The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
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.
