About this study

Official title: A Pilot Study to Investigate the Safety and Immunogenicity of a Peptide Vaccine for HIV Infected HLA-A2 Individuals Designed to Impede the Development of Antiretroviral Resistance

RATIONALE: Vaccines made from peptides may help the body build an effective immune response. Incomplete Freund's adjuvant may stimulate the immune system in different ways and may help the vaccine work better. Colony-stimulating factors, such as GM-CSF, may increase the number of immune cells found in bone marrow or peripheral blood. Giving vaccine therapy together with incomplete Freund's adjuvant and GM-CSF may be an effective treatment for patients with HIV.

PURPOSE: This clinical trial is studying how well giving vaccine therapy together with incomplete Freund's adjuvant and GM-CSF works in treating patients with HIV.

Read the detailed description

OBJECTIVES:

Primary

  • Assess the safety of vaccination comprising E1M184V peptide with incomplete Freund's adjuvant in combination with sargramostim (GM-CSF) in patients with HIV who are HLA-A2 positive.
  • Assess, preliminarily, the ability of E1M184V peptide vaccine to induce a cytotoxic T-cell response, defined by ELISPOT assay, in these patients.

Secondary

  • Explore, preliminarily, the effect of this regimen on HIV viral load and CD4 count in these patients.
  • Explore, preliminarily, the development of lamivudine or emtricitabine resistance in patients who subsequently receive lamivudine or emtricitabine.
  • Explore, preliminarily, the ability of E1M184V peptide vaccine to induce a cytotoxic T-cell response as assessed by HLA-A2 class I tetramers and intracellular interferon gamma production after stimulation with E1M184V.

OUTLINE: This is a pilot study.

Patients receive vaccination comprising E1M184V peptide and incomplete Freund's adjuvant subcutaneously (SC) on day 1 in weeks 0, 4, 8, 12, and 16. Patients also receive sargramostim (GM-CSF) SC immediately after vaccination and once daily on days 1-4. Some patients do not receive GM-CSF after the first 2 doses of vaccine. Treatment continues in the absence of unacceptable toxicity.

Patients undergo blood collection at baseline and at 4, 12, 20, 36, and 52 weeks for biomarker/laboratory analysis. Assays may include immunoenzyme techniques and viral genotyping.

After completion of study treatment, patients are followed periodically for up to 2 years.

PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study.

What is being measured

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

  1. Impact of treatment on immune response, in terms of the difference between cytotoxic T-lymphocyte effector frequency, as measured by enzyme-linked immunospot (ELISPOT) at baseline and at week 20

Secondary outcomes (3)
  1. Effects of treatment on viral load

  2. Sequencing of any resultant HIV strains

  3. CD4 counts for assessment of effects on HIV disease

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing E1M184V peptide vaccine, incomplete Freund's adjuvant and sargramostim in people with Nonneoplastic Condition, run by National Institutes of Health Clinical Center (CC) 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 2 May 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?

Impact of treatment on immune response, in terms of the difference between cytotoxic T-lymphocyte effector frequency, as measured by enzyme-linked immunospot (ELISPOT) at baseline and at week 20. 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 2 May 2012.
