Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Body Weight (Amount of Change)	Changes in body wight from baseline at the final timepoint (LOCF). A linear regression model using changes in body weight from baseline at the final timepoint as the criterion variable and dose as the explanatory variable was fitted to the dataset.	Baseline, Day 7 or at the discontied of treatment	No
Secondary	Abdominal Circumference	Change in abdominal circumference from baseline (LOCF)	Baseline, Day 7 or at the discontied of treatment	No
