Treatment of patients with UC with filgotinib 200 mg was associated with an increase in clinical remission at Week 10 and Week 58. The proportion of patients with clinical remission at Week 58 was significantly greater in patients who continued FIL 200 mg therapy throughout the trial. The incidence of TEAEs was similar across all treatment groups.

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.

Effectiveness and Safety of Filgotinib in Rheumatoid Arthritis: A Real-life Multicentre Experience

Clin Exp Rheumatol 2024 doi 10.55563/clinexprheumatol/k78ug3 Epub ahead of print

This real-world observational study by La Barbera, et al. confirms that filgotinib is efficacious and safe for use in the management of RA. The authors also report that improvements in clinical and laboratory features were greater in bDMARD-naïve patients with RA.

This post hoc analysis by Curtis, et al. found that current and former smokers were more likely to switch from an anti-TNF bDMARD to a different bDMARD or JAK inhibitor in comparison to non-smokers. They also found that DAS28(CRP) ≤3.2 achievement was significantly higher after filgotinib therapy regardless of smoking status in MTX-IR, bDMARD-IR, and MTX-naïve patients.

Risk of Major Adverse Cardiovascular Events in Immune-Mediated Inflammatory Disorders on Biologics and Small Molecules: Network Meta-Analysis

Clin Gastroenterol Hepatol. 2023 Oct 9:S1542-3565(23)00767-X doi 10.1016/j.cgh.2023.09.033 Epub ahead of print

The results of this study show that anti-IL-12/23, JAK inhibitors, and anti-TNF-α were associated with slightly higher risk of MACE compared with placebo. The risk was no different between biologic treatments, and the magnitude of risk did not differ between IMID type.

Findings from post hoc analyses extend the knowledge base for radiographic benefits of filgotinib in patients with RA.

Differential Properties of Janus Kinase Inhibitors in the Treatment of Immune-mediated Inflammatory Diseases

Rheumatology (Oxford) 2023;63(2):298–308 doi 10.1093/rheumatology/kead448

JAKis differ in structure, which affects their inhibitory concentration for different JAKs.

This review by Taylor, et al. compares the pharmacological profiles of JAKis, including abrocitinib, baricitinib, filgotinib, peficitinib, tofacitinib, and upadacitinib.

The results of a Bayesian network meta-analysis by Lee and Song showed that JAK inhibitors were more likely to achieve remission and LDA in DMARD-naive RA patients than MTX. However, there were no significant differences in remission rates nor LDA rates between the JAK inhibitors investigated.

This study by Tanaka, et al. shows that filgotinib reduces peripheral protein biomarkers associated with JAK/STAT signalling, inflammatory signalling, immune cell migration, and bone resorption in RA patients. Notably, filgotinib 200 mg significantly reduced IL-6, TNF, CXCL13 levels as early as Week 4.

Reinisch, et al. show that filgotinib treatment has no effect on semen parameters for men with active inflammatory diseases. This contrasts with pre-clinical studies that showed fertility issues in male animals.
