|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). The biological activity of canakinumab is measured by comparing its inhibition of IL-1β-dependent expression of the reporter gene luciferase to that of a canakinumab internal reference standard, using a stably transfected cell line.

Investigated for use/treatment in rheumatoid arthritis, juvenile rheumatoid arthritis, inflammatory disorders (unspecified), and autoimmune diseases.
Novartis AG is developing canakinumab, an intravenously or subcutaneously infused, 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) and possibly for other complex inflammatory diseases, such as rheumatoid arthritis, systemic-onset juvenile idiopathic arthritis (SoJIA), COPD disease and ocular diseases. Early 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.
mechanism of action
Canakinumab is a human monoclonal anti-human IL-1β antibody of the IgG1/κ isotype. Canakinumab binds to human IL-1β and neutralizes its activity by blocking its interaction with IL-1 receptors, but it does not bind IL-1α or IL-1 receptor antagonist (IL-1ra).
The absolute bioavailability of subcutaneous canakinumab is estimated to be 70%.
