Pharmacoeconomic aspects of the targeted drugs use in psoriatic arthritis in context of the Russian healthcare system

Objective: to study the clinical and economic aspects of the use of biological disease modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs), Janus kinase inhibitors (JAKi), for the treatment of psoriatic arthritis (PsA).Patients and methods. The study included adult patients (age ≥18) with active PsA, bionaive or previously treated with bDMARDs. Comparison technologies included: adalimumab (ADA), guselcumab, golimumab, ixekizumab, secukinumab (SEC), tofacitinib (TOFA), certolizumab pegol (CZP), upadacitinib (UPA), ustekinumab, etanercept. The efficacy and safety of the bDMARDs and tsDMARDs included in the study were evaluated based on the results of a systematic search and analysis of data on the comparative clinical efficacy and safety of their use. First of all, the results of phase III randomized controlled trials of drugs that are used to treat active PsA in adult patients as active treatment compared with placebo or with another active drug, or systematic reviews with meta-analysis (MA) and network MA based on them, were considered. The period from the 12th to the 24th week after the start of therapy was taken as the time point for assessing the clinical efficacy of drugs, and the frequency of achieving the ACR20/50/70 criteria was taken as the performance indicator. Cost per responder (СpR), calculated on the basis of the cost of PsA therapy by the time a response is achieved according to the ACR20/50/70 criteria, was used as a criterion for clinical and economic efficiency and to analyze the impact on the budget.Results and discussion. The data of the performed MA indicate a significantly greater effectiveness of the analyzed bDMARDs and JAKi compared to placebo in terms of the frequency of achieving a response according to the ACR20/50/70 criteria both in the group of bionaive patients and in the group of PsA patients, previously treated with bDMARDs. There were no differences between the drugs included in the study in terms of the frequency of achieving ACR20/50/70 response during the treatment of PsA. According to the study, by the 24th week of therapy, ADA, UPA and SEC 150 mg were characterized by the lowest costs to achieve the ACR20/50/70 criteria in bionaive patients and ACR20/50 in patients who were previously treated with bDMARDs. A low CpR value was determined in cases of ADA 40 mg and UPA 15 mg use for the treatment of patients with PsA who had not previously received bDMARDs. Among interleukin inhibitors, the lowest CpR value was registered for SEC 150 mg. By the 12th week of treatment, the CpR of TOFA 5 mg was higher compared to that of UPA 15 mg. CpR indicators for achieving ACR20/50 criteria in patients who were previously treated with bDMARDs were lower in UPA 15 mg and CZP compared to other drugs.Conclusion. The results of the study demonstrate the clinical and economic feasibility of introducing different bDMARDs and JAKi into real practice of PsA treatment. At the same time, the use of original drugs is not always associated with significant costs per 1 patient who responded to treatment. In the absence of direct comparisons, real clinical practice provides important information about the relative efficacy and safety of alternative therapies in the management of PsA patients.

Strategies and resources to optimise the management of Psoriatic Arthritis patients: The CREA Project

Background and aimPsoriatic arthritis (PsA) is a chronic immune-mediated inflammatory disease that affects the musculoskeletal system and skin, and manifests heterogeneously, with a variable course. In current clinical practice, variability and limitations in its follow-up have been observed. The aim of the CREA project was to agree on strategies to improve the initial assessment and follow-up of patients with PsA in Spain. Materials and methodsA survey was conducted among a representative sample of expert rheumatologists in Spain, containing 33 questions on current clinical practice, available resources, and current limitations in the follow-up of patients with PsA. The results were discussed in regional meetings and 105 strategies were proposed and finally evaluated by 85 experts in a Delphi consensus. ResultsThe most important limitations in the follow-up of PsA were lack of consultation time, lack of nursing staff, and delays in performing imaging tests. A total of 108 strategies were proposed related to the assessment of quality of life and disease-impact indices; comorbidities and extra-articular manifestations; laboratory tests; imaging tests; physical examination and metrology; and activity and function indices. Of the total, 53 were considered highly advisable, with no regional differences in consensus values. Discussion and ConclusionsThe proposals offered in the current study are applicable to the entire country, respond to the unmet needs detected in the initial survey, form a minimum action framework, and ensure optimal follow-up of patients with PsA.

Psoriatic arthritis: prospects for the future.

Psoriatic arthritis (PsA) is a form of chronic inflammatory arthritis associated with psoriasis and a multitude of other symptoms, most commonly arthritis, dactylitis, enthesitis and axial involvement. PsA is significantly heterogeneous, with a highly variable clinical course of PsA. Patients may experience significant or mild skin and joint symptoms, with some patients developing rapidly progressing joint destruction and skin symptoms. Despite the range of symptom severity, PsA is frequently associated with significantly impaired quality of life from joint destruction, as well as chronic pain and a range of comorbidities such as depression and cardiovascular disease. Currently, there are no definitive diagnostic tests for PsA, with diagnosis remaining challenging owing to the heterogeneous presentation and course of the disease. Presently, the CASPAR criteria are often used to aid rheumatologists in distinguishing PsA from other inflammatory arthritides. Treatment options for patients have been expanded over the last two decades with the emerging clinical utility of biological therapies. However, early identification and diagnosis of patients and effective disease control remain unmet medical needs within the PsA community. In addition, predicting response to treatment also remains a challenge to rheumatologists. This review highlights the current hurdles faced by healthcare professionals in the diagnosis and management of PsA patients and provides future action points for consideration by the members of the multidisciplinary team who treat PsA patients.

Impact of obesity on quality of life, psychological status, and disease activity in psoriatic arthritis: a multi‑center study.

This article aims to evaluate the possible effect of obesity on quality of life, psychological status, and other clinical variables in Psoriatic arthritis (PsA). PsA patients have been recruited by the Turkish League Against Rheumatism-Network from various centers in Turkey in this cross-sectional study. Patients with a body mass index (BMI) ≥ of 30kg/m2 were considered obese. Differences among patients with regard to obesity status were assessed with health-related quality of life measures (PsA Quality of Life Questionnaire [PsAQoL]), psychological status (Hospital Anxiety and Depression Scale [HADS]), and disease activity parameters (the Disease Activity index for PSoriatic Arthritis [DAPSA], Disease Activity Score 28-C-reactive protein [DAS28-CRP], Bath Ankylosing Spondylitis Disease Activity Index [BASDAI], Psoriasis Area and Severity Index [PASI]), physical functions (Ankylosing Spondylitis Functional Index [BASFI], Health Assessment Questionnaire [HAQ], and Health Assessment Questionnaire for the spondyloarthropathies [HAQ-S]). Pain was assessed using visual analog scale of pain (VAS-P), and fatigue was evaluated using visual analog scale of fatigue (VAS-F) and Functional Assessment of Chronic Illness Therapy (FACIT). A total of 1033 patients with PsA, 650 (62.9%) non-obese and 383 (37.1%) obese were included in the study. The PsAQoL, HADS-Anxiety, HADS-Depression, DAPSA, DAS28-CRP, BASDAI, BASFI, HAQ and HAQ-S scores of the obese group were higher than the non-obese group (p < 0.05). VAS-P and PASI scores were similar between group of patients with and without obesity. Obese patients had higher median scores of VAS-F and FACIT than non-obese patients (p < 0.05). Linear regression analysis showed that BMI affects the quality of life, depression, and disease activity. Consequently, obesity has significant associations with higher disease activity, lower QoL, risk of anxiety, depression, and fatigue. Therefore, obesity should also be taken into account in the management of PsA patients.

Psoriatic Dactylitis: Current Perspectives and New Insights in Ultrasonography and Magnetic Resonance Imaging.

Dactylitis, one of the most typical features of psoriatic arthritis (PsA), is the diffuse swelling of the digits and is determined by the involvement of different anatomic structures, including: the subcutaneous fibrous tissue “accessory pulley” system; flexor tendons, with their related structures; the articular synovium; the small enthesis of the hands. Dactylitis is currently considered both a marker of disease activity and severe prognosis and its importance in PsA is emphasized by the inclusion in the classification criteria of PsA. This review focuses on the role of imaging in the management of PsA patients with dactylitis in clinical practice and in a research setting. Furthermore, imaging could be a valuable tool to assist in unravelling some of the underlying mechanisms of the onset and chronicization of dactylitis in PsA patients.

Long-term etanercept survival in patients with psoriatic arthritis: a multicenter retrospective analysis in daily clinical practice in Spain.

Although several randomized clinical trials and observational studies have evaluated the effectiveness, safety and drug survival of etanercept (ETN) in the treatment of psoriatic arthritis (PsA), long-term data regarding these aspects are currently scarce. For this reason, we sought to investigate the long-term survival and safety of ETN in PsA patients in 4 tertiary care Spanish hospitals over a 13-year observation period (from 2004 to 2017). The records of 85 PsA patients were reviewed. ETN showed an excellent survival profile, with rates of treatment discontinuation at 1, 3, 5 and 10years of 15, 37, 46 and 59%, respectively. In our cohort, a trend toward longer drug survival in patients with shorter disease duration and those who were treated with ETN as their first biologic agent was observed. On the other hand, combination therapy with conventional disease-modifying antirheumatic drugs did not provide greater improvement on the long-term drug survival. Only 12% of the patients reported adverse events (AEs) during therapy, being most of them of mild to moderate intensity, and in only 7% AEs led to drug discontinuation. To the best of our knowledge, the present study shows the largest follow-up period of ETN-treated population analyzed in a real-life setting, and these results demonstrate the positive safety profile and long-term effectiveness of this biologic agent in the management of PsA patients.

Indirect comparison of etanercept, infliximab, and adalimumab for psoriatic arthritis: mixed treatment comparison using placebo as common comparator

Psoriatic arthritis (PsA) is a chronic inflammatory joint disorder that is commonly associated with skin psoriatic lesions and can lead to severe disability. Current pharmacologic therapy for PsA includes TNFα-blocking agents for patients who are intolerant of or have an inadequate response to conventional disease-modifying antirheumatic drugs. Currently, there are no published randomized controlled trials providing a head-to-head comparison of the effectiveness of the three TNFα-blocking agents used most often to treat patients with PsA (adalimumab, etanercept, and infliximab). In this study, we have performed the first indirect comparison among these biologic agents, in this setting, using a mixed treatment comparison analysis of the data from pivotal trials regarding efficacy profiles of adalimumab, etanercept, and infliximab evaluated as American College of Rheumatology (ACR) 20 response. Our results suggest that etanercept is expected to provide the greatest ACR20 response among the anti-TNFα agents compared with placebo in the treatment of patients with PsA unresponsive to conventional treatments. This analysis may be relevant for clinical decision-making, hence improving the management of PsA patients.
