OBJECTIVE: To evaluate the interleukin-1 inhibitor rilonacept (Interleukin-1 Trap) for prevention of gout flares occurring in the first few months following initiation of urate-lowering therapy. METHODS: In this double-blind study, adult patients with hyperuricemia and gout were randomized to receive rilonacept administered subcutaneously once per week (loading dose 320 mg followed by 160 mg weekly) or placebo, and started on allopurinol (300 mg/day, titrated to serum urate <6 mg/dl). At study visits, physical and laboratory assessments were performed and information on any adverse events was ascertained. RESULTS: Baseline characteristics were similar between the rilonacept and placebo groups (n = 41 and n = 42, respectively). The mean number of gout flares per patient through week 12 (primary efficacy end point) was markedly lower in the rilonacept group than in the placebo group (0.15 [6 flares] versus 0.79 [33 flares]; P = 0.0011). Fewer flares were observed with rilonacept as early as 4 weeks after initiation of treatment (P = 0.007). The proportion of patients experiencing a flare during the 12 weeks was lower in the rilonacept group than in the placebo group (14.6% versus 45.2%; P = 0.0037). No rebound in the flare rate was observed for 6 weeks after discontinuation of rilonacept or placebo at week 16. Adverse events were similar between groups, and no deaths or serious infectious adverse events were reported; the most common adverse events were infections (14.6% and 26.2% of rilonacept- and placebo-treated patients, respectively) and musculoskeletal disorders (14.6% and 21.4%, respectively). A higher percentage of rilonacept-treated patients (98%) compared with placebo-treated patients (79%) completed the primary 12-week evaluation period (P = 0.015). CONCLUSION: The current findings indicate that rilonacept significantly reduces the frequency of gout flares during the initial period of treatment with urate-lowering therapy, with a favorable safety profile.
