Methods: The study (NCT02059291) consists of 3 disease cohorts (crFMF, HIDS /MKD and TRAPS) and 4 study epochs: a screening epoch (E1) of up to 12 wks, a randomized treatment epoch (E2) of 16 wks, a randomized withdrawal epoch (E3) of 24 wks and an open-label treatment epoch (E4) of 72 wks. Pts (aged ≥2 years) with a flare during E1were randomized (1:1) in E2 to receive CAN or placebo (PBO). Primary objective was to demonstrate that CAN 150 mg (or 2 mg/kg for pts ≤40 kg) sc q4w is superior to PBO. Safety assessments included adverse events (AEs) and serious AEs(SAEs).
Results: Of 181 pts (crFMF, n=63; HIDS/MKD, n=72; TRAPS, n=46) randomized in E2, 6 discontinued the study (5 PBO; 1 CAN). In all 3 disease cohorts, the proportion of responders for the primary outcome at Wk 16 was significantly higher with CAN vs PBO. At Wk 16, a significantly higher proportion of pts achieved a physician’s global assessment (PGA) score <2, C-reactive protein (CRP) ≤10 mg/L and serum amyloid A (SAA) ≤10 mg/L in the CAN group vs PBO in all 3 cohorts. The most frequently affected system organ class across 3 cohorts was infections and infestations typically involving the upper respiratory tract. The incidence of SAEs was 8.6%, 4.7% and 11.8% in crFMF, TRAPS and HIDS/MKD cohorts, respectively.
Conclusion: These results demonstrated superior efficacy of canakinumab after a 16-week treatment period compared with placebo. The overall safety profile was not distinct from those reported in previous controlled studies.
