Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine the effect of a commercial dietary fiber supplement on patients with type 2 diabetes mellitus, in the way of glucose control, insulin action in the body, and the gut microbiota (bacteria) abundance.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Fiber supplements such as psyllium are known to be beneficial to glycemic control in patients with type 2 diabetes mellitus (T2DM). Gut microbiota has a role in regulating host energy metabolism and systemic inflammation by several pathways such as short-chain fatty acid production, fasting-induced adipose factor expression, endocannabinoid system, and gut epithelial permeability. As dietary components can influence the composition of the microbiota, we hypothesized that fiber supplements could modify gut microbiota and consequently affect glycemic control and inflammatory condition in patients with T2DM.

The primary outcome was to assess the effect of fiber on glucose control (by comparing fasting glucose and glycoalbumin), insulin secretion and sensitivity. Secondary outcomes were the changes abundance of microbiota, incretins, and lipopolysaccharide (LPS).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Agio arm

It is a pilot study based on the proof-of-concept that dietary fiber helps glucose control in patients with type 2 diabetes. As a single-arm study, 'Agiocur Pregranules' (dietary fiber) is administered for 28 days and stopped for next 28 days, in patients with type 2 diabetes.

Group Type OTHER

Agiocur Pregranules

Intervention Type DRUG

6g before breakfast and 12g after dinner for first 28 days, and no medication for next 28 days for washout
