The Statins on Glucose Homeostasis in Subjects With Impaired Fasting Glucose

November 15, 2013 updated by: vghtpe user, Taipei Veterans General Hospital, Taiwan

The Influence of Statins on Glucose Homeostasis and the Biomarkers of Diabetes in Subjects With Impaired Fasting Glucose

Evaluate the effects of rosuvastatin (maybe the highest diabetogenic) and pravastatin (seems to be protective) on the glucose homeostasis and other biomarkers in subjects with impaired fasting glucose.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Statin therapy effectively reduces cardiovascular events. However, trial data1 and meta-analyses suggest that statins also confer increased risk of development of diabetes. In order to elucidate whether statins increase risk of diabetes, investigators conducted this study to evaluate the effects of rosuvastatin (maybe the highest diabetogenic) and pravastatin (seems to be protective) on the glucose homeostasis and other biomarkers in subjects with impaired fasting glucose.

Phase

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Glucose homeostasis
Time Frame: 6 months

Compare the glucose homeostasis and some biomarkers of diabetes among control, parvastatin and rosuvastatin groups.

Glucose and insulin response during OGTT. Some markers of insulin resistance and insulin secretion calculated from OGTT.
6 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Some biomarkers of diabetes
Time Frame: 6 months
Such as GLP-1, GIP, IGF-1, HbA1c, FPG etc.
6 months
Progression of glucose homeostasis
Time Frame: 5 to 10 years.
We will repeat FPG and A1C every 6 months and OGTT every 1-2 years for up to 10 years to investigate the change of these parameters.
