Real-world biologic treatment patterns and healthcare resource utilization in psoriasis patients using an insurance claims database in Japan. J DERMATOL TREAT 2024; 35:2299598. [PMID: 38317525 DOI: 10.1080/09546634.2023.2299598] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2023] [Accepted: 12/11/2023] [Indexed: 02/07/2024]
Abstract
BACKGROUND With advent of newer treatments for psoriasis, real-world use of biologics in Japan is evolving. METHODS This retrospective study utilized data from patients with ≥1 psoriasis-related biologic claims record between January 2016 and December 2020 in Japan to evaluate treatment patterns, healthcare resource utilization (HCRU), and associated costs. Data were analyzed using descriptive statistics. RESULTS Of 1,614 eligible patients, 72.5% were male, 29.2% had comorbid hypertension and 26.6% had comorbid cardiovascular disease. Interleukin (IL)-17 and tumor necrosis factor alpha (TNFα) inhibitors were commonly prescribed across lines of treatment, while IL-23 inhibitors were most considered for switches (92% of switches were from IL-12/23/IL-17/TNFα inhibitors). The overall mean adherence rate for all classes was 80.1%, but adherence varied across biologics. Infliximab and IL-23 inhibitor users exhibited optimal medical possession ratios, reflecting the best adherence rates. Overall HCRU (visits/patient-year) was 9.05 for outpatient visits, 0.09 for inpatient hospitalization, and 0.5 for psoriasis-related phototherapy. HCRU associated with hospitalization was slightly higher for bio-experienced patients and so was the overall costs per patient-year relative to bio-naïve patients. CONCLUSION Variable adherence rates observed suggest the need for improvement in treatment management with different biologics. Bio-experienced patients burdened by disease progression and treatment switches may result in increased HCRU.

Drugs 2024; 84:565-578. [PMID: 38630365 PMCID: PMC11190018 DOI: 10.1007/s40265-024-02028-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/25/2024] [Indexed: 06/22/2024]
Abstract
BACKGROUND AND OBJECTIVE The most recently approved biologics for moderate-to-severe psoriasis are the interleukin (IL)-17 and IL-23 inhibitors. Drug survival is a frequently used outcome to assess drug performance in practice. An overview of the available drug survival studies regarding IL-17 and IL-23 inhibitors is lacking. Therefore, our objective was to assess the drug survival of IL-17 and IL-23 inhibitors for psoriasis. METHODS A search of PubMed, Embase, Cochrane Library and Web of Science was conducted (last search 27 December, 2023). Inclusion criteria were (1) cohort study; (2) patients aged ≥ 18 years with plaque psoriasis; and (3) evaluation of drug survival of at least one of the IL-17 and IL-23 inhibitors. Exclusion criteria were: primary focus on patients with psoriatic arthritis, fewer than ten study subjects and another language than English. The Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline was followed. Survival probabilities at monthly intervals were extracted from Kaplan-Meier curves using a semi-automated tool. Data were pooled using a non-parametric random-effects model to retrieve distribution-free summary survival curves. Summary drug survival curves were constructed per biologic for different discontinuation reasons: overall, ineffectiveness and adverse events, and split for the effect modifier biologic naivety. Results were analysed separately for registry/electronic health record data and for pharmacy/claims data. RESULTS A total of 69 studies aggregating drug survival outcomes of 48,704 patients on secukinumab, ixekizumab, brodalumab, guselkumab, risankizumab, and tildrakizumab were included. Summary drug survival estimates of registry/electronic health record studies for overall, ineffectiveness and adverse event related drug survival were high (all point estimates ≥ 0.8 at year 1) for included biologics, with highest estimates for guselkumab and risankizumab. All estimates for drug survival were higher in biologic naive than in experienced patients. Estimates of pharmacy/claims databases were substantially lower than estimates from the primary analyses based on registry/electronic health record data. CONCLUSIONS This meta-analysis showed that the investigated IL-17 and IL-23 inhibitors had high drug survival rates, with highest rates for guselkumab and risankizumab drug survival. We showed that effect modifiers such as biologic naivety, and the source of data used (registry/electronic health record data vs pharmacy/claims databases) is relevant when interpreting drug survival studies.

J Dermatol 2024; 51:210-222. [PMID: 38031882 DOI: 10.1111/1346-8138.17038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 09/28/2023] [Accepted: 10/29/2023] [Indexed: 12/01/2023]
Abstract
Plaque psoriasis (PsO) is a chronic immune-mediated inflammatory disease with skin lesions accompanied by an inflammation-related comorbidity risk. The development of various oral drugs and biologics for PsO has provided increasing systemic treatment options for patients with PsO, and the guidance regarding the use of biologics and PsO treatment schemes are widespread in Japan. However, no comprehensive guidelines regarding systemic drug use are available, and the current treatment patterns of systemic drugs for PsO in Japan remain unclear. We conducted a retrospective chart review to clarify the current treatment patterns of systemic drugs for PsO. We enrolled 114 patients who started systemic drugs for PsO between January 2017 and December 2020 at four institutes, with a mean follow-up of 37.2 months. The mean disease duration was 7.8 (standard deviation 9.5) years at the systemic drug initiation. Of all the patients, 78.1% started with oral drugs (phosphodiesterase [PDE] 4 inhibitors 56.1%. calcineurin inhibitors 14.0%. vitamin A derivatives 7.9%), whereas 21.9% started with biologics (interleukin [IL]-17 inhibitors 9.6%. tumor necrosis factor inhibitors 7.0%. IL-23 inhibitors 3.5%. IL-12/23 inhibitors 1.8%). Oral drugs had shorter drug persistence than biologics: the 12-month persistence of the oral drugs vitamin A derivative, calcineurin inhibitor, and PDE4 inhibitor, was 35.5%, 25.8%, and 60.1%, respectively, compared with that of the biologics IL-23 and IL-17 inhibitors, which was 85.6% and 84.7%, respectively. During the study period, the incidence of treatment changes was 59.1/100 patient-years. Lack of efficacy was the most common reason for treatment changes from monotherapy (34.1%). This retrospective medical chart review allowed us to understand the real-world, long-term treatment patterns of systemic drugs for PsO and the relationships between the reasons for treatment changes and subsequent treatment selection, indicating that there is still room for improvement in the appropriate use of systemic drugs for PsO in Japan.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Psoriasis, an immune system disorder, is a chronic relapsing disease that cannot be cured. Chinese herbal medicine is gradually considered a promising alternative treatment for psoriasis due to its multiple effects, ability to target multiple pathways and lower toxicity. Qingre Lishi Decoction (QRLSD) is effective in clinical treatment. However, its related molecular mechanism remains to be elucidated. AIM OF THE STUDY The purpose of this research was to investigate the therapeutic impacts of Qingre Lishi Decoction on the murine model of psoriasis-like skin lesions induced by imiquimod and to reveal the underlying mechanisms. MATERIALS AND METHODS First, QRLSD was orally administered to evaluate its efficacy in an imiquimod (IMQ)-induced psoriasis mouse model. Further, UPLC-Q-TOF/MS was used to analyze the compounds of QRLSD. To investigate the mechanism and main targets of QRLSD for treating psoriasis, network pharmacology and molecular docking methods were utilized. Finally, To further confirm the anti-psoriasis target, dendritic cells derived from bone marrow (BMDCs) were cultured in vitro. RESULTS In vivo experiments found that QRLSD could regulate the ratio of dendritic cells, Treg cells, and Th17 cells in the body and inhibit inflammation and keratinocyte proliferation in psoriasis-like skin lesions. Further analysis showed that the p38-MAPK pathway is one of its main signaling pathways. In vitro experiments confirmed that QRLSD suppressed the maturation and activation of BMDCs via the p38-MAPK signaling pathway. CONCLUSIONS This study suggests that Qingre Lishi Decoction has the promise to be an effective formula for treating psoriasis through the p38-MAPK pathway, which can help break through the current limitations of psoriasis in clinical treatment.

Abstract
INTRODUCTION Patients with moderate-to-severe psoriasis (PsO) treated with interleukin (IL)-inhibitors may require treatment modification to achieve disease control. This study evaluated discontinuation and switching of IL-inhibitors for PsO patients in Japan. METHODS Japan Medical Data Center claims (1/2005-5/2022) were used to identify patients with PsO diagnosis preceding a first IL-inhibitor claim (index date) with ≥ 6 months of eligibility prior. Treatment switch (claim for another biologic) and discontinuation (gap in care ≥ 150% of the days' supply of the preceding prescription) were assessed up to 24 months following initiation. Censored Kaplan-Meier time-to-event analyses calculated rates, and Cox proportional hazards models estimated hazard ratios (HRs) adjusting for baseline characteristics. RESULTS The study included 1481 unique patients treated with brodalumab (BRO; n = 159), guselkumab (GUS; n = 360), ixekizumab (IXE; n = 279), risankizumab (RIS; n = 327), secukinumab (SEC; n = 366), tildrakizumab (n = 40; excluded due to limited data), and ustekinumab (UST; n = 262). At 12/24 months, 25.9%/38.6% of patients overall had discontinued their index IL-inhibitor and 13.5%/21.2% had switched to another biologic. Discontinuation at 12/24 months was lowest for RIS (11.2%/17.4%), followed by UST (17.9%/32.2%), IXE (27.0%/37.0%), GUS (29.8%/43.0%), SEC (35.6%/53.8%), and BRO (37.2%/47.2%). Switching showed a similar trend: RIS (5.7%/10.7%), UST (11.2%/19.9%), SEC (14.7%/25.7%), IXE (14.8%/21.5%), GUS (16.9%/23.2%), and BRO (19.7%/26.8%). HRs of discontinuation relative to RIS were 2.07 for UST, 2.59 for IXE, 2.70 for GUS, 3.65 for BRO, and 3.69 for SEC (all P ≤ 0.001). HRs of switching relative to RIS were 2.05 for IXE, 2.45 for GUS, 2.67 for SEC, 2.73 for UST, and 2.77 for BRO (all P ≤ 0.01). CONCLUSION Treatment modification of IL-inhibitors for PsO was commonly observed and could indicate insufficient disease control and/or incremental economic burden. Discontinuation and switching rates were lowest for RIS regardless of time point and adjustment for patient characteristics.

Abstract
Psoriasis is a chronic, immune-mediated inflammatory skin disease with a high negative impact on patient's quality of life. Secukinumab, the first interleukin 17A inhibitor, has been used for the systemic treatment of psoriasis, but its long-term, real-world retention rates in Japan have not been fully investigated. In this multicenter, noninterventional, retrospective chart review study, the retention rate of secukinumab and its effectiveness among patients with psoriasis in Japan was evaluated up to 5 years. Data of patients who received secukinumab after December 26, 2014, were collected from medical charts obtained from seven sites, all certified for biologics use by the Japanese Dermatological Association. Patient characteristics, secukinumab retention, factors affecting secukinumab retention, reason for drug discontinuation, and effectiveness data were collected. The primary end point was secukinumab retention rate at week 52. A total of 123 patients were included in the analysis. Of these, 27 patients discontinued secukinumab by week 52, yielding a 78.0% (95% confidence interval, 69.6-84.4) retention rate at week 52. For patients whose Psoriasis Area and Severity Index (PASI) score was available, mean ± standard deviation PASI at baseline and at week 52 were 9.21 ± 7.37 and 1.4 ± 2.6, respectively. During the entire study period, "insufficient response" was the most common reason for discontinuation, and "history of biologics use" was a factor significantly associated with secukinumab discontinuation (hazard ratio, 1.72; p = 0.018). This study demonstrates the real-world retention rate and effectiveness of secukinumab in patients with psoriasis in Japan for up to 5 years and provides clinical insights into psoriasis treatment strategies.

Abstract
Psoriasis, a chronic autoimmune disease characterized by the hyperproliferation of keratinocytes in the epidermis and parakeratosis, significantly impacts quality of life. Interleukin (IL)- 17A dominates the pathogenesis of psoriasis and facilitates reactive oxygen species (ROS) accumulation, which exacerbates local psoriatic lesions. Biologic treatment provides remarkable clinical efficacy, but its high cost and unignorable side effects limit its applications. 3 H-1,2-Dithiole-3-thione (D3T) possesses compelling antioxidative capacities against several diseases through the nuclear factor erythroid 2-related factor 2 (Nrf2) cascade. Hence, we aimed to evaluate the effect and mechanism of D3T in psoriasis. We found that D3T attenuates skin thickening and scaling by inhibiting IL-17A-secreting γδT cells in imiquimod (IMQ)-induced psoriatic mice. Interleukin-17A markedly enhanced IL-6 and IL-8 expression, lipid peroxidation, the contents of nitric oxide and hydrogen peroxide, oxidative phosphorylation and the MAPK/NF-κB pathways in keratinocytes. IL-17A also inhibited the Nrf2-NQO1-HO-1 axis and the activities of superoxide dismutase and glutathione peroxidase. D3T significantly reversed these parameters in IL-17A-treated keratinocytes. ML-385, a Nrf2 neutralizer, failed to improve D3T-induced anti-inflammatory and antioxidative effects in IL-17A-treated keratinocytes. We conclude that targeting Nrf2 with D3T to diminish oxidative and inflammatory damage in keratinocytes may attenuate psoriasis.

Abstract
The real-world treatment landscape for patients with moderate-to-severe psoriasis receiving systemic therapies in Japan is not well understood. This study describes the demographic and clinical characteristics, treatment patterns, healthcare resource utilization, and psoriasis-associated costs in these patients. This retrospective observational study used data from the Japan Medical Data Center database between January 2016 and December 2020. Eligible patients had a confirmed diagnosis of psoriasis, ≥1 claim for a systemic treatment of interest, medical history for ≥6 months, and follow-up data for ≥12 months. Systemic therapies comprised biologics (tumor necrosis factor and interleukin inhibitors) and oral treatments (a phosphodiesterase-4 inhibitor, immunosuppressants, and vitamin A). Patient demographics and clinical characteristics, treatment patterns, healthcare resource utilization, and costs were evaluated. The study identified 1770 patients satisfying all inclusion criteria. The mean age was 49.0 years, with 68% of patients aged 20-54 years. Overall, 90.6% and 9.4% of patients received oral medications and biologics as index treatment, respectively. Treatment patterns, healthcare resource utilization, and costs were assessed for treatments received by ≥20 patients (n = 1730). During the 12-month follow-up period, 1102/1730 patients (63.7%) discontinued index treatment, of whom 9.9% switched to alternative systemic treatments. The persistence rate was ≥70% for most biologics and <50% for oral systemic treatments. All 1730 patients had ≥1 all-cause outpatient visit (2.0 visits per person per month) and hospitalization frequency was ≤0.01 per person per month. Persistent patients incurred inflation-adjusted costs of Japanese Yen (JPY) 88 667 per person per month. Treatment switching was associated with an increase in total cost: JPY 128 039 per person per month after switching versus JPY 117 504 before switching. This study of Japanese patients with moderate-to-severe psoriasis demonstrated low persistence, high discontinuation, and low rates of treatment switching with systemic therapies. Switching was associated with increased total cost. These results indicate unmet needs for new treatments.

Abstract
Psoriasis (PSO), an immune-mediated chronic inflammatory skin disease, has seriously affected the quality of patients' life. It is urgent to find effective medicines with lower costs and less side effects. Baicalin (HQG) is the main bioactive substance from Scutellaria baicalensis with effects of anti-inflammation and immunoregulation. Herein, we explored the effect of oral HQG treating PSO and its potential mechanism. Firstly, network pharmacology was used to predict that HQG may act on Estrogen, TNF-alpha (tumor necrosis factor, TNF), interleukin-17 (IL-17) signaling pathways and Th17 cell differentiation, especially the key targets including TNF, Proto-oncogene tyrosine-protein kinase Src, Peroxisome proliferator-activated receptor gamma and Matrix metalloproteinase-9. Imiquimod (IMQ)-induced mice were then used to study the effects of HQG treating PSO. HQG could significantly ameliorate the skin lesions, decrease the level of inflammatory factors and inhibit Th1/Th17 cell differentiation in IMQ-induced mice. Finally, transcriptome analysis of skin lesions integrated with the prediction of network pharmacology further demonstrated that the potential mechanism may be associated with suppressing Wnt signaling pathway and inhibiting Th17/IL-17 axis by activating PPARγ. In conclusion, this study suggested that HQG may be a promising agent for further studies in the search for therapeutic strategies to treat PSO in the future.

Abstract
Introduction Molecular targeted therapies (MTTs) cause skin disorders in patients with cancer, and moisturizers are useful treatments; however, their actual use and costs are unknown. Our purpose was to examine the use and costs of moisturizers prescribed for xerosis (asteatosis) in patients with cancer treated with MTTs. Methods We used data from a Japanese hospital-based claims database. The index date was the first date of MTT prescription from October 2011 to April 2018 (selection period), and the follow-up period was 1 year from the index date. Patients treated with MTTs during the selection period and who were not prescribed moisturizers in the 6 months before the index date were included as the study cohort. Timing, duration, amount, and costs of the prescribed moisturizers and total medical costs were analyzed. Results Among the 78,190 patients in the study cohort, 27,906 patients (35.7%) were prescribed moisturizers during follow-up. Moisturizer prescription timing, duration, and volume were inconsistent. The average annual total medical costs for treating patients with MTT who were prescribed moisturizers was JPY 6.165 million (USD 53,797) per patient, and the moisturizer costs were JPY 6033 (USD 53). The number of patients who used moisturizers showed an increasing trend. Conclusion No consistent patterns were observed for the timing or duration of moisturizer use, which suggests various developmental patterns of skin disorders. Furthermore, medical costs for moisturizers accounted for only a small proportion of the total medical costs required for cancer treatment.

Abstract
Despite the large number of biologics currently available for moderate-to-severe psoriasis, poor adherence and persistence to therapy represent the main issues for both the clinical and economic management of psoriasis. However, the data about adherence and persistence to biologics in psoriasis patients are conflicting. Our aim was to produce summary estimates of adherence and persistence to biologics in adult patients with psoriasis. We performed a systematic review and meta-analysis of observational studies, searching two databases (PubMed and Embase). Sixty-two records met the inclusion criteria, and a meta-analysis was conducted on fifty-five studies. Overall, the proportion of adherent and persistent patients to biological therapy was 0.61 (95% confidence interval: 0.48–0.73) and 0.63 (0.57–0.68), respectively. The highest proportions were found for ustekinumab, while the lowest ones were found for etanercept. The proportions of adherence and persistence to biological drugs in psoriasis patients are sub-optimal. Notably, both proportions largely differ between drugs, suggesting that a more rational use of biologics might ensure better management of psoriasis.

Abstract
Infliximab (IFX) has contributed to the treatment of several chronic inflammatory diseases, including Crohn's disease (CD), ulcerative colitis (UC), psoriasis (Pso), and rheumatoid arthritis (RA). However, the loss of response in some patients with long-term IFX therapy has been a major problem. Randomized controlled trials (RCTs) are limited in their short duration and lack of generalizability to the real-world population. We aimed to describe the persistence rates of IFX therapy to estimate its long-term effectiveness in clinical practice. Claims data from the Japan Medical Data Center database from January 2005 to June 2017 were used. The study population was identified based on the International Classification of Diseases, 10th Revision and the Anatomical Therapeutic Chemical Classification System. The 5-year persistence rates of IFX therapy were estimated using the Kaplan-Meier method. Overall, 281, 235, 41, and 222 patients with CD, UC, Pso, and RA, respectively, were selected. The 5-year persistence rates for IFX claims were 62.9, 38.9, 22.1, and 28.1% in patients with CD, UC, Pso, and RA, respectively. Patients with CD and UC administered IFX beyond the median dose had higher persistence rates. In patients with RA, female sex and no prior use of other biologics were associated with longer persistence. In conclusion, IFX persistence rates differed across chronic inflammatory diseases, which did not correspond to the results of the major RCTs. Factors associated with longer IFX persistence were identified in each disease group. Our findings may provide useful information to facilitate the proper use of IFX.

Abstract
Introduction Biologic agents are used in patients with severe psoriasis who have not adequately responded to existing conventional systemic therapies. However, only a limited number of medical institutions in Japan are approved to use them, and their relatively high cost represents a substantial burden to patients. Apremilast is an oral phosphodiesterase-4 inhibitor approved in Japan for the treatment of psoriasis vulgaris in adult patients with an inadequate response to topical therapies and psoriatic arthritis in adult patients with active disease. To date, a large-scale real-world study of treatment patterns and costs associated with apremilast in Japan has not been conducted. The objective of this study was to assess whether apremilast can prolong time to first biologic therapy use and decrease total medical cost. Methods Using the Medical Data Vision hospital-based claims database, 506 psoriasis patients were propensity score matched and analyzed (apremilast: n = 253; non-apremilast: n = 253). Results The incidence rate of first biologic therapy use per 1000 patient-years was significantly lower in the apremilast group than in the non-apremilast group (30.3 vs. 107.6; P < 0.001), and the total medical costs per month were significantly lower in the apremilast group than in the non-apremilast group (76,594 yen/month vs. 102,411 yen/month, P < 0.001). In a sensitivity analysis of a propensity-score-matched subset of eligible patients prescribed biologics during the follow-up period (apremilast: n = 14; non-apremilast: n = 14), the incidence of first biologic therapy use was 2,797.6 per 1000 patient-years (95% CI: 1,656.9, 4,723.6) in the non-apremilast group and 856.1 per 1000 patient-years (95% CI: 507.0, 1,445.5) in the apremilast group. Conclusion These results suggest that apremilast prolongs the time to first biologic therapy use in patients with psoriasis, thereby reducing the total medical cost and decreasing the economic burden on patients.

Abstract
Real‐world and long‐term data on biologic treatment changes – including switching, discontinuation, dose escalation, and interval change (both increasing and decreasing) – are required to understand treatment patterns for psoriasis (PsO) in Canada. The study objectives were to evaluate the time to first biologic treatment change and to document these changes in Canadian patients with moderate‐to‐severe chronic plaque PsO. Charts from 13 Canadian sites were queried retrospectively (2005–2019); a period covering all biologic classes commonly used for PsO in Canada. Included were patients diagnosed with, and currently using biologics for, moderate‐to‐severe chronic plaque PsO. Time to first treatment change, nature of treatment change, number of lines of treatment, proportion of patients on each drug, and drug survival were collected. Based on 1149 medical charts, adalimumab had the longest time to first treatment change (49.3 months; 95% confidence interval, 37.4–67.4). Approximately half of the patients had a treatment change, and nearly 75% of these changes were either an interval change or a biologic switch. Lack of efficacy was the most prevalent primary reason for biologic switch (67.3%), whereas 6.7% of patients switched due to adverse events. Drug survival for etanercept and infliximab was approximately twice as long for patients who had dose optimization (i.e., dose escalation or interval change) than patients without dose optimization. The survival curve of adalimumab was similar to the one of ustekinumab after 48 months of treatment, showing approximately 60% of patients remaining on treatment after 132 months, with or without dose optimization. Assessing treatment patterns of all commonly used biologics for moderate‐to‐severe chronic plaque PsO in Canada between 2005 and 2019 showed that approximately half of the patients required a treatment change (mainly interval change or biologic switch) while the other half remained on treatment.

Abstract
Background Real-world big data studies using health insurance claims databases require extraction algorithms to accurately identify target population and outcome. However, no algorithm for Crohn’s disease (CD) has yet been validated. In this study we aim to develop an algorithm for identifying CD using the claims data of the insurance system. Methods A single-center retrospective study to develop a CD extraction algorithm from insurance claims data was conducted. Patients visiting the Kitasato University Kitasato Institute Hospital between January 2015–February 2019 were enrolled, and data were extracted according to inclusion criteria combining the Tenth Revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) diagnosis codes with or without prescription or surgical codes. Hundred cases that met each inclusion criterion were randomly sampled and positive predictive values (PPVs) were calculated according to the diagnosis in the medical chart. Of all cases, 20% were reviewed in duplicate, and the inter-observer agreement (Kappa) was also calculated. Results From the 82,898 enrolled, 255 cases were extracted by diagnosis code alone, 197 by the combination of diagnosis and prescription codes, and 197 by the combination of diagnosis codes and prescription or surgical codes. The PPV for confirmed CD cases was 83% by diagnosis codes alone, but improved to 97% by combining with prescription codes. The inter-observer agreement was 0.9903. Conclusions Single ICD-code alone was insufficient to define CD; however, the algorithm that combined diagnosis codes with prescription codes indicated a sufficiently high PPV and will enable outcome-based research on CD using the Japanese claims database.

Abstract
Background Little is known about the effectiveness and drug survival associated with apremilast under real-world conditions. Objective To investigate the influence of patient and disease characteristics on drug survival associated with apremilast and to elucidate clinical effectiveness with regard to the psoriasis area and severity index (PASI) reduction. Methods This was an observational, retrospective, multicenter analysis from the Austrian Psoriasis Registry. Results Data from 367 patients were eligible for analysis. The 12-month drug survival rate associated with apremilast (ie, the proportion of patients on the drug) was 57.3% and decreased significantly in patients younger than 40 years (relative hazard ratio = 1.49, P = .007918). Sex; concomitant arthritis; previous biologic therapy; obesity; and palmoplantar, scalp, nail, and intertriginous involvement did not significantly affect drug survival. At 12 months, the response rates in patients receiving apremilast per protocol with a PASI of 50, 75, 90, and 100 were 80.0%, 56.4%, 38.2%, and 22.7%, respectively. Limitations Inclusion of a substantial number of patients with no record of absolute PASI at study entry and lack of PASI reduction follow-up data of 103 patients (28.1%) after starting apremilast treatment. Conclusion Apremilast is a robust antipsoriatic drug for which the drug survival is not strongly influenced by most patient- or disease-related factors except age. Drug survival is significantly shorter in patients younger than 40 years.

Abstract
Biologics are recommended in Japan to treat moderate to severe Crohn’s Disease (CD). Although CD is associated with high direct costs in Japan, updated information after ustekinumab’s approval is unavailable. We aimed to evaluate the healthcare resource utilization (HRU) and associated direct costs from the payer’s perspective in Japan. Claims data (2010–2018) were retrospectively analyzed to identify patients with CD. HRU and associated costs were evaluated for 12 months before and after biologic initiation and followed-up till 36 months post-initiation. Outcomes were reported using descriptive statistics. Among the included patients (n = 3,496), 1,783 were on biologics and 1,713 were on non-biologics. Mean (SD) age was 36.4 (13.2) years and patients were predominantly male (76.1%). Patients aged 18–39 years were affected with CD the most (55.3%). Biologic initiation was associated with a reduction in inpatient stay, length of stay, outpatient visits, and associated costs; and an increase in pharmacy costs and total costs after 12 months. Extended follow-up showed a decreasing trend in HRU and costs till 24 months but an increase after 36 months. These findings demonstrated reduction in clinical burden and slight increase in economic burden with biologics. However, indirect costs also need to be evaluated.

Abstract
Psoriasis is a most common chronic autoimmune-arbitrated cutaneous inflammatory skin disorder by unclear pathogenesis. In this current study we demonstrated the effect of galangin (GAL) on imiquimod (IMQ)-induced psoriasis-like skin inflammation and decipher its possible protective mechanism which has not been investigated. The in vivo results revealed that GAL at 1% w/w and 2% w/w for six consecutive days markedly reduced IMQ-induced PASI scoring, skin, ear thickness, hematological markers, levels of nitrites, TBARS, MPO, histopathological, as well modulated the protein levels of pro-inflammatory mediators of COX-2, iNOS, NF-κB pathway and pro-inflammatory cytokines IL-17, IL-23, IL-1β in the skin and also IL-6, TNF-α in both skin and serum. Besides, GAL restored the levels of antioxidants markers such as SOD, CAT, GST, GSH, GR and Vit-C, anti-inflammatory cytokine of IL-10, and the protein levels of Nrf2/HO-1 in the skin compared to the IMQ group. Finally, our study demonstrates that GAL exerted its protective effect by up-regulating the anti-inflammatory and the antioxidant markers against psoriasis pre-clinical models indicating its potency for treating psoriasis in humans.

Abstract
Background Psoriasis is a chronic autoimmune skin disease characterized by hyperproliferation of keratinocytes. Wide treatment options used to treat psoriasis is associated with various adverse effects. To overcome this nanoformulation is prepared. Selenium is an essential trace element and plays major role in oxidation reduction system. Toxicity and stability limits the applications of selenium. Toxicity can be reduced and stabilized upon preparation into nanoparticles. Results Selenium nanoparticles (SeNPs) exhibit potent apoptosis through the generation of reactive oxygen species (ROS) with cell cycle arrest. SeNPs topical gel application produced significant attenuation of psoriatic severity with the abrogation of acanthosis and splenomegaly. SeNPs reduced the phosphorylation and expressions of MAPKs, STAT3, GSK-3β, Akt along with PCNA, Ki67, and cyclin-D1. Conclusion SeNPs inhibit various inflammation and proliferation mediated pathways and could be an ideal candidate for psoriasis therapy. Materials and methods SeNPs were characterized and various techniques were used to determine apoptosis and other molecular mechanisms. In vivo studies were performed by inducing psoriasis with imiquimod (IMQ). SeNPs were administered via topical route.

Abstract
OBJECTIVE Assess patient characteristics, real-world treatment patterns, and health care resource utilization (HCRU) among patients with psoriatic arthritis (PsA) in Japan. METHODS Patients diagnosed with PsA from April 2009 through July 2017 were identified from the Medical Data Vision database. Patient characteristics, treatment patterns, and HCRU were evaluated for these patients. RESULTS A total of 639 patients met inclusion criteria and were included in the analysis for patients with a PsA diagnosis. Over 12 months following diagnosis, patients received oral NSAIDs (61.7%), conventional synthetic disease-modifying antirheumatic drugs (DMARDs) (55.1%), corticosteroids (35.1%), topical NSAIDs (34.0%), adalimumab (14.7%), infliximab (9.7%), secukinumab (5.0%), ustekinumab (4.5%), ixekizumab (1.6%), and golimumab (1.6%). A total of 227 (35.5%) patients initiated biologic DMARDs (bDMARDs) over the median 25.2 months of study follow-up. Compared with the overall group of patients diagnosed with PsA, patients who initiated bDMARDs had higher median total per-patient health care costs ($27,772 vs. $11,316), lower median per-patient hospitalization costs ($31,164 vs. $39,359), and fewer median hospital days per admission (8.0 vs. 12.0 days). CONCLUSION This study presents knowledge of the current state of patient characteristics, treatment patterns, HCRU, and costs among patients with PsA in Japan. Considering the relatively recent guideline recommendations, the preliminary treatment patterns suggest physicians may be following treatment guidelines.

Abstract
INTRODUCTION To investigate drug survival for biologic disease-modifying antirheumatic drugs (bDMARDs) in a real-world cohort of German adult biologic-naïve patients with psoriatic arthritis (PsA). METHODS Claims data for patients with a diagnosis of PsA, a bDMARD claims record (index date) between 1 January 2014 and 31 December 2017, and no bDMARD prescription for 365 days before the index date were retrospectively analyzed. The primary outcomes were the overall and individual bDMARD persistence rates over 12 months. Nonpersistence was defined as a treatment gap exceeding the days of supply plus 60 days or switching to a bDMARD other than the index therapy. Sensitivity analysis was performed, wherein the treatment gap was found to vary depending on the bDMARD regimen. Kaplan-Meier curves were plotted to determine persistence; the log-rank test was used to evaluate differences in the persistence rate. Factors associated with treatment discontinuation were evaluated using Cox regression analysis. RESULTS Among 10,954 patients with a PsA diagnosis, 348 were eligible. The overall bDMARD persistence rate was 57.5%; individual bDMARD persistence rates were 81.3% for ustekinumab, 66.7% for infliximab, and 60.0% for golimumab. The mean (SD) overall persistence with bDMARDs was 289 (103) days; the mean persistence was 334 (72) days for ustekinumab, 309 (82) days for golimumab, and 305 (92) days for infliximab. The main reasons for nonpersistence were switching to another bDMARD (15.8%) and treatment discontinuation (26.7%). Male gender was significantly associated with a lower risk of treatment discontinuation (hazard ratio 0.54, 95% confidence interval 0.39-0.77; P < 0.001). The sensitivity analysis yielded similar results. CONCLUSION The one-year persistence rate for bDMARDs in German PsA patients is modest, although the persistence rate depends on the bDMARD considered.

Abstract
BACKGROUND Obesity is associated with an increased risk of psoriasis. OBJECTIVE In this study, we examined whether body mass index (BMI) is taken into account when choosing first-line biologic therapy for psoriasis. METHODS In this cohort study, we compared obese (BMI ≥30 kg/m2) and non-obese patients for the first-line biologic therapy prescribed, its survival, reasons for discontinuation, therapy optimization, co-prescription of methotrexate and factors associated with long drug survival. RESULTS A total of 931 patients were included: 594 (64%) were male, median age was 46 years (interquartile range 36-56). The most-prescribed biologic agents as first-line treatment were adalimumab (ADA; 42.7%), ustekinumab (UST; 29.9%) and etanercept (ETA; 22.9%); only frequency of infliximab (IFX) prescription differed between groups. Drug survival was significantly shorter for obese than non-obese patients (p < 2.10-4) and was worse for obese than non-obese patients for UST (p = 0.009) and ETA (p = 0.02), with no difference for ADA (p = 0.11). The main reason for discontinuation was primary inefficacy (62%), which was more frequent in obese than non-obese patients. The cumulative incidence of optimization did not significantly differ between the groups, except for ADA (SHR 1.91, 95% CI [1.23-2.96], p = 0.005). On multivariate analysis, risk of discontinuation was associated with only ETA as first-line biologic therapy (HR 1.51, 95% CI 1.04-2.19). CONCLUSION This study highlighted the lack of difference in prescription of first-line biologic treatment, except for IFX, between obese and non-obese patients presenting moderate-to-severe psoriasis. Drug survival in obese patients is shorter, mainly because of inefficacy, than in non-obese patients. This highlights the need for targeted pharmacological studies in obese individuals to find optimal administration schemes.

Long-term efficacy and safety of tildrakizumab in Japanese patients with moderate to severe plaque psoriasis: Results from a 5-year extension of a phase 3 study (reSURFACE 1). J Dermatol 2021; 48:844-852.

Abstract
The three part, double‐blind, randomized, controlled reSURFACE 1 trial and extension study (NCT01722331) evaluated efficacy and safety of tildrakizumab in adults with moderate to severe plaque psoriasis. Patients with ≥50% improvement from baseline in Psoriasis Area and Severity Index (PASI 50) following treatment with tildrakizumab 100 mg (TIL100) or 200 mg (TIL200) could enter the optional long‐term extension study and continue treatment at the same dose for an additional 192 weeks. This subgroup analysis assessed the long‐term efficacy and safety of tildrakizumab treatment for Japanese patients enrolled in reSURFACE 1 for up to 5 years of treatment. The primary efficacy outcomes were the proportions of patients who maintained PASI 75 and Physician Global Assessment (PGA) clear or minimal with ≥2‐grade reduction from baseline (PGA 0/1) from base study week 64 to extension week 192. Secondary outcomes were the proportion of patients who maintained PASI 90/100 from base study week 64 to extension week 192. Adverse events (AEs) were monitored throughout the study and for up to 20 weeks after the last study visit. Of the 120 Japanese patients who entered the reSURFACE 1 extension study, 43 (79.6%) patients receiving tildrakizumab 100 mg and 58 (87.9%) patients receiving tildrakizumab 200 mg completed the extension study. Of all Japanese patients with PASI 75/90/100 and PGA 0/1 at week 64, 85%/88% receiving TIL100/TIL200 maintained PASI 75, 70%/96% maintained PASI 90, 63%/67% maintained PASI 100, and 68%/72% maintained PGA 0/1 at extension week 192. AEs led to discontinuation in 1.7 patients per 100 patient‐years (P100PY) receiving tildrakizumab 100 mg and 0.8 P100PY receiving tildrakizumab 200 mg. Incidences of severe infections, malignancies, confirmed major adverse cardiac events, and hypersensitivity reactions were low in both treatment groups. Through 5 years of treatment, tildrakizumab maintained efficacy and was well tolerated with low rates of AEs of special interest.

Abstract
Psoriasis is a chronic inflammatory skin disease that affects approximately 2% of worldwide population, and causing long-term troubles to the patients. Therefore, it is urgent to develop safe and effective therapeutic drugs. Catalpol is a natural iridoid glucoside, that has several remarkable pharmacological effects, however, whether catalpol can alleviated psoriasis has not been explored. The goal of the present work is to study the role of catalpol in psoriasis in vivo and in vitro. Imiquimod-induced psoriasis-like mice were applied with different concentrations of catalpol for 8 consecutive days. The severity degree of psoriasis was estimated and the skin pathological changes were detected by H&E staining. Also, TNF-α-stimulated keratinocytes were treated with different concentrations of catalpol, then the oxidative stress and inflammation factors, as well as the expression of SIRT1 and activation of NF-kB and MAPK pathways were measured. The results showed that catalpol reduced the erythema, scaling, ear thickness, and changed pathological phenotypes in the lesioned skin region in mice. Treatment with catalpol significantly suppressed the oxidative stress and inflammatory reactions in vivo and in vitro, as reflected by the decreased secretion or expression of oxidative stress indicators and proinflammatory factors. Furthermore, the SIRT1 was up-regulated and the NF-κB and MAPKs signaling pathways were suppressed by the treatment of catalpol in vivo and in vitro. In summary, our data suggested that catalpol may have a therapeutic property of psoriasis by ameliorating oxidative stress and inflammation partly through SIRT1 mediated suppression of NF-κB and MAPKs pathways.

Abstract
Background Drug survival rates reflect efficacy and safety and may be influenced by the availability of alternative treatment options. Little is known about time‐dependent drug survival in psoriasis and the effect of increasing numbers of biologic treatment options. Objectives To determine whether drug survival is influenced by the availability of treatment options and by factors such as gender, psoriatic arthritis or previous biologic treatment. Methods This observational, retrospective, multicentre cohort study analysed data from patients registered in the Austrian Psoriasis Registry (PsoRA) who were treated with biologics between 1 January 2015 and 30 November 2019. Results A total of 1572 patients who received 1848 treatment cycles were included in this analysis. The highest long‐term Psoriasis Area and Severity Index improvement was observed after treatment with ixekizumab, followed by ustekinumab and secukinumab, adalimumab and etanercept. Overall, ustekinumab surpassed all other biologics in drug survival up to 48 months. However, when adjusted for biologic naïvety, its superiority vanished and drug survival rates were similar for ixekizumab (91·6%), secukinumab (90·2%) and ustekinumab (92·8%), all of them superior to adalimumab (76·5%) and etanercept (71·9%) at 12 months and beyond. Besides biologic non‐naïvety (2·10, P < 0·001), the introduction of a new drug such as secukinumab or ixekizumab (relative hazard ratio 1·6, P = 0·001) and female gender (1·50, P = 0·019) increased the risk of treatment discontinuation overall, whereas psoriatic arthritis did not (1·12, P = 0·21). Conclusions The time‐dependent availability of drugs should be considered when analysing and comparing drug survival. Previous biologic exposure significantly influences drug survival. Women are more likely to stop treatment.
What is already known about this topic?
Female gender and previous biologic exposure have been discussed as predictors for decreased drug survival in patients with psoriasis, but it remains unknown whether a time‐dependent increased availability of treatment options alters biologic drug survival.
What does this study add?
The increased availability of alternative biologic treatments over time leads to an elevated risk for treatment discontinuation overall; therefore, drug survival analysis has to be time adjusted. Moreover, the study reveals that the impact of previous biologic treatment on drug survival is tremendous and confirms worse drug survival in female patients.

Abstract
Aim: To describe the characteristics and medication treatment patterns, healthcare resource utilization (HRU), and associated costs in Japanese patients with systemic lupus erythematosus (SLE).Methods: Claims data from the Japan Medical Data Center (JMDC) database were used to identify patients with SLE-related claims from 2010 to 2017. Algorithms were developed to retrospectively categorize patients by disease severity, treatment experience, and SLE-related manifestations such as lupus nephritis and central nervous system lupus. Descriptive and multivariate analyses were used to describe treatment pattern and estimate HRU and associated costs for the SLE cohort overall and by disease severity and complications.Results: Among 4,733 eligible patients, 2,072 (43.8%) were treatment naïve, 2,214 (46.8%) were previously treated for SLE, and 447 (9.4%) did not receive any treatment. Mean (SD) age of the total SLE cohort was 45.2 (13.1) years and mean (SD) follow-up duration was 1,137.3 (758.0) d. Based on disease severity, 1,383 (29.2%) patients had mild, 2,619 (55.3%) patients had moderate, and 731 (15.4%) patients had severe SLE. Patients on glucocorticoids (both oral and parenteral) received add-on medications the most (35.5%, p < .001). Mean annual cost per SLE patient in the post-index period, inclusive of hospitalizations, outpatient visits, and pharmacy was ¥436,836; ¥1,010,772; and ¥2,136,780 for patients with mild, moderate, and severe SLE, respectively.Limitations: The database only captured information on patients up to 75 years of age. Due to the nature of the database, biases regarding conditions that attribute to the spectrum of SLE severity, flare incidences, or individual physical status cannot be ruled out.Conclusions: This study describes the treatment patterns and economic burden experienced by Japanese patients with SLE. The results highlight an unmet need to derive better treatment strategies for patients with SLE to effectively address the disease burden in Japan.

Abstract
PURPOSE Studies of medication persistence in plaque psoriasis have shown inconsistent results, likely due to differing definitions of nonpersistence and of the permissible gap between refills. Also, medication persistence information for two recently approved drugs, apremilast and ixekizumab, is limited. METHODS We use the Truven Health MarketScan claims database to assess persistence for six drugs: adalimumab, apremilast, etanercept, ixekizumab, secukinumab, and ustekinumab. We define the permissible gap in three ways: 150 days for ustekinumab and 90 days for all other drugs (150/90 model); 120 days for all drugs (120 model); and twice the days' supply for all drugs (days' supply model). To estimate unadjusted persistence, we use Kaplan-Meier curves, and a proportional hazards model to estimate the adjusted risk of non-persistence. RESULTS Ustekinumab is most sensitive to changes in the definition of permissible gap, likely because of its longer maintenance dosing interval. Among targeted drug-experienced patients using ustekinumab, median persistence is 358 days (95% confidence interval: 343-371) in the 150/90 model and 189 days (179-199) in the days' supply model. Among targeted drug-experienced patients, median persistence in the days' supply model is longest for ixekizumab and secukinumab at 252 (217-301) and 222 (210-244) days, respectively. We also find that adjusted risk of nonpersistence increases by approximately 1% per year at treatment start. CONCLUSION The definition of permissible gap meaningfully changes both absolute and ordinal estimates of medication persistence. Each definition has unique limitations, which should be considered when interpreting persistence data.

Abstract
INTRODUCTION Our aim was to study drug survival and associated costs of biologic treatment in a German real-world cohort of biologic-naïve psoriasis patients. METHODS We utilized a German claims database base with 3,682,561 enrolled patients between 2001 and 2015. Kaplan-Meier curves were plotted to show the persistence of different biologics. To determine factors that influence persistence, a Cox regression analysis was performed. In addition, associated costs were calculated 12 months before and after treatment start with biologics. RESULTS Among 75,561 patients with a diagnosis of psoriasis, we identified 347 patients who received a biologic; 176 of them were biologic-naïve prior to initiating therapy. Overall, the 1-year persistence rate was 56%. The highest persistence rate was observed for ustekinumab (80%). Younger patients, and those with a high comorbidity index, had a numerically increased risk of treatment discontinuation. However, parameter values were not statistically significant. While the overall costs after treatment start increased due to the acquisition costs of biologics, we found a strong decrease (- 41%) in sick leave after treatment with biologics had been initiated. CONCLUSION Observed drug survival rates in this real-world setting were relatively low. In line with previous studies, ustekinumab had a higher persistence rate than other biologics.

Abstract
BACKGROUND With progress being made in the treatment of psoriasis, a variety of clinical research and treatment options are being pursued. This study used a discrete choice experiment (DCE) to estimate treatment characteristic preferences for both patients and physicians in Japan. Subgroup analysis was also applied in order to examine differences within the range of patients and within the range of physicians. METHODS The DCE was developed with the input of clinical experts in the treatment of psoriasis to ensure inclusion of the most relevant attributes at appropriate levels in a way that is understandable to both physicians and patients. The study was conducted on parallel samples of Japanese physicians (n = 161) and Japanese psoriasis patients (n = 306) through an online panel. For each sample, a conditional logit statistical model and subgroup analysis were then performed to estimate respondent preferences for treatment attributes. RESULTS The overall findings are that better treatment efficacy as measured by proportion of patients achieving 90% reduction in the Psoriasis Area and Severity Index score (PASI 90), lower risk of adverse events and the availability of a bio-holiday are important decision factors for both patients and physicians. Low injection frequency is less of a priority for both samples. Also, while both groups demonstrate a preference to receive the treatment injections at a clinic by a healthcare professional rather than self-injection at home, this is more pronounced for the patient sample. The physician sample shows considerably more emphasis on the type of injection, though both samples prefer subcutaneous injections to intravenous injections. IMPLICATIONS This study reveals the importance of addressing both clinical effectiveness and process factors in systemic, non-topical psoriasis treatments to gain acceptance by both physicians and patients. As well as efficacy (as measured by PASI 90), which remains a consistent priority in treatment, administration and development of new treatments should also consider process factors such as the mode of administration and possibility for a bio-holiday.

Abstract
Psoriasis is a chronic autoimmune disease affecting skin which may also manifest in nails and joints. Several biologic treatments have been approved in Japan for psoriasis. Each biologic has a different profile for efficacy and safety, including different dosing regimens and co‐payment considerations which may complicate treatment decisions made by patients and physicians during short consultations. Elucidating patient preference is expected to contribute to shared decision‐making between patients and physicians to optimize treatment satisfaction and outcomes. However, the number of studies investigating this in Japan is very limited. The study used a discrete choice experiment methodology to elicit patient preferences for hypothetical options in an experimental framework. Participants were asked to choose their preferred treatment option from two hypothetical choices, defined by different levels of six attributes (i.e. early onset of efficacy, long‐term efficacy, sustained efficacy after drug withdrawal, dosing convenience, co‐payment and risk of serious infection). The survey included 16 treatment choice scenarios and was completed by 395 participants. Across all participants, the attribute regarded as most important was sustained efficacy after drug withdrawal, followed by dosing convenience, co‐payment, long‐term efficacy, early onset of efficacy and risk of serious infection. The study found that patients prefer treatments which have durable efficacy and lower treatment burden characterized as fewer injection frequency and lower co‐payment. These results may be helpful to understand patient preference for biologic treatments used for psoriasis in Japan and contribute to shared decision‐making between patients and physicians to improve patient satisfaction and treatment outcomes.

Int Immunopharmacol 2019; 71:301-312.

Abstract
The purpose of this study was to investigate the protective effects of ambroxol in psoriasis-like skin inflammation both in vitro and in vivo and delineate the molecular mechanism of ambroxol. Our data demonstrated that ambroxol has an imperative role in inhibiting the lipopolysaccharide (LPS) stimulated nitrite levels, total cellular and mitochondrial reactive oxygen species level which was determined by Griess assay, DCFDA, and MitoSOX Red staining, respectively. We found that ambroxol remarkably reduced imiquimod (IMQ) induced epidermal hyperplasia, psoriasis area and severity index (PASI) scoring, splenomegaly, skin, and ear fold thickness. In addition, the histopathological evaluation revealed that ambroxol topical and subcutaneous treatment eloquently reduced psoriasiform lesions including acanthosis. Moreover, with ambroxol intervention, the levels of antioxidants glutathione (GSH), superoxide dismutase (SOD), and IL-10 were found to be increased along with a reduction in nitrite levels in skin tissues. On the other hand, ambroxol treatment significantly reduced imiquimod-induced levels of inflammatory cytokines such as IL-1β, IL-6, IL-17, IL-22, IL-23, TGF-β, and TNF-α. Furthermore, from immunoblotting, we found a decrease in the protein expression of nitrotyrosine, iNOS, NF-κB and MAPKs signaling cascade with a concomitant increase in the expression of Nrf-2 and SOD-1 in RAW 264.7 cells and skin tissues by ambroxol. Similar findings were observed by immunofluorescence in macrophages. Moreover, ambroxol downregulated the ICAM-1 and Ki67 expression observed in skin tissues. Collectively, our results demonstrate that ambroxol may have intriguing therapeutic possibilities in attenuating psoriasis.

Abstract
Objective The study assessed persistence rates of biological disease-modifying antirheumatic drugs (bDMARDs) for the treatment of rheumatoid arthritis in Japan and compared resource utilization and treatment costs between persistence and non-persistence groups. Methods Data were extracted from a Japanese claims database between 2009 and 2015. bDMARD-naïve patients were identified and included in the final analysis. Survival analysis was used to estimate 1-year persistence rates for current bDMARDs. Propensity score matching was applied to control for potential treatment selection bias. Resource utilization and healthcare costs were calculated 1 year before and after initiation of bDMARDs and compared between persistence and non-persistence groups. Results A total of 6153 bDMARD-naïve patients were identified and the overall 1-year persistence rate was 85% (95% CI 84–86). Overall, 1-year outpatient visits increased from 10 at baseline to 16 after bDMARD treatment, while the number of hospital admissions declined from 3.3 to 1.6. The non-persistence group had a larger increase in outpatient visits after bDMARD initiation compared with the persistence group (8–16 vs. 10–16, respectively) and a smaller decrease in hospital admissions (3.1–1.9 vs. 3.5–1.4, respectively). Persistence was associated with a reduction in total healthcare costs of US$760. Conclusions Japanese bDMARD-naïve patients with RA have a high persistence rate with those treatments. The reduction in medication costs in non-persistent patients is offset by higher hospitalization costs, making non-persistence more expensive.
