a pilot open label clinical trial to evaluate the combined impact of two mobile health products on health outcomes in overweight adults with type 2 diabetes

Conditions: Type 2 Diabetes Mellitus

Summary: the purpose of this study is to explore the effect of 8-weeks use of the medidata patient cloud (a mobile application for capturing data directly from subjects, enabling entry of diary and quality of life data into internet-enabled devices) in combination with an activity tracker (fitbit flex) on health outcomes in overweight people with type 2 diabetes.
