E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To demonstrate that one daily dose of ZOMACTON (10 mg/mL) is equivalent to one daily dose of GENOTROPIN (12 mg/mL) in terms of growth measured as height velocity based on 12 months of treatment. |
|
E.2.2 | Secondary objectives of the trial |
1. To investigate the efficacy of one daily dose of ZOMACTON compared with one daily dose of GENOTROPIN measured as an increase in height SDS during 12 months of treatment.
2. To investigate the efficacy of one daily dose of ZOMACTON compared with one daily dose of GENOTROPIN measured as an increase in height velocity SDS during 12 months of treatment.
3. To investigate the effect of ZOMACTON versus GENOTROPIN on the serum levels of IGF-1 and IGFBP-3 during 12 months as compared to baseline.
4.To investigate the Δbone age (ΔBA) at 12 months as compared to baseline for ZOMACTON versus GENOTROPIN.
5.To investigate the safety of treatment of ZOMACTON as compared to GENOTROPIN (safety lab, frequency and severity of adverse events, immunogenicity) |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Inclusion criteria Pre-screening: 1.Signed informed consent and obtained assent. 2.Children aged ≥ 3 years and not above 10 years for girls or 11 years for boys at the Pre-screening visit. 3.A positive locally performed GH stimulation test (defined as peak plasma level of < 9 ng/mL or lower if so required by the country specific board(s)) prior to the Pre-screening visit. 4.Height SDS < -2 SD of reference value for chronological age (CA) 5.Height velocity SDSCA ≤ 0 SD of reference value for at least 6 months prior to the Pre-screening visit 6.Height recorded for at least 6 months but performed no more than 18 months before the Pre-screening visit.
Inclusion criteria Screening: 7.Reconfirmed signed informed consent and obtained assent 8.The difference between CA-BA ≥ 1. 9.Idiopathic GH deficiency confirmed during the Pre-screening period by a standard GH stimulation test (defined as peak plasma level of < 9 ng/mL or lower if so required by the country specific board(s))
