Session Information
Session Type: ACR Poster Session A
Session Time: 9:00AM-11:00AM
Background/Purpose: Canakinumab (CAN) is indicated for
the treatment of cryopyrin-associated periodic syndrome (CAPS) in patients aged
≥2 years.1,2 However, the efficacy of
CAN has not yet been studied in infants. Here we present the efficacy and
safety of CAN in patients with CAPS aged <24 months.
Methods: Patients aged 28 days to 4 years
with CAPS received CAN at 2 to 12 mg/kg every 4 or 8 weeks for 56 weeks. Efficacy
was evaluated by complete response (clinical response and normal C-reactive
protein [CRP] levels) and subsequent relapse. Safety assessments included
adverse events (AEs).
Results: Of 17 patients enrolled, 6 were aged
<24 months (44 days to 5 months). The phenotypic distribution of patients
aged <24 months was: familial cold autoinflammatory syndrome (FCAS, n=1),
Muckle–Wells syndrome (MWS, n=4), and neonatal-onset multisystem inflammatory
disease (NOMID, n=1). All 17 patients achieved a clinical response, and 16
achieved a complete response, with 5/6 patients <24 months of age achieving
a complete response. One patient aged 1 year with persistently elevated CRP
levels did not achieve complete response (Table). Of the patients with a
complete response, 4 (2 MWS and 2 NOMID) subsequently relapsed; however, all
regained complete response 2 (1 MWS; 1 NOMID) with and 2 (1 MWS; 1 NOMID)
without dose escalation. Seven patients required dose escalation to achieve
and/or maintain their responses. The proportion of complete responders without
a relapse was higher in the <24 months age group (5/5, 88.9%) versus ≥24
months (7/11, 63.6%). The most common AEs were infections, typically involving
the upper respiratory tract. Four patients experienced a serious AE (SAE), with
no SAE occurring more than once. No patient discontinued due to an AE.

Conclusion: Canakinumab is an effective treatment
for patients with CAPS aged as young as 44 days. The safety profile of
canakinumab was acceptable in younger patients and similar to that observed for
older patients.
