RESUMO

PURPOSE: To evaluate the cost-effectiveness of tucatinib in human epidermal growth factor receptor 2 (HER2)-positive breast cancer (BC) patients with brain metastases (BMs) and the subgroup of active BMs from the United States (US) payer perspective. MATERIALS AND METHODS: A 3-state Markov model was developed to compare the cost-effectiveness of 2 regimens in HER2-positive BC patients with BMs: (1) tucatinib, trastuzumab, and capecitabine (TTC); (2) placebo, trastuzumab, and capecitabine (PTC). And subgroup analysis of active BMs was also performed. Lifetime costs, quality-adjusted life years (QALYs), incremental cost-effectiveness ratio (ICER) and incremental net-health benefit (INHB) were estimated. The willingness-to-pay (WTP) threshold was $200,000/QALY. The robustness of the model was tested by sensitivity analyses. Additional scenario analysis was also performed. RESULTS: Compared with PTC, the ICER yielded by TTC was $418,007.01/QALY and the INHB was -1.08 QALYs in patients with BMs. In the subgroup of active BMs, the ICER and the INHB were $324,465.03/QALY and -0.71 QALY, respectively. The results were most sensitive to the cost of tucatinib. Probabilistic sensitivity analyses suggested that the cost-effective probability of TTC was low at the current WTP threshold in the patients with BMs and the subgroup of active BMs. CONCLUSION: Tucatinib is unlikely to be cost-effective in HER2-positive BC patients with BMs from the US payer perspective but shows better economics in patients with active BMs. Selecting a favorable population, reducing the price of tucatinib or offering appropriate drug assistance policies might be considerable options to optimize the cost-effectiveness of tucatinib.

RESUMO

OBJECTIVES: The aim of this study is to assess the cost-effectiveness of fruquintinib compared to regorafenib as third-line treatment for patients with metastatic colorectal cancer (mCRC) in China. METHODS: A three-state Markov model with monthly cycle was constructed to estimate lifetime incremental cost-effectiveness ratio (ICER) of fruquintinib versus regorafenib as third-line treatment for patients with mCRC from Chinese health care perspective. Survival analysis was applied to calculate transition probabilities using the data from the clinical trials FRESCO and CONCUR, which were also the data sources accessing probabilities of adverse events. Background mortality rate and drug costs were derived from government published data. Costs for medical services were obtained from real-world data and published literatures. Utilities applied to calculate the quality-adjusted life years (QALYs) were obtained from literature review. One-way sensitivity analysis and probabilistic sensitivity analysis were adopted to verify the robustness of the results. RESULTS: Fruquintinib provided 0.74 QALYs at a cost of CNY 151,058 (USD 22,888), whereas regorafenib provided 0.79 QALYs at a cost of CNY 226,657 (USD 32,224). Compared to fruquintinib, the ICER of regorafenib was CNY 1,529,197/QALY (USD 231,697/QALY) from Chinese health care perspective, which was above the triple GDP per capita of China in 2019 (CNY 212,676) (USD 32,224) as the threshold to define the cost-effectiveness. One-way sensitivity analysis showed the results were generally robust. Cost-effectiveness acceptability curves derived from probabilistic sensitivity analysis demonstrated the probability that fruquintinib was more cost-effective was 100% when the threshold was the triple GDP per capita of China. CONCLUSIONS: Compared to regorafenib, fruquintinib, which leads to forego about 0.05 QALYs and save about CNY 75,599 (USD 11,454), is a cost-effective choice as the third-line treatment for patients with mCRC in China.

RESUMO

PURPOSE: Nonsmall cell lung cancer (NSCLC) patients with brain metastases (BM) have a poor prognosis. Despite the traditional methods including radiotherapy and chemotherapy, epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) might benefit patients on survival and quality of life. We investigated the cost-effectiveness of icotinib compared with whole-brain irradiation (WBI) with or without chemotherapy for NSCLC patients with BM. MATERIALS AND METHODS: A Markov model was conducted based on the data of BRAIN trial. We compared the economic benefit between icotinib and the combination of WBI and WBI plus chemotherapy group. We considered disease progression as intracranial progression and overall progression separately. Sensitivity analyses were performed to observe the stability of the model. The willingness-to-pay (WTP) was set as 3× per capita gross domestic product ($25929/quality-adjusted life year [QALY]) from the Chinese healthcare perspective. RESULTS: When considering progression as intracranial progression and overall progression, respectively, the incremental cost-effectiveness ratio was $14 882.64/QALY and $13 484.21/QALY between icotinib and WBI/WBI-chemotherapy. Besides, both of the average cost-effective ratio (ACER) and net benefit showed advantage of icotinib (ACER: $34 521.42/QALY for intracranial progression and $36 562.63/QALY for overall progression; net benefit: -$8407.36 for intracranial progression and -$9836.41 for overall progression). One-way sensitivity analyses demonstrated that no thresholds were encountered. The probabilistic sensitivity analyses showed even at a WTP under $18 000/QALY, icotinib could be cost-effective. CONCLUSION: Icotinib was cost-effective compared with WBI with or without chemotherapy.

RESUMO

To evaluate the cost-effectiveness of letermovir versus no prophylaxis for the prevention of cytomegalovirus infection and disease in adult cytomegalovirus-seropositive allogeneic hematopoietic cell transplantation (allo-HCT) recipients. A decision model for 100 patients was developed to estimate the probabilities of cytomegalovirus infection, cytomegalovirus disease, various other complications, and death in patients receiving letermovir versus no prophylaxis. The probabilities of clinical outcomes were based on the pivotal phase 3 trial of letermovir use for cytomegalovirus prophylaxis versus placebo in adult cytomegalovirus-seropositive recipients of an allo-HCT. Costs of prophylaxis with letermovir and of each clinical outcome were derived from published sources or the trial clinical study reports. Incremental cost-effectiveness ratios (ICERs) in terms of cost per quality-adjusted life year (QALY) gained were used in the model. One-way and probabilistic sensitivity analyses were conducted to explore uncertainty around the base-case analysis. In this model, the use of letermovir prophylaxis would lead to an increase of QALYs (619) and direct medical cost ($1 733 794) compared with no prophylaxis (578 QALYs; $710 300) in cytomegalovirus-seropositive recipients of an allo-HCT. Letermovir use for cytomegalovirus prophylaxis was a cost-effective option versus no prophylaxis with base-case analysis ICER $25 046/QALY gained. One-way sensitivity analysis showed the most influential parameter was mortality rate. The probabilistic sensitivity analysis showed a 92% probability of letermovir producing an ICER below the commonly accepted willingness-to-pay threshold of $100 000/QALY gained. Based on this model, letermovir use for cytomegalovirus prophylaxis was a cost-effective option in adult cytomegalovirus-seropositive recipients of an allo-HCT.

RESUMO

BACKGROUND: In this study, we analyze the cost-effectiveness of fruquintinib as third-line treatment for patients with metastatic colorectal cancer in China, especially after a recent price drop suggested by the National Healthcare Security Administration. METHODS: A Markov model was developed to investigate the cost-effectiveness of fruquintinib compared to placebo among patients with metastatic colorectal cancer. Effectiveness was measured in quality-adjusted life years (QALY). The Chinese healthcare payer's perspective was considered with a lifetime horizon, including direct medical cost (2019 US dollars [USD]). A willing-to-pay threshold was set at USD 27,130/QALY, which is three times the gross domestic product (GDP) per capita. We examined the robustness of the model in one-way and probabilistic sensitivity analysis. RESULTS: Fruquintinib was associated with better health outcomes than placebo (0.640 vs 0.478 QALYs) with a higher cost (USD 20750.9 vs USD 12042.2), resulting in an incremental cost-effectiveness ratio (ICER) of USD 53508.7 per QALY. This ICER is 25% lower than the one calculated before the price drop (USD 70952.6 per QALY). CONCLUSION: After the price negotiation, the drug becomes cheaper and the ICER is lower, but the drug is still not cost effective under the standard of 3 times GDP willing-to-pay threshold. For patients with metastatic colorectal cancer in China, fruquintinib is not a cost-effective option under the current circumstances in China.

RESUMO

OBJECTIVE: To evaluate the cost-effectiveness of addition of fruquintinib to best supportive care (BSC) in third-line treatment for patients with metastatic colorectal cancer (CRC). METHODS: To conduct the cost-effectiveness analysis, a Markov model was established to simulate the course of metastatic CRC. Three health states-progression-free survival (PFS), progressive disease (PD), and death-were included. Clinical data were derived from the FRESCO trial and health utility values were extracted from previous literature. The primary outcome of the study was incremental cost-effectiveness ratio (ICER) in US dollars per quality-adjusted life-years (QALYs) from a Chinese societal perspective. One-way sensitivity analyses and probabilistic sensitivity analyses were performed to test the robustness of the study. RESULTS: Addition of fruquintinib to BSC gained 0.54 QALY at a cost of $15,404.57 while the BSC group gained 0.38 QALY at a cost of $9603.94. ICER of fruquintinib versus BSC was $36,253.94/QALY. In the 1-way sensitivity analyses, utility for PD in both groups, utility for PFS in both groups, and cost of fruquintinib significantly influenced the results of the analysis. At the willingness-to-pay threshold of $28,988.40/QALY, probabilities of addition of fruquintinib to BSC or BSC alone as the cost-effective option were 0% and 100%, indicating addition of fruquintinib is not a dominant option compared with BSC. CONCLUSIONS: Addition of fruquintinib to BSC is not a cost-effective regimen in the third-line setting for patients with metastatic CRC from the Chinese societal perspective.

RESUMO

ABSTRACT BACKGROUND: Lung cancer is the fourth most common cancer in Brazil. In the 2000s, better understanding of molecular pathways led to development of epidermal growth factor receptor (EGFR)-targeted treatments that have improved outcomes. However, these treatments are unavailable in most Brazilian public healthcare services (Sistema Único de Saúde, SUS). OBJECTIVE: To assess the potential number of years of life not saved, the budget impact of the treatment and strategies to improve access. DESIGN AND SETTING: Pharmacoeconomic study assessing the potential societal and economic impact of adopting EGFR-targeted therapy within SUS. METHODS: We estimated the number of cases eligible for treatment, using epidemiological data from the National Cancer Institute. We used data from a single meta-analysis and from the Lung Cancer Mutation Consortium (LCMC) study as the basis for assessing differences in patients' survival between use of targeted therapy and use of chemotherapy. The costs of targeted treatment were based on the national reference and were compared with the amount reimbursed for chemotherapy through SUS. RESULTS: There was no life-year gain with EGFR-targeted therapy in the single meta-analysis (hazard ratio, HR, 1.01). The LCMC showed that 1,556 potential life-years were not saved annually. We estimated that the annual budget impact was 125 million Brazilian reais (BRL) with erlotinib, 48 million BRL with gefitinib and 52 million BRL with afatinib. Their incremental costs over chemotherapy per life-year saved were 80,329 BRL, 31,011 BRL and 33,225 BRL, respectively. A drug acquisition discount may decrease the budget impact by 30% (with a 20% discount). A fixed cost of 1,000 BRL may decrease the budget impact by 95%. CONCLUSION: Reducing drug acquisition costs may improve access to EGFR-targeted therapy for lung cancer.

RESUMO

BACKGROUND: Afatinib is 1 of 3 tyrosine kinase inhibitors approved in the United States for the first-line treatment of patients with metastatic non-small cell lung cancer (NSCLC) whose tumors have epidermal growth factor receptor (EGFR) exon 19 deletions (del19) or exon 21 (L858R) substitution mutations. In clinical trials, afatinib has demonstrated improvement in progression-free survival versus standard chemotherapy and gefitinib. OBJECTIVE: To analyze the impact of increases in afatinib treatment share on the cost and health outcomes in a commercial health plan in the United States. METHODS: A decision model was developed to evaluate the budget impact of increases in afatinib share for the first-line treatment of patients with metastatic NSCLC with EGFR del19 or L858R substitution mutations over a 5-year time horizon. The model compared the total annual costs for a health plan with 1 million covered lives in a scenario in which afatinib share increased 5 percentage points annually to one in which all treatment shares remained constant over time. The number of patients eligible for treatment was estimated using published incidence data. Therapies included in the model were afatinib, erlotinib, gefitinib, and the chemotherapy doublet, pemetrexed in combination with cisplatin. The mean time spent by patients in progression-free and progressive disease states was based on survival data from clinical trials and a network meta-analysis. Therapy-related costs included monthly drug acquisition and administration costs and costs of managing adverse reactions. Disease management costs were also assessed in the model. Scenario analyses were performed to assess alternative scenarios of afatinib treatment share. Additionally, a one-way sensitivity analysis was performed to test the robustness of the model, given parameter uncertainty. RESULTS: Using the base-case parameter assumptions and a 5-percentage-point annual increase in afatinib treatment share, we estimated the total budget increases in years 1 through 5 to be $1,606, $65,542, $140,564, $209,272, and $303,368, respectively. These budget increases translated to per-member-per-month increases ranging from $0.00 to $0.03 in years 1 to 5. The increase in afatinib use resulted in the proportion of the treated population (134 patients treated over 5 years) remaining in progression-free disease increasing from 23.7% to 26.2% at the end of year 5, versus if afatinib treatment share had stayed constant. CONCLUSIONS: Increasing the treatment share of afatinib in a health plan for the first-line treatment of NSCLC with EGFR del19 or L858R mutations was estimated to increase the proportion of treated patients remaining in progression-free disease, while having small budget impact to the health plan.

RESUMO

INTRODUCTION: The irreversible ErbB family blocker afatinib and the reversible EGFR tyrosine kinase inhibitor gefitinib were compared in the multicenter, international, randomized, head-to-head phase 2b LUX-Lung 7 trial for first-line treatment of advanced EGFR mutation-positive NSCLCs. Afatinib and gefitinib costs and patients' outcomes in France were assessed. METHODS: A partitioned survival model was designed to assess the cost-effectiveness of afatinib versus gefitinib for EGFR mutation-positive NSCLCs. Outcomes and safety were taken primarily from the LUX-Lung 7 trial. Resource use and utilities were derived from that trial, an expert-panel questionnaire, and published literature, limiting expenditures to direct costs. Incremental cost-effectiveness ratios (ICERs) were calculated over a 10-year time horizon for the entire population, and EGFR exon 19 deletion or exon 21 L858R mutation (L858R) subgroups. Deterministic and probabilistic sensitivity analyses were conducted. RESULTS: For all EGFR mutation-positive NSCLCs, the afatinib-versus-gefitinib ICER of was €45,211 per quality-adjusted life-year (QALY) (0.170 QALY gain for an incremental cost of €7697). ICERs for EGFR exon 19 deletion and L858R populations were €38,970 and €52,518, respectively. Afatinib had 100% probability to be cost-effective at a willingness-to-pay threshold of €70,000/QALY for patients with common EGFR mutations. CONCLUSION: First-line afatinib appears cost-effective compared with gefitinib for patients with EGFR mutation-positive NSCLCs.

RESUMO

BACKGROUND: The New Zealand Pharmaceutical Management Agency (PHARMAC) approved funding of erlotinib in October 2010 as second line therapy in all non-squamous non-small cell lung cancer after platinum-based chemotherapy with no requirement for epidermal growth factor (EGFR) mutation testing. Funding widened in August 2012 to include gefitinib as first line treatment for patients with a proven EGFR mutation. Then in January 2014, both tyrosine kinase inhibitors (TKIs) were approved for first line treatment, but only for disease with EGFR mutation. AIM: To report the clinical experience with TKIs in a New Zealand tertiary referral centre over a period of funding change. METHOD: Retrospective audit of all patients commenced on erlotinib from 1st October 2010 until 1st November 2011, and gefitinib from 1st August 2012 until 31st August 2013. Follow-up was two years for both groups. RESULTS: Each group had 42 patients. Median Progression Free Survival was 76 days in the erlotinib group and 255 days in the gefitinib group. Twenty-eight percent of erlotinib patients had grade 3 adverse events with one treatment related death; fourteen percent of gefitinib patients had grade 3 adverse events. Dose reduction or treatment breaks were required in 12% in each group. CONCLUSION: Response rate in these audits appear to reflect the change in funding criteria, with improved response rates likely to be associated with more targeted treatment.

RESUMO

OBJECTIVES: The aim of this study was to estimate lowest possible treatment costs for four novel cancer drugs, hypothesising that generic manufacturing could significantly reduce treatment costs. SETTING: This research was carried out in a non-clinical research setting using secondary data. PARTICIPANTS: There were no human participants in the study. Four drugs were selected for the study: bortezomib, dasatinib, everolimus and gefitinib. These medications were selected according to their clinical importance, novel pharmaceutical actions and the availability of generic price data. PRIMARY AND SECONDARY OUTCOME MEASURES: Target costs for treatment were to be generated for each indication for each treatment. The primary outcome measure was the target cost according to a production cost calculation algorithm. The secondary outcome measure was the target cost as the lowest available generic price; this was necessary where export data were not available to generate an estimate from our cost calculation algorithm. Other outcomes included patent expiry dates and total eligible treatment populations. RESULTS: Target prices were £411 per cycle for bortezomib, £9 per month for dasatinib, £852 per month for everolimus and £10 per month for gefitinib. Compared with current list prices in England, these target prices would represent reductions of 74-99.6%. Patent expiry dates were bortezomib 2014-22, dasatinib 2020-26, everolimus 2019-25 and gefitinib 2017. The total global eligible treatment population in 1 year is 769 736. CONCLUSIONS: Our findings demonstrate that affordable drug treatment costs are possible for novel cancer drugs, suggesting that new therapeutic options can be made available to patients and doctors worldwide.

RESUMO

Tyrosine kinase inhibitors of the epidermal growth factor receptor (EGFR) are becoming the standard treatment option for patients with advanced non-small cell lung cancer (NSCLC) harboring an EGFR mutation, but the economic impact of this practice is unclear, especially in a health resource-limited setting. A decision-analytic model was developed to simulate 21-day patient transitions in a 10-year time horizon. The health and economic outcomes of four first-line strategies (pemetrexed plus cisplatin [PC] alone, PC followed by maintenance with pemetrexed, or initial treatment with gefitinib or icotinib) among patients harboring EGFR mutations were estimated and assessed via indirect comparisons. Costs in the Chinese setting were estimated. The primary outcome was the incremental cost-effectiveness ratio (ICER). Sensitivity analyses were performed. The icotinib strategy resulted in greater health benefits than the other three strategies in NSCLC patients harboring EGFR mutations. Relative to PC alone, PC followed by pemetrexed maintenance, gefitinib and icotinib resulted in ICERs of $104,657, $28,485 and $19,809 per quality-adjusted life-year gained, respectively. The cost of pemetrexed, the EGFR mutation prevalence and the utility of progression-free survival were factors that had a considerable impact on the model outcomes. When the icotinib Patient Assistance Program was available, the economic outcome of icotinib was more favorable. These results indicate that gene-guided therapy with icotinib might be a more cost-effective treatment option than traditional chemotherapy.

RESUMO

INTRODUCTION: To examine the magnitude of the clinical benefit from first-line tyrosine kinase inhibitors (TKIs) advanced non-small cell lung cancer (NSCLC) with activating epidermal growth factor receptor (EGFR)-mutations. Areas covered: The present evaluation was restricted to pivotal phase III RCTs in first-line for advanced NSCLC with activating EGFR-mutations. We have subsequently applied the European Society for Medical Oncology-Magnitude of Clinical Benefit Scale (ESMO-MCBS) to the above pivotal phase III RCTs, to derive a relative ranking of the magnitude of clinically meaningful benefit. Our study evaluated 8 phase III RCTs (including 1710 patients). The ESMO-MCBS reached high grade (grade 4) for all TKIs treatments with at least one phase III RCT for each TKI. Expert commentary: Combining pharmacological costs of drugs with the measure of efficacy, afatinib has the lowest difference in costs per month-PFS gained and a comparable high grade of magnitude of clinical benefit.

RESUMO

BACKGROUND: In 2011 the first payment-by-results (PbR) scheme in Catalonia was signed between the Catalan Institute of Oncology (ICO), the Catalan Health Service, and AstraZeneca (AZ) for the introduction of gefitinib in the treatment of advanced EGFR-mutation positive non-small-cell lung cancer. The PbR scheme includes two evaluation points: at week 8, responses, stabilization and progression were evaluated, and at week 16 stabilization was confirmed. AZ was to reimburse the total treatment cost of patients that failed treatment, defined as progression at weeks 8 or 16. OBJECTIVE: To estimate the financial consequences of this PbR reimbursement model and determine the perception of the stakeholders involved in the agreement. METHODS: Differential drug costs between two scenarios, with and without the PbR, were calculated. A qualitative investigation of the organizational elements was performed by interviewing the parties involved in the agreement. RESULTS: Forty-one patients were included from June 2011 to October 2013 and assessed at two evaluation points. Clinical results were comparable to those observed in the pivotal studies of gefitinib. The difference in the cost of gefitinib using the PbR compared to the traditional purchasing scenario was 6.17% less at 8 weeks, 11.18% at 16 weeks and 4.15% less for the overall treatment. The PbR resulted in total savings of around €36,000 (€880 per patient). From an operational and organizational perspective, the availability of adequate data systems to measure outcomes and monitor accountability and the involvement of healthcare professionals were acknowledged as crucial. CONCLUSIONS: Tangible and intangible benefits were identified with respect to the interests of the parties involved. This has led to the incorporation of innovation for patients under acceptable conditions.

RESUMO

PURPOSE: The EMILIA trial demonstrated that trastuzumab emtansine (T-DM1) significantly increased the median profession-free and overall survival relative to combination therapy with lapatinib plus capecitabine (LC) in patients with HER2-positive advanced breast cancer (ABC) previously treated with trastuzumab and a taxane. We performed an economic analysis of T-DM1 as a second-line therapy compared to LC and monotherapy with capecitabine (C) from both perspectives of the US payer and society. METHODS: We developed four possible Markov models for ABC to compare the projected life-time costs and outcomes of T-DM1, LC, and C. Model transition probabilities were estimated from the EMILIA and EGF100151 clinical trials. Direct costs of the therapies, major adverse events, laboratory tests, and disease progression, indirect costs (productivity losses due to morbidity and mortality), and health utilities were obtained from published sources. The models used 3 % discount rate and reported in 2015 US dollars. Probabilistic sensitivity analysis and model averaging were used to account for model parametric and structural uncertainty. RESULTS: When incorporating both model parametric and structural uncertainty, the resulting incremental cost-effectiveness ratios (ICER) comparing T-DM1 to LC and T-DM1 to C were $183,828 per quality-adjusted life year (QALY) and $126,001/QALY from the societal perspective, respectively. From the payer's perspective, the ICERs were $220,385/QALY (T-DM1 vs. LC) and $168,355/QALY (T-DM1 vs. C). CONCLUSIONS: From both perspectives of the US payer and society, T-DM1 is not cost-effective when comparing to the LC combination therapy at a willingness-to-pay threshold of $150,000/QALY. T-DM1 might have a better chance to be cost-effective compared to capecitabine monotherapy from the US societal perspective.

RESUMO

BACKGROUND AND OBJECTIVE: Appropriate pricing of medications is one of the ultimate goals for decision makers, but reliable data on the risk/benefit ratio are often lacking when a Marketing Authorization Application is submitted. Here we propose a method to consistently evaluate price adequacy, which we applied to six anticancer medications approved in Italy in recent years. METHODS: We obtained ratios of cost per survival per day (cost/survival/day) by dividing the total costs of evaluated medications for the median survival gain in days. Each cost/survival/day corresponds to a crude score, with 0 assigned to a cost/survival/day ≥€586. The maximum price considered as adequate was €91 cost/survival/day (score 75) while a score of 100 corresponded to a cost/survival/day ≤€11, based on the thresholds set by the British National Health System (NHS) and the "willingness-to-pay" of the Italian NHS. Crude scores were then adjusted using correction factors for efficacy, safety, quality of life, and prevalence of disease. RESULTS: None of the analyzed medications (abiraterone, afatinib, aflibercept, bevacizumab, dabrafenib, and ipilimumab) achieved a final score of 75, corresponding to adequate pricing. The final score for afatinib was the highest with 55 points. Prices of all the other drugs resulted in being inadequate, with negative final scores for bevacizumab, dabrafenib, and ipilimumab. CONCLUSIONS: This method may be considered a tool for the evaluation of appropriateness of price proposed at negotiation and could represent a reliable resource for decision-making. Furthermore, this analysis suggests that most recently approved cancer drugs in Italy do not fulfill price adequacy.

RESUMO

Epidermal growth factor receptor gene (EGFR) mutation status has emerged as a crucial issue in lung cancer management. Availability and cost of tests and tyrosine kinase inhibitors (TKIs) may vary as a function of country development.We conducted a prospective specialist opinion survey to map EGFR test and EGFR-TKI availability and detect associations with the Human Development Index (HDI). A questionnaire was sent to specialists in thoracic oncology in all United Nations Member States.We obtained responses from 74 countries, comprising 78% of the worldwide population. Nonresponding countries had significantly lower HDI rank than responding countries. EGFR mutation analysis was routinely available in 57 countries (70% of the worldwide population). The cost of the test was

RESUMO

BACKGROUND: Our objective is to compare the cost-utility of icotinib and gefitinib for the second-line treatment of advanced non-small cell lung cancer (NSCLC) from the perspective of the Chinese healthcare system. METHODS: Model technology was applied to assess the data of randomized clinical trials and the direct medical costs from the perspective of the Chinese healthcare system. Five-year quality-adjusted life years (QALYs) and incremental cost-utility ratios (ICURs) were calculated. One-way and probabilistic sensitivity analyses (PSA) were performed. RESULTS: Our model suggested that the median progression-free survival (PFS) was 4.2 months in the icotinib group and 3.5 months in the gefitinib group while they were 4.6 months and 3.4 months, respectively, in the trials. The 5-year QALYs was 0.279 in the icotinib group and 0.269 in the gefitinib group, and the according medical costs were $10662.82 and $13127.57. The ICUR/QALY of icotinib versus gefitinib presented negative in this study. The most sensitive parameter to the ICUR was utility of PFS, ranging from $-1,259,991.25 to $-182,296.61; accordingly the icotinib treatment consistently represented a dominant cost-utility strategy. CONCLUSIONS: The icotinib strategy, as a second-line therapy for advanced NSCLC patients in China, is the preferred strategy relative to gefitinib because of the dominant cost-utility. In addition, icotinib shows a good curative effect and safety, resulting in a strong demand for the Chinese market.
