Effect of Teduglutide on Gastric Emptying in Healthy Subjects

A Randomized, Double-Blind, Placebo-Controlled, Multiple Dosing, Parallel Group Study to Assess the Effects of Teduglutide (ALX-0600) on Gastric Emptying in Healthy Subjects

The primary objective of this study is to assess the effects of 10 consecutive, daily, subcutaneous doses of 4 mg of teduglutide as compared with placebo on gastric emptying as assessed by acetaminophen absorption kinetics in healthy subjects.

4. Women who are: (1) post-menopausal; (2) surgically sterilized, OR (3) of childbearing potential with a negative pregnancy test at screening and check-in and who consent to use an acceptable method of contraception for the duration of the study and for four weeks following last dose of study drug.
