E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Part II: to demonstrate that the time to flare in Part II is higher with canakinumab than with placebo. Part I: to assess if canakinumab allows tapering of steroids as per protocol in at least 25% of the patients. |
|
E.2.2 | Secondary objectives of the trial |
Part II: • To evaluate the maintenance of efficacy (length of time that patients continuously maintain or improve their adapted ACR Pediatric 30/ 50/ 70/ 90/ 100 criteria reached at entry into Part II) of canakinumab as compared to placebo Part I: • To evaluate number of patients who have reached a steroid dose ≤ 0.2 mg/kg at end of Part Ic • To evaluate the level of steroid tapering achieved at the end of Part Ic • To evaluate the efficacy (percentage of patients who meet the adapted ACR Pediatric 30/ 50/ 70/ 90/ 100 criteria) of canakinumab in Part I • To evaluate the efficacy of canakinumab to show clinical signs of response (percentage of patients who have body temperature ≤ 38°C) at Day 3 in Part Ia • To evaluate time to adapted ACR Pediatric 50 criteria and no fever and normal C-Reactive Protein (CRP <10 mg/L) during Part I see other objectives in protocol pages 24-25 |

With underlying metabolic, renal, hepatic, infectious or gastrointestinal conditions which in the opinion of the investigator immunocompromises the patient and/ or places the patient at unacceptable risk for participation in an immunomodulatory therapy. In particular, clinical evidence or history of multiple sclerosis or other demyelinating diseases, or Felty’s syndrome. 8. With significant medical conditions, which in the opinion of the Investigator will exclude the patient from the study (can be discussed on a case by case basis with Novartis) 9.
