Clinical Trial Summary

Approximately 90 patients, aged 50 to 80 years, with a diagnosis of early Alzheimer's disease will take part in this research study. This study will be conducted in the US. There will be 3 treatment groups: 2 Active doses and 1 group will receive placebo completely by chance. Patients, caregiver, Sponsor, nor study staff will know which treatment is assigned. There are 3 periods in this study: Screening to confirm suitability, Treatment to receive study medication, and Follow-up to check overall health post-participation

Description:

This is a randomized, placebo-controlled, double-blind, parallel-group study that will assess the safety, tolerability, and potential efficacy of Trappsol Cyclo in patients with EAD as defined according to the FDA Guidance for Industry on Early Alzheimer's Disease: Developing Drugs for Treatment. The study will enroll approximately 90 (30 patients/treatment arm) male and female patients aged 50 to 80 years at Screening with characteristic pathophysiologic changes of AD who meet National Institute on Aging-Alzheimer's Association (NIA-AA) criteria for either AD with MCI or mild AD collectively known as EAD (Stages 3 and 4). Enrolled patients must have evidence of progressive cognitive decline in the last year as determined by serial cognitive test scores, if available, or patient or informant/caregiver/study partner (hereafter called caregiver) report as documented by the Investigator
