Clinical Trial Summary

The study is a single center, randomized, double blind, placebo controlled; parallel-group repeated measures design. Subjects will be randomly assigned to either Saxenda® or placebo group after baseline assessments. The study will consist of a 4-week partial dose period (Liraglutide 0.6mg, 1.2mg, 1.8mg, 2.4 mg) and a 12-week full-dose (Liraglutide 3.0 mg) period. The placebo group will administer equivalent volumes of the pre-filled solutions from pen-injector at the same time, using the same method during this period. The study proposes to identify factors contributing to early weight loss response in a Saxenda® treatment program. Specifically, the proposed experiments will help determine if Saxenda® changes brain functional Magnetic Resonance Imaging Food Cue Reactivity (fMRI-FCR) and whether the magnitude of that change is associated with changes in behavioral and physiological variables (hunger, satiety, cravings and weight loss).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Compare the changes of pre-prandial fMRI-FCR in Liraglutide 3.0 vs. Placebo Group	Pre-prandial fMRI-FCR will be measured via fMRI	Baseline, Week 4, and Week 16
Primary	Compare the changes of post-prandial fMRI-FCR in Liraglutide 3.0 vs. Placebo Group	Post-prandial fMRI-FCR will be measured via fMRI	Baseline, Week 4, and Week 16
Primary	Compare the changes of energy intake in Liraglutide 3.0 vs. Placebo Group	Energy intake will be assessed via ad libitum feeding	Baseline, Week 4, and Week 16
Primary	Compare the changes of hunger/satiety in Liraglutide 3.0 vs. Placebo Group	Hunger/satiety will be assessed via Visual Analog Scale (VAS).
