Rilonacept is a dimeric fusion protein consisting of the ligand-binding domains of the extracellular portions of the human interleukin-1 receptor component (IL-1R1) and IL-1 receptor accessory protein (IL-1RAcP) linked in-line to the fragment-crystallizable portion (Fc region) of human IgG1 that binds and neutralizes IL-1.[2]
Rilonacept was given an "orphan drug" status by the United States Food and Drug Administration and is used for the treatment of cryopyrin-associated periodic syndromes (CAPS), including familial cold autoinflammatory syndrome, Muckle–Wells syndrome and neonatal onset multisystem inflammatory disease (It is not approved in the U.S. on this indication).[3]
On May 8th, 2012 an FDA Advisory Panel voted 11-0 against the approval of rilonacept for the treatment of gout, stating that the benefits did not outweigh the risks associated with the drug.[4]
