Study summary

The study compares 2 medicines used for the treatment of children who are born small and who stayed small: somapacitan given once a week (a new medicine) and Norditropin® given once a day (the medicine doctors can already prescribe).

Participants will either get somapacitan or Norditropin® - which treatment is decided by chance. Both participants and the study doctor will know which treatment the participants get. The study will last for 5 years. Participants will take either an injection once every week or once every day.

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. Height Velocity

    Height velocity (HV) was derived from height measurements taken at baseline (week 0) and week 26 visit as: HV = (height at 26 weeks visit - height at baseline)/(time from baseline to 26 weeks visit in years). The outcome measure was evaluated based on the data from in-trial observation period. In-trial observation period: from first administration and up until week 26 or last trial contact, whichever came first.

    Time frame: Baseline (week 0); week 26

Secondary outcomes

  1. Change in Ratio of Bone Age Versus Chronological Age

    Change in ratio of bone age (years) versus chronological age (years) from baseline (week 0) to week 52 is presented. X-rays of left hand and wrist for bone age assessment according to the Greulich and Pyle atlas were taken. X-ray images were sent to a central imaging laboratory for evaluation. Chronological Age (years) was calculated as: (Date minus Date of Birth) divided by 365.25. The outcome measure was evaluated based on the data from in-trial observation period. In-trial observation period: from first administration and up until week 52 or last trial contact, whichever came first.

    Time frame: Baseline (week 0); week 52

  2. Change in Height Standard Deviation Score (HSDS)

    Change in HSDS from baseline (week 0) to week 26 is presented. HSDS was derived using Centre for Disease Control and Prevention (CDC) standards. HSDS = \[(height/population median)\^skewness - 1\]/(skewness \* population standard deviation) where skewness, median and standard deviation is given by a reference growth table for the corresponding chronological age. The range for HSDS was -10 to +10. Negative scores indicated a height below the mean height for a child with the same age and gender, whereas positive scores indicated a height above the mean height for a child with the same age and gender. Positive value in change from baseline in HSDS indicated that HSDS was better than baseline HSDS In-trial observation period: from first administration and up until week 26 or last trial contact, whichever came first.

    Time frame: Baseline (week 0); week 26

  3. Change in Height Velocity Standard Deviation Score (HVSDS)

    Change in HVSDS from baseline (week 0) to week 26 is presented. HVSDS was derived using Prader standards. HV SDS was calculated using the formula: HV SDS = (height velocity - mean)/standard deviation (SD), where height velocity was the height velocity variable measured, mean and SD of height velocity by gender and age for the reference population. The range for HVSDS was -10 to +10. Negative scores indicated a height velocity below the mean height velocity for a child with the same age and gender, whereas positive scores indicated a height velocity above the mean height velocity for a child with the same age and gender. Positive value in change from baseline in HVSDS indicated that HVSDS was better than baseline HVSDS. The outcome measure was evaluated based on the data from in-trial observation period. In-trial observation period: from first administration and up until week 26 or last trial contact, whichever came first.

    Time frame: Baseline (week 0); week 26

  4. Change in Fasting Plasma Glucose

    Change in fasting plasma glucose from baseline (week 0) to week 26 is presented. The outcome measure was evaluated based on the data from on-treatment observation period. On-treatment observation period: from first administration and up until last trial contact, week 26 or 14 days after last administration, whichever came first.

    Time frame: Baseline (week 0); week 26

  5. Change in Homeostatic Model Assessment for Steady State Beta Cell Function (HOMA-B)

    Change in HOMA-B from baseline (week 0) to week 26 is presented. HOMA-B is a measure of the beta cell function and was calculated as follows: HOMA-B = (20 \* fasting insulin (picomoles per liter \[pmol/L\]) \* 1/6(microunit per milliliter \[µU/mL\]))/ FPG(mmol/L)-3.5). HOMA-beta score ranges from minus infinity to infinity (no limits). Higher score means better beta-cell function for HOMA-beta. Negative change from baseline (week 0) in HOMA-B indicated a worse outcome. The outcome measure was evaluated based on the data from on-treatment observation period. On-treatment observation period: from first administration and up until last trial contact, week 26 or 14 days after last administration, whichever came first.

    Time frame: Baseline (week 0); week 26

  6. Change in Homeostatic Model Assessment for Insulin Resistance (HOMA-IR)

    Change in HOMA-IR from baseline (week 0) to week 26 is presented. Insulin resistance is a condition in which cells fail to respond to normal actions of hormone in body. HOMA-IR is calculated using a participant's fasting plasma insulin and glucose levels. HOMA-IR = fasting serum insulin (micro international units per milliliter (μU/ml)) × fasting plasma glucose (millimoles per liter (mmol/l)) / 22.5. HOMA-IR scores are classified as follows: less than 1.0: considered insulin sensitive, 0.5-1.4: considered healthy, above 1.8: considered early insulin resistance; above 2.7 is considered significant insulin resistance. HOMA-IR score ranges from 0-infinity (no upper limit). Higher the score, higher the level of insulin resistance. The outcome measure was evaluated based on the data from on-treatment observation period. On-treatment observation period: from first administration and up until last trial contact, week 26 or 14 days after last administration, whichever came first.

    Time frame: Baseline (week 0); week 26

  7. Change in Glycated Haemoglobin (HbA1c)

    Change in HbA1c from baseline (week 0) to week 26 is presented. The outcome measure was evaluated based on the data from on-treatment observation period. On-treatment observation period: from first administration and up until last trial contact, week 26 or 14 days after last administration, whichever came first.

    Time frame: Baseline (week 0); week 26

  8. Change in Insulin-like Growth Factor I (IGF-I) Standard Deviation Score (SDS)

    Change in IGF-I SDS from baseline (week 0) to week 26 is presented. IGF-I SDS was provided by the central laboratory; its calculation is based on the actual value of IGF-1 minus mean reference value of IGF-1 divided by reference standard deviation of IGF-1. The range for IGF-I SDS was from -10 to +10. Negative scores indicated a IGF-I below the mean IGF-I for a child with the same age and gender, whereas positive scores indicated a IGF-I above the mean IGF-I for a child with the same age and gender. Positive value in change from baseline in IGF-I SDS indicated that IGF-I SDS was higher than baseline IGF-I SDS. The outcome measure was evaluated based on the data from on-treatment observation period. On-treatment observation period: from first administration and up until last trial contact, week 26 or 14 days after last administration, whichever came first.

    Time frame: Baseline (week 0); week 26

  9. Change in Insulin-like Growth Factor Binding Protein 3 (IGFBP-3) SDS

    Change in IGFBP-3 SDS from baseline (week 0) to week 26 is presented. The range for IGFBP-3 SDS was from -10 to +10. Negative scores indicated a IGFBP-3 below the mean IGFBP-3 for a child with the same age and gender, whereas positive scores indicated a IGFBP-3 above the mean IGFBP-3 for a child with the same age and gender. Positive value in change from baseline in IGFBP-3 SDS indicated that IGFBP-3 SDS was higher than baseline IGFBP-3 SDS.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
