Ascendis Pharma Announces Submission of Supplemental Biologics License Application to FDA for TransCon™ hGH for the Treatment of Adults with Growth Hormone Deficiency

COPENHAGEN, Denmark, Sept. 30, 2024 (GLOBE NEWSWIRE) — Ascendis Pharma A/S (Nasdaq: ASND) today announced it has submitted a supplemental Biologics License Application (sBLA) to the U.S. Food & Drug Administration (FDA) for TransCon hGH (marketed as SKYTROFA^® (lonapegsomatropin-tcgd) in the U.S. for pediatric growth hormone deficiency) for the treatment of adults with growth hormone deficiency (GHD).

“The sBLA submission for TransCon hGH for adult GHD supports our strategy to develop SKYTROFA into a blockbuster product through label expansion and build upon our value leadership position in the U.S. growth hormone market,” said Jan Mikkelsen, Ascendis Pharma’s President and Chief Executive Officer. “Growth hormone plays a vital role in human health at all ages, and, with research showing that the majority of adults living with growth hormone deficiency are not currently treated for this condition, we believe once weekly TransCon hGH could provide a new potential treatment option to address this unmet medical need.”

The submission is based on results from foresiGHt, a Phase 3 randomized, parallel-arm, placebo-controlled (double-blind) and active-controlled (open-label) trial that compared the efficacy and safety of weekly TransCon hGH with weekly placebo and daily hGH in adults with GHD. The trial evaluated 259 adults with GHD aged 23 to 80 years old, randomized 1:1:1, titrated to receive a target fixed dose of TransCon hGH, placebo, or daily hGH based on age and oral estrogen intake with approximately equivalent hGH mg/week for TransCon hGH and daily hGH. TransCon hGH demonstrated superiority on its primary efficacy and key secondary efficacy endpoints at Week 38, with TransCon hGH-treated patients showing a statistically significant reduction from baseline in trunk fat and increase in total body lean mass at Week 38 compared to placebo.

TransCon hGH was generally safe and well tolerated, with no discontinuations related to study drug and with comparable safety and tolerability to daily hGH.

About Adult Growth Hormone Deficiency
Growth hormone plays an essential role in the health of children and adults, promoting normal growth in children and maintenance of normal body composition and cardiometabolic health throughout adulthood. In adults, growth hormone boosts protein production, promotes fat utilization, enhances muscle mass, and helps regulate blood sugar levels. Adult GHD is a condition in which an individual’s body does not produce enough growth hormone. Symptoms and morbidity can include central obesity, metabolic syndrome, decreased bone density, alterations in lipid profile and markers of cardiovascular risk, fatigue, general weakness, lack of muscle tone, and psychological symptoms such as cognitive impairment, social isolation, lack of motivation, and depression.¹
