Brief Summary

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

Based on prior published pilot studies, the investigators have initiated a larger, multi-site placebo-controlled clinical trial with Alzheimer's disease (AD) patients and individuals diagnosed with Mild Cognitive Impairment (MCI), with the hopes of (1) confirming (or denying) the above promising clinical findings, and (2) determining whether or not our formulation can delay MCI "conversion" to AD.

Detailed Description

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

Preclinical studies with mouse models of of age-related neurodegeneration led us to develop a Nutriceutical Formulation ("NF") consisting of 6 over-the-counter vitamins and nutriceuticals, that buffers multiple facets of Alzheimer's disease (AD), including (1) reducing presenilin expression, gamma-secretase activity, Abeta generation and tau phosphorylation, (2) buffering homocysteine and Abeta-induced oxidative damage, (3) reducing aggression, (4) increasing acetylcholine production and improving/maintaining cognitive performance.

A 1-year, open-label trial with NF with mild to moderate AD patients demonstrate improvement in cognitive performance (Dementia Rating Scale, Clock-drawing) within 3-6 months. Caregivers reported maintenance of daily performance and improved mood (ADCS-Activities of Daily Living and NeuroPsychiatric Inventory). A placebo-controlled study with moderate to late-stage AD indicates delayed cognitive decline and maintenance of daily activities. No adverse events were reported.

A multi-site trial with \>90 individuals aged 45-73 without dementia indicated that NF statistically improved executive function (Trails B-A) vs. placebo within 3 months, which increased further at 6 months. The placebo group demonstrated identical improvement in a 3-month open-label extension. Following NF withdrawal, participants returned to baseline; statistically-significant improvement was restored once NF was individuals resumed.

We have initiated a larger, multi-site placebo-controlled clinical trial with AD patients and individuals diagnosed with Mild Cognitive Impairment (MCI), with the hopes of (1) confirming (or denying) the above promising clinical findings, and (2) determining whether or not our formulation can delay MCI "conversion" to AD.
