DrugBank Description: Rilonacept is a dimeric fusion protein consisting of portions of IL-1R and the IL-1R accessory protein linked to the Fc portion of immunoglobulin G1. Rilonacept functions as an interleukin 1 inhibitor and is used in the treatment of CAPS, also known as cryopyrin-associated periodic syndromes, including familial cold auto-inflammatory syndrome (FCAS) and Muckle-Wells Syndrome (MWS), in adults and children greater than 12 years old.
CAS Number: 501081-76-1

DrugBank Indication: Rilonacept is currently used in the treatment of cryopyrin-associated periodic syndrome. In May 2012, an advisory panel for the FDA voted 11-0 against the use of Rilonacept for the treatment of gout.
DrugBank Pharmacology: Treatment with Rilonacept resulted in decreased levels of mean C-Reactive Protein (CRP) and Serum Amyloid A (SAA). Higher levels of CRP and SAA are associated with inflammatory disease activity found in patients with Cryopyrin-Associated Periodic Syndromes.
DrugBank MoA: CAPS refer to rare genetic syndromes generally caused by mutations in the NLRP-3 gene (also known as Cold-Induced Auto-inflammatory Syndtrome-1 ). CAPS disorders are inherited in an autosomal dominant pattern with male and female offspring equally affected. Fever, urticaria-like rash, arthralgia, myalgia, fatigue, and conjunctivitis are features common to all disorders. In most cases, inflammation in CAPS is associated with mutations in the NLRP-3 gene which encodes the protein cryopyrin, an important component of the inflammasome. Cryopyrin regulates the protease caspase-1 and controls the activation of interleukin-1 beta (IL-1β). Mutations in NLRP-3 result in an overactive inflammasome resulting in excessive release of activated IL-1β that drives inflammation. Rilonacept blocks IL-1β signaling by acting as a soluble decoy receptor that binds IL-1β and prevents its interaction with cell surface receptors. Rilonacept also binds IL-1α and IL-1 receptor antagonist (IL-1ra) with reduced affinity. By binding IL-1, rilonacept prevents the activation of IL-1 receptors, thus reducing inflammatory responses and other effects related to an excess of IL-1.
Targets: Interleukin-1 beta binder; Interleukin-1 alpha binder; Interleukin-1 receptor antagonist protein binder
