Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Participants who have a confirmed diagnosis of Graves' disease with active hyperthyroidism, with or without active Graves' orbitopathy at the time of screening.
* A subset of participants will have a diagnosis of active Graves' orbitopathy, as confirmed by ophthalmic exam at screening and a clinical activity score (CAS) ≥3 for the most severely affected eye, and associated with one or more of the following: lid retraction ≥2 mm, moderate or severe soft tissue involvement, proptosis ≥2 mm, and/or intermittent or constant diplopia.
* Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

Exclusion Criteria

* History of hyperthyroidism not caused by Graves' disease (eg, hyperthyroidism due to toxic multinodular goiter, autonomous thyroid nodule, acute inflammatory thyroiditis).
* History of thyroid storm or at high risk of developing thyroid storm as determined by evaluating clinician.
* Enlarged thyroid goiter causing upper airway obstruction and/or requiring surgical intervention during the study period.
* For participant with Graves' orbitopathy, requires immediate surgical ophthalmological intervention or is planning corrective surgery/irradiation during the course of the study.
* Sight threatening Graves' orbitopathy or decreased visual acuity due to optic neuropathy within the last 6 months.
* Corneal decompensation unresponsive to medical management.
* Onset of Graves' orbitopathy symptoms \>9 months prior to baseline. The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
