[Cost-effectiveness analysis of delayed-release dimethyl-fumarate in the treatment of relapsing-remitting multiple sclerosis in Italy]
Full text linkINTRODUCTION: Disease Modifying Therapies (DMTs) have significantly improved clinical conditions of Relapsing Remitting Multiple Sclerosis (RRMS) patients. However, several unmet needs are still relevant in RRMS. Recently, a new therapy, delayed-release dimethyl-fumarate (DMF; also known as gastro-resistant DMF), has been approved and reimbursed by the Italian Drug Agency (AIFA) for the treatment of RRMS.OBJECTIVE: To compare the cost-effectiveness of DMF vs. pharmacological alternatives indicated for the first-line treatment of RRMS in Italy.METHODS: The analysis was conducted from the perspective of the Italian National Healthcare Service (NHS) and outcomes and costs were evaluated over a 50-year time horizon (equivalent to a lifetime horizon). Both outcomes and costs were discounted at 3.5%. The Markov model estimates the clinical and economic consequences of treating RRMS patients with the following therapeutic options: DMF, interferon (IFN) beta-1a intramuscular (IM); IFN beta-1a subcutaneous (SC) at two different doses, 22 mcg and 44 mcg; IFN beta-1b SC; glatiramer acetate (GA) SC 20 mg; oral teriflunomide. Clinical efficacy data used in this analysis came from an elaboration of the mixed treatment comparison (MTC) already published. According to the Italian NHS perspective, only the following direct costs were considered: pharmacological treatment acquisition, treatment monitoring, relapse management, direct costs associated with disability, adverse event management. Administration costs were assumed equal to €0, because every treatment included in the economic analysis can be self-administered. One-way and probabilistic sensitivity analyses were developed and cost effectiveness acceptability curves generated.RESULTS: In the base-case analysis, DMF was more efficacious than alternatives, in terms of both survival (19.496 vs. 19.297-19.461 discounted LYs, respectively), and QALYs (6.548 vs. 5.172- 6.212 discounted QALYs, respectively). Per-patient lifetime costs with DMF amounted to € 276,500, similarly to the other options. DMF was the drug with the largest effect of disability cost reduction. DMF was dominant vs. IFN beta-1a 44 mcg and cost-effective vs. all other IFNs, GA and teriflunomide, with incremental cost-effectiveness ratio (ICERs) between € 11,272 and € 23,409. All ICER values were lower than the € 50,000 per QALY threshold. One-way sensitivity analysis showed that, for all tested scenarios, ICER of DMF vs. therapeutic alternatives remained favourable (≤ 50.000 €/QALY gained) and the results of probabilistic sensitivity analysis showed that the probability for DMF of being favourable (≤ 50.000 €/QALY gained) was between around 70% and 93%, thus ensuring robustness of the results.CONCLUSIONS: The results of this economic analysis show that, at the current price and the described assumptions, DMF represents a cost-effective option vs. other available first-line treatments indicated in RRMS in the perspective of the Italian NHS.[Article in Italian

[Budget impact analysis for peginterferon beta-1a in relapsing remitting multiple sclerosis in Italy]
Full text link BACKGROUND: Peginterferon beta-1a, injected every two weeks, is the first approved pegylated interferon beta-1a for the treatment of relapsing remitting multiple sclerosis (RRMS). The objective of this analysis was to estimate the economic impact due to the introduction of peginterferon beta-1a in Italy.METHODS: This analysis was conducted with a three-year time horizon with the support of a simple decision-analytic model adopting the perspective of the Italian National Healthcare Service (NHS). Healthcare costs sustained by the Italian NHS to manage the RRMS population (drug treatment, monitoring, relapse management, adverse events management) were calculated over 3 years and compared in two scenarios: the base scenario where interferons-beta and glatiramer acetate (GA) are used to treat RRMS patients, and an alternative scenario where peginterferon beta-1a can also be used to treat RRMS patients. The target population was approximately 35,500, 37,500 and 39,500 patients at year 1, 2 and 3 respectively, based on the published literature and market data. The efficacy of treatments was simulated as a reduction of relapse rates and was derived from a Network Meta-analysis. Unit costs were based on current prices and tariffs, and the published literature. A one-way sensitivity analysis was developed.RESULTS: According to current price and described assumptions, it was estimated that the introduction of peginterferon beta-1a would result in a decrease of total costs when compared with the base scenario. The cost in the base scenario was estimated to be € 321.5, € 339.7 and € 357.8 million in years 1, 2, and 3, respectively. In the alternative scenario, the same costs resulted in about € 321.1, € 338.6 and € 356.2 million, respectively. The cumulative budget impact over three years period was approximately a cost saving of € 3.1 million (about 0.3% saving).CONCLUSION: The adoption of peginterferon beta-1a for the treatment of RRMS would be viewed as economically sustainable by the Italian NHS.[Article in Italian
Budget impact analysis of apixaban to treat and prevent venous thromboembolism in Italy
Full text linkBACKGROUND: Venous thromboembolism (VTE), a collective term for deep vein thrombosis (DVT) and pulmonary embolism (PE), is a serious vascular condition associated to high economic and clinical burden. Apixaban, a Novel Oral Anticoagulant (NOAC) has shown non-inferiority efficacy versus the current standard of care (low molecular weight heparin [LMWH]/vitamin K antagonist [VKA]) in the acute treatment and prevention of VTE and a significant reduction in the risk of bleeding.AIM: Evaluate the economic impact of the use of apixaban for treatment and prevention of DVT and PE from the perspective of the Italian National Health System (NHS).METHODS: A budget impact model was adapted in order to compare clinical outcomes and economic consequences associated to apixaban vs. LMWH/VKA and others NOACs over a three-year time horizon in the Italian setting. In the analysis two scenario were compared: status quo scenario without apixaban and an alternative scenario with apixaban. Only direct healthcare costs have been considered.RESULTS: Assuming a population of patients receiving apixaban over the first 3 years equal to 20,957, the introduction of apixaban is associated to an incremental saving of € 821,748 in the first years, € 1,250,454 in the second year, and € 1,866,466 in the third year. The total net saving over the 3-year period is € 3,938,668, which is a 2.47% decrease from the total budget for the status quo scenario without apixaban. This saving is mainly due to reduced VTE events and bleeds by apixaban. Indeed apixaban is associated with less VTE events (both fatal and non-fatal), less major bleeding and less Clinical Relevant Non Major (CRNM) bleeding with a total of 52 fatal events avoided.CONCLUSIONS: The listing of apixaban for the treatment of VTE (both DVT and PE) and the prevention of recurrent VTE provides both significant clinical advantages, in terms of deaths and events avoided, and economical advantages, consisting in a reduction in the total expenditure on the Italian NHS
[Budget impact analysis of idarucizumab for the management of patients treated with dabigatran in emergency / urgent situations in Italy]
Full text linkBACKGROUND: Each drug therapy with an anticoagulant effect may require, in emergency conditions, a rapid and specific strategy for a prompt restoration of coagulation. Dabigatran is the first-in-class of the so-called new oral anticoagulants (NAO), that have been made available in recent years in addition to traditionally-used vitamin K antagonists (VKA). Idarucizumab is a monoclonal antibody that binds to dabigatran, neutralizing its anticoagulant effect.OBJECTIVE: To assess the economic effect of idarucizumab in patients treated with dabigatran when the rapid reversal of its anticoagulant effect is required.METHODS: The analysis was carried over through the development of a budget impact model specifically adapted to the context of Italian care. The analysis was conducted along a time horizon of five years. The target population was defined by those patients on dabigatran treatment presenting uncontrolled and life-threatening bleedings (gastro-intestinal, intracranial or other) or requiring emergency surgery or urgent procedures. The estimation of healthcare resources (i.e. diagnostic procedures, medications, and other in-hospital services) needed for the management of uncontrolled bleeding and emergency surgery in patients treated with dabigatran was obtained from a panel of five Italian Clinical Experts. Unit costs were derived from current prices and tariffs.RESULTS: The total cost of management with the current therapeutic modalities ranged from € 16.5 million in year 1 to € 20.1 million in year 5. In the scenario with idarucizumab the total cost ranged from € 15.4 million in year 1 to € 18.7 million in year 5. The adoption of idarucizumab resulted in a cumulative 5-year savings of 6.5 million euro corresponding to 7.1% of the total expense.CONCLUSION: Idarucizumab for the management of patients treated with dabigatran in emergency / urgent situations has the potential for substantial savings, compared to treatments currently available. This preliminary assessment will require further confirmatory evidence when the product will become available in Italian healthcare setting.[Article in Italian
[Cost-minimization analysis of replacement therapy in the treatment of von Willebrand disease]
Full text linkBACKGROUND: Replacement therapy with von Willebrand factor (VWF)/factor VIII (FVIII) concentrates represents an effective approach for patients with von Willebrand disease (VWD) who are unresponsive to desmopressin. However, various concentrates are available, with heterogeneous VWF content and VWF/FVIII ratio.AIM: To compare the costs associated to the replacement therapy with VWF/FVIII concentrates in Italy.METHODS: A cost-minimization analysis was performed to compare the pharmaceutical costs per patient of alternatives available for replacement therapy of VWD in the prospective of the Italian National Health Service. For each alternative the analysis calculated the number of vials, and relative costs, required to reach the target levels of VWF:RCo in patients who undergone to major surgery, minor surgery, spontaneous bleeding and prophylaxis.RESULTS: Haemate P® is associated with the lowest FVIII dosage, numbers of vials used and costs in all the clinical situations and at all the dosages considered. With Haemate P® the average costs in major surgery, minor surgery, spontaneous bleeding, and prophylaxis was € 710.94, € 592.45, € 473.96, and € 592.45, respectively. While the costs associated to Fanhdi®, Wilate®, and Wilfactin® was: € 1,309.28, € 1,071.23, € 952.20, and € 1,190.25; € 1,512.45, € 1,344.40, € 1,176.35, and € 1,344.40; € 3,814.09, € 3,269.22, € 3,269.22, and € 3,814.09.CONCLUSIONS: Treatment with Haemate P®, which presents a low FVIII content, allows to reach the target level of VWF:RCo with a lower number of vials and lower costs for the NHS.[Article in Italian
[Budget impact analysis of empagliflozin for the treatment of type 2 diabetes in Italy]
Full text linkBACKGROUND: Empagliflozin is the most recent molecule in the SGLT-2i class, new antidiabetic drugs that reduce renal glucose absorption by determining the excretion in the urine. The high prevalence of T2D, the chronicity of the condition and the severe economic and social burden caused by the disease, impose the need for a careful health economic assessment on each therapeutic innovation in this area.AIM: The aim of this study was to assess the budget impact of adopting empagliflozin in the diabetic population currently treated with sulfonylureas and potentially eligible for treatment with SGLT-2i.METHODS: The budget impact analysis was conducted from the perspective of the Italian National Health Service over a period of three years, through an analytic model developed in MS Excel. The target population was estimated in about 170,000 patients currently treated with sulfonylureas, based on the growth forecasts of the Italian population, epidemiological estimates and drug-use information available in the literature on diabetes in Italy. In the base case was assumed a replacement rate of sulfonylureas equal to 10%, 20% and 30% respectively at the first, second and third year of analysis. A scenario analysis was considered assuming a constant uptake of 100% since the first year. The following direct healthcare costs were considered: 1) acquisition of antidiabetic drugs as the main therapy and as rescue therapy; 2) self-monitoring of blood glucose; 3) management of severe hypoglycemic events and 4) management of major cardiovascular events. Clinical effectiveness data was based on the published literature and unit costs were derived from current prices and tariffs. Oneway sensitivity analysis was developed to assess the impact of input’s uncertainty on the overall result.RESULTS: The base case analysis presented a substantially neutral impact on the budget. The 3-year cumulative impact was -454.337 €, corresponding to a 0.1% saving. This means that the replacement of sulphonylureas with empagliflozin determines an increase in acquisition costs of drugs, which is entirely offset by the reduction in costs of self-monitoring of blood glucose, management of hypoglycemic events and cardiovascular events. The scenario analysis, based on the assumption of a full substitution of sulphonylureas with empagliflozin at the first year, yielded a more enhanced savings. The cumulative impact was -2.269.517 €, corresponding to a 0.6% saving.CONCLUSIONS: The present study shows that the replacement of sulfonylureas (a class of generic products) with empagliflozin, motivated by the advantageous efficacy and safety profile, can take place optimizing healthcare expenditure for the management of DT2.[In Italian
[Pegylation and interferons in multiple sclerosis]
Full text linkPegylation is a procedure used for drug development since the 1970s and consists of the conjugation of a polyethylene glycol molecule (PEG) to a drug. PEG has shown to be safe and effective in improving the pharmacokinetic and pharmacodynamic profile of drugs. Recently, a 20 kDa linear chain of PEG was conjugated to interferon beta-1a with the aim to offer a new treatment option to relapsing-remitting multiple sclerosis (RRMS) patients. Due to a prolonged bioavailability, this new drug can be administered less frequently (every two weeks) than the other interferons beta available, thus allowing to hypothesize a better adherence to the treatment, which, in turn, should result in better clinical and economic outcomes. A phase III clinical trial has proven its effectiveness compared to placebo in RRMS patients, as well as a safety profile comparable to that found in other interferon beta preparations. The immunogenicity of this new molecule is < 1%, thus minimizing the suppression or reduction of interferon beta biological activity that could come from the development of Neutralizing Antibodies (NAbs).[Article in Italian
[Clinical and economic evaluation of the introduction of the combinazion trametinib + dabrafenib in the management of advanced melanoma in the Italian market]
No full textMelanoma is the most aggressive type of all skin cancers. In Italy the incidence is increasing both in men and in women with 13,800 new cases expected in 2016. The advanced melanoma therapy has changed in recent years with the use of immunotherapy and targeted therapies. In particular, treatment with BRAF inhibitors in patients with advanced BRAF V600 mutated melanoma has shown high rates of rapid response and survival. Due to development of acquired resistance with disease progression the rapid response observed with BRAF inhibitor therapy is not long lasting. Combining a BRAF inhibitor with a MEK inhibitor may help to delay the development of resistance and to enhance the antitumor activities with a further increase in the response and survival rate. Trametinib, an inhibitor of MEK kinases, and dabrafenib, an inhibitor of BRAF kinase, have authorizations as monotherapies and in combination with each other for treating adults with unresectable or metastatic melanoma with BRAF V600 mutation. Purpose of this report is to describe the combination in terms of clinical efficacy, safety, and economic impact. In particular, a cost-effectiveness analysis and a budget impact analysis were performed in order to evaluate the combination versus monotherapy and the financial sustainability of trametinib + dabrafenib on the Italian market.[In Italian
