研究概览
简要总结
A 52 week trial of TransCon hGH, a long-acting growth hormone product, versus human growth hormone therapy. TransCon hGH will be given once-a-week, human growth hormone (hGH) will be given daily. Approximately 150 prepubertal, hGH-treatment naïve children (males and females) with GHD will be included. Randomization will occur in a 2:1 ratio (TransCon hGH : Genotropin). This is a global trial that will be conducted in Armenia, Australia, Belarus, Bulgaria, Georgia, Greece, Italy, New Zealand, Poland, Romania, Russia, Turkey, Ukraine, and the United States.

入选标准
- •Prepubertal children with GHD (either isolated or as part of a multiple pituitary hormone deficiency) in Tanner stage 1 (Tanner 1982) aged:
- •Boys: 3-12 years, inclusive
- •Girls: 3-11 years, inclusive
- •Impaired height (HT) defined as at least 2.0 standard deviations (SD) below the mean height for chronological age and sex (HT SDS ≤ -2.0) according to the 2000 CDC Growth Charts for the United States Methods and Development, available at http://www.cdc.gov/growthcharts/
- •Diagnosis of GHD confirmed by 2 different GH stimulation tests, defined as a peak GH level of ≤10 ng/mL, determined with a validated assay
- •Bone age (BA) at least 6 months less than chronological age
- •Baseline IGF-1 level of at least 1 SD below the mean IGF-1 level standardized for age and sex (IGF-1 SDS ≤-1)

- •History or presence of malignant disease; any evidence of present tumor growth
- •Closed epiphyses
- •Major medical conditions and/or presence of contraindication to hGH treatment
- •Participation in any other trial of an investigational agent within 3 months prior to Screening
