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.

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.

695

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.
  • Phase 3

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

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Healthy individuals 50 years of age or older with a history of chickenpox who have not had herpes zoster

Exclusion Criteria :

  • Preexisting conditions that might affect vaccine safety such as conditions that inhibit an immune response

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Vaccine-related Serious Clinical Adverse Experiences (SAEs)
Time Frame: Day 1-42 post vaccination
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.
Day 1-42 post vaccination
Number of Participants With Moderate or Severe Injection-site Pain/Tenderness/Soreness or Swelling (> 2 Inches at Largest Diameter)
Time Frame: Day 1-5 postvaccination
Day 1-5 postvaccination

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Varicella or Varicella-like Noninjection-site Rashes, Nondermatomal in Distribution With >100 Lesions
Time Frame: Day 1-42 postvaccination
Noninjection-site rash Day 1 through Day 42 postvaccination was reported by the participant to the investigator and confirmed to be varicelliform rash by the study physician and polymerase chain reaction (PCR).
Day 1-42 postvaccination
Number of Participants With Herpes Zoster (HZ) or HZ-like Rashes
Time Frame: Day 1-42 postvaccination
Noninjection-site rash Day 1 through Day 42 postvaccination was reported by the participant to the investigator and confirmed to be zosteriform rash by the study physician and polymerase chain reaction (PCR).
Day 1-42 postvaccination
Number of Participants With Fevers ≥101.0°F [≥38.3°C]
Time Frame: Day 1-21 postvaccination
Maximum reported oral or equivalent temperature ≥101.0°F [≥38.3°C] was reported Day 1 through Day 21 postvaccination.
Day 1-21 postvaccination

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
