Abstract

TNF-receptor associated periodic syndrome (TRAPS) is a rare, dominantly inherited periodic fever syndrome due to mutations of the TNFRSF1A gene. The IL-1 receptor antagonist anakinra has been reported to be an efficacious daily treatment. Canakinumab (CAN) is a fully human monoclonal selective anti-IL-1β antibody with a T1/2 of ~4 wks. Interim clinical and PK data of CAN treatment in patients with active TRAPS are presented.

Highlights

  • TNF-receptor associated periodic syndrome (TRAPS) is a rare, dominantly inherited periodic fever syndrome due to mutations of the TNFRSF1A gene

  • Primary endpoint was complete or almost complete response at Day 15 based on physician assessed absent or minimal TRAPS signs/symptoms and normal or ≥70% reduced CRP and/or SAA

  • Population PK analysis was performed using NONMEM based on CAN concentrations determined by ELISA from blood samples collected at prespecified times points during the first month, at each pre-dose of CAN, and at flares thereafter
