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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is an open-label, non-blinded study to assess the safety and immunogenicity of the Recombinant Zoster Vaccine (RZV) in young adult recipients of solid organ transplants (heart, liver, kidney). After obtaining consent, the patient will have pre-vaccine baseline Varicella Zoster Virus (VZV) anti-gE antibody testing performed by the Weinberg lab and then will be given first dose of vaccine. Participants will be brought back 30-60 days post-vaccine for follow up testing and second dose of vaccine. Participants will then be brought in for follow-up testing at 1-2 months, 6 months, and 12-15 months after receiving 2nd dose of vaccine. Testing for both antibody and cellular immunity to VZV will be performed throughout the study. Telephone, electronic and in-person follow up will be conducted to assess for any clinical signs of VZV reactivation, any vaccine-related side effects or any signs of acute rejection.

Phase

Phase

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.

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
Anti-glycoprotein E antibody Concentration
Time Frame: 30-60 days
Percentage of vaccinees with 4-fold rise in anti-glycoprotein E antibody concentration

Adverse Event Reporting

Percentage of vaccinees with any adverse event (AE) reported as well as those related to receipt of each dose of a 2-dose series of Recombinant Zoster Vaccine (RZV), to be analyzed within the following categories

  1. Adverse Events of Special Interests (AESI) including local reactions, clinically diagnosed rejection, or varicella disease through the end of the study period (one year post dose 2)
