Abstract

Abstract : Background: Tofacitinib is an oral Janus kinase inhibitor under investigation for psoriatic arthritis (PsA). Interim data (database not locked) from ≤24 months' participation (3 years' total treatment duration) for patients (pts) with active PsA in an ongoing, open-label, long-term extension study (LTE; NCT01976364 OPAL Balance) is reported. Objectives: To evaluate the safety, tolerability and efficacy of tofacitinib in pts with active PsA. Methods: Eligible pts from 2 pivotal Phase 3 tofacitinib PsA studies (NCT01877668 OPAL Broaden, NCT01882439 OPAL Beyond) could enter a 3-year LTE ≤3 months after completing the qualifying study or discontinuing for non study-drug-related reasons. Pts were to receive tofacitinib 5 mg twice daily (BID) for 1 month, after which an increase to 10 mg BID or reduction back to 5 mg BID was permitted at any time for efficacy or safety reasons. Concomitant treatment with a single conventional synthetic disease-modifying antirheumatic drug (csDMARD) was allowed but not required. Primary endpoints were incidence and severity of adverse events (AEs) and change from baseline in laboratory values. Efficacy was a secondary endpoint. Results: 680/685 enrolled pts were treated. 608 (89.4%) remained at data cut-off. Mean (range) duration of tofacitinib exposure in this LTE was 206 (3–741) days. 661 (97.2%) pts took a csDMARD on Day 1, and 73 (11.0%) later discontinued csDMARD. To Month 24, 860 AEs were reported in 367 (54.0%) pts, 41 (6.0%) pts had serious AEs and 24 (3.5%) pts discontinued due to AEs. Special interest AEs included 6 serious infections (0.9%), 10 herpes zoster events (1.5%) including 1 serious event, 2 major adverse cardiovascular events (0.3%) and 2 malignancies (0.3%). There were 3 deaths (not attributed to treatment, as assessed by the investigator) due to metastatic pancreatic carcinoma, acute cardiac failure and pulmonary embolism. No GI perforation, inflammatory bowel disease or uveitis cases were reported. One AE of latent TB was reported. One pt met discontinuation criteria for laboratory values due to increased serum creatinine >50% and >0.5 mg/dL over the average of screening and baseline creatinine. Small mean decreases in absolute lymphocyte and neutrophil counts, and small mean increases in serum lipid markers, were observed; 18 (2.6%) pts started new lipid-lowering medication during the LTE (80 [11.8%] pts were on lipid-lowering drug at baseline). Efficacy was maintained in the LTE (Table 1 ). Conclusions: Over 24 months in the LTE, the safety profile of tofacitinib in pts with active PsA was generally similar to that of the pivotal Phase 3 studies. No new safety signals were identified. Efficacy was maintained over time. Acknowledgements: To be presented at AAD 2017 and reproduced with permission. This study was sponsored by Pfizer Inc.
