Propensity score-based inverse probability of treatment weighting shows that efficacy may differ between tofacitinib and baricitinib. Miyazaki, et al. compared the efficacy and safety of the two JAK inhibitors in real-world clinical practice, after reduction to a minimum of the selection bias, using propensity score-based inverse probability of treatment weighting, and adjustment for confounding patient characteristics. They found that tofacitinib may be less effective in patients resistant to m...
Tofacitinib could induce Hepatitis B virus (HBV) reactivation in RA patients.With previous studies having already demonstrated that RA patients using biologic agents, might experience HBV reactivation leading to acute hepatitis, hyperbilirubinemia, and death, Wang, et al. aimed to investigate HBV reactivation in patients with RA receiving tofacitinib. They found that Hepatitis B surface antigen positive patients receiving tofacitinib have a high incidence rate of HBV reactivation, which could be...
A 3.6-fold increased risk of herpes zoster (HZ) is associated with tsDMARDs, and an increased risk is associated with bDMARDs, compared with csDMARDs. It is now well known that patients with RA have an increased risk of developing herpes zoster (HZ), and that incidence rates appear to be increased with TNF and JAK inhibitors. To this end, Redeker, et al. used data from the German RABBIT Registry to compare event and incidence rates of HZ in patients with RA treated with the three different DMAR...

Post hoc analysis of the phase III FINCH study shows that filgotinib may be an alternative treatment option for patients with RA who have poor prognostic factors (PPFs), especially those not responding to standard treatment such as methotrexate (MTX).PPFs are associated with severe disease and risk for disease progression in patients with RA. Consequently, the 2019 EULAR management guidelines for RA recommend early treatment escalation for patients with PPFs who have inadequate response to first...
Real-world evidence suggests that monotherapy and combination therapy tofacitinib is an effective intervention in RA with persistence and effectiveness comparable to bDMARDs. Despite recommendations from EULAR that bDMARDs and tsDMARDs be used in combination with csDMARDs for the treatment of RA, it is estimated that up to a third of patients take their medication as monotherapy.This post hoc analysis of data from the Australian OPAL study by Bird, et al. aimed to describe the real-world effecti...

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 by...
Upadacitinib treatment results in statistically significant and clinically meaningful improvements in health-related quality of life.Strand, et al. evaluated the effect of upadacitinib monotherapy versus methotrexate (MTX) on patient-reported outcomes (PRO) in MTX-naïve and MTX-inadequate responder patients with moderately-to-severely active RA. Their research from the SELECT-EARLY and SELECT-MONOTHERAPY randomised controlled trials found that upadacitinib monotherapy resulted in clinically mean...

The combination of JAK inhibitors with MTX is not associated with an increased risk of malignancy when compared to MTX alone. Although long-term studies are needed to confirm this conclusion from short-term studies. Although it is now known that patients with RA are predisposed to an increased risk of malignancy, especially malignant lymphomas, lung cancers and non-melanoma skin cancer, it remains unclear whether the combination therapy is associated with a higher risk.To this end, Solipuram, et...
Results from the COVID-19 Global Rheumatology Alliance physician registry show that people with RA using rituximab or JAKi, at COVID-19 onset, are more likely to experience poor COVID-19 outcomes, ranging from hospitalisation to death, compared with use of TNFi.The ongoing COVID-19 pandemic has had a significant impact on people with RA, many of whom are treated with b/tsDMARDs. To help address some of the knowledge gaps around the influence of b/tsDMARDs on COVID-19 outcomes, Sparks, et al. ana...
The influence of inflammation on patient global assessment (PGA) improvements differs between baricitinib and tocilizumab differs. Adequate PGA improvement remains one of the unmet needs in current RA treatment.Asai, et al. compared the effects of baricitinib and tocilizumab on disease activity in patients with RA while investigating the influence of inflammation on PGA improvement.Using data from a multicentre registry, 48 propensity-matched pairs of patients, who had been observed for longer t...
