Clinical Trial Summary

The AKK formula, a prebiotic blend, can effectively promote the proliferation of A. muciniphila. In this study, we attempt to explore the clinical efficacy of AKK formula for A. muciniphila proliferation and weight management.

Description:

This is a double-blind, randomized, parallel and placebo-controlled study. Subjects are informed to consume the samples daily for 8 weeks. The person who is evaluated as obesity by the investigator will be invited to participate in this trial. In this study, we attempt to explore the clinical efficacy of AKK formula for A. muciniphila proliferation and weight management.

• Subject has a condition that, in the opinion of the Study Investigator, would interfere with his/her ability to provide informed consent, comply with the study protocol, confound interpretation of study results, or place the subject at undue risk.

• Female subjects who typically experience changes in GI symptoms or bowel habits (e.g., increased or decreased laxation, bloating, abdominal cramping) at the time of menstruation.

• Female subjects with irregular menstruation which does not allow for easy scheduling of stool collection outside of the menstrual period.

• Female subject who is pregnant, planning to be pregnant during the study period, lactating, or is of childbearing potential and is unwilling to commit to the use of a medically approved form of contraception throughout the study period. Subjects who become pregnant during the study will be dismissed from the study.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Relative abundance of Akkermansia muciniphila in gut	Collect subject's feces for bacterial analysis. Akkermansia muciniphila will be quantified by quantitative PCR.	Change from Baseline relative abundance of A. muciniphila at 8 weeks
Primary	The change of waist circumference	The waist circumference will be assessed by measuring tape. Unit: centimeter	Change from Baseline waist circumference at 4 weeks, and 8 weeks
Primary	The change of Waist-to-height ratio	Waist-to-height ratio can be obtained by dividing waist size by height and is an effective indicator of risks associated with obesity.	Change from Baseline Waist-to-height at 4 weeks, and 8 weeks
Primary	The change of body mass index (BMI)	BMI is a measurement of a person's leanness or corpulence based on their height and weight, and is intended to quantify tissue mass.The body mass index (BMI, kg/m^2) and body mass (kg) will be assessed by InBody.	Change from Baseline BMI at 4 weeks, and 8 weeks
Secondary	The change of total body mass	The total body mass (kg) will be assessed by Bioelectrical impedance analysis (BIA).	Change from Baseline total body mass at 4 weeks, and 8 weeks
Secondary	The change of total lean mass	The total lean mass (kg) will be assessed by Bioelectrical impedance analysis (BIA).	Change from Baseline total lean mass at 4 weeks, and 8 weeks
Secondary	The change of total fat mass	The total fat mass (kg) will be assessed by Bioelectrical impedance analysis (BIA).	Change from Baseline total fat mass at 4 weeks, and 8 weeks
Secondary	The change of total fat rate	The total fat rate (%) will be assessed by Bioelectrical impedance analysis (BIA).	Change from Baseline total fat rate at 4 weeks, and 8 weeks

Secondary	The change of High Density Lipoprotein Cholesterol (HDL-C)	Venous blood will be sampled to measure concentrations of HDL-C.	Change from Baseline HDL-C at 8 weeks

Secondary	The change of intestinal microbiota	Collect subject's feces for bacterial analysis. Intestinal microbiota will be assessed by Next Generation Sequencing (NGS).	Change from Baseline intestinal microbiota at 8 weeks
Secondary	The change of gastrointestinal tolerability	Gastointestinal tolerability will be assessed by The Gastrointestinal Symptom Rating Scale (GSRS).The GSRS has a seven-point graded Likert-type scale where 1 represents absence of troublesome symptoms and 7 represents very troublesome symptoms.	Change from Baseline gastrointestinal tolerability at 4 weeks, and 8 weeks
Secondary	The change of stool type	The stool type will be assessed by The Bristol Stool Form Scale (BSFS) daily. The BSFS is a scale that classifies stools, ranging from the hardest (type 1) to the softest (type 7).	Change from Baseline gastrointestinal tolerability at 4 weeks, and 8 weeks
