About this study

Official title: A Phase II, Double-Blind, Placebo-Controlled Study of the Safety and Tolerability of Two Doses of Curcumin C3 Complex Versus Placebo in Patients With Mild to Moderate Alzheimer's Disease

The purpose of this study is to examine the safety and tolerability of curcumin, and to determine its effect on patients with mild to moderate Alzheimer's Disease (AD).

Read the detailed description

Curcumin, a yellow substance found in the spice Turmeric, has antioxidant, non-steroidal anti-inflammatory (NSAID), and cholesterol-lowering properties, all of which make it a good candidate in the prevention and treatment of AD. The study will examine the safety and tolerability of 2 different doses of curcumin C3 complex. Blood and cerebrospinal fluid (CSF) tests will be used to examine how the curcumin is absorbed in the body, and whether it has an effect on inflammation, oxidative damage, and cholesterol levels. Participants will also be tested to determine the potential effect of curcumin on cognition, behavior, and daily function in patients with mild to moderate AD.

Participants will be randomly assigned to receive one of two doses of curcumin, or a placebo, for the initial 6 months of the trial. For the final 6 months, those receiving a placebo will be switched to one of the two doses of the drug. The 33 participants will make 7 visits to the study site over a 12-month period. These visits may include a physical and neurological examination, routine laboratory tests, lumbar puncture, and neuropsychological (mood and memory) evaluations.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Curcumin C3 Complex in people with Alzheimer's Disease, run by John Douglas French Foundation 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 7 inclusion and 11 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: finished, as of the sponsor's last update on 3 Dec 2009. 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. 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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Side effect checklist. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00099710, which also lists 4 linked publications.

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 3 Dec 2009.
