Anakinra an effective option for gout flares, Study says

Patients unsuitable for NSAIDs and colchicine were enrolled in this multi‐center, randomized, double‐blind study lasting for up to 2 years (NCT03002974). The design was to show superiority of anakinra (100 or 200 mg/day for 5 days) over triamcinolone (40 mg single injection) for primary endpoint of changed patient‐assessed pain intensity from baseline to 24–72 hours in the most affected joint measured on visual analogue scale (0–100). Secondary outcomes included: safety, immunogenicity, and patient's and physician's global response assessments.

A total of 165 patients were randomized (110 to anakinra, 55 to triamcinolone) with a median age of 55 (range 25–83) years out of which 87% were men, mean disease duration was 8.7 years, and mean number of self‐reported flares during prior year was 4.5. In total, 301 flares were treated (214 anakinra; 87 triamcinolone).

The following results were observed-

a. Both anakinra doses and triamcinolone provided clinically meaningful reduction in patient‐assessed pain intensity in the 1st and subsequent flares.

b. For the 1st flare, the mean pain intensity decline from baseline to 24–72 hours for total anakinra and triamcinolone was ‐41.2 and ‐39.4, respectively (p=0.688).

c. Most secondary endpoints favored anakinra.

d. No unexpected safety findings were identified.

e. Presence of anti‐drug antibodies was not associated with adverse events or altered pain reduction.

Therefore, the authors concluded that "Anakinra was not superior to triamcinolone for the primary endpoint, but had comparable efficacy in pain reduction, and was favored for most secondary endpoints. Anakinra is an effective option for gout flares when conventional therapy is unsuitable."
