Minimal disease activity is a stable measure of therapeutic response in psoriatic arthritis patients receiving treatment with adalimumab.

ABSTRACT: Objective:The aim of this study was to evaluate minimal disease activity (MDA) assessments in patients with PsA during routine clinical care. Methods:We used data from a multicentre observational study of patients with active PsA who initiated treatment with adalimumab during routine clinical practice and continued treatment for at least 6 months to evaluate achievement of MDA, individual MDA criteria (modified to conform to study assessments) and ACR responses during 24 months of therapy. Pearson correlation coefficients were used to evaluate the association between MDA and individual criteria at month 6; regression models were used to determine the influence of baseline MDA criteria on achievement of MDA at month 6. Results:A total of 1684 patients were included in these analyses; most had long-standing disease. MDA was achieved by 597 patients (35.5%) at month 6. This proportion increased to 45.5% at month 24 in patients remaining on therapy. MDA status was stable over time; >75% of patients with MDA at month 6 recorded MDA at subsequent visits. Pain was the most difficult individual criterion to achieve, and enthesitis was the least difficult. Higher functional status and fewer tender joints at baseline predicted achievement of MDA at month 6. About half of patients (51.5%) with an ACR20 response at month 6 achieved MDA. Conclusion:In this observational cohort of patients with long-standing disease, MDA provided a stable and valid assessment of clinical status over 24 months.

Project description:IntroductionThe aim of this work is to characterize which Minimal Disease Activity (MDA) domains are mainly achieved, based on different treatments, in psoriatic arthritis (PsA) patients. Moreover, the association between MDA achievement and the different treatment groups was assessed.MethodsWe conducted a cross-sectional analysis of two longitudinal PsA groups. Inclusion criteria were: age ≥ 18 years, PsA diagnosis, stable treatment for at least 6 months. Patients were grouped depending on the therapy: group 1: Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)/cyclooxygenase 2 inhibitors (COX2i)/steroids, group 2: conventional synthetic Disease-Modifying Anti-Rheumatic Drugs (csDMARDs), group 3: Tumor Necrosis Factor α inhibitors (TNFi), group 4: interleukin inhibitors (IL)12-23i or IL-23i, group 5: IL-17i, group 6: phosphodiesterase 4 inhibitors (PD4i). For each group, the achieved domains based on therapy were assessed. Multivariate logistic regression analysis was performed to assess the association between the treatment groups and the MDA achievement.ResultsA total of 220 patients were enrolled, and MDA was achieved in 45.8% of them. In all treatment groups, the first MDA domains achieved were: body surface area ≤ 3, swollen joint count ≤ 1 and Leeds Enthesitis Index ≤ 1, while MDA domains less frequently achieved were Patient Global Assessment (PtgA) ≤ 2 cm and pain on visual analogue scale ≤ 1.5 cm. The logistic regression analysis showed higher odds ratios for the achievement of the MDA in those patients in groups 3 and 4.ConclusionsIn each treatment group, MDA domains less frequently achieved were PtGA and pain, suggesting that "patient-driven domains" are still an unmet need. Due to the study design and the low number of patients in some groups, it is not possible to clearly define which MDA domain was achieved or not based on treatment; however, it seems that some differences could be present. If larger and prospective studies confirm our preliminary results, we could move toward a personalized/domain treatment approach in PsA.

Project description:INTRODUCTION:Psoriatic arthritis (PsA) occurs in 10%-15% of people with psoriasis and accounts for 10%-20% of early arthritis clinics referral. Only a few prognostic factors of therapeutic response in patients with PsA have been identified. In the last years, the role of imaging has grown up and the European League Against Rheumatism recognised that ultrasound (US) has higher sensitivity than clinical examination to detect inflammatory disease activity. The aims of the Ultrasound in PSoriatic arthritis TREAtMent (UPSTREAM) study are to integrate clinic and US in order to inform whether US has provide an added prognostic value in PsA. METHODS AND ANALYSIS:UPSTREAM is an observational prospective cohort study enrolling patients with PsA having clinically active joint disease and starting a new course of therapy. The primary objective is to evaluate the additional value of US over clinical examination in detecting patients achieving minimal disease activity after 6 months. Data will be obtained at baseline and at standard clinical follow-up visits. Patient's clinical assessment will be performed according to the core set proposed by the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis-Outcome Measures in Rheumatology. Sonographic evaluations will be performed by expert sonographers in 42 joints, 36 tendons, 12 entheses and 2 bursae, according to a score that will be purposely developed for PsA by the US Study Group of the Italian Society for Rheumatology. The UPSTREAM study will identify clinical and US predictors of response to treatment in patients with PsA and active peripheral arthritis starting a new course of therapy. ETHICS AND DISSEMINATION:Ethic approval for this study has been obtained from the institutional review board (IRB)/independent ethics committee (IEC) Comitato Etico Lazio 1 (Prot. N 198 02-02-2017) and then locally from the IRB/IEC of each participating centre. Results will be published in relevant scientific journals and be disseminated in international conferences. Fully anonymised data will be accessible from authors upon request. TRIAL REGISTRATION NUMBER:NCT03330769; Pre-results.

Project description:BackgroundThis study examined the time to clinically meaningful response in patients with active psoriatic arthritis treated with tofacitinib, adalimumab, or placebo switching to tofacitinib.MethodsData were from two phase 3 studies, OPAL Broaden (12 months) and OPAL Beyond (6 months). Patients received tofacitinib 5 or 10 mg twice daily (BID), adalimumab 40 mg once every 2 weeks (OPAL Broaden only), or placebo switching to tofacitinib 5 or 10 mg BID at month 3. Baseline to initial response time was according to pre-defined clinically meaningful criteria on Health Assessment Questionnaire-Disability Index (HAQ-DI; ≥ 0.35-point improvement), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F; ≥ 4-point improvement), Psoriatic Arthritis Disease Activity Score (PASDAS; post-baseline score ≤ 3.2 and > 1.6-point improvement from baseline), and minimal disease activity (MDA; meeting at least 5 of 7 criteria) composite.ResultsIn OPAL Broaden, median time to initial HAQ-DI score response was 29, 53, and 30 days in patients treated with tofacitinib 5 mg BID, tofacitinib 10 mg BID, or adalimumab, compared with 162 and 112 days in patients treated with placebo switching to tofacitinib 5 or 10 mg BID at month 3, respectively. Across studies, median time to initial FACIT-F total score response was shorter in patients receiving tofacitinib 5 mg BID (31 days) vs other groups (84-92 days). Median time to initial response was approximately 11 (MDA)/6-9 months (PASDAS) in tofacitinib/adalimumab groups in OPAL Broaden.ConclusionThis analysis demonstrates tofacitinib's efficacy on most patient-reported and clinical endpoints over time and shows a shorter time to initial, clinically meaningful response in patients receiving tofacitinib vs patients switching from placebo to tofacitinib.Trial registrationClinicalTrials.gov , NCT01877668.

Project description:IntroductionThis study investigated the effectiveness of adalimumab treatment in improving Work Productivity and Activity Impairment (WPAI) in patients with psoriatic arthritis (PsA) in real-world settings in Japan.MethodsThis 24-week, single-arm, postmarketing surveillance study (2014-2017), conducted at 75 centers in Japan, enrolled adalimumab-naïve patients (paid workers, including part-time) meeting ClASsification criteria for Psoriatic ARthritis (CASPAR). The primary endpoint was improvement in overall work impairment (OWI) scores from baseline to week 24. Secondary endpoints included changes in WPAI-PsA (OWI, absenteeism, presenteeism, and activity impairment), Psoriasis Area and Severity Index (PASI), psoriatic arthritis screening and evaluation (PASE) scores, Disease Activity Scores in 28 joints using C-reactive protein (DAS28[CRP]), Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scores, Health Assessment Questionnaire-Disability Index (HAQ-DI) scores, and PASI75/90 and American College of Rheumatology (ACR) 20/50/70 rates.ResultsIn the effectiveness population (n = 106; 72.6% men; mean ± standard deviation [SD] age, 49.3 ± 10.7 years), OWI scores significantly improved (mean ± SD change, - 25.2 ± 35.3; p < 0.0001) from baseline to week 24. Other WPAI domain scores also improved significantly. Changes in OWI were significantly correlated (p < 0.0001) with PASE (r = 0.6284), DAS28(CRP) (r = 0.6059), BASDAI (r = 0.7281), and HAQ-DI (r = 0.6161) scores and were significantly influenced by previous nonsteroidal anti-inflammatory drug use (p = 0.0142), and baseline PASE (p = 0.0098), DAS28(CRP) (p = 0.0026), HAQ-DI (p = 0.0004), and BASDAI (p < 0.0001) scores. At the last evaluation, rate (95% confidence interval) of PASI 75 and 90 (n = 100) was 58.0% (47.7-67.8) and 39.0% (29.4-49.3), respectively, and that of ACR 20, 50, and 70 (n = 58) was 86.2% (74.6-93.9), 70.7% (57.3-81.9), and 53.4% (39.9-66.7), respectively. No new safety signals were observed in the safety population (n = 148).ConclusionAdalimumab treatment improved WPAI in patients with PsA. Improvements in OWI and joint symptoms were significantly associated.Trial registration numberClinicalTrials.gov identifier: NCT02414633.FundingAbbVie GK and Eisai Co., Ltd.
