Study information
Scientific title
Compensatory changes in energy balance during dapagliflozin treatment in type 2 diabetes
Acronym
ENERGIZE
Study hypothesis
This 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.

Target number of participants
Planned Sample Size: 52; UK Sample Size: 52; Description: primary outcome measure is energy intake(g) after 12weeks.52 subjects are required in order to detect a 12.5% change with 80% power and at a two-sided 5% level of significance using the method for a paired t-test.This estimate assumes a correlation between measurements of 0.7 and a between-subject standard deviation of 165.The change in energy intake of 12.5% is based on a baseline level of 460g.This allows for a drop-out rate of 20% and was calculated using PROC POWER in SAS 9.3
