About this study

Official title: A Study Evaluating the Safety and Efficacy of Once-weekly Dosing of Somapacitan in a Basket Study Design in Paediatric Participants With Short Stature Either Born Small for Gestational Age or With Turner Syndrome, Noonan Syndrome or Idiopathic Short Stature

The purpose of this study is to find out if somapacitan is safe and how well somapacitan works in children either born small for gestational age or with Turner syndrome, Noonan syndrome or idiopathic short stature. Somapacitan is a new growth hormone medicine for treatment of low level of growth hormone. The study will last for about 3 years. During the study, the participants will be treated with somapacitan once a week. Somapacitan can be injected anytime during the day. The study doctor or nurse will show how to inject somapacitan, so that the participant knows how to do it at home.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Adverse Events (AEs) Reported in Children Born Small for Gestational Age- Weeks 0 to 26

    This outcome measure reported number of AEs in children with short stature for indication SGA. Children with SGA are born small for gestational age with insufficient catch-up growth by 2 years of age or older. An AE is any untoward medical occurrence in a clinical study participant that is temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with the use of an study treatment.

    Measured: From baseline (Week 0) to Week 26

  2. Number of Adverse Events Reported for Turner Syndrome (TS)- Weeks 0 to 26

    This outcome measure reported number of AEs in participants with short stature for indication TS. TS is a chromosomal disorder which leads to short stature. An AE is any untoward medical occurrence in a clinical study participant that is temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with the use of an study treatment.

    Measured: From baseline (Week 0) to Week 26

  3. Number of Adverse Events Reported for Noonan Syndrome- Weeks 0 to 26

    This outcome measure reported number of AEs in participants with short stature for indication NS which is a genetically heterogeneous developmental disorder characterized by postnatally reduced growth and other major disorders. An AE is any untoward medical occurrence in a clinical study participant that is temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with the use of an study treatment.

    Measured: From baseline (Week 0) to Week 26

  4. Number of Adverse Events Reported for Idiopathic Short Stature (ISS)- Weeks 0 to 26

    This outcome measure reported number of AEs in participants with short stature for indication ISS. ISS describes short children with normal GH secretion. ISS is a condition in which the height of the individual is more than 2 standard deviations below the corresponding mean height for a given age, sex and population, without evidence of systemic, endocrine, nutritional or chromosomal abnormalities. An AE is any untoward medical occurrence in a clinical study participant that is temporally associated with the use of study treatment, whether or not considered related to the study treatment. An AE can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding), symptom or disease (new or exacerbated) temporally associated with the use of an study treatment.

IGFBP-3 SDS is derived as: IGFBP - 3 SDSi = ({[IGFBP - 3 i/population median]^Skewness} - 1)/Skewness ∗ population SD; where i indicates the visit. The population median and standard deviation are the ones corresponding to the age at visit i. The score ranges from -10 (minimum) to +10 (maximum), where the greater value indicated greater IGFBP-3. The positive score indicated that the value is closer to or above the reference population compared to baseline.

    Measured: Baseline (week 0), Week 26

  26. Change in Insulin-like Growth Factor Binding Protein-3 SDS Reported for Turner Syndrome

    This outcome measure reported change in IGFBP-3 scores in children with short stature for indication TS. Change in IGFBP-3 SCS at Week 26 was derived as the IGFBP-3 SDS value at baseline Week 0 subtracted from IGFBP-3 SDS value at Week 26. IGFBP-3 SDS is derived as: IGFBP - 3 SDSi = ({[IGFBP - 3 i/population median]^Skewness} - 1)/Skewness ∗ population SD; where i indicates the visit. The population median and standard deviation are the ones corresponding to the age at visit i. The score ranges from -10 (minimum) to +10 (maximum), where the greater value indicated greater IGFBP-3. The positive score indicated that the value is closer to or above the reference population compared to baseline.

    Measured: Baseline (Week 0), Week 26

  27. Change in Insulin-like Growth Factor Binding Protein-3 SDS Reported for Noonan Syndrome

    This outcome measure reported change in IGFBP-3 scores in children with short stature for indication NS. Change in IGFBP-3 SCS at Week 26 was derived as the IGFBP-3 SDS value at baseline Week 0 subtracted from IGFBP-3 SDS value at Week 26. IGFBP-3 SDS is derived as: IGFBP - 3 SDSi = ({[IGFBP - 3 i/population median]^Skewness} - 1)/Skewness ∗ population SD; where i indicates the visit. The population median and standard deviation are the ones corresponding to the age at visit i. The score ranges from -10 (minimum) to +10 (maximum), where the greater value indicated greater IGFBP-3. The positive score indicated that the value is closer to or above the reference population compared to baseline.

    Measured: Baseline (Week 0), Week 26

  28. Change in Insulin-like Growth Factor Binding Protein-3 SDS Reported for Idiopathic Short Stature

    This outcome measure reported change in IGFBP-3 scores in children with short stature for indication ISS. Change in IGFBP-3 SCS at Week 26 was derived as the IGFBP-3 SDS value at baseline Week 0 subtracted from IGFBP-3 SDS value at Week 26. IGFBP-3 SDS is derived as: IGFBP - 3 SDSi = ({[IGFBP - 3 i/population median]^Skewness} - 1)/Skewness ∗ population SD; where i indicates the visit. The population median and standard deviation are the ones corresponding to the age at visit i. The score ranges from -10 (minimum) to +10 (maximum), where the greater value indicated greater IGFBP-3. The positive score indicated that the value is closer to or above the reference population compared to baseline.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Somapacitan in people with SGA and Turner Syndrome, run by Novo Nordisk A/S at 18 sites in 6 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 29 inclusion and 32 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 13 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in United States, Poland, South Korea, Malaysia, Netherlands and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Nov 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Adverse Events (AEs) Reported in Children Born Small for Gestational Age- Weeks 0 to 26 (time frame: From baseline (Week 0) to Week 26). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Aug 2026.
