  Description
Canakinumab In Part I participants received open label 4 mg/kg canakinumab subcutaneous injection every 4 weeks for up to 32 weeks. For the first 8 weeks Part Ia (4 weeks) and Ib (4 weeks) patients maintained a stable oral steroid dose (prednisone or equivalent) followed by Ic an up to 20 week steroid tapering period and then Id a 4 week stable steroid dose period. Participants were then randomized to receive either 4 mg/kg canakinumab subcutaneous injection or Placebo comparator in Part II and remained on the stable oral steroid dose for 24 weeks. At 24 weeks in Part II participants with a >0.2 mg/kg and ≤ 0.5 mg/kg and no flare could restart steroid tapering. If the steroid dose was ≤ 0.2 mg/kg participants continued to maintain their current dose for the remainder of Part II.
Placebo Participants in Part II received placebo matching canakinumab subcutaneous injection every 4 weeks. At 24 weeks in Part II participants with a >0.2 mg/kg and ≤0.5 mg/kg and no flare could restart steroid tapering. If the steroid dose was ≤0.2 mg/kg participants continued to maintain their current dose for the remainder of Part II.
