A randomized placebo-controlled trial of methotrexate in psoriatic arthritis
Rheumatology (Oxford, England), 2012
MTX is widely used to treat synovitis in PsA without supporting trial evidence. The aim of our study was to test the value of MTX in the first large randomized placebo-controlled trial (RCT) in PsA. A 6-month double-blind RCT compared MTX (15 mg/week) with placebo in active PsA. The primary outcome was PsA response criteria (PsARC). Other outcomes included ACR20, DAS-28 and their individual components. Missing data were imputed using multiple imputation methods. Treatments were compared using logistic regression analysis (adjusted for age, sex, disease duration and, where appropriate, individual baseline scores). Four hundred and sixty-two patients were screened and 221 recruited. One hundred and nine patients received MTX and 112 received placebo. Forty-four patients were lost to follow-up (21 MTX, 23 placebo). Twenty-six patients discontinued treatment (14 MTX, 12 placebo). Comparing MTX with placebo in all randomized patients at 6 months showed no significant effect on PsARC [odd...
Recommendations for the use of methotrexate in psoriatic arthritis
Reumatologia clinica, 2017
To develop recommendations for the management of methotrexate (MTX) in psoriatic arthritis (PsA), based on best evidence and experience. A group of 12 experts on MTX use was selected. The coordinators formulated 14 questions about the use of MTX in PsA patients (indications, efficacy, safety and cost-effectiveness). A systematic review was conducted to answer the questions. Using this information, inclusion and exclusion criteria were established, as were the search strategies (Medline, EMBASE and the Cochrane Library were searched). Two different reviewers selected the articles. Evidence tables were created. At the same time, European League Against Rheumatism and American College of Rheumatology abstracts were evaluated. Based on this evidence, the coordinators proposed 12 preliminary recommendations that the experts discussed and voted on in a nominal group meeting. The level of evidence and grade of recommendation were established using the Oxford Centre for Evidence Based Medic...

Objective.To evaluate the effectiveness and safety of adalimumab in patients with active psoriatic arthritis (PsA) and an inadequate response to prior therapy.Methods.Patients were treated with subcutaneous injections of adalimumab 40 mg every other week in addition to their standard antirheumatic therapies in a 12-week, open-label study. Effectiveness evaluations at Week 12 included American College of Rheumatology (ACR) and Psoriasis Area and Severity Index (PASI) response rates, Psoriatic Arthritis Response Criteria (PsARC), active dactylitis, enthesitis, and target lesion assessment. Physical function was evaluated using the Health Assessment Questionnaire Disability Index (HAQ-DI).Results.A total of 127 patients were enrolled. At Week 12, patients achieved ACR20, ACR50, and ACR70 response rates of 78.0%, 55.9%, and 21.3%, respectively. PASI50 and PASI75 response rates were 64.7% and 47.1%. A PsARC response was experienced by 70.1% of patients. Between baseline and Week 12, clin...
Trials, 2017
The introduction of anti-tumor necrosis factor medications has revolutionized the treatment of psoriasis with achievement of treatment goals (Psoriasis Area and Severity Index score 75, remission) that are not usually met with conventional systemics. Nevertheless, some patients continue to experience persistent disease activity or treatment failure over time. Strategies to optimize treatment outcomes include the use of concomitant methotrexate, which has demonstrated beneficial effects on pharmacokinetics and treatment efficacy in psoriasis and other inflammatory diseases. This is an investigator-initiated, multicenter randomized controlled trial (RCT) designed to compare the combination treatment of adalimumab and methotrexate with adalimumab monotherapy in patients with psoriasis. The primary outcome is adalimumab drug survival at week 49. Other outcomes include improvement in disease severity and quality of life, tolerability, and safety. Moreover, anti-adalimumab antibodies and ...

Introduction: In the SPIRIT-H2H (ClinicalTrials.gov: NCT03151551) trial in biologic-naïve patients with active psoriatic arthritis (PsA), ixekizumab (IXE) was superior to adalimumab (ADA) at week 24 in terms of achieving a combined endpoint of C 50% improved response in the American College of Rheumatology scale score (ACR50) and 100% improvement in the Psoriasis Areas and Severity Index (PASI100), and was non-inferior in terms of achieving ACR50. IXE resulted in similar improvements of PsA manifestations irrespective of the use of concomitant conventional synthetic diseasemodifying anti-rheumatic drugs (csDMARDs), while ADA response was higher with concomitant csDMARD use. The aim of this study was to determine the efficacy and safety of treatment with IXE and ADA with or without methotrexate (MTX), the most commonly use csDMARD, through week 52 in patients with PsA. Methods: In the open-label, rater-blinded, head-to-head SPIRIT-H2H trial, randomization of patients was stratified by concomitant use of csDMARD and moderate-to-severe plaque psoriasis involvement. In the post-hoc subgroup analysis presented here, subgroups were defined as with/without concomitant MTX use at baseline. Treatment group effects within subgroups were tested using Fisher's exact test. Missing data were imputed using non-responder imputation. Results: By week 52, IXE provided similar improvements in the combined ACR50 and PASI100 endpoint, ACR50, and other PsA-related domains regardless of whether IXE was used with or without MTX, while ADA efficacy Electronic supplementary material The online version of this article (

Objective To examine the effectiveness and 2-year retention rates of methotrexate (MTX) in MTX naïve patients with psoriatic arthritis (PsA). Methods Data on 430 patients with PsA participating in an ongoing longitudinal observational multicentre study in Norway were analysed. 1218 MTX naïve patients with rheumatoid arthritis (RA) from the same study served as a reference population. Assessments included measures of disease activity (28 joint counts, acute phase reactants), health status and utility scores. Six-month effectiveness data were compared both by crude analyses and with adjustments for age, sex and the respective baseline values. Two-year drug survival was compared by Kaplan-Meier and Cox regression analyses. Results After 6 months of MTX treatment, both patients with PsA and those with RA improved in most disease activity measures and patient reported outcomes. In the adjusted analysis, patients with PsA tended to have less improvement, but changes were in the same range as in patients with RA. Two-year retention rates of MTX therapy in patients with PsA and RA were 65% and 66%, respectively, with only minor differences in reported reasons for discontinuation. Lower age, longer disease duration and higher Modifi ed Health Assessment Questionnaire (MHAQ) score and patient global assessment were independent predictors of MTX termination within the fi rst 2 years of treatment. Conclusion In this real-life study, MTX treatment was associated with improvement in disease activity and health-related quality of life in patients with PsA after 6 months of treatment. Retention rates of MTX were similar in PsA and RA. Psoriatic arthritis (PsA) is a chronic infl ammatory joint disease prevalent in up to one-third of patients with psoriasis. 1 2 It is increasingly being recognised as a severe form of arthritis, and studies have shown that erosive progression and disability are quite frequent. 3-5 The effi cacy of tumour necrosis factor α (TNFα) inhibitors in PsA is well documented in randomised controlled trials (RCTs). 6-8 The introduction of these agents has represented major progress in the treatment of PsA and has also led to increased interest in the mechanisms and management of the disease. However, biological agents are costly and normally restricted to patients who have failed conventional therapy with one or more non-biological disease-modifying anti-rheumatic drugs (DMARDs). Thus, optimal use of DMARDs is important.

Objective.To assess the efficacy and safety of adalimumab or cyclosporine (CYC) as monotherapy or combination therapy for patients with active psoriatic arthritis (PsA), despite methotrexate (MTX) therapy.Methods.A prospective 12-month, nonrandomized, unblinded clinical trial of 57, 58, and 55 patients who received CYC (2.5–3.75 mg/kg/day), adalimumab (40 mg every other week), or combination, respectively. Lowering of concomitant nonsteroidal antiinflammatory drugs (NSAID) and corticosteroids and reductions of adalimumab and/or CYC doses in responding patients were not restricted.Results.Mean numbers of tender/swollen joints at baseline were 9.7/6.7 in CYC-treated, 13.0/7.8 in adalimumab-treated, and 14.5/9.4 in combination-treated patients, indicating lesser disease severity of patients assigned to the first group. The Psoriatic Arthritis Response Criteria at 12 months were met by 65% of CYC-treated (p = 0.0003 in favor of combination treatment), 85% of adalimumab-treated (p = 0.15...

Background: Few studies have evaluated the effectiveness of adalimumab in the real-life setting in psoriatic arthritis (PsA). Objective: To evaluate the 2-year retention rate of adalimumab in PsA patients. Potential baseline parameters influencing persistence on treatment were also evaluated. Methods: PsA patients from 16 Italian Rheumatology Units treated with adalimumab as firstor second-line biological therapy were retrospectively evaluated. Adalimumab retention rate was evaluated at 12 and 24 months. Logistic regression was used to evaluate the association between predictor variables and adalimumab retention rate. Results: From 424 patients (53.5% male, aged 48.3 ± 12.8 years) who started treatment with adalimumab, 367 (86.6%) maintained treatment for 12 months and 313 (73.8%) for 2 years. At 24-months, Disease Activity in PsA (DAPSA) remission (defined as ≤4) and Low Disease Activity (LDA) (≤14) were achieved in 22.8% and 44.4% of patients, respectively. Adalimumab treatment significantly decreased the number of tender (7.0 ± 5.7 at baseline vs. 2.3 ± 3.5 at 24 months, p < 0.001) and swollen joints (2.7 ± 2.8 at baseline vs. 0.4 ±

To characterise the comparative effectiveness of combination therapy (a tumour necrosis factor inhibitor (TNFi) and a conventional synthetic disease-modifying antirheumatic drug (csDMARD) such as methotrexate) and monotherapy (TNFi only) for psoriatic arthritis (PsA) from a large US registry. The analysis included adult patients with PsA who were enrolled in the Corrona database (ClinicalTrials.gov, NCT01402661), had initiated a TNFi, were biologic naïve, and had a follow-up visit ≥90 days after drug initiation. The endpoints of the analysis were TNFi persistence (drug survival) and time to Clinical Disease Activity Index (CDAI) remission. All analyses were performed using propensity scoring, which were estimated using CDAI and patient sex, to control for channelling bias. Of 519 patients meeting the inclusion criteria (318 with combination therapy and 201 with monotherapy), the analysis population was 497 for TNFi persistence and 380 for time to remission. The difference between co...
