Scientific titleCompensatory changes in energy balance during dapagliflozin treatment in type 2 diabetes
Study acronymENERGIZE
Study objectivesThis study is designed to study the mechanisms underlying the changes in energy balance that occur with dapagliflozin treatment for type 2 diabetes (T2DM), so that in the future it might be possible to develop interventions to optimise weight loss and therefore therapeutic benefit of this agent.
