入选标准

  • Are ≥ 18 and ≤ 75 years of age at the time of signing the informed consent form (ICF)
  • Have a prior diagnosis of GD documented
  • Have a TSH value < 0.1 mIU/L as assessed by the local laboratory at the Screening Visit
  • Meet both of the following at the Screening Visit: a. Have been on ATD for ≥ 3 months in the period immediately preceding the Screening Visit and the following: i. Are on ATD at the Screening Visit with an ATD dose ≥ 20 mg/day methimazole or equivalent (i.e., ≥ 30 mg/day carbimazole, ≥ 200 mg/day propylthiouracil) for the 4-week period immediately preceding the Screening Visit. ii. Are anticipated to be on a stable dose of ATD for the 4-week period immediately preceding Randomization. b. Have been on ATD for ≥ 6 months in the period immediately preceding the Screening Visit and both of the following: i. Have been treated with ≥ 15 mg/day methimazole or equivalent (i.e., ≥ 20 mg/day carbimazole, ≥ 150 mg/day propylthiouracil) at any point during the participant's treatment history. ii. Are on ATD at the Screening Visit with an ATD dose ≥ 10 mg/day methimazole or equivalent (i.e., ≥ 15 mg/day carbimazole, ≥ 100 mg/day propylthiouracil) for the 4-week period immediately preceding the Screening Visit. iii. Are anticipated to be on a stable dose of ATD for the 4-week period immediately preceding Randomization.

排除标准

  • Have previously been treated with RAI therapy or have undergone total thyroidectomy.
  • Have a T3 (Total T3 or FT3, as available and per standard of care at local laboratory) or FT4 value < LLN as assessed by the local laboratory at the Screening Visit
  • Have received levothyroxine, desiccated thyroid extract, or T3 at any dose within 6 weeks of the Screening Visit. Note: Participants receiving block-and-replace treatment are not eligible.
  • Have a history of hyperthyroidism not caused by GD (e.g., toxic adenoma or toxic multinodular goiter) and/or history of thyroid storm within 6 months of the Screening Visit
  • Have an autoimmune disease other than GD requiring treatment that, in the Investigator's judgment, puts the participant at undue risk.
  • Have moderate-to-severe active TED and are expected to require immediate surgical intervention and/or are planning corrective surgery/irradiation or medical therapy for TED during study participation.
