Primary Outcome Measures:
  • Change From Baseline in Height Standard Deviation Score (SDS) at Month 24. [ Time Frame: Baseline and Month 24 ] [ Designated as safety issue: No ]
    Height SDS was calculated at the relevant visit by means of the following formula: Height SDS = (participant height) - (normal height)/normal height standard deviation. Where participant height refers to the participant's height at the relevant visit, and normal height and the normal height standard deviation equals the population mean and standard deviation values for participants 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.


Secondary Outcome Measures:
  • Change From Baseline in Growth Velocity SDS at Month 24. [ Time Frame: Baseline and Month 24 ] [ Designated as safety issue: No ]
    The growth velocity SDS was calculated at the relevant visit by means of the following formula: Growth velocity SDS = (participant growth velocity) - (normal growth velocity)/normal growth velocity standard deviation. Where, participant growth velocity refers to the participant's growth velocity at the relevant visit, and normal growth velocity and the normal growth velocity standard deviation equals the population mean and standard deviation values for participants of a similar age and gender. The change from Baseline value for growth velocity SDS was calculated as the difference between the parameter values at a specific visit, and the Baseline parameter values.

  • Change From Baseline in Height SDS at Month 12. [ Time Frame: Baseline and Month 12 ] [ Designated as safety issue: No ]
    Height SDS was calculated at the relevant visit by means of the following formula: Height SDS = (participant height) - (normal height)/normal height standard deviation. Where participant height refers to the participant's height at the relevant visit, and normal height and the normal height standard deviation equals the population mean and standard deviation values for participants 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.

  • Change From Baseline in Growth Velocity SDS at Month 12. [ Time Frame: Baseline and Month 12 ] [ Designated as safety issue: No ]
    The growth velocity SDS was calculated at the relevant visit by means of the following formula: Growth velocity SDS = (participant growth velocity) - (normal growth velocity)/normal growth velocity standard deviation. Where, participant growth velocity refers to the participant's growth velocity at the relevant visit, and normal growth velocity and the normal growth velocity standard deviation equals the population mean and standard deviation values for participants of a similar age and gender. The change from Baseline value for growth velocity SDS was calculated as the difference between the parameter values at a specific visit, and the Baseline parameter values.

  • Change From Baseline in Mental Development Using the Mental Development Index (MDI) of Bayley Scale at Month 12. [ Time Frame: Baseline and Month 12 ] [ Designated as safety issue: No ]
    The Bayley Scale of Infant Development (BSID-II) measured the mental and motor development and test behavior of participants 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. 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.

  • Change From Baseline in Psychomotor Development Using the Psychomotor Development Index (PDI) of Bayley Scale at Month 12. [ Time Frame: Baseline and Month 12 ] [ Designated as safety issue: No ]
    BSID-II measured the mental and motor development and test behavior of participants 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 psychomotor raw score which was used to calculate the PDI. The PDI 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.

  • Head Circumference SDS at Months 3, 6, 12, 18 and 24. [ Time Frame: Months 3, 6, 12, 18 and 24 ] [ Designated as safety issue: No ]
    Head circumference SDS was calculated by means of the following formula = (Participant head circumference)-(Normal head circumference)/ Normal head circumference standard deviation. Where participant head circumference refers to the participant'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 participants of a similar age and gender.

  • Change From Baseline in Head Circumference SDS at Months 3, 6, 12, 18 and 24. [ Time Frame: Baseline, Months 3, 6, 12, 18 and 24. ] [ Designated as safety issue: No ]
    Head circumference SDS was calculated by means of the following formula = (Participant head circumference)-(Normal head circumference)/Normal head circumference standard deviation. Where participant head circumference refers to the participant'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 participants of a similar age and gender.

  • Change From Baseline in Body Weight at Months 3, 6, 12, 18, and 24. [ Time Frame: Baseline, Months 3, 6, 12, 18, and 24 ] [ Designated as safety issue: No ]
    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.

  • Change From Baseline in Body Mass Index (BMI) at Months 3, 6, 12, 18, and 24. [ Time Frame: Baseline, Months 3, 6, 12, 18, and 24 ] [ Designated as safety issue: No ]
    Body mass index was calculated for all visits by means of the following formula: BMI (kg/m2) = Weight (kg)/(Height[m])2. The change from Baseline BMI was calculated as the difference between the parameter values at each visit, and the Baseline parameter values.
