Gold et al. showed that icotrokinra showed superior clinical response rates versus PBO and deucravacitinib in Phase 3 moderate-to-severe plaque PsO trials. Authors evaluated the efficacy and safety of icotrokinra, a targeted oral peptide that selectively binds the IL-23 receptor, compared with both PBO and deucravacitinib in adults with moderate-to-severe plaque PsO.

Gooderham et al. observed that roflumilast foam, 0.3%, improved signs and symptoms of PsO on the scalp and body, including pruritus, with low rates of AEs in patients ≥12 years of age. Authors assessed efficacy and safety of roflumilast foam, 0.3%, versus vehicle administered QD for 8 weeks in patients with PsO of the scalp and body.

Merola et al. showed that the safety profile of ixekizumab (IXE) supports its long-term use in patients with PsO, PsA, or axSpA, without an increased risk for malignant neoplasm development. Merola et al. investigated the incidence rates of malignant neoplasms among patients with PsO, PsA, or axSpA who underwent long-term treatment with IXE, an IL- 17A antagonist.

February 2025

Armstrong et al. evaluated the long-term safety and efficacy of deucravacitinib in patients with moderate to severe plaque psoriasis over a three-year period. The study found that exposure-adjusted incidence rates of AEs remained stable or declined over time, with no new safety signals emerging. Clinical response rates, including PASI75/90, were maintained, supporting the drug’s long-term efficacy.

Phase 3 trials of ixekizumab in moderate-to-severe plaque psoriasis

N Engl J Med 2016;375:345–56. doi: 10.1056/NEJMoa1512711

Gordon, et al. pool the results of UNCOVER-1, UNCOVER-2, and UNCOVER-3 to show that ixekizumab increases the proportion of patients achieving an sPGA score of 0/1 or PASI 75 versus placebo. Adverse events related to ixekizumab treatment included neutropenia, candidal infections, and inflammatory bowel disease.

Guselkumab demonstrated superiority to adalimumab and placebo in treating PsO in this Phase 3 study. Improvements in IGA and PASI scores were observed as early as Week 16 and were maintained up to Week 48. Incidence of adverse events was similar across both treatment groups.

Bimekizumab was more efficacious than ustekinumab and placebo in the treatment of moderate to severe plaque psoriasis. Previous bimekizumab Phase 2 clinical studies have shown both rapid and durable clinical improvements in skin clearance, as well as a safety profile in line with expectations from this MoA. This study aimed to evaluate the efficacy and safety of bimekizumab in moderate to severe plaque PsO over 1 year compared with both placebo and ustekinumab.

Here, the authors reported risankizumab to be both efficacious when compared to both placebo and ustekinumab in the treatment of moderate to severe plaque PsO. This publication aimed to describe two Phase 3 replicate studies, UltiMMa-1 and UltiMMa-2, which assessed the efficacy and safety of risankizumab compared with placebo or ustekinumab in patients with moderate-to-severe chronic plaque PsO.

Bimekizumab versus adalimumab in plaque psoriasis

N Engl J Med 2021; 385:130–41. doi: 10.1056/NEJMoa2102388

Bimekizumab was noninferior and superior to adalimumab with respect to PASI 90 response and IGA score at Week 16. Bimekizumab is a promising IL-17A/F inhibitor that has shown clinical improvement in PsO patients compared to placebo and other IL inhibitors. Warren et al. compared the safety and efficacy of bimekizumab with adalimumab in a 56-week double-blind trial.

This Phase 3 study by Strober, et al. reports deucravacitinib superiority to placebo and apremilast in patients with PsO. The authors found that deucravacitinib had significantly higher rates of PASI 75 and sPGA achievement than placebo and deucravacitinib.
