Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 24 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2015-04-30
• Study Completion Date: 2015-09-30

Brief Summary

The trial will investigate the accuracy and performance of a new sensor for continuous glucose monitoring (CGM), the (new generation) Enlite, CE-marked in 2013, in conjunction with the new Medtronic 640G system components.

To evaluate the accuracy and performance of the new generation Enlite sensor. This is a postmarket, interventional, open-label, non-randomized, single center clinical research trial.

The trial will adopt a prospective single-sample design using the Yellow Spring Instruments (YSI) plasma glucose reference sampling procedure in the clinic and self-monitoring of blood glucose (SMBG) plasma glucose reference sampling procedure at home.

Detailed Description

The trial will investigate the accuracy and performance (i.e. the life-time) of a new sensor for CGM, the (new generation) Enlite glucose sensor, CE-marked in 2013, in conjunction with the new Medtronic 640G system components. Accuracy and life-time of the sensor are important parameters contributing to the safety of patients and patient acceptance of this still fairly new technology.

The current trial investigates the accuracy of the new sensor in conjunction with the new 640G system components both in the clinic and at home. This enables us to assess the sensor accuracy in a well-controlled environment using a highly accurate laboratory glucose analyzer as reference as well as sensor accuracy during real-life conditions using a blood glucose meter as reference analyzer.

The data gathered in this trial will help to understand the effect of technological advancements made and can guide future development of glucose sensor for continuous glucose monitoring.

Conditions

Diabetes

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Open-label, single-sample design

The trial has an open label design with a glucose sensor intervention. Only 1 sensor system is used in the trial (no comparator).

As all subjects will receive identical devices and undergo the same experimental procedures, no randomization will be performed. Furthermore, neither subjects nor clinical staff will be blinded to the sensor readings, as knowing the sensor glucose readings will not affect the accuracy endpoint.

Group Type: OTHER

Glucose sensor (Enlite)

Intervention Type: DEVICE

This is a postmarket, interventional, open-label, non-randomized, single center clinical research trial. The trial will adopt a prospective single-sample design using the Yellow Spring Instruments (YSI) plasma glucose reference sampling procedure in the clinic and selfmonitoring of blood glucose (SMBG) plasma glucose reference sampling procedure at home. The trial will consist of 6 visits to the investigational site: a visit for informed consent procedures (Visit 0), a screening visit (Visit 1), 3 study visits (Visit 2-4) and a final examination (Visit 5).

Exclusion Criteria

• Female of childbearing potential who is pregnant, breast-feeding or intend to become pregnant or are not using adequate contraceptive methods (adequate contraceptive measures include sterilization, hormonal intrauterine devices, oral contraceptives, sexual abstinence, vasectomized partner)
• Subject has any condition that, in the opinion of the Investigator or qualified Investigational Centre staff, may preclude him/her from participating in the study and completing study related procedures.
• Subject has impaired vision or hearing problems that could compromise the handling of the device as determined by Investigator or qualified Investigational Centre staff
• Subject is unable to tolerate tape adhesive in the area of sensor placement
• Subject has any unresolved adverse skin condition in the area of sensor placement (e.g. psoriasis, rash, Staphylococcus infection)
