Deodhar et al. evaluated the efficacy and safety of intravenous secukinumab in patients with active axial spondyloarthritis. The study found a significant improvement in the ASAS40 response at Week 16 (40.9% vs 22.9% in placebo, P<0.0001), with responses maintained through Week 52. No new safety signals were observed.

Tanaka et al. observed that in Japanese patients with rheumatoid arthritis treated with tofacitinib, those with absolute lymphocyte counts (ALCs) <0.5x10³ cells/mm³ had a higher risk of serious infections and herpes zoster events compared to patients with higher ALC levels. This threshold may help identify increased infection risk in this population

Buch et al. evaluated the efficacy and safety of filgotinib in patients with moderately active rheumatoid arthritis and inadequate response to methotrexate in the FINCH 1 study. At     Wk 12, ACR20 response rates were significantly higher with filgotinib 200 mg (77.9%) and 100 mg (67.8%) compared to placebo (43.8%). Safety profiles for both filgotinib doses were similar to adalimumab.

Efficacy of Janus kinase inhibitors in the treatment of psoriasiform atopic dermatitis

Clin Exp Dermatol. 2024 Sep 18;49:1232-1234 doi: 10.1093/ced/llae16

Napolitano et al. conducted a retrospective analysis on patients with moderate-to-severe psoriasiform atopic dermatitis (AD) treated with JAK inhibitors, showing significant improvements in disease severity scores (EASI, P-NRS, DLQI) by Week 4, with 95% of patients achieving EASI-75 and 86% achieving EASI-90 by Week 24.

Kandeel et al. compared JAK inhibitors and TNF inhibitors in RA. JAK inhibitors demonstrated better functional improvement via HAQ-DI but showed insignificant difference in CDAI compared to TNF inhibitors; both classes had similar safety.

Following discontinuation of secukinumab 150mg or 300mg, a proportion of patients sustained low PASI with clear or almost clear skin despite being drug free for up to 2 years. Patients with a shorter disease duration were less likely to relapse, further supporting the hypothesis that earlier intervention with secukinumab may result in long-term control of moderate-to-severe psoriasis.

Adami et al. conducted a retrospective analysis to evaluate the GC sparing effects of JAKi versus bDMARDs in rheumatoid arthritis patients. They found that JAKi therapy was associated with a significant reduction in GC dose compared with bDMARDs. This suggests that JAKi could be more effective in reducing long-term GC exposure in RA patients.

Pacheco et al. demonstrated that, compared with axSpA patients who respond to secukinumab,  patients who do not respond show increased IL-17A-producing cells and have a more pronounced type 1 IFN signature, indicating a larger inflammatory burden.

Deodhar et al. investigated the impact on efficacy and safety of escalating secukinumab dose from 150mg to 300mg Q4W in AS patients who did not achieve inactive disease during an initial 16-week period of 150mg secukinumab. At Week 52, clinical safety response rates were similar across groups continuing with 150mg or escalating to 300mg secukinumab.

Mease et al. assessed the comparative effectiveness of bimekizumab and risankizumab in patients with PsA over 52 weeks using a matching-adjusted indirect comparison (MAIC). The study included patients who were biologic disease-modifying anti-rheumatic drug (bDMARD) naïve or had a prior inadequate response or intolerance to tumour necrosis factor inhibitors (TNFi-IR).
