A Research Study to Compare Somapacitan Once a Week With Norditropin® Once a Day in Children Who Need Help to Grow
United States, Austria, Belgium412 participantsStarted 2022-08-10
Plain-language summary
The study compares two medicines for treatment of children born small and who stay small, or with Turner Syndrome, Noonan Syndrome, or idiopathic short stature. The purpose of the study is to see how well treatment with somapacitan works compared to treatment with Norditropin®. Somapacitan is a new medicine, and Norditropin® is a medicine doctors can already prescribe in some countries. The study will last for upto 5.5 years. The participants will either get somapacitan once a week up to 5.5 years or Norditropin® once a day for 1 year followed by somapacitan once a week for up to 4.5 years. Which treatment the participants get is decided by chance.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Since this trial is comparing a once-weekly injection of somapacitan against the standard once-daily Norditropin, is there any evidence so far about whether the weekly schedule is as effective or as safe for my child's specific condition — whether that's Turner syndrome, Noonan syndrome, SGA, or idiopathic short stature?
2This is a Phase 3 trial, which I understand means it's in later-stage testing — does that mean there's enough safety data available for me to feel reasonably informed about the risks before considering it for my child?
3The trial is 'active but not recruiting' — does that mean my child can no longer join, and if so, are there similar studies or compassionate use options we should explore instead?
4Since the study measures height velocity separately for each condition, would the results most relevant to my child's diagnosis give us a clearer picture of whether this weekly treatment could be right for them compared to the daily standard?
5How does the convenience of a once-weekly injection weigh against sticking with the proven once-daily Norditropin routine my child may already be on or considering — and would switching approaches at this stage make sense for us?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Height velocity reported separately for small for gestational age (SGA), Turner syndrome (TS), Noonan syndrome (NS) and idiopathic short stature (ISS)
Timeframe: From baseline (week 0) to visit 7 (week 52)
. Impaired height defined as at least 2.5 standard deviations below the mean height for chronological age and sex at screening according to the standards of Centers for Disease Control and Prevention.
. Impaired height velocity defined as annualized height velocity below the 50th percentile for chronological age and sex according to the standards of Prader calculated over a time span of minimum 6 months and maximum 18 months prior to screening.
Exclusion criteria
. Known or suspected hypersensitivity to study intervention(s) or related products.
. Previous randomization into same sub-study in this study.
. Receipt of any investigational medicinal product within 3 months before screening or participation in another clinical study at the time of randomization.
. Children with suspected or confirmed growth hormone deficiency according to local practice.
. laboratory of
. fasting plasma glucose above or equal to 126 mg/dL (7.0 mmol/L) or
. HbA1c above or equal to 6.5%.
. Current inflammatory diseases requiring systemic corticosteroid treatment for longer than 2 consecutive weeks within the last 3 months prior to screening.
