Primary Outcome Measures:
  • Annual Height Velocity [ Time Frame: 12 months of treatment ]
    Annual Height Velocity in cm/year measured after 12 months of treatment

Secondary Outcome Measures:
  • Height velocity at 6 months [ Time Frame: After 6 months of treatment ]
  • Change in height Standard Deviation Score (SDS) [ Time Frame: After 6 and 12 months of treatment ]
    Change in height Standard Deviation Score (compared to normal population of same age group)

  • IGF-1 serum levels [ Time Frame: Once monthly on day 4 after the last dose ]
    IGF-1 and IGFBP-3 serum levels measured once monthly on day 4 after the last dose

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Pre-pubertal child aged ≥ 3 yrs old and not above 10 years for girls or 11 years for boys with either isolated GHD, or GH insufficiency as part of multiple pituitary hormone deficiency.
  2. Confirmed diagnosis of GHD by two different GH provocation tests defined as a peak plasma GH level of ≤7 ng/ml, determined by central laboratory using a validated assay .
  3. Bone age (BA) is not older than chronological age and should be no greater than 9 years for girls and 10 years for boys.
  4. Without prior exposure to any r-hGH therapy.
  5. Normal birth size, birth weight and length for gestational age
  6. Impaired height and height velocity defined as:

    1. Height (HT) of at least 2.0 standard deviations (SD) below the mean height for chronological age (CA) and gender according to the standards from Prader et. al, 1989 , (HT SDS ≤ -2.0).
    2. Annualized height velocity (HV) below the 25th percentile for CA (HV <-0.7 SDS) and gender according to the standards of Prader et al (1989). The interval between two height measurements should be at least 6 months before inclusion.
  7. BMI must be within ±2 SD of mean BMI for the chronological age and sex according to the 2000 CDC standards.
  8. Baseline IGF-I level of at least 1 SD below the mean IGF-I level standardized for age and sex (IGF-I SDS ≤ -1.0) according to the central laboratory reference values;
  9. 12. Written informed consent of the parent or legal guardian of the patient and assent of the patient (if the patient can read).

Exclusion Criteria:

  1. Children with past or present intracranial tumor growth as confirmed by an MRI scan (with contrast).
  2. History of radiation therapy or chemotherapy.
  3. Malnourished children defined as:

    1. Serum albumin below the lower limit of normal (LLN) according to the reference ranges of central laboratory;
    2. Serum iron below the lower limit of normal (LLN) according to the reference ranges of central laboratory;
    3. BMI < -2 SD for age and sex;
  4. Children with psychosocial dwarfism.
  5. Children born small for gestational age (SGA - birth weight and/or birth length < -2 SD for gestational age).
  6. Presence of anti-hGH antibodies at screening.
  7. Any clinically significant abnormality likely to affect growth or the ability to evaluate growth, such as, but not limited to, chronic diseases like renal insufficiency, spinal cord irradiation, etc.
  8. Patients with diabetes mellitus.
  9. Patients with impaired fasting sugar (based on WHO; fasting blood sugar >110 mg/dl or 6.1 mmol/l) after repeated blood analysis.
