Patients 1–4 were initially treated with 10 mg/kg and 1 mg/kg i.v. and subsequently with fixed doses of 150 mg s.c. Patients 5–7 did not receive i.v. dosing but received fixed doses of 150 mg s.c. Because of difficulties being compliant with study visit requests, patient 6 withdrew consent after the sixth dose of 150 mg canakinumab s.c. The patient was subsequently treated with anakinra. n.a., not applicable.
After this cycle, patients were rolled over into the subsequent study, in which they were treated with a fixed dosing regimen of 150 mg s.c. every 8 wk.
