This is a 16 week, phase 4, randomized and placebo controlled trial, investigating the separate and combined effects of Sodium Glucose coTransporter 2 (SGLT2) inhibition with dapagliflozin and Glucagon Like peptide-1 (GLP-1) receptor agonism with exenatide on food intake, body weight and the neural activity in the central satiety and reward circuits in response to food-related stimuli by blood oxygen level-dependent (BOLD) fMRI in obese type 2 diabetes patients. The investigators hypothesize that treatment with SGLT2 inhibitors is associated with alterations in central reward and satiety circuits in response to food related stimuli, leading to increased appetite and food intake. In addition, the investigators hypothesize that adding a GLP-1 receptor agonist to the treatment with an SGLT2 inhibitor may increase weight loss and prevent the increased food intake during treatment with SGLT2 inhibitors due to effects on neuronal activity of central satiety and reward circuits in response to food-related stimuli in obese patients with T2DM.
The aim of this study is to investigate 1) the seperate and 2) combined actions of SGLT2 inhibition and GLP-1 receptor agonism on food intake, body weight and the activity within the central satiety and reward circuits in response to food-related stimuli and 3) wheter the combination with a GLP-1 receptor agonist can prevent the increased intake observed with SGLT2- inhibition treatment.
Methods: In four groups of obese patients with T2DM (n=16 per group), food intake and neuronal activity in relevant CNS circuits in response to food-related stimuli (using fMRI) will be investigated during 16 week treatment in a double blind placebo-controlled randomized trial with:1) SGLT2 inhibitor dapagliflozin 10 mg/day in combination with placebo GLP-1 receptor agonist exenatide twice daily, 2) GLP-1 receptor agonist exenatide twice daily in combination with placebo dapagliflozin, 3) combination of dapagliflozin 10 mg/day and exenatide twice daily, or 4) placebo dapagliflozin and placebo exenatide twice daily. To correlate changes in brain activity with subsequent feeding behavior, the investigators will measure food intake, self-reported hunger, satiety and mood, during a choice-buffet after the scanning.
Expected results: This project will gain insight into the CNS mechanisms underlying the the effects of seperate and combined treatment with SGLT2 inhibition and GLP-1 receptor agonism. Furthermore, this project will provide insight if combined treatment with a GLP-1 receptor agonist will prevent the increased intake, observed by treatment with an SGLT2 inhibitor, and if so, in the underlying (CNS) mechanisms. These findings may increase the understanding of the development of obesity and weight loss problems in obese and T2DM patients and may support the development of a balanced SGLT2 inhibitor/GLP-1 receptor agonist combination as a treatment strategy for obesity and T2DM.
