title: Canakinumab: in patients with cryopyrin-associated periodic syndromes.
abstract: Canakinumab is a recombinant, fully human, monoclonal, anti-human interleukin-1β (IL-1β) antibody that binds with high affinity and specificity to human IL-1β, preventing its interaction with IL-1 receptors. Canakinumab (150 mg in patients weighing >40 kg or 2 mg/kg in those weighing 15-40 kg) administered once every 8 weeks as a single dose via subcutaneous injection provided a rapid and sustained response in patients with cryopyrin-associated periodic syndromes (CAPS). During the initial 8-week phase of a three-part, phase III trial, a complete response to a single dose of canakinumab occurred in 97% of the 35 patients with CAPS, with 71% of responses occurring within 8 days. After 8 weeks, 31 responders entered a 24-week, randomized, double-blind, withdrawal phase; there was a significant between-group difference in this phase in that none of the canakinumab recipients relapsed compared with 81% of placebo recipients. All patients from the second phase of the trial entered a third, 16-week phase of open-label treatment with canakinumab once every 8 weeks; clinical and biochemical remission was maintained in 28 of 29 patients who completed the trial. In a 2-year, open-label, phase III trial, subcutaneous canakinumab once every 8 weeks provided sustained disease control in the majority of patients with CAPS. Canakinumab was generally well tolerated in all trials, with the predominant adverse events being mild to moderate infections that were responsive to standard treatment.
