On December 16, 2024, the applicable regulatory waiting period for the Company’s agreement with Novo Nordisk expired, enabling the close of the previously announced collaboration agreement for the development and commercialization of TransCon technology-based products in metabolic and cardiovascular diseases.

Under the terms of the agreement, Novo Nordisk received an exclusive worldwide license to the TransCon technology platform to develop, manufacture and commercialize Novo Nordisk proprietary products in metabolic diseases (including obesity and type 2 diabetes) and a product-by-product exclusive license in cardiovascular diseases. The lead program in the collaboration is a once-monthly GLP-1 receptor agonist product candidate that will initially target obesity and type 2 diabetes.

With the closing of the agreement, Ascendis is eligible to receive a $100 million milestone payment from Novo Nordisk. Additional details about the collaboration can be found in the Company’s Form 6-K furnished with the Securities and Exchange Commission on November 4, 2024.
