This study examined real-world etanercept and adalimumab treatment patterns in patients with psoriasis, psoriatic arthritis, or both.This retrospective analysis utilized data from patients with psoriasis, psoriatic arthritis, or both from a large, US claims database. Outcome measures included persistence on index therapy; pauses (7-59 days) and gaps (≥60 days) in therapy; and rates of discontinuing, switching and restarting index therapy in nonpersistent patients.Of 4,453 patients, 2,534 initiated etanercept and 1,919 initiated adalimumab. In psoriasis patients (n = 2,775), 46.4% and 56.8% on etanercept and adalimumab, respectively, were persistent for ≥12 months, 49.0% and 56.3% discontinued, 23.8% and 22.4% restarted and 14.9% and 11.3% switched index therapy within 12 months. In psoriatic arthritis patients (n = 1,197), 60.7% and 63.3% on etanercept and adalimumab, respectively, were persistent for ≥12 months, 48.3% and 51.6% discontinued, 25.8% and 20.0% restarted and 16.5% and 17.9% switched index therapy. In patients with both (n = 481), 58.1% and 59.6% on etanercept and adalimumab, respectively, were persistent for ≥12 months, 42.7% and 63.2% discontinued, 24.3% and 12.6% restarted and 21.4% and 15.8% switched index therapy.Treatment modifications were common in patients with psoriasis, psoriatic arthritis, or both within 12 months of initiating etanercept or adalimumab.

Objectives: The objective of this study was to calculate adherence, persistence and 10-year switches in patients with PsA, by comparing adalimumab and etanercept in real life.Methods: The authors conducted a retrospective, observational, pharmacological and non-interventional study taking into consideration the dispensations of the study drugs at the Hospital Pharmacy, from 1 January 2007 to 31 December 2018. In the study, the authors considered adalimumab and etanercept. The authors calculated adherence to treatment through the relationship between received daily dose (RDD) and prescribed daily dose (PDD), and calculated persistence to treatment as the difference in days between the first and last dispensation.Results: The authors enrolled 113 patients, 60 treated with adalimumab and 53 with etanercept. Adherence levels were 0.83 for adalimumab and 0.84 for etanercept. Switches occurred in 42% of adalimumab and in 47% of etanercept prescriptions.Conclusion: In the treatment of PsA, persistence and switches are a problem for patients who cannot follow a consistent therapy over time, for clinicians who have to manage therapy suspension and changes, and for the National Health System that must procure and pay for a high number of drugs without information on their real value in terms of efficacy and safety of use.

The aim of this study was to evaluate medication adherence and persistence of patients treated with Etanercept and Adalimumab for Rheumatoid Arthritis, also giving economic evaluations on therapy costs for Received Daily Dose (RDD).This retrospective study took into account 6 years from January 1, 2007 to December 31, 2012. Medication adherence was quantified utilizing the ratio between RDD and Prescribed Daily Dose (PDD). Persistence has been reckoned taking into account the actual days of therapy comparing posology with supplied dose. The persistence has been graphed according to Kaplan-Meier method. The cost per RDD was reckoned starting from the expense incurred by Pescara General Hospital.Medication adherence gave results in values between 0.88-0.97 for Etanercept and 0.83-0.90 for Adalimumab. The value of persistence was 100% for Etanercept and 90% for Adalimumab for the first year, and 70% for Etanercept and 80% for Adalimumab for the second year. In the 3rd year the persistence for Etanercept was 50% while for Adalimumab it was 60%. In the fourth year the persistence for Etanercept was 21% while for Adalimumab it was 27%. The statistical analysis was conducted using the Log rank test. The average cost per RDD was €32.97 for Etanercept and for Adalimumab it was €32.00 as an average of 6 years.The medication adherence was good for both Etanercept and Adalimumab. The rate of persistence decreased strictly in the fourth year of treatment. This data suggests the need for continuous monitoring of patients in treatment with TNF blockers.

Abstract Background: Etanercept and adalimumab are the most widely used biologic agents for psoriasis today. Large phase III trials have elucidated the much higher efficacy of adalimumab over etanercept; however, no head-to-head comparison data exist for these two medications. Objective: We report four cases of patients well controlled with Enbrel who flared when switched to adalimumab. In all four cases, the patient's psoriasis improved when switched back to etanercept. Conclusion: This brief report is intended to alert clinicians of the possibility that, despite the well-known average efficacy advantage of adalimumab over etanercept, some psoriasis patients experience better clinical outcome with etanercept than adalimumab. Therefore, despite the general efficacy difference between these two TNF inhibitors, it may be worth keeping in mind etanercept as an option in patients who have failed with adalimumab.Key words:: adalimumabEnbreletanerceptHumirapsoriasis Declaration of interest: Dr Bhutani has no financial conflicts of interest to report.

This retrospective multicentre analysis from the Psoriasis Registry Austria (PsoRA) was conducted to determine drug effectiveness and survival of anti-tumour necrosis factor alpha (anti-TNF-α) agents in patients with moderate-to-severe chronic plaque psoriasis over a 9-year period. Data on 1,019 treatment cycles with adalimumab (n = 460), etanercept (n = 501), and/or infliximab (n = 58) administered to 827 patients (272 women, 555 men) were available for analysis. Compared with etanercept, adalimumab and infliximab showed superior short-term effectiveness. Intention-to-treat-calculated median drug survivals for adalimumab (1,264 days) and etanercept (1,438 days) were similar to each other (p = 0.74), but significantly superior to that of infliximab (477 days) (p = 7.0e-07 vs. adalimumab and p=2.2e-07 vs. etanercept, respectively). Their drug survival rates at 36 months were 51.6%, 56.0%, and 22.6%, respectively. Survival rates correlated significantly with effectiveness for adalimumab and etanercept, but not for infliximab.

<b><i>Background:</i></b> In elderly patients the management of psoriasis is challenging due to contraindications and a higher risk of side effects. <b><i>Objective:</i></b> Our retrospective study aimed to evaluate the long-term efficacy and safety profile of subcutaneous anti-tumor necrosis factor (anti-TNF) agents in elderly psoriatic patients. <b><i>Methods:</i></b> The study included 89 patients (aged ≥65 years) with plaque-type psoriasis and psoriatic arthritis treated with the subcutaneous anti-TNF-α agents etanercept or adalimumab as monotherapy for a long-term continuous period. <b><i>Results:</i></b> Efficacy results were consistent and stable over long-term observation, as expressed by mean Psoriasis Area and Severity Index (PASI) score variation, percentage of patients achieving PASI50 and PASI75 and by the improvement of articular indices, pain visual analogue scale (Pain-VAS) and 44-Joint Disease Activity Score (DAS44-ESR). The proportion of patients achieving PASI50 was 91.80 and 82.14% at week 156 with etanercept and adalimumab treatment, respectively, while the proportion of patients achieving PASI75 was 83.61 and 71.43% at week 156 when treated with etanercept and adalimumab, respectively. The mean DAS44-ESR score decreased from 5.80 to 0.89 and from 3.43 to 1.44 at week 156 and the mean Pain-VAS score decreased from 75.10 to 3.15 and from 71.30 to 18.26 at week 156 with etanercept and adalimumab treatment, respectively. Both treatment adherence and safety profile were good. <b><i>Conclusions:</i></b> Our study demonstrates that subcutaneous anti-TNF-α agents are appropriate in the long-term management of elderly patients.
