Official title

A Randomized Phase II Study to Evaluate Oral RQC for the Prevention of Alzheimer's Disease and Retinal Amyloid-β

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The goal of this clinical trial is to evaluate whether oral resveratrol, quercetin, and curcumin (RQC) can prevent the accumulation of retinal amyloid-β and/or cognitive decline over 24 months in adults aged 50-90 with Stage 1 or 2 Alzheimer's disease as described in FDA-2013-D-0077. The trial will also evaluate the safety and tolerability of RQC. Curcumin, which binds to amyloid-β, will act as a fluorescent label to identify retinal amyloid-β in vivo using optical coherence tomography (OCT)-autofluorescence imaging. The investigators will longitudinally evaluate the effect of RQC on retinal amyloid-β load cognitive outcomes including the Clinical Dementia Rating Scale Sum of Boxes (CDR-SB) and the Mini Mental State Examination (MMSE), and potential microvascular biomarkers. The investigators will also evaluate associations between retinal amyloid-β and progression to early Alzheimer's disease (mild cognitive impairment). The investigators will compare RQC, taken daily for 24 months, with curcumin alone, taken only during the 7 days preceding each of the six study visits to see if RQC can prevent (or reduce) amyloid-β and prevent the onset of mild cognitive impairment.
