简要总结
This study is to determine whether canakinumab is able to induce and maintain a clinically meaningful reduction of disease activity in participants with Hereditary Periodic Fevers (HPF) compared to placebo.
详细描述
This study consists of 3 randomized cohorts (one per condition of colchicine resistant/intolerant Familial Mediterranean Fever (crFMF), Hyper Immunoglobulin D Syndrome (also known as mevalonate kinase deficiency (HIDS/MKD), and Tumor Necrosis Factor Receptor Associated Periodic Syndrome (TRAPS), and 4 study epochs:
-
Epoch 1: a screening epoch to assess participant's eligibility;
-
Epoch 2: a randomized treatment epoch of 16 weeks where participants are randomized to canakinumab 150 mg every 4 weeks (q4w) or to placebo to obtain efficacy and safety data in a double-blind placebo controlled parallel-arm setting. This epoch contained 2 possible escape options :
-
early blinded escape option for non responders from Day 8 to Day 28 with here an add-on dose of 150mg canakinumab followed by blinded uptitration at the next scheduled visit (Day 29)
-
late unblinded escape option for non responders from Day 29 to Day 112; with open-label uptitration
-
Epoch 3: a randomized withdrawal epoch of 24 weeks where canakinumab responders from the randomized treatment epoch were re-randomized to canakinumab 150mg q8w or placebo to assess the potential for canakinumab to maintain clinical efficacy at a reduced dosing frequency;
-
Epoch 4: an open-label treatment epoch of 72 weeks to collect long-term

研究组 & 干预措施
crFMF: 150 mg
During Epoch 2, participants received canakinumab 150mg (or 2mg/kg for participants weighing <= 40kg) q4w for 16 weeks. If participants were eligible for blinded escape, they received a single add-on dose of canakinumab (150 mg or 2mg/kg for participants weighing <= 40kg) between day 8 and day 28, and then received blinded uptitration to canakinumab 300 mg q4w from day 29 through day 112. If patients on the highest allowed canakinumab dose of 300 mg (or 4 mg/kg for patients weighing ≤ 40 kg) q4w and re-flared (PGA ≥ 2 and CRP ≥ 30 mg/L) were not eligible for further up-titration.
干预措施: Canakinumab (Drug)
crCMF: placebo
During epoch 2, participants received matching placebo to canakinumab 150 mg Participants who required blinded escape,they received a single add-on dose of canakinumab (150 mg or 2mg/kg for participants weighing <= 40kg) between day 8 and day 28, and then received blinded one dose of placebo and one dose of canakinumab q4w from day 29 through day 112. If flare or re-flare still occurred after receipt of canakinumab.
150mg, participants were uptitrated to open-label canakinumab 300 mg.
干预措施: Placebo (Drug)
HIDS/MKD: 150 mg
During Epoch 2, participants received canakinumab 150mg (or 2mg/kg for participants weighing <= 40kg) q4w for 16 weeks. If participants were eligible for blinded escape, they received a single add-on dose of canakinumab (150 mg or 2mg/kg for participants weighing <= 40kg) between day 8 and day 28, and then received blinded uptitration to canakinumab 300 mg q4w from day 29 through day 112. If patients on the highest allowed canakinumab dose of 300 mg (or 4 mg/kg for patients weighing ≤ 40 kg) q4w and re-flared (PGA ≥ 2 and CRP ≥ 30 mg/L) were not eligible for further up-titration.

结局指标
主要结局
Percentage of Participants With Resolution of Initial Flare and Absence of New Flares up to the End of the Randomized Treatment Epoch (16 Weeks)
时间窗: 16 weeks
Resolution of the initial disease flare is defined as: Physician's Global Assessment of Disease activity (PGA) \<2 and C-reactive protein (CRP) within normal range (\<= 10 mg/L) or reduction by at least 70% from baseline. The PGA was evaluated by the investigator based on a 5-point scale: 0 = None (no) disease associated with clinical signs and symptoms; 1 = minimal disease associated signs and symptoms; 2 = mild disease associated signs and symptoms; 3 = moderate disease associated signs and symptoms; and 5 = severe disease associated signs and symptoms.
次要结局
- Percentage of Participants With the Serologic Remission(16 weeks)
- Percentage of Participants With Normalized Serum Amyloid A (SAA) Level(16 weeks)
- Percentage of Participants Who Achieve Physician's Global Assessment (PGA) < 2(16 weeks)
- Percentage of Participants of Canakinumab Responders From Epoch 2 Who Maintained a Clinically Meaningful Response (Absence of New Flares) (40 Weeks)(40 weeks)
