Eligibility Criteria

21 Years - 70 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

    Note: All subjects may be asked to test during the night if clinically indicated.

  11. Participant must have a primary care provider

Exclusion Criteria:

  1. History >2 episodes of severe hypoglycemia (see definition below) in the past year, or hypoglycemic unawareness when glucose levels are ≤ 50 mg/dl;
  2. Significant physical, psychological, or cognitive impairment that would prohibit adherence to the protocol at the discretion of the PI;
  3. Splitting Lantus and taking Lantus twice a day
  4. Severe cardiovascular disease including a history of congestive heart failure, unstable angina, myocardial infarction or stroke within the 6-months preceding enrollment;
  5. Active anemia w/ hematocrit ≤ 25% in women or 30% in men;
  6. Advanced kidney disease Stage 4 (eGFR < 30 ml/min) and above
  7. Active cancer or cancer in the past 2-years (except non-melanoma skin cancer)
  8. History of significant liver disease including cirrhosis or elevated liver enzymes (e.g., AST and ALT greater than 3 times the upper limit of normal values).
  9. BMI > 45 kg/m2
  10. Are pregnant, plan to become pregnant during the study period, or are breastfeeding.
  11. Have a BGMS that cannot be downloaded.

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Active Comparator

Arm Label

d-Nav Device

Blood Glucose Monitoring System

Arm Description

d-Nav Device: daily use to provide insulin dosage updates weekly - or sooner when needed based on analyzes and evaluates the historical blood glucose patterns. Insulin dosage is adjusted as required

Patient's personal Over the Counter Blood Glucose Monitoring System (OTC BGMS) for daily glucose testing to determine insulin dosage needed. Insulin dosage is adjusted as required

Outcomes

Primary Outcome Measures

Reduction in HbA1C
To demonstrate a greater reduction in HbA1c at 6-months for d-Nav users compared to control patients in the primary cohort.

Secondary Outcome Measures

Comparison Percent Reduction HbA1c
To determine the difference between the Control and d-Nav group in the percent of participants who achieve A1c < 7.0%, < 8.0%, and >9.0% at 6 months
Number of Glucose Readings <70 mg/dl
To determine the difference between the Control and d-Nav group in the number of glucose readings <70 mg/dl (symptomatic or asymptomatic) utilizing the documented downloaded glucose values.
Change in Rate of Hypoglycemia
To determine change (if any) in rate of hypoglycemia, during the study for d-Nav users in the secondary cohort
Comparison Percent Reduction HbA1c w/out Hypoglycemia
To determine the difference between the Control and d-Nav group in the percent of participants who achieve A1c < 7.0%, < 8.0% without a severe hypoglycemia event at 6 months.

5. Study Description

Brief Summary
Hygieia Research seeks to conduct a prospective randomized clinical study involving adult subjects with uncontrolled Type-2 diabetes requiring insulin. The study seeks to demonstrate that the clinical application of the d-Nav will achieve metabolic control in a safe and effective manner.
Detailed Description
The purpose of this study is to demonstrate that the use of d-Nav (d-Nav group) is superior to titration of insulin dosage relying on data from glucose meters with health care provider support (Control) in the management of insulin treated diabetes, by randomizing 200 insulin treated subjects with type 2 diabetes. Primary Objective: To demonstrate a greater reduction in HbA1c at 6-months for d-Nav users compared to control patients in the primary cohort.
