What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants Who Experienced at Least One Adverse Event

    An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product.

    Measured: Up to 4 years after first dose of vaccine

  2. Number of Participants Who Discontinued Study Drug Due to an Adverse Event

    This is a measure of the number of participants who discontinued study drug because of an adverse event. An adverse event is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product.

    Measured: Up to 6 months after first dose of vaccine

  3. Geometric Mean Titer (GMT) of Amyloid Beta (Aβ) Peptide 1-40 Specific Antibodies at Month 7

    The level of Aβ Peptide 1-40 specific antibodies was measured as the geometric mean titer (GMT) one month after the third dose (Month 7) of vaccine using an enzyme-linked immunosorbent assay (ELISA).

    Measured: Month 7

  4. Mean Fold Change From Baseline in GMT of Aβ Peptide 1-40 Specific Antibodies

    The Aβ Peptide 1-40 specific immunogenicity of 3-dose regimen of V950 was measured one month after the third dose (Month 7) of vaccine by the GMT fold change of Aβ 1-40 specific antibodies compared to Baseline (Month 0) using ELISA.

    Measured: Baseline and Month 7

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing V950 and ISCOMATRIX™ in people with Alzheimer Disease, run by Merck Sharp & Dohme LLC.

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 5 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 25 Sep 2015. 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 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 18 Dec 2012). 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?

Number of Participants Who Experienced at Least One Adverse Event (time frame: Up to 4 years after first dose of vaccine). The study lists 4 primary outcomes in all. 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 25 Sep 2015.
