Examining the Effects of Neuromodulation on Glucose Metabolism in Type 2 Diabetes

Device: Investigational Study to Examine the Effects of Neuromodulation on Glucose Metabolism in Type 2 Diabetes

This is an open-label, proof of concept study with a single active treatment arm designed to assess whether CVS-based stimulation has a beneficial effect on patients with type 2 diabetes. The primary outcome measure is a difference between pre and post-treatment A1c.

  • DPP-4 inhibitors (sitagliptin, saxagliptin, alogliptin, linaglyptin)
  • Pioglitazone
• Has an A l c between 7.5 - 9.0% based upon point of care testing performed at visit 1.
• Currently performs self-monitoring blood glucose checks at least 3 times per week.
• Able to adhere to protocol requirements.

Exclusion Criteria

A subject will be excluded if any of the following criteria are met:

• Has Type 1 Diabetes or Gestational Diabetes.
• Is pregnant or planning to become pregnant during the course of the study.
• Current use OR use in the past 6 months of sulfonylureas.
• Current use OR use in the past 6 months of insulin
• History of cardiovascular disease or cerebrovascular disease.
• Any planned surgery during the course of the study.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Caloric Vestibular Stimulation (CVS); The TNM Device will provide a standardized active thermal waveform that will be used for all patients. The device is non-invasive and does not use electrical stimulation.	Device: TNM Device; The device is worn like a music headset and the patient lies on a wedge pillow while the device is active. Each session lasts under 20 minutes.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Measurement of Glycosylated Hemoglobin (A1c)	At the end of the 84 day period of device use, the patient's A1c value will be compared with the baseline value to assess any reduction.	after 84 days of device use

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Measurement of Lipid Panel	At the end of treatment (84 day) period, the patient's fasting lipid panel will be taken and compared with the baseline panel to assess any difference in lipid metabolism.	after 84 days of device use
Assessment of Quality of Life	At the end of the 84 day period of device use, the patient's reports on quality of life measures will be compared with baseline values to assess any improvement.	after 84 days of device use
Assessment of Mood	At the end of the 84 day period of device use, the patient's reports on mood measures will be compared with baseline values to assess any improvement.	after 84 days of device use
Assessment of Diabetes Related Self Care	At the end of the 84 day period of device use, the patient's reports on diabetes related self care will be compared with baseline values to assess any improvement.	after 84 days of device use
Feasibility of the Device as an Intervention for the Diabetes Population	At the end of the 84 day period of device use, the patient will be asked to assess the device use experience and note any shortcomings, challenges or difficulties.	after 84 days of device use
