Hemoglobin A1c Primary · Baseline, Month 3, Month 6, Month 12

The hemoglobin A1c test result reflects average blood sugar level for the past two to three months. Specifically, the A1c test measures what percentage of hemoglobin is coated with sugar (glycated). The higher A1c level, the poorer blood sugar control and the higher risk of diabetes complications.

Insulin Resistance Score Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) Primary · Baseline, Month 3, Month 6, Month 12

Insulin resistance score HOMA-IR is computed with the formula: fasting plasma glucose (mmol/l) times fasting serum insulin (mU/l) divided by 22.5. Low HOMA-IR values indicate high insulin sensitivity, whereas high HOMA-IR values indicate low insulin sensitivity (insulin resistance).

Sponsor's own description

The pilot study will assess the feasibility and efficacy of cryoablation procedure to freeze the vagus nerve in obese patients with type 2 diabetes. Aim 1 will focus on changes in glycemic control. Aim 2 will evaluate differences in body weight and anthropometric measurements. This study will provide much needed data for a novel therapeutic intervention to manage obese patients with type 2 diabetes.
