Additional discovery programs address a variety of endocrine conditions such as neuroendocrine tumors, Graves’ disease (including Graves’ hyperthyroidism and Graves’ orbitopathy, or thyroid eye disease), polycystic kidney disease, hyperparathyroidism, diabetes, obesity, and GPCR-targeted oncology indications.
