About this study

We investigate the clinical efficacy of Panax ginseng in Alzheimer's disease (AD).

Read the detailed description

Alzheimer's disease (AD) is characterized by a progressive decline of memory and intellectual abilities, interfering activity in daily living, the overall quality of life, and ultimately leads to death. Although pharmacologic treatments are currently approved for treating mild- to moderate AD using acetylcholinesterase inhibitors (ACEI) or memantine, the NMDA antagonist, for the advanced stage of AD, the therapeutic efficacies need to be further improved.

For millennia, ginseng or its components have been used to treat medical conditions, and the pharmacologic effects have been demonstrated in cardiovascular, endocrine and immune system (Attele et al., 1999). In means of memory and learning, a number of studies suggested that ginseng can attenuate learning deficits of damaged or ageing brains in rodent models (Kennedy et al., 2003; Zhao and McDaniel, 1998; Nitta et al., 1995). In studies with human healthy participants, correspondently, both acute and chronic dosage of ginseng increased the cognitive performance (Kennedy et al., 2001; Kennedy et al., 2003; D'Angelo et al., 1986; Sorensen and Sonne, 1996).

In this study, we we will investigate the contribution of ginseng treatment in increasing the cognitive improvement of AD patients. In addition, we will test various bio-markers and hematopoietic progenitor cell count in those included patients using their blood samples. Patients with AD as well as memory decline will be included

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Panax Ginseng in people with Alzheimer's Disease and Memory Decline, run by Seoul National University Hospital.

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 1 inclusion and 1 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 24 Oct 2006. Status can change between updates, so confirm with the study contact before making plans.

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 combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Cognitive performances monitored by MMSE and Alzheimer's disease assessment scales.. 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?

On the ClinicalTrials.gov record for NCT00391833, which also lists 1 linked publication.

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 24 Oct 2006.
