Kiniksa Pharma’s Arcalyst OK’d for Pericarditis
FDA has approved a Kiniksa Pharmaceuticals NDA for Arcalyst (rilonacept) injection to treat recurrent pericarditis and reduce the risk of recurrence in adults and children 12 years and older. Recurrent pericarditis involves inflammation of the pericardium, a thin tissue sac surrounding the heart, which can cause chest pain, an agency release says.
Approval was based on data from an 86-patient trial and the primary effectiveness endpoint was the time to first pericarditis recurrence. “Results showed that 23 (74%) patients in the placebo arm had a recurrence compared to two (7%) patients on Arcalyst, both of whom had temporarily stopped treatment,” FDA says. “Serious, life-threatening infections have been reported in patients taking Arcalyst.” Patients with an infection should not take the drug, and they should avoid live vaccines while taking the drug.
Arcalyst was first approved in 2008 to treat cryopyrin-associated periodic syndromes, including familial cold auto-inflammatory syndrome, and Muckle-Wells syndrome in patients 12 years and older.
