Medication adherence among patients with advanced prostate cancer using oral therapies.

Aims: In light of the extended overall survival and improved quality of life provided by advanced prostate cancer (PC) oral therapies, this study aimed to describe treatment adherence to advanced PC oral therapies and evaluate associated patient characteristics and subsequent healthcare resource utilization (HRU). Patients & methods: Patients with advanced PC initiating apalutamide, enzalutamide or abiraterone acetate were identified from administrative data (October 1, 2014-September 30, 2019). Adherence and persistence at six months postinitiation were used to evaluate patient factors and HRU. Results: Aged ≥75 years, Black race, chemotherapy use and higher pharmacy paid amounts were associated with poor adherence/persistence, which translated to higher HRU. Conclusions: Strategies to increase adherence and persistence may improve patient outcomes and associated HRU.

Lay abstract This study included 27,262 patients with advanced prostate cancer who started taking one of three oral cancer medications (apalutamide, enzalutamide or abiraterone acetate) between October 2014 and September 2019. Patients who were black, aged 75 years or older, who had chemotherapy or who had higher prescription costs had the most difficulty following dosing guidelines or staying on treatment. Patients who did not follow dosing guidelines required more healthcare services. In light of the extended survival and improved quality of life that oral cancer medication for advanced prostate cancer provides, helping patients to take the correct medication dose, at the right time, and for the recommended length of time may improve their outcomes and reduce medical costs.

Budget impact of lasmiditan for the acute treatment of migraine in the United States.

BACKGROUND: Three novel acute treatments for migraine-lasmiditan, ubrogepant, and rimegepant-were approved by the FDA in 2019 and 2020 for adults with migraine with and without aura. American Headache Society guidance recommends that these novel acute treatments be considered for patients who are contraindicated to or fail to respond or tolerate oral triptans, the current standard of acute care. OBJECTIVE: To estimate, from a US commercial plan perspective, the budget impact of adding lasmiditan as an option to a formulary that already includes ubrogepant and rimegepant. METHODS: Epidemiologic data were drawn from US Census data, the American Migraine Prevalence and Preventive study, and the first wave of the OVERCOME US survey, a web-based survey that included 21,000 patients with migraine. A model with a 3-year time horizon was built assuming that demand for the novel acute treatments would not vary based on whether lasmiditan is included in the formulary. The model examined a variety of populations, in particular beneficiaries with previous use of 1 or more oral triptans or contraindicated to triptans and beneficiaries with previous use of 2 or more oral triptans or contraindicated to triptans. Primary outcomes were the incremental differences in total cost and average cost per member per month (PMPM) between scenarios with and without lasmiditan. One-way sensitivity analyses with model parameters that were varied by plus or minus 15% were conducted to assess the effect of key parameters on the incremental total cost over 3 years. RESULTS: The addition of lasmiditan to a formulary that already includes ubrogepant and rimegepant resulted in a total savings of -$927,657 (-1.5% compared with the scenario without lasmiditan) over a 3-year time horizon in the population with previous history of using 1 or more oral triptans or contraindicated to a triptan. In the population with previous history of using 2 or more oral triptans or contraindicated, the addition of lasmiditan resulted in a total budget impact of -$466,518 (-1.3%) over a 3-year time horizon. Most of the cost savings was attributable to reductions in drug acquisition cost. Savings in total costs resulted in average incremental cost per PMPM of -0.03 and -$0.01, respectively. CONCLUSIONS: The addition of lasmiditan to the formulary as a novel acute treatment option for migraine alongside ubrogepant and rimegepant resulted in lower budget impact on a 3-year time horizon from a US commercial payer's perspective. This result is important to US commercial payers as they seek to incorporate the emerging novel acute treatments for migraine into their benefit designs.

Cost-effectiveness analysis of enzalutamide for patients with chemotherapy-naïve metastatic castration-resistant prostate cancer in Japan.

BACKGROUND: We aimed to evaluate cost-effectiveness of enzalutamide in chemotherapy-naïve metastatic castration-resistant prostate cancer patients in Japan. METHODS: A Markov model was developed to capture time spent by patients in various health states: stable, progression and death. Abiraterone acetate and docetaxel were set as active comparators. Clinical outcomes were obtained from the PREVAIL, COU-AA-302 and TAX327 trials. Treatment sequence, concomitant drugs and therapies for adverse events were estimated from responses to a survey by 14 Japanese prostate cancer experts. The analytic perspective was public healthcare payer, with a 10-year time horizon. The incremental cost-effectiveness ratio was estimated from quality-adjusted life-years and Japanese public healthcare costs. Probabilistic sensitivity analysis was performed to assess the robustness of the findings. RESULTS: According to the survey, the most common treatment sequences were (i) enzalutamide â†’ docetaxel â†’ cabazitaxel (enzalutamide-first sequencing), (ii) abiraterone â†’ enzalutamide â†’ docetaxel (abiraterone-first sequencing) and (iii) docetaxel→ enzalutamide â†’ cabazitaxel (docetaxel-first sequencing). In the base-case analysis, enzalutamide-first sequencing saved 1.74 million Japanese Yen versus abiraterone-first sequencing, with a 0.129 quality-adjusted life-year gain (dominant). Enzalutamide-first sequencing had a cost increase of 4.44 million Japanese Yen over docetaxel-first sequencing, with a 0.371 quality-adjusted life-years gain. The incremental cost-effectiveness ratio of enzalutamide-first sequencing versus docetaxel-first sequencing was estimated as 11.94 million Japanese Yen/quality-adjusted life-years. Probabilistic sensitivity analyses demonstrated that, compared with abiraterone-first sequencing, enzalutamide-first sequencing had an 87.4% probability of being dominant. CONCLUSIONS: Results modeled herein suggest that the enzalutamide-first sequencing is more cost-effective than the abiraterone-first sequencing, but less cost-effective than docetaxel-first sequencing for chemotherapy-naïve patients with metastatic castration-resistant prostate cancer.

Budget impact analysis of darolutamide for treatment of nonmetastatic castration-resistant prostate cancer.

BACKGROUND: Darolutamide, a structurally distinct androgen receptor inhibitor approved for the treatment of men with nonmetastatic castration-resistant prostate cancer (nmCRPC), has been shown to increase metastasis-free survival among men with nmCRPC compared with placebo. This treatment has a novel chemical structure that may also have safety, tolerability, and efficacy advantages for men with nmCRPC. OBJECTIVE: To estimate the projected budget impact of including darolutamide on a U.S. payer formulary as a treatment option for men with nmCRPC. METHODS: A budget impact model was developed to evaluate darolutamide for nmCRPC for a hypothetical 1-million-member plan over a 5-year period. Costs (drug acquisition, drug administration, and treatment-related adverse events [AEs]) were estimated for 2 scenarios: with and without darolutamide treatment for nmCRPC. The budget impact of darolutamide was calculated as the difference in costs for these 2 scenarios. An analysis for high-risk nmCRPC also was conducted. The model included treatments recommended by the National Comprehensive Cancer Network (e.g., apalutamide and enzalutamide) and potential comparators that are used but are not specifically indicated for nmCRPC. All treatments were assumed to be administered in combination with a weighted average androgen deprivation therapy comparator (consisting of luteinizing hormone-releasing hormone [LHRH] agonists, LHRH antagonists, and first-generation antiandrogens). Market share estimates were derived from interviews with physicians treating men with nmCRPC. The model includes grade 3-4 AEs, and the rates were obtained from clinical trial data. Costs were taken from publicly available sources and varied in a one-way sensitivity analysis. RESULTS: For a plan with 1 million lives, there were approximately 90 incident cases of nmCRPC (46 high risk) each year, with 332 (109 high risk) treatment-eligible cases by year 5. Darolutamide's market share increased from 3.6% in year 1 to 18% in year 5. Given the utilization of other agents, introducing darolutamide along with other targeted therapies was predicted to increase the total budget by $158,640 ($0.0132 per member per month [PMPM]) in year 1, which decreased over time to a cost savings of $149,240 ($0.0124 PMPM) by year 5. The scenario with darolutamide showed reduced AE costs each year. Similar results were observed for the high-risk nmCRPC population. CONCLUSIONS: Adding darolutamide to a U.S. payer formulary for the treatment of nmCRPC can result in a manageable increase in the budget that is partly offset by AE costs in the first 4 years, followed by a cost savings by year 5.

Adherence and out-of-pocket costs among Medicare beneficiaries who are prescribed oral targeted therapies for advanced prostate cancer.

BACKGROUND: Abiraterone and enzalutamide are high-cost oral therapies that increasingly are used to treat patients with advanced prostate cancer; these agents carry the potential for significant financial consequences to patients. In the current study, the authors investigated coping and material measures of the financial hardship of these therapies among patients with Medicare Part D coverage. METHODS: The authors performed a retrospective cohort study on a 20% sample of Medicare Part D enrollees who underwent treatment with abiraterone or enzalutamide between July 2013 and June 2015. The authors described the variability in adherence rates and out-of-pocket payments among hospital referral regions in the first 6 months of therapy and determined whether adherence and out-of-pocket payments were associated with patient factors and the socioeconomic characteristics of where a patient was treated. RESULTS: There were 4153 patients who filled abiraterone or enzalutamide prescriptions through Medicare Part D in 228 hospital referral regions. The mean adherence rate was 75%. The median monthly out-of-pocket payment for abiraterone and enzalutamide was $706 (range, $0-$3505). After multilevel, multivariable adjustment for patient and regional factors, adherence was found to be lower in patients who were older (69% for patients aged ≥85 years vs 76% for patients aged <70 years; P < .01) and in those with low-income subsidies (69% in those with a subsidy vs 76% in those without a subsidy; P < .01). Both Hispanic ethnicity and living in a hospital referral region with a higher percentage of Hispanic beneficiaries were found to be independently associated with higher out-of-pocket payments for abiraterone and enzalutamide. CONCLUSIONS: There were substantial variations in the adherence rate and out-of-pocket payments among Medicare Part D beneficiaries who were prescribed abiraterone and enzalutamide. Sociodemographic patient and regional factors were found to be associated with both adherence and out-of-pocket payments.

Budget impact analysis of betrixaban for venous thromboembolism prophylaxis in nonsurgical patients with acute medical illness in the United Kingdom.

OBJECTIVES: Venous thromboembolism (VTE) incurs substantial costs to the UK National Health Service (NHS). Betrixaban is approved in the US for VTE prophylaxis with a recommended 35-42 days of treatment. This analysis modeled the budget impact of introducing betrixaban for extended-duration VTE prophylaxis in nonsurgical patients with acute medical illness at risk of VTE in the UK, where it is not yet licensed. METHODS: The 5-year budget impact of introducing betrixaban into current prophylaxis (low molecular weight heparin and fondaparinux) was estimated for the UK NHS. The Phase 3 APEX study provided primary event (VTE, myocardial infarction, ischemic stroke, and death; all-cause or VTE-related) and treatment complications data. Literature informed risk of recurrent events and long-term complications, population, market share, and costs for treatment and management of events. Network meta-analyses informed symptomatic DVT, pulmonary embolism and VTE-related death rates in fondaparinux patients. Deterministic sensitivity analyses explored uncertainty. RESULTS: Introducing betrixaban accrued savings of £1,290,000-£23,000,000 in years 1-5. Savings were from reduced primary VTE events, which reduced recurrent events and future complications. All sensitivity analyses showed savings. CONCLUSION: Introducing extended-duration VTE prophylaxis with betrixaban in the UK would accrue substantial savings annually over the next 5 years compared to current prophylaxis. Clinical trial registration: www.clinicaltrials.gov identifier is NCT01583218.

Momelotinib for the treatment of myelofibrosis.

Introduction: The abnormally activated JAK-STAT pathway plays a central role in the pathogenesis of BCR/ABL-negative myeloproliferative neoplasms (MPNs), simultaneously providing a theoretical and clinical basis for the development of small-molecule compounds targeting JAK. The first approved drug, ruxolitinib, demonstrated a rapid and durable improvement of symptoms and splenomegaly accompanied with better overall survival in myelofibrosis (MF) patients. However, ruxolitinib-related adverse effects and resistance are limitations, so there is an urgent need to develop new JAK inhibitors to retain the efficacy of ruxolitinib and avoid its deficiency. Areas covered: This review discusses the preclinical and clinical studies of momelotinib (MMB) aiming to gain a deeper understanding of the advantages and clinical limitations of this drug. Expert opinion: The clinical trial data available thus far indicate that MMB is not inferior to ruxolitinib in spleen response and symptoms response, with the improvement of anemia surprising. The only obstacle that may slowdown its approval is treatment-emerged peripheral neuropathy (PN). If we can minimize MMB's treatment-related PN by administration optimization, MMB promises to be a good choice of individualized treatment for MF patients mainly manifesting as anemia.

Phase I/II Clinical Trial-Based Early Economic Evaluation of Acalabrutinib for Relapsed Chronic Lymphocytic Leukaemia.

OBJECTIVES: The objective of this study was to construct an early economic evaluation for acalabrutinib for relapsed chronic lymphocytic leukaemia (CLL) to assist early reimbursement decision making. Scenarios were assessed to find the relative impact of critical parameters on incremental costs and quality-adjusted life-years (QALYs). METHODS: A partitioned survival model was constructed comparing acalabrutinib and ibrutinib from a UK national health service perspective. This model included states for progression-free survival (PFS), post-progression survival (PPS) and death. PFS and overall survival (OS) were parametrically extrapolated from ibrutinib publications and a preliminary hazard ratio based on phase I/II data was applied for acalabrutinib. Deterministic and probabilistic sensitivity analyses were performed, and 1296 scenarios were assessed. RESULTS: The base-case incremental cost-effectiveness ratio (ICER) was £61,941/QALY, with 3.44 incremental QALYs and incremental costs of £213,339. Deterministic sensitivity analysis indicated that survival estimates, utilities and treatment costs of ibrutinib and acalabrutinib and resource use during PFS have the greatest influence on the ICER. Probabilistic results under different development scenarios indicated that greater efficacy of acalabrutinib would decrease the likelihood of cost effectiveness (from 63% at no effect to 2% at maximum efficacy). Scenario analyses showed that a reduction in PFS did not lead to great QALY differences (- 8 to - 14% incremental QALYs) although it did greatly affect costs (- 47 to - 122% incremental pounds). For OS, the opposite was true (- 89 to - 93% QALYs and - 7 to - 39% pounds). CONCLUSIONS: Acalabrutinib is not likely to be cost effective compared with ibrutinib under current development scenarios. The conflicting effects of OS, PFS, drug costs and utility during PFS show that determining the cost effectiveness of acalabrutinib without insight into all parameters complicates health technology assessment decision making. Early assessment of the cost effectiveness of new products can support development choices and reimbursement processes through effective early dialogues between stakeholders.

Cost-Effectiveness of Betrixaban Compared with Enoxaparin for Venous Thromboembolism Prophylaxis in Nonsurgical Patients with Acute Medical Illness in the United States.

BACKGROUND: Studies show that the risk of venous thromboembolism (VTE) continues post-discharge in nonsurgical patients with acute medical illness. Betrixaban is the first anticoagulant approved in the United States (US) for VTE prophylaxis extending beyond hospitalization. OBJECTIVE: The aim was to establish whether betrixaban for VTE prophylaxis in nonsurgical patients with acute medical illness at risk of VTE in the US is cost-effective compared with enoxaparin. METHODS: A cost-effectiveness analysis was conducted, estimating the cost per quality-adjusted life-year (QALY) gained with betrixaban (35-42 days) compared with enoxaparin (6-14 days) from a US payer perspective over a lifetime horizon. A decision tree (DT) estimated primary VTE events, thrombotic events, and treatment complications in the first 3 months based on data from the phase III Acute Medically Ill VTE Prevention with Extended Duration Betrixaban study. A Markov model estimated recurrent events and long-term complication risks from published literature. EuroQoL-5 Dimensions utility data and costs inflated to 2017 US dollars (US$) were from published literature. Results were discounted at 3.0% per annum. Deterministic and probabilistic sensitivity analyses explored uncertainty. RESULTS: Betrixaban dominated enoxaparin, with savings of US$784 and increased QALYs of 0.017 per patient. In addition, betrixaban dominated enoxaparin across all sensitivity analyses, but was most sensitive to utilities and DT probabilities. Furthermore, probabilistic sensitivity analysis found that betrixaban was more cost-effective than enoxaparin at all willingness-to-pay thresholds. CONCLUSION: Betrixaban can be considered cost-effective for nonsurgical patients with acute medical illness at risk of VTE, requiring longer VTE prophylaxis from hospitalization through post-discharge.

Cost-effectiveness of roflumilast as an add-on to triple inhaled therapy vs triple inhaled therapy in patients with severe and very severe COPD associated with chronic bronchitis in the UK.

Purpose: Patients with severe COPD are at high risk of experiencing disease exacerbations, which require additional treatment and are associated with elevated mortality and increased risk of future exacerbations. Some patients continue to experience exacerbations despite receiving triple inhaled therapy (ICS plus LAMA plus LABA). Roflumilast is recommended by the Global Initiative for Chronic Obstructive Lung Disease as add-on treatment to triple inhaled therapy for these patients. This cost-effectiveness analysis compared costs and quality-adjusted life-years for roflumilast plus triple inhaled therapy vs triple inhaled therapy alone, using data from the REACT and RE2SPOND trials. Patients and methods: Patients included in the analysis had severe to very severe COPD, FEV1 <50% predicted, symptoms of chronic bronchitis and ≥2 exacerbations per year. Our model was adapted from a previously published and validated model, and the analyses conducted from a UK National Health Service perspective. A scenario analysis considered a subset of patients who had experienced at least one COPD-related hospitalization within the previous year. Results: Roflumilast as add-on to triple inhaled therapy was associated with non-significant reductions in rates of both moderate and severe exacerbations compared with triple inhaled therapy alone. The incremental cost-effectiveness ratio (ICER) for roflumilast as add-on to triple inhaled therapy was £24,976. In patients who had experienced previous hospitalization, roflumilast was associated with a non-significant reduction in the rate of moderate exacerbations, and a statistically significant reduction in the rate of severe exacerbations. The ICER for roflumilast in this population was £7,087. Conclusions: Roflumilast is a cost-effective treatment option for patients with severe or very severe COPD, chronic bronchitis, and a history of exacerbations. The availability of roflumilast as add-on treatment addresses an important unmet need in this patient population.

A longitudinal, retrospective cohort study on the impact of roflumilast on exacerbations and economic burden among chronic obstructive pulmonary disease patients in the real world.

BACKGROUND: Roflumilast is approved in the United States to reduce the risk of COPD exacerbations in patients with severe COPD. Exacerbation rates, health care resource utilization (HCRU), and costs were compared between roflumilast patients and those receiving other COPD maintenance drugs. METHODS: LifeLink™ Health Plan Claims Database was used to identify patients diagnosed with COPD who initiated roflumilast (roflumilast group) or ≥3 other COPD maintenance drugs (non-roflumilast group) from May 1, 2011 to December 31, 2012. Patients must have been enrolled for 12 months before (baseline) and 3 months after (postindex) the initiation date, ≥40 years old, not systemic corticosteroid dependent, and without asthma diagnosis at baseline. Difference-in-difference models compared change from baseline in exacerbations, HCRU (office, emergency visits, and hospitalizations), and total costs between groups, adjusting for baseline differences. RESULTS: A total of 14,211 patients (roflumilast, n=710; non-roflumilast, n=13,501) were included. During follow-up, the rate of overall exacerbations per patient per month decreased by 11.1% in the roflumilast group and increased by 15.9% in the non-roflumilast group (P<0.001). After controlling for baseline differences, roflumilast-treated patients experienced a greater reduction in exacerbations (0.0160 fewer exacerbations per month, P=0.01), numerically greater reductions in hospital admissions (0.003 fewer per month, P=0.57), office visits (0.46 fewer per month, P=0.26), and total costs from baseline compared with non-roflumilast patients ($116 less per month, P=0.62). CONCLUSION: In a real-world setting, patients initiating roflumilast experienced reductions in exacerbations versus patients treated with other COPD medications.

Roflumilast: Who Is Using It and How It Affects Health Care Resource Utilization and Costs.

OBJECTIVE: Compare baseline characteristics, health care resource utilization (HCRU), and associated costs of COPD patients treated with add-on roflumilast with those of other combination medications. DESIGN: Retrospective cohort study. METHODOLOGY: Patients aged 40 years with a diagnosis of chronic obstructive pulmonary disease (COPD) between March 1, 2011, and Nov. 30, 2012, were identified from the HealthCore Integrated Research Database and classified as roflumilast or nonroflumilast combination-therapy cohorts. Baseline characteristics were compared for all patients. HCRU and costs were compared between matched (M) roflumilast and nonroflumilast cohorts, using propensity score as a partial balancing score and then complementing the score with exact matching on specifically important variables. Generalized linear model and Poisson regression were used to estimate the adjusted differences in total costs and hospitalization rates, respectively, between the 2 matched cohorts. RESULTS: A total of 695 roflumilast and 30,542 nonroflumilast combination therapy users were identified. At baseline, the roflumilast cohort had more complex COPD and a higher number of severe and moderate COPD exacerbations relative to the nonroflumilast cohort. After matching, the roflumilast (M) and nonroflumilast (M) cohorts (n = 328 in each) had similar mean age, gender distribution, and follow-up time. The roflumilast (M) cohort had significantly higher pharmacy-related, per-patient, per-month (PPPM) costs (P < .001) and similar total cost (P = .90). After adjusting for confounding variables, no difference was observed between the 2 cohorts in total costs (P = .86) and number of hospitalizations (P = .65). CONCLUSION: Findings suggest that patients in the roflumilast cohort, relative to the nonroflumilast cohort, were more severely ill in the real-world setting. Despite higher pharmacy costs, the total cost for the roflumilast cohort was statistically similar to the nonroflumilast cohort. Future studies with longer follow-up are needed to evaluate the long-term economic impact of roflumilast use.

Impact of roflumilast on exacerbations of COPD, health care utilization, and costs in a predominantly elderly Medicare Advantage population.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) exacerbations are associated with declining lung function and health-related quality of life, and increased hospitalization and mortality. Clinical trials often poorly represent the elderly and thus have only partial applicability to their clinical care. OBJECTIVE: To compare exacerbations, COPD-related health care utilization (HCU), and costs in a predominantly elderly Medicare COPD population initiated on roflumilast versus those not initiated on roflumilast. METHODS: Deidentified administrative claims data from a large, national payer were utilized. Medicare patients aged 40-89 years with at least one COPD diagnosis from May 1, 2010 to December 31, 2012 were included. Members with at least one roflumilast pharmacy claim (index) were assigned to the roflumilast group and those without were assigned to the non-roflumilast group. Proxy index dates for the non-roflumilast group were randomly assigned for similar distribution of all patients' time at risk. Subjects with at least one pre-index COPD exacerbation had to be continuously enrolled for ≥365 days pre-index and post-index. Unadjusted and adjusted difference-in-difference (DID) analyses contrasted pre-index with post-index changes in exacerbations, HCU, and costs of roflumilast treatment compared with non-roflumilast treatment. RESULTS: A total of 500 roflumilast and 60,145 non-roflumilast patients were included (mean age 69.7 and 72.3 years, respectively; P<0.0001). Unadjusted DID favored roflumilast for all exacerbations, with greater pre-index to post-index reductions in mean per 30-day COPD-related hospitalizations (-0.0182 versus -0.0013, P=0.009), outpatient visits (-0.2500 versus -0.0606, P<0.0001), and COPD-related inpatient costs (-US$141 versus -US$11, P=0.0346) and outpatient costs (-US$31 versus -US$4, P<0.0001). Multivariate analyses identified significantly improved pre-index to post-index COPD-related total costs (P=0.0005) and total exacerbations (P<0.0001) for the roflumilast group versus non-roflumilast group. CONCLUSION: In a predominantly elderly Medicare COPD population, newly initiated roflumilast patients displayed similar or significantly better unadjusted reductions in all exacerbation-related, COPD-related HCU-related, and COPD-related costs outcomes compared with non-roflumilast patients. These analyses also suggest better adjusted COPD-related costs and total exacerbations for roflumilast-initiated patients.

[Induction of hospital indebtedness due to medicine purchases under monopoly conditions: the case of imatinib mesylate]. / Indução de endividamento hospitalar na compra de medicamento em situação de monopólio: o caso do mesilato de imatinibe.

Medicine expenditures consume a large share of the health budget, so knowledge on the use of these funds is essential for decision-making in public health and improvement of pharmaceutical care. This study analyzed the indebtedness of a high-complexity university hospital due to increased spending on imatinib mesylate. The descriptive study was based on analysis of documents and records in the Hospital Information System (SIH) from 2002 to 2010. Starting with inclusion of the medicine in the budget, the study mapped strategies by the pharmaceutical industry and government, as well as government responses to reduce the product's price. The systematization and publication of information stored in files and electronic databases can help monitor the results of programs funded by the Brazilian Ministry of Health.

Changing the cost of care for chronic myeloid leukemia: the availability of generic imatinib in the USA and the EU.

Imatinib is an oral tyrosine kinase inhibitor and considered to be the most successful targeted anti-cancer agent yet developed given its substantial efficacy in treating chronic myeloid leukemia (CML) and other malignant diseases. In the USA and the European Union (EU), Novartis' composition of matter patent on imatinib will expire in 2016. The potential impact on health system spending levels for CML after generic imatinib becomes available is the subject of significant interest among stakeholders. The extent of the potential savings largely depends on whether and to what extent prices decline and use stays the same or even increases. These are also empirical questions since the likely spending implications following generic imatinib's availability are predicated on multiple factors: physicians' willingness to prescribe generic imatinib, molecule characteristics, and health system priorities. This article discusses each of these issues in turn. We then review their implications for the development of country-specific cost-effectiveness models to predict the implications for cost and quality of care from generic imatinib.
