Brief summary

The primary objective of the study is to determine the PK (tesamorelin) and PD (IGF-1) profiles of tesamorelin after a single 2 mg subcutaneous administration and after repeated administration once daily for 14 consecutive days. Secondary objectives include the evaluation of the safety and tolerability of tesamorelin following multiple subcutaneous injections.
