Canakinumab for the treatment of cryopyrin-associated periodic syndromes.

Familial cold-induced autoinflammatory syndrome, Muckle-Wells syndrome and neonatal-onset multisystem inflammatory disease make up cryopyrin-associated periodic syndromes (CAPS). These are autoinflammatory inherited disorders caused by autosomal dominant gain-of-function mutations in the NLRP3 gene, located on chromosome 1q44. Cryopyrin/NALP3/NLRP3 is an essential component of intracellular inflammasomes that activate caspase-1, which in turn converts interleukin-1beta (IL-1beta) to its active form. IL-1beta is a potent cytokine that activates diverse elements of the immune and inflammatory systems leading to the pathogenic changes characteristic of CAPS. There is therefore much interest in the development of IL-1beta blocking agents as novel biologic treatments for these conditions. Canakinumab (ACZ-885; Ilaris, Novartis Pharma) is a fully humanized monoclonal antibody (mAb) specific for IL-1beta and is indicated for a wide range of inflammatory disorders including CAPS. This review will assess the utility of canakinumab as a treatment for CAPS. Copyright 2009 Prous Science, S.A.U. or its licensors. All rights reserved.
