AbstractAims: Protocol T (NCT01627249) was a head-to-head study conducted by the Diabetic Retinopathy Clinical Research Network that compared intravitreal aflibercept, bevacizumab, and ranibizumab for the treatment of diabetic macular edema (DME). A cost-effectiveness analysis accompanying the 1-year data of Protocol T revealed that aflibercept was not cost-effective vs ranibizumab for all patients, but could have been cost-effective in certain patient sub-groups if the 1-year results were extrapolated out to 10?years. The present study evaluated the cost-effectiveness of US Food and Drug Administration-approved anti-vascular endothelial growth factor agents (ranibizumab, aflibercept) for treatment of DME using the 2-year data from Protocol T.Methods: Costs of aflibercept 2.0?mg or ranibizumab 0.3?mg, visual acuity (VA)-related medical costs, and quality-adjusted life-years (QALYs) were simulated for eight VA health states. Treatment, adverse event management, and VA-related healthcare resource costs (2016 US dollars) were based on Medicare reimbursement and published literature. VA-related health utilities were determined using a published algorithm. Patients were stratified by baseline VA: 20/40 or better; 20/50 or worse.Results: Total 2-year costs were higher, and QALYs similar, for aflibercept vs ranibizumab in the full cohort ($44,423 vs $34,529; 1.476 vs 1.466), 20/40 or better VA sub-group ($40,854 vs $31,897; 1.517 vs 1.519), and 20/50 or worse VA sub-group ($48,214 vs $37,246; 1.433 vs 1.412), respectively. Incremental cost-effectiveness ratios in the full cohort and 20/50 or worse VA sub-group were $986,159/QALY and $523,377/QALY, respectively. These decreased to $711,301 and $246,978 when analyses were extrapolated to 10?years.Limitations: Key potential limitations include the fact that VA was the only QALY parameter analyzed and the uncertainty surrounding the role of better- and worse-seeing eye VA in overall functional impairment.Conclusions: This analysis suggests that aflibercept is not cost-effective vs ranibizumab for patients with DME, regardless of baseline vision. 相似文献

AbstractObjective:The objective of the study was to conduct a systematic review of utility weight estimates relevant to economic models for wet age-related macular degeneration (wAMD).Methods:A systematic literature search of PubMed, Embase, the Cochrane Library, and EconLit was performed (January 1995–December 2010) and then updated (October 2010–May 2012; February 2012–July 2013) identifying articles reporting utilities in patients with wAMD and visual impairment. Extracted studies were also assessed for compliance with the NICE reference case.Results:Of 2415 articles identified from the searches, 212 articles were reviewed in full, and 17 selected for data extraction. Most studies used time trade-off (TTO) techniques to estimate utilities; other methods included standard gamble, EuroQoL Health Questionnaire 5 Dimensions (EQ-5D); Short-Form 6D Health Status Questionnaire (SF-6D); and Health Utilities Index Mark III (HUI3). Correlation between utility estimates and visual acuity (VA) differed between the instruments. Time trade-off methods were more sensitive to VA changes than standard gamble methods. HUI3 estimates were most highly correlated with VA changes, followed by TTO; no trend was observed between VA and EQ-5D or SF-6D utility weights. Six of the 17 studies complied with the NICE reference case.Conclusions:Several instruments have been used to elicit utilities from patients with wAMD. Because TTO methods were more sensitive to VA changes than standard gamble and HUI3 estimates were most highly correlated with VA changes, TTO and HUI3 may be suitable methods for economic evaluations in these patients. The EQ-5D and SF-6D were poor indicators of the impact of VA on HRQL. 相似文献

AbstractAims: Allopurinol is the most common urate lowering therapy (ULT) used to treat gout but may cause life-threatening severe cutaneous adverse reactions (SCAR) in a small number of patients. Risk of SCAR is increased for patients with the HLA-B*58:01 genotype. When alternative ULT is required, febuxostat or probenecid are recommended. The aim of this study was to conduct a cost-utility analysis of sequential ULT treatment strategies for gout, including strategies with and without HLA-B*58:01 genotyping prior to treatment initiation, with a view to inform optimal gout management in Singapore.Materials and methods: A Markov model was developed from the Singapore healthcare payer perspective. Reflecting local practice, 12 different treatment strategies containing at least one ULT (allopurinol, febuxostat, probenecid) were evaluated in adults with gout. Response rates (SUA < 6mg/dL) were derived from an in-house network meta-analysis and from published literature. Incremental cost-effectiveness ratios (ICERs) were calculated over a 30-year time horizon, with costs and benefits discounted at 3% per annum. Sensitivity analyses were conducted to explore uncertainties.Results: Sequential treatment of allopurinol 300?mg/day-allopurinol 600?mg/day-probenecid (“standard of care”) was cost-effective compared to no ULT, with an ICER of SGD1,584/QALY. Allopurinol300-allopurinol600-probenecid-febuxostat sequence compared to allopurinol300-allopurinol600-probenecid had an ICER of SGD11,400/QALY. All other treatment strategies were dominated by preceding strategies. Treatment strategies incorporating HLA-B*58:01 genotyping before ULT use were dominated by the corresponding non-genotyping strategy.Conclusions: Current standard of care (allopurinol300-allopurinol 600-probenecid) for gout is cost-effective compared with no ULT in the local context. Febuxostat is unlikely to be cost-effective in Singapore at current prices unless it is used last-line. 相似文献

Objective: The study evaluates the cost-effectiveness of secukinumab, a fully human monoclonal antibody that selectively neutralizes interleukin (IL)-17A, vs currently licensed biologic treatments in patients with active psoriatic arthritis (PsA) from a Canadian healthcare system perspective.Methods: A decision analytic semi-Markov model evaluated the cost-effectiveness of secukinumab 150?mg and 300?mg compared to subcutaneous biologics adalimumab, certolizumab pegol, etanercept, golimumab, and ustekinumab, and intravenous biologics infliximab and infliximab biosimilar in biologic-naive and biologic-experienced patients over a lifetime horizon. The response to treatments was evaluated after 12 weeks by PsA Response Criteria (PsARC) response rates. Non-responders or patients discontinuing initial-line of biologic treatment were allowed to switch to subsequent-line biologics. Model input parameters (Psoriasis Area Severity Index [PASI], Health Assessment Questionnaire [HAQ], withdrawal rates, costs, and resource use) were collected from clinical trials, published literature, and other Canadian sources. Benefits were expressed as quality-adjusted life years (QALYs). An annual discount rate of 5% was applied to costs and benefits. The robustness of the study findings were evaluated via sensitivity analyses.Results: Biologic-naive patients treated with secukinumab achieved the highest number of QALYs (8.54) at the lowest cost (CAD 925,387) over a lifetime horizon vs all comparators. Secukinumab dominated all treatments, except for infliximab and its biosimilar, which achieved minimally more QALYs (8.58). However, infliximab and its biosimilar incurred more costs than secukinumab (infliximab: CAD 1,015,437; infliximab biosimilar: CAD 941,004), resulting in higher cost-effectiveness estimates relative to secukinumab. In the biologic-experienced population, secukinumab dominated all treatments as it generated more QALYs (8.89) at lower costs (CAD 954,692). Deterministic sensitivity analyses indicated the results were most sensitive to variation in PsARC response rates, change in HAQ, and utility values in both populations.Conclusions: Secukinumab is either dominant or cost-effective vs all licensed biologics for the treatment of active PsA in biologic-naive and biologic-experienced populations in Canada. 相似文献
