Male and female subjects aged >= 18 years and = 2, considered to be in active disease. (2): CAPS: Subjects meeting the diagnostic criteria for CAPS, with NLRP3 mutation and requiring treatment, and a Physician Global Assessment (PGA, 0–4 scale) >= 2, considered to be in active disease. (3): Schnitzler syndrome: Subjects meeting the diagnostic criteria for SchS, with a Physician Global Assessment (PGA, 0–4 scale) >= 2, considered to be in active disease. (4): FMF: Subjects meeting the Tel Hashomer diagnostic criteria (1997), with a prior attack frequency of at least 1 per month. For patients receiving biologic therapy, this criterion applies to the last 12 months before initiation of any biologic therapy, and a Physician Global Assessment (PGA, 0–4 scale) >= 2, considered to be in active disease. And meeting one of the following: Active disease despite colchicine treatment (at least 1.5 mg to 3.0 mg/day). Patients currently on colchicine will remain on a stable dose during the study. Colchicine intolerance (at least 1.5 mg to 3.0 mg/day). 5. .If receiving NSAID therapy: only one NSAID at a stable dose for >= 1 week before enrollment (dose <= maximum recommended daily dose) is allowed (excluding temporary antipyretic use with <= 1 dose per day and <= 2 cumulative days within 2 weeks before dosing), and the dose will not be increased during the study. 6. .If receiving glucocorticoid therapy: stable dose <= 10 mg/day (prednisolone or equivalent) for at least 2 weeks before enrollment, and the dose will not be increased during the study. 7. If receiving disease-modifying antirheumatic drug (DMARD) therapy: stable dose for at least 3 months before enrollment, and the dose will not be increased during the study. 8. Women of childbearing potential must use an effective contraceptive method and have a negative pregnancy test before study initiation.
