Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 to 50 years
  • All sexes

Who may be able to join

  • Patients must be:
  • Healthy HIV-seropositive adults (generalized lymphadenopathy, seborrheic dermatitis acceptable).

Who cannot join

  • Co-existing Condition:
  • Patients with the following conditions or symptoms are excluded:

  • Evidence of an AIDS defining opportunistic infection.
  • Prior Medication:
  • Excluded:
Show all 16Show fewer
  • Any potential immunomodulating agents (e.g., isoprinosine, imuthiol, lithium) within 90 days of screening.
  • Immunosuppressive medications during the past 3 months.

About this study

To determine the safety and immunogenicity of Env 2-3 in combination with MTP-PE/MF59 adjuvant in adult volunteers with HIV infection.

By vaccinating those who have HIV infection, perhaps the replication (reproduction) of existing viral strains can be suppressed and the asymptomatic period early in the infectious process can be prolonged. One potential way to do this is to boost HIV antigen-specific CD4 responses, which may in turn increase the effectiveness of CD8 killing of HIV infected cells.

By vaccinating those who have HIV infection, perhaps the replication (reproduction) of existing viral strains can be suppressed and the asymptomatic period early in the infectious process can be prolonged. One potential way to do this is to boost HIV antigen-specific CD4 responses, which may in turn increase the effectiveness of CD8 killing of HIV infected cells.

Eight patients are entered in the pilot portion of the study, thirty patients are entered on Part A and fifteen patients are entered on Part B. In the pilot study, patients receive 30 mcg Env 2-3 vaccine plus 0 - 10 mcg MTP-PE/MF59 adjuvant. Patients on Part A receive one of the following: MF59 emulsion only; 100 mcg MTP-PE/MF59 only; 30 mcg Env 2-3 with MF59 emulsion only; or 30 mcg Env 2-3 vaccine with 100 mcg MTP-PE/MF59. Patients on Part B receive either 100 mcg MTP-PE/MF59 only or 30 mcg Env 2-3 vaccine plus 100 mcg MTP-PE/MF59. Treatment is administered on days 0, 28, and 112, and patients are followed for up to 10 months. Per amendment, patients may receive two additional doses of 30 mcg Env 2-3 or placebo in MTP-PE/MF59 at 7 and 10 months (Parts A and B) or 9 and 12 months (Pilot study) after their initial inoculation.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing MTP-PE/MF59 and Env 2-3 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 6 inclusion and 16 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 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.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000958, 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; AzTrials last refreshed its copy on 5 Nov 2026.
