Impact of disease, musculoskeletal symptoms and disease control in the CorEvitas Psoriasis Registry.

BACKGROUND: Early identification, diagnosis and symptom control of psoriatic arthritis (PsA) in patients with psoriasis remain unmet medical needs. OBJECTIVES: To compare the impact of disease and other characteristics between patients with psoriasis who screened positive for PsA using the Psoriasis Epidemiology Screening Tool (PEST) (screen-positive group) and patients who (i) have PsA (PsA group) or (ii) screened negative for PsA (screen-negative group). Also, to determine the proportion of patients at a patient-acceptable symptom state (PASS) in the screen-positive and PsA groups. METHODS: This was a cross-sectional analysis of the CorEvitas Psoriasis Registry. We included a convenience sample of patients with psoriasis from the screen-positive and PsA groups who completed the Psoriatic Arthritis Impact of Disease-12 (PsAID12), and a comparator screen-negative group who did not complete the PsAID12. We report descriptive summaries of demographics, comorbidities, psoriasis characteristics, patient-reported outcome measures and the proportion of patients at PASS (i.e. PsAID12 ≤ 4). RESULTS: The screen-positive, PsA and screen-negative groups included 369, 70 and 4724 patients, respectively. The screen-positive and PsA groups had a similar impact of disease, demographics, comorbidities and psoriasis characteristics (d < 0.337). Mean PsAID12 scores were 3.1 (SD 2.3) and 3.7 (SD 2.6) in the screen-positive and PsA groups, respectively. Compared with patients who screened negative for PsA, patients who screened positive exhibited higher rates of selected known predictors of PsA such as older age, longer psoriasis duration, nail disease and inverse psoriasis. The proportion of patients at PASS was 56% and 67% for the PsA and screen-positive groups, respectively. CONCLUSIONS: The similar profiles between screen-positive and PsA groups, in comparison with the screen-negative group, support observations of possible underdiagnosis of PsA and the increased impact of disease, especially musculoskeletal disease, among patients who screen positive for PsA. The high percentage of patients not at an acceptable symptom state in the PsA and screen-positive groups highlights the need to optimize care in PsA.

Patterns in the Sequential Treatment of Patients With Rheumatoid Arthritis Starting a Biologic or Targeted Synthetic Disease-Modifying Antirheumatic Drug: 10-Year Experience From a US-Based Registry.

OBJECTIVE: Developing and evaluating new treatment guidelines for rheumatoid arthritis (RA) based on observational data requires a quantitative understanding of patterns in current treatment practice with biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). METHODS: We used data from the CorEvitas RA registry to study patients starting their first b/tsDMARD therapy, defined as the first line of therapy, between 2012 and the end of 2021. We identified treatment patterns as unique sequences of therapy changes following and including the first-line therapy. Therapy cycling was defined as switching back to a treatment from a previously used therapeutic class. RESULTS: A total of 6015 b/tsDMARD-naïve patients (77% female) were included in the analysis. Their median age was 58 years, and their median disease duration was 3 years. In 2012-2014, 80% of the patients started a tumor necrosis factor inhibitor (TNFi) as their first b/tsDMARD. However, the use of TNFi decreased in favor of Janus kinase inhibitors since 2015. Although the number of treatment patterns was large, therapy cycling was relatively common. For example, 601 patterns were observed among 1133 patients who changed therapy at least four times, of whom 85.3% experienced therapy cycling. Furthermore, the duration of each of the first three lines of therapy decreased over the past decade. For example, the median duration of the first-line therapy was 153 days in 2018-2021 compared to 208 days in 2015-2017 (P < 0.001). CONCLUSION: First-line therapy was almost always TNFi, but diversity in treatment choice was high after that. This practice variation allows for proposing and evaluating new guidelines for sequential treatment of RA. It also presents statistical challenges to compare patients with different treatment sequences.

Characteristics of Patients with Crohn's Disease With or Without Perianal Fistulae in the CorEvitas Inflammatory Bowel Disease Registry.

BACKGROUND: There are limited real-world data characterizing perianal fistulae in patients with Crohn's disease (CD). AIM: To describe characteristics of patients with CD with and without perianal fistulae. METHODS: In this cross-sectional study, characteristics, treatment history, and health outcomes of patients with CD enrolled in the CorEvitas IBD Registry were described according to perianal fistula status (current/previous or none). RESULTS: Eight hundred and seventy-eight patients were included. Compared with patients with no perianal fistulae (n = 723), patients with current/previous perianal fistulae (n = 155) had longer disease duration since CD diagnosis (mean 16.5 vs 12.3 years; difference 4.3 years; 95% CI, 2.0, 6.6) and fewer had Harvey-Bradshaw Index scores indicative of remission (0-4, 56.8% vs 69.6%; difference - 12.9%; 95% CI, - 21.6, - 4.2). More patients with current/previous fistulae reported a history of IBD-related emergency room visits (67.7% vs 56.1%; difference 11.6%; 95% CI, 3.4, 19.8), hospitalizations (76.1% vs 58.4%; difference 17.7%; 95% CI, 10.1, 25.4), and surgeries (59.4% vs 27.7%; difference 31.7%; 95% CI, 23.3, 40.1), and a history of treatment with tumor necrosis factor inhibitors (81.3% vs 60.7%; difference 20.6%; 95% CI, 13.5, 27.7), immunosuppressants (51.6% vs 31.2%; difference 20.4%; 95% CI, 11.9, 29.0), and antibiotics (50.3% vs 23.7%; difference 26.6%; 95% CI, 18.2, 35.1) than patients without perianal fistulae. CONCLUSIONS: Patients with CD with current/previous perianal fistulae have more symptomatic experiences of disease, higher medication use, hospitalization rates, and emergency room visits than patients without perianal fistulae. Interventions to prevent/reduce risk of developing fistulae may help improve outcomes in CD.

Outcomes in Ixekizumab Patients Following Exposure to Secukinumab and Other Biologics in the CorEvitas Psoriasis Registry.

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.

Disease response and patient-reported outcomes among initiators of ixekizumab.

OBJECTIVES: There is limited real-world evidence on using ixekizumab in psoriasis patients. Therefore, we characterized patients with psoriasis initiating ixekizumab and report 6-month changes in disease and patient-reported outcomes. METHODS: Adult patients with psoriasis who initiated ixekizumab and completed a 6-month follow-up visit were enrolled from the Corrona Psoriasis Registry. Disease characteristics and outcomes were assessed at ixekizumab initiation. Outcomes included the mean 6-month change in Psoriasis Area and Severity Index (PASI), body surface area (BSA), Investigator Global Assessment (IGA), and IGA*BSA. RESULTS: From baseline to follow-up in all patients (n = 136), means decreased for IGA*BSA (-45.5) and BSA (-12.4), and a higher % achieved an absolute PASI ≤ 5 (84.6%), BSA 0-3 (72.1%), and IGA 0/1 (50.7%). Within stratified groups, means decreased for PASI <12 for IGA*BSA (-21.1) and BSA (-6.3); PASI≥12 for IGA*BSA (-94.8) and BSA (-24.6); weight <100 kg for IGA*BSA (-45.1) and BSA (-12.4); weight ≥100 kg for IGA*BSA (-46.2) and BSA (-12.3); concomitant PsA for IGA*BSA (-56.0) and BSA (-15.3); and in no concomitant PsA for IGA*BSA (-36.9) and BSA (-10.0). CONCLUSIONS: We provide real-world evidence on the benefits of ixekizumab for treating psoriasis, regardless of baseline disease severity, weight, or concomitant PsA.

Disease Burden and Patient-Reported Outcomes Among Ulcerative Colitis Patients According to Therapy at Enrollment Into CorEvitas' Inflammatory Bowel Disease Registry.

Background: To evaluate disease burden and patient-reported outcomes (PROs) of ulcerative colitis (UC) patients at enrollment into CorEvitas' Inflammatory Bowel Disease Registry by therapy class. Methods: Between May 3, 2017 and September 3, 2019, 773 UC registry patients were categorized by therapy class at enrollment: patients on 5-aminosalicylic acids (5-ASAs) only (n = 290), and patients on biologics/Janus kinase inhibitors (JAKi) alone or in combination with 5-ASAs or immunosuppressant therapies (BIO/JAKi) (n = 315). To quantify between group differences, the mean/proportional differences and corresponding 95% CIs were calculated. Results: Among 605 UC patients at enrollment, BIO/JAKi patients were younger (44.1 vs. 50.9 years) more were female (58.0% vs. 49.7%), had lower remission (45.4% vs. 60.0%), had more moderate/severe disease (16.5% vs. 7.1%), experienced less proctitis (10.5% vs. 22.1%), but more pancolitis (54.6% vs. 34.1%), more corticosteroid experience (70.8% vs. 44.5%), previous biologic experience (1 prior: 21.6% vs. 2.4%; 2+ prior: 12.1% vs. 0.3%), and shorter duration of current UC therapy (1.6 vs. 3.5 years) than 5-ASAs patients. BIO/JAKi patients had higher current employment than 5-ASAs patients (70.7% vs. 62.4%) and higher mean Work Productivity and Activity Impairment (WPAI) domains for absenteeism (7.3 vs. 2.8) and activity impairment (22.0 vs. 17.5). Conclusions: Among UC patients in a real-world setting, BIO/JAKi patients had less remission, more moderate-to-severe disease, and worse PROs than 5-ASAs patients. These results suggest that despite increased therapeutic options, patients with UC currently being treated with biologics or JAKi may still experience disease burden and continued unmet needs.

Characterization of Patients with Psoriasis in Challenging-to-Treat Body Areas in the Corrona Psoriasis Registry.

BACKGROUND: Real-world studies evaluating patients with challenging-to-treat localizations of psoriasis (scalp, nail, and palmoplantar) are limited. OBJECTIVE: To characterize patients with versus without psoriasis in challenging-to-treat areas seen in routine US clinical practice. METHODS: This retrospective observational study included all adult patients with psoriasis enrolled in the Corrona Psoriasis Registry between April 2015 and May 2018 who initiated a biologic therapy at registry enrollment. Patients were stratified by the presence of scalp, nail, or palmoplantar psoriasis (nonmutually exclusive groups). Patient demographics, clinical char-acteristics, disease activity, and patient-reported outcome measures (pain, fatigue, itch, EuroQol visual analog scale [EQ VAS], Dermatology Life Quality Index [DLQI], and Work Productivity and Activity Impairment questionnaire [WPAI]) were assessed at registry enrollment and compared between patients with versus without each challenging-to-treat area using nonparametric Kruskal-Wallis tests for continuous variables and χ2 or Fisher exact tests for categorical variables. Generalized linear regression models were used to estimate differences in disease activity and patient-reported outcomes between patients with versus without each challenging-to-treat area. RESULTS: Among 2,042 patients with psoriasis (mean age [±SD], 49.6 ± 14.7 years; 51.5% male), 38.4% had psoriatic arthritis (PsA), 38.1% had scalp psoriasis, 16.0% had nail psoriasis, 10.9% had palmoplantar psoriasis, and 26.2% had a combination of ≥2 challenging-to-treat areas and PsA; only 34.2% had body plaque psoriasis without PsA or challenging-to-treat areas. Patients in all challenging-to-treat groups reported higher (mean [95% CI]) itch (scalp, 58.01 [57.62-58.40] vs. 54.35 [53.99-54.72]; nail, 56.42 [56.02-56.81] vs. 55.59 [55.20-55.97]; palmoplantar, 60.22 [59.86-60.59] vs. 55.15 [54.79-55.54]) and lower EQ VAS (scalp, 68.12 [67.78-68.48] vs. 69.46 [69.12-69.81]; nail, 66.21 [65.89-66.55] vs. 69.48 [69.14-69.83]; palmoplantar, 66.21 [66.07-66.75] vs. 69.29 [68.94-69.94]) scores than those without the respective challenging-to-treat localization. Patients with nail or palmoplantar psoriasis reported higher pain, fatigue, and DLQI scores than those without. Higher proportions of patients with scalp or palmoplantar psoriasis reported work impairment compared with those without. CONCLUSION: Two-thirds of patients with psoriasis who initiated biologic therapy had PsA and/or ≥1 challenging-to-treat area. Patients with challenging-to-treat areas had worse patient-reported outcome scores than those without, indicating a significant burden of challenging-to-treat areas on patients' quality of life.
