Session Type: ACR Poster Session B
Session Time: 9:00AM-11:00AM
Background/Purpose: Rheumatoid arthritis (RA) has a high patient (pt) burden with significant impact on health-related quality of life. We report the effect of treatment with olokizumab (OKZ), an interleukin-6 (IL-6)-targeting monoclonal antibody, on pt-reported outcomes (PROs) in both Western and Asian pts with moderate to severe RA who have previously failed anti-TNF therapy.
Methods: Data are reported from two multicenter, double-blind RCTs, RA0056 (NCT01242488) and RA0083 (NCT01463059), and their corresponding open-label extension (OLE) studies, RA0057 (NCT01296711) and RA0089 (NCT01533714). In the RCTs, pts with RA receiving MTX who had previously failed anti-TNF therapy were recruited from Belgium, the US and the UK (RA0056),1 and Japan, Korea and Taiwan (RA0083).2 Pts received placebo (PBO), subcutaneous (sc) OKZ 60/120/240 mg every 2 weeks (wks; Q2W) or 4 wks (Q4W) (240 mg Q2W in RA0056 only), or (in RA0056 only) intravenous tocilizumab (TCZ) 8 mg/kg Q4W. Completers were eligible for the OLEs, in which all pts received sc OKZ 120 mg Q2W + MTX (RA0057: 12.5–25.0 mg/wk with dose reductions permitted after Wk 12; RA0089: 6.0–16.0 mg/wk in Japan, 7.5–20.0 mg/wk in Korea and Taiwan). Pts with ongoing serious adverse events were excluded from the OLEs. Clinical efficacy and safety data have been reported previously.1,2 PROs assessed included health assessment questionnaire-disability index (HAQ-DI), pt’s global assessment of disease activity (PtGADA), pt’s assessment of arthritis pain (PtAAP), Bristol Rheumatoid Arthritis Fatigue-Multi-Dimensional Questionnaire (BRAF-MDQ) and EuroQol 5-Dimensions Questionnaire (EQ-5D). Data are reported for the OL full analysis set (all pts who received ≥1 dose of OKZ with ≥1 efficacy measurement in the OLE). Observed data are reported for Wk 12 of the RCTs and the last time point at which ≥50% of pts reported data in the OLEs; Wk 48 in RA0057 and Wk 40 in RA0089.
Results: 198 pts completed RA0056; 190 (114 OKZ, 40 PBO, 36 TCZ) enrolled in RA0057. 105 pts completed RA0083; 103 (79 OKZ, 24 PBO) enrolled in RA0089. At Wk 12 of the RCTs, both Western (Table A) and Asian (Table B) OKZ-treated pts reported greater improvements in PROs compared to PBO-treated pts, similar to TCZ pts. As expected, PBO-treated pts reported rapid improvements in PROs following switch to OKZ. These changes were maintained to Wk 40/48 of the OLE both in pts receiving OKZ throughout (OKZ→OKZ) and in TCZ-pts switching to OKZ at OLE entry (TCZ→OKZ). Improvements were comparable in magnitude in Western and Asian patients.
Conclusion: OKZ treatment of both Western and Asian pts with moderate to severe RA resulted in sustained improvements across a range of PROs, both in the RCT and OLE, with similar levels of improvement seen in both populations. Changes were maintained to the last time point examined: Wk 40 in Asian pts and Wk 48 in Western pts. References: 1. Genovese M. Ann Rheum Dis 2014;73(9):1607–15; 2. Takeuchi T.
