Baricitinib as monotherapy for treatment of rheumatoid arthritis: analysis of real-world data

Current Medical Research and Opinion 2024;40:1993–2002 doi: 10.1080/03007995.2024.2416979.

Edwards et al. report on real-world data for baricitinib monotherapy in rheumatoid arthritis, showing significant disease activity reduction across multiple registries and observational studies. These findings reinforce the viability of baricitinib monotherapy in clinical practice for RA patients, complementing existing guidelines.

Choy et al. investigated the efficacy and safety of intensified versus standard infliximab dosing for steroid-refractory acute severe ulcerative colitis (ASUC). The study found that a first dose of 10mg/kg infliximab was not superior to the standard 5mg/kg dose in achieving clinical response by Day 7. Earlier responses were noted with dose intensification, but no significant differences were observed in remission, colectomy rates, or safety profiles by Month 3.

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.

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.

August 2024

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.

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.

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.

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.

This study by Karakas, et al. found that obesity did not affect secukinumab treatment response and drug retention in ankylosing spondylitis patients.
