About this study

Official title: A Phase 1-2 Randomized, Double-blind, Placebo-controlled Clinical Trial of Clade C ALVAC-HIV (vCP2438) and Bivalent Subtype C gp120/MF59® in HIV-uninfected Adults at Low Risk of HIV Infection

The HIV Vaccine Trials Network (HVTN) is doing a study to test a new HIV vaccine combination. HIV is the virus that causes AIDS.

252 people are taking part in this study at multiple sites. The US National Institutes of Health (NIH) is paying for the study.

The investigators are doing this study to answer several questions.

  • Are the study vaccines safe to give to people?
  • Are people able to take the study vaccines without becoming too uncomfortable?
  • How do people's immune systems respond to the study vaccines? (Your immune system protects you from disease.)
Read the detailed description

The HIV Vaccine Trials Network (HVTN) is doing a study to test a new HIV vaccine combination. HIV is the virus that causes AIDS. The investigators are doing this study to answer several questions:

  • Are the study vaccines safe to give to people?
  • Are people able to take the study vaccines without becoming too uncomfortable?
  • How do people's immune systems respond to the study vaccines? (Your immune system protects you from disease.)

The study uses 2 different vaccines: ALVAC-HIV (vCP2438) and bivalent gp120/MF59. These are experimental HIV vaccines -- the investigators do not know whether the vaccines will be safe to use in people, or whether they will work to prevent HIV infection. These vaccines are used only in research studies.

The ALVAC vaccine is made out of canarypox virus, which infects birds but cannot grow in human cells. This virus has small bits of man-made DNA inserted into it. DNA is a natural substance found in all living things, including people and some viruses. The canarypox virus helps get the DNA into the body's cells. The DNA then tells those cells to make small amounts of proteins that look like some of the ones found in HIV.

A study in South Africa, HVTN 097, gave a similar ALVAC vaccine to about 80 participants. So far, no one has had serious health problems.

The Protein vaccine has man-made pieces of a protein found on the outside of HIV. These protein pieces are mixed with an adjuvant called MF59. An adjuvant is something added to the vaccine to help the immune system respond better. MF59 has been included with other vaccines that have been given to over 50,000 people in clinical trials without causing any serious health problems.

This combination of study vaccines has not been given to people before. However, similar ALVAC and protein vaccines have been given to more than 10,000 people in clinical trials without causing any serious health problems. Also, over 300 people have received a similar combination of ALVAC and protein vaccines with the MF59 adjuvant in clinical trials without having any serious health problems.

The study is in 2 parts, Part A and Part B. Part B continues the study in order to learn how well boosting the study vaccines improves immune responses. 252 people took part in Part A of this study at multiple sites. Those who continue to meet eligibility requirements are invited to continue in Part B.

The US National Institutes of Health (NIH) is paying for the study. For people who continue to Part B, the study requires about 23 clinic visits in 4 years.

  9. Part A: Occurrence of IgG Ab Binding to gp120 Env Proteins Contained in the Vaccine (ZM96, TV1.C, 1086.C) After the Primary Vaccine Regimen, Measured by HIV-1 Multiplex Antibody Assay

    Serum HIV-1-specific IgG responses were measured on a Bio-Plex instrument using a standardized custom Luminex assay. The readout is background-subtracted mean fluorescent intensity (MFI), with background adjustment for an antigen-specific plate level control. For each sample, response magnitude is net MFI, defined as experimental antigen MFI minus reference antigen MFI. Net MFI less than 1 is set to 1. Samples from post-enrollment visits have positive responses if they meet three conditions: (1) net MFI greater than or equal to an antigen-specific response threshold (defined as the maximum of 100 and the 95th percentile of pre-vaccination net MFI), (2) net MFI values are greater than 3 times pre-vaccination net MFI, and (3) experimental antigen MFI values are greater than 3 times pre-vaccination MFI. Data are excluded if the blood draw date was outside the allowable window, a participant was HIV-infected, or the reference antigen exceeds 5000 MFI.

    Measured: Measured at Month 6.5

  10. Part A: Level of IgG Ab Binding to gp120 Env Proteins Contained in the Vaccine (ZM96, TV1.C, 1086.C) After the Primary Vaccine Regimen, Measured by HIV-1 Multiplex Antibody Assay

The readout is background-subtracted mean fluorescent intensity (MFI), with background adjustment for an antigen-specific plate level control. For each sample, response magnitude is net MFI, defined as experimental antigen MFI minus reference antigen MFI. Net MFI less than 1 is set to 1. The measure unit fluorescence units are relative to assay background, not relative to the placebo arm. Background is used here rather than negative control stimulation, since the antigens are used as bead coating rather than stimulation.

    Measured: Measured at Month 6.5

  13. Part A: Occurrence of CD4+ T Cell Responses to the HIV Proteins Included in the Vaccine After the Primary Vaccine Regimen. Measured by Flow Cytometry.

    PBMC samples are stimulated with synthetic peptide pools or left unstimulated as a negative control. For each sample, T-cell subset, and peptide pool, response magnitude is % cells expressing markers after peptide stimulation minus % cells expressing markers after no stimulation. A contingency table is constructed to assess response: stimulation (peptide/none) vs. marker expression (yes/no). A one-sided Fisher's exact test is applied, testing if the number of cells positive for the marker is equal in the stimulated vs. unstimulated cells. A discrete Bonferroni adjustment is made over the peptide pools. Response is positive if p<=0.00001. Data are excluded if the blood draw date was outside the visit window, the participant was HIV-infected, PBMC viability or T-cell count were low, or negative control was high.

    Measured: Measured at Month 6.5

  14. Part A: Level of CD4+ T Cell Responses to the HIV Proteins Included in the Vaccine After the Primary Vaccine Regimen.

Samples from post-enrollment visits have positive responses if they meet three conditions: (1) net MFI greater than or equal to an antigen-specific response threshold (defined as the maximum of 100 and the 95th percentile of pre-vaccination net MFI), (2) net MFI values are greater than 3 times pre-vaccination net MFI, and (3) experimental antigen MFI values are greater than 3 times pre-vaccination MFI. Data are excluded if the blood draw date was outside the allowable window, a participant was HIV-infected, or the reference antigen exceeds 5000 MFI.

    Measured: Measured at Month 6.5 and 12.5

  4. Part A: Compare the Level of IgG Ab Binding to gp120 Env Proteins Contained in the Vaccine (ZM96, TV1.C, 1086.C) After the Fourth Versus the Fifth Vaccination

    Serum HIV-1-specific IgG responses were measured on a Bio-Plex instrument using a standardized custom Luminex assay. The readout is background-subtracted mean fluorescent intensity (MFI), with background adjustment for an antigen-specific plate level control. For each sample, response magnitude is net MFI, defined as experimental antigen MFI minus reference antigen MFI. Net MFI less than 1 is set to 1. The measure unit fluorescence units are relative to assay background, not relative to the placebo arm. Background is used here rather than negative control stimulation, since the antigens are used as bead coating rather than stimulation. Comparisons were performed among positive responders only (positivity criteria is described in Outcome 30).

    Measured: Measured at Month 6.5 and 12.5

  5. Part A: Compare the Occurrence of IgG Binding Antibodies to 3 V1V2-scaffolded Env Proteins After the Fourth Versus the Fifth Vaccination

    Serum HIV-1-specific IgG responses were measured on a Bio-Plex instrument using a standardized custom Luminex assay. The readout is background-subtracted mean fluorescent intensity (MFI), with background adjustment for an antigen-specific plate level control. For each sample, response magnitude is net MFI, defined as experimental antigen MFI minus reference antigen MFI. Net MFI less than 1 is set to 1.

  7. Part A: Compare the Occurrence of CD4+ T Cell Responses to the HIV Proteins Included in the Vaccine After the Fourth Versus the Fifth Vaccinations

    PBMC samples are stimulated with synthetic peptide pools or left unstimulated as a negative control. For each sample, T-cell subset, and peptide pool, response magnitude is % cells expressing markers after peptide stimulation minus % cells expressing markers after no stimulation. A contingency table is constructed to assess response: stimulation (peptide/none) vs. marker expression (yes/no). A one-sided Fisher's exact test is applied, testing if the number of cells positive for the marker is equal in the stimulated vs. unstimulated cells. A discrete Bonferroni adjustment is made over the peptide pools. Response is positive if p<=0.00001. Data are excluded if the blood draw date was outside the visit window, the participant was HIV-infected, PBMC viability or T-cell count were low, or negative control was high.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing ALVAC-HIV and Bivalent Subtype C gp120/MF59® in people with HIV Infection, run by National Institute of Allergy and Infectious Diseases (NIAID) at 5 sites in South Africa.

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 35 inclusion and 42 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 5 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 5 sites in South Africa. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined 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.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Oct 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Part A: Number of Participants Reporting Local Reactogenicity Signs and Symptoms During the Primary Vaccine Regimen (time frame: Measured through 3 days after participants' last vaccination at Month 0,1,3, and 6). The study lists 27 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 NCT02404311, 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 5 Nov 2021.
