Retention Rate of Ixekizumab in Psoriatic Arthritis: A Real-World Study. J Pers Med 2024; 14:716. [PMID: 39063970 PMCID: PMC11278385 DOI: 10.3390/jpm14070716] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2024] [Revised: 06/26/2024] [Accepted: 07/01/2024] [Indexed: 07/28/2024] Open
Abstract
We aimed to examine the drug retention rate (DRR) of the interleukin-17 inhibitor ixekizumab in a real-world monocentric cohort of psoriatic arthritis (PsA) patients and to assess the predictors of drug discontinuation. Consecutive PsA patients who underwent treatment with ixekizumab from October 2019 to February 2023 were enrolled in this observational, retrospective, monocentric study. Clinical records were assessed at baseline and throughout the follow-up period. We collected sociodemographic data, smoking habits, body mass index, the presence of Human Leukocyte Antigen B27, comorbidities, disease involvement and duration, previous therapy, discontinuation of ixekizumab, reasons for discontinuation, and adverse events (AEs). DRR was evaluated as time to drug discontinuation and assessed through Kaplan-Meier curves. Baseline factors predicting drug discontinuation were investigated through logistic regression models. Eighty PsA patients were included in this study. Ixekizumab was administered at a dose of 160 mg by subcutaneous injection at baseline, followed by 80 mg every four weeks thereafter. Ixekizumab had a 38-month-cumulative DRR of 43.8%, accounting for both inefficacy and AEs. When considering only inefficacy, the DRR was 62.6%. Comorbidities (p = 0.665), obesity (p = 0.665), smoking (p = 0.884), disease duration ≤ 2 years (p = 0.071), axial (p = 0.131) and skin involvement (p = 0.460), and previous therapies, including conventional synthetic (p = 0.504) and biological (p = 0.474) Disease-Modifying Antirheumatic Drugs (bDMARDs), as well as the number of previous bDMARDs or targeted synthetic Disease-Modifying Antirheumatic Drugs (tsDMARDs), did not significantly affect the DRR (p = 0.349). Multivariate analysis found no independent predictors of drug discontinuation. The most frequent AEs leading to discontinuation were skin reactions; no severe infections were observed. In our real-world study, comorbidities, disease duration, and previous therapies did not affect the DRR of ixekizumab. Ixekizumab had a favorable safety profile, with no severe AEs observed.

Real-World Persistence and Treatment Patterns in Patients with Psoriatic Arthritis Treated with Anti-IL17 Therapy in Spain: The PerfIL-17 Study. Adv Ther 2023; 40:5415-5431. [PMID: 37804475 PMCID: PMC10611868 DOI: 10.1007/s12325-023-02693-w] [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: 07/28/2023] [Accepted: 09/22/2023] [Indexed: 10/09/2023]
Abstract
INTRODUCTION Given the growing interest and use of interleukin-17 inhibitors (anti-IL17) for the treatment of psoriatic arthritis (PsA), an observational study has been conducted to characterize the patient profile, treatment patterns, and persistence of ixekizumab or secukinumab in patients with PsA receiving them as first anti-IL17. METHODS This is a multicenter retrospective study, conducted at eight Spanish hospitals where data from adult patients with PsA were collected from electronic medical records. Three cohorts of patients, initiating treatment with an anti-IL17 [secukinumab 150 mg (SECU150), secukinumab 300 mg (SECU300), or ixekizumab (IXE)] between January 2019 and March 2021, were included. Demographic and clinical patient characteristics, treatment patterns, and persistence were analyzed descriptively. Continuous data were presented as mean [standard deviation (SD)] and categorical variables as frequencies with percentages. Persistence rates at 3, 6, and 12 months were calculated. RESULTS A total of 221 patients with PsA were included in the study [SECU150, 103 (46.6%); SECU300, 38 (17.2%); and IXE, 80 (36.2%)]. Treatment patterns differed by clinical characteristics: SECU150 was initiated more frequently in patients with moderate PsA and less peripheral joint involvement, while patients on SECU300 included those with a higher rate of enthesitis and active skin psoriasis, and patients on IXE showed a longer time since PsA diagnosis, more frequent comorbidities, joint involvement, and diagnosed skin psoriasis. Conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) were previously administered in 88.2% of patients and biologic or targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs) were administered in 72.9%. The mean number of previous b/tsDMARDs was 2.4 (SD 1.5) in the IXE cohort, 1.7 (SD 0.9) in the SECU300 cohort, and 1.6 (SD 1.0) for those in the SECU150 cohort. The global persistence on all anti-IL17 was 97.2%, 88.4%, and 81.0% at 3, 6, and 12 months, respectively. The most frequent reason for discontinuation across the three cohorts was lack of effectiveness (16.7%; 37/221). CONCLUSIONS Most of the patients with PsA treated with anti-IL17 in Spain had moderate to severe disease activity, high peripheral joint and skin involvement, and had received previous b/tsDMARDs. More than 80% of patients with a 1-year follow-up persisted on anti-IL17, with the highest rate observed in the IXE cohort, followed by the SECU150 then SECU300 cohorts.

Persistence and Use of Ixekizumab in Patients with Psoriatic Arthritis in Real-World Practice in Spain. The PRO-STIP Study. Rheumatol Ther 2023; 10:1319-1333. [PMID: 37481752 PMCID: PMC10468471 DOI: 10.1007/s40744-023-00584-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Accepted: 06/30/2023] [Indexed: 07/25/2023] Open
Abstract
INTRODUCTION Ixekizumab (IXE) is an IgG4-type monoclonal antibody targeting IL-17A indicated alone or in combination with methotrexate, for the treatment of active psoriatic arthritis (PsA) in adult patients with insufficient response or with intolerance to one or more disease-modifying anti-rheumatic drug (DMARD) therapy. The PRO-STIP study aimed to describe persistence, patient characteristics, treatment patterns, and effectiveness in patients with PsA receiving IXE in a real-world clinical setting in Spain. METHODS This was an observational, multicentric, retrospective, longitudinal study in adult PsA patients who started IXE between January 2019 and December 2020, with at least 24 weeks of follow-up. A descriptive analysis of patient characteristics and treatment patterns was performed. The primary objective, treatment persistence, was estimated by Kaplan-Meier survival curve. Effectiveness was evaluated by Disease Activity in Psoriatic Arthritis (DAPSA) scores at baseline and at 12 and 24 weeks. RESULTS Eighty-nine patients met the selection criteria (55.1% women and mean age 51.5 years). The median time from PsA diagnosis to starting IXE was 7.7 years (IQR 3.4-14.6). Prior to IXE, 95.5% patients had been treated with at least one biologic or targeted synthetic DMARD (b/tsDMARD). The observed persistence rates were 95.5%, 84.3% and 68.5% at 24, 48, and 104 weeks, respectively. The median persistence was not reached in the study period (mean persistence, 86.9 [95% CI 80.6-93.2] weeks). Twenty-eight (31.5%) patients discontinued IXE, 19 patients (21.3%) due to loss of effectiveness and two patients (2.2%) due to adverse events. In patients receiving treatment and with available effectiveness assessment (n = 24), DAPSA decreased significantly from baseline 23.7 (95% CI 19.5-27.9) to 14.8 (95% CI 10.5-19.2) at 12 weeks (p = 0.005) and 14.3 (95% CI 11.1-17.4) at 24 weeks (p = 0.004). CONCLUSIONS PsA patients treated with IXE in a real-world setting show high treatment persistence through 104 weeks and improvements in disease activity after treatment initiation. This suggests that IXE could be an effective treatment for patients with PsA. RETROSPECTIVELY REGISTERED Date of registration: 25th May 2021.

Real-world treatment patterns and use of adjunctive pain and anti-inflammatory medications among patients with psoriatic arthritis treated with IL-17A inhibitors in the United States. J Manag Care Spec Pharm 2023; 29:24-35.

Abstract
BACKGROUND: Much of the current research on treatment patterns and use of adjunctive pain and anti-inflammatory medications among patients living with psoriatic arthritis (PsA) predates the approval and uptake of IL (interleukin)-17A inhibitors. OBJECTIVE: To compare real-world treatment patterns and use of adjunctive pain and antiinflammatory medications between patients with PsA initiating the IL-17A inhibitors, ixekizumab and secukinumab, in a US-managed care population. METHODS: We conducted a retrospective cohort study using the HealthCore Integrated Research Database. Patients with a PsA diagnosis who initiated ixekizumab or secukinumab treatment between December 1, 2017, and November 30, 2019, were identified. Two cohorts were created based on which of the 2 medications was initiated (index date), and patients with prior use of either drug were excluded, as were patients with ankylosing spondylitis. Patients had to be continuously enrolled in the health plan for 6 months prior to (baseline) and 12 months after the index date (post-index). Inverse probability of treatment weighting was used to minimize confounding from baseline demographic and clinical differences between cohorts. Treatment patterns (dosing, persistence, discontinuation, and switching) and use of adjunctive pain/anti-inflammatory medications were assessed and compared between weighted cohorts using chi-square and t-tests. RESULTS: In total, 407 patients were identified in the ixekizumab cohort (mean age 51.6 years; 54% female) and 1,508 patients were identified in the secukinumab cohort (mean age 50.1 years; 59% female). Prior to weighting, presence of a psoriasis diagnosis code (ixekizumab: 60% vs secukinumab: 45%; standardized difference [std diff] = -0.30), specialty of the index prescriber (std diff = 0.38), and mean number of prior advanced therapies (2.0 vs 1.5; std diff = -0.33) were different between cohorts. Cohorts were well balanced after weighting. The majority of secukinumab patients (71%) received an index dose of 300 mg. Rates of persistence (ixekizumab: 40% vs secukinumab: 43%; P = 0.411) and switching (25% vs 20%; P = 0.072) were not statistically different between cohorts. Use of new adjunctive pain and anti-inflammatory medications was not statistically different between cohorts either (ixekizumab: 63% vs secukinumab: 58%; P = 0.187). CONCLUSIONS: Real-world treatment patterns and use of adjunctive pain and anti-inflammatory medications were similar in patients with PsA initiating ixekizumab and secukinumab in this US-managed care population. Further research examining reasons for discontinuation, switching, and use of adjunctive medications may help inform treatment decisions for patients living with PsA.

Abstract
INTRODUCTION Psoriatic arthritis (PsA) is a chronic arthritis typically associated with cutaneous psoriasis (PsO). Its pathogenesis is connected to an innate and acquired immune response, as well as genetic risk alleles. The extent of immunopathogenic mechanisms and the heterogenicity of clinical manifestation make the identification of patient-targeted therapies a critical issue, and the treatment decision challenging in patients' management. AREAS COVERED This review includes a brief overview of biological and small-molecule therapies, focusing on evidence from clinical trials and real-world data that support their use in PsA. We summarize novel and future possible therapeutic strategies, the importance that comorbidities have on selection of therapy and discuss the adverse event of each drug. Relevant papers for up to 1 August 2022 (trials, real-life studies, and reviews) regarding biologics and/or small molecules were summarized. EXPERT OPINION In recent years, the treatment of PsA has been revolutionized by new targeted therapies, which offer the opportunity to perform a tailored-tail management, considering risk factors, comorbidities, and the different PsA phenotypes. Growing experience with these new agents allows novel treatment approaches that may improve clinical outcomes for PsA patients, in terms of remission/low disease activity and quality of life.

Abstract
INTRODUCTION Real-world pharmacoutilization analysis of biological drugs in psoriatic arthritis (PsA) patients with the aim to evaluate biologic treatment patterns and pharmacoutilization among patients with PsA in Italy. METHODS A retrospective study was conducted using administrative databases of Italian Entities. PsA patients were included and diagnosed by hospitalization and/or an active exemption code. Two analyses were performed: a cross-sectional for treatment patterns in patients enrolled among 2017-2020, and a longitudinal study during 2015 to investigate the pharmacoutilization, in terms of persistence and monthly maintenance dosage of biological/targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARDs). Patients with or without b/tsDMARDs prescriptions before inclusion were defined as bioexperienced or naïve, respectively. An analysis on ixekizumab-treated patients (IXE patients) from the 2017-to study ending was performed. RESULTS PsA was diagnosed in 24,786 (2017), 27,221 (2018), 28,889 (2019), and 29,292 (2020) patients. Across 2017-2020, 31.1-40.5% of PsA patients were untreated with systemic medications, and 16.4-18.8% were under biological therapies. Among b/tsDMARD-treated patients, decreasing use of TNF-inhibitors (77.6-57.1%) and increasing IL-inhibitors (19.6-33.2%) was found across 2017-2020, respectively. Persistence to TNF-inhibitors and IL inhibitors as first-line ranged, respectively, 74.9-83.0% and 73.0-84.6%; specifically, 73.1-76.9% and 73.0-83.8% among bio-naïve, 83.3-90.0%, and 87.0% among bio-experienced. Among IXE-patients (N = 178), 55.6% were bio-naïve, while 21.9% previously used secukinumab, 12.9% adalimumab, 10.1% etanercept. During a 1-year follow-up, 6.8% of IXE patients switched therapy. CONCLUSIONS This real-world study of PsA pharmacoutilization in Italy showed that more than one-third of patients were systemically untreated, and almost 20% were receiving biological medications. Among biological users, increasing use of IL-inhibitors and a decrease in TNF-inhibitors prescriptions over the years were found. A rather-high extent of persistency in treatment was observed. A focused analysis on IXE patients revealed over half of them to be bio-naïve, while around one-fourth were bio-experienced to IL inhibitors.
