The purpose of this study is to investigate the effects of investigational medications on thyroid cancer. Thyroid cancer is a type of cancer that starts in the thyroid gland, which is located in the neck and produces hormones that regulate metabolism. This study aims to understand both the positive and negative effects of the investigational medications when used alone or in combination.

Participants in this study may receive either one or both of the investigational medications. The study will monitor participants for any changes in their condition and any side effects they may experience. This information will help researchers learn more about the safety and effectiveness of the treatments.

• Who can participate: Specific eligibility criteria, including age and key factors, are not provided.
• Study details: Participants will be assigned to receive either one or both investigational medications. A placebo may be used, which is an inactive substance that looks like the investigational medicine but does not contain any medicine.
