The Effect of Short-Term Statins and NSAIDs on Levels of Beta-Amyloid, a Protein Associated With Alzheimer's Disease

March 3, 2008 updated by: National Institute of Mental Health (NIMH)

The Effect of Short-Term Statin and NSAID Treatment on CSF Beta-Amyloid

The purpose of this study is to determine whether short-term use of the drugs ibuprofen and lovastatin affects levels of a protein called beta-amyloid in people who are at risk for developing Alzheimer's Disease (AD).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

There is increasing evidence that nonsteroidal and cholesterol lowering medications may be associated with a delay in the onset of Alzheimer's disease (AD). There is separate evidence that beta-amyloid(1-42) is involved in the pathophysiology of AD and levels of beta-amyloid(1-42) in the cerebrospinal fluid (CSF) of AD patients are significantly lower than that found in controls. It has been suggested that these standard medications may have indirect effects that alter the normal course of AD, but there is no data to directly support this contention in humans. Based on previous work, it is our hypothesis that CSF beta-amyloid(1-42) levels may serve as an early biomarker of AD. Any pharmacological induced change in CSF beta-amyloid(1-42) might have profound implications for the eventual onset of illness. Therefore, the purpose of this study is to evaluate the short-term effects of two commonly prescribed nonsteroidal and cholesterol lowering medications, ibuprofen and lovastatin, on the levels of cerebrospinal fluid beta-amyloid(1-42) in a group of normal controls 'at risk' for developing AD.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
50

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Description

INCLUSION CRITERIA:

  1. Normal volunteer over the age of 18
  2. Cognitively within normal limits at baseline evaluation
  3. Previously evaluated in Protocol 95-M-0096
  4. Women of child-bearing potential will be advised not to become pregnant during the treatment period

EXCLUSION CRITERIA:

  1. Known allergies to lovastatin or ibuprofen
  2. Use of regular dosing of NSAID or statin during the previous month
  3. Concurrent use of cyclosporine, itraconazole, ketoconazole, gemfibrozil, niacin, erythromycin, clarithromycin, HIV protease inhibitors or nefazodone because of possible drug interactions with lovastatin.
  4. Women who are currently pregnant
  5. Concurrent use of anticoagulants, aspirin, beta-adrenergic agents, cimetidine, digoxin and oral hypoglycemics because of possible drug interactions with ibuprofen.
  6. Peptic ulcer disease by history
  7. Autoimmune disease by history
