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...

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...

This randomised, placebo-controlled, multicentre phase 2 study evaluated the efficacy and safety of atorvastatin versus placebo in modifying lipids in 111 patients with active rheumatoid arthritis (RA) receiving tofacitinib. All patients took tofacitinib 10 mg twice daily for 12 weeks, and after the first 6 weeks patients were randomised 1:1 to receive either atorvastatin 10 mg once daily (n=50) or matched placebo (n=48) in a double-blind phase for a further 6 weeks. Tofacitinib-induced elevatio...
