This once-weekly, subcutaneous injection is a pegylated prodrug of somatropin, designed for sustained release of the active hormone. Skytrofa was previously approved for pediatric patients with growth failure due to insufficient growth hormone secretion.
The FDA’s approval of SKYTROFA for adult GHD was based on results from foresiGHt, a Phase 3 randomized, parallel-arm, placebo-controlled (double-blind) and active-controlled (open-label) clinical trial that compared the efficacy and safety of weekly TransCon hGH with weekly placebo and daily somatropin in adults with GHD.
“The abnormal body composition, dyslipidemia, and insulin resistance that are the hallmarks of adult GHD predispose affected individuals to serious medical complications such as metabolic syndrome, increased cardiovascular risk, and impaired quality of life – including cognitive dysfunction, depression, anxiety, sleep disturbance, and reduced physical and mental drive. Despite this, adherence to daily somatropin injections that have been the standard of care for more than 25 years remains a problem,” said Kevin Yuen, M.D., Barrow Neurological Institute, University of Arizona College of Medicine and Creighton University School of Medicine in Phoenix, Arizona. “It is no surprise that patients are looking for a less burdensome treatment regimen, and a new treatment option such as SKYTROFA, with once-weekly injection and its unique release of unmodified somatropin, is expected to help improve both real-world adherence and overall outcomes.”
“Our market research shows SKYTROFA is the treatment of choice for pediatric GHD among patients and physicians, and we are pleased to expand its availability in the United States for the treatment of adults initiating therapy or switching from another growth hormone therapy,” said Jan Mikkelsen, President and Chief Executive Officer at Ascendis Pharma. “This important milestone is the first of many planned label expansions supporting our goal to become the leading endocrinology rare disease company.”

you are a child with closed bone growth plates

SKYTROFA may cause serious side effects, including:
serious allergic reactions. Get medical help right away if you have swelling of the face, mouth, tongue, or throat or trouble breathing
high risk of death in people who have critical illnesses caused by heart or stomach surgery, trauma, or serious breathing problems
increased risk of growth of an existing tumor or cancer, or increased risk of a previous tumor or cancer returning in people who were treated with radiation to the brain or head as children and who developed low growth hormone problems
Your healthcare provider will need to monitor for the growth or return of a tumor or cancer. Contact your healthcare provider if you start to have sudden changes in behavior, headaches, vision problems, or changes in moles, birthmarks, or skin color

decrease in a hormone called cortisol. Your healthcare provider will do blood tests to check your cortisol levels
decrease in thyroid hormone levels. Decreased thyroid hormone levels may affect how well SKYTROFA works. Your healthcare provider will do blood tests to check your thyroid hormone levels
hip and knee pain or a limp in children (slipped capital femoral epiphysis). This may lead to a serious condition where bone tissue dies due to a lack of blood supply (osteonecrosis). Get medical help right away for children who develop a limp or have hip or knee pain
worsening of curvature of the spine in children (scoliosis)
severe and constant abdominal pain. This could be a sign of pancreatitis. Tell your healthcare provider about any new abdominal pain
