Read the detailed description

This study will evaluate the safety and tolerability of an HIV-1 nef/tat/vif, env pDNA vaccine delivered with EP, followed by a rVSV HIV envC vaccine boost, in healthy, HIV-uninfected adults.

Participants will be randomly assigned to one of two groups. Participants in Group 1 will receive the HIV-1 nef/tat/vif, env pDNA vaccine at Day 0 and Months 1 and 3, followed by the rVSV HIV envC vaccine boost at Months 6 and 9. Participants in Group 2 will receive placebo vaccine at Day 0 and Months 1, 3, 6, and 9. Study visits will occur at Day 0, Week 2, and Months 1, 1.5, 3, 3.25, 3.5, 6, 6.25, 6.5, 9, 9.25, 9.5, 12, and 15. Visits may include physical examinations, urine collection, blood collection, HIV testing, risk reduction counseling, assessments, and questionnaires. Participants will be contacted by study staff for follow-up monitoring annually for 3 years following the initial study injection.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing HIV-1 nef/tat/vif, env pDNA vaccine and rVSV HIV envC vaccine in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 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 43 inclusion and 54 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 2 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. Some participants in this study may receive a placebo. 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?

Frequency of local injection/EP site and systemic reactogenicity signs and symptoms (time frame: Measured through Month 15). The study lists 6 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 NCT02654080, 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 15 Oct 2021.
