Patients with RA who started treatment with tofacitinib 2–3 weeks after being vaccinated against herpes zoster had similar varicella zoster virus (VZV)-specific humoral and cell-mediated responses to the live vaccine compared to patients who received placebo.In this Phase 2 study, humoral and cell-mediated immune responses were evaluated before receipt of live zoster vaccine (LZV) and at 2, 6 and 14 weeks after vaccination, having been randomised to tofacitinib 5 mg BID or placebo, 2–3 weeks aft...
Patients who were treated with tofacitinib in the RA clinical development programme were more likely to develop herpes zoster than were those who received placebo.Cases of herpes zoster reported by investigators in the Phase 2, Phase 3 and long-term extension studies of tofacitinib were evaluated. Herpes zoster was noted in 5% of tofacitinib-treated patients; only 7% of these cases were serious, no patients with herpes zoster died and only 10% permanently discontinued tofacitinib treatment.The o...
This open-label extension (OLE) of a Phase 2b randomised controlled trial (RCT) found that safety data collected over 2 years of treatment were generally consistent with previous findings for baricitinib in RA.In the RCT, baricitinib demonstrated significant improvement in disease activity compared with placebo and an acceptable safety profile in patients with RA and an inadequate response to MTX. Patients who completed the 24-week double-blind period of the study were eligible for the OLE. Rate...

Because non-melanoma skin cancer (NMSC) is one of the most common malignancies associated with RA immunomodulatory therapies, this analysis looked to determine the rate of NMSC incidence per 100 patient-years in patients with RA receiving TOF in the clinical trial programme. The Phase 1, 2, and 3 IRs (combined) for both TOF 5- and 10 mg were low and comparable to those of adalimumab, MTX and placebo, IRs remained stable over time. TOF doses used in the 2 Phase 1; 8 Phase 2; and 6 Phase 3 studies...

This analysis of exposure to tofacitinib, an oral JAKi for the treatment of RA, for up to 8.5 years allowed estimation of safety events with improved precision versus previous tofacitinib reports. Adverse events were generally stable over time; no new safety signals were observed compared with previous tofacitinib reports.Data were collated into an integrated safety summary of tofacitinib in adult patients with active RA, and included data spanning the tofacitinib clinical programme: from 2 Pha...
To date, the comparative efficacy of tocilizumab and TNFi for patients with RA has only been investigated in a single head-to-head trial and network meta-analyses. This study, ACT-iON, is the first prospective, large-scale, global, multicentre, comparative effectiveness study comparing initiation of intravenous tocilizumab with initiation of a TNFi in patients with RA as the first-line biologic treatment after inadequate response to csDMARDs. Patients were observed in a real-world, clinical pra...
In this first head-to-head non-inferiority trial assessing a JAKi ± MTX directly compared with a TNFi + MTX in patients with RA, tofacitinib (TOF) + MTX showed non-inferiority to adalimumab (ADA) + MTX. Non-inferiority was not shown for TOF monotherapy versus TOF + MTX, or versus ADA + MTX.In this 52-week study, MTX-inadequate responder (IR) patients were randomised 1:1:1 to receive TOF 5 mg BID monotherapy, TOF 5 mg BID + MTX or ADA 40 mg every other week + MTX. The primary endpoint, ACR50 resp...
In two 4-week exploratory Phase 2a trials in MTX-inadequate responder (IR) patients with RA, the highly selective JAK1 inhibitor filgotinib met the primary endpoint of ACR20 at Week 4, showing greater response than placebo.Study 1, a proof-of-concept study, included 127 patients randomised to placebo, filgotinib 100 mg BID or filgotinib 200 mg QD. Study 2, was a dose-ranging study and included 91 patients randomised to placebo, filgotinib 30 mg QD, filgotinib 75 mg QD, filgotinib 150 mg QD or fi...

Burmester et al. present data showing that 52-week efficacy and safety of intravenous tocilizumab plus methotrexate, or tocilizumab monotherapy are maintained through to Week 104 in patients with early rheumatoid arthritis. Patients were assigned to four treatment groups: 4 mg/kg TCZ + MTX, 8 mg/kg TCZ + MTX, 8 mg/kg TCZ + placebo or placebo + MTX. Patients not achieving DAS28 ≤3.2 at Week 52 and who were not receiving 8 mg/kg TCZ were rescued to 8 mg/kg TCZ + MTX. Of the 1162 randomly assigned ...

This review discusses the current understanding of the safety of JAK inhibitors, including providing an overview of the changes in laboratory parameters, infection and malignancy risks associated with each JAK inhibitor compound.The review discusses the adverse event profiles and cellular changes characteristically seen with each JAK inhibitor, as well as the overlap or differences between the various compounds. The relative specificities for different JAKs between each compound do not always p...
