Canakinumab is a recombinant monoclonal fully human antibody against Interleukin-1β and currently the only drug approved for the treatment of CAPS in Europe. Current dose recommendations are 150mg (body weight >40kg) respectively 2mg/kg bodyweight (15 to 40kg) every 8 weeks but yield insufficient response in some individuals, especially in children and patients with severe phenotypes [1].


In this study we analyzed the response to daily practice (in contrast to trial condition) canakinumab treatment regimens in CAPS-patients with focus on age, mutation and clinical presentation and the necessity and effect of dose adjustment.


An observational national multicenter study was conducted. CAPS-Patients were included if they received at least two doses of canakinumab. Data included information regarding demographics, treatment, clinical disease activity and inflammatory markers (including SAA, CRP, S100, ESR, IL-6). Response to treatment was assessed using CAPS-disease activity scores, CRP and/or SAA levels.


A cohort of 68 patients with CAPS was analyzed. At the beginning of treatment 27 patients had been younger than 18 years with a median age of 25.4 years (range 22 months to 73 years). The most frequent mutations were R260W, A439V, E311K, V198M, Q703K and most patients showed MWS or FCAS/MWS phenotype (3 patients with NOMID, 4 with MWS/NOMID). The median treatment duration was 855 days (range: 28-1973 days). In 57% (39) of patients full response was sustained until next scheduled drug application (34% (23) partial remission). With standard treatment 31% (21) of patients achieved full response. In 44% (30) of all patients canakinumab dose and/or application interval was increased above the standard regimen (2/3 NOMID, 3/4 MWS/NOMID). Two serious adverse events were reported (severe infection, osteonecrosis), mild and moderate adverse events were mostly upper respiratory tract infections but almost no injection site reactions.


Most CAPS-Patients achieve full remission with canakinumab. However, almost 50% of patients, particularly children, require dose adjustment. Dose increase was well tolerated and full remission was achieved without an increased rate of adverse events.
