About this study

The investigators plan to study the immunogenicity of the vaccine before and after lung transplantation. Patients (at least 50 years old) before and after lung transplantation will be enrolled. The investigators hypothesize that the recombinant varicella-zoster subunit vaccine is able to induce cellular immunogenicity after transplantation.

Read the detailed description

Solid organ transplant recipients receive lifelong immunosuppression and are at increased risk for reactivation of all herpesviruses including VZV. Epidemiologic studies show the cumulative incidence in lung transplant recipients of reactivation to be 15-20%. A non-live, recombinant subunit vaccine (Shingrix; GSK vaccines) was recently licensed for the prevention of shingles in people aged 50 years or older. The investigators plan to study the immunogenicity of the vaccine before and after lung transplantation. Patients (at least 50 years old) before and after lung transplantation will be enrolled. The investigators hypothesize that the recombinant varicella-zoster subunit vaccine is able to induce cellular immunogenicity after transplantation.

What is being measured

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

  1. Cellular immunity to varicella zoster induced by varicella zoster subunit vaccine.

    Cellular immunogenicity against VZV induced by varicella zoster subunit vaccine in lung transplant recipients measured as a percentage of CD4+ and CD8+ T-cells measured by intracellular flow-cytometry based staining. The cellular immunogenicity of the vaccine in lung transplant recipients will be compared to the control group (pre-transplant vaccination).

    Measured: 4 weeks after second dose of vaccine

Secondary outcomes (2)
  1. Humoral immunogenicity to varicella zoster induced by varicella zoster subunit vaccine in lung transplant recipients.

    Humoral immunogenicity (increase of GMTs of anti-VZV antibodies) in lung transplant

    Measured: 4 weeks after second dose of vaccine

  2. Humoral immunogenicity to varicella zoster induced by varicella zoster subunit vaccine in post-transplant group vs. pre-transplant group

    Humoral immunogenicity (GMTs of anti-VZV antibodies compared pre and post vaccination) against VZV induced by varicella zoster subunit vaccine in lung transplant recipients compared to the pre-transplant control group.

    Measured: 4 weeks after second dose of vaccine

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing VZV subunit vaccine in people with Varicella Zoster Vaccine, run by Deepali Kumar at 1 site in Canada.

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 4 inclusion and 10 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: status not confirmed, as of the sponsor's last update on 19 Oct 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Canada. 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. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Results are not available in the source record.

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?

Cellular immunity to varicella zoster induced by varicella zoster subunit vaccine. (time frame: 4 weeks after second dose of vaccine). 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 19 Oct 2020.
