About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled, Ascending-Dose Phase 1b Safety Study of Three Different Doses of an Alpha-7 Nicotinic Acetylcholine Receptor Agonist (EVP-6124) or Placebo in Patients With Mild to Moderate Probable Alzheimer's Disease

This study is being conducted to determine the safety, tolerability, and pharmacokinetics (PK) of three different doses of an investigational medication, EVP-6124, in individuals with mild to moderate Alzheimer's disease who are also taking an Alzheimer's medication (AChEI [acetylcholinesterase inhibitor]: either donepezil or rivastigmine). In addition, PK of AChEI medications will be assessed. Cognitive function will be evaluated on an exploratory basis.

Read the detailed description

This is a randomized, double-blind, placebo-controlled, Phase 1b safety study of three dose levels of EVP-6124 in subjects with mild or moderate Alzheimer's disease and who are taking an AChEI medication (donepezil or rivastigmine).

Study drug will be supplied as capsules and will be orally administered once daily for a total of 28 days. Eligible subjects will be admitted to an inpatient study unit on Day -2 (two days before the first dose of study drug is administered) and will remain confined to the inpatient study unit for a total of five days. Starting on Day 4, subjects will continue the study in the outpatient setting, with study visits on Days 7, 14, 21, and 28. Safety assessments, PK sampling, and cognitive testing will be performed inpatient and at each study visit.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EVP-6124 (0.1 mg/day), EVP-6124 (0.3 mg/day) and EVP-6124 (1.0 mg/day) in people with Alzheimer's Disease and Central Nervous System Diseases, run by FORUM Pharmaceuticals Inc at 4 sites 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 3 inclusion and 6 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 20 Apr 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites 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 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.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Jul 2011). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Safety and Tolerability of Multiple Doses of EVP-6124 or Placebo in Subjects With Alzheimer's Disease (time frame: Pre-treatment (Day -2) [or screening for physical examination] to Day 28 [or Day 35, for AEs only]). 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 20 Apr 2012.
