Canakinumab is a recombinant, human anti-human-IL-1β monoclonal antibody that belongs to the IgG1/κ isotype subclass. It is expressed in a murine Sp2/0-Ag14 cell line and comprised of two 447- (or 448-) residue heavy chains and two 214-residue light chains, with a molecular mass of 145157 Daltons when deglycosylated. Both heavy chains of canakinumab contain oligosaccharide chains linked to the protein backbone at asparagine 298 (Asn 298). Canakinumab binds to human IL-1β and neutralizes its inflammatory activity by blocking its interaction with IL-1 receptors, but it does not bind IL-1alpha or IL-1 receptor antagonist (IL-1ra). Canakinumab is marketed under the brand name Ilaris and indicated for patients 4 years of age and older to treat Familial Cold Autoinflammatory Syndrome (FCAS) and Muckle-Wells Syndrome (MWS), which are both part of the Cryopyrin-Associated Periodic Syndromes (CAPS) as well as for patients 2 years of age and older to treat systemic juvenile idiopathic arthritis (SJIA). Clinical trials have established the administration of canakinumab every 2 weeks to be safe and effective, offering a considerable advantage over the existing treatment with the human IL-1 receptor antagonist, anakinra, which must be injected daily and which is often poorly tolerated by patients.

|Indication||Used in patients 4 years of age and older to treat Familial Cold Autoinflammatory Syndrome (FCAS) and Muckle-Wells Syndrome (MWS), which are both part of the Cryopyrin-Associated Periodic Syndromes (CAPS) as well as for patients 2 years of age and older to treat systemic juvenile idiopathic arthritis (SJIA).|
|Pharmacodynamics||Novartis AG has developed canakinumab as a subcutaneous injection and fully human mAb that neutralizes the bioactivity of human IL-1beta, which is involved in several inflammatory disorders. Canakinumab has promising clinical safety and pharmacokinetic properties, and demonstrated potential for the treatment of cryopyrin-associated periodic syndromes (CAPS), systemic juvenile idiopathic arthritis (SJIA), and possibly for other complex inflammatory diseases, such as rheumatoid arthritis, COPD disease and ocular diseases.|
|Mechanism of action||In inflammatory diseases involving Cryopyrin-Associated Periodic Syndromes (CAPS), interleukin-1 beta (IL-1β) is excessively activated and drives inflammation. The protein cryopyrin controls the activation of IL-1β, and mutations in cryopyrin's gene, NLRP-3, up-regulate IL-1β activation. Canakinumab is a human monoclonal anti-human IL-1β antibody of the IgG1/κ isotype. Canakinumab binds to human IL-1β and neutralizes its inflammatory activity by blocking its interaction with IL-1 receptors, but it does not bind IL-1α or IL-1 receptor antagonist (IL-1ra).|
|Absorption||The absolute bioavailability of subcutaneous canakinumab is estimated to be 70%.|

Produced by activated macrophages, IL-1 stimulates thymocyte proliferation by inducing IL-2 release, B-cell maturation and proliferation, and fibroblast growth factor activity. IL-1 proteins are involved in the inflammatory response, being identified as endogenous pyrogens, and are reported to stimulate the release of prostaglandin and collagenase from synovial cellsOrganism class: human
