Pfizer XELJANZ Phase 3 findings support safety, efficacy

Pfizer announced the publication of two-year results from the ORAL Start study in the June 19 issue of The New England Journal of Medicine. ORAL Start is a 24-month Phase 3 study in patients with moderately to severely active rheumatoid arthritis who had not previously received methotrexate. The study showed that XELJANZ 5 mg and 10 mg twice daily, as monotherapy, inhibited the progression of structural damage and reduced the signs and symptoms of rheumatoid arthritis, and was statistically significantly superior to methotrexate on these measures at Month 6 and at all measured time points up to 24 months. XELJANZ is not indicated in patients who had not previously received methotrexate. The safety profile of XELJANZ in the ORAL Start study was consistent with that seen previously in the clinical development program. In the United States, XELJANZ 5 mg tablets are indicated for the treatment of adults with moderately to severely active rheumatoid arthritis who have had an inadequate response or intolerance to methotrexate. XELJANZ may be used alone or in combination with methotrexate or other non-biologic, disease-modifying antirheumatic drugs. Use of XELJANZ in combination with biologic DMARDs or potent immunosuppressants, such as azathioprine and cyclosporine, is not recommended. The recommended dose is a 5 mg pill taken twice daily.
