Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This research study is being done to evaluate the effect of hepatic ultrasound insonification on whole-body insulin sensitivity and evaluate the safety and tolerability of hepatic ultrasound insonification in subjects with Type 2 Diabetes Mellitus (T2DM). "Insonify/insonification" is defined as applying to an area or an object carefully-controlled sound waves, typically as in ultrasound imaging. GE Research is sponsoring this research study. The purpose of this research study is to:
* Evaluate the effect of liver ultrasound waves on changes from baseline in whole-body insulin sensitivity
* Test the safety and tolerability of liver ultrasound waves in subjects with Type 2 Diabetes Mellitus
* Evaluate the effect of liver ultrasound waves on change from baseline in glucose tolerance and insulin secretion
* Evaluate the effect of liver ultrasound waves on glucose metabolism
Insulin sensitivity refers to how sensitive the body's cells are in response to insulin.
Glucose tolerance refers to the body's ability to handle (tolerate) glucose. Insulin secretion is a process in which the body releases insulin in response to glucose levels in the blood becoming elevated.
The study device used in this study is cleared for use by the United States Food and Drug Administration (FDA) for ultrasound diagnostic exams, however it has not been tested or approved specifically for modulation of metabolism in people with diabetes. The use of the study device in this study is investigational and is considered a Non-Significant Risk (NSR).

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This was an open label, exploratory pilot study to assess the effects of hepatic ultrasound insonification on glucometabolic parameters in subjects with T2DM through selective hepatic ultrasound of the porta hepatis region of the liver utilizing pulsed ultrasound. The study was to consist of 1 cohort comprising up to 15 subjects. Dropouts and withdrawals could have been replaced until the anticipated number of subjects completed the study. Finally, the study consisted of one cohort with 36 subjects enrolled, including 20 screen failures, 15 subjects that completed the study (1 completer had an incorrect infusion parameter and was removed from clamp analysis), and 1 subject that was discontinued at the discretion of the Investigator. As this was an exploratory, open-label study, no randomization or blinding was performed and no-unblinding codes were required.
The study included a Screening Period, Observational Period 1, 3 consecutive days of hepatic ultrasound insonification, and Observational Period 2. Each Observational Period was divided into an In-house Period and an Outpatient Visit (OPV). The Screening Period was performed up to 28 days prior to the first In-house Period. For eligible subjects with a body mass index (BMI) \> 35.0 and ≤ 40.0 kg/m2 and/or a waist circumference \> 40 and ≤ 45 inches, an ultrasound examination was added to confirm eligibility, and the Screening Period was extended to at least 30 days. The first Observational Period lasted approximately 2-weeks (Days -1 to 14). On the morning of Day -1, subjects checked into the clinic for a 3-day In-house Period; subjects may have been released from the clinic on Day 2. Subjects were contacted via telephone every other day until the next In-house Period. On Day 8, subjects checked into the clinic for an OPV. On Day 15, subjects checked into the clinic in fasting conditions for a 4-day In-house Period. Insonifications were performed on three consecutive days (Days 15, 16 and 17). Subjects may have been released from the clinic on Day 18. The second Observational Period lasted 11 days (Days 18 to 28). Subjects were contacted via telephone every other day until the Follow-up Visit. On Day 22, subjects checked into the clinic for the OPV. The Follow-up Visit was performed on Day 28.
