Risk Evaluation & Education for Alzheimer's Disease (REVEAL) IV

Status Completed

Clinical Trial Summary

This study is intended to examine the impact of receiving a genetic risk assessment for Alzheimer's disease (AD) among individuals with Mild Cognitive Impairment (MCI).

Clinical Trial Description

Alzheimer's disease is a common condition affecting memory and thinking. Genes can sometimes be used to provide risk estimates for the eventual development of certain common diseases. Apolipoprotein E (APOE) is one gene which can provide information about a person's chances of developing Alzheimer's disease.

Some people with a diagnosis of Mild Cognitive Impairment (MCI) are curious to learn more about the chance of developing Alzheimer's disease. In the REVEAL IV Study, we are examining the psychological and behavioral impact of learning genetic risk information pertaining to the chance for an individual with MCI to progress to dementia of the Alzheimer's type within three years.

Participation in this study requires an initial phone call which will elicit some demographic information about the participant and his or her study partner. A first in-person visit to the research clinic will consist of an education session, the administration of knowledge and attitudinal surveys and some tests to assess memory and thinking skills. This visit will take approximately 2-3 hours. Participants with MCI will have their blood drawn for genetic testing. Participants will then be randomized to one of two groups. Those in the intervention arm will receive a three-year risk estimate for the chance of progressing to dementia of the Alzheimer's type based on age, the diagnosis of MCI and their own APOE gene test result. Those in the comparison arm will receive a three-year risk estimate for the chance of progressing to dementia of the Alzheimer's type based on age and the diagnosis of MCI, without the APOE gene test result. Participants randomized to the comparison arm will have the opportunity to learn their own APOE gene test result at the end of the study. Participants and their study partners will be followed for 6 months following disclosure of results with 1 additional clinic visit and 1 additional phone interviews. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
