Outcome Measures

Primary Outcomes (1)

  • Harmony 1 Sensor accuracy

    Sensor accuracy will be evaluated compared to YSI plasma glucose values during frequent sample testing. A within 30% mean agreement rate (±22.5 mg/dL when Reference BG ≤ 75 mg/dL) between sensor and YSI will be evaluated against the null Hypothesis for varying glucose ranges.

    10 days

Study Arms (1)

Group A

OTHER

Subjects wearing Harmony 1 Sensor for up to 10 days.

Device: Harmony 1 Sensor

Interventions

Use of Harmony 1 Sensor over 10 days in arm and abdomen and used with the Guardian Mobile App in subjects aged 2-75 years who have had a diagnosis of type 1 or type 2 diabetes for at least one year.

Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Subject is 2-75 years of age at time of screening
  • A clinical diagnosis of type 1 or 2 diabetes for a minimum of 12 months duration as determined via medical record or source documentation by an individual qualified to make a medical diagnosis
  • Adequate venous access as assessed by investigator or appropriate staff
  • Subjects participating in the high and low glucose challenges must have an established insulin carbohydrate ratio(s) and insulin sensitivity ratio. (The term "established" refers to a ratio that has been previously defined and tested prior to screening visit). Subjects without established ratios may participate under observation only.

You may not qualify if:

  • Subject will not tolerate tape adhesive in the area of Harmony 1 Sensor placement as assessed by qualified individuals
  • Subject has any unresolved adverse skin condition in the area of Harmony 1 Sensor or device placement (e.g., psoriasis, rash, Staphylococcus infection)
  • 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
  • Subject is female and has a positive pregnancy screening test
  • Females of child bearing age and who are sexually active should be excluded if they are not using a form of contraception deemed reliable by investigator
  • Subject is female and plans to become pregnant during the course of the study
  • Subject has had a hypoglycemic seizure within the past 6 months
  • Subject has had hypoglycemia resulting in loss of consciousness within the past 6 months prior to screening visit
  • Subject has had an episode of diabetic ketoacidosis (DKA) within the past 6 months prior to screening visit.
  • Subject has a history of a seizure disorder
  • Subject has central nervous system or cardiac disorder resulting in syncope
  • 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
  • Subject has a hematocrit (Hct) lower than the normal reference range
  • Subject has a history of adrenal insufficiency
