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...

The results of ORAL Sequel suggest that the live zoster vaccine (LZV) may not provide adequate long-term protection in patients with RA receiving TOF. This LTE study enrolled 100 patients with RA, 14 weeks post LZV vaccination. Patients received either TOF 5 mg BID, or TOF 10 mg BID in addition to any background csDMARDs. Incidence rates and 95% CIs for HZ post-vaccination were calculated based on time to first event. Short-term varicella zoster vaccine (VZV) specific immunity was evaluated at ...

Nephrotoxicity is a key side effect of NSAIDs and DMARDs used to treat RA, while biologics can reportedly cause proliferative glomerulonephritis or crescentic glomerulonephritis. This report reviews a patient on TOF presenting IgA vasculitis as an adverse effect that fully resolved following termination of TOF.Drug induced IgA vasculitis has been previously described for anti-TNFɑ therapies, but this is the first report with JAK inhibitor therapy. This is a case report of a 67-year old woman wit...

TOF demonstrated a dose-dependent promotion of human mesenchymal stromal cell (hMSC) recruitment under hypoxia, while inhibiting recruitment under normoxia. TOF also dose-dependently enhances osteogenic differentiation of hMSCs and reduces osteoclast differentiation and activity. As people age, they are more likely to suffer from fractures and delayed bone healing, as well as degenerative joint diseases or osteoporosis. Bone metabolism and fracture healing may be negatively affected by underlyin...

Osteoimmunology In Rheumatoid and Psoriatic Arthritis: Potential Effects of Tofacitinib on Bone Involvement

Data showing that TOF can inhibit unbalanced osteoclastogenesis in RA suggests that targeting the JAK-STAT pathway can halt bone erosion, as TOF has been shown to reduce articular bone erosion in RA and PsA.The authors in this review summarise current knowledge on the relationship between the immune system and the skeleton before examining the involvement of JAK-STAT signalling in bone homeostasis while discussing the evidence on the benefit of TOF on prevention of bone involvement in RA and PsA...
