    Abstract Objective: To review the survival modelling used in cost-effectiveness studies evaluating an interventional procedure and to discuss implications for decision-makers.
    Design: A case study of three economic evaluations that each used immature data from the EVEREST II High Surgical Risk (HSR) Study of transcatheter edge-to-edge repair (TEER) for patients with severe mitral regurgitation (MR) who were at high risk of surgery.
    Setting: Estimation of patient survival in cost-effectiveness studies.
    Participants: The EVEREST II HSR Study included 78 patients who had TEER of the mitral valve using the MitraClip device and a retrospectively identified control group of 36 patients who received medical management and were followed up for 12 months. Observed survival (TEER arm only) was updated at 5 years.
    Results: Two studies used 12-month observed mortality from EVEREST II HSR to model survival over lifetime horizons. Observed and modelled survival were associated with considerable uncertainty due to short follow-up and small numbers of participants. Modelling control patients' survival required an approximate 10-fold extrapolation based on 12-month observation of only 38 patients. Observed 5-year survival in the TEER group differed from that less mature follow-up suggesting that survival modelling based on shorter follow-up was unsatisfactory. No public domain data for the control group are available beyond 12-month follow-up so meaningful estimates using mature data for both arms are currently not possible. A third study developed survival models using incompletely reported transitions between MR grades in EVEREST II HSR and mortality rates observed for different MR grades derived from a study in an unrelated population.
    Conclusions: Modelling survival in such small samples followed up for only 12 months is associated with great uncertainty, and cost-effectiveness results based on these analyses should be viewed as premature and used cautiously in reimbursement decisions.

    Abstract When updated clinical trial data becomes available reassessing the cost-effectiveness of technologies may modify estimates and influence decision-making. We investigated the impact of updated trial outcomes on the cost-effectiveness of percutaneous mitral repair (PR) for secondary mitral regurgitation. We updated our previous three-state time-varying Markov model to assess the cost-effectiveness of PR + guideline directed medical treatment (GDMT) versus GDMT alone. Key clinical inputs (overall survival (OS) and heart failure hospitalisations (HFH)) were obtained using the 3-year trial findings from the COAPT (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy) RCT. We calculated incremental cost-effectiveness ratios (ICER) and report how these differ between analyses based on early (2-year) and updated (3-year) evidence. Updated trial data showed an increase in mortality in the intervention arm between two and three years follow-up that was not seen in the control arm. Deterministic and multivariate cost-effectiveness modelling yielded incremental cost effectiveness ratios ICERs of €38,123 and €31,227 /QALY. Compared to our 2-year based estimate (€21,918 / QALY) these results imply an approximate 1.5-fold increase in ICER. The availability of updated survival analyses from the COAPT pivotal trial suggests previous estimates based on 2-year trial findings were over optimistic for the intervention.

    Abstract Background: Cost-effectiveness analyses of treatments for glioblastoma multiforme (GBM) have mostly used state transition Markov models with time invariant transition probabilities (TIMMs). In three case studies of GBM treatments, we compared Partitioned Survival model (PSM) results with published outputs from TIMMs.
    Methods: PSMs used the same RCT data sources, utility values, time horizons, cycle times and annual discounting used in published TIMMs. Reported overall survival and progression-free survival plots were digitised and fitted with a range of parametric models. Economic model outputs were generated in the same form as reported for the TIMMs. PSM output uncertainty was explored in univariate and in multivariate sensitivity analyses.
    Results: PSMs generated incremental cost-effectiveness ratios that were different to the published TIMMs. The magnitude of difference was substantial in two cases. The PSMs were reasonably robust and in sensitivity analyses were sensitive to variations in the same model inputs as were the TIMMs. When compared to the RCT data, the TIMMs tended to generate underestimates of the likely overall survival gain. TIMM estimates for depletion of individuals from the stable disease state and for accumulation in the dead state had relatively poor resemblance to the source RCT data.
    Conclusion: TIMMs delivered different cost-effectiveness estimates to PSMs; in two cases, TIMMs produced substantially lower ICER values than PSMs. Model output differences appear attributable to less realistic cost-and-benefit estimates generated in TIMMs due to rapid depletion from the stable disease state and/or accumulation in the dead state.

    Abstract Objectives: Before an intervention is publicly funded within the United Kingdom, the cost-effectiveness is assessed by the National Institute of Health and Care Excellence (NICE). The efficacy of an intervention across the patients' lifetime is often influential of the cost-effectiveness analyses, but is associated with large uncertainties. We reviewed committee documents containing company submissions and evidence review group (ERG) reports to establish the methods used when extrapolating survival data, whether these adhered to NICE Technical Support Document (TSD) 14, and how uncertainty was addressed.
    Methods: A systematic search was completed on the NHS Evidence Search webpage limited to single technology appraisals of cancer interventions published in 2017, with information obtained from the NICE Web site.
    Results: Twenty-eight appraisals were identified, covering twenty-two interventions across eighteen diseases. Every economic model used parametric curves to model survival. All submissions used goodness-of-fit statistics and plausibility of extrapolations when selecting a parametric curve. Twenty-five submissions considered alternate parametric curves in scenario analyses. Six submissions reported including the parameters of the survival curves in the probabilistic sensitivity analysis. ERGs agreed with the company's choice of parametric curve in nine appraisals, and agreed with all major survival-related assumptions in two appraisals.
    Conclusions: TSD 14 on survival extrapolation was followed in all appraisals. Despite this, the choice of parametric curve remains subjective. Recent developments in Bayesian approaches to extrapolation are not implemented. More precise guidance on the selection of curves and modelling of uncertainty may reduce subjectivity, accelerating the appraisal process.

    Abstract Purpose: Two randomized controlled trials (RCTs), Mitra-Fr and Coapt, evaluating the benefit of percutaneous repair (PR) for heart failure (HF) patients with severe mitral regurgitation, have led to conflicting results. We aimed to evaluate the impact of these trial results on the cost-effectiveness of PR using effectiveness inputs from the two RCTs.
    Methods: We developed a time varying Markov type model with three mutually exclusive health states: alive without HF hospitalisation, alive with HF hospitalisation, and dead. Clinically plausible extrapolations beyond observed data were obtained by developing parametric modelling for overall survival and HF hospitalisations using published data from each trial. We adopted the perspective of the French Health System and used a 30-year time horizon. Results were expressed as € / quality-adjusted life year (QALY) gained using utility inputs from literature.
    Findings: Results are presented using treatment efficacy measures from Mitra-F and Coapt trials respectively. With the Mitra-Fr data, after annual discounting, the base case model generated an incremental 0.00387 QALY at a cost of €25,010, yielding an incremental cost effectiveness ratio (ICER) of €6,467,032 / QALY. The model was sensitive to changes made to model inputs. There was no potential of PR being cost-effective. With the Coapt data, the model generated 1.19 QALY gain at a cost of €26,130 yielding an ICER of €21,918 / QALY and at a threshold of >€50,000/QALY PR had a probability of 1 of being cost-effective.
    Implications: Cost effectiveness results were conflicting; reconciling differences between trials is a priority and could promote optimal cost effectiveness analyses and resource allocation.

    Abstract Objectives: Nusinersen (Spinraza®, Biogen) and onasemnogene abeparvosec (Zolgensma®, Novartis) are novel gene-based therapies for the orphan disease Spinal Muscular Atrophy. Onasemnogene abeparvosec has been allocated an acquisition cost of up to US$5 million per patient. We undertook a rapid inquiry to evaluate if onasemnogene abeparvosec is likely to be cost-effective for the UK NHS.
    Methods: We used publicly available cost-effectiveness data and recommended methodology to perform cost-utility evaluation of onasemnogene abeparvosec versus best supportive care and nusinersen.
    Results: Our evaluations highlight wide variations in cost and benefit estimates of nusinersen and indicate that onasemnogene abeparvosec is unlikely to represent value for money according to current standards of reimbursement. Results are discussed in the context of reimbursement decisions for orphan diseases.
    Conclusion: Commonly implemented commercial confidentiality practices combined with uncertain data obscure scrutiny and justification of past and present reimbursement decisions for orphan drugs. Future cutting edge expensive therapies will be numerous, they will entail very substantial economic strains. We conclude that there is an urgent and increasing need for the development of improved procedures that can lead to equitable, consistent, and transparent decision-making.

    Abstract Purpose: A first cost-effectiveness analysis has raised a strong concern regarding the cost of tumor treatment fields (TTF) added to maintenance temozolomide for patients with glioblastoma. This evaluation was based on effectiveness outcomes from an interim analysis of the pivotal trial, moreover it used a "standard" Markov model. Our objective was to update the cost-effectiveness evaluation using the more flexible potential of the "partitioned survival" model design and using the latest effectiveness data.
    Methods: We developed the model with three mutually exclusive health states: stable disease, progressive disease, and dead. Good fit parametric models were developed for overall survival and progression free survival and these generated clinically plausible extrapolations beyond the observed data. We adopted the perspective of the French national health insurance and used a 20-year time horizon. Results were expressed as cost/life-years (LY) gained (LYG).
    Results: The base case model generated incremental benefit of 0.604 LY at a cost of €453,848 which, after 4% annual discounting of benefits and costs, yielded an incremental cost effectiveness ratio (ICER) of €510,273/LYG. Using sensitivity analyses and bootstrapping methods results were found to be relatively robust and were only sensitive to TTF device costs and the modelling of overall survival. To achieve an ICER below €100,000/LYG would require a reduction in TTF device cost of approximately 85%.
    Conclusions: Using a different type of model and updated survival outcomes, our results show TTF remains an intervention that is not cost-effective, which greatly restrains its diffusion to potentially eligible patients.

    Abstract Introduction: Ocrelizumab is the first approved drug for primary progressive multiple sclerosis. Following appraisal by health technology assessment (HTA) bodies, this medicine has not been widely covered across European countries. We have compared the HTA process in England and France.
    Area covered: We undertook an analysis of relevant documents that were published by the two HTA bodies. We analyzed patients' availability of Ocrelizumab at the different stages of the process.
    Expert opinion: We identified differences in the assessment, one being the use of a different population of the pivotal trial, which has resulted in the consideration of distinct clinical effectiveness estimates. Ocrelizumab became available earlier in France as part of an early access program. However, rapid access was discontinued for newly eligible patients following an opinion concluding that Ocrelizumab yielded no additional benefit over placebo. This opinion was not compatible with the criteria allowing reimbursement in France.In England, there was no early access program and following an appraisal that included cost-effectiveness evaluation combined with pricing agreements, medicine was finally recommended. In conclusion, differences in the HTA process may result in appreciable differences in timing and outcome from marketing authorization to the adoption of newly licensed drugs.
