Performance Evaluation of an Advanced Algorithm With CGM in Adults, Adolescents, and Pediatrics

Study Description
Brief Summary:
The purpose of this study is to demonstrate the performance of the Guardian™ Sensor (3) with an advanced algorithm in subjects age 2 - 80 years, for the span of 170 hours (7 days).

Condition or disease Intervention/treatment Phase
Type 1 Diabetes Mellitus Type2 Diabetes Mellitus Device: Guardian™ Sensor (3) connected to a Guardian™ Connect Transmitter Not Applicable

Detailed Description:
The study is a multi-center, prospective, single-sample correlational design without controls. The purpose of this study is to demonstrate the performance of the Guardian™ Sensor (3) with an advanced algorithm in subjects age 2 - 80 years, for the span of 170 hours (7 days).

Subjects wear Guardian™ Sensor (3) and Guardian™ Connect Transmitter over 7 days and participate in FSTs. Zero calibration sensor algorithm applied to raw sensor data.
Device: Guardian™ Sensor (3) connected to a Guardian™ Connect Transmitter
Continuous Glucose Monitoring and frequent sample testing

Outcome Measures
Primary Outcome Measures :
  1. Percentage of Readings Within 20% Agreement [ Time Frame: 7 days (170 hours) ]
    Mean of daily percentage of sensor values within 20% of Yellow Springs Instrument (YSI™*) reference value (within 20 mg/dL if sensor values < 80 mg/dL), across all participants and all Frequent Sample Testing (FST) days. Note Self-Monitoring Blood Glucose (SMBG) was used for age 2-6, instead of YSI.


Eligibility Criteria

Criteria

Inclusion Criteria:

  3. Adequate venous access as assessed by investigator or appropriate staff
  4. Subjects participating in the high and low glucose challenges must have an insulin carbohydrate ratio(s) and insulin sensitivity ratio. Subjects without ratios may participate under observation only

Exclusion Criteria:

  1. Subject will not tolerate tape adhesive in the area of Guardian™ Sensor (3) placement as assessed by a qualified individual.
  2. Subject has any unresolved adverse skin condition in the area of sensor or device placement (e.g., psoriasis, rash, Staphylococcus infection)
  3. Subject is actively participating in an investigational study (drug or device) wherein they have received treatment from an investigational study (drug or device) in the last 2 weeks
  4. Subject is female and has a positive pregnancy screening test
  5. Female of child bearing age and who is sexually active should be excluded if she is not using a form of contraception deemed reliable by investigator
  6. Subject is female and plans to become pregnant during the course of the study
  7. Subject has had a hypoglycemic seizure within the past 6 months prior to enrollment
  8. Subject has had hypoglycemia resulting in loss of consciousness within the past 6 months prior to enrollment.
  9. Subject has had an episode of diabetic ketoacidosis (DKA) within the past 6 months prior to enrollment.
  10. Subject has a history of a seizure disorder
  11. Subject has central nervous system or cardiac disorder resulting in syncope
  12. Subject has a history of myocardial infarction, unstable angina, coronary artery bypass surgery, coronary artery stenting, transient ischemic attack (TIA), cerebrovascular accident (CVA), angina, congestive heart failure, ventricular rhythm disturbances or thromboembolic disease
  13. Subject has a hematocrit (Hct) lower than the normal reference range (please note that patients may use prior blood draw from routine care as long as done within 6 months of screening and report of lab placed with subject source documents)
  14. Subject has a history of adrenal insufficiency
  15. Subject is a member of the research staff involved with the study.
