Brief Summary

The study compares two medicines for children with a low level of hormone to grow: somapacitan (a new medicine) given once a week and Norditropin® (a medicine doctors can already prescribe) given once a day. Researchers will test somapacitan to see how well it works, compared to the standard treatment with Norditropin®. The participants will either get Norditropin® once every day or somapacitan once every week - which treatment the participant gets is decided by chance. The participant and the study doctor will know which treatment the participant gets. The study includes a 52 week treatment period and a minimum of 30 days follow up period.

Conditions

Growth Hormone Deficiency in Children

Outcome Measures

Primary Outcomes (1)

• Height Velocity

  Height velocity (HV) was derived from height measurements taken at baseline (week 0) and the week 52 visit as: HV = (height at 52 weeks visit - height at baseline)/(time from baseline to 52 weeks visit in years).

  Baseline (Week 0); Week 52

Secondary Outcomes (7)

• Change in Bone Age

  Week -2, week 52

• Change in Height Standard Deviation Score

  Baseline (week 0), week 52

• Change in Height Velocity Standard Deviation Score

  Baseline (week 0), week 52

• Change in Fasting Plasma Glucose

  Baseline (week 0), week 52

• Change in HbA1c

  Baseline (week 0), week 52

Study Arms (2)

Somapacitan weekly

EXPERIMENTAL

participants will receive once-weekly somapacitan for 52 weeks

Drug: somapacitan

Norditropin® daily

ACTIVE COMPARATOR

Participants will receive Norditropin® daily for 52 weeks

Drug: Norditropin®

Interventions

somapacitan DRUG

Somapacitan (0.16 mg/kg/week) will be administered subcutaneously (s.c.; under the skin) once weekly by PDS290 pen-injector. Somapacitan can be injected any time during the once weekly dosing day. The dose will be calculated based on the subject's current body weight.

Somapacitan weekly

Norditropin® DRUG

Norditropin® (0.034 mg/kg/day) will be administered s.c. once daily by FlexPro® pen-injector. Norditropin® should be injected daily in the evening. The dose will be calculated based on the subject's current body weight.

Norditropin® daily

• Confirmed diagnosis of growth hormone deficiency determined by two different growth hormone stimulation tests performed within 12 months prior to randomisation, defined as a peak growth hormone level of less than or equal to 10.0 ng/ml using the WHO International Somatropin 98/574 standard
• If only one growth hormone stimulation test is available before screening, then confirmation of growth hormone deficiency by second and different growth hormone stimulation test must be done
• For children with at least 2 additional pituitary hormone deficiencies (other than growth hormone deficiency) only one growth hormone stimulation test is needed
• Impaired height defined as at least 2.0 standard deviations below the mean height for chronological age and gender according to Chinese general population standards at screening
• Impaired height velocity defined as annualised height velocity at screening less than 7cm/year for subjects between 2.5 and 3 years old and less than 5 cm/year for subjects from 3 years and above calculated over a time span of minimum 3 months and maximum 18 months prior to screening according to Chinese guideline and expert consensus on children with short stature and GH therapy
• No prior exposure to growth hormone therapy or IGF-I treatment
• Bone age less than chronological age at screening

• IGF-I \< -1.0 SDS at screening, compared to age and gender normalized range measured at central laboratory
• No intracranial tumour confirmed by magnetic resonance imaging or computer tomography scan. An image or scan taken within 9 months prior to screening can be used as screening data if the medical evaluation and conclusion is available

You may not qualify if:

• Known or suspected hypersensitivity to trial product(s) or related products.
• Previous participation in this trial. Participation is defined as randomisation.
• Receipt of any investigational medicinal product within 3 months before screening or participation in another clinical trial before randomisation
• Any known or suspected clinically significant abnormality likely to affect growth or the ability to evaluate growth with standing height measurements:
• Turner Syndrome (including mosaicisms)
• Chromosomal aneuploidy and significant gene mutations causing medical "syndromes" with short stature, including but not limited to Laron syndrome, Noonan syndrome, Prader-Willi Syndrome, abnormal SHOX-1 gene analysis or absence of GH receptors
• Significant spinal abnormalities including but not limited to scoliosis, kyphosis and spina bifida variants
• Congenital abnormalities (causing skeletal abnormalities), including but not limited to Russell-Silver Syndrome or skeletal dysplasias
• Family history of skeletal dysplasia
• Children born small for gestational age (birth weight 10th percentile of the recommended gender-specific birth weight for gestational age according to national standards in China5
• Children diagnosed with diabetes mellitus or screening values from central laboratory of
• fasting plasma glucose more than or equal to 126 mg/dl (7.0 mmol/L) or
• HbA1c more than 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
• Children requiring inhaled glucocorticoid therapy at a dose greater than 400 µg/day of inhaled budesonide or equivalents for longer than 4 consecutive weeks within the last 12 months prior to screening
