Patient-reported outcomes (PROs) vastly improved in the first 24 weeks post-initiation of tocilizumab (TCZ) therapies compared to methotrexate (MTX) monotherapy in the U-Act-Early trial.U-Act-Early was a two-year, treat-to-target study that compared the safety and efficacy of TCZ and MTX treatment strategies in DMARD-naïve patients with early RA. Sustained remission was classed as more effective in patients given TCZ monotherapy or combination therapy with MTX compared to MTX alone. TCZ therapie...

In this post hoc analysis, six Phase 3 studies were used to analyse the effect of glucocorticoids (GC) on the efficacy of tofacitinib (TOF) in patients with RA. Concomitant use of GC did not affect the clinical or radiographic outcomes of patients treated with TOF. Data from all six clinical trials were evaluated, with four studies (ORAL Scan, ORAL Standard, ORAL Sync and ORAL Step) being pooled for analysis. In these studies, MTX was used as a comparison and patients were required to maintain a...

JAK Inhibition as a Therapeutic Strategy for Immune and Inflammatory Diseases

Nat Rev Drug Discov 2017;16:843–62 DOI: 10.1038/nrd.2017.201

Janus kinases (JAKs) are essential mediators of downstream signaling pathways in many inflammatory and autoimmune diseases. This review summarizes current clinical data on first- and second-generation JAK inhibitors (jakinibs) and discusses their use for the treatment of immune and inflammatory conditions.First generation jakinibs such as tofacitinib, baricitinib, and ruxolitinib, non-selectively inhibit JAK-dependent pro-inflammatory cytokines, which are major contributors to immunopathology. T...

Successful Treatment of Arthritis Induced by Checkpoint Inhibitors with Tocilizumab: a Case Series

Ann Rheum Dis 2017;76:2061-64. doi: 10.1136/annrheumdis-2017-211560

This case series evaluated the use of tocilizumab (TCZ) as an effective treatment for patients who develop arthritis as an adverse event (AE) of immune checkpoint inhibitor (ICI) cancer treatment. Results suggested that TCZ was an effective treatment, as it reduced the arthritis disease progression.ICIs have been defined as a revolutionary treatment for metastatic melanomas; however, a common AE is the development of polyarthritis. Current arthritis treatments reduce the efficiency of ICI therap...

The results of this analysis of patients with herpes zoster (HZ) within the global tofacitinib (TOF) RA programme suggest that there is likely to be a greater HZ risk in patients receiving TOF and glucocorticoids compared with patients receiving TOF monotherapy.The global TOF RA development programme comprised 2 Phase 1, 9 Phase 2, 6 Phase 3 and 2 long-term extension studies. These studies included 6192 patients; data were reviewed to identify cases of HZ. Crude incidence rates of number of pati...

Tofacitinib or Adalimumab versus Placebo for Psoriatic Arthritis

N Engl J Med 2017; 377:1537-50. DOI: 10.1056/NEJMoa1615975

In the Phase 3 OPAL Broaden trial of patients with active psoriatic arthritis (PsA) with inadequate response to ≥1 csDMARD, superior efficacy was observed in patients treated with tofacitinib (TOF) compared with those given placebo. Patients were randomised to: 5 mg TOF BID, 10 mg TOF BID, 40 mg adalimumab administered subcutaneously q2W, or placebo with a switch to 5 mg TOF at Month 3. Adalimumab was used as an active control in the study. A variety of primary and secondary endpoints were used ...
The study data presented that tofacitinib (TOF) improves efficacy response rates in patients with severe psoriatic arthritis (PsA) who have an inadequate response to TNF inhibitors.The Phase 3 Oral Psoriatic Arthritis Trial (OPAL) Beyond study evaluated patients with active PsA who had inadequate responses to more than one TNFi. Patients were randomised 2:2:1:1 to 5 mg TOF BID or 10 mg TOF BID for 6 months; or PBO, with a switch to 5 mg TOF BID or to 10 mg BID at 3 months.Primary endpoints were ...

Safety and Efficacy of Baricitinib in Elderly Patients with Rheumatoid Arthritis

RMD Open. 2017; 3(2): e000546. doi: 10.1136/rmdopen-2017-000546

In this post hoc analysis of pooled data from two randomised controlled trials, RA-BUILD and RA-BEAM, age was shown not to be a contraindication for use of baricitinib. Patients in RA-BUILD were csDMARD-inadequate responder(IR) patients who received an oral placebo or 2 mg or 4 mg baricitinib once daily. Patients in RA-BEAM were MTX-IR patients and received an oral placebo, 4 mg baricitinib once daily or subcutaneous adalimumab every 2 weeks. Efficacy and safety of baricitinib in elderly patient...

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...
