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.

Risankizumab versus ustekinumab for moderate-to-severe Crohn’s disease

N Engl J Med. 2024 Jul 18;391(3):213-223. DOI 10.1056/NEJMoa2314585

Risankizumab was noninferior to ustekinumab with respect to clinical remission at Week 24, and superior with respect to endoscopic remission at Week 48. This study aimed to present data from SEQUENCE, a direct head-to-head trial assessing the efficacy and safety of risankizumab vs ustekinumab in patients with moderate-to-severe CD, in whom at least one anti-TNF treatment had failed.

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.

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.

Patients classified as having a high neutrophil-to-lymphocyte ratio (NLR-High) who received filgotinib 200mg + MTX/csDMARDs exhibited consistently better responses after 12 weeks across clinical trials, clinical endpoints, and PROs, compared with NLR-Low patients. Taylor et al. analysed data from the 3 FINCH trials to investigate the potential association of baseline NLR with improved clinical response to filgotinib in MTX-naïve or MTX-experienced RA populations.

In a large pool of Phase 2b/3 trial data, the incidence rate of uveitis with bimekizumab over 2034.4 patient years (PYs) remained low at 1.2/100 PYs, suggesting bimekizumab may be an appropriate treatment option for patients with axSpA and uveitis. Compared with placebo, bimekizumab had a lower incidence rate of uveitis in patients with and without a history of uveitis.

Vedolizumab, Adalimumab, and Methotrexate Combination Therapy in Crohn's Disease (EXPLORER)

Clin Gastroenterol Hepatol 2024;22:1487–96 doi: 10.1016/j.cgh.2023.09.010

This Phase 4, prospective, open-label study provides additional support for the utility of vedolizumab, adalimumab, and methotrexate combination therapy in biologic-naïve patients with newly diagnosed, moderate to high-risk Crohn's disease. Investigators examined the efficacy of this triple therapy for achieving endoscopic and clinical remission at Week 26.

Tofacitinib in acute severe ulcerative colitis (TACOS): A randomized controlled trial

Journal Reference: Am J Gastroenterol 2024;119:1365–72 doi: 10.14309/ajg.0000000000002635

A combination of tofacitinib and corticosteroids improved treatment responsiveness and decreased the need for rescue therapy in patients with acute severe ulcerative colitis (ASUC). Singh et al. investigated whether addition of tofacitinib to corticosteroids was superior to corticosteroids alone in patients hospitalised with ASUC.

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.
