    Recruitment
    Recruitment details
    This randomized controlled trial enrolled small for gestational age (SGA) children at 16 centers in 8 countries. In total, 52 subjects were screened for the study, of these, 9 subjects were considered screen failures. The remaining 43 subjects were randomized to receive either study drug (Genotropin) or were not treated (Control).

    Pre-assignment
    Screening details
    Subjects aged between 19 to 29 months at Screening visit, born SGA (birth length and/or weight less than (<) 2 standard deviations (SD) for gestational age, using country specific standards), height below -2.5 SD at Screening (19-29 months of age),and had at least one measurement of length between 12 and 18 months of age were enrolled in this study

    Arm description
    Subjects received Genotropin at a dose of 0.035 mg/kg/d for 24 months. The dose was calculated based on the actual body weight, and the closest dosing step of the 5 mg pen used. The starting dose for the first 2 weeks was 1/3 of the calculated dose. After 2 weeks the dose was increased to 2/3 of the calculated dose. After 4 weeks the daily dose was the dose calculated on body weight at randomization.

    Change From Baseline in Height Standard Deviation Score (SDS) at Month 24
    End point description
    Height SDS was calculated at the relevant visit by means of the following formula:Height SDS=(subject height)-(normal height)/normal height standard deviation. Where subject height refers to the subject’s height at the relevant visit, and normal height and the normal height standard deviation equals the population mean and standard deviation values for subjects of a similar age and gender. The change from Baseline value for height SDS was calculated as the difference between the parameter values at a specific visit, and the Baseline parameter values. The scores were centred around 0. Negative score indicated a subject was smaller for their age/gender.Full Analysis Set (FAS) included subjects who were randomized to treatment and completed at least 1 post-baseline efficacy measure. Missing values were imputed using LOCF method. One subject was randomized to Genotropin but did not receive any treatment. This subject was excluded from FAS but included in Control for safety analysis.

    Change From Baseline in Mental Development Using the Mental Development Index (MDI) of Bayley Scale at Month 12
    End point description
    The Bayley Scale of Infant Development (BSID-II) measured the mental and motor development and test behavior of subjects from 1 to 42 months of age. The scale was used to describe the current developmental functioning of infants and to assist in diagnosis and treatment planning for infants with developmental delays or disabilities. The BSID-II provided the mental raw score which was used to calculate the MDI score. Possible MDI scores ranged from 50-150. The MDI score of 69 and below indicated significantly delayed performance, 70 to 84 indicated mildly delayed performance, 85 to 114 indicated normal limit, and 115 and above indicated accelerated performance. FAS included subjects who were randomized to treatment and completed at least one post-baseline efficacy measure. One subject was randomized to Genotropin but did not receive any treatment. This subject was excluded from FAS but included in control group for safety analysis.

    Change From Baseline in Head Circumference SDS at Months 3, 6, 12, 18 and 24
    End point description
    Head circumference SDS was calculated by means of the following formula = (Subject head circumference)-(Normal head circumference)/Normal head circumference standard deviation. Where subject head circumference refers to the subject's head circumference at the relevant visit, and normal head circumference and the normal head circumference standard deviation equals the population mean and standard deviation values for subjects of a similar age and gender. FAS included subjects who were randomized to treatment and completed at least one post-baseline efficacy measure. One subject was randomized to Genotropin® but did not receive any treatment. This subject was excluded from FAS but included in Control group for safety analysis.

    Change From Baseline in Body Weight at Months 3, 6, 12, 18, and 24
    End point description
    Body weight was measured at all the relevant visits. The change from Baseline in body weight was calculated as the difference between the parameter values at each visit, and the Baseline parameter values. FAS included subjects who were randomized to treatment and completed at least one post-baseline efficacy measure. One subject was randomized to Genotropin but did not receive any treatment.

    Genotropin
    Reporting group description
    Subjects received Genotropin at a dose of 0.035 mg/kg/d for 24 months. The dose was calculated based on the actual body weight, and the closest dosing step of the 5 mg pen used. The starting dose for the first 2 weeks was 1/3 of the calculated dose. After 2 weeks the dose was increased to 2/3 of the calculated dose. After 4 weeks the daily dose was the dose calculated on body weight at randomization.
