• Should not donate eggs from Day 1 until the EOS Visit.
• Male participants must use condom if sexually active with females of childbearing potential. The female partner of a male participant who does not meet the definition of postmenopausal or permanently surgically sterile is considered of childbearing potential and is required to use a highly effective method of contraception (see Section 3.7) consistently from 30 days prior to Day 1 until the EOS visit of the male participant. Male participants who are surgically sterilized, performed at least 6 months prior to screening, may be enrolled. Male participants must also agree not to donate sperm from Day 1 until the EOS visit.
• No clinically significant findings as determined by medical history, and by results of physical examination, vital signs, ECG, thyroid ultrasound, and clinical laboratory tests obtained within 35 days prior to study treatment administration.

Критерии исключения

• History or presence of any clinically significant organ system disease that could interfere with the objectives of the study or the safety of the participants.
• History of immunological abnormality (i.e., primary or secondary immune suppression) that could interfere with the objectives of the study or the safety of the participants.
• Participants with a significant finding on history of thyroid conditions, thyroid function testing, thyroid antibody testing, or thyroid ultrasound giving reasonable suspicion of a condition that might interfere with the conduct or interpretation of the study.
• Presence or history of any abnormality or illness, which in the opinion of the investigator (or designee) may affect absorption, distribution, metabolism or elimination of the study treatment.
• Any screening laboratory evaluation outside the laboratory reference range that is judged by the investigator (or designee) to be clinically significant, including but not limited:

• Participants with eGFR < 80 mL/min/1.73m2 as determined by the CKD-EPI 2021 formula, at the Screening or Baseline visits.

• Major surgery or major traumatic injury within 3 months of Day 1. Participants must have also fully recovered from any surgery and/or its complications before initiating the study treatment.
• Malignancy or a history of malignancy prior to the Screening Visit (except for non-melanoma cutaneous malignancies which have been fully treated and completed post-treatment follow-up).

• Pregnant or lactating women.
• Cannot commit to full participation in all trial procedures.
• Any other circumstances that, in the Investigator (or designee) judgment, may increase the risk associated with the participant's participation in and completion of the study or could preclude the evaluation of the participant's response.
