Cost-utility analysis of mogamulizumab in advanced mycosis fungoides and Sézary syndrome cutaneous T-cell lymphoma.

Aim: This study assessed the cost-utility of mogamulizumab, a novel monoclonal antibody, versus established clinical management (ECM) in UK patients in previously treated advanced mycosis fungoides (MF)/Sézary syndrome (SS). Materials & methods: Lifetime partitioned survival model based on overall survival, next treatment-free survival and the use of allogeneic stem cell transplant was developed. Inputs were from the pivotal MAVORIC trial, real-world evidence and published literature. Extensive sensitivity analyses were conducted. Results: Discounted incremental quality-adjusted life years (QALYs), costs and incremental cost-effectiveness ratio were 3.08, £86,998 and £28,233. Results were most sensitive to the survival extrapolations, utilities and costs after loss of disease control. Conclusion: Mogamulizumab is a cost-effective alternative to ECM in UK patients with previously treated advanced MF/SS.

Ceftaroline Fosamil for the Empiric Treatment of Hospitalized Adults with cSSTI: An Economic Analysis from the Perspective of the Spanish National Health System.

Purpose: Complicated skin and soft tissue infections (cSSTI) are associated with high healthcare resource use and costs. The emergency nature of cSSTI hospitalizations requires starting immediate empiric intravenous (IV) antibiotic treatment, making the appropriate choice of initial antibiotic therapy crucial. Patients and Methods: The use of ceftaroline fosamil (CFT) as an alternative to other IV antibiotic therapies for the empiric treatment of hospitalized adults with cSSTI (vancomycin, linezolid, daptomycin, cloxacillin, tedizolid) was evaluated through cost consequences analysis. The model structure was a decision tree accounting for four different pathways: patients demonstrating early response (ER) either discharged early (with oral antibiotic) or remaining in hospital to continue the initial therapy; non-responders either remaining on the initial IV therapy or switching to a second-line antibiotic. The model perspective was the Spanish National Health System. Results: CFT resulted in average percentage of patients discharged early (PDE) of 24.6% (CI 19.49-30.2%) with average total cost per patient of €6763 (€6268-€7219). Vancomycin, linezolid, daptomycin and tedizolid resulted in average PDE of 22% (17.34-27.09%), 26.4% (20.5-32.32%), 28.6% (22.08-35.79%) and 26.5% (20.39-33.25%), respectively, for a total cost per patient of €6,619 (€5,902-€6,929), €6,394 (€5,881-€6,904), €6,855 (€5,800-€7,410) and €7,173 (€6,608-€7,763), respectively. Key model drivers were ER and antibiotic treatment duration, with hospital costs accounting for over 83% of the total expenditures. Conclusion: Given its clinical and safety profile, CFT is an acceptable choice for cSSTI empiric therapy providing comparable ER and costs to other relevant antibiotic options.

Changes in treatment pattern and costs in advanced hepatocellular carcinoma (HCC).

INTRODUCTION: While essential for cost-effectiveness analyses, there are no current resource use and cost data available for advanced hepatocellular carcinoma (HCC) and selective internal radiation therapy (SIRT). The study aims to assess current resource use and costs in HCC and for SIRT compared to historical survey data. AREAS COVERED: To address this data gap, resource use was elicited via surveys and interviews with medical professionals experienced with HCC and SIRT in the United Kingdom. Unit costs were from publicly available databases. Resource use and costs were estimated and compared to prior surveys. EXPERT OPINION: From eleven responses, pre-progression costs for SIRT and systemic therapy were £256.77 and £292.27/month, respectively. One-off progression and post-progression costs were £209.98 and £522.84/month. Monthly costs were 54%-79% lower than in previous surveys, due to reduction in hospitalizations and funded social care. Furthermore, substantial differences in resource use associated with SIRT between clinical practice and clinical trials were found. In conclusion, increased availability and familiarity with systemic treatments has led to important changes in HCC care and SIRT administration. The uncertainty from the use of expert opinion and the limited number of hospitals with SIRT experience can be addressed with future research using large databases, registries.

Cost-utility analysis of selective internal radiation therapy with Y-90 resin microspheres in hepatocellular carcinoma.

Background: The study assessed the cost-utility of selective internal radiation therapy (SIRT) with Y-90 resin microspheres versus sorafenib in UK patients with unresectable hepatocellular carcinoma ineligible for transarterial chemoembolization. Materials & methods: A lifetime partitioned survival model was developed for patients with low tumor burden (≤25%) and good liver function (albumin-bilirubin grade 1). Efficacy, safety and quality of life data were from a European Phase III randomized controlled trial and published studies. Resource use was from registries and clinical surveys. Results: Discounted quality-adjusted life-years were 1.982 and 1.381, and discounted total costs were £29,143 and 30,927, for SIRT and sorafenib, respectively. Conclusion: SIRT has the potential to be a dominant (more efficacious/less costly) or cost-effective alternative to sorafenib in patients with unresectable hepatocellular carcinoma.

The economic burden of metastatic breast cancer in Spain.

Objectives: The study aimed to estimate the burden of metastatic breast cancer (mBC) in Spain over 5 years. Methods: An incidence-based cost-of-illness model was developed in which a cohort of patients with mBC was followed from the diagnosis of metastatic disease over 5 years or death. Resource use data were collected through a physician survey conducted with 10 clinical experts in Spain. The model distinguished patients according to HER2 and hormonal receptor (HR) status, and followed the patient cohort in monthly cycles. Results: The incident cohort was estimated to be 2,923 patients with mBC, consisting of 1,575 HER2-/HR+, 520 HER2+/HR+, 324 HER2+/HR-, and 503 triple negative patients. The estimated mean survival over the 5-year time period was 2.51 years, on average, with longer survival of 3.36 years for HER2+/HR+, 2.41 years for HER2-/HR+, 2.82 years for HER2+/HR- and shortest mean survival of 1.74 years for triple negative patients. The total costs were €469,92,731 for the overall population, €190,079,787 for the HER2-/HR+, €151,045,260 for the HER2+/HR+, €80,827,171 for the HER2+/HR- and €47,540,512 for the triple negative subgroups over 5 years. Per patient total costs were €160,642 on average, €120,664 for HER2-/HR+, €290,346 for HER2+/HR+, €249,152 for HER2+/HR-and €94,572 for triple negative patients over 5 years. Conclusions: The economic burden of mBC in Spain is significant, but differs by HER2 and HR status. HER2-/HR +patients account for the highest burden due to the prevalence of this category, but HER2+/HR +patients have the highest per patient costs.

Economic analysis of ceftaroline fosamil for treating community-acquired pneumonia in Spain.

Background: Adults admitted to hospital with community-acquired pneumonia (CAP) impose significant burden upon limited hospital resources. To achieve early response and possibly early discharge, thus reducing hospital expenditure, the choice of initial antibiotic therapy is pivotal.Methods: A cost-consequences model was developed to evaluate ceftaroline fosamil (CFT) as an alternative to other antibiotic therapies (ceftriaxone, co-amoxiclav, moxifloxacin, levofloxacin) for the empiric treatment of hospitalized adults with moderate/severe CAP (PORT score III-IV) from the perspective of the Spanish National Health System (NHS).Findings: Compared with ceftriaxone, the model predicted an increase in the number of CFT-treated patients discharged early (PDE) (30.6% vs. 26.1%) while decreasing initial antibiotic failures (3.8% vs. 7.6%). For patients with pneumococcal pneumonia, CFT was cost-saving vs. ceftriaxone (by 1.2%) and significantly increased PDE (32.1% vs. 24.6%). CFT resulted in cost-saving vs. levofloxacin, due lower initial antibiotic therapy costs and increased PDE (30.6% vs. 14.9%). Moxifloxacin and co-amoxiclav early response rate of 53.63% and 54.24% resulted in cost neutrality vs. CFT, with direct comparison hampered by the significantly different early response criteria utilized in the literature.Conclusions: Despite a higher unit cost, CFT is a reasonable alternative to other agents for adults hospitalized with moderate/severe CAP, given the projected higher PDE achieved with similar or lower total costs.

A cost-consequence analysis of parecoxib and opioids vs opioids alone for postoperative pain: Chinese perspective.

PURPOSE: The use of parecoxib plus opioids for postoperative analgesia in noncardiac surgical patients seems to be cost-saving in Europe due to a reduction in opioid use and opioid-related adverse events. Given the lack of information on postoperative analgesic use in Asia, this study assessed the economic consequences of the addition of parecoxib to opioids vs opioids alone to treat postsurgical pain in China. METHODS: A cost-consequence economic evaluation assessed direct medical costs related to opioid-related clinically meaningful events (CMEs) utilizing dosing information and reported frequency of events from a Phase III, randomized, double-blind, global clinical trial (PARA-0505-069) of parecoxib plus opioids vs opioids alone for 3 days following major orthopedic, abdominal, gynecologic, or noncardiac thoracic surgery requiring general or regional anesthesia. The cost of CMEs was calculated using information on resource utilization and unit costs provided by a panel of clinical experts in China. Sensitivity analyses were performed to test the robustness of the results. RESULTS: Patients treated with parecoxib plus opioids reported fewer CMEs (mean 0.62 vs 1.04 events per patient [P<0.0001]) compared with opioids alone for the 3-day postoperative period. This suggested a potential savings of 356 Chinese yuan (¥) per patient over the 3 days (total cost of ¥1,418 for parecoxib plus opioids vs ¥1,774 with opioid use alone). CONCLUSION: Fewer CMEs with parecoxib plus opioids suggest a reduction in medical resource utilization and reduced costs compared to opioids alone when modeling analgesic use in non-cardiac surgery patients in China.

Budget impact analysis of botulinum toxin A therapy for upper limb spasticity in the United Kingdom.

BACKGROUND: Botulinum toxin A (BoNT-A) is an effective treatment for patients with upper limb spasticity (ULS), which is a debilitating feature of upper motor neuron lesions. BoNT-A preparations available in the UK are associated with different costs. METHODS: We developed a budget impact model to assess the effect of changing market shares of different BoNT-A formulations - abobotulinumtoxinA, onabotulinumtoxinA, and incobotulinumtoxinA - and best supportive care, from the UK payer perspective, over a 5-year time horizon. Epidemiological and resource use data were derived from published literature and clinical expert opinion. One-way sensitivity analyses were performed to determine parameters most influential on budget impact. RESULTS: Base-case assumptions showed that an increased uptake of abobotulinumtoxinA resulted in a 5-year savings of £6,283,829. Treatment with BoNT-A costs less than best supportive care per patient per year, although treating a patient with onabotulinumtoxinA (£20,861) and incobotulinumtoxinA (£20,717) cost more per patient annually than with abobotulinumtoxinA (£19,800). Sensitivity analyses showed that the most influential parameters on budget were percentage of cerebral palsy and stroke patients developing ULS, and the prevalence of stroke. CONCLUSION: Study findings suggest that increased use of abobotulinumtoxinA for ULS in the UK could potentially reduce total ULS cost for the health system and society.

Attempt to increase the transparency of fourth hurdle implementation in Central-Eastern European middle income countries: publication of the critical appraisal methodology.

BACKGROUND: In middle income countries the number of trained health technology assessment specialists is limited and the public budget for health technology assessment is considerably lower compared to developed countries. These countries therefore must develop their own solutions to improve the quality and efficiency of health technology assessment implementation in reimbursement decisions. Our study aimed to develop a scientifically rigorous and detailed appraisal checklist for economic evaluations of pharmaceuticals in the single health technology assessment process. METHODS: The research design entailed a review of economic evaluations, submitted for reimbursement of pharmaceuticals, by two independent academic reviewers to identify the most common methodological problems. Fifty economic evaluations submitted in 2007-2008, randomly selected by the Health Technology Assessment Office served as data sources. The new checklist was developed by an iterative working process: first by assessing ten economic evaluations, then improving the checklist by generating new question items, then employing the improved checklist to assess the next ten economic evaluations. After appraising 25 documents, the reviewers reconciled their opinions and improved the checklist with the researchers of the Health Technology Assessment Office during an expert panel discussion. The reviewers scrutinized the second 25 economic evaluations, after which the expert panel finalized the checklist with consensus. RESULTS: The final checklist consists of 91 yes or no questions in 11 main topics concerning comparator selection, efficacy, effectiveness, costs, sensitivity analysis, methodological approach, transparency, and interpretation of results. The new checklist is based on current Hungarian evaluation practice. As the published checklist will be part of the official single health technology assessment process of pharmaceuticals, submitters will be able to assure the quality of their economic evaluation. CONCLUSIONS: The transparent critical appraisal method should improve the consistency of pharmaceutical reimbursement decisions and facilitate the utilization of economic evaluations in other fields of health care decision-making in other Central-Eastern European countries.

Economic evaluation of new targeted therapies for the first-line treatment of patients with metastatic renal cell carcinoma.

OBJECTIVE: • To assess the economic value of targeted therapies as first-line metastatic renal cell carcinoma (mRCC) treatment in the US and Sweden by indirect comparison of survival data. METHODS: • A Markov model simulated disease progression, adverse events and survival with sunitinib vs sorafenib in the US and bevacizumab plus interferon-α (IFN-α) in both countries. • Results, in life-years (LYs), progression-free LYs (PFLYs), quality-adjusted LYs (QALYs) gained and treatment costs (2008 USD) were obtained through deterministic and probabilistic analyses over the patient's lifetime. RESULTS: • Sunitinib was more effective and less costly than sorafenib (gains of 0.52 PFLYs, 0.16 LYs and 0.17 QALYs and savings/patient of $13,576 in the US) and bevacizumab plus IFN-α (gains of 0.19 PFLYs, 0.23 LYs and 0.16 QALYs in both countries and savings/patient of $67,798 and $47,264 in the US and Sweden, respectively). • Results were most influenced by hazard ratios for progression-free and overall survival and treatment costs, making results generalizable across other countries if relative costs were to fall within the ranges of those in the US and Sweden. CONCLUSION: • The present analyses suggest that first-line mRCC treatment with sunitinib is a cost-effective alternative to sorafenib and bevacizumab plus IFN-α.

Cost-effectiveness of the Endeavor stent in de novo native coronary artery lesions updated with contemporary data.

AIMS: The Endeavor zotarolimus-eluting coronary stent has been shown to reduce the restenosis rate compared to bare metal stents and has impacted other clinical measures such as mortality, acute myocardial infarctions (AMI) and target vessel revascularisation (TVR). METHODS AND RESULTS: Using pooled efficacy data from the Endeavor clinical trial programme, a model was developed to compare the cost effectiveness of the Endeavor drug eluting stent (DES) with the Driver bare meal stent (BMS) over a four year time period. Endeavor was more costly but had an improved clinical outcome compared to Driver BMS over four years with a 4% reduction in deaths, 33% reduction in AMI and a 45% reduction in TVR. Late stent thrombosis was the only event showing an increased incidence for Endeavor of 0.2% compared to 0% for Driver. The incremental cost effectiveness ratio was pound3,757/quality adjusted life years (QALY). CONCLUSIONS: Although much controversy has surrounded the appropriate way to assess the cost effectiveness of DES technology, a comprehensive analysis is presented and this suggests that by using extended clinical trial data out to four years, the Endeavor DES in particular, but DES technologies in general, are cost-effective approaches to percutaneous coronary intervention.

Economic evaluation of sunitinib malate for the first-line treatment of metastatic renal cell carcinoma.

PURPOSE: To assess the cost effectiveness and cost utility of sunitinib malate as a first-line treatment in metastatic renal cell carcinoma (mRCC) compared with interferon-alfa (IFN-alpha) and interleukin-2 (IL-2) from a US societal perspective. METHODS: A Markov model was developed to simulate disease progression and to determine progression-free survival, total life-years (LYs), and quality-adjusted life-years (QALYs) gained. Model parameters were derived from the pivotal trial of sunitinib, published literature, government sources, and clinical experts' opinions. The model included trial-based adverse events (AEs). Costs of drug treatment, routine follow-up, AEs, disease progression, and best supportive care (BSC) of terminally ill patients were included. Results were tested using probabilistic and deterministic sensitivity analyses. RESULTS: Treatment with sunitinib is associated with a gain in progression-free years of 0.41 and 0.35 over IFN-alpha and IL-2. The estimated gains over IFN-alpha were 0.11 LYs and 0.14 QALYs, and over IL-2 were 0.24 LYs and 0.20 QALYs. Both IFN-alpha and sunitinib treatments dominate IL-2 treatment; the incremental cost-effectiveness ratio of sunitinib versus IFN-alpha was $18,611 per progression-free year gained and $67,215 per LY gained, and the cost-utility ratio is $52,593 per QALY gained (at a 5% discount rate). Sensitivity analyses found the results to be most sensitive to utility values during treatment, the cost of sunitinib, and the cost of BSC. Model results were robust to changes in other model variables. CONCLUSION: These results suggest that sunitinib is a cost-effective alternative to IFN-alpha as a first-line treatment for mRCC.

Evaluation of health status in epilepsy using the EQ-5D questionnaire: a prospective, observational, 6-month study of adjunctive therapy with anti-epileptic drugs.

AIMS: The aims of this project were to evaluate the impact of adjunctive treatment with an anti-epileptic drug (AED) on the health status of people with epilepsy and to investigate how seizure frequency affects their health status. METHODS: Adult epilepsy patients, refractory to current treatment, were included in this prospective observational study. Patients commencing adjunctive therapy with one of five AEDs (topiramate, lamotrigine, gabapentin, clobazam, vigabatrin) were eligible for inclusion. The study took place at the outpatient clinics of the National Hospital for Neurology and Neurosurgery, Queen Square, London. Patients completed the EQ-5D, a generic health status measure, at baseline and again after 3 and 6 months. Information was also collected on medications and seizure frequency. RESULTS: In total, 125 patients entered the study and were followed up for 6 months. Patients treated with topiramate had a significant increase (p < 0.05) in EQ-5D score from baseline, indicating an improvement in their health status whereas scores for lamotrigine, clobazam and gabapentin all showed a non-significant decline. When the data were analysed according to seizure frequency, only patients who became seizure-free on adjunctive treatment had a significant increase in their health status. The group who had a 50% reduction in seizure frequency did not have increased health status. CONCLUSIONS: In summary, adjunctive treatment with topiramate significantly increased health status as measured by the EQ-5D. These data also suggest that achievement of seizure-freedom is the key to improving health status in this patient group.
