MedicalResearch: What are the main findings of the study?
Dr. Wilkinson: ORAL Start showed that XELJANZ (tofacitinib citrate) 5 and 10 mg twice daily (BID), taken by itself without methotrexate (MX), inhibited the progression of structural damage and reduced the signs and symptoms of rheumatoid arthritis (RA), and was statistically significantly superior to methotrexate on these measures at Month 6 (primary endpoint) and at all measured time points up to 24 months in patients with rheumatoid arthritis who had not previously received methotrexate or therapeutic doses of methotrexate. XELJANZ is not indicated in patients who had not previously received methotrexate.
- Both doses of XELJANZ met the study’s co-primary efficacy endpoints of mean change from baseline in van der Heijde modified Total Sharp Score (mtss) [0.18 and 0.04 (both P<0.001) for tofacitinib 5 and 10 mg BID, respectively, versus 0.84 for MTX], and ACR70 response rates [25.5% and 37.7% for tofacitinib 5 and 10 mg BID (both P<0.001) versus 12.0% for MTX], at Month 6.
- These results were sustained at all measured time points up to 24 months.
