Ascendis Pharma Regains Full Rights to TransCon Metabolic and Cardiovascular Programs After Novo Nordisk Split
Ascendis Pharma (ASND) will regain full rights to its TransCon metabolic and cardiovascular programs, including obesity treatments, after ending its collaboration with Novo Nordisk. The termination, effective September 14, 2026, returns all licenses to Ascendis without ongoing financial obligations. This move may impact the company's strategic options and market positioning, though it also introduces development and regulatory risks.
