About this study

Official title: A Phase I Clinical Trial to Evaluate the Safety and Immunogenicity of the Recombinant Protein Vaccine EP-1043 and the DNA Vaccine EP HIV-1090 Given Alone or in Combination in Healthy, HIV-1-Uninfected Adult Participants

The purpose of the study is to determine the safety of and immune response to the investigational HIV vaccine, EP HIV-1090, in HIV uninfected adults.

Read the detailed description

The worldwide HIV/AIDS epidemic may only be controlled through the development of a safe and effective vaccine that will prevent HIV infection. DNA vaccines are inexpensive to construct, readily produced in large quantities, and stable for long periods of time. EP HIV-1090 is a DNA HIV CTL vaccine; the proteins for which its genes code are designed to interact with CD8 cells (CTL) and cause CD8 cell proliferation. The DNA plasmids in EP HIV-1090 code for proteins conserved among HIV subtypes A, B, C, D, F, and G, which encompass the HLA subtypes of 85% of the worldwide general population.

Participants will be enrolled in this study for 1 year. Group 4 participants will receive EP HIV-1090 or placebo at study entry and Months 1, 3, and 6. There will be 11 study visits that will occur at screening; study entry; and Months 0.5, 1, 1.5, 3, 3.5, 6, 6.5, 9, and 12. A physical exam and risk reduction/pregnancy prevention counseling will occur at each visit. Participants will be asked about their adverse experiences from vaccination at each visit. Blood and urine collection will occur at selected visits.

What is being measured

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

  1. Safety as assessed by local and systemic reactogenicity signs and symptoms, laboratory measures, and adverse and serious experiences

    Measured: After each injection and for 12 months following the first injection

Secondary outcomes (2)
  1. Immunogenicity as assessed by HIV-specific cellular responses assessed by interferon-gamma ELISpot assays and intracellular cytokine staining

    Measured: Throughout the study

  2. Social impacts as assessed by negative experiences or problems reported by the participants

    Measured: Throughout the study

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing EP HIV-1043 and EP HIV-1090 in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 3 sites 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 6 inclusion and 28 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 14 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites 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 as assessed by local and systemic reactogenicity signs and symptoms, laboratory measures, and adverse and serious experiences (time frame: After each injection and for 12 months following the first injection). 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 NCT00141024, which also lists 6 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 14 Oct 2021.
