Healthcare-Related Costs Associated with Switching Subcutaneous Tumor Necrosis Factor-α Inhibitor in the Treatment of Inflammatory Arthritis: a Retrospective Study.

INTRODUCTION: Subsequent lines of subcutaneous tumor necrosis factor alpha inhibitor (SC-TNFi) treatment may be well motivated in the management of rheumatoid arthritis (RA), ankylosing spondylitis (AS), and psoriatic arthritis (PsA)-collectively named inflammatory arthritis (IA). However, the costs associated with switching SC-TNFis are largely unknown. The objective of this retrospective observational study was to explore costs of healthcare resource utilization (HCRU) associated with switching SC-TNFi treatment among biologic-naïve Swedish patients with IA. METHODS: Using population-based register data, adult patients filling prescriptions between May 6, 2010 and December 31, 2014 for an SC-TNFi (adalimumab, etanercept, certolizumab, and golimumab) were included. Patients switching treatment (cyclers) were matched to treatment persistent patients on the basis of propensity score and follow-up time. HCRU-associated costs were captured and compared 12 months before and 12 months after the index date (defined as the date of the switch). RESULTS: A balanced cohort of 594 matched pairs was derived. Prior to the index date, cyclers had significantly higher non-treatment HCRU costs compared to persistent patients ($3815 [3498-4147] vs. $2900; 95%CI [2565-3256]). However, 12 months after the index date, cyclers had significantly increased their non-treatment HCRU costs while persistent patients lowered theirs ($822 [232-1490] vs. $- 313 [- 664-36]). This resulted in a statistically significant difference in difference of $1135 between the groups. CONCLUSIONS: In biologic-naïve patients treated with SC-TNFi for IA, cyclers significantly increased their non-treatment HCRU costs 12 months after switching treatment while persistent patients lowered their costs during the same time period. As these findings indicate that differences in treatment persistence may have an impact on costs, further research utilizing more comprehensive data sources in alternate settings is warranted.

Cost-of-illness of inflammatory bowel disease patients treated with anti-tumour necrosis factor: A French large single-centre experience.

Background: No study has evaluated the direct annual costs of inflammatory bowel disease patients treated with anti-tumour necrosis factor therapy. Objectives: The purpose of this study was to identify annual direct costs and main cost drivers of anti-tumour necrosis factor-treated inflammatory bowel disease patients. Methods: All inflammatory bowel disease patients treated with infliximab or adalimumab at Nancy University Hospital were consecutively screened for inclusion from November 2016-February 2017. Data about hospitalisation, surgery, medication, outpatient visits, investigations and transport over the previous 12 months were retrospectively collected. Results: A total of 108 patients (n = 83 Crohn's disease; n = 25 ulcerative colitis) were included. The mean annual cost per patient was €15,775 (standard deviation €7221), with no difference between Crohn's disease and ulcerative colitis (p = 0.2). The main cost driver was medication, which accounted for 84% of the total direct cost. Hospitalisation and surgery represented 11% and 2% of the direct costs. History of switch to another anti-tumour necrosis factor treatment was identified as the only independent predictor of greater direct costs in the multivariate analysis (p = 0.0018). Conclusions: In a French tertiary referral centre, direct costs of anti-tumour necrosis factor therapy-treated patients were mainly driven by medication, while hospitalisation and surgery represented only a minor part of the costs. There was no difference between Crohn's disease and ulcerative colitis patients.

The economic burden of switching targeted disease-modifying anti-rheumatic drugs among rheumatoid arthritis patients.

AIMS: To estimate real world healthcare costs and resource utilization of rheumatoid arthritis (RA) patients associated with targeted disease modifying anti-rheumatic drugs (tDMARD) switching in general and switching to abatacept specifically. MATERIALS AND METHODS: RA patients initiating a tDMARD were identified in IMS PharMetrics Plus health insurance claims data (2010-2016), and outcomes measured included monthly healthcare costs per patient (all-cause, RA-related) and resource utilization (inpatient stays, outpatient visits, emergency department [ED] visits). Generalized linear models were used to assess (i) average monthly costs per patient associated with tDMARD switching, and (ii) among switchers only, costs of switching to abatacept vs tumor necrosis factor inhibitors (TNFi) or other non-TNFi. Negative binomial regressions were used to determine incident rate ratios of resource utilization associated with switching to abatacept. RESULTS: Among 11,856 RA patients who initiated a tDMARD, 2,708 switched tDMARDs once and 814 switched twice (to a third tDMARD). Adjusted average monthly costs were higher among patients who switched to a second tDMARD vs non-switchers (all-cause: $4,785 vs $3,491, p < .001; RA-related: $3,364 vs $2,297, p < .001). Monthly RA-related costs were higher for patients switching to a third tDMARD compared to non-switchers remaining on their second tDMARD ($3,835 vs $3,383, p < .001). Switchers to abatacept had significantly lower RA-related monthly costs vs switchers to TNFi ($3,129 vs $3,436, p = .021), and numerically lower all-cause costs ($4,444 vs $4,741, p = 0.188). Switchers to TNFi relative to abatacept had more frequent inpatient stays after switch (incidence rate ratio (IRR) = 1.85, p = .031), and numerically higher ED visits (IRR = 1.32, p = .093). Outpatient visits were less frequent for TNFi switchers (IRR = 0.83, p < .001) compared to switchers to abatacept. LIMITATIONS AND CONCLUSIONS: Switching to another tDMARD was associated with higher healthcare costs. Switching to abatacept, however, was associated with lower RA-related costs, fewer inpatient stays, but more frequent outpatient visits compared to switching to a TNFi.

Second-line treatment persistence and costs among patients with immune-mediated rheumatic diseases treated with subcutaneous TNF-alpha inhibitors.

The objective of this study was to describe treatment persistence with second-line subcutaneous tumor necrosis factor-alpha inhibitors (SC-TNFis) in patients with immune-mediated rheumatic diseases (IMRDs) in Sweden, and the impact of non-persistence on healthcare costs. This retrospective observational study was based on Swedish national health register data. Adults were identified through filled prescriptions for adalimumab (ADA), etanercept (ETA), certolizumab pegol (CZP) and golimumab (GLM). Persistence was estimated over 3 years for propensity score-matched (PSM) cohorts using non-parametric survival analysis. Unadjusted comparisons of costs comprised specialized outpatient care, inpatient care, and medication. In total, N = 845 patients were identified and three PSM cohorts were generated (GLM vs. ADA, ETA, and CZP, respectively). GLM exhibited higher persistence than ADA over the study period (p = 0.040), and numerically higher persistence than ETA and CZP for 36 and 30 months, respectively. Persistent and non-persistent patients had similar mean total cost at 12 month pre-treatment ($5185 vs. $5064, p = 0.750). During the 12 month post-treatment initiation, persistent patients had lower mean total costs ($4377 vs. $6605), corresponding to a cost difference of $2228 (p < 0.001). In second-line treatment with SC-TNFis for IMRDs in Sweden, GLM exhibited significantly higher persistence than ADA over the course of the study. Similarly, GLM showed numerically higher persistence than ETA and CZP, which is concurrent with results observed in first-line SC-TNFi treatment. Considering the lower healthcare costs for persistent patients, the choice of second-line SC-TNFi among eligible patients may merit careful consideration given its impact on patients and payers.

Costs associated with failure to respond to treatment among patients with rheumatoid arthritis initiating TNFi therapy: a retrospective claims analysis.

BACKGROUND: Tumor necrosis factor inhibitors (TNFi) are common second-line treatments for rheumatoid arthritis (RA). This study was designed to compare the real-world clinical and economic outcomes between patients with RA who responded to TNFi therapy and those who did not. METHODS: For this retrospective cohort analysis we used medical and pharmacy claims from members of 14 large U.S. commercial health plans represented in the HealthCore Integrated Research Database. Adult patients (aged ≥18 years) diagnosed with RA and initiating TNFi therapy (index date) between 1 January 2007 and 30 April 2014 were included in the study. Treatment response was assessed using a previously developed and validated claims-based algorithm. Patients classified as treatment responders in the 12 months postindex were matched 1:1 to nonresponders on important baseline characteristics, including sex, age, index TNFi agent, and comorbidities. The matched cohorts were then compared on their all-cause and RA-related healthcare resource use, and costs were assessed from a payer perspective during the first, second, and third years postindex using parametric tests, regressions, and a nonparametric bootstrap. RESULTS: A total of 7797 patients met the study inclusion criteria, among whom 2337 (30%) were classified as treatment responders. The responders had significantly lower all-cause hospitalizations, emergency department visits, and physical/occupational therapy visits than matched nonresponders during the first-year postindex. Mean total all-cause medical costs were $5737 higher for matched nonresponders, largely driven by outpatient visits and hospitalizations. Mean all-cause pharmacy costs (excluding costs of biologics) were $354 higher for matched nonresponders. Mean RA-related pharmacy costs (conventional synthetic and biologic drugs), however, were $8579 higher in the responder cohort, driven by higher adherence to their index TNFi agent (p < 0.01 for all comparisons). A similar pattern of cost differentiation was observed over years 2 and 3 of follow-up. CONCLUSIONS: In this real-world study we found that, compared with matched nonresponders, patients who responded to TNFi treatments had lower all-cause medical, pharmacy, and total costs (excluding biologics) up to 3 years from initiation of TNFi therapy. These cost differences between the two cohorts provide a considerable offset to the cost of RA medications and should encourage close monitoring of treatment response to minimize disease progression with appropriate therapy choices.

A microcosting study of immunogenicity and tumour necrosis factor alpha inhibitor drug level tests for therapeutic drug monitoring in clinical practice.

OBJECTIVES: To identify and quantify resource required and associated costs for implementing TNF-α inhibitor (TNFi) drug level and anti-drug antibody (ADAb) tests in UK rheumatology practice. METHODS: A microcosting study, assuming the UK National Health Service perspective, identified the direct medical costs associated with providing TNFi drug level and ADAb testing in clinical practice. Resource use and costs per patient were identified via four stages: identification of a patient pathway with resource implications; estimation of the resources required; identification of the cost per unit of resource (2015 prices); and calculation of the total costs per patient. Univariate and multiway sensitivity analyses were performed using the variation in resource use and unit costs. RESULTS: Total costs for TNFi drug level and concurrent ADAb testing, assessed using ELISAs on trough serum levels, were £152.52/patient (range: £147.68-159.24) if 40 patient samples were tested simultaneously. For the base-case analysis, the pre-testing phase incurred the highest costs, which included booking an additional appointment to acquire trough blood samples. The additional appointment was the key driver of costs per patient (67% of the total cost), and labour accounted for 10% and consumables 23% of the total costs. Performing ELISAs once per patient (rather than in duplicate) reduced the total costs to £133.78/patient. CONCLUSION: This microcosting study is the first assessing the cost of TNFi drug level and ADAb testing. The results could be used in subsequent cost-effectiveness analyses of TNFi pharmacological tests to target treatments and inform future policy recommendations.

Clinical Outcomes and Biologic Costs of Switching Between Tumor Necrosis Factor Inhibitors in US Veterans with Rheumatoid Arthritis.

INTRODUCTION: The purpose of this study was to evaluate clinical outcomes and drug/administration costs of treatment with tumor necrosis factor inhibitor (TNFi) agents in US veterans with rheumatoid arthritis (RA) initiating TNFi therapy. The analysis compared patients initiating and continuing a single TNFi with patients who subsequently switched to a different TNFi. METHODS: Data from patients enrolled in the Veterans Affairs Rheumatoid Arthritis (VARA) registry who initiated treatment with adalimumab, etanercept, or infliximab from 2003 to 2010 were analyzed. Outcomes included duration of therapy, Disease Activity Score based on 28 joints (DAS28), and direct drug and drug administration costs. RESULTS: Of 563 eligible patients, 262 initiated a single TNFi therapy, 142 restarted their initial TNFi after a ≥90-day gap in treatment (interrupted therapy), and 159 switched to a different TNFi. Patients who switched had higher mean DAS28 before starting TNFi therapy than patients with single or interrupted therapy: 5.3 vs 4.5 or 4.6, respectively. Mean duration of the first course was 34.3 months for single therapy, 18.3 months for interrupted therapy, and 17.7 months for switched therapy. Mean post-treatment DAS28 was highest for patients who switched TNFi. Mean annualized costs for first course were $13,800 for single therapy, $13,200 for interrupted therapy, and $14,200 for switched therapy; mean annualized costs for second course were $12,800 for interrupted therapy and $15,100 for switched therapy. CONCLUSION: Patients who switched TNFi had higher pre-treatment DAS28 and higher overall costs than patients who received the same TNFi as either single or interrupted therapy. FUNDING: This research was funded by Immunex Corp., a fully owned subsidiary of Amgen Inc., and by VA HSR&D Grant SHP 08-172.

Evolution of Costs of Inflammatory Bowel Disease over Two Years of Follow-Up.

BACKGROUND: With the increasing use of anti-TNF therapy in inflammatory bowel disease (IBD), a shift of costs has been observed with medication costs replacing hospitalization and surgery as major cost driver. We aimed to explore the evolution of IBD-related costs over two years of follow-up. METHODS AND FINDINGS: In total 1,307 Crohn's disease (CD) patients and 915 ulcerative colitis (UC) patients were prospectively followed for two years by three-monthly web-based questionnaires. Changes of healthcare costs, productivity costs and out-of-pocket costs over time were assessed using mixed model analysis. Multivariable logistic regression analysis was used to identify costs drivers. In total 737 CD patients and 566 UC were included. Total costs were stable over two years of follow-up, with annual total costs of €7,835 in CD and €3,600 in UC. However, within healthcare costs, the proportion of anti-TNF therapy-related costs increased from 64% to 72% in CD (p<0.01) and from 31% to 39% in UC (p < 0.01). In contrast, the proportion of hospitalization costs decreased from 19% to 13% in CD (p<0.01), and 22% to 15% in UC (p < 0.01). Penetrating disease course predicted an increase of healthcare costs (adjusted odds ratio (adj. OR) 1.95 (95% CI 1.02-3.37) in CD and age <40 years in UC (adj. OR 4.72 (95% CI 1.61-13.86)). CONCLUSIONS: BD-related costs remained stable over two years. However, the proportion of anti-TNF-related healthcare costs increased, while hospitalization costs decreased. Factors associated with increased costs were penetrating disease course in CD and age <40 in UC.

Vedolizumab for the Treatment of Adults with Moderate-to-Severe Active Ulcerative Colitis: An Evidence Review Group Perspective of a NICE Single Technology Appraisal.

As part of its single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited the manufacturer of vedolizumab (Takeda UK) to submit evidence of the clinical effectiveness and cost effectiveness of vedolizumab for the treatment of patients with moderate-to-severe active ulcerative colitis (UC). The Evidence Review Group (ERG) produced a critical review of the evidence for the clinical effectiveness and cost effectiveness of the technology, based upon the company's submission to NICE. The evidence was derived mainly from GEMINI 1, a Phase 3, multicentre, randomised, double-blinded, placebo-controlled study of the induction and maintenance of clinical response and remission by vedolizumab (MLN0002) in patients with moderate-to-severe active UC with an inadequate response to, loss of response to or intolerance of conventional therapy or anti-tumour necrosis factor (TNF)-α. The clinical evidence showed that vedolizumab performed significantly better than placebo in both the induction and maintenance phases. In the post hoc subgroup analyses in patients with or without prior anti-TNF-α therapy, vedolizumab performed better then placebo (p value not reported). In addition, a greater improvement in health-related quality of life was observed in patients treated with vedolizumab, and the frequency and types of adverse events were similar in the vedolizumab and placebo groups, but the evidence was limited to short-term follow-up. There were a number of limitations and uncertainties in the clinical evidence base, which warrants caution in its interpretation--in particular, the post hoc subgroup analyses and high dropout rates in the maintenance phase of GEMINI 1. The company also presented a network meta-analysis of vedolizumab versus other biologic therapies indicated for moderate-to-severe UC. However, the ERG considered that the results presented may have underestimated the uncertainty in treatment effects, since fixed-effects models were used, despite clear evidence of heterogeneity among the trials included in the network. Results from the company's economic evaluation (which included price reductions to reflect the proposed patient access scheme for vedolizumab) suggested that vedolizumab is the most effective option compared with surgery and conventional therapy in the following three populations: (1) a mixed intention-to-treat population, including patients who have previously received anti-TNF-α therapy and those who are anti-TNF-α naïve; (2) patients who are anti-TNF-α naïve only; and (3) patients who have previously failed anti-TNF-α therapy only. The ERG concluded that the results of the company's economic evaluation could not be considered robust, because of errors in model implementation, omission of relevant comparators, deviations from the NICE reference case and questionable model assumptions. The ERG amended the company's model and demonstrated that vedolizumab is expected to be dominated by surgery in all three populations.

The cost of multiple sclerosis drugs in the US and the pharmaceutical industry: Too big to fail?

OBJECTIVE: To examine the pricing trajectories in the United States of disease-modifying therapies (DMT) for multiple sclerosis (MS) over the last 20 years and assess the influences on rising prices. METHODS: We estimated the trend in annual drug costs for 9 DMTs using published drug pricing data from 1993 to 2013. We compared changes in DMT costs to general and prescription drug inflation during the same period. We also compared the cost trajectories for first-generation MS DMTs interferon (IFN)-ß-1b, IFN-ß-1a IM, and glatiramer acetate with contemporaneously approved biologic tumor necrosis factor (TNF) inhibitors. RESULTS: First-generation DMTs, originally costing $8,000 to $11,000, now cost about $60,000 per year. Costs for these agents have increased annually at rates 5 to 7 times higher than prescription drug inflation. Newer DMTs commonly entered the market with a cost 25%-60% higher than existing DMTs. Significant increases in the cost trajectory of the first-generation DMTs occurred following the Food and Drug Administration approvals of IFN-ß-1a SC (2002) and natalizumab (reintroduced 2006) and remained high following introduction of fingolimod (2010). Similar changes did not occur with TNF inhibitor biologics during these time intervals. DMT costs in the United States currently are 2 to 3 times higher than in other comparable countries. CONCLUSIONS: MS DMT costs have accelerated at rates well beyond inflation and substantially above rates observed for drugs in a similar biologic class. There is an urgent need for clinicians, payers, and manufacturers in the United States to confront the soaring costs of DMTs.

ABSTRACT Objective Identify factors associated with the workload of nursing care for patients in the postoperative period of cardiac surgery. Method Prospective cohort study conducted with 187 patients in the surgical intensive care unit (ICU) of the Instituto do Coração(Heart Institute) in São Paulo-Brazil. Data were collected at 24 and 72 hours of the patients’ admittance in the ICU. The dependent variable was workload as calculated by the Nursing Activities Score (NAS). The independent variables were demographic and clinical, as well as mortality scores. For data analysis, the Wilcoxon-Mann-Whitney test and Spearman correlation were used, and linear regression with mixed effects model. Results The majority of patients were male (59.4%), with a mean age of 61 years (±12.7), and 43.9% developed some kind of complication in the postoperative period. In the first 24 hours, the workload was 82.4% (±3.4), and 58.1% (±3.4) in 72 hours. Factors associated with increased NAS were: patient’s length of stay in the ICU (p=0.036) and the presence of complications (p<0.001). Conclusion In contrast to numerous other studies, the severity of the patient’s condition in the first 24 hours of the postoperative period did not increase workload, the increase was associated with length of stay in the ICU and complications.

Method This was an experimental and laboratory study. The sample consisted of 130 hydrodissection cannulas, 26 per experimental group, characterized according to type of water used in the final rinse. The samples were submitted to internal and external contamination challenge with a solution containing 20% defibrinated sheep blood and 80% of sodium chloride 0.9%. Next, the lumens were filled with a ophthalmic viscosurgical device, remaining exposed for 50 minutes, and then were processed according to the validated SOP. Cytotoxicity was assessed using neutral red uptake assay. Results No cytoxicity was detected in the sample extracts. Conclusion The samples did not display signs of cytotoxicity, regardless of final rinse quality. The results obtained were reached by using only a validated cleaning operating procedure, based on the scientific literature, and on official recommendations and related regulation.

Biosimilars: in support of extrapolation of indications.

Biosimilars have the potential to lead to enormous cost savings in healthcare without reducing the level of care for patients. In Europe, biosimilars have to demonstrate comparability in an extensive biosimilarity exercise including analytical, preclinical and comparative clinical studies. By successfully completing the biosimilarity exercise, the biosimilar shows that all aspects that are considered relevant for the clinical activity of the product fall within the same range as observed for the innovator. It should be carefully considered whether the benefit of additional information from more comparative clinical studies weighs up to the additional barriers such studies create for biosimilars to enter clinical practice.
