Abbott Diabetes Care

Brief Summary:
This is a multi-center, prospective, non-pivotal, single arm, non-significant risk evaluation the Abbott Sensor Based Glucose Monitoring System - Pro across different stages of T2 diabetes management. This is a non-significant risk study.

Condition or disease Intervention/treatment
Type 2 Diabetes Mellitus Device: Abbott Sensor Based Glucose Monitoring System-Professional

Detailed Description:

Subjects will wear two Sensors, one applied to the back of each upper arm, for a period of 14 days. Subjects will wear the Sensor while going about their normal daily activities during the home use period. Subjects will not be able to see any glucose data. The devices will be removed at the completion of the final study visit.

Data obtained from the Reader and reports generated by the system will not be used by the subject or the research team members to determine treatment. Subjects must adhere to their diabetes clinical management plan established prior to the study.

No additional medical care will be provided to study subjects following study completion other than care related to the follow up and treatment of adverse events.

  2. Subject must have diagnosis of type 2 diabetes prior to enrollment.
  3. Subject must have been on current treatment regimen for at least 6 months prior to enrollment and must remain on therapy regimen for the duration of the study (subjects diagnosed within last 6 months must be on no medication both prior to and throughout the study to enroll).
