Feasibility Study to Assess the Safety and Functionality of the GluSense Continuous Glucose Monitor in Diabetic Patients

Currently marketed CGM sensors have an approved functional lifetime of up to 1 week. Pre-clinical studies have demonstrated that GluSense-LTone 2e3 sensors may be used to accurately monitor glucose levels for 30 days. The purpose of this study is to assess the safety and functionality of the device in human patients for consecutive 15 days.

GluSense-LTone 2e3 as long term CGM, will require less sensor replacements and calibration, meaning less patient interventions, and is therefore will be much more user friendly. Moreover, GluSense-LTone 2e3 shows potentially increased accuracy, especially in the critically important hypoglycemic range, meaning that better management of patient's condition may be attained.

GluSense-LTone 2e3 is a continuous glucose monitoring (CGM) system. It is a semi-invasive, optical fiber-based device with a lifetime of up to one month. The purpose of this study is to assess the safety, accuracy, calibration requirements and effective lifetime of the device.

Inclusion Criteria:

Patients must meet all of the following inclusion criteria to be eligible for participation in this study:

• Male or female patients between 18 and 50 years of age
• Patients with type 1 diabetes mellitus.
• The ability to read, understand and sign an informed consent form. Written consent must be obtained prior to initiation of study procedures

Exclusion Criteria:

Patients who meet any of the following exclusion criteria are not to be enrolled in this study:

• Clinical significant illness that can compromise patient's health during study such as:

  • Significant current heart disease
  • Significant Liver or kidney disease
  • HIV infection
  • Hepatitis B or Hepatitis C infection
  • Malignancy
  • Major allergic skin disease including plaster allergies
