Investigating Efficacy and Safety of Once-weekly NNC0195-0092 Treatment Compared to Daily Growth Hormone Treatment (Norditropin® FlexPro®) in Growth Hormone Treatment naïve Pre-pubertal Children With Growth Hormone Deficiency

Change in height standard deviation score is presented from baseline (week 0) to end of the main trial period week 26 and end of extension trial period week 52. The formula to calculate HSDS is: HSDS = ((Height / M)\*\*L-1) / (L\*S). L: The gender and age-specific power in the Box-Cox transformation, M: The gender and age-specific median, S: The gender and age-specific generalized coefficient of variation. 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.

Change in height velocity standard deviation score is presented from baseline (week 0) to end of main trial period week 26 and end of extension trial period week 52. HVSDS was calculated using the formula: HVSDS = (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.

Adverse events per 100 patient years are presented. AEs with an onset after the first administration of trial product and up until 14 days after last trial drug administration for withdrawn participants, and with an onset after the first administration of trial product and up until visit 32 (week 364) or 14 days after last trial drug administration, which ever comes first, for all other participants, are analysed.

Participants who developed anti-NNC0195-0092 and anti-hGH antibodies are reported in this outcome measure.

Change in IGF-I SDS is presented from baseline (week 0) to end of main trial period week 26 and end of extension period week 52. 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.

Change in IGFBP-3 SDS is presented from baseline (week 0) to end of main trial period week 26 and end of extension trial period week 52. 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.

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

The bone age vs. chronological age ratio is presented at week 52. X-Ray of left hand and wrist, central assessed according to Greulich \& Pyle atlas were taken.

Serum somapacitan concentrations are presented at week 52.

Change in Treatment Related Impact Measure from baseline (week 0) to week 26 and week 52 were assessed in children with growth hormone deficiency. This outcome measure was assessed using patient reported outcome (PRO) questionnaires with 3 domains, such as emotional well-being score, physical health score, social wellbeing core and total score. The total score was calculated by taking average of each domain. The scale range for each domain and total score was from 0-100 and a lower score indicates a better health state. TRIMCGHD-O was analysed using descriptive statistics.

Total score of Treatment Burden Measure (observer) was assessed at week 26 and at week 52 in children with growth hormone deficiency. This outcome measure was assessed using PRO questionnaires. The scale range for total score was from 0-100 and a lower score indicates a better health state.

Total score of Treatment Burden Measure (parent/guardian) is reported at week 26 and at week 52 in children with growth hormone deficiency. This outcome measure was assessed using PRO questionnaires. The scale range for total score was from 0-100 and a lower score indicates a better health state.
