RESUMEN
BACKGROUND: Prior work showed that patients from the CorEvitas Psoriasis Registry who had previously failed a prior biologic and then initiated ixekizumab demonstrated improvements in disease severity and patient-reported outcomes after 6 months. However, newer therapies such as interleukin-23 inhibitors (IL-23i) were not considered. Here, with more recent data including IL-23i, 6-month effectiveness of ixekizumab following a switch from any biologic was assessed as well as whether 6-month effectiveness of ixekizumab was impacted by prior biologic class. METHODS: We included CorEvitas Psoriasis Registry patients who initiated ixekizumab after discontinuing another biologic therapy and had a corresponding 6-month follow-up visit following ixekizumab initiation (N = 743, 2016-2023). Immediate prior biologic class was categorized as tumor necrosis factor inhibitor (TNFi) or interleukin-12/23 inhibitors (IL-12/23i, n = 405), non-ixekizumab interleukin-17i (IL-17i, n = 237), or IL-23i (n = 101). Adjusted mean changes in body surface area (BSA), Dermatology Life Quality Index (DLQI), itch, and skin pain were calculated for prior biologic class groups using analysis of covariance (ANCOVA). Proportions achieving ≥ 75%, ≥ 90%, and ≥ 100% improvement in Psoriasis Area and Severity Index (PASI75, PASI90, and PASI100, respectively), Investigator's Global Assessment (IGA) 0/1, and DLQI 0/1 were calculated for all patients and compared among prior biologic classes via relative risks (RRs) and 95% confidence intervals (CIs) using multivariable modified Poisson regression. RESULTS: Mean improvements in BSA, DLQI, itch, and skin pain, were 7.6, 3.6, 23.3, and 16.7, respectively, for ixekizumab patients who switched from TNFi or IL-12/23i (all p < 0.05); 6.8, 3.3, 19.6, and 14.1, respectively, for those who switched from non-ixekizumab IL-17i (all p < 0.05); and 7.8, 3.4, 22.2, and 12.8, respectively, for those who switched from IL-23i (all p < 0.05). Overall, 54%, 41%, and 31% of ixekizumab initiators achieved PASI75, PASI90, and PASI100, respectively, 50% maintained or achieved IGA 0/1, and 48% maintained or achieved DLQI 0/1. The prior TNFi or IL-12/23i group was 31% more likely to achieve PASI100 (RR = 1.31, 95% CI 1.01, 1.69) and 32% more likely to maintain or achieve IGA 0/1 (RR = 1.32, 95% CI 1.11, 1.57), but not significantly more likely to achieve PASI90. The prior IL-23i group was 45% more likely to achieve PASI90 (RR = 1.45, 95% CI 1.10, 1.91), 55% more likely to achieve PASI100 (RR = 1.55, 95% CI 1.12, 2.13), and 39% more likely to maintain or achieve IGA 0/1 (RR = 1.39, 95% CI 1.12, 1.73) compared to the prior non-ixekizumab IL-17i group. Achievement of PASI75 and DLQI 0/1 was consistent across the prior TNFi or IL-12/23i, IL-23i, and non-ixekizumab IL-17i groups. CONCLUSIONS: These updated findings with IL-23i data reaffirm that patients with psoriasis who switch to ixekizumab after discontinuing another biologic demonstrate improvement in disease severity and patient-reported outcomes at 6 months in real-world settings. Compared to patients who switched from another IL-17i, patients who switched class from a TNFi or IL-12/23i were more likely to achieve PASI100 and IGA 0/1, and patients who switched class from an IL-23i were more likely to achieve PASI90 in addition to PASI100 and IGA 0/1.
RESUMEN
INTRODUCTION: A new, citrate-free ixekizumab formulation, which is bioequivalent to the original formulation, was associated with significant reduction in injection site pain. This study evaluates patient satisfaction with the first injection experience of citrate-free ixekizumab in a real-world setting. METHODS: A non-interventional, observational, web-based survey of adults (≥ 18 years) with psoriasis, psoriatic arthritis, or axial spondyloarthritis was conducted between August 2022 and March 2023. Patients enrolled in the Taltz US Customer Support Program were identified as receiving either the original ixekizumab or initiating citrate-free ixekizumab. Patients receiving original ixekizumab completed one survey at baseline to assess satisfaction with the formulation and one survey after switching to assess satisfaction, willingness to continue using and recommending citrate-free ixekizumab, and formulation preference. Participants previously exposed to ixekizumab completed one survey to assess their satisfaction and willingness to continue using and recommending citrate-free ixekizumab. Descriptive and comparative statistics are reported for patients that switched from original to citrate-free ixekizumab (n = 361); and descriptive statistics are reported for patients not previously exposed to ixekizumab (n = 90). RESULTS: A total of 451 patients were included in the analysis. Significantly more patients were satisfied with their first injection with citrate-free ixekizumab compared to original ixekizumab (83.9% vs. 71.7% respectively; p = 0.0001). Almost all patients who switched from original ixekizumab were definitely or mostly willing to continue using and recommending citrate-free ixekizumab (93.9% and 93.4%, respectively). Additionally, 94.2% of patients who switched from original to citrate-free ixekizumab preferred citrate-free ixekizumab or had no preference. Three-fourths of patients not previously exposed to ixekizumab were satisfied with their first injection with citrate-free ixekizumab and 94.5% were definitely or mostly willing to continue using citrate-free ixekizumab. CONCLUSION: The citrate-free ixekizumab formulation was preferred and well accepted by most patients who switched from the original ixekizumab formulation. Similar findings were seen for those newly initiating citrate-free ixekizumab.

INTRODUCTION: Ixekizumab, a highly selective interleukin-17A monoclonal antibody, was approved for the treatment of moderate-to-severe psoriasis (PsO) in 2016. Limited real-world data are available on its effectiveness from a patient's perspective shortly (2 to 4 weeks) after initiation and upon continuation for 24 weeks. OBJECTIVE: To describe patient-reported clinical and quality-of-life outcomes after initiating ixekizumab using data collected from the United States Taltz® Customer Support Program. METHODS: This was a 24-week prospective, observational study of commercially insured diagnosis-confirmed adults with PsO. Surveys were completed at weeks 0 (baseline), 2, 4, 8, 12, and 24 and included the Patient Report of Extent of Psoriasis Involvement questionnaire to assess the extent of body surface area (BSA) affected by PsO, itch and pain numeric rating scales, Patient Global Assessment of Disease Severity (PatGA), and Dermatology Life Quality Index (DLQI). RESULTS: 523 patients were included in the analysis. Proportions of patients with ≤ 2% BSA involvement were 34.5%, 40.1%, 50.9%, and 79.9% at weeks 0, 2, 4, and 24, respectively; 54.8% and 75.1% achieved National Psoriasis Foundation preferred (BSA ≤ 1%) and acceptable (BSA ≤ 3% or ≥ 75% improvement) responses at week 12, respectively. Improvements of ≥ 4 points in itch and pain were seen by week 2 in 21.1% and 28.0% of patients, respectively, which increased to 63.1% and 64.8% at week 24. Proportions of patients with PatGA scores of 0 (clear) or 1 were 13.4%, 24.1%, 34.0%, and 69.6% at weeks 0, 2, 4, and 24, respectively; and proportions with DLQI total scores of 0 or 1 [no or minimal impact] were 8.4%, 17.6%, 27.3%, and 53.8% at weeks 0, 2, 4, and 24, respectively. CONCLUSION: Patient-reported improvements in BSA, itch, skin pain, dermatology-specific quality of life, and overall PsO severity were seen as early as 2 weeks after initiation and continued through week 24.
RESUMEN
BACKGROUND AND OBJECTIVE: Data on real-world healthcare costs for ixekizumab (IXE) and secukinumab (SEC) in biologic-experienced patients with psoriasis are limited. This study compared real-world costs and healthcare resource utilization between IXE and SEC in biologic-experienced patients with psoriasis over an 18-month follow-up period in the USA. METHODS: Adult patients with a diagnosis of psoriasis between 1 March, 2015 and 31 October, 2019 were identified using health insurance claims data from IBM Watson Health MarketScan®. The index date was the date of the first IXE or SEC claim. Biologic-experienced patients with one or more pre-period claims for biologic drugs were identified. Inverse probability of treatment weighting was used to reduce cohort imbalances. All-cause and psoriasis-related direct healthcare costs along with index drug costs were estimated during the follow-up and reported as per patient per month. Discount factors published by the Institute for Clinical and Economic Review were applied to psoriasis-related biologics to adjust pharmacy costs. RESULTS: A total of 411 IXE and 780 SEC users were included. After weighting, all-cause inpatient admissions were similar between IXE (9.5%) and SEC users (10.3%). Weighted, mean ± standard deviation per patient per month all-cause healthcare costs were higher in IXE users ($6670 ± $2910) than in SEC users ($6239 ± $3903; p = 0.049). Psoriasis-related and monthly index drug costs were higher in IXE users ($5609 ± $2009; p < 0.001 and $4688 ± $1994; p < 0.001, respectively) than in SEC users ($5095 ± $2291 and $3853 ± $1977, respectively). After Institute for Clinical and Economic Review adjustment, mean per patient per month all-cause ($4363 ± $2576 vs $4398 ± $3517) and psoriasis-related costs ($3302 ± $1264 vs $3253 ± $1504) were similar between the groups. Institute for Clinical and Economic Review- and adherence-adjusted mean per patient per month index drug costs were similar between IXE and SEC users (p = 0.339). CONCLUSIONS: Institute for Clinical and Economic Review-adjusted all-cause and psoriasis-related costs were comparable between IXE and SEC users among biologic-experienced patients over an 18-month follow-up period.

INTRODUCTION: Patients with psoriasis (PsO) should adhere to and be persistent with treatment to maintain disease control. Patient support programs (PSPs) are useful to support patients with disease management. We aimed to understand the real-world patient profile and persistence of ixekizumab-initiating Canadian patients with moderate-to-severe PsO using PSP data. METHODS: This retrospective observational study was conducted utilizing a Canadian PSP database (May 2016 to March 2020). Inclusion criteria were: age ≥ 18 years with moderate-to-severe PsO, initiated ixekizumab, enrolled in the PSP for ≥ 6 months, and provided informed consent. Psoriasis Area Severity Index (PASI), body surface area (BSA) involvement, and Dermatology Life Quality Index (DLQI) were collected at PSP entry. Adherence [using the proportion of days covered (PDC)] and persistence (using Kaplan-Meier curves) were assessed after 1-year and 2-year follow-ups. Differences in persistence between biologic-naïve and biologic-experienced patients were compared using Cox proportional hazards model after adjusting baseline parameters. RESULTS: In total, 1891 ixekizumab-treated moderate-to-severe patients with PsO were included. The mean [standard deviation (SD)] age was 52.3 (13.3) years; 51.1% of patients were 45-65 years old and 61.4% were male. At baseline, the mean (SD) PASI score was 14.3 (8.1), the DLQI score was 16.5 (7.7), and BSA % was 17.4 (15.1). PsO lesions were commonly located on the hands (33.4%), face (28.6%), and feet (23.8%). Ixekizumab-treated patients were highly adherent [PDC ≥ 80%: 1-year (92.0%), 2-year (87.7%)] and persistent [1-year (90.4%), 2-year (85.6%)]. Biologic-naïve patients were more adherent (1-year, 94.6% versus 87.3%; 2-year, 90.3% versus 83.5%) than biologic-experienced patients. Significantly higher persistence in biologic-naïve versus biologic-experienced patients for 1-year (p < 0.01) and 2-year (p = 0.010) follow-up periods was observed after adjusting for baseline parameters. CONCLUSION: Patients with moderate-to-severe PsO overwhelmingly remained on ixekizumab treatment for more than 2 years while participating in a PSP.
RESUMEN
INTRODUCTION: The aim of this work is to evaluate baricitinib safety with respect to venous thromboembolism (VTE), major adverse cardiovascular events (MACE), and serious infection relative to tumor necrosis factor inhibitors (TNFi) in patients with rheumatoid arthritis (RA). METHODS: Patients with RA from 14 real-world data sources (three disease registries, eight commercial and three government health insurance claims databases) in the United States (n = 9), Europe (n = 3), and Japan (n = 2) were analyzed using a new user active comparator design. Propensity score matching (1:1) controlled for potential confounding. Meta-analysis of incidence rate ratios (IRR) and incidence rate differences (IRD) for each outcome, from each data source was executed using modified Poisson regression and Cochran-Mantel-Haenszel analysis. RESULTS: Of 9013 eligible baricitinib-treated patients, 7606 were propensity score-matched with TNFi-treated patients, contributing 5879 and 6512 person-years of baricitinib and TNFi exposure, respectively. Across data sources, 97 patients (56 baricitinib) experienced VTE during follow-up, 93 experienced MACE (54 baricitinib), and 321 experienced serious infection (176 baricitinib). Overall IRRs comparing baricitinib with TNFi treatment were 1.51 (95% CI 1.10, 2.08) for VTE, 1.54 (95% CI 0.93, 2.54) for MACE, and 1.36 (95% CI 0.86, 2.13) for serious infection. IRDs for VTE, MACE, and serious infection, respectively, were 0.26 (95% CI -0.04, 0.57), 0.22 (95% CI -0.07, 0.52), and 0.57 (95% CI -0.07, 1.21) per 100 person-years greater for baricitinib than TNFi. CONCLUSIONS: Overall results suggest increased risk of VTE with baricitinib versus TNFi, with consistent point estimates from the two largest data sources. A numerically greater risk was observed for MACE and serious infection when comparing baricitinib versus TNFi, with different point estimates from the two largest data sources. Findings from this study and their impact on clinical practice should be considered in context of limitations and other evidence regarding the safety and efficacy of baricitinib and other Janus kinase inhibitors.

RESUMEN
INTRODUCTION: The aim of this work is to describe real-world biologic-experienced psoriasis patients initiating ixekizumab by prior biologic therapy status and compare the effectiveness of ixekizumab between patients who previously failed secukinumab and those who failed other biologics. We hypothesized that (1) clinical outcomes and patient-reported outcomes would improve following a switch to IXE, and (2) there would be no differences in responses between patients who previously failed secukinumab and those who failed other biologics. METHODS: Participants (n = 419) included adult psoriasis patients enrolled in the CorEvitas Psoriasis Registry through 9/10/20 who switched to ixekizumab after discontinuing another biologic. Patients were classified by the biologic used immediately prior to ixekizumab and reason for discontinuation: prior secukinumab failure; prior secukinumab non-failure; prior other biologic failure; and prior other biologic non-failure. Discontinuations for efficacy reasons were considered failures; all others were considered non-failures. Baseline descriptive statistics were calculated. Multivariable Poisson regression models estimated the likelihood of response of other failure relative to secukinumab failure. RESULTS: Mean age was 51 years; 48% were women. Psoriasis disease characteristics were similar across prior biologic groups. At 6-month follow-up, disease severity improved for all who initiated ixekizumab after discontinuing another biologic. Secukinumab failure patients who switched to ixekizumab achieved BSA ≤ 1 (49%), BSA ≤ 3 (59%), PASI75 (46%), PASI ≤ 3 (64%), and IGA ≤ 1 (40%). Other failure patients achieved BSA ≤ 1 (55%), BSA ≤ 3 (72%), PASI75 (59%), PASI ≤ 3 (74%), and IGA ≤ 1 (54%). In regression modeling, we observed patients in the other biologics failure group had an increased likelihood of achieving response for BSA ≤ 3, PASI75, PASI90, PASI100, and IGA ≤ 1 compared to patients who failed secukinumab. CONCLUSIONS: These findings suggest that patients with psoriasis who switch to ixekizumab after discontinuing another biologic demonstrate improvement in disease severity after six months. Patients who discontinued biologics other than secukinumab may be more likely to respond to ixekiziumab compared to those who switched from secukinumab.
RESUMEN
OBJECTIVE: The aim of this study was to compare healthcare costs between ixekizumab (IXE)-treated and secukinumab (SEC)-treated patients with psoriasis over a 24-month follow-up period in the United States. METHODS: Patients with psoriasis diagnosis were identified from IBM Watson Health MarketScan® Research Databases; those with one or more claim for index drug (IXE or SEC) between March 1, 2016 and October 31, 2019 were included. Included patients were ≥ 18 years old and had continuous enrollment with medical and pharmacy benefits ≥ 6 months before and ≥ 24 months after index date. Patients were classified as IXE or SEC users based on drug received at index. Per patient per month (PPPM) all-cause, psoriasis-related, and index drug costs for IXE and SEC users were estimated over 24 months of follow-up. Institute for Clinical and Economic Review (ICER) discount factors were applied to adjust pharmacy costs. Index drug costs were additionally adjusted for adherence. Inverse probability of treatment weighting was used to address cohort imbalances. Chi-square/t tests were used to compare IXE versus SEC users; p value < 0.05 was considered statistically significant. RESULTS: Overall, 1461 patients (IXE users, n = 471; SEC users, n = 990) were included. IXE versus SEC users had higher weighted PPPM all-cause, psoriasis-related, and index drug costs (p ≤ 0.001). IXE versus SEC users had comparable ICER-adjusted mean PPPM all-cause costs (US$4172 ± 3349 vs US$3978 ± 2619; p = 0.227) and psoriasis-related costs (US$2950 ± 1332 vs US$2899 ± 1152; p = 0.447). After applying ICER and adherence adjustments, index drug costs were similar between IXE and SEC users (US$3794 ± 1822 vs US$3766 ± 1973; p = 0.795). CONCLUSIONS: All-cause and psoriasis-related costs were comparable between IXE and SEC users after ICER adjustments; index drug costs were similar after ICER and adherence adjustments.
RESUMEN
INTRODUCTION: Limited real-world data are available comparing multiple biologics on their adherence, persistence, and the use of concomitant biologics in the treatment of moderate-to-severe psoriasis in clinical practice. The objective was to compare persistence of and adherence to ixekizumab (IXE) treatment, as monotherapy or with concomitant medication, versus patients receiving other commonly prescribed biologics. METHODS: Patients who newly initiated IXE, adalimumab (ADA), etanercept (ETN), secukinumab (SEC), or ustekinumab (UST) in IBM MarketScan® databases with diagnosis of psoriasis were identified. Treatment comparisons on medication persistence, adherence, and monotherapy were based on balanced samples after inverse probability of treatment weighting (IPTW). RESULTS: A higher proportion of patients receiving IXE had had previous biologic therapies (50.3%) versus other biologics (ADA: 9.1%, ETN: 10.9%, SEC: 33.9%, UST: 19.7%). Patients treated with IXE showed statistically (p < 0.001) greater persistence than patients treated with SEC, ADA, UST, or ETN at both 1-year follow-up and up to 3 years of follow-up. Adherence for patients treated with IXE was significantly (p < 0.001) higher compared to ADA, ETN, and UST at both 1-year follow-up and up to 3 years of follow-up. There was no significantly higher adherence in patients treated with IXE compared to those treated with SEC at 1-year follow-up, but IXE had higher adherence than SEC (p < 0.05) at 1-3 year follow-up. IXE showed longer time on monotherapy than ADA (p < 0.001), ETN (p < 0.001), SEC (p < 0.05), and UST (p < 0.001) for both 1-year and 1-3 year follow-up. Sensitivity analyses on persistence, adherence, and monotherapy with further model adjustments after IPTW confirmed the findings. CONCLUSIONS: Patients treated with IXE were more persistent on and adherent to treatment and remained on monotherapy longer compared to those on all other commonly prescribed biologics combined or with individual biologics.

AIMS: To compare long-term healthcare resource utilization (HCRU) and costs among patients who initiated ixekizumab (IXE) or adalimumab (ADA) for treatment of psoriasis in the United States. METHODS: Adult patients with psoriasis who had ≥1 claim for IXE or ADA were identified from IBM MarketScan claims databases prior to the COVID-19 pandemic (1 March 2016-31 October 2019). The index date was the date of first claim for the index drug of interest. Inverse probability of treatment weighting was employed to balance treatment cohorts. All-cause and psoriasis-related HCRU and costs were examined for 24 months of follow-up. Costs were reported as per patient per month. Costs of psoriasis-related biologics were adjusted using published Institute for Clinical and Economic Review (ICER) discount factors. Index drug costs were adjusted for adherence and ICER discount rates. RESULTS: The analyses included 407 IXE and 2,702 ADA users. IXE users had significantly higher inpatient admission rate (all-cause HCRU: 14.9% vs. 11.0%; p =0.012) and greater mean length of stay per admission (days, 6.6 vs. 4.1; p =0.004) than ADA users. ICER-adjusted costs were significantly higher in IXE than ADA users (all-cause costs: $4,132 vs. $3,610; p <0.001; psoriasis-related costs $3,077 vs. $2,700; p <0.001). After adjusting for ICER and adherence, IXE and ADA drug costs were comparable ($3,636 vs. $3,677; p =0.714). LIMITATIONS: Study relied on administrative claims data, subjected to data coding limitations and data entry errors. Rebates, patient assistance programs, and commission to wholesalers are not always captured in claims. Adjustment made by ICER discount factors may lead to double-discounting if the discounts have been applied in claim payments. CONCLUSIONS: All-cause HCRU was higher in IXE than ADA users. Healthcare costs were also higher in IXE than ADA users after ICER adjustment, over 24 months. Cost differences were largely driven by higher treatment adherence associated with IXE. Index drug costs were comparable after ICER and adherence adjustments.

BACKGROUND: There is a paucity of long-term real-world evidence comparing the effectiveness of ixekizumab (IXE) and adalimumab (ADA). We compared real-world treatment patterns of IXE-treated and ADA-treated patients with psoriasis over 24 months in the United States. METHODS: A retrospective observational study was conducted using IBM Watson Health MarketScan® databases. Adult patients with psoriasis having ≥1 claim for IXE or ADA from March 1, 2016 – October 31, 2019 were identified. Inverse probability of treatment weighting (IPTW) was used to address cohort imbalances. Cox proportional hazards models were used to estimate the risks of non-persistence, discontinuation, and switching. Logistic regression was used to estimate odds of high adherence. Persistence, adherence, discontinuation, reinitiation, and dosing and switching rates were also analyzed. RESULTS: The final cohorts comprised 475 IXE users and 3159 ADA users over 24 months. IXE users demonstrated higher adherence (36.3% vs 28.8%; P<0.001) and persistence rates (35.2% vs 28.8%; P=0.004), and a lower discontinuation rate (59.1% vs 65.3%; P=0.007) compared to ADA users. IXE users had a higher likelihood of being treatment-adherent compared to ADA users (OR=1.52, 95% CI: 1.24–1.87), a lower risk of non-persistence (HR=0.84, 95% CI: 0.75–0.95), and a lower risk of discontinuation (HR=0.83, 95% CI: 0.74–0.94), respectively. Switching rates were similar in both groups (31.2% vs 30.0%; P=0.608). CONCLUSION: IXE users had better treatment adherence and persistence, and a lower risk of discontinuation compared to ADA users over 24 months. There was no difference in the risk of switching between IXE and ADA. J Drugs Dermatol. 2022;21(4):399-407. doi:10.36849/JDD.6336.

INTRODUCTION: This cross-sectional survey was conducted with National Psoriasis Foundation (NPF) to capture treatment perspectives and expectations in patients with psoriasis (PsO) using Patient Needs Questionnaire (PNQ) of Patient Benefit Index (PBI). METHODS: Adult participants with self-reported diagnosis of PsO responded to the PNQ portion of PBI by indicating how much they valued different treatment attributes. All the treatment goals were captured on a five-point Likert scale (0 = "Not important", 4 = "Very important"). Treatment goals were obtained for overall population and subgroups based on severity of disease Patient Global Assessment (PGA), age, gender, and Dermatology Life Quality Index (DLQI) total score. All data were expressed as mean and standard deviation [SD]. RESULTS: A total of 1200 participants completed the survey (mean age 51.5 years). Top treatment goal in the overall population was "to have confidence in the therapy" (3.46 [1.01]). Unique to the higher severity subgroup (PGA ≥ 3), "to find a clear diagnosis and therapy" was a top five goal and "to get better skin quickly" was for those with lesser severity (PGA < 3). "To be free of itching" (3.36 [0.99]) was the unique goal in the < 40 age group whereas it was "to get better skin quickly" (3.27 [1.12]) in the ≥ 40 group. In women and men, "to be free of itching" (3.38 [1.13]) and "to get better skin quickly" (3.20 [1.09]) were top five goals, respectively. Patients with ≥ 10 DLQI scores expressed higher treatment goal "to regain control of the disease" (3.66 [0.67]) compared to those with ≤ 10 DLQI scores who expressed "to have confidence in the therapy" (3.40 [1.11]) as the topmost treatment goal. CONCLUSION: Our results suggest that in patients with PsO, treatment preferences can vary with different characteristics such as age, severity, and gender as measured by using PNQ. Further exploration of this data will help inform treatment decisions and optimize patient outcomes.

Although alopecia areata (AA) severity is often defined by the degree of scalp hair loss, its impact on QOL can also be a defining measure of severity. In this cross-sectional study (AA Disease Specific Program), 259 patients were surveyed for demographics, AA illness characteristics, QOL (Skindex-16 AA), and daily impairment (Work Productivity and Activity Impairment). The association between patient demographics and illness variables, the Skindex-16 AA scores, and the Work Productivity and Activity Impairment scores were analyzed using regression analyses. The mean age of patients was 39 years (51% female). Self-reported severity of current AA was rated as mild (21%), moderate (54%), and severe (25%). The highest impairment was observed for the Skindex-16 AA emotions and the Work Productivity and Activity Impairment daily activity performance scores. Although the degree of scalp hair loss (physician Severity of Alopecia Tool score) was not predictive of QOL, patients' self-report of moderate or severe disease, sex (females more impacted), and eyebrow and eyelash involvement were predictors of diminished QOL, consistently and incrementally. The present results suggest patients' perception of severity as well as the presence of eyelash and eyebrow hair loss are also impactful and should be considered in defining the severity of disease.

INTRODUCTION: Persistence and adherence to psoriasis treatments reflect overall drug effectiveness, tolerability, and convenience. Limited data are available on the treatment patterns of ixekizumab, an interleukin (IL)-17A antagonist, vs. guselkumab, an IL-23 inhibitor. Our objective was to evaluate real-life psoriasis drug treatment patterns with ixekizumab vs. guselkumab. METHODS: This retrospective observational study used United States insurance claims data from IBM Watson MarketScan Databases to analyze treatment patterns (including adherence, persistence, time on monotherapy, switching, and use of concomitant medications) for patients with 1 year, ≥ 6 months, and up to 30 months of follow-up. Outcomes were compared between ixekizumab and guselkumab on the balanced sample after applying inverse probability of treatment weighting (IPTW). RESULTS: Data for 1414 eligible patients (ixekizumab, N = 674 and guselkumab, N = 740) were assessed. Over the 1-year follow-up, adherence was greater for ixekizumab vs. guselkumab when evaluated by proportion of days covered ≥ 80% [odds ratio (OR) 1.77 (95% confidence interval, 1.41, 2.21), p < 0.001] and by medication possession ratio ≥ 80% [OR = 1.92 (1.54, 2.38), p < 0.001]. Persistence was longer for ixekizumab vs. guselkumab with a 60-day allowable gap [non-persistence hazard ratio (HR) (95% confidence interval): 0.80 (0.69, 0.93), p = 0.005], but there were no differences with a 90-day allowable gap [HR = 0.98 (0.83, 1.17), p = 0.850]. Results assessed in patients with ≥ 6 months follow-up confirmed these findings. This retrospective analysis of a United States claims database used prescription refill data to estimate persistence/adherence. CONCLUSIONS: Based on real-world evidence using claims data, patients with psoriasis treated with ixekizumab had a greater adherence to and an equal or greater persistence with therapy vs. patients treated with guselkumab.
In real-world settings, how consistently patients take a drug (adherence) and how long they continue taking it (persistence) are thought to reflect patients' satisfaction with the combination of efficacy and tolerability of the treatment. In this study of patients with psoriasis, we compared these measuresregularity of prescription refills and continued time on drugbetween patients receiving ixekizumab or guselkumab for their psoriasis. This information was taken from a large insurance claims database, and so reflects results among commercially insured patients in the United States. We found that patients taking ixekizumab more consistently obtained prescription refills during the study period. Patients taking ixekizumab or guselkumab continued treatment for similar lengths of time when we allowed a longer gap of 90 days between prescription refills, but when a shorter gap of 60 days was allowed, those on ixekizumab spent a longer time on treatment. The findings were consistent regardless of prior treatment with other similar drugs (biologics). Overall, these findings indicate that for ixekizumab, which is dosed once every 4 weeks, and guselkumab, which is dosed once every 8 weeks, patients took ixekizumab more regularly and continued on the drug for about the same or a longer amount of time compared to patients taking guselkumab. These results may help dermatology practitioners in selecting biologic drugs for their patients with psoriasis.
RESUMEN
INTRODUCTION: Both early clinical improvement and long-term maintenance of clinical efficacy of treatments matter to patients with psoriasis. We compared cumulative clinical benefits of treatment with biologics over 1 year based on the area under the curve (AUC) for Psoriasis Area and Severity Index (PASI) 100 and PASI 90 responses in patients with moderate-to-severe psoriasis using a network meta-analysis (NMA). METHODS: Published phase 3 randomized, placebo- or active-controlled clinical trial data for biologics approved for the treatment of moderate-to-severe psoriasis were obtained from a systematic literature review up to 30 September 2020. Eighteen clinical trials that included data from baseline to 48 or 52 weeks where AUC could be calculated were included. Data were compared using a fixed-effect model with a separate random-effect baseline model to account for effects of the placebo arm. Cumulative clinical benefit was estimated using the AUC for PASI 100 and PASI 90 responses (complete and almost-complete skin clearance, respectively). Normalized AUC was compared using Bayesian NMA. Cumulative days of response were calculated using normalized AUC and study duration. RESULTS: Interleukin (IL)-17 and IL-23 inhibitors demonstrated greater cumulative clinical benefits for both PASI 100 and PASI 90 versus IL-12/23 and tumor necrosis factor inhibitors. Over 52 weeks, cumulative days with PASI 100 were greatest with ixekizumab [158.7 (95% credible interval, 147.4, 170.0) days] followed by risankizumab [154.0 (144.9, 163.4) days]; PASI 90 days were greatest with risankizumab [249.3 (239.5, 259.2) days] followed by ixekizumab [238.8 (227.1, 250.8) days]. Both ixekizumab and risankizumab showed greater cumulative days with PASI 100 or PASI 90 responses versus secukinumab [117.9 (110.7, 125.2) and 215.5 (208.2, 223.1) days, respectively] and greater cumulative days with PASI 100 versus guselkumab [130.7 (120.5, 140.9) days]. CONCLUSION: For complete and almost-complete skin clearance, ixekizumab and risankizumab provided the greatest cumulative clinical benefits over 1 year.
RESUMEN
BACKGROUND: Biologic and targeted synthetic disease-modifying antirheumatic drug (tsDMARD) therapies are used in management of psoriatic arthritis (PsA). Although previous studies have demonstrated that rates of adherence, persistence, discontinuation, and switching, as well as health care costs, are variable among treatments, limited published data exist on more recently approved therapies. OBJECTIVE: To describe adherence, persistence, discontinuation, reinitiation, switching, dosing patterns, and health care costs among PsA patients treated with biologics and tsDMARDs. METHODS: This was a real-world, retrospective administrative claims study. Adult PsA patients with at least 1 claim for an approved PsA biologic (adalimumab, certolizumab, etanercept, golimumab, infliximab, secukinumab, or ustekinumab) or tsDMARD (apremilast or tofacitinib) between January 1, 2015, and June 30, 2019, were selected from the IBM MarketScan administrative claims databases. The first claim for one of the study treatments determined the index date and drug cohort. Patients were required to be continuously enrolled in their health plans for 12 months before and after the index date and to have at least 1 claim with a diagnosis of PsA in the 12 months before or on the index date. Adherence (measured by proportion of days covered [PDC] and medication possession ratio [MPR]), persistence (< 60-day gap in treatment), discontinuation (> 90-day gap), reinitiation of index drug, switching, and dosing patterns for each index drug were assessed during the 12-month follow-up period. Health care costs were reported per patient per month (PPPM) during the 12-month follow-up and assessed after adjusting PsA treatment costs by the Institute for Clinical and Economic Review discount factors to account for discounts and rebates not usually reflected in claims data and by adherence. RESULTS: Overall, 6,674 patients met the selection criteria. The top 3 index drugs were adalimumab (37%), apremilast (26%), and etanercept (18%). Over 12 months of follow-up, 31%-59% of patients remained persistent on the index drug, whereas 35%-56% discontinued, 13%-29% switched to a different biologic or tsDMARD, and 3%-15% reinitiated the index therapy, depending on the index drug. The mean PDC ranged from 0.51 to 0.69 during the 12-month follow-up and 0.80 to 0.93 during the follow-up period before discontinuation. Dose values were largely consistent with prescribing information, with the exception of secukinumab. Index drug costs PPPM ranged from $2,361 (apremilast) to $6,528 for ustekinumab after adjustment for discounts and adherence. CONCLUSIONS: Results from this real-world analysis suggest that there is substantial variability in persistence, discontinuation, adherence, reinitiating, and switching patterns among the different biologic and tsDMARD treatment options for PsA patients. In addition, this study provides real-world cost data for biologics and tsDMARDs among patients with PsA.

OBJECTIVE: To assess treatment patterns of Ixekizumab (IXE) and evaluate the speed of onset and long-term clinical and quality-of-life outcomes among a subset of patients who switched from adalimumab (ADA) and secukinumab (SEC) to IXE in a real-world setting. METHOD: A retrospective chart review study was conducted at a single US dermatology referral center. RESULT: 153 patients were included in the study, 69.3% of patients were biologic-experienced. ADA was the most commonly used biologic prior to IXE initiation. 66.7% of patients remained on IXE at the study end. 47.7% of patients received concomitant methotrexate, and usage decreased consistently after 1 month. IXE treatment duration was longer among patients who were early responders (achieved sPGA (0,1) at 1 month) vs. non-early responders. 69.4% and 43.3% of patients who switched from ADA and SEC to IXE achieved sPGA (0,1) by week 4, respectively. CONCLUSION: Patients who switched to IXE, specifically from ADA or SEC, had rapid treatment response as well as desirable long-term outcomes. IXE persistence was longer among early responders than non-early responders. Concomitant usage of methotrexate prior to switching to IXE and as a concomitant bridging treatment was reduced after IXE initiation while the proportion of patients achieving treatment targets remained high.

BACKGROUND: Real-world data on long-term treatment patterns associated with interleukin-17A inhibitors in plaque psoriasis are lacking. OBJECTIVE: To compare ixekizumab or secukinumab treatment patterns over a 24-month period among plaque psoriasis patients. METHODS: Adult patients with psoriasis who had 1 or more claims for ixekizumab or secukinumab between March 1, 2016, and October 31, 2019, and with 24 months of follow-up after starting treatment were identified from IBM MarketScan claims databases. Inverse probability of treatment weighting and multivariable models were employed to balance cohorts and estimate the risks of nonpersistence, discontinuation, and switching and odds of highly adherent treatment (proportion of days covered ≥ 80%). RESULTS: A total of 471 ixekizumab and 990 secukinumab users were included. Compared to secukinumab, ixekizumab use was associated with a 20% lower risk of nonpersistence (hazard ratio, 0.80; 95% CI, 0.70-0.92), a 17% lower risk of discontinuation (hazard ratio, 0.83; 95% CI, 0.72-0.96), and a 42% higher odds of being highly adherent to treatment (odds ratio, 1.42; 95% CI, 1.12-1.80). No difference in risk of switching was observed (hazard ratio, 0.83; 95% CI, 0.68-1.01). LIMITATIONS: Disease severity and clinical outcomes were unavailable. CONCLUSION: Over 24 months, ixekizumab users exhibited better persistence and adherence, and a lower risk of discontinuation than secukinumab users in real-world settings.

OBJECTIVE: To evaluate the effect of ixekizumab on self-reported functioning and health in patients with active nonradiographic axial spondyloarthritis (SpA). METHODS: COAST-X was a randomized, controlled trial conducted in patients with nonradiographic axial SpA over 52 weeks. Participants were randomized at a ratio of 1:1:1 to receive 80 mg of ixekizumab subcutaneously every 4 weeks or 2 weeks or placebo for 52 weeks. Self-reported functioning and health end points included the Medical Outcomes Study Short Form 36 (SF-36) health survey, Assessment of Spondyloarthritis International Society (ASAS) health index, and European Quality of Life-5 Dimensions-5 Level (EQ-5D-5L) health-utility descriptive system. RESULTS: Compared to placebo, ixekizumab treatment resulted in improvement of SF-36 physical component summary scores from baseline, with a score of 4.7 improving to 8.9 with ixekizumab therapy every 4 weeks (P < 0.05) and a score of 9.3 with ixekizumab therapy every 2 weeks (P < 0.01); the greatest improvements were observed in the domains of physical functioning, role-physical, and bodily pain at weeks 16 and 52. A higher proportion of patients receiving ixekizumab therapy every 2 weeks reported ≥3 improvements based on the ASAS health index from baseline to weeks 16 and 52 (P < 0.05). Significantly more patients receiving ixekizumab every 4 weeks reported improvements in "good health status" on the ASAS health index (ASAS score of ≤5) at weeks 16 and 52 (P < 0.05). Patients receiving ixekizumab reported improvements on the EQ-5D-5L compared to those who received placebo at week 16 (0.11 versus 0.17 for patients receiving treatment every 4 weeks and 0.19 for patients receiving treatment every 2 weeks; P < 0.05), which remained consistent at week 52. There were no clinical meaningful differences in responses based on the ixekizumab dosing regimen for patients who received ixekizumab therapy every 2 weeks or every 4 weeks. CONCLUSION: In patients with nonradiographic axial SpA, therapy with ixekizumab was superior to placebo in the improvement of self-reported functioning and health at weeks 16 and 52.
