About this study

Official title: Phase II Grape Seed Extract as Anti-Oligomerization Agent in Alzheimer's Disease

Alzheimer Disease (AD) is a progressive brain disease generally known as senile dementia. Our proposed study will establish safety and pharmacokinetics of Meganatural-AZ GSPE in AD subjects. As secondary measures, we will also provide the essential human data to guide the design of future studies to test the efficacy of GSPE in mitigating cognitive deterioration in AD patients.

Read the detailed description

This study aims to establish the safety and pharmacokinetics of Meganatural-Az® GSPE in subjects with Alzheimer's disease. As a secondary goal, clinical and biomarker indices of therapeutic efficacy will also be evaluated. The proposed study will provide the essential human data necessary to guide the design of future studies testing the efficacy of GSPE in mitigating cognitive deterioration in AD patients.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Meganatural-Az Grapeseed Extract in people with Alzheimer's Disease, run by Hillel Grossman at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 11 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: difficulty with enrollment due to pandemic.). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pharmacokinetic analysis (time frame: up to 22 months). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Oct 2024.
