Yarrow Bioscience, Inc. is a clinical-stage biotechnology company focused on developing transformative therapies for autoimmune thyroid diseases. The Company is developing YB-101, an anti-thyroid stimulating hormone receptor (TSHR) monoclonal antibody designed to directly and rapidly disrupt the central mechanism of both Graves' Disease (GD) and Thyroid Eye Disease (TED), offering a single targeted treatment to address both diseases. By blocking TSHR, the common target of autoantibodies in both the thyroid and the eye, YB-101 has the potential to rapidly arrest the disease process and provide improved efficacy and safety versus the standard of care and other mechanisms in development. YB-101 is designed for convenient subcutaneous administration, with the potential for infrequent dosing and future autoinjector presentations. The Company has initiated dosing in a Phase 2a/2b trial evaluating YB-101 in patients with GD, with or without concurrent TED.
