To Evaluate the Effect of Liraglutide on Ambulatory Blood Pressure-A Pilot Study

Diabetes Mellitus, Non-Insulin-Dependent Clinical Trial

Official title: To Evaluate the Effect of Liraglutide on Ambulatory Blood Pressure-A Pilot Study

Status Completed

Clinical Trial Summary

The investigators are conducting this research to study the effect of Liraglutide on blood pressure. Several studies have shown increased cardiovascular complications and deaths in diabetics with hypertension. The importance of blood pressure control in diabetes has been shown in many clinical trials. No drug already approved for treating Type 2 Diabetes Mellitus is known to reduce blood pressure along with improving diabetes. However, prior research studies with liraglutide have suggested that treatment with liraglutide improves blood pressure. This effect is seen very quickly and even prior to any weight loss. The mechanism behind this effect is yet to be determined.

Clinical Trial Description

The investigators are conducting this research to study the effect of Liraglutide on blood pressure. Several studies have shown increased cardiovascular complications and deaths in diabetics with hypertension. The importance of blood pressure control in diabetes has been shown in many clinical trials. No drug already approved for treating Type 2 Diabetes Mellitus is known to reduce blood pressure along with improving diabetes. However, prior research studies with liraglutide have suggested that treatment with liraglutide improves blood pressure. This effect is seen very quickly and even prior to any weight loss. The mechanism behind this effect is yet to be determined.

Blood pressure will be monitored using the 24 hour Ambulatory Blood Pressure monitor: a device that monitors your blood pressure while you continue normal activity. We have chosen this method to monitor blood pressure because most of the prior studies have proven it to be superior over a single blood pressure recording and its ability to better predict clinical outcomes.

It is well known that both diabetes and hypertension cause endothelial dysfunction. Endothelium is the inner lining of the blood vessels. When it is functioning, it is supposed to regulate blood clotting, help with the body's immune response, controls the volume of fluid and other substances that pass through the blood vessels. Hence, normal endothelial function protects the blood vessels from atherosclerosis (hardening) and builds up of plaque. When it is not functioning well (as in diabetes, hypertension, cigarette smokers etc.) it does not perform one or more of these functions. Hence, in this study, we will also measure the endothelial function using a machine: ENDO PAT.

This is a non-invasive diagnostic test which is done in the doctor's office. Usually takes about 15 minutes. It is not painful. It generates an EndoScore which indicates the current state of the endothelial health.

This is a PILOT study (a small-scale study designed to determine if a larger, full-scale study is doable) to prove this effect which if proven will be extended to a larger, multicenter trial.

Of note: Liraglutide has already been approved for treating Type 2 Diabetes Mellitus. ;
