Brief Summary

Resveratrol is derived from plants and is found in highest levels in red wine and the skin of red grapes. A recent study reported that monthly and weekly consumption of red wine is associated with a lower risk of dementia. There is compelling evidence that caloric restriction can improve overall health by activating a class of enzymes known as Sirtuins. 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.

Outcome Measures

Primary Outcomes (2)

  • Number of Adverse Events

    The safety and tolerability of treatment with resveratrol will be assessed by analysis of adverse events, including symptoms, abnormal findings on physical examinations, standard laboratory tests and PK analysis of resveratrol and its major metabolites. The frequencies of adverse events or laboratory abnormalities between the participants who receive resveratrol and those receiving placebo will be compared.

    Baseline, Weeks 6, 13, 19, 26, 32, 39, 45, and 52

  • Change From Baseline in Volumetric Magnetic Resonance Imaging (MRI)

    MRI will be used to assess the effect of treatment on rate of whole brain volume

    Baseline and Week 52

Secondary Outcomes (2)

  • Change in Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL)

    Week 52

  • Comparison of the Response to Treatment of Resveratrol Based on ApoE Genotype

    Week 52

Study Arms (2)

Resveratrol

EXPERIMENTAL

Subjects will take 500 mg by mouth once daily increasing at 13 week intervals to a maximum of 1 gram by mouth twice daily with or without food.

Drug: Resveratrol

Placebo

PLACEBO COMPARATOR

Subjects will receive a matching placebo to be taken with or without food.

Drug: Placebo

Interventions

The dosage will begin at 500 mg taken once daily and increase at 13 week intervals to 1 gram taken by mouth twice daily, supplied as 500 mg capsules (two capsules twice daily).

Resveratrol

The matching placebo will begin at a capsule taken once daily and increase at 13 week intervals to two capsules twice daily.

Placebo

Eligibility Criteria

Age50 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of probable AD (NINDS-ADRDA criteria).

  • Caregiver/Study Partner who has direct contact with the participant more than 2 days per week to accompany participant to all visits.
  • MMSE score between 14 and 26 (inclusive).
  • Modified Hachinski score of less than or equal to 4.
  • Able to abstain from ingesting large quantities of resveratrol-containing foods (including red wine). 1-2 glasses of red wine or red grape juice daily acceptable; 1 serving of red grapes daily acceptable.
  • Able to abstain from ingesting herbal/natural preparations or dietary supplements containing resveratrol.

You may not qualify if:

  • Non-AD dementia.
  • Probable AD with Down syndrome.
  • History of clinically significant stroke.
  • Current evidence or history in past two years of epilepsy, focal brain lesion, head injury with loss of consciousness or DSM-IV criteria for any major psychiatric disorder including psychosis, major depression, bipolar disorder, alcohol or substance abuse.
  • Sensory impairment that would preclude the participant from participating in or cooperating with the protocol.
  • Use of investigational agent within two months of Screening.
  • Evidence of any significant clinical disorder or laboratory finding that renders the participant unsuitable for receiving an investigational drug including clinically significant or unstable hematologic, hepatic, cardiovascular, pulmonary, gastrointestinal, endocrine, metabolic, renal or other systemic disease or laboratory abnormality.
  • Active neoplastic disease, history of cancer five years prior to screening, including breast cancer (history or skin melanoma or stable prostate cancer are not excluded).
  • History of seizure within past five years.
  • Pregnancy or possible pregnancy.
  • Use of resveratrol containing supplements.

Limitations and Caveats

This phase 2 study has limitations. A larger study is required to determine whether resveratrol may be beneficial. More potent and bioavailable SIRT1 activators are also in development.
