Trial summary

The purpose of the study is to determine the safety of a new HIV vaccine and to evaluate the immune response to the vaccine. Only some HIV genes are used to make the vaccine and therefore the vaccine cannot itself cause HIV or AIDS. Read more about this study

About this study

Official title: Evaluation of the Safety of a Polyvalent Vaccinia Virus HIV-1 Envelope Recombinant Vaccine (PolyEnv1) in Healthy Adults

The purpose of the study is to determine the safety of a new HIV vaccine and to evaluate the immune response to the vaccine. Only some HIV genes are used to make the vaccine and therefore the vaccine cannot itself cause HIV or AIDS.

Read the detailed description

HIV-1 presents several challenges to vaccine design, including: 1) high mutation rates resulting in tremendous diversity of virus envelope, the target of neutralizing antibody, such that antibody elicited to one envelope may not protect from virus with a distinct envelope; 2) envelope from infected persons differs from envelopes obtained from T-cell line cultures, the usual source of envelope for vaccines; and 3) envelope glycoprotein exists as oligomers on the virion surface, not as the monomers used in previous vaccines. This study will test a new vaccine that has been designed to meet these challenges by delivering diverse, patient-derived, oligomeric envelopes to induce multiple type-specific responses capable of recognizing native envelope on natural variants. The vaccine vector used in this vaccine trial is recombinant vaccinia virus based on the NYCDH vaccinia isolate.

Participants in this study will receive the PolyEnv1 HIV vaccine and will be followed for one year. Laboratory tests will be performed at 10 study visits to monitor the participants' immunologic response and assess the safety of the vaccine. Patients will also have numerous HIV tests throughout the study period.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PolyEnv1 in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) 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?

The sponsor lists 4 inclusion and 10 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 8 Jun 2011. 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?

Tolerability and safety of the PolyEnv1 vaccine (time frame: Throughout study). 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 NCT00051922, which also lists 11 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 8 Jun 2011.
