Trial Summary

What is the purpose of this trial?

This trial is testing somapacitan, a new growth hormone medicine, in children who have low levels of growth hormone. These children include those born small for their age or with conditions like Turner syndrome, Noonan syndrome, or idiopathic short stature. Somapacitan is given as an injection to help them grow better. Somapacitan is a long-acting growth hormone derivative developed for periodic administration, already approved for use in adult GH deficiency in the USA and Japan.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you are on systemic corticosteroids or high-dose inhaled glucocorticoids, you may not be eligible. It's best to discuss your specific medications with the study doctor.

What data supports the idea that Somapacitan for Growth Hormone Deficiency in Children is an effective drug?

The available research shows that Somapacitan, a once-weekly drug, is effective for treating children with Growth Hormone Deficiency. Studies indicate that it is well-tolerated and provides effective growth hormone replacement. Specifically, the REAL4 trial demonstrated that children receiving Somapacitan experienced positive outcomes over a two-year period, and it was effective when children switched from daily growth hormone treatments to this weekly option. This suggests that Somapacitan is a convenient and effective alternative to daily treatments.12345

What data supports the effectiveness of the drug Somapacitan for treating growth hormone deficiency in children?

Research shows that Somapacitan, a long-acting growth hormone, is effective and well-tolerated in children with growth hormone deficiency, with studies indicating successful results from once-weekly dosing.12345

What safety data is available for Somapacitan in treating growth hormone deficiency?

Somapacitan has been evaluated in several studies for its safety and efficacy. It has been found to be well-tolerated in children with growth hormone deficiency in the Phase 3 REAL4 trial. Additionally, Phase I trials have shown it to be well-tolerated in both children and adults, including those with growth hormone deficiency. These studies support its use as a once-weekly treatment.12456

Is Somapacitan safe for use in humans?

Somapacitan has been well-tolerated in both children and adults with growth hormone deficiency, according to several studies. It has been tested in various trials and found to be safe for use with a once-weekly dosing schedule.12456

Is the drug Somapacitan a promising treatment for growth hormone deficiency in children?

Yes, Somapacitan is a promising drug for treating growth hormone deficiency in children. It is a long-acting growth hormone that can be given once a week instead of daily, making it more convenient for children and their families. Studies show it is effective and well-tolerated, which means it works well and is safe for use.13457

How is the drug Somapacitan different from other treatments for growth hormone deficiency in children?

Somapacitan is unique because it is a long-acting growth hormone that only needs to be administered once a week, unlike other treatments that require daily injections. This can reduce the treatment burden for children and their families.13457

Eligibility Criteria

This trial is for children aged 10-18 with Turner Syndrome, Noonan Syndrome, or born small for gestational age. They must have open growth plates and a specific height deficit. Children can't join if they have significant health issues affecting growth, diabetes, cancer history, or need certain steroid treatments.

Inclusion Criteria

My child is small for their age with growth plates still open and a bone age under 14 (if female) or under 16 (if male).
My child has Turner Syndrome confirmed by specific genetic tests and hasn't started growth hormone treatment.
My child has open growth plates and is under the age limit for their gender.

Findings from Research

Somapacitan, a long-acting growth hormone derivative, demonstrated sustained efficacy in promoting height velocity in children with growth hormone deficiency over a 2-year period, with similar growth rates observed after switching from daily growth hormone treatment.
The treatment was well tolerated with no safety issues reported, and a significant majority (90%) of patients and caregivers preferred the once-weekly somapacitan regimen over daily injections, indicating a favorable patient experience.
Effective GH Replacement With Somapacitan in Children With GHD: REAL4 2-year Results and After Switch From Daily GH.Miller, BS., Blair, JC., Rasmussen, MH., et al.[2023]
Somapacitan, a once-weekly growth hormone treatment, showed similar efficacy to daily growth hormone (GH) in increasing height velocity in children with growth hormone deficiency over a 52-week period, confirming its noninferiority.
Both somapacitan and daily GH had comparable safety profiles, with low rates of injection-site reactions, and somapacitan was associated with a greater reduction in treatment burden for patients.
Weekly Somapacitan is Effective and Well Tolerated in Children With GH Deficiency: The Randomized Phase 3 REAL4 Trial.Miller, BS., Blair, JC., Rasmussen, MH., et al.[2023]
Somapacitan, a growth hormone derivative designed for weekly use, demonstrated effective pharmacokinetic properties across rats, minipigs, and monkeys, with sustained IGF-I levels for up to 10 days after a single dose.
In hypophysectomised rats, somapacitan led to a significant dose-dependent increase in body weight and IGF-I levels, indicating its potential efficacy in promoting growth in individuals with growth hormone deficiency.
