What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Comparator: Varicella Zoster Virus VaccineBiological

    Single 0.65 mL subcutaneous injection of higher potency zoster vaccine (~207,000 plaque-forming units [PFU]/0.65-mL dose)

  • Comparator: Varicella Zoster Virus VaccineBiological

    Single 0.65 mL subcutaneous injection of lower potency zoster vaccine (~58,000 plaque-forming units [PFU]/0.65-mL dose)

What is being measured

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

  1. Number of Participants With Vaccine-related Serious Clinical Adverse Experiences (SAEs)

    The incidence of vaccine-related SAEs occurring Day 1 through Day 42 postvaccination. Whether a serious clinical adverse experience occurring Day 1 through Day 42 postvaccination was vaccine-related was determined by the investigator who was a qualified physician . The difference in the risk of developing a vaccine-related SAE between the two groups was compared at the 2-sided 0.05 level.

    Measured: Day 1-42 post vaccination

  2. Number of Participants With Moderate or Severe Injection-site Pain/Tenderness/Soreness or Swelling (> 2 Inches at Largest Diameter)

    Measured: Day 1-5 postvaccination

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Comparator: Varicella Zoster Virus Vaccine in people with Healthy, 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 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 7 Oct 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 10 Jun 2010). 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 With Vaccine-related Serious Clinical Adverse Experiences (SAEs) (time frame: Day 1-42 post vaccination). 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 NCT00092417, 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 7 Oct 2015.
