Brief Summary

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

The goal of this clinical trial is to learn if tributyrin can help prevent or mitigate cognitive decline in individuals with mild Alzheimer's disease (AD). The trial will also examine the safety and effects of tributyrin on inflammation and gut microbiota. The main questions it aims to answer are:

Does tributyrin reduce inflammation and neurodegeneration markers? How does tributyrin affect gut microbiota and intestinal permeability? Researchers will compare tributyrin to a placebo (a look-alike substance that contains no active ingredient) to evaluate its effectiveness.

Participants will:

Take tributyrin or a placebo every day for 12 weeks. Undergo assessments of cognitive function, blood markers (such as NfL and pTau217), and gut health.

The findings are expected to provide insight into the potential of tributyrin as a preventive intervention for Alzheimer's disease.

Participants Investigators
The process of random assignment of participants will be carried out using opaque envelopes containing the assignment to the butyrate group (experimental group) and the CG group (control group).

Study Groups

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

Tributyrin

Participants will receive 1 capsule per day for 12 weeks. Each capsule contains 450 mg of tributyrins. The capsules will have a gelatin coating. In the market, formulations are available with dosages ranging from 200 to 500 mg.

Group Type EXPERIMENTAL

tributyrin

Intervention Type DIETARY_SUPPLEMENT

Participants will receive 1 capsule per day for 12 weeks. Each capsule contains 450 mg of tributyrins. The capsules will have a gelatin coating. In the market, formulations are available with dosages ranging from 200 to 500 mg.

Placebo

The placebo will consist of potato starch encapsulated under identical conditions to those used for the tributyrin capsules, ensuring adequate blinding of the study. The administration of the placebo will follow the same protocol as that of the intervention group.
