Trial Outcomes & Findings for Liraglutide in Obesity and Diabetes: Identification of CNS Targets Using fMRI (NCT NCT01562678)

NCT ID: NCT01562678

Last Updated: 2017-05-31

Results Overview

Effect size (region of interest z-scores, derived from z-maps of the brain) shown below is the difference in parietal cortex activation to highly desirable (high fat or high calorie, e.g. cakes, pies, fries) versus less desirable (low fat or low calorie, e.g. vegetables, fruits) food cues for each treatment condition (liraglutide or placebo) at the end of the treatment period.

PRIMARY outcome

Timeframe: 18 days of Liraglutide or placebo treatment

Population: Participants with incomplete MRI scans were excluded from the analysis.

Effect size (region of interest z-scores, derived from z-maps of the brain) shown below is the difference in parietal cortex activation to highly desirable (high fat or high calorie, e.g. cakes, pies, fries) versus less desirable (low fat or low calorie, e.g. vegetables, fruits) food cues for each treatment condition (liraglutide or placebo) at the end of the treatment period.

Outcome measures

Outcome measures
Measure
Liraglutide
n=18 Participants
Liraglutide: In the experimental phase of this randomized, placebo-controlled, cross-over, double-blinded study to assess the effects of liraglutide, subjects started the treatment with a dose of 0.6 mg for the first week, then 1.2 mg for the second week and 1.8 mg for 3 days in the third week. This sequence may have occurred for their first phase or second phase (placebo was the other phase).
Placebo
n=18 Participants
Placebo: In the placebo phase of this randomized, placebo controlled, cross-over, double-blinded study to assess the effects of liraglutide, subjects will self-inject placebo once per day for 18 days. Participants had this first or second (liraglutide was the other phase).
Change Between Highly Desirable vs. Less Desirable Food Cues in the Effect Size of Cortical Activation During Food Visualization
-0.42 z-scores of activation in cortex
Standard Error 0.27
0.53 z-scores of activation in cortex
Standard Error 0.37

7/28 • Number of events 7 • Throughout the study (4 visits in each phase of liraglutide and placebo).
There was a systematic assessment of adverse events at each visit (Days 0, 7, 14, and 17) by an MD who asked detailed medical questions and did a physical exam, plus through the use of visual analog scales administered 3 times per day where participants answered on a 10cm line questions such as "How nauseous do you feel right now?"
