To Predict Weight Loss Response to Liraglutide (Saxenda®), From fMRI-based Determination of Food Cue Reactivity
November 30, 2023 updated by: Martin Binks, Texas Tech University
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).
