Amrhein et al examined the different uptake and expulsion mechanisms of BARI and TOF in cellular assays. Different cellular uptake mechanism for BARI and TOF was observed and showed that BARI’s transport was not dependent on organic cation transporters. Results indicated TOF was exported from RASF in a MATE-1 dependent way. TOF might be exported from healthy cells, thereby not inhibiting JAK pathway in these cellsThe interaction of BARI and TOF with OCTs was investigated using quenching experime...

Concerns surrounding increased rates of PE and cardiovascular associated deaths has led to black box warnings when prescribing JAK inhibitors. As such, ongoing investigations regarding cardiovascular and VTE event risks in JAK inhibitor therapies, both clinical and real-world, are vital. Mease and colleagues consider data from clinical tofacitinib development programmes, and the ongoing real-data study A3921133. Conclusions from data analysis state that those with pre-existing cardiovascular and...

This study highlights the importance of accounting for known risk factors of RA-ILD in clinical practice. Interstitial lung disease (ILD) is an extra-articular manifestation of RA. The post-hoc investigated incidence rates of ILD in patients with RA, receiving tofacitinib 5 or 10 mg twice daily, and identified potential risk factors for ILD. This post-hoc analysis comprised a pooled analysis of patients receiving tofacitinib 5 or 10 mg twice daily or placebo from 21 Phase 1-4, and 2 long-term ex...

This SLR informed the 2019 EULAR taskforce updating recommendations for RA management. Overall, no new safety signals were reported. The known safety profile of bDMARDs was confirmed and extended to tsDMARDS. IL-6i associated lower intestinal perforation has been further confirmed, while VTE and PE concerns in JAKi treatment need further evaluation.Previous updates for the EULAR recommendations on RA pharmacological management were conducted in 2016. In this SLR safety of csDMARDs, tsDMARDs, and...

This SLR reviewed data on pharmacological treatment of PsA. Findings informed the 2019 EULAR taskforce when updating recommendations for PsA management. Overall, no new safety signals were reported. Encouragingly, LTEs of JAKi did not report any venous thromboembolic events or PEs. Efficacy was demonstrated for a range of bDMARD and tsDMARD therapies in various disease domains. Efficacy varied between PsA manifestations and between therapies. Observational data demonstrated efficacy when switchi...

This 3-year, open-label, LTE study follows PsA patients previously treated in pivotal studies OPAL Broaden and OPAL Beyond. It demonstrates maintained safety and efficacy of tofacitinib up to 36 and 30 months, respectively. No new safety concerns are highlighted. Previous P3 studies, OPAL Broaden and OPAL Beyond, demonstrated safety and efficacy of 5mg and 10mg tofacitinib BID in PsA. These patients rolled over to OPAL Balance for a period of 36 months. 686 participants were used in this interim...

This paper is based upon a long-term cohort study, namely the ANSWER cohort, an observational multi-centre registry of RA patients in the Kansai district of Japan. Analyses demonstrate a difference in observed drug retention between bDMARDs-naïve and bDMARDs-switched patients. 7 bDMARD treatments were compared in patients with no prior exposure to biologics, with abatacept showing the greatest retention rate. In patients that had switched between these same bDMARDs or to tofacitinib throughout t...

This nested cohort study found that, in Switzerland, there was a generally limited overall drug maintenance for b/tsDMARD options in RA. Using data from SCQM-RA – a prospective longitudinal registry, overall maintenance (drug survival) was calculated for TNFi, bDMARD-OMA or JAKi in patients with RA.After adjusting for potential confounding factors, there was a higher hazard of drug discontinuation with TNFi compared with tofacitinib; no significant difference was observed between non-TNF bDMARDs...

Patients with psoriatic arthritis (PsA) had similar safety profile with TOF to that of other systemic therapies in real-world settings, except for the known risk of HZ. Treatment recommendations from EULAR and GRAPPA for patients with PsA vary according to adverse prognostic risk factors, disease manifestations and responsiveness to prior treatment. Safety concerns for most PsA therapies include gastrointestinal AEs, hepatotoxicity, opportunistic infections (OIs) including TB, and SIEs. This stu...

Relative Efficacy and Safety of Tofacitinib, Baricitinib, Upadacitinib, and Filgotinib in Comparison to Adalimumab in Patients with Active Rheumatoid Arthritis

This Bayesian network meta-analysis, comparing the relative efficacy and safety of JAK inhibitors, determined BARI 4mg + MTX and UPA 15mg + MTX were the most effective. The analysis included 5451 patients with an inadequate response to MTX and active RA, from four RCTs. Relative effects were converted into a probability allowing each treatment to be ranked. BARI and UPA had significantly higher ACR20 response rates than ADA 40mg + MTX whilst TOF 5mg and FIL 200mg had comparable ACR20 response ra...
