简要总结
The purpose of this pilot study is to determine the effects of two human microbiome formulations (MET-3 and MET-5) on fasting serum TG concentration.
详细描述
Obesity is a condition characterized by an excess amount of body fat, and is defined as a body mass index (BMI) of 30 kg/m² or greater. The rising prevalence of obesity in all parts of the world is of great public health concern due to the fact that obesity is associated with many causes of morbidity and mortality. Excess body fat accumulates when energy intake is greater than energy expenditure and recently, the role of the colonic microbiome has been highlighted as a potential contributor to energy balance. The obese microbiome is suggested to promote obesity due to an excess production of short-chain fatty acids, and, thus, increased colonic energy availability.
The purpose of this pilot study is to determine the effects of two human microbiome formulations (MET-3 and MET-5) on fasting serum TG concentration.

- •Willing to abstain from strenuous exercise, consuming alcoholic drinks 24 hours before study days and during study days;
- •Willing to maintain current dietary supplement and medication use throughout the trial. On test days, subject agrees to bring any dietary supplements or medications taken in the morning with them to the clinical site to take just prior to the glucose test meal;
- •Subject is not currently participating nor recently (within 30 days of screening) participated in a clinical trial involving long-term exposure (greater than 24 hours) to an investigational drug, nutritional supplement or lifestyle modification;
- •Understanding the study procedures and willing to provide informed consent to participate in the study and authorization to release relevant protected health information to the study investigator and other authorized agents as indicated in the consent form.
排除标准
- •Failure to meet any one of the inclusion criteria.
- •Known history of AIDS, hepatitis, a history or presence of clinically important endocrine conditions (including Type 1 or Type 2 diabetes mellitus), pulmonary, biliary or gastrointestinal (GI) disorders or new onset cardiovascular disease within 6 months of screening (including, but not limited to, atherosclerotic disease, history of myocardial infarction, peripheral arterial disease, stroke).
- •Use of antibiotics within 1 week of screening.
- •Use of probiotic supplements within 1 week of screening.
- •Use of medications known to influence carbohydrate metabolism, GI function or appetite, including, but not limited to adrenergic blockers, diuretics, thiazolidinediones, metformin and systemic corticosteroids within 4 weeks of the screening visit, or with any condition which might, in the opinion of the Investigator, either: a) make participation dangerous to the subject or to others, b) affect the results, or c) influence the ability of the subject to comply with study procedures.
- •Major trauma or surgical event within 3 months of screening.
- •Unwillingness or inability to comply with the experimental procedures and to follow study safety guidelines.

研究组 & 干预措施
MET-5 2.5 g daily for 4 weeks
MET-5 is a new product composed of twenty-six strains of bacteria isolated from the stool of a different healthy donor than MET-3. Although it is expected to work in a similar fashion to MET-3, it contains some strains that are unique in comparison to the original MET-3 formulation and have been associated with leanness in the scientific literature. MET-5 is provided in capsule form and 5 capsules will be swallowed by each subject once daily for 4 weeks.
干预措施: MET-3 (Biological)
MET-3 2.5 g daily for 4 weeks
MET-3 is composed of twenty-two strains of bacteria and was designed to treat metabolic syndrome. The strains that were selected are based on strains that are known butyrate producers, associated with healthy subjects and improved gut barrier function. MET-3 is provided in capsule form and 5 capsules will be swallowed by each subject once daily for 4 weeks.
