About this study

This study is being conducted to look at the effect YB-101 has on thyroid function. This study will also evaluate how safe and well tolerated YB-101 is and how it is distributed through the body. The study consists of a part 1, blinded treatment period, and a part 2 double-blinded treatment period. Participants will receive YB-101 or Placebo subcutaneously. Participants who participate in Part 1 can not participate in Part 2. Participants will complete 34-39 in-clinic visits in Part 1 or Part 2 over an approximate 40 week period.
