Gouty arthritis is a painful inflammatory disease with a significant impact on patients' HRQoL. In gouty arthritis, the inflammatory response is initiated by interleukin-1b (IL-1b) release, due to activation of the NALP3 inflammasome by MSU crystals. Canakinumab, a fully human anti-IL-1b antibody has a long half-life and has been shown to control inflammation in gouty arthritis. This study evaluated changes in HRQoL in gouty arthritis patients following treatment with canakinumab or triamcinolone acetonide (TA).


This was an 8-week, dose-ranging, multi-center, active controlled, single-blind study. Patients (>=18 to <=80 years) experiencing an acute gouty arthritis flare, refractory to or contraindicated to NSAlDs and/or colchicine, were randomized to canakinumab 10, 25, 50, 90, 150 mg sc or TA 40 mg im. HRQoL was assessed as an exploratory endpoint at baseline and different pre-specified time-points using patient reported outcomes evaluating general mental and physical component summary scores and subscale scores of SF-36® (acute version 2) and functional disability (HAQ-DI©). We report HRQoL results for canakinumab 150 mg, the dose that was selected for the Phase III studies.


Baseline assessments showed a major impact on the HRQoL during acute gouty arthritis. Compared to TA, canakinumab 150 mg showed greater improvements in SF-36® physical and mental component summary and subscale scores at 7 days post-dose.

In the canakinumab 150 mg group, the most severe impairment at baseline was reported for physical functioning and bodily pain; levels of 41.5 and 36.0, respectively, which improved within 7 days to 80.0 and 72.2 (mean increases of 39.0 and 35.6) approaching levels of the general US population (84.2 and 75.2). 8 weeks post-dose patients reached levels of 86.1 and 86.6 (mean increases of 44.6 and 50.6 for physical functioning and bodily pain, respectively) and these were higher than levels seen in the general US population. This was in contrast to patients treated with TA, who showed less improvement within 7 days (mean increases of 23.3 and 21.3 for physical function and bodily pain, respectively). None of the scores reached levels of the general US population 8 weeks post-dose. Functional disability scores, as measured by the HAQ-DI© decreased in both treatment groups (Table).

All canakinumab doses showed a rapid improvement in physical and mental well-being of gouty arthritis patients based on SF-36® scores, in particular the 150 mg dose. In contrast to the TA group, patients treated with canakinumab showed improvement within 7 days in physical function and bodily pain approaching levels of the general population. The 150 mg dose of canakinumab was selected for further development in Phase III studies.
