Cai et al. demonstrated that xeligekimab significantly improved the Psoriasis Area and Severity Index (PASI) scores in patients with moderate-to-severe plaque psoriasis, with 90.7% achieving PASI 75 at week 12. Xeligekimab was well-tolerated with no unexpected safety concerns.

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.

Magro et al. evaluated histologic outcomes for mirikizumab in Crohn's disease and found that early combined histologic-endoscopic response was associated with endoscopic remission after 1 year of treatment.

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.

McInnes et al. reported that bimekizumab demonstrated sustained efficacy and safety over 52 weeks in patients with psoriatic arthritis (PsA), regardless of concomitant methotrexate (MTX) use. Both bimekizumab groups (with and without MTX) showed similar improvements in achieving ACR50 and PASI100 responses.

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.

Fleischmann et al. evaluated the long-term efficacy and safety of upadacitinib in rheumatoid arthritis patients with inadequate response or intolerance to bDMARDs over five years. The study demonstrated that upadacitinib 15 mg and 30 mg were effective in maintaining disease control, with >75% of patients achieving CDAI LDA by week 260. The safety profile remained consistent with no new issues identified.

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.

This study by Mahadevan, et al. evaluated pregnancy outcomes in patients exposed to upadacitinib during pregnancy. Rates of adverse pregnancy outcomes with upadacitinib exposure were comparable to rates observed in the general population or patients with autoimmune inflammatory diseases not receiving upadacitinib. The data were limited for in utero exposure to upadacitinib, so definitive conclusions cannot be drawn regarding the effect of upadacitinib on pregnancy outcomes.

July 2024

Results of this analysis by Blauvelt, et al. showed a low adjudicated suicidal ideation and behaviour (SIB) rate of 0.13/100 patient-years for bimekizumab, consistent with general psoriasis population ranges. Bimekizumab did not increase the risk of SIB compared to other anti-IL-17A/anti-IL-23 therapies.
