This study was one of two 24-week, phase 2b studies undertaken to characterise the efficacy and safety dose-response profile of the oral Janus kinase (JAK) inhibitor tofacitinib. Six doses of tofacitinib (20 mg daily and 1, 3, 5, 10 and 15 mg twice daily) and placebo were compared as add-on therapy in adults with active RA despite methotrexate (MTX) therapy. At week 12, ACR 20 response rates were significantly higher with all tofacitinib doses than with placebo (tofacitinib 45.7–58.1%; 33% place...

This is the first phase 3 study to be published for the oral Janus kinase (JAK) inhibitor tofacitinib. This study investigated tofacitinib as a monotherapy in adults with active rheumatoid arthritis who previously failed to respond to disease modifying anti-rheumatic drugs (DMARDs). The study demonstrated that tofacitinib, compared to placebo, was more likely to be associated with reductions in the signs and symptoms of rheumatoid arthritis and improvement in physical function. 59.8% of patients...

The ORAL Standard trial is one of six studies conducted as part of the phase 3 research programme for the oral Janus kinase (JAK) inhibitor tofacitinib. This 12-month, phase 3 study compared the efficacy of tofacitinib with the TNF inhibitor adalimumab or placebo. Patients with active RA despite background methotrexate (MTX) were randomised to 5 or 10 mg tofacitinib twice daily, 40 mg adalimumab fortnightly, or placebo, which was switched to tofacitinib at month 3 in non-responders and month 6 f...

The ORAL Step trial is one of six studies conducted as part of the phase 3 research programme for the oral Janus kinase (JAK) inhibitor tofacitinib. This 6-month, double-blind, parallel-group phase 3 study investigated the efficacy and safety of tofacitinib in adults with moderate to severe rheumatoid arthritis (RA) with an inadequate response to tumour necrosis factor (TNF) inhibitors. Patients were randomised to 5 or 10 mg tofacitinib twice daily or placebo, which was switched to tofacitinib a...
