  • Human growth hormone conjugated with biocompatible polymer
    Publication number: 20060134736
    Abstract: The present invention relates to conjugates of biocompatible polymers and hGH, particularly PEG-hGH, where the activated biocompatible polymer is conjugated to a carboxyl group of hGH at a molar ratio of 2:1 or less, preferably 1:1, methods of preparation, and related pharmaceutical compositions. The PEG-hGH conjugates have up to 20% of the activity of the native hGH while the in vivo half life is increased 10 fold. The PEG-hGH conjugates may be used therapeutically to treat growth retardation or growth failure, especially short stature in children, and conditions related to aging.
