Janus Kinase Inhibitor—Tofacitinib Associated with Pemphigus: An Analysis of the FDA Adverse Event Reporting System Data
Expert Opin Drug Saf. 2023;18:1-4 doi: 10.1080/14740338.2023.2248872 Epub ahead of print
This study presents initial data suggesting an association between the use of JAK inhibitors and pemphigus. This research used the FAERS database to investigate connections between JAK inhibitor usage and the occurrence of pemphigus as an adverse event.
Efficacy and Safety of Upadacitinib in Patients with Ankylosing Spondylitis Refractory to Biologic Therapy: 1-year Results From the Open-label Extension of a Phase III Study
Arthritis Res Ther 2023; 2023;18;25(1):172 doi 10.1186/s13075-023-03128-1
The efficacy and safety of updacitinib in bDMARD-IR patients with AS were sustained through to one year in an open-label extension of the SELECT-AXIS 2 study.
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 and Safety of Upadacitinib in Patients with Active Psoriatic Arthritis and Axial Involvement: Results From Two Phase 3 Studies
Arthritis Res Ther. 2023;25(1):56 doi 10.1186/s13075-023-03027-5
Evidence from two phase 3 RCTs showed that patients with PsA and axial involvement had greater responses when treated with a once-daily oral dose of 15 mg upadacitinib versus placebo, and a similar or greater response versus adalimumab. Safety results were comparable between patients with or without axial involvement.
Opportunistic Infections Associated with Janus Kinase Inhibitor Treatment for Rheumatoid Arthritis: A Structured Literature Review
Semin Arthritis Rheum. 2023;58:152120
Structured literature review shows a varied incidence of opportunistic infections (OIs) among RA patients exposed to JAK inhibitors.
Expert Opin Drug Saf. 2022. doi: 10.1080/14740338.2022.2100343
It is too early to conclude that the second-generation JAK inhibitors have a lower VTE risk and caution in patients with VTE risk factors is required.
Safety Profile of Upadacitinib up to 3 Years in Psoriatic Arthritis: An Integrated Analysis of Two Pivotal Phase 3 Trials
Rheumatol Ther. 2022 doi: 10.1007/s40744-021-00410-z
Upadacitinib 15 mg once daily demonstrated a similar safety profile to adalimumab 40 mg every other week, except for higher rates of HZ and opportunistic infections with upadacitinib treatment in patients treated for PsA
