RESUMEN
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.

INTRODUCTION: Assess the cost-effectiveness (US healthcare payer perspective) of sarilumab subcutaneous (SC) 200 mg + methotrexate versus conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) or targeted DMARD + methotrexate for moderate-to-severe rheumatoid arthritis (RA) in adults with inadequate response to methotrexate. METHODS: Microsimulation based on patient profiles from MOBILITY (NCT01061736) was conducted via a 6-month decision tree and lifetime Markov model with 6-monthly cycles. Treatment response at 6 months was informed by a network meta-analysis and based on American College of Rheumatology (ACR) response. Responders: patients with ACR20 response who continued with therapy; non-responders: ACR20 non-responders who transitioned to the subsequent treatment. Utilities and quality-adjusted life-years (QALYs) were estimated via mapping 6-month ACR20/50/70 response to relative change in Health Assessment Questionnaire Disability Index score (short term) and based on published algorithms (long term). Direct costs considered drugs (wholesale acquisition costs), administration and routine care. RESULTS: Lifetime QALYs and costs for treatment sequences on the efficiency frontier were 3.43 and $115,019 for active csDMARD, 5.79 and $430,918 for sarilumab, and 5.94 and $524,832 for etanercept (all others dominated). Sarilumab was cost-effective versus tocilizumab and csDMARD (incremental cost-effectiveness ratios of $84,079/QALY and $134,286/QALY). Probabilistic sensitivity analysis suggested comparable costs and slightly improved health benefits for sarilumab versus tocilizumab, irrespective of threshold. CONCLUSION: In patients with moderate-to-severe RA, sarilumab 200 mg SC every 2 weeks + methotrexate can be considered a cost-effective treatment option, with lower costs and greater health benefits than alternative treatment sequences (+ methotrexate) beginning with adalimumab, certolizumab, golimumab and tofacitinib and below commonly accepted cost-effectiveness thresholds against tocilizumab + methotrexate or csDMARD active treatment.

Objective: This paper aims to summarize the key findings of the updated report issued in August 2018 by the Institute of Clinical and Economic Review (ICER) regarding the clinical efficacy and budget impact of various immunomodulators. Methods: This paper specifically focuses on the inclusion of two new biologics, guselkumab and certolizumab in the context of their relative cost-effectiveness using analyses on sequential implementation of specific first- and second-line therapies. Results: The ICER found that initiating biologic therapy with an IL-17 inhibitor or guselkumab results in the most clinical improvement, but is also associated with higher costs. The ICER also found that guselkumab and certolizumab would need to be discounted significantly in order to achieve cost-effectiveness by standard metrics of $50,000-$150,000 per QALY. Conclusion: The ICER report demonstrates a need for more consensus guidelines in the use of biologics in the treatment of psoriasis, and perhaps consideration of costs within these guidelines.

OBJECTIVES: Switching to a different mechanism of action in rheumatoid arthritis (RA) patients after a first anti-TNF-α has proved to be effective. The objective of this study was a health economic assessment in Italy. METHODS: The study was conducted using a pharmacoeconomic model with a 3-year time horizon. Effectiveness was measured as days gained in low disease activity (LDA; DAS28-ESR <3.2) or in remission (DAS28-ESR <2.6). The model simulated the response to treatments, based on the Rotation Or Change (ROC) trial, the probability of discontinuation and switch to a 3rd-line biologic, and the transition to death. Time on treatment curves for 2nd-line biologics were derived from published Italian real-word data. Costs were estimated based on published sources and Italian prices and tariffs. RESULTS: The switch to tocilizumab after the failure of a first anti-TNF-α was more effective than a second anti-TNF-α, in terms of days in remission (224 vs. 114 days) and of days in LDA (345 vs. 193 days). The cost-consequence ratio with tocilizumab iv was 174 euros/day in remission and 113 euros/day in LDA. With tocilizumab sc the ratio was 181 euros/day in remission and 117 euros/day in LDA. The same ratios for the anti-TNF-α treatments ranged from 233 to Euro 320 euros per day in remission and from 138 to 190 euros per day in LDA. CONCLUSIONS: The switch to a different mechanism of action, namely tocilizumab, after the failure of a first anti-TNF-α agent seems a rational strategy for RA patients in the Italian setting.

PURPOSE: To model the American College of Rheumatology (ACR) outcomes, cost-effectiveness, and budget impact of certolizumab pegol (CZP) (with and without a hypothetical risk-sharing scheme at treatment initiation for biologic-naïve patients) versus the current mix of reimbursed biologics for treatment of moderate-to-severe rheumatoid arthritis (RA) in Finland. METHODS: A probabilistic model with 12-week cycles and a societal approach was developed for the years 2015-2019, accounting for differences in ACR responses (meta-analysis), mortality, and persistence. The risk-sharing scheme included a treatment switch and refund of the costs associated with CZP acquisition if patients failed to achieve ACR20 response at week 12. For the current treatment mix, ACR20 at week 24 determined treatment continuation. Quality-adjusted life years were derived on the basis of the Health Utilities Index. RESULTS: In the Finnish target population, CZP treatment with a risk-sharing scheme led to a estimated annual net expenditure decrease ranging from 1.7% in 2015 to 5.6% in 2019 compared with the current treatment mix. Per patient over the 5 years, CZP risk sharing was estimated to decrease the time without ACR response by 5%-units, decrease work absenteeism by 24 days, and increase the time with ACR20, ACR50, and ACR70 responses by 5%-, 6%-, and 1%-units, respectively, with a gain of 0.03 quality-adjusted life years. The modeled risk-sharing scheme showed reduced costs of 7866 per patient, with a more than 95% probability of cost-effectiveness when compared with the current treatment mix. CONCLUSION: The present analysis estimated that CZP, with or without the risk-sharing scheme, is a cost-effective alternative treatment for RA patients in Finland. The surplus provided by the CZP risk-sharing scheme could fund treatment for 6% more Finnish RA patients. FUNDING: UCB Pharma.

INTRODUCTION: After a patient with rheumatoid arthritis (RA) fails tumor necrosis factor inhibitor (TNFi) treatment, clinical guidelines support either cycling to another TNFi or switching to a different mechanism of action (MOA), but payers often require TNFi cycling before they reimburse switching MOA. This study examined treatment persistence, cost, and cost per persistent patient among MOA switchers versus TNFi cyclers. METHODS: This study of Commercial and Medicare Advantage claims data from the Optum Research Database included patients with RA and at least one claim for a TNFi (adalimumab, certolizumab pegol, etanercept, golimumab, or infliximab) between January 2012 and September 2015 who changed to another TNFi or a different MOA therapy (abatacept, tocilizumab, or tofacitinib) within 1 year. The index date was the date of the change in therapy. Treatment persistence was defined as no subsequent switch or 60-day gap in therapy for 1 year post-index. RA-related costs included plan-paid and patient-paid amounts for inpatient, outpatient, and pharmacy claims. Medication costs included index and post-index costs of TNFi and different MOA therapies. RESULTS: There were 581 (38.3%) MOA switchers and 935 (61.7%) TNFi cyclers. The treatment persistence rate was significantly higher for MOA switchers versus TNFi cyclers (47.7% versus 40.2%, P = 0.004). Mean 1-year healthcare costs were significantly lower among MOA switchers versus TNFi cyclers for total RA-related costs ($37,804 versus $42,116; P < 0.001) and medication costs ($29,001 versus $34,917; P < 0.001). When costs were divided by treatment persistence, costs per persistent patient were lower among MOA switchers versus TNFi cyclers: $25,436 lower total RA-related cost and $25,999 lower medication costs. CONCLUSION: MOA switching is associated with higher treatment persistence and lower healthcare costs than TNFi cycling. Reimbursement policies that require patients to cycle TNFi before switching MOA may result in suboptimal outcomes for both patients and payers. FUNDING: Sanofi and Regeneron Pharmaceuticals.

We aimed to evaluate the cost-effectiveness of certolizumab pegol (CZP), a pegylated fc-free anti-TNF, as add-on therapy to methotrexate (MTX) versus etanercept, adalimumab, or golimumab in patients with moderate-to-severe active rheumatoid arthritis (RA) not responding to the conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs). A Markov model (6-month cycle length) assessed health and cost outcomes of CZP versus other anti-TNFs recommended for RA in Greece over a patient's lifetime. Following discontinuation of first-line anti-TNF, patients switched to second anti-TNF and then to a biologic with another mode of action. Sequential use of csDMARDs followed third biologic. Clinical data and utilities were extracted from published literature. Analysis was conducted from third-party payer perspective in Greece. Costs (drug acquisition, administration, monitoring, and patient management) were considered for 2014. Results presented are incremental cost-effectiveness ratios (ICERs) per quality-adjusted life year (QALY). Probabilistic sensitivity analysis (PSA) ascertained robustness of base-case findings. Base-case analysis indicated that CZP+MTX was more costly and more effective compared with Etanercept+MTX (base-case ICER: 3,177 per QALY), whilst versus adalimumab/golimumab, CZP was dominant (less costly, more effective). For all comparisons, CZP treatment resulted in greater improvements in life expectancy and QALYs. PSA indicated that at the willingness-to-pay threshold of 34,000/QALY, CZP+MTX was associated with a 71.6, 97.9, or 99.2% probability of being cost-effective versus etanercept, golimumab, or adalimumab, respectively, in combination with MTX. This analysis demonstrates CZP+MTX to be a cost-effective alternative over Etanercept+MTX and a dominant option over Adalimumab+MTX and Golimumab+MTX for management of RA in Greece.

As part of its single technology appraisal (STA) process, the National Institute for Health and Care Excellence (NICE) invited the manufacturer (UCB Pharma) of certolizumab pegol (CZP; Cimzia®) to submit evidence of its clinical and cost effectiveness for the treatment of rheumatoid arthritis (RA) following inadequate response to a tumour necrosis factor-α inhibitor (TNFi). The School of Health and Related Research Technology Appraisal Group at the University of Sheffield was commissioned to act as the independent Evidence Review Group (ERG). The ERG produced a detailed review of the evidence for the clinical and cost effectiveness of the technology, based upon the company's submission to NICE. The clinical effectiveness evidence in the company's submission for CZP was based predominantly on six randomised controlled trials (RCTs) comparing the efficacy of CZP against placebo. The clinical effectiveness review identified no head-to-head evidence on the efficacy of CZP against the comparators within the scope; therefore, the company performed a network meta-analysis (NMA). The company's NMA concluded that CZP had a similar efficacy to that of its comparators. The company submitted a Markov model that assessed the incremental cost effectiveness of CZP versus comparator biologic disease-modifying antirheumatic drugs (bDMARDs) for the treatment of RA from the perspective of the National Health Service for three decision problems, each of which followed an inadequate response to a TNFi. These were (1) a comparison against rituximab (RTX) in combination with methotrexate (MTX); (2) a comparison against bDMARDs when RTX was contraindicated or withdrawn due to an adverse event; and (3) a comparison against bDMARDs when MTX was contraindicated or withdrawn due to an adverse event. Results from the company's economic evaluation showed that CZP resulted in a similar number of quality-adjusted life years (QALYs) produced at similar or lower costs compared with comparator bDMARDs. The commercial-in-confidence patient access schemes for abatacept and tocilizumab could not be incorporated by the company, but were incorporated by the ERG in a confidential appendix for the NICE Appraisal Committee (AC). The company estimated that the addition of CZP before RTX in a sequence for patients who could receive MTX produced more QALYs at an increased cost, with a cost per QALY of £33,222. Following a critique of the model, the ERG undertook exploratory analyses that did not change the conclusions reached based on the company's economic evaluation in relation to the comparison with bDMARDs. The ERG estimated that where CZP replaced RTX, CZP was dominated, as it produced fewer QALYs at an increased cost. The AC concluded that there was little difference in effectiveness between CZP and comparator bDMARDs and that equivalence among bDMARDs could be accepted. The AC consequently recommended CZP plus MTX for people for whom RTX is contraindicated or not tolerated and CZP monotherapy for people for whom MTX is contraindicated or not tolerated. The AC concluded that CZP plus MTX could not be considered a cost-effective use of National Health Service resources when RTX plus MTX is a treatment option.

AIMS: To determine the cost-effectiveness of treatment sequences of biologic disease-modifying anti-rheumatic drugs or Janus kinase/STAT pathway inhibitors (collectively referred to as bDMARDs) vs conventional DMARDs (cDMARDs) from the US societal perspective for treatment of patients with moderately to severely active rheumatoid arthritis (RA) with inadequate responses to cDMARDs. MATERIALS AND METHODS: An individual patient simulation model was developed that assesses the impact of treatments on disease based on clinical trial data and real-world evidence. Treatment strategies included sequences starting with etanercept, adalimumab, certolizumab, or abatacept. Each of these treatment strategies was compared with cDMARDs. Incremental cost, incremental quality-adjusted life-years (QALYs), and incremental cost-effectiveness ratios (ICERs) were calculated for each treatment sequence relative to cDMARDs. The cost-effectiveness of each strategy was determined using a US willingness-to-pay (WTP) threshold of $150,000/QALY. RESULTS: For the base-case scenario, bDMARD treatment sequences were associated with greater treatment benefit (i.e. more QALYs), lower lost productivity costs, and greater treatment-related costs than cDMARDs. The expected ICERs for bDMARD sequences ranged from â¼$126,000 to $140,000 per QALY gained, which is below the US-specific WTP. Alternative scenarios examining the effects of homogeneous patients, dose increases, increased costs of hospitalization for severely physically impaired patients, and a lower baseline Health Assessment Questionnaire (HAQ) Disability Index score resulted in similar ICERs. CONCLUSIONS: bDMARD treatment sequences are cost-effective from a US societal perspective.

Anti-tumour necrosis factor (TNF) agents are recommended as second-line therapy for patients with axial spondyloarthropathies. This analysis reviewed data on studies investigating the efficacy and tolerability of anti-TNF agents in patients with non-radiographic axial spondyloarthritis (nr-axSpA) who had failed first-line non-steroidal anti-inflammatory (NSAID) treatment. Efficacy data from RCTs were used to calculate the number needed to treat (NNT) for individual anti-TNFs and then the cost per responder was determined to provide an indication of the value of each therapy. A systematic literature review and analysis of search results over the period January 2008 to September 2014 identified four randomised placebo-controlled trials that were included in the analysis. Adalimumab, etanercept and certolizumab pegol were all effective and well tolerated in patients with nr-axSpA. A patient was more likely to reach ASAS20 or ASAS40 when treated with etanercept or adalimumab, the NNT was lowest for adalimumab, and the risk of adverse events was higher with certolizumab pegol 200 mg every 2 weeks. The cost per responder (NNT) was lowest for adalimumab, followed closely by certolizumab 400 mg every 4 weeks, intermediate for certolizumab 200 mg every 2 weeks and highest for etanercept. Although all anti-TNF agents were associated with clinical improvement in patients with nr-axSpA, adalimumab presented a better cost per responder than etanercept and certolizumab pegol.

INTRODUCTION: Only limited information is available on cost efficacy of the various biological agents used to treat patients with rheumatoid arthritis with intolerance or for whom it would be inappropriate to continue treatment with conventional agents. We estimated the efficacy and treatment costs of monotherapy with biological agents in the treatment of this group of patients. METHODS: Data from two previous meta-analyses in the treatment of patients who are intolerant to methotrexate (MTX), or for whom it would be inappropriate to continue treatment with MTX was used. Pharmacoeconomic comparison between biological agents was carried out to estimate the respective cost for the number needed to treat (NNT) compared to placebo using both American College of Rheumatology (ACR) and European League Against Rheumatism (EULAR) criteria. The analysis involved the four agents approved in Italy: adalimumab (ADA), etanercept (ETN), certolizumab pegol (CTZ), and tocilizumab (TCZ). A six-month period was considered sufficient to understand the most important differences in efficacy and treatment costs. Direct medical costs, including pharmacological therapy, administration and monitoring were considered. RESULTS: Using both ACR and EULAR criteria, TCZ (intravenous [iv]/subcutaneous [sc]) had a lower NNT than the other agents. The difference in NNT observed for ETN was more pronounced with EULAR criteria, whereas in the comparison with ADA, the most sensitive differences were observed with ACR criteria. ETN had the lowest treatment cost (6402.19), followed by ADA (6698.84), TCZ sc (6887.61), and TCZ iv (7130.83). TCZ sc had the lowest cost for NNT with both ACR and EULAR criteria. The differences compared to ETN and ADA were significant and related with the level of efficacy. Sensitivity analysis confirmed these results. CONCLUSION: TCZ is a cost-effective therapeutic option compared to other tumor necrosis factor-α inhibitors (ADA, ETA, CTZ) as first-line monotherapy for patients who are intolerant to MTX, or for whom it is inappropriate to continue treatment with MTX.

OBJECTIVES: To evaluate the cost-effectiveness of a Treat-to-Target strategy with certolizumab pegol in patients with rheumatoid arthritis in the context of a pay-for-performance agreement in which medication costs are refunded in case of discontinuation during the first 3 months of treatment. METHODS: The Treat-to-Target strategy consisted of a systematic switch to second-line tumor necrosis factor (TNF)α inhibitor in case of an unmet ACR50 response at 3 months compared to current routine clinical practice. A reference cohort treated first-line with certolizumab pegol according to current practice without systematic switching was considered as the comparator. A decision-tree model was constructed to estimate clinical outcome (health assessment questionnaire-disability index or HAQ-DI score), time spent in ACR50 response (ACR 50), and direct costs of treatment over a 2-year period. HAQ scores were derived from American College of Rheumatology 50 (ACR50) responses. All TNFα inhibitors were assumed to have equivalent efficacy and tolerability. Costs were estimated at 2013 French retail prices (date of the pay-for-performance agreement). RESULTS: The mean duration of an ACR50 response was 1.23 years in the Treat-to-Target strategy certolizumab pegol cohort vs 0.98 years in the reference cohort, resulting in a mean gain in HAQ at 24 months of 0.117. The Treat-to-Target strategy with a mix of TNFα inhibitors as second-line therapy was more expensive than the reference strategy in absolute terms, but this difference was entirely offset by the pay-for-performance agreement. The Treat-to-Target strategy was, thus, cost-neutral over a 2-year period after the payback of CZP cost for patients not achieving the target at 3 months. CONCLUSIONS: In the context of a pay-for-performance agreement, the management of patients with rheumatoid arthritis using a Treat-to-Target strategy with certolizumab pegol in first line is dominant compared to standard use of this drug in the French setting in 2013.

The main objective of this study was to describe real-world treatment persistence with subcutaneous tumor necrosis factor-alpha inhibitors (SC-TNFi) in patients with ankylosing spondylitis, psoriatic arthritis, or rheumatoid arthritis [collectively immune-mediated rheumatic disease, (IMRD)] in Sweden. A secondary objective was to describe potential effects on health care resource utilization (HCRU) cost from non-persistence. Patients were identified through filled prescriptions for adalimumab (ADA), etanercept (ETA), certolizumab pegol (CZP), and golimumab (GLM) between 5/6/2010 and 12/31/2012 from the Swedish Prescribed Drug Register. Persistence was estimated using survival analysis. Costs were derived from HCRU and comprised specialized outpatient care, inpatient care and non-disease-modifying antirheumatic drug medications. A total of 4903 patients were identified (ADA: 1823, ETA: 1704, CZP: 622, GLM: 754). Comparisons over 3 years showed that GLM had significantly higher persistence than ADA (p = 0.022) and ETA (p = 0.004). The mean difference in non-biologic HCRU costs between persistent and non-persistent patients was higher after compared to before the start of biologic therapy. SC-TNFi-naïve IMRD patients initiating treatment with GLM had significantly higher persistence rates than patients initiating treatment with ADA or ETA in Sweden. Furthermore, persistence rates observed in the study were lower than those observed in clinical trials, highlighting the need for an all-party (provider-patient-payer-drug manufacturer) engagement and development of programs to increase persistence rates in clinical practice, thus leading to improved clinical outcomes. In addition, the results of this study indicate that persistence to treatment with SC-TNFi may be associated with cost offsets in terms of non-biologic costs.

Biological disease-modifying antirheumatic drugs (bDMARDs) for rheumatoid arthritis (RA) treatment were among the first high-cost medicines to be subsidised in Australia. High-cost medicines pose several challenges to the Australian National Medicines Policy, which aims to provide timely access to effective medicines at a cost individuals and the community can afford. Thus, novel restriction criteria were developed to encourage cost-effective use of bDMARDs. Government expenditure on bDMARD subsidies for RA treatment grew to about $383 million in 2014. Evidence that initiation and continuation criteria for bDMARDs meet usually applied cost-benefit criteria is lacking. The combined expenditure on tocilizumab, certolizumab pegol and golimumab (added to the Australian Government's Pharmaceutical Benefits Scheme in 2010) was $93 million in 2014, which is 210% over the initial estimate. Present and future challenges with regard to bDMARDs for RA and other high-cost drugs include improved expenditure predictions, monitoring of cost-effectiveness in relation to actual use and strategic development, regulation and use of biosimilars. Ten years of documentation on clinical and laboratory findings indicating eligibility to initiate and continue on bDMARDs remains un-used. These data represent an untapped opportunity to promote quality of use of bDMARDs and biosimilars and to improve cost predictions for high-cost drugs.

PURPOSE: Pharmacy benefits management companies have emerged as the national standard for the management of prescription drugs in the United States. The objective of this study was to estimate the annual costs per treated patient of 8 biologics indicated for select immune-mediated inflammatory diseases: moderate to severe rheumatoid arthritis, moderate to severe plaque psoriasis, active psoriatic arthritis, and/or active ankylosing spondylitis. METHODS: Using the Medco pharmacy benefits-management database, data from patients aged 18 to 63 years with ≥1 claim for abatacept, adalimumab, certolizumab, etanercept, golimumab, infliximab, rituximab, or ustekinumab, dated between January 1, 2008 and August 31, 2011, were collected. Eligible patients were continuously enrolled for ≥180 days before and 360 days after the date of the first biologic claim (index date), and had ≥1 claim associated with a diagnosis of rheumatoid arthritis, moderate to severe plaque psoriasis, active psoriatic arthritis, and/or active ankylosing spondylitis in the 180 days before or 30 days after the index date. The annual total costs per treated patient were calculated as the total dose of the index biologic and all other biologics for which there was a claim in the postindex period, multiplied by the wholesale acquisition cost as of October 1, 2013, plus the costs associated with administrations (calculated as number of infusions multiplied by the 2013 Medicare Physician Fee Schedule costs). FINDINGS: Within the study population (N = 8306; 5356 (64.5%) women, 2950 men (35.5%), average age: 42.3 years (SD: 10.0)), the most commonly used biologics were etanercept (43.1%), adalimumab (31.0%), and infliximab (17.0%), which accounted for 91.1% of all biologic prescriptions. Total costs per treated patient across indications were as follows: adalimumab, $23,427 to $26,304; infliximab, $22,824 to $28,907; and etanercept, $21,468 to $27,748, whereas abatacept, certolizumab, golimumab, rituximab, and ustekinumab were associated with a larger range: $17,017 to $41,888. IMPLICATIONS: The present study provides insight into the prescribing patterns and cost differences among 8 biologic agents used for the treatment of immune-mediated inflammatory diseases. This information may prove useful when designing a pharmacy benefits-management formulary.
