What is the Effects of Incretin on the Blood Pressure and Lipid in Overweight or Obese Diabetes Patients With Masked Hypertension: Liraglutide Plus Mitiglinide Comparing Metformin Plus Mitiglinide or Mitiglinide Alone（BLOOD STUDY）

Obesity is one of the characteristics of type 2 diabetes mellitus. Most of the obese diabetes patients are combined with dyslipidemia or hypertension. The clustering of diabetes, obesity, hypertension and dyslipidemia increases the risk of cardiovascular events for patients. GLP-1 (glucagon like peptide-1) is a kind of incretin discovered in recent years. It was reported that beside its hypoglycemic and losing weight effects, activator of GLP-1 receptor could decrease blood pressure and improve lipid metabolism. Therefore, activation of GLP-1 receptor may become a new comprehensive treatment strategies for improving glucose and lipid metabolism, blood pressure level and cardiovascular complication. But, it is lack of evidence-based medicine proof on the relationship between GLP-1 and blood pressure or serum lipid. So, investigators designed a prospective, randomized, open-label, active control study, and try to evaluate the effects of activator of GLP-1 receptor (liraglutide) on lowering blood pressure, improving vascular function and lipid metabolism in overweight or obese type 2 diabetic patients with masked hypertension.

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
