RILONACEPT

DESCRIPTION

INDICATION

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.

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.

PHARMACODYNAMICS

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.

MECHANISM OF ACTION

CAPS refer to rare genetic syndromes generally caused by mutations in the NLRP-3 [Nucleotide-binding domain, leucine rich family (NLR),

pyrin

domain containing 3] gene (also known as Cold-Induced Auto-inflammatory Syndtrome-1 [CIAS1]). 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.

TARGETInterleukin-1 beta,Interleukin-1 alpha,Interleukin-1 receptor antagonist protein

Rilonacept

AKA ArcalystRilonacept

is a

dimeric

fusion protein consisting of the

ligand-binding domains of the extracellular portions of the human interleukin-1 receptor component (IL-1RI) and IL-1 receptor accessory protein (IL-1RAcP) linked in-line to the Fc portion of human IgG1. Rilonacept has a molecular weight of approximately 251 kDa. Rilonacept is expressed in recombinant Chinese hamster ovary (CHO) cells.

SCDOSAGE:Loading dose: 320 mg delivered as two, 2

mL, subcutaneous injections of 160 mg each given on the same day at two different sites.Dosing should be continued with a once-weekly injection of 160 mg administered as a single, 2-mL, subcutaneous injection.

Rilonacept

should not be given more often than once weekly.

VIAL:ARCALYST (

rilonacept) is supplied in single-use, 20-mL glass vials containing a sterile, white to off-white, lyophilized powder. Each vial of ARCALYST (rilonacept) is to be reconstituted with 2.3 mL of Sterile Water for Injection. A volume of up to 2

mL

can be withdrawn, which is designed to deliver 160 mg for subcutaneous administration only. The resulting solution is viscous, clear,

colorless

to pale yellow, and essentially free from particulates. Each vial contains 220 mg rilonacept (80 mg/ 1mL after reconstitution), histidine, arginine, polyethylene glycol 3350, sucrose, and glycine at a pH of 6.5±0.3. No preservatives are present.

ADVERSE REACTION:Fever, chills, sore throat, flu symptoms;easy bruising or bleeding (nosebleeds, bleeding gums);nausea and vomiting, loss of appetite;mouth sores; orunusual weakness.
