Clinical Trial Summary

Alzheimer Disease (AD) is a progressive brain disease generally known as senile dementia. Our proposed study will establish safety and pharmacokinetics of Meganatural-AZ GSPE in AD subjects. As secondary measures, we will also provide the essential human data to guide the design of future studies to test the efficacy of GSPE in mitigating cognitive deterioration in AD patients.

Description:

This study aims to establish the safety and pharmacokinetics of Meganatural-Az® GSPE in subjects with Alzheimer's disease. As a secondary goal, clinical and biomarker indices of therapeutic efficacy will also be evaluated. The proposed study will provide the essential human data necessary to guide the design of future studies testing the efficacy of GSPE in mitigating cognitive deterioration in AD patients.
