About this study
To expand the safety information regarding MN rsgp 120/HIV-1 formulated with QS21 or alum. To evaluate the immunogenicity of low doses of MN rsgp 120/HIV-1 formulated with QS21 or alum.
Studies to date indicate that there may be a dose-sparing effect with the use of QS21. In animal studies, when QS21 has been employed as an adjuvant, it shifted both the dose response curve and allowed less antigen to elicit equivalent binding antibody titers to the rgp120 protein. There may also be an acceleration in the course of antibody response after both the first and the second immunizations. Although the final titers in response to vaccine given in both alum and QS21 appear similar after 3 doses in humans, this plateau may be reached more readily, and with a lower antigen dose, when using QS21 as an adjuvant. In addition, it has been established that using a lower dose of antigen may elicit an immune response which is characterized by lymphoproliferation and production of TH1-like cytokines such as INF-gamma, interleukin-2, interleukin-4, interleukin-5 and interleukin-10.

Patients will be recruited and screened and those determined as eligible will be enrolled in the study. Initially, 5 patients will be randomized into each combination of MN rsgp 120/HIV-1 dose and adjuvant, QS21 or alum, along with 2 controls for each adjuvant group. An additional 10 patients will be randomized equally between the QS21 and alum arms to the lowest dose group having 2 or more responders defined as an MN Vital Dye neutralization titer greater than or equal to 10 measured at 2 weeks after the second vaccination. 1 additional control will also be randomized to each adjuvant group. If neither dose has 2 or more responders, no additional patients will be enrolled. Patients will receive their randomly assigned injections at months 0, 1 and 6. Patients will be tested for DTH to MN rsgp 120 at 12 months.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing rgp120/HIV-1MN in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 3 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 9 inclusion and 26 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 4 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 3 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00000853, 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 4 Nov 2021.
