Summary
Brief summary
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.
