Psoriatic Arthritis

Key clinical point: Concomitant methotrexate had no effect on ustekimumab immunogenicity in patients with psoriatic arthritis (PsA), with the formation of antidrug antibody (ADA) not being associated with reductions in ustekinumab safety or efficacy.

Major finding: The prevalence of ADA at week 52 was not significantly different between the ustekinumab+methotrexate and ustekinumab+placebo groups, with disease activity, treatment response, dropout rates, effect of pretreatment with methotrexate, and safety outcomes not being significantly different in patients with vs without ADA (all P > .05).

Study details: This post hoc analysis of the MUST trial included 112 patients with active PsA who were naive to ustekimumab and were randomly assigned to receive ustekinumab with concomitant methotrexate or placebo.

Disclosures: This study was funded by Innovative Medicines Initiative 2 Joint Undertaking, which received support from the European Union’s Horizon 2020 Research and Innovation Program and others. F Behrens, M Koehm, and H Burkhardt declared receiving research grants from Janssen Cilag. The other authors reported no conflicts of interest.

Key clinical point: The achievement of stringent treatment goals with secukinumab led to clinically meaningful benefits in physical function in patients with psoriatic arthritis (PsA), with secukinumab showing a protective effect on radiographic progression.

Major finding: Overall, over 2 years, a relatively small percentage of patients receiving secukinumab achieved sustained remission (REM) according to very low disease activity (LDA; 19%-24%) or Disease Activity index for PsA (DAPSA) REM (30%-36%), with those achieving DAPSA LDA+REM or DAPSA REM showing numerically greater improvement in physical function. A higher proportion of secukinumab-treated patients were non-structural progressors at 2 years irrespective of achieving sustained LDA/REM.

Study details: This was a retrospective analysis from the FUTURE 5 study including 996 patients with active PsA who were randomly assigned to receive secukinumab or placebo.

Disclosures: This study was funded by Novartis Pharma AG. Two authors declared being employees of or owning stocks/shares in Novartis, and several authors reported ties with various sources, including Novartis.

Key clinical point: Secukinumab reduced disease activity at week 12, which sustained or improved by week 52, and demonstrated a consistent safety profile in patients with oligoarticular psoriatic arthritis (PsA).

Major finding: At week 12, 50% improvement in Disease Activity Index for Psoriatic Arthritis (DAPSA50) was achieved by a higher proportion of patients treated with 300 mg or 150 mg secukinumab vs placebo-treated patients (65.2% and 44.4% vs 30.0%, respectively). DAPSA50 responses further improved with 300 mg and 150 mg secukinumab at week 52 (74.2% and 71.8%; respectively). The safety profile of secukinumab was consistent with that reported in the original trials.

Study details: This post hoc analysis of the phase 3/3b FUTURE 2-5 and MAXIMISE trials included 84 patients with oligoarticular PsA who were randomly assigned to receive 150 or 300 mg secukinumab or placebo until week 12 and 150 or 300 mg `secukinumab from week 12 to 52.

Disclosures: This study was funded by Novartis Pharmaceuticals Corporation. Some authors declared being employees and holding stocks or shares or having other ties with Novartis or others.

Key clinical point: Patients with higher platelet lymphocyte ratio (PLR) or C-reactive protein (CRP) levels were more likely to be diagnosed with psoriatic arthritis (PsA) than psoriasis vulgaris (PsV), with patients having higher pretreatment systemic inflammatory marker scores showing lower treatment persistence with conventional therapies.

Major finding: PLR (odds ratio [OR] 7.027; P  =  .040) or CRP levels (OR 3.179; P  =  .022) at the time of initial presentation were associated with a higher probability of PsA vs PsV diagnosis, with patients having higher pretreatment platelet or neutrophil counts, PLR, and systemic immune/inflammation index scores exhibiting lower treatment continuation rates for conventional systemic agents (all P < .05).

Study details: Findings are from a retrospective analysis including patients with PsA (n = 47) and PsV (n = 117) and control individuals with no history of allergy or skin diseases (n = 50).

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