E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Cohort I:
To evaluate the efficacy of multiple dose regimens of once-weekly NNC0195-0092 after 26 weeks of treatment in GH treatment naïve pre-pubertal children with GHD compared to once-daily hGH administration (Norditropin® FlexPro®).
Cohort II and III:
To evaluate the safety of once-weekly NNC0195-0092 during at least 13 weeks and up to 208 weeks of treatment in children with GHD. |
|
E.2.2 | Secondary objectives of the trial |
Cohort I:
• To evaluate the safety of multiple dose regimens of once-weekly NNC0195-0092 during 26 weeks of treatment in GH treatment naïve prepubertal children with GHD.
• To evaluate the efficacy and safety of multiple dose regimens of once-weekly NNC0195- 0092 for up to 364 weeks of treatment in GH treatment naïve pre-pubertal children with GHD compared to Norditropin® FlexPro®.
• To investigate the impact of NNC0195-0092 relative to Norditropin® FlexPro® on wellbeing, psychosocial functioning and treatment satisfaction in GH treatment naïve prepubertal children with GHD.
• To monitor NNC0195-0092 and Norditropin® PK throughout the trial. |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Cohort I:
• Pre-pubertal children
- Boys: Tanner stage 1 for pubic hair and testis volume < 4 ml, age ≥ 2 years and 26 weeks and ≤ 10.0 years at screening
- Girls: Tanner stage 1 for breast development (no palpable glandular breast tissue) and pubic hair, age ≥ 2 years and 26 weeks and ≤ 9.0 years at screening
• Confirmed diagnosis of GHD within 12 months prior to screening as determined by two different GH stimulation tests, defined as a peak GH level of ≤7.0 ng/ml. For children with three or more pituitary hormone deficiencies only one GH stimulation test is needed.
• No prior exposure to GH therapy and/or IGF-I (insulin-like growth factor I) treatment.
• Height of at least 2.0 standard deviations below the mean height for chronological age (CA) and gender according to the standards of Centers for Disease Control and Prevention 2-20 years: Girls/Boys stature-for-age and weight-for-age percentiles CDC at screening.
• Annualized height velocity (HV) at screening below the 25th percentile for CA and gender or below -0.7 SD score for CA and sex, according to the standards of Prader calculated over a time span of minimum 6 months and maximum 18 months prior to screening.
Cohort II:
- < 2 years and 26 weeks and a minimum weight of 5 kg at screening.
- Confirmed diagnosis of GHD, the GHD diagnosis must be confirmed by investigator according to local practice.
- For GH treatment naïve subjects, no prior exposure to GH therapy and/or IGF-I treatment.
- For GH treatment naïve subjects, IGF-I SDS < -1.0 at screening, compared to age and sex normalized range according to central laboratory measurements.
Cohort III:
Age:
- Girls: > 9 years and ≤ 17 years at screening.
- Boys: > 10 years and ≤ 17 years at screening.
- Confirmed diagnosis of GHD:
a) for GH treatment naïve subjects, confirmed diagnosis within 12 months prior to screening as determined by two different GH stimulation tests, defined as a peak GH level of ≤ 7.0 ng/ml. For children with three or more pituitary hormone deficiencies only one GH stimulation test is needed.
b) for non-GH treatment naïve subjects, confirmed GHD diagnosis by investigator according to local practice
- For GH treatment naïve subjects, no prior exposure to GH therapy and/or IGF-I treatment.
- Open epiphyses; defined as bone age < 14 years for females and bone age < 16 years for males. |
|
E.4 | Principal exclusion criteria |
Cohort I, II and III:
• Any clinically significant abnormality likely to affect growth or the ability to evaluate growth with standing/length measurements:
- Chromosomal aneuploidy and significant gene mutations causing medical "syndromes" with short stature, including but not limited to Turner syndrome, Laron syndrome, Noonan syndrome, or absence of GH receptors.
- Congenital abnormalities (causing skeletal abnormalities), including but not limited to Russell-Silver Syndrome, skeletal dysplasias.
- Significant spinal abnormalities including but not limited to scoliosis, kyphosis and spina bifida variants.
• Children born small for gestational age (SGA - birth weight and/or birth length < -2 SD for gestational age).
• Concomitant administration of other treatments that may have an effect on growth (not applicable to non-GH treatment naïve subjects in cohort II and III), including but not limited to methylphenidate for treatment of attention deficit hyperactivity disorder (ADHD).
• Prior history or presence of malignancy and/or intracranial tumour. |
