Cost-consequence of abatacept as first-line therapy in Japanese rheumatoid arthritis patients using IORRA real-world data.

OBJECTIVES: To investigate the cost-effectiveness of abatacept (ABA) as first-line (1L) therapy in Japanese rheumatoid arthritis (RA) patients using data from the Institute of Rheumatology, Rheumatoid Arthritis database. METHODS: A decision-analytic model was used to estimate the cost per American College of Rheumatology response of at least 50% improvement (ACR50) responder and per patient in Clinical Disease Activity Index (CDAI) and Simplified Disease Activity Index (SDAI) remission from a Japanese healthcare payers' perspective over a 2-year time horizon. Clinical characteristics of patients on ABA-1L were matched with those of patients on ABA second or later line (2L+) or tumour necrosis factor inhibitor (TNFi)-1L directly or using propensity scores. Resource utilisation and medical costs were calculated from the Japan Medical Data Center claims database. Parameter uncertainty was addressed by sensitivity and subgroup analyses (age, treatment duration, Japanese version of Health Assessment Questionnaire [J-HAQ] score). RESULTS: Incremental costs per member per month (ΔPMPM) for ABA-1L versus TNFi-1L and ABA-2L+ were -1,571 Japanese Yen (JPY) and 81 JPY, respectively. For ABA-1L versus TNFi-1L, ΔPMPM by ACR50 response was -11,715 JPY and by CDAI and SDAI remission 11,602 JPY and 47,003 JPY, respectively. Corresponding costs for ABA-1L were lower for all outcome parameters versus those for ABA-2L+. Scenario analyses showed that ABA-1L was cost-effective over TNFi-1L in patients <65 years for any outcome. Furthermore, ABA-1L was cost-effective over ABA-2L+ for all outcomes in patients with age <65 years, disease duration <5 years and J-HAQ ≥1.5. CONCLUSIONS: ABA-1L demonstrated a favourable cost-effectiveness profile in RA patients, accruing savings for the Japanese healthcare payers.

Cost-effectiveness analysis of NEPA, a fixed-dose combination of netupitant and palonosetron, for the prevention of highly emetogenic chemotherapy-induced nausea and vomiting: an international perspective.

PURPOSE: The aim of this study was to assess the cost-effectiveness of NEPA, a fixed-dose combination of oral netupitant (300 mg) and palonosetron (0.5 mg), compared to available treatments in Spain after aprepitant generic introduction in the market, and to discuss results in previously performed analyses in different wordwide settings. METHODS: A Markov model including three health states, complete protection, complete response at best and incomplete response, was used to evaluate the cost-effectiveness of NEPA versus common treatment options in Spain during 5 days after chemotherapy. Incremental costs including treatment costs and treatment failure management cost as well as incremental effects including quality adjusted life days (QALDs) and emesis-free days were compared between NEPA and the comparator arms. The primary outcomes were cost per avoided emetic event and cost per QALDs gained. RESULTS: NEPA was dominant (more effective and less costly) against aprepitant combined with palonosetron, and fosaprepitant combined with granisetron, while, compared to generic aprepitant plus ondansetron, NEPA showed an incremental cost per avoided emetic event of €33 and cost per QALD gained of €125. CONCLUSION: By most evaluations, NEPA is a dominant or cost-effective treatment alternative to current antiemetic standards of care in Spain during the first 5 days of chemotherapy treatment in cancer patients, despite the introduction of generics. These results are in line with previously reported analyses throughout different international settings.

The role of income in brain tumor patients: a descriptive register-based study : No correlation between patients' income and development of brain cancer.

Socioeconomic status (SES) and its association with cancer in general have been thoroughly studied in the last decades. Several studies have shown associations between SES and many types of cancer such as lung cancer, breast cancer, and prostate cancer. For gliomas, no clear occupational or exposure risk factors have been identified, although some possible risk factors such as use of cellular telephone are still controversial. The aim in the present study is to analyze whether there is an association between SES and development of brain cancer. Data from 1999 through 2013 were collected from the Swedish Cancer Registry and from the National Statistics of Sweden. Age-standardized incidence rates for people with different income were calculated using linear regression model. A total of 11,892 patients were included, of which 5675 were meningiomas, 1216 low-grade gliomas, and 5001 high-grade gliomas. No clear trend between increasing incidence rates and higher income was seen in neither of the investigated brain tumor histologies. In conclusion, the results should be interpreted with caution, but there does not seem to be a correlation in this material between increased income and development of brain cancer.

A rotating-slit-collimator-based gamma radiation mapper.

For situations with radioactive material out of control where it may be physically difficult or prohibited to access areas close to the source, measurements from distance may be the only way to assess the radiation environment. Using collimated detectors will provide means to locate the direction of the radiation from the source. To investigate the possibilities of mapping gamma emitting radioactive material in a closed non-enterable area, a tentative system for mapping radioactive materials from a distance was built. The system used a computer controlled cylindrical rotating slit collimator with a high purity germanium detector placed in the cylinder. The system could be placed on a car-towed trailer, with the centre of the detector about 1.4 m above ground. Mapping was accomplished by the use of a specially developed image reconstruction algorithm that requires measurements from two or more locations around the area to be investigated. The imaging capability of the system was tested by mapping an area, 25 by 25 m2, containing three 330 MBq 137Cs point sources. Using four locations outside the area with about 20 min measuring time in each location and applying the image reconstruction algorithm on the deconvoluted data, the system indicated the three source locations with an uncertainty of 1-3 m. The results demonstrated the potential of using collimated mobile gamma radiometry combined with image reconstruction to localize gamma sources inside non-accessible areas.

Aflibercept vs. Ranibizumab: cost-effectiveness of treatment for wet age-related macular degeneration in Sweden.

PURPOSE: Monthly dosing with ranibizumab (RBZ) is needed to achieve maximal visual gains in patients with neovascular ('wet') age-related macular degeneration (wAMD). In Sweden, dosing is performed as needed (RBZ PRN), resulting in suboptimal efficacy. Intravitreal aflibercept (IVT-AFL) every 2 months after three initial monthly doses was clinically equivalent to RBZ monthly dosing (RBZ q4) in wAMD clinical trials. We assessed the cost-effectiveness of IVT-AFL versus RBZ q4 and RBZ PRN in Sweden. METHODS: A Markov model compared IVT-AFL to RBZ q4 or RBZ PRN over 2 years. Health states were based on visual acuity in better-seeing eye; a proportion discontinued treatment monthly or upon visual acuity <20/400. Parameters were estimated from trial data, published literature or expert opinion. Analyses were performed from a societal perspective with a lifetime horizon. The model calculated costs, quality-adjusted life years (QALYs) and incremental cost-effectiveness ratios (ICERs), discounted 3% annually. Deterministic and probabilistic sensitivity analyses were performed. RESULTS: Lifetime cost of IVT-AFL was 578 400 SEK, compared with 565 700 SEK for RBZ PRN and 686 600 SEK for RBZ q4. Compared with RBZ PRN, the ICER of IVT-AFL was 27 000 SEK/QALY gained. RBZ q4 cost 20.4 million SEK/QALY gained versus IVT-AFL. Results were sensitive to IVT-AFL efficacy, but IVT-AFL had a 100% probability of being cost-effective versus both RBZ PRN and RBZ q4 at a willingness-to-pay threshold of 500 000 SEK. CONCLUSION: Results suggest, in Sweden, at parity price level, IVT-AFL is less costly than RBZ q4, while demonstrating similar efficacy; IVT-AFL is cost-effective versus RBZ PRN.

A Cost-Effectiveness Analysis of Minimally Invasive versus Open Surgery Techniques for Lumbar Spinal Fusion in Italy and the United Kingdom.

OBJECTIVE: Evaluate the cost-effectiveness of minimally invasive surgery (MIS) compared with open surgery (OS) techniques for one- or two-level lumbar spinal fusion in the treatment of degenerative lumbar spinal conditions in the United Kingdom and Italy. METHODS: A health economic model was developed on the basis of results from a systematic literature review and meta-analysis to determine the cost-effectiveness of MIS compared with OS for lumbar spinal fusion. The analysis was conducted from a health care payer perspective. Parameters included in the model were surgery, blood loss, duration of hospitalization, postoperative complications, and health-related quality of life (HRQOL). Cost-effectiveness was determined by the incremental cost per quality-adjusted life-year gained. RESULTS: MIS was the dominant strategy compared with OS (i.e., yielding both cost savings and improved HRQOL). Cost savings were driven mainly by shorter length of hospital stay, reduced blood loss, and fewer complications such as surgical site infection. The total cost saving per procedure was €973 for Italy and €1666 for the United Kingdom, with an improvement of 0.04 quality-adjusted life-year over 2 years in HRQOL. One-way sensitivity analyses and predefined scenario(s) analyses confirmed the robustness of the model. CONCLUSIONS: MIS is a less expensive and a more effective treatment compared with OS for spinal lumbar fusion in both Italy and the United Kingdom. Lower downstream costs and increased HRQOL in the MIS group compensate for potential higher upfront costs of MIS implants and surgery equipment.

Burden of herpes zoster and post-herpetic neuralgia in Sweden.

BACKGROUND: The societal economic burden of herpes zoster in Sweden is not well described today. This study is a top-down analysis of Swedish registers with the objective to describe the burden of herpes zoster and post-herpetic neuralgia in Sweden during 2011. METHODS: Data for inpatient care; outpatient primary and specialized cares; the prescriptions of drugs, sick leave and the number or diagnostic tests were collected from Swedish national databases. The incidence of the disease was estimated based on the number of prescriptions of antiviral drugs. RESULTS: The incidence of herpes zoster was estimated to 315 and 577 cases per 100,000 people for patients at all ages and > = 50 years, respectively. Almost 30,000 patients at all ages were diagnosed with herpes zoster and the societal cost to treat these patients, including the cost to treat those patients who later developed post-herpetic neuralgia, added up to nearly 227 MSEK (31.6 M€) which corresponds to 7,600 SEK (€870) per patient. The main contributors to the total cost for the treatment of HZ patients were primary care (43 %); sick leave (28 %); hospitalization (10 %) and specialist care (7 %). Medication was a relatively small contributor with 8.5 MSEK (4 %; 1.0 M€) to the overall costs for patients at all ages. The corresponding total cost including only patients 50 years and older was 168 MSEK (19.2 M€) or 8,200 SEK (€939) per patient. CONCLUSIONS: The current study demonstrates that the burden of herpes zoster is significant in Sweden. The society, the health care payers and the patients potentially have a lot to gain by introducing a vaccination program to patients 50 years and older and as a consequence reduce the economic and clinical burden of herpes zoster and post-herpetic neuralgia.

Cost-effectiveness of dronedarone and standard of care compared with standard of care alone: US results of an ATHENA lifetime model.

BACKGROUND: The first antiarrhythmic drug to demonstrate a reduced rate of cardiovascular hospitalization in atrial fibrillation/flutter (AF/AFL) patients was dronedarone in a placebo-controlled, double-blind, parallel arm Trial to assess the efficacy of dronedarone 400 mg bid for the prevention of cardiovascular Hospitalization or death from any cause in patiENts with Atrial fibrillation/atrial flutter (ATHENA trial). The potential cost-effectiveness of dronedarone in this patient population has not been reported in a US context. This study assesses the cost-effectiveness of dronedarone from a US health care payers' perspective. METHODS AND RESULTS: ATHENA patient data were applied to a patient-level health state transition model. Probabilities of health state transitions were derived from ATHENA and published data. Associated costs used in the model (2010 values) were obtained from published sources when trial data were not available. The base-case model assumed that patients were treated with dronedarone for the duration of ATHENA (mean 21 months) and were followed over a lifetime. Cost-effectiveness, from the payers' perspective, was determined using a Monte Carlo microsimulation (1 million fictitious patients). Dronedarone plus standard care provided 0.13 life years gained (LYG), and 0.11 quality-adjusted life years (QALYs), over standard care alone; cost/QALY was $19,520 and cost/LYG was $16,930. Compared to lower risk patients, patients at higher risk of stroke (Congestive heart failure, history of Hypertension, Age ≥ 75 years, Diabetes mellitus, and past history of Stroke or transient ischemic attack (CHADS(2)) scores 3-6 versus 0) had a lower cost/QALY ($9580-$16,000 versus $26,450). Cost/QALY was highest in scenarios assuming lifetime dronedarone therapy, no cardiovascular mortality benefit, no cost associated with AF/AFL recurrence on standard care, and when discounting of 5% was compared with 0%. CONCLUSIONS: By extrapolating the results of a large, multicenter, randomized clinical trial (ATHENA), this model suggests that dronedarone is a cost-effective treatment option for approved indications (paroxysmal/persistent AF/AFL) in the US.

Cost-effectiveness analysis of dronedarone versus other anti-arrhythmic drugs for the treatment of atrial fibrillation--results for Canada, Italy, Sweden and Switzerland.

The ATHENA clinical trial enrolled 4,628 patients in 37 countries and evaluated the efficacy of dronedarone 400 mg twice daily versus placebo for the prevention of cardiovascular hospitalisation or death from any cause in patients with paroxysmal or persistent atrial fibrillation or atrial flutter. The trial showed a statistically significant 24% reduction in the primary endpoint cardiovascular hospitalisations or all-cause death. In the current paper, parameters that drive the cost-effectiveness of dronedarone on top of standard therapy versus likely comparators, i.e. amiodarone, sotalol and flecainide, were investigated by means of a health economic model based on the ATHENA clinical trial. Dronedarone is cost-effective, and ICERs are low versus amiodarone with €5,340; €4,620; €3,850 and €5,630 per QALY gained for Canada, Italy, Sweden and Switzerland, respectively. The most significant driving factor for the cost-effectiveness of dronedarone is the increased survival rate for patients on dronedarone.

Cost-effectiveness of dronedarone in atrial fibrillation: results for Canada, Italy, Sweden, and Switzerland.

BACKGROUND: Dronedarone is a therapy for the treatment of patients with paroxysmal and persistent atrial fibrillation or atrial flutter. According to results in the ATHENA trial, dronedarone on top of standard of care (SOC) decreases the risk of cardiovascular hospitalizations or death by 24% compared with SOC alone. OBJECTIVES: A patient-level health economic model was developed to evaluate the cost-effectiveness of dronedarone on top of SOC versus SOC alone. METHODS: The risk of experiencing stroke, congestive heart failure, acute coronary syndromes, treatment discontinuation, and death was modeled by separate health states, whereas adverse events were included as 1-time cost and utility decrements. State transition probabilities were primarily deduced from the patient-level data from ATHENA using survival analysis. Four sets of analyses were performed to reflect costs and treatment effects in Canada, Italy, Sweden, and Switzerland. Cost-effectiveness analysis was also conducted in a newly defined patient population identified by the European Medicines Agency (EMA) to avoid the use of dronedarone in permanent AF patients resembling those in the PALLAS study. RESULTS: The predicted survival time was, for the Canadian cohort, extended from 10.11 to 10.24 years when dronedarone was added to SOC. Similar results were found for the other countries, resulting in incremental cost-effectiveness ratios (ICERs) of €5828, €5873, €14,970, and €8554 per QALYs for Canada, Italy, Sweden, and, Switzerland, respectively. These results are all well below current established cost-effectiveness thresholds. In the EMA-restricted population, all patients were predicted to live longer, and the ICER increased but remained within established thresholds, with an average cost per QALY gained of €15,900. CONCLUSIONS: Dronedarone on top of SOC appears to be a cost-effective treatment for atrial fibrillation compared with SOC alone. Despite the differences in the local settings considered, the results were consistent among all the countries included in the study. ClinicalTrials.gov identifier: NCT00174785.
