HIV InfectionsPhase 1NCT00001044
A Phase I, Multicenter, Randomized, Double-Blind, Placebo-Controlled HIV-1 Vaccine Trial to Evaluate the Safety and Immunogenicity of rgp120/HIV-1MN (Genentech) in Combination With QS21 Adjuvant and/or Alum in Healthy Adults.
A Phase 1 study testing Aluminum hydroxide, QS-21 and rgp120/HIV-1MN in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 4 sites in United States.
Trial summary
PRIMARY: To examine the safety and potential improvement in immune responses elicited by combining rsgp120/HIV-1MN with the adjuvant QS-21. SECONDARY: To examine the role of alum in the vaccine/adjuvant formulation; to determine the optimal dose ratio of vaccine to adjuvant; and to obtain initial information on the… Read more about this study

About this study
PRIMARY: To examine the safety and potential improvement in immune responses elicited by combining rsgp120/HIV-1MN with the adjuvant QS-21. SECONDARY: To examine the role of alum in the vaccine/adjuvant formulation; to determine the optimal dose ratio of vaccine to adjuvant; and to obtain initial information on the optimal schedule of administration. AS PER AMENDMENT 07/02/97: To determine the ability of immunization with rsgp120/HV-1MN in combination with QS21 with or without alum to induce an HIV-1 envelope-specific delayed-type hypersensitivity (DTH) response in volunteers who undergo rsgp120/MN skin testing.
Immune responses in HIV-uninfected individuals receiving subunit envelope vaccines formulated with alum adjuvant suggest that functional antibodies capable of neutralizing HIV-1 in vitro may be induced, but the titers are relatively low in comparison to those measured in individuals with natural HIV-1 infection. These limitations might be overcome by the addition or substitution of a more suitable adjuvant such as QS-21.

Immune responses in HIV-uninfected individuals receiving subunit envelope vaccines formulated with alum adjuvant suggest that functional antibodies capable of neutralizing HIV-1 in vitro may be induced, but the titers are relatively low in comparison to those measured in individuals with natural HIV-1 infection. These limitations might be overcome by the addition or substitution of a more suitable adjuvant such as QS-21.
Volunteers are randomized to 20 treatment arms containing four patients each. rsgp120/HIV-1MN is administered at four dose levels: 0, 100, 300, and 600 mcg, and QS-21 adjuvant is administered at three dose levels: 0, 50, and 100 mcg. Some subject cohorts receive alum in the vaccine formulation. Sixty volunteers receive injections at months 0, 1, and 10, and 20 volunteers receive injections at months 0, 1, and 6. AS PER AMENDMENT 07/02/97: All consenting volunteers who have received three immunizations will be tested for DTH response to HIV-1 envelope with use of intradermal MN rsgp120. Follow-up is extended to 56 days after administration of the intradermal injections.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Aluminum hydroxide, QS-21 and rgp120/HIV-1MN 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 5 inclusion and 21 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 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.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00001044, which also lists 2 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 4 Nov 2021.
