This new therapy, developed using the innovative TransCon technology platform, is designed to provide continuous daily exposure to parathyroid hormone over a 24-hour period. Hypoparathyroidism is a rare endocrine disorder that impairs calcium and phosphate balance, affecting multiple organs and the quality of life for thousands of patients in the U.S. The FDA based its approval on robust clinical data from Phase 2 and Phase 3 trials, which demonstrated the potential of YORVIPATH to address the underlying cause of the disease. In addition to this regulatory milestone, Ascendis Pharma is committed to supporting patients through dedicated access and assistance programs, promising an important new option for managing this chronic condition.
