HIV InfectionsPhase 1NCT00000632
A Phase I Clinical Trial to Evaluate the Safety and Immunogenicity of 100 mcg of Env 2-3 in MF59
A Phase 1 study testing Env 2-3 in people with HIV Infections and HIV Seronegativity, run by National Institute of Allergy and Infectious Diseases (NIAID) at 3 sites in United States.
Trial summary
To evaluate the safety and immune response of 100 mcg Env 2-3 antigen administered on days 0, 30, 180, and 365. Preliminary immunologic data from protocol VEU 005B show evidence of the development of functional antibodies in the form of increased peptide binding and development of neutralizing antibodies.

About this study
To evaluate the safety and immune response of 100 mcg Env 2-3 antigen administered on days 0, 30, 180, and 365.
Preliminary immunologic data from protocol VEU 005B show evidence of the development of functional antibodies in the form of increased peptide binding and development of neutralizing antibodies. Evaluation of an antigen dose having potentially greater immunogenicity is therefore of particular interest.

Twelve healthy volunteers receive injections of 100 mcg Env 2-3 in MF59 emulsion and two volunteers receive MF59 only on days 0, 30, 180, and 365. Follow-up continues for 6 months after the last injection.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Env 2-3 in people with HIV Infections and HIV Seronegativity, 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 2 inclusion and 15 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 2 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 NCT00000632, 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 2 Nov 2021.
