- Aims: To evaluate the cost-effectiveness of adding prolonged-release (PR)-fampridine to best supportive care (BSC) versus BSC alone for the improvement of walking ability in patients with MS. Methods: A cost-utility analysis based on a Markov model was developed to model responders and timed 25-foot walk (T25FW) scores, accumulated costs, and quality-adjusted life-years (QALY) in adults with MS and Expanded Disability Status Scale (EDSS) scores between 4 and 7. The analysis was conducted from a Swedish societal perspective. Results: In the base-case analysis, PR-fampridine plus BSC led to a higher QALY gain than BSC alone. The largest direct cost was professional care provision followed by hospital inpatient stays while the indirect cost was the loss of earnings due to days off work. The incremental cost-effectiveness ratio (ICER) for PR-fampridine plus BSC compared with BSC alone was 57,109 Swedish Kronor (kr)/QALY (€5,607/QALY [1 kr = €0.0981762 on 8 April 2021] and $6,675/QALY [1 kr = $0.116890 on 8 April 2021]). All sensitivity analyses performed resulted in ICERs below 500,000 kr (€49,088 and $58,445). Limitations: Resource use data were not specific to the Swedish market. Conclusions: PR-fampridine represents a cost-effective treatment for MS-related walking impairment in Sweden, due to improvements in patients’ quality of life and reduced healthcare resource utilization. © 2021 Biogen International GmbH.

- Aim: We investigated cost effectiveness of benralizumab vs. standard of care (SOC) plus oral corticosteroids (OCS) for patients with severe, eosinophilic OCS-dependent asthma in Sweden. Materials and methods: A three-state, cohort-based Markov model of data from three Phase III benralizumab clinical trials (ZONDA [NCT02075255], SIROCCO [NCT01928771], and CALIMA [NCT01914757]) was used to assess the incremental cost-effectiveness ratio of benralizumab vs. SOC plus OCS. Health outcomes were estimated in terms of quality-adjusted life-years (QALYs). The model included costs and disutilities associated with extrapolated OCS-related adverse events. Patients with severe asthma were defined as those receiving OCS >= 5 mg/day. Results: Benralizumab demonstrated a cost-effectiveness ratio vs. SOC plus OCS of 2018 Swedish Kronor (SEK) 366,855 (euro34,127) per QALY gained, based on increases of 1.33 QALYs and SEK 488,742 (euro45,344) per patient. Benralizumab treatment costs contributed most to incremental costs. The probability of benralizumab's being cost-effective with willingness-to-pay (WTP) thresholds between SEK 429,972 (euro40,000) and SEK 752,452 (euro70,000) ranged from 75% to 99%. Limitations: Potential limitations of these analyses include the use of combined data from three different clinical trials, a one-way sensitivity analysis that did not include mortality and transition estimates, and Observational & Pragmatic Research Institute (OPRI) data from the UK as a proxy of the Swedish health care system. Conclusions: The results of these analyses demonstrate that benralizumab has a high probability of being cost-effective compared with SOC plus OCS for a subgroup of patients with severe, eosinophilic asthma receiving regular OCS treatment and may support clinicians, payers and patients in making treatment decisions.

- Aim: The aim of the study is to assess the accuracy of overall survival (OS) extrapolations in cost-effectiveness analysis made by the Dental and Pharmaceutical Benefits Agency (TLV) to decide on the reimbursement and use of oncology drugs in Sweden.Material and methods: TLV appraisals for oncology drugs were identified during a 5-year period (2013-2017). To be included each appraisal and health economic model must include a TLV base case extrapolation of OS. Further, Kaplan-Meier (KM) estimates on OS from the original and follow-up clinical trials must be available. Potential follow-up trials on OS were identified in ClinicalTrials.gov and the Lund University Libraries databases, and in the Swedish Medical Products Agency (MPA) and the European Medicines Agency (EMA) databases. In cases where the KM estimates were not available, data points from figures published in TLV's appraisals were extracted using the semi-automated tools Digitizelt and WebPlotDigitizer. The accuracy of survival extrapolations was assessed by comparing extrapolated and observed life-years (LYs), using three different measures: 1) difference in LYs between the treatment and control group; 2) LYs in the treatment group, 3) LYs in the control group.Results: We study TLV's preferred OS extrapolations and show that on average they overestimate the observed mean gain in LYs by 17%, and underestimate observed LYs by 5% and 1% in the treatment and control group, respectively.Conclusions: We conclude that it is feasible to validate OS extrapolations by comparing extrapolated and observed life-years. Even if survival extrapolations are reasonably accurate for the treatment and control group, respectively, this may still imply that extrapolations of LYs gained deviates to a larger extent. Follow-up studies on OS should be carried out to an increased extent to be able to validate, update and improve OS extrapolations in cost-effectiveness analysis of oncology drugs.

- Aims: A third of non-valvular atrial fibrillation (NVAF) patients are non-adherent to direct oral anticoagulants (DOACs). Estimates of the economic value of full adherence and the cost of two types of adherence improving interventions are important to healthcare planners and decision-makers.Methods: A cost-utility analysis estimated the impact of non-adherence over a 20-year horizon, for a patient cohort with a mean age of 77 years, based on data from the Stockholm Healthcare database of NVAF patients with incident stroke between 2011 and 2018. Adherence was defined using a medication possession ratio (MPR) cut-off of 90%; primary outcomes were the number of ischemic strokes and associated incremental cost–utility ratio.Results: Hypothetical comparisons between cohorts of 1,000 patients with varying non-adherence levels and full adherence (MPR >90%) predicted an additional number of strokes ranging from 117 (MPR = 81–90%) to 866 (MPR <60%), and years of life lost ranging from 177 (MPR = 81– 90%) to 1,318 (MPR < 60%; discounted at 3%). Chronic disease co-management intervention occurring during each DOAC prescription renewal and patient education intervention at DOAC initiation will be cost-saving to the health system if its cost is below SEK 143 and SEK 4,655, and cost-effective if below SEK 858 and SEK 28,665, respectively.Conclusion: Adherence improving interventions for NVAF patients on DOACs such as chronic disease co-management and patient education can be cost-saving and cost-effective, within a range of costs that appear reasonable to the Swedish healthcare system.

Tidskriftsartikel (refereegranskat)abstract
- Background and Aims: The ReFLeCT study demonstrated that switching to insulin degludec from other basal insulins was associated with reductions in glycated hemoglobin and hypoglycemic events in type 1 (T1D) and type 2 diabetes (T2D), and reductions in insulin doses in T1D. The aim of the present analysis was to assess the short- and long-term cost-effectiveness of switching to insulin degludec in Sweden.Methods: Short-term outcomes were evaluated over 1 year in a Microsoft Excel model, while long-term outcomes were projected over patient lifetimes using the IQVIA CORE Diabetes Model. Cohort characteristics and treatment effects were sourced from the ReFLeCT study. Costs (in 2018 Swedish krona [SEK]) encompassed direct medical expenditure and indirect costs from loss of workplace productivity. In the long-term analyses, patients were assumed to receive insulin degludec or continue prior insulin therapy (primarily insulin glargine U100) for 5 years, before all patients intensified to once-daily degludec and mealtime aspart.Results: Switching to insulin degludec was associated with improved quality-adjusted life expectancy of 0.04 and 0.02 quality-adjusted life years (QALYs) over 1 year, and 0.16 and 0.08 QALYs over patient lifetimes, in T1D and T2D. Combined costs in T1D and T2D were estimated to be SEK 1 249 lower and SEK 1 181 higher over the short term, and SEK 157 258 and SEK 2 114 lower over the long term. Benefits were due to lower insulin doses in T1D, reduced rates of hypoglycemia and lower incidences of diabetes-related complications. Insulin degludec was associated with an incremental cost-effectiveness ratio of SEK 64 298 per QALY gained for T2D over 1 year and considered dominant for T1D and T2D in all other comparisons.Conclusions: Insulin degludec was projected to be cost-effective or dominant versus other basal insulins for the treatment of T1D and T2D in Sweden.

Tidskriftsartikel (refereegranskat)abstract
- Objective The objective of this study was to assess the face validity of a disease model evaluating the cost-effectiveness of ataluren for the treatment of nonsense mutation Duchenne muscular dystrophy (nmDMD). Methods This was a Delphi panel study comprising of physicians with first-hand experience of ataluren for the treatment of nmDMD. Consensus was sought for previously unvalidated model data, including patient health status and quality of life measured using the Health Utility Index (HUI), mortality, informal caregiving, and the expected benefit of early ataluren treatment across four states: (1) ambulatory, (2) non-ambulatory, not yet requiring ventilation support, (3) non-ambulatory, night-time ventilation support, and (4) non-ambulatory, full-time ventilation support. Results Nine experts from five countries participated in the Delphi panel. Consensus was obtained for all questions after three panel rounds (except for two HUI-questions concerning hand function [dexterity]). Consensus HUI-derived utilities for state (1) were 1.0000 for ataluren on top of best supportive care (BSC) and 0.7337 for BSC alone. Corresponding estimates for state (2) were 0.3179 and 0.2672, for state (3) 0.1643 and 0.0913, and for state (4) -0.0732 and -0.1163. Consensus mortality rates for states (1), (2), and (3) were 4%, 13%, and 33%, and life expectancy in state (4) was agreed to be 3 years. Panelists further agreed that two informal caregivers typically provide day-to-day care/support to patients with nmDMD, and that starting treatment with ataluren at 2 versus 5 years of age would be expected to delay loss of ambulation by an additional 2 years, and initiation of night-time and full-time ventilation support by an additional 3 years, respectively. Limitations The main limitation concerns the size of the Delphi panel, govern primarily by the rarity of the disease. Conclusion This study confirms the face validity of key clinical parameters and assumptions underlying the ataluren cost-effectiveness model.

- Objectives: Systemic anaplastic large-cell lymphoma (sALCL) is a rare hematological malignancy with poor prognosis, which is associated with a significant economic burden. This study aimed to evaluate the cost-effectiveness of brentuximab vedotin (BV) in comparison to conventional chemotherapy in patients with relapsed/refractory sALCL, from a Chinese healthcare perspective.Methods: A partitioned survival model with three health states (progression-free survival, post-progression survival, and death) was adapted to compare BV against chemotherapy. Comparator represented a basket of commonly used chemotherapies in China. Two cohorts in each arm were estimated, representing patients receiving no transplant and autologous stem cell transplant (ASCT) after BV or chemotherapy. Clinical data was obtained from the pivotal phase-II trial (NCT00866047) for BV and also from the literature for a comparator. Resource use items covered drug acquisition and administration; concomitant medications; ASCT; treatment of adverse events; and long-term follow-up. Cost parameters were based on Chinese sources. Outcomes were measured in quality-adjusted life-years (QALYs). Both costs and effects were discounted at 5% according to Chinese guidelines. The impact of uncertainty was evaluated using deterministic and probabilistic sensitivity analyses.Results: The incremental cost-effectiveness ratio (ICER) for BV vs. chemotherapy was $9,610 (¥62,084) per QALY in the base case. The main model driver was superior progression-free and overall survival benefits of BV. The ICERs were relatively robust in the majority of sensitivity analyses, ranging around ±10% of the base case. Under the conventional decision thresholds (1–3 times of Chinese per capita GDP), the probability of BV being cost-effective ranged from 56 to 100%. Limitations of the study included the lack of comparative data from the trial and the small and heterogeneous sample due to its disease nature.Conclusions: BV may be a cost-effective treatment vs. chemotherapy in treating relapsed or refractory systemic anaplastic large-cell lymphoma in China.
