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

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.
Measured: Baseline (Week 0), Week 26

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Primary outcome
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
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.
Number of Adverse Events Reported for Turner Syndrome (TS)- Weeks 0 to 26
Time frame: From baseline (Week 0) to Week 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.
Number of Adverse Events Reported for Noonan Syndrome- Weeks 0 to 26
Time frame: From baseline (Week 0) to Week 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.
Number of Adverse Events Reported for Idiopathic Short Stature (ISS)- Weeks 0 to 26
Time frame: From baseline (Week 0) to Week 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.
