April 20, 2010 updated by: Guang'anmen Hospital of China Academy of Chinese Medical Sciences

Multi-center Randomized Controled and Double Blind Trial of Tang-min-ling Pills in the Treatment of Type 2 Diabetes

Tang-min-ling pills are made by Chinese herbs extract, and data showed they had antidiabetic effects on the experimental rats and no obvious toxicity was found.This is a randomized, doubled blind, dose-paralleled-control multi-centre clinical trial to evaluate the efficacy and safety of Tang-min-ling pills in the treatment of type 2 diabetic patients and explore the optimal dosage of Tang-min-ling pills.

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

Two hundred and ten of overweight patients inflicted with primary diabetes mellitus who had stagnated heat of liver and stomach syndrome were recruited, which were randomly divided into 3 groups, and were given high-dosage (12g Tang-min-ling pills every time), low-dosage (6g Tang-min-ling pills every time)、placebo by 3 times every day for 12 weeks respectively. Hemoglobin A1c (HbA1c), Fasting plasma glucose (FPG)、postprandial 2 hours plasma glucose(2hPG)、syndrome、symptoms、body mass index (BMI)、waist circumference (WC) of these groups were measured and analyzed. Some safety indexes such blood and urine and stool routine examination, electrocardiogram (ECG)and liver and kidney function tests were measured and analyzed during the experiment. The treatment period is 12 week.

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.

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
Hemoglobin A1c (HbA1c)
Time Frame: 12 weeks after treatment
The HbA1c was measured and analyzed twice, one is before the treatment and the other is 12 weeks aftertreatment to make a self comparison.
12 weeks after treatment

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
Fasting plasma glucose (FPG)、postprandial 2 hours plasma glucose(2hPG)、body mass index (BMI)、waist circumference (WC)
Time Frame: 12 weeks after treatment
12 weeks after treatment
symptoms score and Chinese syndrome
Time Frame: 12 weeks after treatment
12 weeks after treatment
The rate of adverse events,the blood and urine and stool routine examination, electrocardiogram (ECG)and liver and kidney function tests
Time Frame: 12 weeks after treatment
The number of participants with adverse events were recorded and compared. The blood and urine and stool routine examination, electrocardiogram (ECG)and liver and kidney function tests were measured and observe the safety.
