FMF

To evaluate the efficacy on clinical symptoms in case of FMF attack among FMF patients resistant to Colchicine of * on demand anakinra treatment (100 mg/d from the prodromal phase of the attack until 24 hours of remission (during 7 days maximum) associated with daily colchicine. * compared to analgesic associated with daily colchicine in patients refusing continuous anti-IL-1 treatment.

The purpose of this study is to assess safety and efficacy of the long-term treatment with RPH-104 at doses of 80 or 160 mg once every 2 weeks (q2w) in patients with familial Mediterranean fever (FMF) with colchicine resistance or intolerance (i.e. colchicine resistant, crFMF), who completed the core study, during which they received at least one dose of RPH-104 (i.e. study patient population).

Autoinflammatory diseases (AID) are caused by innate immunity dysregulation. AID pathophysiology is only partly understood, especially in the case of unclassified AID. Mast cells (MC) are innate immune cells associated with a spectrum of disease between systemic mastocytosis and mast cell activation syndrome. The implication of MC has been shown in cryopyrin associated periodic syndrome (CAPS).Our aim is to evaluate the involvement of MC in AID by assessing clinical and biological signs of MC activation and studying cutaneous and digestive biopsies.
