Cardiovascular Safety of Janus Kinase Inhibitors in Patients with Rheumatoid Arthritis: Systematic Review and Network Meta-analysis
Front Pharmacol. 2023; 8(14):1237234 doi 10.3389/fphar.2023.1237234
This meta-analysis by Wei, et al. found that JAKi therapy was not associated with a higher risk of MACE than treatment with adalimumab, abatacept, or placebo. However, a higher incidence of all-cause mortality was observed with tofacitinib treatment than with adalimumab treatment.
Differential Properties of Janus Kinase Inhibitors in the Treatment of Immune-mediated Inflammatory Diseases
Rheumatology (Oxford) 2023 doi 10.1093/rheumatology/kead448 Epub ahead of print
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.
Relative Remission and Low Disease Activity Rates of Tofacitinib, Baricitinib, Upadacitinib, and Filgotinib versus Methotrexate in Patients with Disease-Modifying Antirheumatic Drug-Naive Rheumatoid Arthritis
Pharmacology 2023 doi 10.1159/000527186 Epub ahead of print
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.
One-Year Medication Adherence and Persistence in Rheumatoid Arthritis in Clinical Practice: A Retrospective Analysis of Upadacitinib, Adalimumab, Baricitinib, and Tofacitinib
Adv Ther. 2023 doi 10.1007/s12325-023-02619-6 Epub ahead of print
This study by Bergman, et al. showed that RA patients are significantly more likely to adhere to upadacitinib within the first 12 months of prescription versus adalimumab, baricitinib, and tofacitinib. There was also a significantly lower risk of discontinuation for upadacitinib versus the other treatment prescriptions.
Efficacy of Tofacitinib on Enthesitis in Patients with Active Psoriatic Arthritis: Analysis of Pooled Data from Two Phase 3 Studies
Arthritis Res Ther. 2023 22;25(1):153 doi: 10.1186/s13075-023-03108-5
Post-hoc analysis of two tofacitinib phase three studies concludes that tofacitinib treatment resulted in improvements in enthesitis in patients with PsA, regardless of baseline location or severity.
Post-Marketing Safety Surveillance of Tofacitinib over 9 Years in Patients with Psoriatic Arthritis and Rheumatoid Arthritis
Rheumatol Ther. 2023 doi: 10.1007/s40744-023-00576-8 Epub ahead of print
The data gathered in this post-marketing surveillance study aligned with the previously established safety profile of tofacitinib, and reports were found to have consistent safety profiles in the treatment of both patient with PsA and RA. However, the results of this study should be interpreted considering the limitations of post-marketing surveillance studies.
Relationship Between Paraoxonase-1 Genotype and Activity, and Major Adverse Cardiovascular Events and Malignancies in Patients with Rheumatoid Arthritis Receiving Tofacitinib
J Rheumatol. 2023 doi 10.3899/jrheum.2023-0112 Epub ahead of print
High paraoxonase activity is associated with a significantly reduced risk of MACE and non-NMSC malignancies in white/European RA patients. The PON1 Q192R RR genotype had a significantly greater association with paraoxonase versus the QQ genotype, but had no significant association with MACE or non-NMSC malignancies.
Tofacitinib Reduces Spinal Inflammation in Vertebral Bodies and Posterolateral Elements in Ankylosing Spondylitis: Results from a Phase 2 Trial
Rheumatol Ther. 2023 doi 10.1007/s40744-023-00564-y Epub ahead of print
Tofacitinib treatment is associated with a significant improvement in CANDEN MRI scores of spinal inflammation in axSpA patients. This study by Østergaard, et al. also validates the CANDEN MRI scoring system as an approach for measuring axSpA-associated inflammatory lesions.
Pain and Inflammation as Mediators of Tofacitinib Treatment Effect on Fatigue in Patients with Ankylosing Spondylitis: A Mediation Analysis
Rheumatol Ther. 2023 doi 10.1007/s40744-023-00570-0 Epub ahead of print
Kristensen, et al. used mediation modelling to show that tofacitinib indirectly improved fatigue symptoms via back pain and morning stiffness. This study was carried out using FACIT-F- and BASDAI Q1-based models to determine the relationship between these variables.
Tofacitinib versus Methotrexate as the First-line Disease-modifying Antirheumatic Drugs in the treatment of Rheumatoid Arthritis: An Open-label Randomized Controlled Trial
doi: 10.1111/1756-185X.14801 Epub ahead of print
This single-centre study by Khan, et al. suggests that high-dose methotrexate (25 mg/week, subcutaneously) may be as efficacious as tofacitinib in patients with established RA who are DMARD naïve or have not received a therapeutic dose of DMARDs.
