A randomised phase 3b study evaluating the safety and efficacy of risankizumab in adult patients with moderate-to-severe plaque psoriasis with non-pustular palmoplantar involvement

J Am Acad Dermatol 2024;91:1150–7 doi: 10.1016/j.jaad.2024.07.1521

Lebwohl et al. investigated the efficacy and safety of risankizumab compared with placebo for treating palmoplantar psoriasis. At Wk16, significantly more patients receiving risankizumab achieved palmoplantar Investigator’s Global Assessment (ppIGA) 0/1 and PPASI75. The results were sustained through Wk52 with no new safety signals.

Secukinumab Reduces Psoriasis-associated Pruritus and Regenerates the Cutaneous Nerve Architecture: Results from PSORITUS a Doubleblind, Placebo-controlled, Randomized Withdrawal Phase IIIb Study

Acta Derm Venereol. 2024 20;104:adv40737 doi: 10.2340/actadv.v104.40737

Renkhold et al. report that secukinumab significantly reduced psoriasis-associated pruritus intensity, improved skin lesions, and normalised histopathological changes, with stable neuroanatomy despite treatment discontinuation.

Sustained response to guselkumab regardless of baseline characteristics in patients with active psoriatic arthritis and inadequate response to TNF inhibitors: results from the phase 3b COSMOS clinical trial

RMD Open. 2024 Dec 12;10(4):e004494. doi: 10.1136/rmdopen-2024-004494.

McInnes et al. assessed the efficacy of guselkumab over 48 weeks in patients with psoriatic arthritis who had an inadequate response to TNF inhibitors. The results demonstrated consistent improvements in joint, skin, and patient-reported outcomes across all baseline-defined subgroups. Guselkumab showed greater efficacy compared with placebo at Week 24, with responses maintained or improved through Week 48.

Indirect comparison of deucravacitinib and other systemic treatments for moderate to severe plaque psoriasis in Asian populations: A systematic literature review and network meta-analysis

J Dermatol. 2024;51:1559–1571 doi: 10.1111/1346-8138.17448

Tsai et al. conducted a systematic literature review and network meta-analysis evaluating deucravacitinib and other systemic treatments for moderate-to-severe plaque psoriasis in Asian populations. The authors reported that deucravacitinib achieved PASI75 and PASI90 response rates of 66% and 40%, respectively, higher than placebo and apremilast.

Interleukin-23 vs. interleukin-12/23 inhibitors on preventing incidental psoriatic arthritis in patients with psoriasis? A real-world comparison from the TriNetX Global Collaborative Network

J Am Acad Dermatol 2024 Nov;91:889–895 doi: 10.1016/j.jaad.2024.07.1473

Tsai et al. observed no significant difference in the incidence of psoriatic arthritis among psoriasis patients treated with IL-23 inhibitors compared to IL-12/23 inhibitors, although there was a numerically lower PsA risk with IL-23 inhibitors. Results indicate both therapies are similarly effective for PsO management.

Persistent patient-level effect of guselkumab at consecutive 8-week dosing visits and over time in patients with active psoriatic arthritis: post hoc analysis of a 2-year, Phase 3, randomized, controlled study

ACR Open Rheumatol. 2024 doi 10.1002/acr2.11732 Epub ahead of print

Mease et al. conducted a post-hoc analysis of the phase 3 DISCOVER-2 trial to assess the persistence of clinically relevant improvements with guselkumab in biologic-naïve patients with PsA. The analysis showed that guselkumab maintained clinical improvements in joint and skin domains at consecutive dosing visits (Q8W) and over time.

Development of extra-musculoskeletal manifestations in upadacitinib-treated patients with psoriatic arthritis or axial spondyloarthritis

Arthritis & Rheumatology 2024. Epub ahead of print doi: 10.1002/art.43069

Poddubnyy et al. analysed five clinical trials to evaluate extra-musculoskeletal manifestations (EMMs) like uveitis, IBD, and psoriasis in patients treated with UPA. They observed low incidences across PsA, r-axSpA, and nr-axSpA. Numerically, uveitis rates were lower in
UPA-treated patients than in those receiving placebo, particularly in r-axSpA.

Effect of apremilast on hand and whole-body MRI assessments of inflammation in patients with psoriatic arthritis (MOSAIC): a phase 4, multicentre, single-arm, open-label study

Lancet Rheumatol. 2024 Doi: 10.1016/S2665-9913(24)00232-7

Østergaard et al. conducted a phase 4 multicentre, single-arm, open-label study to evaluate the effect of apremilast on MRI-assessed inflammation in PsA patients using PsAMRIS and MRI-WIPE. The study demonstrated that apremilast reduced inflammation in joints and entheses with no structural damage progression. The study also supports the use of MRI as an objective tool in PsA trials.

Deucravacitinib, a selective, TYK2 inhibitor, in psoriatic arthritis: Achievement of minimal disease activity components in a phase 2 trial

Rheumatology (Oxford). 2024:keae580 doi: 10.1093/rheumatology/keae580

Kavanaugh et al. conducted a post hoc analysis of a phase 2 trial examining deucravacitinib in patients with active psoriatic arthritis, focusing on the achievement of MDA components.

The analysis demonstrated that treatment with deucravacitinib led to a higher proportion of patients meeting each MDA component compared with placebo at 16 weeks.

A comparison of the safety and efficacy of tapinarof and roflumilast topical therapies in the management of mild-to-moderate plaque psoriasis

Skin Res Technol. 2024 Sep;30:e70041 doi: 10.1111/srt.70041

Ghani et al. compared the efficacy and safety profiles of tapinarof and roflumilast for treating mild-to-moderate plaque psoriasis. Both therapies showed robust efficacy and were well-tolerated, with low rates of adverse events. Tapinarof exhibited marginally higher efficacy in PASI scores compared to roflumilast.
