Ascendis Pharma A/S is a Denmark‐based biopharmaceutical company focused on developing innovative therapies for rare endocrine diseases. Founded in 2015 and headquartered in Hellerup, the company leverages its proprietary TransCon drug delivery platform to create long‐acting prodrugs designed to improve safety, efficacy and patient convenience. Ascendis Pharma maintains research and development operations in Europe and the United States, with clinical studies spanning North America, Europe and Asia.
The company’s lead product, lonapegsomatropin (Skytrofa®), is a once‐weekly growth hormone therapy approved by the U.S. Food and Drug Administration for the treatment of pediatric growth hormone deficiency. By transiently conjugating active hormone to a carrier molecule, the TransCon platform allows controlled release of the therapeutic agent over time, reducing injection frequency and helping to maintain more consistent drug exposure.
Beyond growth hormone deficiency, Ascendis Pharma is advancing a pipeline of product candidates aimed at other rare endocrine disorders. TransCon parathyroid hormone (PTH) is in clinical development for hypoparathyroidism and has demonstrated positive proof‐of‐concept data. The company is also investigating TransCon CNP for the treatment of achondroplasia, a form of dwarfism, and pursuing additional indications in both endocrine and broader metabolic diseases.
Ascendis Pharma’s management team brings together experienced professionals in drug development, regulatory affairs and commercial strategy. The company continues to expand its global footprint through strategic collaborations and partnerships, with the goal of delivering transformative therapies to patients with underserved conditions.
