Eligibility Criteria
You may qualify if:
- Diagnosed with familial cold autoinflammatory syndrome (FCAS) or Muckle-Wells syndrome (MWS) confirmed by:
- Clinical History: At least 2 typical clinical symptoms (e.g., urticarial skin rash, myalgia, arthralgia, recurrent fever, fatigue/malaise, conjunctivitis or other autoinflammatory symptoms) prior to the Screening Visit; AND
