Hyperthyroid state requiring medication after receiving ≥ 2 times of radioiodine therapy (with the last dose of radioiodine administered at least 6 months prior); c. Relapse ≥ 2 times after cessation of medication upon meeting the criteria for treatment discontinuation
• Serum TRAb ≥ 3 times greater than normal range (≥ 5 IU/L)
• Positive expression of CD19 on peripheral blood B cells determined by flow cytometry
• Participation in this clinical study is willing to sign an informed consent with good compliance with treatment and follow-up; (Criteria for treatment discontinuation is define as receiving continuous anti-thyroid drug therapy for ≥18 months, and maintaining euthyroid status for ≥6 months, plus negative TRAb and TSI.
