What this trial studies

This phase II study investigates the immunogenicity of the Shingrix vaccine in patients who have undergone allogeneic hematopoietic stem cell transplantation. Following transplantation, patients experience compromised immunity, increasing their risk of developing shingles. The study aims to assess the vaccine's effectiveness and safety in this population, comparing results to historical data from patients who received autologous transplants. The goal is to provide insights into the vaccine's potential to prevent shingles in these high-risk individuals.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who are between 12 to 36 months post-allogeneic stem cell transplant.

Not a fit: Patients who have experienced shingles after their transplant or are currently pregnant may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could significantly reduce the incidence of shingles in patients who have undergone allogeneic stem cell transplantation.

How similar studies have performed: Previous studies have shown the Shingrix vaccine to be safe in allogeneic transplant recipients, but this study aims to provide more comprehensive data on its immunogenicity in this specific population.

Eligibility criteria

Inclusion Criteria:

* Age ≥18 years
* ≥ 12 months and ≤ 36 months post-AlloSCT
* Donor sources: matched related, matched unrelated, cord blood
* Any malignant hematological disease including acute leukemia, myelodysplastic syndrome, non-Hodgkin's lymphoma, Hodgkin's lymphoma, chronic lymphocytic leukemia, chronic myeloid leukemia, multiple myeloma, and myeloproliferative disorders.
* Any conditioning regimen
* Any planned immunosuppressive prophylactic regimen
* Patients with chronic graft-versus-host disease on stable immunosuppression
* Ability to understand and the willingness to sign a written informed consent.
* Negative pregnancy test in female patients of childbearing potential

Exclusion Criteria:

* Patients who had zoster after an allogeneic transplant and prior to enrollment
* Patients who are currently pregnant
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to the recombinant zoster vaccine, Shingrix, or other agents used in study.
* Patients who have had a relapse of their primary hematological disease
* Previous allogeneic stem cell transplantation
* Acute disease at the time of vaccination
* Thrombocytopenia that in the judgment of the investigator would make intramuscular injection unsafe.
