Abstract

Abstract : Background: Tofacitinib is an oral Janus kinase inhibitor for the treatment of rheumatoid arthritis that is being investigated for psoriasis. Objectives: To report pooled trial safety data in patients with psoriasis to expand knowledge around the safety profile of tofacitinib in inflammatory diseases. Methods: The 1-year randomised controlled trials (RCT) group included patients with psoriasis who received ≥1 dose of tofacitinib 5 or 10 mg BID in three 1-year Phase 3 RCTs. The integrated safety group included patients with psoriasis who received ≥1 dose of tofacitinib in four Phase 3 studies (5 or 10 mg BID) or a long-term extension (LTE) study. In the LTE study, patients entered following one Phase 2 study or the Phase 3 studies and received 10 mg BID (for 3 months), then 5 or 10 mg BID (ongoing, database not locked, data cut-off April 4, 2014). Incidence rates (IR; patients with events/100 patient-years) were calculated for the 1-year RCT and integrated safety groups. For the integrated safety group, data were pooled across doses. Results: In the 1-year RCT group, 2436 patients received tofacitinib (5 mg BID, n=1217; 10 mg BID, n=1219), with a median of 253 days of tofacitinib exposure (range: 1–431, first and third quartiles: 168, 364). In the integrated safety group, 3623 patients received tofacitinib, with a median of 527 days of tofacitinib exposure (range: 1–1344, first and third quartiles: 261, 766). Serious infection IRs were 1.37 and 2.42 respectively for 5 and 10 mg BID in the 1-year RCT group, and 1.68 in the integrated safety group. Herpes zoster IRs were 1.00 and 2.32 for 5 and 10 mg BID in the 1-year RCT group, and 2.55 in the integrated safety group. Malignancy (excluding non-melanoma skin cancer [NMSC]) IRs were 1.12 and 0.81 for 5 and 10 mg BID in the 1-year RCT group, and 1.00 in the integrated safety group. NMSC IRs were 0.63 and 1.27 for 5 and 10 mg BID in the 1-year RCT group, and 0.74 in the integrated safety group. Major adverse cardiovascular event IRs were 0.50 and 0.23 for 5 and 10 mg BID in the 1-year RCT group, and 0.37 in the integrated safety group. In the 1-year RCT group, 95% confidence intervals for 10 vs 5 mg BID hazard ratios included 1 for each of these events. Conclusions: Serious infection, herpes zoster and NMSC IRs were numerically, but not statistically, higher with 10 vs 5 mg BID. IRs were similar in the RCT group and the integrated safety group, indicating that IRs are stable over time. Tofacitinib was well tolerated in patients with plaque psoriasis – including up to 44 months of exposure for some patients in the ongoing LTE study at data cut-off.
