COPENHAGEN, Denmark, April 21, 2021 (GLOBE NEWSWIRE) -- Ascendis Pharma A/S (Nasdaq: ASND), a biopharmaceutical company that utilizes its innovative TransCon technologies to address unmet medical needs, today announced presentations featuring TransCon hGH (lonapegsomatropin) at two upcoming medical conferences: Pediatric Endocrinology Nursing Society (PENS) national conference, taking place virtually April 21-23, and the Pediatric Endocrine Society (PES) annual meeting, taking place virtually April 30 May 3, 2021.

We look forward to presenting the latest data on lonapegsomatropin, our investigational once-weekly growth hormone, at PENS and PES, two of the leading medical conferences focused on pediatric endocrinology, said Mark Bach, M.D., Ph.D., Senior Vice President of Endocrine Medical Sciences at Ascendis Pharma.

We will present the two-year follow-up data for lonapegsomatropin which show durable results in children treated for pediatric growth hormone deficiency (GHD). In addition, we will present a model which can estimate the average weekly insulin-like growth factor 1 (IGF-1) level from a single IGF-1 sample in children with GHD treated with lonapegsomatropin. This tool may help physicians effectively manage patients on lonapegsomatropin therapy following regulatory approval, continued Dr. Bach.

About TransCon Technology

TransCon refers to transient conjugation. The proprietary TransCon platform is an innovative technology to create new therapies that are designed to optimize therapeutic effect, including efficacy, safety and dosing frequency. TransCon molecules have three components: an unmodified parent drug, an inert carrier that protects it, and a linker that temporarily binds the two. When bound, the carrier inactivates and shields the parent drug from clearance. When injected into the body, physiologic conditions (e.g., pH and temperature) initiate the release of the active, unmodified parent drug in a predictable manner. Because the parent drug is unmodified, its original mode of action is expected to be maintained. TransCon technology can be applied broadly to a protein, peptide or small molecule in multiple therapeutic areas, and can be used systemically or locally.
