Safety Study of Syntropin (Human Growth Hormone) for the Treatment of Growth Hormone Deficiency
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this study is to evaluate the pharmacokinetics of Syntropin (a human growth hormone) and to determine the serum concentration of IGF-1 after Syntropin injection.
Condition or disease
Growth Hormone Deficiency
Syntropin will be administered by subcutaneous injection. Eligible patients will receive a subcutaneous injection of octreodite (to suppress endogenous growth hormone secretion) 12 hours before, immediately prior to, and 12 hours after the scheduled injection of growth hormone.
