About this study

Official title: A Phase I Randomized, Double-blind, Placebo Controlled Dose Escalation Clinical Trial to Evaluate the Safety and Immunogenicity of Recombinant Adenovirus Serotype 5 HVR48 HIV-1 Vaccine (Ad5HVR48.ENVA.01) in Healthy, HIV-1 Uninfected Adults (Ad5HVR48.ENVA.01 (rAd5HVR48) HIV-1/IPCAVD-002 Vaccine Study)

Successful control of the HIV epidemic will require a safe and effective vaccine to be developed. A successful vaccine will need to stimulate a widespread immune response. The purpose of this study is to determine the safety of and immune response to an adenovirus serotype HIV vaccine in HIV uninfected adults.

Read the detailed description

Control of the HIV pandemic can only be achieved with the development of a safe and effective preventive HIV vaccine. A vaccine that will prevent HIV infection will elicit a strong immune response from both CD4 and CD8 cells. Recombinant adenovirus serotype vectors have been shown to elicit just such a response. The purpose of this study is to determine the safety and immunogenicity of the recombinant adenovirus serotype 5 preventive HIV-1 vaccine.

This study will last 18 to 24 months. Participants will be randomly assigned to one of four arms that will receive vaccine or placebo administered via intramuscular injection. Participants in Arms 1, 2, and 3 will all receive 3 injections. Participants in Arm 4 will receive one injection. For most participants, there will be 10 study visits in this study; for participants in Arm 4, there will be only 7 visits. For Arms 1, 2, and 3, study visits will occur at baseline and on Days 0, 14, 28, 42, 56, 168, 182,196, and 365. Participants in Arms 1, 2, and 3 will receive injections on Days 0, 28, and 168. For participants in Arm 4, study visits will occur at baseline and on Days 0, 14, 28, 56, 168 and 365. Participants in Arm 4 will receive one injection only, on Day 0. Participants will be asked to record their temperature and other side effects in a symptom log for 3 days after each injection. Risk reduction/pregnancy prevention counseling and physical exams will occur at all visits. At most visits, blood, urine, and oral swab collection will occur. Samples collected will be stored for future testing. HIV testing and pregnancy testing will occur at select visits. At Years 2, 3, 4, and 5, participants will be followed-up by telephone, e-mail, or study visit to collect vital status, and information about any development of significant disability or incapacity, hospitalizations, or congenital anomalies. At these follow-up visits, blood collection will be optional.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Ad5.ENVA.48 HIV-1 vaccine 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 8 inclusion and 25 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 1 Nov 2021. 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?

Local and systemic adverse reactions (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 NCT00695877, which also lists 3 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 1 Nov 2021.
