RESUMO
BACKGROUND AND AIM: Thrombocytopenia is a frequent hematological condition in chronic liver disease (CLD) patients increasing the risk of bleeding in patients undergoing invasive procedures. Without an alternative, clinical guidelines recommended the use of platelet transfusion (PT) prior to procedure to prevent this bleeding risk. Lusutrombopag (LUSU), an orally active, small-molecule thrombopoietin receptor agonist, was developed as an alternative to PT. The objective of this study was to evaluate a cost-effectiveness of LUSU as a potential alternative to PT in Japan. METHODS: A cost-effectiveness analysis of LUSU relative to PT was conducted by a simulation model consisting of a decision tree combined to Markov model. Quality-adjusted life years (QALYs) were used as an indicator of efficacy, and the analysis was conducted from the Japanese public healthcare payer's perspective. The time horizon of the analysis was 50 years (a lifetime) and the discount rate was set at 2%. RESULTS: LUSU gained 6.1803 QALYs with an expected lifetime costs of 2 380 219 JPY compared to PT with 6.1712 QALYs gained and expected lifetime costs of 2 382 908 JPY. Thus, LUSU was deemed dominant compared with PT. Based on probabilistic analyses, the chance of LUSU being dominant and the incremental cost-effectiveness ratio being below 5 million JPY/QALY was estimated at 51.8% and 78.3%, respectively, demonstrating the robustness of the results. CONCLUSIONS: LUSU was evaluated as an efficacious and cost-saving treatment option for Japanese CLD patients with thrombocytopenia who required a planned invasive procedure compared with PT and economically should be considered as an alternative treatment.
RESUMO
BACKGROUND: Local oestrogens, the current treatment for vulvar and vaginal atrophy (VVA), are not suitable for all women. Standard of care (SoC) consists of over-the-counter lubricants and moisturisers. Senshio® (ospemifene) provides a treatment option for postmenopausal women who are not candidates for local vaginal oestrogen therapy who would otherwise have an unmet clinical need. OBJECTIVES: The aim of this study was to estimate the cost-effectiveness of ospemifene, a selective oestrogen receptor modulator, for the treatment of moderate to severe symptomatic VVA in postmenopausal women who are not candidates for local vaginal oestrogen therapy. METHODS: The Scottish Medicines Consortium (SMC) recently evaluated the clinical and cost-effectiveness evidence of ospemifene plus SoC compared with SoC alone. A cost-effectiveness study, from a National Health Service (NHS) Scotland perspective over a lifetime time horizon, was submitted to the SMC. The cohort-based Markov model used robust clinical evidence from two large pivotal phase III randomised controlled studies and included four health states classified by dyspareunia symptom severity: none, mild, moderate and severe. The movement of women between health states was dependent on the effectiveness of treatment in reducing dyspareunia. Extensive sensitivity analyses were undertaken to assess the level of confidence associated with the base-case results. RESULTS: Treatment with ospemifene was associated with an additional cost of £847 per patient and an increase in quality-adjusted life-years (QALY) of 0.06 per patient. Ospemifene had an incremental cost-effectiveness ratio of £14,138 per QALY. In the probabilistic sensitivity analysis, there was a probability of 89% that ospemifene was cost-effective at a threshold of £20,000 per QALY gained. Ospemifene remained cost-effective under all scenario analyses. The SMC reviewed the clinical and economic evidence and judged that the evidence demonstrated a robust case to support prescribing ospemifene in NHS Scotland. CONCLUSION: Ospemifene is a cost-effective intervention that has recently been accepted by the SMC for the treatment of postmenopausal women with moderate to severe VVA who are not candidates for local oestrogen.

BACKGROUND: There are few published health technology assessments that have included the impact of a disease or treatment on caregivers' health related quality of life (HRQL). The objectives of this study were to explore the overall HRQL of caregivers of people with Multiple Sclerosis compared to matched controls, and more specifically explore the impact of different levels of functioning in people with MS on caregivers' HRQL scores. METHODS: A cross sectional observational study conducted as an online survey was undertaken in the UK. 200 caregivers of people with MS and 200 matched controls completed the EQ-5D, SF-36, HADS and a socio-demographic questionnaire. Caregivers also completed the Patient Determined Disease Steps questionnaire as a measure of MS severity. Differences in HRQL between caregivers and controls were assessed using t-tests and chi square analyses as appropriate. Ordinary Least Squares regression was also used to evaluate the disutility of being a caregiver compared to controls stratified by MS severity. RESULTS: Caregivers reported significantly lower HRQL, as measured by the SF-36, HADS and EQ-5D, compared to matched controls. A lower level of functioning in people with MS was mirrored by lower levels of caregivers' HRQL. At the point at which mobility problems required wheelchair use caregivers reported better HRQL. CONCLUSIONS: The potential impact of caregiving on HRQL is an important consideration for economic evaluations. In relation to MS, the results suggest that caregiver's HRQL deteriorates as the people with MS lose functioning; thus treatments that delay loss of function may have a benefit for caregivers as well as patients.

OBJECTIVE: To assess the cost-effectiveness of subcutaneous interferon (sc IFN) beta-1a 44 mcg 3-times weekly (tiw) vs no treatment at reducing the risk of conversion to multiple sclerosis (MS) in patients with clinically isolated syndrome (CIS) in Sweden. METHODS: A Markov model was constructed to simulate the clinical course of patients with CIS treated with sc IFN beta-1a 44 mcg tiw or no treatment over a 40-year time horizon. Costs were estimated from a societal perspective in 2012 Swedish kronor (SEK). Treatment efficacy data were derived from the REFLEX trial; resource use and quality-of-life (QoL) data were obtained from the literature. Costs and outcomes were discounted at 3%. Sensitivity analyses explored whether results were robust to changes in input values and use of Poser criteria. RESULTS: Using McDonald criteria sc IFN beta-1a was cost-saving and more effective (i.e., dominant) vs no treatment. Gains in progression free life years (PFLYs) and quality-adjusted life-years (QALYs) were 1.63 and 0.53, respectively. Projected cost savings were 270,263 SEK. For Poser criteria cost savings of 823,459 SEK were estimated, with PFLY and QALY gains of 4.12 and 1.38, respectively. Subcutaneous IFN beta-1a remained dominant from a payer perspective. Results were insensitive to key input variation. Probabilistic sensitivity analysis estimated a 99.9% likelihood of cost-effectiveness at a willingness-to-pay threshold of 500,000 SEK/QALY. CONCLUSION: Subcutaneous IFN beta-1a is a cost-effective option for the treatment of patients at high risk of MS conversion. It is associated with lower costs, greater QALY gains, and more time free of MS. LIMITATIONS: The risk of conversion from CIS to MS was extrapolated from 2-year trial data. Treatment benefit was assumed to persist over the model duration, although long-term data to support this are unavailable. Cost and QoL data from MS patients were assumed applicable to CIS patients.
