Title

A Double-Blind, Placebo-Controlled Safety and Efficacy Study of NA-831
A Randomized, Double-Blind, Placebo-Controlled Study to Assess the Safety, Tolerability, and Efficacy of NA-831 in Alzheimer Patients With Mild Cognitive Impairment
This study seeks to evaluate the efficacy and safety of NA-83 in subjects with mild cognitive impairment due to Alzheimer's Disease
Mild cognitive impairment ("MCI") is defined as the "symptomatic pre-dementia stage" on the continuum of cognitive decline. Currently, no medications have proven effective for MCI. Preclinical experiments indicate that NA-831 is an endogenous small molecule that exhibits neuroprotection, neurogenesis, and cognitive protective properties across a range of disease models. NA-831 has been shown to be safe and well tolerated in healthy volunteers. This study seeks to evaluate the efficacy and safety of NA-83 in 126 subjects with mild cognitive impairment due to Alzheimer's Disease

Treatment with any investigational drug, biologic, or device within the previous 30 days prior to screening.
Surgery involving general anesthesia within the past 3 months or planned surgery requiring general anesthesia during the study period.
Contraindications to study procedures
Use of any medications that, in the opinion of the Investigator, may contribute to cognitive impairment, put the participants at higher risk for adverse events (AEs), or impair the participant's ability to perform cognitive testing or complete study procedures.
