Ascendis Pharma BLA for Growth Hormone Deficiency

Share

FDA has accepted an Ascendis Pharma BLA for its TransCon hGH (lonapegsomatropin), an investigational long-acting prodrug of somatropin (human growth hormone) for treating pediatric growth hormone deficiency. The submission is supported by data from eight clinical trials evaluating safety and efficacy in more than 400 subjects, Ascendis says. The agency has set a user fee review action target date of 6/25/2021.

 

The company says that the once-weekly injectable biologic is designed to release somatropin with the same mode of action and distribution as once-daily somatropin products. TransCon refers to “transient conjugation” and TransCon molecules have three components: an unmodified parent drug, an inert carrier that protects it, and a linker that temporarily binds the two, it says. “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,” Ascendis says.
