Abstract
INTRODUCTION Significant advances in psoriasis treatment have taken place since the introduction of biologics. Tumor necrosis factor inhibitors were the first class of biologics approved and at that time greatly improved psoriasis treatment. However, newer biologics, directed to interleukin(IL)-23/IL-17 pathways central to psoriasis pathogenesis, have improved complete or nearly complete clearance rates and are characterized by an excellent safety profile.Real-world setting experiences have generally confirmed the results of clinical trials, but real-world data regarding newer biologics is relatively scarce. AREAS COVERED We provide an extensive review of real-world survival of biologic treatments for moderate to severe psoriasis. EXPERT OPINION There is growing and consistent evidence of higher drug survival of IL-23 inhibitors, possibly due to their favorable efficacy and safety profiles, dosing convenience and persistence of response despite treatment interruption; eventual confirmation of their potential role as modifiers of the natural history of psoriasis might provide additional reasons for therapeutic persistence of this class of biologics.

Treatment Persistence of Ixekizumab in Adults with Moderate-to-Severe Plaque Psoriasis Participating in the Canadian Patient Support Program. Dermatol Ther (Heidelb) 2022; 13:235-244. [PMID: 36436161 PMCID: PMC9823185 DOI: 10.1007/s13555-022-00853-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Accepted: 11/04/2022] [Indexed: 11/28/2022] Open
Abstract
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.

Healthcare Costs Among Patients with Psoriasis Treated with Ixekizumab Versus Secukinumab in Real-World Settings Over 24 Months. PHARMACOECONOMICS - OPEN 2022; 6:871-880. [PMID: 36155891 PMCID: PMC9596621 DOI: 10.1007/s41669-022-00365-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Accepted: 08/08/2022] [Indexed: 06/16/2023]
Abstract
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.
