Introduction/objectives: Lesinurad, in combination with allopurinol, has been approved for treatment of patients with gout which do not reach therapeutic serum urate target with xanthine oxidase inhibitors monotherapy. The study aimed to assess the incremental cost-effectiveness ratio of adding lesinurad to allopurinol as second-line therapy, compared to febuxostat for patients with gout in Spain., Method: A Markov model representing disease evolution was used to estimate the lifetime accumulated cost and benefits in terms of quality-adjusted-life-year (QALY). Patients could either continue with second-line treatment with lesinurad (200 mg/daily) plus allopurinol (400 mg/daily) or febuxostat (80 mg/daily) switch to allopurinol monotherapy (271 mg/daily) in case of intolerance or discontinue treatment. The treatment's efficacy captured in the transition probabilities between health states were derived from CLEAR and EXCEL trials. Quality of life related to gout severity and flare frequency was considered by means of utilities. The total cost estimation (€, 2019) included drug acquisition cost, disease monitoring, and flare management cost. Unitary local costs derived from databases and literature. A 3% annual discount rate was applied for cost and outcomes., Results: Lesinurad plus allopurinol provided higher QALYs (14.79) than febuxostat (14.69). Total accrued cost/patient was lower with lesinurad and allopurinol (€50,631.51) versus febuxostat (€56,698.64). Lesinurad plus allopurinol resulted more effective and less costly (dominant option) versus febuxostat., Conclusions: Lesinurad plus allopurinol therapy compared with febuxostat seems an effective option for the management of hyperuricemia in patients who did not reach serum urate target to previous allopurinol monotherapy, associated to cost-savings for the Spanish Health System.Key Points• Lesinurad, in combination with allopurinol, has been recently authorized as second-line treatment of hyperuricemia in gout patients.• Lesinurad plus allopurinol provided higher effectiveness in terms of quality-adjusted-life-years (14.79) than febuxostat (14.69).• Lesinurad plus allopurinol resulted less costly (total cost/per patient) compared with febuxostat.• Lesinurad plus allopurinol resulted a dominant option compared with febuxostat.

Background: Dual urate-lowering therapy (ULT) with lesinurad in combination with either allopurinol or febuxostat is an option for patients with gout unsuccessfully treated on either monotherapy. Treatment failure is often a result of poor medication adherence. Imperfect adherence in clinical trials may lead to biased estimates of treatment effect and confound the results of cost-effectiveness analyses., Objectives: To estimate the impact of varying medication adherence on the cost effectiveness of lesinurad dual therapy and estimate the value-based price of lesinurad at which the incremental cost-effectiveness ratio is equal to £20,000 per quality-adjusted life-year (QALY)., Methods: Treatment effect was simulated using published pharmacokinetic-pharmacodynamic models and scenarios representing adherence in clinical trials, routine practice, and perfect use. The subsequent cost and health impacts, over the lifetime of a patient cohort, were estimated using a bespoke pharmacoeconomic model., Results: The base-case incremental cost-effectiveness ratios comparing lesinurad dual ULT with monotherapy ranged from £39,184 to £78,350/QALY gained using allopurinol and £31,901 to £124,212/QALY gained using febuxostat, depending on the assumed medication adherence. Results assuming perfect medication adherence imply a per-quarter value-based price of lesinurad of £45.14 when used in dual ULT compared with allopurinol alone and £57.75 compared with febuxostat alone, falling to £25.41 and £3.49, respectively, in simulations of worsening medication adherence., Conclusions: The estimated value-based prices of lesinurad only exceeded that which has been proposed in the United Kingdom when assuming both perfect drug adherence and the eradication of gout flares in sustained treatment responders., (Copyright © 2018 ISPOR–The Professional Society for Health Economics and Outcomes Research.

Aim: To estimate budget impact of adopting lesinurad as add-on to allopurinol for urate-lowering therapy in gout. Methods: A budget impact model was developed for a US payer perspective, using a Markov model to estimate costs, survival and discontinuation in a one-million-member health plan. The population included patients failing first-line gout therapy, followed for 5 years. Results: Incremental costs of adding lesinurad versus no lesinurad were US$241,907 and US$1,098,220 in first and fifth years, respectively. Cumulative 5-year incremental cost was US$3,633,440. Estimated incremental mean cost per treated patient with gout per year was US$112. The mean per-member per-month cost increased by US$0.06. Conclusion: Initiating lesinurad would result in an incremental per-member per-month cost of US$0.06 over 5 years.

Background: Until very recently the only therapeutic alternative for the management of patients affected by gout/hyperuricemia that did not respond to a first-line treatment based on allopurinol alone or who cannot tolerate allopurinol was febuxostat, a xanthine oxidase non-purine-selective inhibitor. Lately, however, a new therapeutic alternative has become available for the management of this pathology: lesinurad, a urate transporter inhibitor., Objective: To objective of this study was to evaluate the cost effectiveness of lesinurad/allopurinol in comparison with febuxostat as a second-line therapeutic strategy for the management of patients affected by gout and hyperuricemia that did not respond to a first-line therapy based on allopurinol alone., Methods: A Markov model was built based on the natural history of the pathology; patients entered the model according to their level of serum uric acid concentration and flowed across it according to their response to the therapy. The analysis was carried out considering the perspective of the Italian National Health Service on a lifetime horizon and 6-month cycles. Costs and quality-adjusted life-years (QALYs) were discounted at a 3.5% yearly rate. The results of the model were expressed in terms of incremental cost-effectiveness ratio (ICER). Both a one-way and a multi-way Monte-Carlo analysis were carried out in order to check the robustness of the results achieved., Results: The ICER derived from the comparison was equal to €77.53/QALY on the lifetime horizon, as there was a higher level of costs associated with the combination as compared with febuxostat (€10,658.27 vs. €10,645.87, for a differential of €12.40) and a higher level of QALYs achieved (7.77 vs. 7.61, for a differential of 0.16)., Conclusions: The lesinurad/allopurinol combination is recommended for the treatment of patients affected by gout/hyperuricemia in the Italian Health System as it appears to be cost effective and thus sustainable for the Italian healthcare sector.

Erdosteine is a new thiol compound with effects on bacterial adhesiveness as well as antioxidant and mucoactive properties. The EQUALIFE study, a fully randomized, double-blind, placebo-controlled, parallel-group, multicenter study, was designed to assets the effectiveness of long-term treatment with erdosteine in patients with moderate chronic obstructive pulmonary disease (COPD). One hundred and fifty-five patients received oral erdosteine, 300 mg b.i.d., or placebo for 8 months during the winter season to assess the effect of treatments on exacerbation rate, hospitalization, lung function and quality of life, assessed using the Short Form 36 and the St. George's Respiratory Questionnaire. A pharmacoeconomic analysis was also conducted to compare the two treatments. One hundred and twenty-four patients completed the study with erdosteine (n = 63) or placebo (n = 61). The group of COPD patients who received 8 months of continuous treatment with erdosteine had significantly fewer exacerbations and spent fewer days in the hospital than did the placebo group; furthermore, they had no loss of lung function. Patients in the erdosteine group also showed a significant improvement in health-related quality of life. The mean total COPD-related disease costs per patient were lower in the erdosteine group than in the placebo group over the study period. The results indicate that 8 months of treatment with erdosteine is effective in reducing exacerbation and hospitalization rates and in improving health status. The study suggests that erdosteine is likely to provide an important contribution to the therapy of patients with symptomatic COPD.
