Trial-based cost-effectiveness of abatacept for rheumatoid arthritis patients in Italy.

INTRODUCTION: Rheumatoid arthritis (RA) is a chronic, inflammatory disorder leading to disability and reduced quality of life. Effective treatment is a significant economic burden on the Italian healthcare system. Economic models in RA are commonly based on indirect treatment comparisons. METHODS: This study assessed the cost-effectiveness of abatacept relative to adalimumab for RA in Italy based on a head-to-head trial by means of a cost-consequence analysis. RESULTS: Health benefits based on the most stringent efficacy criteria were in favor of abatacept compared to adalimumab. Rates for more costly adverse events were higher for adalimumab compared to abatacept, which was reflected in the lower costs for abatacept (-€237,246 or -€237per patient). CONCLUSION: The health economic value of abatacept compared with adalimumab from the perspective of the Italian NHS depends on the choice of health outcome. Health gains with abatacept were generally based on more stringent criteria and lower total costs.

Pharmacoeconomic evaluation of tiotropium bromide in the long-term treatment of chronic obstructive pulmonary disease (COPD) in Italy.

The randomized, double-blind trial UPLIFT(®) demonstrated in 5,993 patients with moderate to very severe COPD that 4 years of tiotropium bromide therapy were associated with improvements in lung function, exacerbations, quality of life, and mortality compared with placebo. The pharmacoeconomic evaluation was performed through a probabilistic, patient-level simulation Markov model. Routine COPD care (RC) was compared with the inclusion of tiotropium bromide on it. The analysis was conducted over a lifetime horizon, with 1 year cycles and a 3.5% annual discount rate. Patients were characterized by gender, age, height, smoking status, and forced expiratory volume in 1 s (FEV1). FEV1 time trend was modeled according to the annual decline recorded in UPLIFT®. Mortality derived from that of the general Italian population was adjusted by smoking status and FEV1. Health utilities derived from published Italian observational studies and were varied in time according to UPLIFT® data. Exacerbation rates were derived from a published Italian observational prospective study. The cost perspective was that of the Italian National Health Service. Healthcare resource consumption for RC and exacerbations derived from Italian observational studies were valued according to current price and tariffs. Simulated patients in the tiotropium arm gained an average (95% CI) 0.50 (-1.63 to 6.27) Life Years (LYs) and 0.42 (-0.25 to 3.05) Quality-Adjusted Life Years (QALYs). The incremental lifetime cost resulted €3,357 (-€10,669 to €29,820). The incremental cost-effectiveness ratio (ICER) was €6,698/LY and €7,916/QALY. In the cost-effectiveness acceptability curve (CEAC), tiotropium had a 90% probability of being cost-effective for a willingness to pay (WTP) threshold of € 10,000/QALY.

Pharmacoeconomic evaluation of the MF59--adjuvanted influenza vaccine in the elderly population in Italy.

INTRODUCTION: Influenza vaccination has proven effective in the reduction of influenza-like illness (ILI) cases and influenza-related hospitalizations, drug consumption, primary care consultations and deaths in the elderly population. The aim of this study is the assessment of the financial budget impact of a seasonal vaccination program based on the use of the MF59 adjuvanted vaccine as compared with the traditional vaccine or the absence of vaccination in Italian elderly population. METHODS: A pharmacoeconomic simulation model was developed to simulate the effect of the three different vaccination programs during a single influenza season. Health economics and demographic data were taken from specific Italian sources, and vaccine effectiveness data derived from published literature. Direct medical costs were considered according to current Italian prices and tariffs. RESULTS: About 83% of the 12 million people of at least 65 years of age currently resident in Italy can be considered at high risk for influenza complications due to underlying chronic diseases. Absence of vaccination could lead to more than 2 million ILl cases, and 29,000 related deaths. The vaccination program with a coverage rate of 65.6% would lead to an estimated 1.5 million ILl cases (26.9% reduction) with a standard vaccine and to 1.3 million (35.8% reduction) with the MF59 adjuvanted vaccine with a relative increase of avoided cases of 33,1%. The standard vaccination program produced a moderate direct cost increase of about 50 million Euro (+4.6%), whereas the adjuvanted vaccine provided an estimated saving of about 74 million Euro (-6.8%), both compared to the non vaccination. Cost savings were mainly related to hospital admissions avoided in the elderly population (>or=65 years of age). CONCLUSIONS: The vaccination with the MF59 adjuvanted vaccine resulted more effective and cost saving when compared with the standard vaccination and with no vaccination, thus representing the optimal strategy for the elderly population. The standard vaccine, even though a light cost increase, still proved to be effective compared to the null option, with the initial cost for the vaccination program nearly offset by healthcare resources savings obtained during the season.

Cost-utility of add-on omalizumab in difficult-to-treat allergic asthma in Italy.

OBJECTIVE: Omalizumab (OM), an innovative biological treatment for difficult asthma with perennial sensitisations, is an humanized monoclonal anti-IgE antibody that binds free circulating IgE; inhibits mast cell and basophil activation by combining free IgE, leads to IgE receptor down-regulation, thus blocking the inflammatory cascade. AIM OF THE STUDY: To assess real-world cost-utility ofadd-on OM in Italy. METHODS: changes in clinical and economical outcomes, and in quality of life (QoL) associated with add-on OM in adults (n=23) with severe dfficult asthma were compared with those recorded before OM in the same subjects. Variables were: lung function; IgE levels; health status; ACT score; QoL (SGRQ); n. GP and specialist visits; emergency visits; hospitalizations, and concomitant pharmacological treatments. Further indices were: changes in Health-related QoL; total health-care costs, and incremental cost/utility. Data were statistically compared (Student's T test), and p < 0.01 was accepted for statistical significance. RESULTS: asthma clinical outcomes and patients' health-related quality of life improved significantly by adding OM, and both costs for drugs and hospital care dropped significantly (p < 0.01). The net economic effect was a 350 Euro increase in overall monthly costs; when related to health benefits, it corresponded to an incremental cost/utility ratio ofabout 26,000 Euro/QALY, which represents a quite favourable figure in terms of willingness to pay for health benefits in industrialised countries. CONCLUSIONS: Omalizumab added to an optimised therapy significantly improves clinical outcomes in difficult-to-treat, persistent allergic asthma. Costs also increased, but proved justified by health benefits achieved.

Cost-effectiveness analysis of LHRH agonists in the treatment of metastatic prostate cancer in Italy.

OBJECTIVES: Luteinizing hormone-releasing hormone (LHRH) agonists represent one of the main cost factors in the management of patients with metastatic prostate cancer. We compared the cost-effectiveness of the five different 3-month formulations of LHRH agonists currently available for advanced prostate cancer in Italy, because these differ both in their capacity to suppress testosterone and in their acquisition costs. METHODS: A probabilistic, patient-level simulation model was developed to compare the cost-effectiveness, from the perspective of the Italian National Health Service (INHS), of leuprorelin 11.25 mg and 22.5 mg, triptorelin 11.25 mg, buserelin 9.9 mg, and goserelin 10.8 mg. The model incorporated testosterone-dependent progression-free and cancer-specific survival functions, LHRH agonist effectiveness data, and national costs and tariffs. Cox's proportional hazard models were used to compute total and progression-free survival functions based on clinical data from 129 patients with metastatic prostate cancer treated in an Italian center. Bayesian random effects models were employed to summarize evidence from published literature on testosterone suppression obtained with the available LHRH agonists. RESULTS: Estimated total survival was ≈5 years, with a maximum difference between treatment options of ≈2 months. There was a mean difference of almost €2,500 in lifetime total costs between the least costly option (leuprorelin 22.5 mg) and the most expensive (goserelin). In the incremental cost-effectiveness analysis, leuprorelin 22.5 mg dominated all alternatives except buserelin, which had an incremental cost-effectiveness ratio versus leuprorelin 22.5 mg of ≈€12,000 per life-month gained. CONCLUSIONS: Based on modelling with meta-analysis of comparative survival data, leuprorelin 22.5 mg was the most cost-effective treatment of the available depot formulation LHRH agonists.

Rituximab in the treatment of rheumatoid arthritis patients in Italy: a budget impact analysis.

OBJECTIVES: The objective of this Budget Impact Analysis is to evaluate the financial implications of a rituximab-based sequencing strategy in the treatment of rheumatoid arthritis in the perspective of the Italian National Health Service. METHODS: Yearly patients who were eligible for a second-line biological DMARD in Italy were entered into a 5-year model. A Markov chain reproduced the course of this cohort under a number of alternative strategies, including anti-TNF-α cycling and rituximab or abatacept as second and third line agents. The dynamic of the simulation was given by first biological drug failure data, mortality rates, and survival-on-treatment data from published literature. Drug acquisition, administration and monitoring costs were assessed. RESULTS: Italian patients refractory to a first anti-TNF-α therapy resulted to be about 650 per year, giving a cumulative number of treated patients in five years of 3,240. The anti-TNF-α cycling had a total direct cost which rose from €8.2 million in the first year to €33.8 million in the fifth. The cost per patient of rituximab was lower than the average cost of the anti-TNF-α therapies; the annual difference was around € 4,300. The savings gained from lower individual costs with rituximab were partially offset by the increasing number of patients receiving active medication, resulting in a substantial cost equivalence between third line rituximab and anti-TNF-α cycling scenarios; rituximab, as a second line therapy, produced a savings in total costs of -31.8%. Strategies including abatacept shared the same dynamics, but with higher costs. CONCLUSIONS: The introduction of rituximab in clinical practice could allow an increase in the number of patients receiving an active rheumatoid arthritis treatment without inflating therapy costs.

Economic evaluation of treatment with orlistat in Italian obese patients.

UNLABELLED: The XENDOS study showed that behavioural and pharmacological therapy can decrease the risk of metabolic disorders in obese patients. METHODS: A probabilistic Bayesian Markov model simulating the outcomes of orlistat treatment on the obese Italian population has been developed with the WinBUGS software. The model integrates an algorithm to estimate cardiovascular risk based on Framingham Heart Study equations. Analyses adopted the societal cost perspective, including direct medical costs borne by both the National Health Service and the patient, since orlistat is not included in the Italian reimbursement list. RESULTS: The simulation on the Italian obese population estimated an average increase in quality-adjusted life expectancy, a reduction of cardiovascular events and new diabetes cases. The average incremental cost-utility ratio is euro75.3 (7.6-180.6) x 1000/QALY. The subgroup analysis showed that the benefits are relatively greater in older patients and in patients with impaired glucose tolerance (IGT). Two hypotheses have been explored to estimate the impact of a potential reimbursement decision by the Italian NHS: (1) orlistat is given to every obese patient; (2) orlistat is given only to obese IGT patients with a previous glucose tolerance general screening program to assess their eligibility. The cost utility of the strategies are euro42.3 (-22.16-108.7) and euro10.16 (-60.4-38.76) x 1000/QALY, respectively. CONCLUSION: Orlistat shows a good pharmacoeconomic profile and, in particular, the strategy of a screening programme to identify and treat the IGT subgroup has a cost-utility value of about euro10000/QALY. This value is lower than that of several therapeutic strategies commonly accepted and reimbursed in developed countries.

Cost-effectiveness and healthcare budget impact in Italy of inhaled corticosteroids and bronchodilators for severe and very severe COPD patients.

Current practice guidelines for the treatment of COPD recommend the use of combined inhaled corticosteroids and long-acting bronchodilators in severe and very severe patients (GOLD stages III and IV). The aim of this study was to evaluate, through a simulation model, the economic consequences of this recommendation in Italy. We developed a cost-effectiveness analysis (CEA) on five alternative therapeutic strategies (salmeterol/fluticasone, SF; formoterol! budesonide, FB; salmeterol alone, S; fluticasone alone, F; control, C). Published data on the Italian COPD population and efficacy data from international reference trials were fitted in a disease progression model based on a Markov chain representing severity stages and death. The yearly total direct costs of treating COPD patients in Italy was estimated at approximately Euro 7 billion, with a mean cost per patient per year of around Euro 2450. Mean survival of the cohort is 11.5 years. The C and F strategies were dominated (ie, are associated with worse outcomes and higher costs) by all alternatives. SF and FB were the most effective strategies, with a slight clinical superiority of SF, but they were also marginally more expensive than S. Incremental cost-effectiveness of SF vs S was Euro 679.5 per avoided exacerbation and Euro 3.3 per symptom-free day. Compared with current practice, the recommended use of combined inhaled corticosteroids and long-acting bronchodilators for severe and very severe COPD patients has the potential for improving clinical outcomes without increasing healthcare costs.

[Osteoporosis: problems and considerations of economical nature]. / Osteoporosi: problematiche e considerazioni di carattere economico.

In 1991 WHO classified osteoporosis as a major social disease, on the basis of its high prevalence, expected to rise in the future, its physical and psychological consequences and its economical costs for both the society and the individual. In the past, costs, especially the undirected and intangible ones, have been largely underestimated, due to their complex quantification. A more accurate and a deeper evaluation of the pathology and its economical burden on National Health Services will lead to a better planning of prevention strategies.
