Study Description

Brief Summary:

BT-001 is a software program intended to help patients with type 2 diabetes, under the guidance of their physician, improve glycemic control (i.e., levels of blood sugar). The BT-001 software delivers a type of behavioral therapy to patients via a mobile application that targets behaviors related to achieving glycemic control. The effectiveness of BT-001 will be measured by its ability to help patients reduce Hemoglobin A1c, or HbA1c (a marker in the blood that measures blood sugar) compared to standard medical care in patients with type 2 diabetes.

Condition or disease	Intervention/treatment	Phase
Type 2 Diabetes	Device: BT-001; Other: Physician-guided Standard of Care for type 2 diabetes	Phase 3

Detailed Description:

The study will utilize an open-label, randomized, parallel-group design to confirm and characterize the safety and efficacy of BT-001 used in addition to standard of care (SOC) when compared to SOC alone in patients with type 2 diabetes. The screening period will consist of a run-in during which time HbA1c will be assessed for confirmation of eligibility.

Once confirmed to be eligible, patients will then be randomized 1:1 to the following groups:

Investigational: One half of the participants will be treated with BT-001 plus SOC for 180 days;

Control: One half of the participants will be treated with SOC alone for 180 days.

Arms and Interventions

Arm	Intervention/treatment
Experimental: BT-001 + Standard of Care; BT-001 is a software program used with physician guidance, being investigated to improve glycemic control. Patients randomized to this arm of the study will interact with the BT-001 software program in addition to receiving Standard of Care for type 2 diabetes	Device: BT-001; BT-001 is a software program intended to help patients with type 2 diabetes, under the guidance of their physician, improve glycemic control.; Other: Physician-guided Standard of Care for type 2 diabetes; Current ADA Standard of Care Guidelines for type 2 diabetes
Active Comparator: Standard of Care; Patients randomized to the Standard of Care arm will receive Standard of Care treatment for type 2 diabetes under the guidance of a physician	Other: Physician-guided Standard of Care for type 2 diabetes; Current ADA Standard of Care Guidelines for type 2 diabetes

Outcome Measures

Primary Outcome Measures :

1. The difference in the mean change from baseline in HbA1c at Day 90 between Intervention and Standard of Care groups [ Time Frame: Baseline and Day 90 ]
   Hemoglobin A1c (HbA1c) test measures the amount of blood sugar (glucose) attached to hemoglobin.

Secondary Outcome Measures :

1. The difference in the mean change from baseline in HbA1c at Day 180 between Intervention and Standard of Care groups [ Time Frame: Baseline and Day 180 ]
   Hemoglobin A1c (HbA1c) test measures the amount of blood sugar (glucose) attached to hemoglobin.

Eligibility Criteria

• Ages Eligible for Study: 18 Years to 75 Years (Adult, Older Adult)
• Sexes Eligible for Study: All
• Accepts Healthy Volunteers: No

Criteria

Inclusion Criteria:

4. Possesses a smartphone (iPhone or Android only) capable of running the smartphone applications (Apps) used in the study;
5. Has had no change in the last 4 months prior to randomization (3 months prior to initial screening plus 30-day run-in screening period) in antihyperglycemic medications;
6. Has a current HbA1c level >7%, as determined by both screening assessments;
7. Willing to use an FDA approved glucometer for self-monitoring blood glucose throughout the study;
8. Is capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the informed consent form (ICF).

Exclusion Criteria

   c. A change in antidepressant or anti-anxiety medication within the past 3 months;

   d. A history of bariatric surgery or planned bariatric surgery during the study;

   e. The current use of marijuana, cocaine, opioid painkillers, or other addictive substances;
