About this study

Official title: A Phase 1b Randomized Double-Blind Clinical Trial to Examine Whether Polytopic Administration of VRC rAd5 Gag-pol/Env A/B/C Vaccine Enhances HIV-Specific Cellular Immune Responses in Humans

The purpose of this study is to evaluate the immune response to the Vaccine Research Center (VRC) rAd5 HIV vaccine when the vaccine components are administered in three different ways, in healthy, HIV-uninfected adults.

Read the detailed description

The VRC rAd5 HIV vaccine contains four different components. In this study, researchers will examine how the immune system responds to the vaccine when the four components are administered in three different ways:

  1. The vaccine dose containing all four components is given as a single injection in one arm, and placebo injections are given in the other arm and both legs.
  2. The vaccine dose containing all four components is divided into fourths, and one-fourth of the full dose is given in each arm and leg.
  3. The four vaccine components are separated, and a different component is given in each arm and leg.

This study will enroll healthy, HIV-uninfected adults. Participants will be randomly assigned to one of three groups. Group 1 will receive the entire dose of vaccine in their right arm and placebo vaccine in the other arm and both legs. Group 2 will receive all four different components of the vaccine, given separately as a different component per each arm and leg. Group 3 will receive the entire vaccine dose divided into fourths, with one fourth of the full dose given in each arm and leg.

At a baseline study visit, participants will undergo a physical examination and a medical and medication history review. Female participants will also take a pregnancy test. Participants will complete questionnaires and receive counseling on HIV risk reduction and pregnancy prevention. All participants will then receive vaccine given as four injections-one each in their right arm, left arm, right thigh, and left thigh (except for Group 1, placebo injections are given in left arm and both legs). After receiving the vaccine, participants will remain in the clinic for at least 30 minutes for observation and monitoring of side effects. For 7 days after the vaccination, participants will record any side effects in a symptom log; for the first 3 days after the vaccination, study staff will call participants to ensure they are completing the symptom log. Follow-up visits will occur at Months 1, 4, and 7. These visits will include the baseline study procedures and a blood collection. Participants will be contacted by study researchers once a year for 5 years for follow-up health monitoring. Blood collected during study visits will be saved for future testing.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing VRC rAd5 vaccine (rAd5 gag-pol/env A/B/C), rAd5 env A and rAd5 env B in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 8 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 24 inclusion and 32 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 15 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 8 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?

Number of recognized epitopes as measured by enzyme-linked immunospot (ELISpot) (time frame: Measured at 4 weeks following vaccination). 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 NCT01479296, 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 15 Oct 2021; AzTrials last refreshed its copy on 6 Nov 2026.
