About this study
Official title: A Phase I Clinical Trial to Evaluate the Safety and Immunogenicity of a Clade B Gag DNA/PLG and Env DNA/PLG Microparticles Vaccine and a Clade B Recombinant, Oligomeric gp140/MF59 Adjuvant Vaccine in Healthy, HIV-1 Uninfected Adult Participants
To prevent HIV infection, a vaccine that produces strong HIV-specific humoral (B-cell) and cellular (T-cell) immune system responses is desirable. The purpose of this study is to test the safety of and immune response to a novel combination HIV vaccine in HIV uninfected adults. This study will also test the safety of and immune response to a protein vaccine given alone.
Read the detailed description
The development of a vaccine eliciting HIV-specific humoral and cellular immune responses is desirable for the prevention of HIV infection. This study will investigate a combination vaccine regimen consisting of priming with DNA followed by boosting with a recombinant envelope glycoprotein adjuvanted in MF59.
All participants will be followed for 15 months. Participants enrolled in Groups 1, 2, 3, and 4 will receive either the vaccine or placebo. Study visits will be completed at initial entry; five visits every 14 days for the first 2.5 months; and visits at Months 4, 4.5, 6, 6.5, 9, 9.5, 12, and 15. All participants will undergo physical exams, urine collection, and blood tests to assess safety, HIV infection, and immune responses to injections. Risk reduction/pregnancy prevention counseling will be given at every study visit. Participants will also be asked to complete questionnaires about outside testing and beliefs at certain visits.
There are two parts to this study. In Part A, participants will be sequentially assigned to one of three groups. Each group will receive injections of different amounts of either DNA vaccine or placebo at entry, Month 1, and Month 2. This is followed by identical injections of glycoprotein/adjuvant or placebo at Months 6 and 9. Group 1 will receive 250 mcg each of the gag and env DNA plasmid with microparticle vaccine; Group 2 will receive 500 mcg of each vaccine; Group 3 will receive 1000 mcg of each vaccine. Participants will be enrolled sequentially from low to high dose beginning with Group 1.
In Part B, Group 4 will begin the second part of the study simultaneously after safety review of all participants in Part A. Group 4 participants will receive identical injections of either DNA vaccine or placebo at entry and at Months 1, 2, 6, and 9.
Group 5 will begin enrollment after enrollment is completed for Groups 1, 2, 3, and 4. Group 5 participants will receive identical injections of either glycoprotein/adjuvant or placebo at study entry and at Months 3 and 9. There will be 11 study visits for Group 5 participants; they will occur at screening, study entry, and Months 0.5, 2, 3, 3.5, 6, 9, 9.5, 12, and 15. A physical exam and risk reduction/pregnancy prevention counseling will occur at all visits; participants will be asked at every visit about any adverse events they may have experienced. Blood and urine collection will occur at selected visits. Participants will be also asked to complete questionnaires about outside testing and beliefs at certain visits.

All participants will undergo physical exams, urine collection, and blood tests to assess safety, HIV infection, and immune responses to injections. Risk reduction/pregnancy prevention counseling will be given at every study visit. Participants will also be asked to complete questionnaires about outside testing and beliefs at certain visits.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Clade B gag DNA/PLG and env DNA/PLG Microparticles and Clade B Recombinant, Oligomeric gp140/MF59 Adjuvant in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 4 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 7 inclusion and 23 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 4 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 (local and systemic reactogenicity signs and symptoms, laboratory measures, and adverse and serious experiences). The study lists 3 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 NCT00073216, 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.
