About this study

Official title: A Phase I Trial to Evaluate Safety and Immunogenicity of a Cytomegalovirus Peptide Vaccine Co-Injected With PF-03512676 Adjuvant in Recipients of Allogeneic Hematopoietic Stem Cell Transplant

This randomized phase I trial studies the side effects of vaccine therapy in preventing cytomegalovirus (CMV) infection in patients with hematological malignancies undergoing donor stem cell transplant. Vaccines made from a tetanus-CMV peptide or antigen may help the body build an effective immune response and prevent or delay the recurrence of CMV infection in patients undergoing donor stem cell transplant for hematological malignancies.

Read the detailed description

PRIMARY OBJECTIVES: I. To discover whether two administrations of 2.5 mg tetanus (Tet)-CMV peptide co-injected with 1 mg of PF-03512676 (tetanus-CMV fusion peptide vaccine), by subcutaneous (SC) route on days 28 and 56 post-hematopoietic cell transplantation (HCT) are safe and well tolerated in human leukocyte antigen (HLA) A*0201 CMV-positive recipients of allogeneic HCT.

SECONDARY OBJECTIVES:

  1. To measure levels of CMV-specific T cells in vaccinated compared to unvaccinated HCT recipients (control arm).

II. To assess whether vaccination of HCT recipients with Tet-CMV co-injected with PF03512676 reduces expression of programmed death 1 (PD-1) on CMV-specific T cells.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive Tet-CMV + PF03512675 SC on days 28 and 56 post-HCT.

ARM II: Patients undergo immune monitoring only.

After completion of study treatment, patients are followed up at days 70, 84, 100, 130, 160, and 180.

What is being measured

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

  1. Safety based on assessment of GVHD, graded according to the Keystone Consensus system and adverse events (AEs) based on National Cancer Institute (NCI) CTCAE version 4.03

    GVHD, local and systemic reactogenicity, and toxicity related to the vaccine formulation will be evaluated by the study principal investigator (PI), conferring with the treating physician. AEs will be summarized for each treatment group by type (MedDRA codes within organ systems), grade, and attribution.

    Measured: Up to day 180

Secondary outcomes (1)

  1. Immunogenicity evaluated by monitoring CMV-specific CD8+ T cells by multi color flow cytometric analyses

    Compare levels of CD8+ T cells binding to CMV-specific tetramers in vaccinated and unvaccinated HCT recipients by Wilcoxon rank-sum test, using integrated CMV-specific CD8+ T cells levels over the first 100 days as a numerical outcome. PD-1 expression and levels of apoptosis markers and proliferation of CMV-specific T cells immune-parameters will be compared in both arms using the Kruskall-Wallis rank-sum test.

    Measured: Up to day 180

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing tetanus-CMV fusion peptide vaccine and laboratory biomarker analysis in people with Accelerated Phase Chronic Myelogenous Leukemia and Adult Acute Lymphoblastic Leukemia in Remission, run by City of Hope Medical Center at 1 site in United States.

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 36 inclusion and 25 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 2 Apr 2024. 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 United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Safety based on assessment of GVHD, graded according to the Keystone Consensus system and adverse events (AEs) based on National Cancer Institute (NCI) CTCAE version 4.03 (time frame: Up to day 180). 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 NCT01588015, which also lists 2 linked publications.

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 2 Apr 2024.
