In a real-world setting, tofacitinib and baricitinib have comparable continuing efficacies and safety profiles in patients with RA. It is important to determine the differences and similarities of JAK inhibitors in a real-world setting so that the optimal agent can be administered. However, until now, no published data of a direct comparison among these agents in RA have been available. With this in mind, Iwamoto, et al. compared the efficacy and safety of tofacitinib with those of baricitinib ...

Tofacitinib versus tocilizumab in the treatment of biological-naïve or previous biological-failure patients with methotrexate-refractory active rheumatoid arthritis

Mori S, Urata Y, Yoshitama T, Ueki Y.
RMD Open. 2021;7(2):e001601.

Findings from a multicentre cohort study in Japan provide important information that is expected to aid in determining the position of tofacitinib in the treatment algorithm for RA. Mori S, et al. compared therapeutic outcomes, from real-world registries, at 12 months between tofacitinib-treated and tocilizumab-treated patients to clarify whether tofacitinib should only be considered as an option for patients who have either failed to respond to at least one bDMARD or are MTX-resistant/-intoler...

Upadacitinib Monotherapy Versus Methotrexate Monotherapy in Methotrexate-naïve Japanese Patients with Rheumatoid Arthritis: A Sub-analysis of The Phase 3 SELECT-EARLY study

Takeuchi T, Rischmueller M, Blanco R, Xavier RM, Ueki Y, Atsumi T, Chen S, Friedman A, Pangan AL, Strand V, van Vollenhoven RF.
Mod Rheumatol 2021;26:1–16.

In this sub-analysis of the Phase 3 SELECT-EARLY study, UPA demonstrated clinical efficacy superior to placebo in the Japanese subpopulation. Along with a favourable efficacy observed with the Japan-specific 7.5 mg dose of UPA for all secondary endpoints. SELECT-EARLY was designed to study the safety and efficacy of UPA 15 and 30mg as monotherapy, but it also included a subset of 138 Japanese patients, 40% of whom were randomised to receive UPA 7.5mg. This was designed to meet the requirements...

Outcomes of Dose Reduction, Withdrawal, and Restart of Tofacitinib in Patients with Rheumatoid Arthritis: A Prospective Observational Study

Mori S, Ueki Y.
Clin Rheumatol. 2019 Aug 9. DOI: 10.1007/s10067-019-04721-z

Following achievement of remission or low disease activity (LDA), a dose reduction strategy of TOF to a 5mg QD dose was preferable to immediate withdrawal of TOF, with lower relapse rates. Clinical remission or LDA early in the disease course is a target for every RA patient. Although maintaining a state of remission or LDA is beneficial to patients, the AEs and costs associated with DMARDs, have significant burdens on patients during life-long RA treatment. This long-term study was performed t...

Tofacitinib Therapy for Rheumatoid Arthritis: A Direct Comparison Study between Biologic-naive and Experienced Patients

Mori S, Yoshitama T, Ueki Y.
Intern Med. 2018 Mar 1;57(5):663-670. doi: 10.2169/internalmedicine.9341-17

This 6-month prospective direct comparison study analysed the effectiveness of tofacitinib (TOF) therapy on bDMARD-naïve and bDMARD-experienced patients. bDMARD-naïve patients were more responsive to TOF therapy than bDMARD-experienced patients. The study analysed the data of 113 patients diagnosed with high or moderate disease activity, defined using CDAI scores. All patients had failed to achieve CDAI low disease activity or remission with MTX therapy for ≥3 months. Patients were...
