Resveratrol is a substance found in some plants that directly activates sirtuins, mimicking the effects of caloric restriction and may affect regulatory pathways of diseases of aging, including Alzheimer's disease (AD).
In this study, people with AD will be given either Resveratrol or placebo for 12 months to determine whether daily resveratrol therapy is beneficial in delaying or altering the deterioration of memory and daily functioning.
Subjects age 50 and above with a diagnosis of probable AD may qualify for participation in this study. A small group of 15 participants will be asked to take part in a more detailed 24-hour Pharmacokinetic (PK) sub-study that will measure resveratrol levels over a 24 hour period.
This Phase 2 clinical trial is currently scheduled to open in April. There are only 120 available slots.
Right now, there is no location listed for Delray Beach. There are 26 locations listed around the United States. See the list of locations here .
If the clinical trial were available, I would be calling right now to see if they were taking appointments. This is what you should do if you are interested.

This double blind, placebo-controlled trial will be conducted at approximately 26 Alzheimer's Disease Cooperative Study (ADCS) clinical centers.
One hundred twenty (120) patients with mild to moderate dementia due to probable Alzheimer's disease (AD) will be randomly assigned to treatment (1:1) with resveratrol starting at 500 mg once daily or matching placebo, increasing at 13 week intervals to a maximum of 1 gram twice daily (divided into two 500 mg capsules taken orally) taken with or without food.
Participants will be treated for 52 weeks, and will undergo venous blood draws for biomarker analysis at Baseline and at 52 weeks; participants will also undergo two lumbar punctures for biomarker analyses of cerebrospinal fluid (CSF) at Baseline and at Week 52.
Participants will undergo magnetic resonance imaging (MRI) to measure rate of whole-brain and regional atrophy at Screening, Week 13 and Week 52 visits. Randomization will be stratified by site.
For monitoring of potential toxicities of the study drug - particularly nephrotoxicity - subjects will undergo physical examination, neurological examination, adverse event review, blood chemistries to include blood urea nitrogen (BUN) and Creatinine (Cr), pharmacokinetic (PK) analyses for resveratrol and its metabolites, and urinalysis every 6-7 weeks during the study. Clinical, Cognitive and Functional effects of resveratrol and insulin and glucose metabolism will also be assessed.
A subgroup of approximately 15 subjects enrolled will be randomized 4:1 (N = 15, 12 treated + 3 placebo) for more detailed 24-hour PK analysis. For these individuals, blood samples will be collected at 15 different time points. Measurements will include levels of resveratrol and its major metabolites (sulfated- and glucuronidated-resveratrol). These subjects will complete the detailed PK with each dosage step. This 24-hour PK sampling in the subgroup will occur after the first dose following Baseline, after the first dose at each dose increment (Weeks 13, 26 and 39), and after the final dose (Week 52).
Enrollment will be restricted to individuals who are able to abstain from ingesting large quantities of resveratrol-containing foods (including red wine). 1-2 glasses of red wine or red grape juice and 1 serving of red grapes daily is acceptable. Subjects must also be able to abstain from ingesting herbal/natural preparations or dietary supplements containing resveratrol.
