Cost-effectiveness of overactive bladder treatments: from the US payer perspective.

AIM: To assess the cost-effectiveness of onabotulinumtoxinA (onabotA), implantable sacral nerve stimulation devices, percutaneous tibial nerve stimulation, anticholinergic medications and mirabegron compared with best supportive care (BSC) for management of refractory overactive bladder (OAB). METHODS: A Markov model was developed to compare the cost-effectiveness of treatment options with BSC over a 10-year time horizon. Resource utilization, discontinuation rates and costs were derived from unpublished and published sources. Quality-adjusted life-years (QALYs) and incremental cost-effectiveness ratios were reported. RESULTS: Treatment with onabotA 100U produced the largest gain in QALYs (7.179) and lowest estimated incremental cost-effectiveness ratio ($32,680/QALY) of all assessed treatments compared with BSC. CONCLUSION: Compared with BSC, onabotA 100U was the most cost-effective treatment option for patients with refractory OAB.

OnabotulinumtoxinA in the treatment of overactive bladder: a cost-effectiveness analysis versus best supportive care in England and Wales.

The cost-effectiveness of onabotulinumtoxinA (BOTOX(®)) 100 U + best supportive care (BSC) was compared with BSC alone in the management of idiopathic overactive bladder in adult patients who are not adequately managed with anticholinergics. BSC included incontinence pads and, for a proportion of patients, anticholinergics and/or occasional clean intermittent catheterisation. A five-state Markov model was used to estimate total costs and outcomes over a 10-year period. The cohort was based on data from two placebo-controlled trials and a long-term extension study of onabotulinumtoxinA. After discontinuation of initial treatment, a proportion of patients progressed to downstream sacral nerve stimulation (SNS). Cost and resource use was estimated from a National Health Service perspective in England and Wales using relevant reference sources for 2012 or 2013. Results showed that onabotulinumtoxinA was associated with lower costs and greater health benefits than BSC in the base case, with probabilistic sensitivity analysis indicating an 89 % probability that the incremental cost-effectiveness ratio would fall below £20,000. OnabotulinumtoxinA remained dominant over BSC in all but two scenarios tested; it was also economically dominant when compared directly with SNS therapy. In conclusion, onabotulinumtoxinA appears to be a cost-effective treatment for overactive bladder compared with BSC alone.

Cost-effectiveness analysis of onabotulinumtoxinA (BOTOX(®)) for the management of urinary incontinence in adults with neurogenic detrusor overactivity: a UK perspective.

OBJECTIVES: To evaluate the cost effectiveness of onabotulinumtoxinA (BOTOX(®), 200 units [200 U]) for the management of urinary incontinence (UI) in adults with neurogenic detrusor overactivity (NDO) due to subcervical spinal cord injury or multiple sclerosis that is not adequately managed with anticholinergic drugs (ACHDs). PERSPECTIVE: UK National Health Service (NHS) perspective. METHODS: A Markov state-transition model was developed, which compared onabotulinumtoxinA + best supportive care (BSC) with BSC alone (comprising behavioural therapy and pads, alone or in combination with clean intermittent catheterization and possibly with ACHDs). Non-responders were eligible for invasive procedures. Health states were defined according to the reduction in UI episodes. Efficacy data and estimates of resource utilization were pooled from 468 patients on onabotulinumtoxinA in two phase III clinical trials. Drug costs (2013) and administration costs (NHS Reference Costs 2011-2012) were obtained from published sources. The time horizon of the model was 5 years, and costs and benefits were discounted at 3.5%. Scenario, one-way and probabilistic sensitivity analyses (PSAs) were conducted to explore uncertainties around the assumptions. RESULTS: In the base case, treatment with onabotulinumtoxinA + BSC over 5 years was associated with an increase in costs of £1,689 and an increase in quality-adjusted life-years (QALYs) of 0.4, compared with BSC alone, resulting in an incremental cost-effectiveness ratio of £3,850 per QALY gained. Sensitivity analyses showed that utility values had the greatest influence on model results. PSA suggests that onabotulinumtoxinA + BSC had a 100 % probability of being cost effective at a willingness to pay of <£20,000. CONCLUSION: For adult patients with NDO who are not adequately managed with ACHDs, onabotulinumtoxinA + BSC appears to be a cost-effective use of resources in the UK NHS.

Is testosterone replacement therapy in males with hypogonadism cost-effective? An analysis in Sweden.

INTRODUCTION: Testosterone replacement therapy (TRT) has been recommended for the treatment of primary and secondary hypogonadism. However, long-term implications of TRT have not been investigated extensively. AIM: The aim of this analysis was to evaluate health outcomes and costs associated with life-long TRT in patients suffering from Klinefelter syndrome and late-onset hypogonadism (LOH). METHODS: A Markov model was developed to assess cost-effectiveness of testosterone undecanoate (TU) depot injection treatment compared with no treatment. Health outcomes and associated costs were modeled in monthly cycles per patient individually along a lifetime horizon. Modeled health outcomes included development of type 2 diabetes, depression, cardiovascular and cerebrovascular complications, and fractures. Analysis was performed for the Swedish health-care setting from health-care payer's and societal perspective. One-way sensitivity analyses evaluated the robustness of results. MAIN OUTCOME MEASURES: The main outcome measures were quality-adjusted life-years (QALYs) and total cost in TU depot injection treatment and no treatment cohorts. In addition, outcomes were also expressed as incremental cost per QALY gained for TU depot injection therapy compared with no treatment (incremental cost-effectiveness ratio [ICER]). RESULTS: TU depot injection compared to no-treatment yielded a gain of 1.67 QALYs at an incremental cost of 28,176 EUR (37,192 USD) in the Klinefelter population. The ICER was 16,884 EUR (22,287 USD) per QALY gained. Outcomes in LOH population estimated benefits of TRT at 19,719 EUR (26,029 USD) per QALY gained. Results showed to be considerably robust when tested in sensitivity analyses. Variation of relative risk to develop type 2 diabetes had the highest impact on long-term outcomes in both patient groups. CONCLUSION: This analysis suggests that lifelong TU depot injection therapy of patients with hypogonadism is a cost-effective treatment in Sweden. Hence, it can support clinicians in decision making when considering appropriate treatment strategies for patients with testosterone deficiency.

Societal savings in patients with advanced non-squamous non-small-cell lung cancer receiving bevacizumab-based versus non-bevacizumab-based treatments in France, Germany, Italy, and Spain.

BACKGROUND: The purpose of this study was to investigate the savings accrued using bevacizumab-based treatment for non-small-cell lung cancer from the societal perspective, taking only public costs into account, in France, Germany, Italy, and Spain. METHODS: Societal costs were estimated by collecting and analyzing labor costs, carer costs, sickness benefits, disability benefits, and home care benefits. Cost inputs were derived from publicly available databases or from the published literature. Expert opinion was only used if no other source was available. Efficacy data from two randomized clinical trials were used. The time horizon in the health economic model was lifetime. Efficacy and costs were discounted by 3.5%. All main model parameters were tested in deterministic and probabilistic sensitivity analyses. RESULTS: Mean incremental savings to society per patient ranged from €2277 in Italy to €4461 in Germany. The results were most sensitive to the change in proportion of patients working fulltime and the proportion of patients who were able to return to work. CONCLUSION: This analysis shows that bevacizumab-based treatment in non-small-cell lung cancer is associated with more savings to society compared to standard chemotherapy in terms of increased productivity and decreased social benefits paid to patients who are able to work in France, Germany, Italy, and Spain.

Physical and stress-strain properties of wheat (Triticum aestivum) kernel.

BACKGROUND: Two hard wheat varieties and one soft variety grown under the same agroecological conditions were analyzed for their physical and uniaxial stress-strain compression properties. RESULTS: The physical properties of wheat kernel were determined at a moisture content of 0.13 kg kg(-1) (wet basis), whereas the stress-strain compression test was conducted at a kernel moisture content from 0.082 to 0.433 kg kg(-1) . Mean kernel lengths were 5.46 (5.37 and 5.38) mm, widths were 2.56 (2.47 and 2.62) mm and thicknesses were 2.12 (2.18 and 2.43) mm for Simonida, Dragana and NS 40S cultivars, respectively. Bulk densities were 791.34 (Simonida), 788.51 (Dragana) and 731.77 kg m(-3) (NS 40S). The force at the yield point was 241.46 N for Dragana (moisture content 0.133 kg kg(-1) ), 244.30 N for Simonida (0.136 kg kg(-1) ) and 164.90 N for NS 40S (0.433 kg kg(-1) ). CONCLUSION: The width and thickness of the analyzed kernels were small compared with the length, and bulk densities were also moderate. The yield point force values of the two hard varieties were 2.2 times higher than the values of the soft variety, at a moisture content of 0.136 kg kg(-1) for Simonida, 0.133 kg kg(-1) for Dragana and 0.141 kg kg(-1) for NS 40S.

Prolonged prophylaxis with valganciclovir is cost effective in reducing posttransplant cytomegalovirus disease within the United States.

BACKGROUND: Cytomegalovirus (CMV) disease in transplant patients is known to have a substantial clinical and economic burden, and its prevention is expected to have long-term benefits. Evidence from the Improved Protection Against CMV in Transplant trial proved that prolonged prophylaxis of 200 days with valganciclovir compared with 100 days significantly reduces the incidence of CMV in high-risk kidney transplant seropositive donors/seronegative recipients. The aim of this study was to develop a cost-effectiveness model to evaluate prolonged prophylaxis of 200 days with valganciclovir and its long-term economic impact. METHODS: An economic model was designed to simulate long-term costs and outcomes of prolonged prophylaxis with valganciclovir (200 vs. 100 days) in a cohort of 10,000 high-risk renal transplant patients over 5 and 10 years. The first year of the model was based on the results of the Improved Protection Against CMV in Transplant trial and the extension to the long-term periods (5 and 10 years); and quality of life data were based on evidence retrieved through a systematic literature search. This analysis was conducted from the US healthcare payer perspective. RESULTS: For the 5-year time horizon, the incremental cost-effectiveness ratio of US $14,859/quality-adjusted life year (QALY) suggests that 200-day valganciclovir prophylaxis is cost effective over the 100-day regimen considering a threshold of US $50,000/QALY. The 10-year analysis revealed the 200-day prophylaxis as cost saving with a 2380 QALY gain and simultaneously lower cost. CONCLUSION: Prolonged prophylaxis with valganciclovir reduces the incidence of events associated with CMV infection in high-risk kidney transplant recipients and is a cost-effective strategy in CMV disease management.

Societal cost savings through bevacizumab-based treatment in non-small cell lung cancer (NSCLC).

Bevacizumab in combination with platinum-based chemotherapy is associated with increased survival outcomes compared to chemotherapy alone in patients with non-squamous metastatic non-small cell lung cancer (mNSCLC). The objective of this study was to estimate potential economic benefits from a societal perspective in patients returning to work when treated with bevacizumab-based combination therapy. These economic benefits were assessed with respect to reduced productivity losses and described in terms of per patient cost savings. The analysis was conducted for France, Germany, Italy and Spain. Clinical outcomes in terms of progression-free survival (PFS) were based on two phase III clinical trials (E4599 and AVAiL) comparing bevacizumab + chemotherapy vs. chemotherapy alone. Potential cost savings due to reduction in productivity losses were assessed in progression-free patients who return back to work (human capital approach). It was assumed that 20% of all progression-free patients with performance status 0 or 1 and below 55 years of age would return back to work after the induction therapy maintaining their prior employment status (60% part-time, 40% full-time). Savings were calculated over 1 and 1.5 year time horizons. Mean savings, per progression-free patient ranged from 12,401 euro in Spain at year 1 to 39,001 euro in France at year 1.5. Respective findings proved to be fairly sensitive to the change of employment patterns and labour costs. This analysis shows that bevacizumab-based treatment can result in substantial cost savings in progression-free patients with mNSCLC.
