Phase 2 Trial of Anti-TL1A Monoclonal Antibody Tulisokibart for Ulcerative Colitis

N Engl J Med. 2024;391:1119-1129 doi: 10.1056/NEJMoa23140

Sands et al. demonstrated that 12-week treatment of tulisokibart, a monoclonal antibody targeting TL1A, significantly improved clinical remission rates compared to placebo in patients with moderate-to-severe ulcerative colitis.

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.

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.

Su et al. conducted a comprehensive systematic review and network meta-analysis to assess the efficacy and safety of therapies for difficult-to-treat (D2T) RA. They found that tocilizumab and rituximab had superior efficacy and safety profiles, with 8mg every 4 weeks of tocilizumab identified as the optimal therapeutic dose.

Peyrin-Biroulet et al. evaluated the efficacy and safety of etrasimod in patients with moderately to severely active isolated proctitis, demonstrating significant improvement in clinical outcomes compared to placebo. The study reported a favourable safety profile, making etrasimod a viable treatment option for this population.

van Vollenhoven et al. compared the efficacy and safety of upadacitinib monotherapy to methotrexate monotherapy over five years in methotrexate-naïve patients with rheumatoid arthritis. The study found that upadacitinib provided better long-term efficacy and higher rates of disease activity remission than methotrexate; however, it was associated with higher incidences of adverse events, particularly at the higher dose of 30 mg.

Filgotinib (FIL) 200mg was associated with numerical reductions in the number of draining perianal fistulas based on combined clinical and MRI findings compared with placebo. Reinisch et al. reported a numerically higher proportion of patients achieving the primary endpoint of a combined fistula response and/or remission at Week 24 with FIL 200mg compared with placebo.

This post hoc analysis provides additional support for the utility of risankizumab therapy in patients with moderately to severely active CD. Investigators examined the efficacy of risankizumab for providing early symptom relief, along with the prognostic value of early symptom relief for achieving future clinical and endoscopic endpoints.
