regions in which FOLFOX4 is given in an inpatient setting.  相似文献

Abstract

Aims: To evaluate total costs and health consequences of a colorectal cancer (CRC) screening program with colonoscopy, fecal immunochemical tests (FIT), and expanded use of multitarget stool DNA (mt-sDNA) from the perspectives of Integrated Delivery Networks (IDNs) and payers in the United States.

Materials and methods: We developed a budget impact and cost-consequence model that simulates CRC screening for eligible 50- to 75-year-old adults. A status quo scenario and an increased mt-sDNA scenario were modeled. The status quo includes the current screening mix of colonoscopy (83%), FIT (11%), and mt-sDNA (6%) modalities. The increased mt-sDNA scenario increases mt-sDNA utilization to 28% over 10 years. Costs for both the IDN and the payer perspectives incorporated diagnostic and surveillance colonoscopies, adverse events (AEs), and CRC treatment. The IDN perspective included screening program costs, composed of direct nonmedical (e.g. patient navigation) and indirect (e.g. administration) costs. It was assumed that IDNs do not incur the costs for stool-based screening tests or bowel preparation for colonoscopies.

Results: In a population of one million covered lives, the 10-year incremental cost savings incurred by increasing mt-sDNA utilization was $16.2 M for the IDN and $3.3 M for the payer. The incremental savings per-person-per-month were $0.14 and $0.03 for the IDN and payer, respectively. For both perspectives, increased diagnostic colonoscopy costs were offset by reductions in screening colonoscopies, surveillance colonoscopies, and AEs. Extending screening eligibility to 45- to 75-year-olds slightly decreased the overall cost savings.

Limitations: The natural history of CRC was not simulated; however, many of the utilized parameters were extracted from highly vetted natural history models or published literature. Direct nonmedical and indirect costs for CRC screening programs are applied on a per-person-per modality basis, whereas in reality some of these costs may be fixed.

Conclusions: Increased mt-sDNA utilization leads to fewer colonoscopies, less AEs, and lower overall costs for both IDNs and payers, reducing overall screening program costs and increasing the number of cancers detected while maintaining screening adherence rates over 10 years.  相似文献

Abstract

Background:

Pancreatic adenocarcinoma has few effective treatment options and poor survival. The objective of this study was to characterize treatment patterns and estimate the costs and resource use associated with its treatment in a commercially-insured US population.

Methods:

In this retrospective claims-based analysis, individuals ≥18 years old with evidence of pancreatic adenocarcinoma between January 1, 2001 and December 31, 2010 were selected from a managed care database. Treatment phase (either initial non-metastatic or metastatic) was determined using a claims-based algorithm. Patients in the pancreatic cancer population were matched 1:3 to a control population. Resource use (events/person-years), treatment patterns, and healthcare costs (per-patient per-month, PPPM) were determined during a variable length follow-up period (from first pancreatic cancer diagnosis to earliest of death, disenrollment, or study end).

Results:

In this study, 5262 pancreatic cancer patients were matched to 15,786 controls. Rates of office visits, inpatient visits, ER visits, and inpatient stays, and mean total all-cause healthcare costs PPPM ($15,480 vs $1001) were significantly higher among cancer patients than controls (all p?<?0.001). Mean inpatient costs were the single largest cost driver ($9917 PPPM). Also, mean total all-cause healthcare costs were significantly higher during the metastatic treatment phase vs the initial treatment phase of non-metastatic disease ($21,637 vs $10,358, p?<?0.001).

Conclusions:

These results indicate that pancreatic cancer imposes a substantial burden on the US healthcare system, and that treatment of more advanced disease is significantly more costly than initial treatment of non-metastatic disease.

Limitations:

Additional research is needed to validate the accuracy of the claims-based algorithms used to identify the treatment phase.  相似文献

Background: Trastuzumab was considered a cost-effective adjuvant treatment for HER 2-positive early breast cancer. Since 2010, the Taiwanese National Health Insurance (NHI) has started to reimburse for 1-year adjuvant treatment. This study aims to provide an updated cost-effectiveness analysis from the NHI perspective, which explores assumptions about long-term cardiac toxicity and treatment benefit of 1-year adjuvant treatment sequentially after chemotherapy.

Methods: A Markov model was used to evaluate the cost-effectiveness of 1-year adjuvant trastuzumab for HER-2/neu positive early breast cancer over a 20-year life-time horizon. A probability sensitivity analysis using Monte Carlo simulation was performed to characterize uncertainties in the expected outcomes, which are expressed as an incremental costs effectiveness ratio (ICER, cost/QALY). A willingness-to-pay threshold of 3-times the per capita gross domestic product was adopted according to the WHO definition. The Taiwan per capita gross domestic product in 2015 was US$22,355; thus, a threshold was considered as NT$2,011,950 (US$67 065, 1USD?=30 NTD in 2015).

Results: The model showed that adjuvant trastuzumab treatment in HER-2/neu positive early breast cancer yielded 1.631 quality-adjusted life-years (QALY) compared with no trastuzumab treatment. The ICER was US $51,863 per QALY gained in the base-case scenario. The Monte Carlo simulation by varying all variables simultaneously demonstrated that the probability of cost-effectiveness at the willingness-to-pay threshold of US$67,065 was 50% for 1-year adjuvant trastuzumab.

Conclusions: From this real-world study, 1-year adjuvant trastuzumab treatment is likely to be a cost-effective therapy for patients with HER-2 positive breast cancer at the willingness-to-pay threshold of 3-times GDP per capita in Taiwan.  相似文献
