Psoriatic Arthritis

Key clinical point: Nearly two out of three patients with psoriatic arthritis (PsA) had clinically significant central sensitization (CS), with the severity of psoriasis, anxiety level, and sleep quality being independent predictors of worse CS Inventory (CSI) scores.

Major finding: Overall, 65.1% patients had clinically significant CS, with a CSI score ≥ 40, with the severity of psoriasis and disease activity scores for PsA being positively associated with CSI scores (correlation coefficient 0.393-0.652; P < .001). The Psoriasis Area Severity Index (odds ratio [OR] 9.70; P = .017), General Anxiety Disorder-7 (OR 2.89; P = .014), and Insomnia Severity Index (OR 5.56; P = .041) scores were independent predictors of CS.

Study details: This cross-sectional observational study included 103 patients with PsA (age 18-75 years) with a mean CSI score of 45.4.

Disclosures: This study did not receive any financial support. The authors declared no conflicts of interest.

Key clinical point: Bimekizumab demonstrated consistent safety and sustained efficacy for up to 2 years in patients with psoriatic arthritis (PsA) who were biologic-naive or inadequately responsive to tumor necrosis factor inhibitors (TNFi-IR).

Major finding: From weeks 52 to 104, the incidence of treatment emergent adverse events (TEAE) was consistent with previous studies, with no new safety signals. SARS-CoV2 infection (18.6 per 100 patient-years) was the most common TEAE. Approximately 50% biologic-naive and TNFi-IR patients maintained a ≥50% improvement in the American College of Rheumatology response.

Study details: This open-label extension (BE-VITAL) of two phase 3 trials included biologic-naive (n = 852) and TNFi-IR (n = 400) patients with PsA who were randomly assigned to receive bimekizumab, placebo with crossover to bimekizumab at week 16, or adalimumab followed by bimekizumab at week 52.

Key clinical point: Guselkumab treatment every 4 or 8 weeks (Q4W/Q8W) showed minimal clinically important improvements (MCII) in Clinical Disease Activity Index for Psoriatic Arthritis (cDAPSA) after the first dose and sustained disease control for up to 1 year in patients with psoriatic arthritis (PsA).

Major finding: Both guselkumab doses (Q4W and Q8W) vs placebo led to early achievement of MCII in cDAPSA (hazard ratio 1.6-1.7; all P < .0001), with higher response rates at week 4 (P < .01). Achieving early MCII in cDAPSA was associated with sustained disease control at 24 and 52 weeks (odds ratio 1.4-3.5; all P < .05).

Study details: This post hoc analysis of phase 3 trials, DISCOVER-1 and DISCOVER-2, included 1120 patients with active PsA who received guselkumab (Q4W or Q8W) or placebo with a crossover to guselkumab Q4W at week 24.

Key clinical point: Treatment with biologics, such as tumor necrosis factor inhibitors (TNFi) and interleukin-17 inhibitors (IL-17i), altered serum levels of matrix metalloproteinase-3 (MMP3), S100 calcium-binding protein A8 (S100A8), acid phosphatase 5, tartrate resistant (ACP5), and CXC motif chemokine 10 (CXCL10), with initial levels of these biomarkers effectively predicting treatment response to biologics in patients with psoriatic arthritis (PsA).

Major finding: The serum levels of MMP3, S100A8, ACP5, CCL2, and CXCL10 were significantly reduced with TNFi (all P < .05), whereas ACP5 and CCL2 levels increased with IL-17i (both P < .05). The baseline levels of MMP3, S100A8, ACP5, and CXCL10 effectively predicted response to biologic treatment (area under the receiver operating characteristic curve > 0.8).

Study details: This study retrospectively analyzed data from 205 patients with PsA who did (n = 130) or did not (n = 75) receive biologics or conventional synthetic disease-modifying antirheumatic drugs and 56 patients with psoriasis without arthritis, of whom 28 patients received biologics.

Key clinical point: Patients with psoriatic arthritis (PsA) initiating biologic disease-modifying antirheumatic drugs (bDMARD) had a significantly higher risk for interstitial lung disease (ILD) than control individuals in the general population; with methotrexate co-medication not being a risk factor for ILD.

Major finding: The 5-year risk for ILD was significantly higher in patients with PsA vs individuals in the general population (adjusted hazard ratio [aHR] 4.4; 95% CI 2.8-7.0). The risk for ILD did not increase among patients with PsA who did vs did not use methotrexate as co-medication (aHR 1.0; 95% CI 0.4-2.2).

Study details: This observational cohort study included 10,919 patients with PsA and 29,478 patients with rheumatoid arthritis from five Nordic rheumatology registers (all age ≥ 18 years) who initiated bDMARD treatment, along with 362,087 control individuals from the general population.

Key clinical point: Patients with psoriatic arthritis (PsA) who were disease-modifying antirheumatic drug (DMARD)-naive or non-responders to previous conventional synthetic DMARD treatment (DMARD-failure) showed similar inflammation and structural damage on imaging.

Major finding: After adjusting for patient characteristics, structural imaging parameters including Achilles tendon structural damage and Joint Space Narrowing scores (both P > .6) were similar in DMARD-naive and DMARD-failure patients. Additionally, inflammatory imaging parameters (P > .2) showed no significant differences between the two groups, indicating that failing a DMARD was not associated with worsened imaging outcomes.

Study details: This cross-sectional study evaluated 80 patients with PsA from TOFA-PREDICT trial who were either DMARD-naive (n = 40) or DMARD non-responders (n = 40).

Key clinical point: This largest and longest safety analysis on risankizumab demonstrated its long-term safety in patients with psoriatic arthritis (PsA), consistent with previously published reports.

Major finding: The rate of treatment-emergent adverse events (AE) was 142.6 events per 100 patient-years (E/100 PY), serious AE was 8.6 E/100 PY, and AE leading to discontinuation was 1.8 E/100 PY. The rates of serious infections, cancer, major cardiovascular events, and hepatic events remained consistent or decreased in frequency through 6 months or 1 year. No additional safety concerns were reported.

Key clinical point: Switching between biologic and targeted synthetic disease-modifying antirheumatic drugs (b/tsDMARD) was common due to treatment inefficacy in patients with psoriatic arthritis (PsA), with concomitant therapies and multiple prior treatments being significant risk factors.

Major finding: Overall, 40% of patients switched between b/tsDMARD, with 85.1% switches due to treatment inefficacy. The risk for switching was not affected by b/tsDMARD type (P > .05) but increased with multiple b/tsDMARD courses (adjusted hazard ratio [aHR] 1.22; P = .010), concomitant glucocorticoids (aHR 2.05; P = .001), and sulfalazine use (aHR 2.25; P = .006). Women and those with inflammatory back pain also faced an increased risk for switching.

Study details: This longitudinal retrospective study included 141 patients with PsA (age ≥ 16 years) who were treated with b/tsDMARD.

Disclosures: This study was supported by the Instituto de Salud Carlos III, Ministry of Health, Spain, and Red de Enfermedades Inflamatorias, with co-funding from el Fondo Europeo de Desarrollo Regional. The authors declared no conflicts of interest.

Key clinical point: Patients with early oligoarticular psoriatic arthritis (PsA) treated with apremilast vs placebo showed greater disease control and minimal disease activity response with a maximum of one swollen joint and one tender joint count (MDA-Joints).

Major finding: At week 16, a higher proportion of patients receiving apremilast vs placebo achieved MDA-Joints response based on sentinel joints (33.9% vs 16.0%; P = .0008) and total joints (21.3% vs 7.9%; nominal P = .0028). No new safety signals were reported.

Study details: This phase 4 FOREMOST trial included 308 patients with early oligoarticular PsA previously treated with non-steroidal anti-inflammatory drugs or ≥2 conventional synthetic disease-modifying antirheumatic drugs and were randomly assigned to receive apremilast (n = 203) or placebo (n = 105).

Disclosures: This study was funded by Amgen. Five authors declared being employees and owning stocks of Amgen. Several authors have declared other ties with Amgen and other sources.
