Primary Outcome Measures:
  • Peak serum IGF-1 level with GH (1.4 mg/m2/day) change from baseline. [ Time Frame: Week 2 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Delta IGF-1 SDS on 0.7 & 1.4 mg GH/m2/day [ Time Frame: Baseline, week 2 ] [ Designated as safety issue: No ]
  • Delta insulin-like growth factor binding protein-3 (IGFBP-3) standard deviation score (SDS) on 0.7 & 1.4 mg GH/m2/day [ Time Frame: Baseline, week 2 ] [ Designated as safety issue: No ]
  • Delta of the ratio IGF-1:IGFBP-3 SDS on 0.7 mg & 1.4 mg GH/m2/day [ Time Frame: Baseline, week 2 ] [ Designated as safety issue: No ]
  • Delta of the ratio IGF-1:IGFBP-2 (insulin-like growth factor binding protein-2) SDS on 0.7 mg & 1.4 mg GH/m2/day [ Time Frame: Baseline, week 2 ] [ Designated as safety issue: No ]
  • Peak IGFBP-3 SDS on 0.7 mg & 1.4 mg GH/m2/day [ Time Frame: Baseline, week 2 ] [ Designated as safety issue: No ]
  • Peak of the ratio IGF-1:IGFBP-3 SDS on 0.7 mg & 1.4 mg GH/m2/day [ Time Frame: Baseline, week 2 ] [ Designated as safety issue: No ]
  • Peak of the ratio IGF-1:IGFBP-2 SDS on 0.7 mg & 1.4 mg GH/m2/day [ Time Frame: Baseline, week 2 ] [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: March 2013
Estimated Study Completion Date: November 2015
Estimated Primary Completion Date: November 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: NutropinAq Drug: Nutropin [Somatropin (rDNA origin) for injection]
Doses in the diagnostic protocol are 0.7 and 1.4 mg/m2/day, injected by subcutaneous injection at bedtime for 2 weeks, divided by washout periods of preferably 4 weeks (accepted range 4-6 weeks). An additional period of 2 weeks on 2.8 mg/m2/day (after a washout period of 4-6 weeks) will be added if the IGF-I response on either dosage is insufficient (serum IGF-I SDS <0).

  Eligibility

Ages Eligible for Study:   2 Years to 10 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Age 2.0 - 9.0 years for females, 2.0 - 10.0 yrs for males.
  • Prepubertal stage (Tanner 1 for breast (B1) in females, or Tanner 1 for genitals (G1) for males).
  • Bone age < 10 'years' (males) or < 9 'years' (females) according to Greulich and Pyle. The bone age will be read by the pediatric endocrinologist responsible for the pre-study screening visit.
  • Height SDS < -2.5 for ethnically adequate references. For children of Dutch or Western European origin the 1997 nation-wide references for Dutch children will be used. For children of Moroccan or Turkish origin, the respective reference charts will be used. For children of other ethnicities, the 1977 North American (NCHS/WHO) reference will be used, as these charts have been accepted by WHO as world-wide standard from the age of 5 years.

Exclusion Criteria:

  • Has a history of hypersensitivity to growth hormone or phenol (conservative added to GH in NutropinAq), or drugs with a similar chemical structure.
  • Has abnormal baseline findings, any other medical condition(s) or laboratory findings that, in the opinion of the Investigator, might jeopardise the subject's safety or decrease the chance of obtaining satisfactory data needed to achieve the objective(s) of the study.
  • Has a birth weight and/or length below -2 SDS for Swedish reference charts. Patients will not be excluded due to an unknown birth weight or length.
  • Has a known cause of short stature, or any significant concomitant disease that is likely to interfere with growth or with the study schedule/objectives, or is a known contraindication to GH treatment.
