About this study

Official title: A Phase I Dose Escalation Study of Peptide Vaccines With Activity Against Human Cytomegalovirus

RATIONALE: Vaccines made from peptides may help the body build an immune response to kill cytomegalovirus.

PURPOSE: This phase I trial is studying the side effects and best dose of vaccine therapy in preventing cytomegalovirus in healthy participants.

Read the detailed description

OBJECTIVES:

Primary

  • To establish whether 3 vaccine dose levels of PADRE-CMV and tetanus-CMV fusion peptide vaccines are safe and well tolerated in healthy cytomegalovirus (CMV)-seropositive or -seronegative participants.
  • To establish safe dose levels for the PADRE-CMV and tetanus-CMV fusion peptide vaccines in combination with PF 03512676 DNA in these participants.

Secondary

  • To provide preliminary evidence of enhanced cellular immunity to CMV at levels of T cells that would support potential feasibility if such cells were to be transferred from the donor to recipients of hematopoietic stem cell transplantation (HSCT) in amounts consistent with protection against disease.
  • To determine whether a reduced dose of peptide vaccine can be immunogenic in combination with PF 03512676 DNA.
  • To confer CMV-specific cytotoxic T-lymphocyte (CTL) function to CMV-negative participants.
  • To determine the duration of immune enhancement of CMV-specific CTL function up to 12 months following immunization of healthy participants.

OUTLINE: This is a dose-escalation study of PADRE-CMV and tetanus-CMV fusion peptide vaccines. Participants are stratified according to cytomegalovirus (CMV) serum status (positive vs negative). Participants are assigned to 1 of 2 groups.

  • Group A: Participants receive either PADRE-CMV fusion peptide vaccine or tetanus-CMV fusion peptide vaccine subcutaneously (SC) on days 1, 21, 42, and 63 in the absence of unacceptable toxicity.
  • Group B: Participants receive either PADRE-CMV fusion peptide vaccine in CpG 7909 adjuvant SC or tetanus-CMV fusion peptide vaccine in CpG 7909 adjuvant SC on days 1, 21, 42, and 63 in the absence of unacceptable toxicity.

Participants are contacted by telephone every 3-7 days after immunization. Participants also complete a notebook on any health-related event for 14 days after each immunization.

Participants undergo blood sample collection at baseline and periodically during study for immunologic laboratory studies, including flow cytometry, by HLA-A2-CMV-tetramer, CMV-specific intracellular cytokine, CMV-specific CD107 degranulation, lymphoproliferation, and chromium release assays.

After completion of study therapy, participants are followed for up to 1 year.

What is being measured

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

  1. Successful completion of a series of 4 injections (at weeks 0, 3, 6, and 9) without dose-limiting toxicity

    Measured: 3 weeks after the final vaccine dose

  2. Maximum tolerated dose of each vaccine with or without adjuvant CpG 7909

    Measured: 1 year after the final vaccine dose

Secondary outcomes (1)
  1. Number of CMV-positive and CMV-specific CD8+ T cells/L

    Measured: 1 year after final vaccine dose

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PADRE-CMV fusion peptide vaccine, tetanus-CMV fusion peptide vaccine and agatolimod sodium in people with Nonneoplastic Condition, 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?

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 25 Jun 2012. 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?

Successful completion of a series of 4 injections (at weeks 0, 3, 6, and 9) without dose-limiting toxicity (time frame: 3 weeks after the final vaccine dose). The study lists 2 primary outcomes in all. 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 NCT00722839, which also lists 1 linked publication.

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 25 Jun 2012.
