| E.2 Objective of the trial | 
| E.2.1 | Main objective of the trial | 
| The primary objective of the randomized treatment epoch and for the overall study is to demonstrate that subcutaneous canakinumab administered every 4 weeks is superior to placebo in achieving a clinically meaningful reduction of disease activity defined as resolution of the index flare at Day 15 and no new disease flares over 16 weeks of treatment.
 
 
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| • To evaluate the percentage of patients who achieve a Physician Global Assessment of Disease Activity (PGA) <2 (“minimal” or “none”) at Week 16 • To evaluate the percentage of patients with the serologic remission at Week 16 (defined as C-reactive protein [CRP] <10 mg/L)
 • To evaluate the percentage of patients with normalized Serum Amyloid A (SAA) level at Week 16 (defined as SAA <10 mg/L)
 • To evaluate the percentage of canakinumab responders in Epoch 2 who maintain a clinically meaningful response (absence of new flares) when switched to canakinumab every 8 weeks compared to placebo (Epoch 3)
 • To evaluate the long-term safety and tolerability and immunogenicity of canakinumab
 • To evaluate the pharmacokinetics/ pharmacodynamics of canakinumab
 |  | 
| E.2.3 | Trial contains a sub-study | No | 
| E.3 | Principal inclusion criteria |
