Cost-utility of ranibizumab versus aflibercept for treating Greek patients with visual impairment due to diabetic macular edema.

BACKGROUND: To conduct a cost-utility analysis of ranibizumab versus aflibercept for the treatment of patients with visual impairment due to diabetic macular edema (DME) in the Greek setting. METHODS: A Markov model was adapted to compare the use of ranibizumab 0.5 mg (pro re nata-PRN and treat and extend-T&E) to aflibercept 2 mg (every 8 weeks after five initial doses) in DME. Patients transitioned at a 3-month cycle among nine specified health states (including death) over a lifetime horizon. Transition probabilities, utilities, as well as DME-related mortality were extracted from relevant clinical trials, a network meta-analysis and other published studies. The analysis was conducted from payer perspective and as such only costs reimbursed by the payer were considered (year 2014). The incremental cost per quality-adjusted life year (QALY) gained and the net monetary benefit was the main outcome measures. RESULTS: Τhe use of PRN and T&E ranibizumab regimens were shown to be cost saving comparing to aflibercept (by €2824 and €22, respectively), and more beneficial in terms of QALYs gained (+0.05) and time without visual impairment (0.031 and 0.034 years), thereby dominating aflibercept. Moreover, ranibizumab used as PRN or T&E resulted in a net monetary benefit of €3984 and €1278, respectively. CONCLUSIONS: Both PRN and T&E ranibizumab regimens were more beneficial and less costly compared to aflibercept for the management of DME. Hence, ranibizumab seems to be a dominant option for the treatment of visual impairment due to DME in the Greek setting.

A systematic review and meta-analysis of the epidemiology and burden of venous thromboembolism among pregnant women.

BACKGROUND: Pregnancy-related venous thromboembolism (VTE) is one of the leading causes of maternal morbidity and mortality. OBJECTIVES: To review the epidemiology, and humanistic and economic burden of pregnancy-related VTE. SEARCH STRATEGY: Medline, the Cochrane Central Register of Controlled Trials, Econlit, Science Direct, JSTOR, Oxford Journals, and Cambridge Journals were searched for reports published between January 2000 and December 2012. Keywords related to VTE, pregnancy, and epidemiology and the humanistic and economic burdens were combined. SELECTION CRITERIA: Eligible studies evaluated the incidence, mortality, recurrence, complications, quality-of-life, and economic burden of VTE among pregnant women, and had been published in English. DATA COLLECTION AND ANALYSIS: Background information of the study, participants' characteristics, and study outcomes were collected. Meta-analyses of data were performed. MAIN RESULTS: Twenty studies were included, none of which investigated the economic burden. The pooled overall incidence of pregnancy-related VTE was 1.2 per 1000 deliveries. The pooled VTE case fatality rate was 0.68% and the recurrence rate was 4.27%. The pooled risk of major bleeding was 1.05%. Post-thrombotic syndrome seemed to have a negative effect on quality of life. CONCLUSIONS: Although the incidence of VTE was found to be relatively low during pregnancy and the postpartum period, the clinical burden is high. Further research is required to assess the economic burden of pregnancy-relate VTE.

Everolimus plus exemestane versus bevacizumab-based chemotherapy for second-line treatment of hormone receptor-positive metastatic breast cancer in Greece: An economic evaluation study.

BACKGROUND: The objective of our study was to conduct a cost-effectiveness (CE) study of combined everolimus (EVE) and exemestane (EXE) versus the common clinical practice in Greece for the treatment of postmenopausal women with HR+/HER2- advanced breast cancer (BC) progressing on nonsteroidal aromatase inhibitors (NSAI). The combinations of bevacizumab (BEV) plus paclitaxel (PACL) and BEV plus capecitabine (CAPE) were selected as comparators. METHOD: A Markov model, consisting of three health states, was used to describe disease progression and evaluate the CE of the comparators from a third-party payer perspective over a lifetime horizon. Efficacy and safety data as well as utility values considered in the model were extracted from the relevant randomized Phase III clinical trials and other published studies. Direct medical costs referring to the year 2014 were incorporated in the model. A probabilistic sensitivity analysis was conducted to account for uncertainty and variation in the parameters of the model. Primary outcomes were patient survival (life-years), quality-adjusted life years (QALYs), total direct costs and incremental cost-effectiveness ratios (ICER). RESULTS: The discounted quality-adjusted survival of patients treated with EVE plus EXE was greater by 0.035 and 0.004 QALYs, compared to BEV plus PACL and BEV plus CAPE, respectively. EVE plus EXE was the least costly treatment in terms of drug acquisition, administration, and concomitant medications. The total lifetime cost per patient was estimated at €55,022, €67,980, and €62,822 for EVE plus EXE, BEV plus PACL, and BEV plus CAPE, respectively. The probabilistic analysis confirmed the deterministic results. CONCLUSION: Our results suggest that EVE plus EXE may be a dominant alternative relative to BEV plus PACL and BEV plus CAPE for the treatment of HR+/HER2- advanced BC patients failing initial therapy with NSAIs.

The humanistic and economic burden of venous thromboembolism in cancer patients: a systematic review.

The objective of this study was to present evidence on the epidemiology, health outcomes and economic burden of cancer-related venous thromboembolism (VTE). Medline, Cochrane Central Register of Controlled Trials, Econlit, Science Direct, JSTOR, Oxford Journals and Cambridge Journals were searched. The systematic literature search was limited to manuscripts published from January 2000 to December 2012. On the basis of the literature, cancer patients experience between two-fold and 20-fold higher risk of developing VTE than noncancer patients. They are more likely to experience a VTE event during the first 3-6 months after cancer diagnosis. In addition, an increased risk of VTE in patients with distant metastases and certain types of cancer (i.e. pancreatic or lung) was revealed. VTE was found to be a leading cause of mortality in cancer patients. The annual average total cost for cancer patients with VTE was found to be almost 50% higher than that of cancer patients without VTE. Inpatient care costs accounted for more than 60% of total cost. The existing evidence assessed in the present review demonstrated the significant health and economic consequences of cancer-related VTE, which make a strong case for the importance of its proper and efficient prevention and management.
