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

The outcomes of children born to mothers with autoimmune rheumatic diseases

Lancet Rheumatol 2024:S2665-9913(24)00096-1 doi: 10.1016/S2665-9913(24)00096-1 Epub ahead of print

This Series paper by Andreoli, et al. provides a comprehensive overview of the literature for pregnancy outcomes for mothers with autoimmune rheumatic disease, and provides guidance on discussing these topics with patients. They also provide a list of frequently asked questions related to pregnancy and children by women with autoimmune rheumatic diseases.

Burmester, et al. found that long-term filgotinib exposure was well tolerated in patients with moderate-to-severe active RA, with a stable rate of TEAEs over time. However, potential dose-dependent relationships for herpes zoster infections, malignancies and all-cause mortality were observed in patients aged ≥65 years, indicating the potential impact of age on the safety profile of Filgotinib. Therefore, some patients aged ≥65 years may benefit from the filgotinib 100 mg dose option.

Results of this analysis by Hernández-Cruz, et al. show that infections, herpes zoster and gastrointestinal AEs in patients with RA tended to be more frequent with JAKi treatment versus TNFi. They also found that treatment persistence was similar with JAKi and TNFi in patients with RA and axSpA, and only slightly higher for TNFi in patients with PsA.

No new safety signals were found in the three-year safety data on bimekizumab for plaque PsO. Additionally, incidence of oral candidiasis significantly decreased with each subsequent year.

Efficacy and safety of JAK inhibitors in rheumatoid arthritis: update for the practising clinician

Nat Rev Rheumatol 2024;20(2):101–115 DOI: 10.1038/s41584-023-01062-9

The observed benefit:risk ratio strongly favours JAKi use in the majority of patients, and HCPs should consider and adhere to guidance on high-risk patients where applicable. Szekanecz et al summarised the safety and efficacy of approved JAKis tofacitinib, baricitinib, upadacitinib, and filgotinib to aid in clinical decision making.

October 2023

Baraliakos, et al. present data from two Phase 3 studies, BE MOBILE 1 and BE MOBILE 2, that investigated the clinical efficacy and safety of bimekizumab in axSpA patients. They found that bimekizumab had sustained and consistent efficacy in patients with nr-axSpA and r-axSpA.

July 2023

This review by Taylor, et al. reviews the long-term safety and efficacy data for baricitinib. Results from several studies showed that baricitinib has greater efficacy and survival compared to TNF inhibitors, and that the rate of CDAI <10 for baricitinib-treated RA patients increased over the course of seven years. Data also showed that remission rates were higher in real-world evidence than in RCTs.

Mirikizumab as induction and maintenance therapy for ulcerative colitis

N Engl J Med 2023;388(26):2444–2455 doi: 10.1056/NEJMoa2207940

Mirikizumab was more effective than placebo in inducing and maintaining clinical remission in patients with moderately to severely active ulcerative colitis. D’Haens, et al. also noted that opportunistic infections and cancer developed in a small number of mirikizumab-treated patients.

Herpes Zoster en Pacientes con Artritis Inflamatorias o Colitis Ulcerosa Tratados con Tofacitinib, Baricitinib o Upadacitinib: Una Revisión Sistemática de Estudios Clínicos y Estudios de Mundo Real

Overall, this evidence supports that HZ-risk is a “class” effect of JAKi, observing a higher risk compared to other non-biologic/biologic drugs . This study aimed to systematically review the incidence of HZ among RA, PsA, AS and UC patients treated with TOFA, BARI or UPA.
