The JAK inhibitor tofacitinib for active rheumatoid arthritis: results from phase III trials

International Journal of Clinical Rheumatology June 2013; 8(3):311–13

The tofacitinib ORAL research program involves six phase 3 trials (Standard, Solo, Step, Scan, Sync and Start) to assess the safety and efficacy of tofacitinib 5 and 10 mg twice daily as monotherapy, or with either background MTX or traditional DMARD therapy. This report by Salgado et al. provides an overall analysis of the each of the study designs and the clinical results to date. The results show that tofacitinib effectively controlled the signs and symptoms of RA across a range of patient po...

This preclinical characterisation study examined the efficacy and tolerability of the small molecule INCB028050 (now known as baricitinib), an orally bioavailable, selective Janus kinase (JAK) 1/JAK2 inhibitor, in rodent models of arthritis. The decision to investigate its effects of INCB028050 followed positive evidence for the related compound ruxolitinib, the JAK inhibitor tofacitinib and the IL-6 inhibitor tocilizumab in rheumatoid arthritis (RA). In this preclinical study, INCB028050 was sh...
The ORAL Scan trial is one of six studies conducted as part of the phase 3 research programme for the oral Janus kinase (JAK) inhibitor tofacitinib. This is the 12-month interim results published for the ORAL Scan study, a 24-month, phase 3 study that compared the effects of tofacitinib and placebo on structural preservation in patients with active RA despite methotrexate therapy. Patients were randomised to 5 or 10 mg tofacitinib twice daily or placebo, which was switched to 5 or 10 mg tofaciti...
