Overview
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.

Eligibility Criteria
Inclusion Criteria
- •Informed consent of parent or legally acceptable representative of participant and child assent, as age-appropriate must be obtained before any trial related activities
- •The parent or legally acceptable representative of the child must sign and date the Informed consent form (according to local requirements)
- •The child must sign and date child assent form or provide oral assent (if required according to local requirements)
- •Prepubertal children: a) Boys: Age more than or equal to 2 years and 26 weeks and less than or equal to 11.0 years at the time of signing informed consent.
- •Testis volume less than 4 ml. b) Girls: Age more than or equal to 2 years and 26 weeks and less than or equal to 10.0 years at the time of signing informed consent. Tanner stage 1 for breast development (no palpable glandular breast tissue)
- •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
Exclusion Criteria
- •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
Arms & Interventions
Somapacitan weekly
participants will receive once-weekly somapacitan for 52 weeks
Intervention: somapacitan
Norditropin® daily
Participants will receive Norditropin® daily for 52 weeks
Intervention: Norditropin®
Outcomes
Primary Outcomes
Height Velocity
Time Frame: Baseline (Week 0); Week 52
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).
Secondary Outcomes
- 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)
- Change in IGF-I Standard Deviation Score(Baseline (week 0), week 52)
- Change in IGFBP-3 Standard Deviation Score(Baseline (week 0), week 52)
