Integrated safety analysis of tofacitinib from Phase 2 and 3 trials of patients with ankylosing spondylitis

Journal Reference: Adv Rheumatol. 2024 Dec 18;64:87 doi: 10.1186/s42358-024-00402-x

Deodhar et al. conducted a pooled analysis of Phase 2 and 3 RCT data to assess the safety of tofacitinib in AS. The results showed that tofacitinib 5 mg BID had a tolerable safety profile over 48 weeks, consistent with its use in other inflammatory conditions such as RA and PsA.

Gossec et al. demonstrated that tofacitinib significantly reduced fatigue in patients with ankylosing spondylitis, with median times to clinically meaningful improvements of 8 and 12 weeks for initial and stable improvement events, respectively. These changes were observed as early as two weeks and were more pronounced compared to placebo.

November 2024

Haraoui et al. conducted a subgroup analysis of the CANTORAL study, showing that tofacitinib effectiveness was similar in patients with or without CV risk enrichment. However, AEs, particularly in older patients (≥65 years), were more frequent in the CV+ cohort. These findings highlight the need for tailored CV risk management when treating RA with tofacitinib.

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.

Impact of treatments on fatigue in axial spondyloarthritis: a systematic review and meta-analysis

Rheumatology (Oxford). 2024 Oct 10:keae549 doi 10.1093/rheumatology/keae549 Epub ahead of print

Delcourt et al. conducted a systematic review and meta-analysis revealing that both pharmacological (DMARDs) and non-pharmacological interventions reduce fatigue in axSpA patients over short and medium terms, with greater efficacy seen when combined.

September 2024

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

Efficacy of Janus kinase inhibitors in the treatment of psoriasiform atopic dermatitis

Clin Exp Dermatol. 2024 Sep 18;49:1232-1234 doi: 10.1093/ced/llae16

Napolitano et al. conducted a retrospective analysis on patients with moderate-to-severe psoriasiform atopic dermatitis (AD) treated with JAK inhibitors, showing significant improvements in disease severity scores (EASI, P-NRS, DLQI) by Week 4, with 95% of patients achieving EASI-75 and 86% achieving EASI-90 by Week 24.

Kandeel et al. compared JAK inhibitors and TNF inhibitors in RA. JAK inhibitors demonstrated better functional improvement via HAQ-DI but showed insignificant difference in CDAI compared to TNF inhibitors; both classes had similar safety.

August 2024

Adami et al. conducted a retrospective analysis to evaluate the GC sparing effects of JAKi versus bDMARDs in rheumatoid arthritis patients. They found that JAKi therapy was associated with a significant reduction in GC dose compared with bDMARDs. This suggests that JAKi could be more effective in reducing long-term GC exposure in RA patients.

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.
