Main Inclusion Criteria:

  1. Subjects with type 2 diabetes mellitus;

Main Exclusion Criteria:

  1. Subjects with a history of taking hypoglycemic drugs;
  2. Subjects who are pregnant or in lactation;

  5. Subjects with liver and kidney dysfunction (alanine transaminase(ALT) / aspartate aminotransferase(AST)≥2.5×the upper limit of normal(ULN) set by the hospital, serum creatinine>1×ULN set by the hospital, or eGFR<60mL/min/1.73m2);
  6. Surgery with serious cardiovascular and cerebrovascular diseases (such as heart failure, myocardial infarction, cerebral infarction, acute myocarditis, severe arrhythmia, patients receiving interventional therapy, etc.) or stage III hypertension (systolic blood pressure cannot be controlled below 160 mmHg with three antihypertensive drugs);
  7. Subjects with acute diabetic complications such as diabetic ketoacidosis or diabetic hyperosmolar coma in the past 3 months;
  8. Subjects with a medical history of malignant tumor (except local skin basal cell carcinoma) in the past 5 years;
  9. Subjects with a medical history of intestine, or other digestive tract surgery (such as cholecystectomy) within one year, or other non-gastrointestinal surgery within 6 months;
  10. Any condition that in the judgement of the investigator precludes participation.

Glycated haemoglobin (HbA1c)
2-hour post-prandial plasma glucose levels
Fasting serum insulin levels
2-hour post-prandial serum insulin levels

Area of visceral and subcutaneous fat
Waist and hip circumference
Energy expenditure
using metabolic chamber to measure energy expenditure
Blood metabolomics profile measurement
In aid of LC/MS and GC/MS technique, etc, we will measure the metabolomics molecular profile in blood samples before and after treatment. The metabolomics measurement will help to detect the profile of all kinds of bile acid species, lipids species and amino acid species, etc. The composition change of all these biological molecular induced by the treatment is our major interest rather than single molecular quantification.

5. Study Description

Brief Summary
The purpose of this study is to conduct a randomized, double-blinded, placebo-controlled, multicenter clinical trial, evaluating the glucose-lowering and weight-loss effects of Akkermansia muciniphila WST01 strain in overweight or obese patients with Type 2 Diabetes.
Detailed Description
In the present study, about 60 overweight/obese and drug naïve type 2 diabetes patients will be enrolled from multiple centers in China. After screening, eligible subjects will be randomized (1:1) into two groups, taking either Akkermansia muciniphila WST01 strain product or placebo product for 12 weeks. Blood, feces and urine samples will be collected before and after treatment. Metabolic parameters including waist and hip circumference, area of visceral and subcutaneous fat, glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), postprandial plasma glucose (PPG), insulin, glucagon-like peptide 1 (GLP-1), inflammation factors and lipid levels will be measured. Furthermore, the change of gut microbiota and metabolites will be evaluated too. The primary objective is to determine whether Akkermansia muciniphila WST01 strain has a positive effect in patients with Type 2 Diabetes. The secondary objective is to explore the effect of Akkermansia muciniphila WST01 strain on safety, intestinal flora, insulin sensitivity, and other metabolic indicators and metabolites in the patients.
