What is being measured
The primary outcome is the main question the study is designed to answer.
Occurrence of Vaccine-induced Systemic IgG Ab Binding to the 3 gp120 Env Proteins Contained in the Vaccine Regimen (ZM96, TV1.C, and 1086.C) in Group 1 and Group 2
Serum IgG responses were measured on a Bio-Plex instrument using a standardized custom Luminex assay, run at 1:50 dilution. 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 < 1 is set to 1, and net MFI > 22,000 is set to 22,000. Data are excluded if blood draw date was outside the allowable window, a participant was HIV-infected, reference antigen > 5,000 MFI, or baseline net MFI > 6,500. Samples from post-enrollment visits have positive responses if they meet three criteria: (1) net MFI greater than or equal to an antigen-specific response threshold (defined as the maximum of 100 and the 95th percentile of baseline net MFI), (2) net MFI values are greater than 3 times baseline net MFI, and (3) experimental antigen MFI values are greater than 3 times baseline MFI.

Vaccine-induced Occurrence of CD4+ T-cells Expressing Markers in Response to HIV Proteins Included in the Vaccine
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 (IFNg and/or IL-2) 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 adjusted p-value <=0.00001. Any Env magnitude is the maximum of 1086 gp120, TV1 gp120, and Env ZM96 magnitudes. Any HIV magnitude is the sum of Any Env and LAI Gag magnitudes. Data are excluded if blood draw date was outside the visit window, participant was HIV-infected, PBMC viability or T-cell count were low, or negative control was high.
Measured: Measured at Months 6.5, 12, 12.5, and 18
Vaccine-induced Percentage of CD4+ T-cells Expressing Markers in Response to HIV Proteins Included in the Vaccine
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 (IFNg and/or IL-2) 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 adjusted p-value <=0.00001. Any Env magnitude is the maximum of 1086 gp120, TV1 gp120, and Env ZM96 magnitudes. Any HIV magnitude is the sum of Any Env and LAI Gag magnitudes. Data are excluded if blood draw date was outside the visit window, participant was HIV-infected, PBMC viability or T-cell count were low, or negative control was high.

Occurrence of Vaccine-induced Serum IgG3 Ab Binding to Env Proteins
Serum IgG3 responses were measured on a Bio-Plex instrument using a standardized custom Luminex assay, run at 1:40 dilution. 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 < 1 is set to 1, and net MFI > 22,000 is set to 22,000. Data are excluded if blood draw date was outside the allowable window, a participant was HIV-infected, reference antigen > 5,000 MFI, or baseline net MFI > 6,500. Samples from post-enrollment visits have positive responses if they meet three criteria: (1) net MFI greater than or equal to an antigen-specific response threshold (defined as the maximum of 100 and the 95th percentile of baseline net MFI), (2) net MFI values are greater than 3 times baseline net MFI, and (3) experimental antigen MFI values are greater than 3 times baseline MFI.

HIV-specific CD4+ T Cell Polyfunctionality by ICS - Functionality Scores
COMPASS uses a Bayesian hierarchical framework to model all observed functional cell subsets and select those most likely to exhibit antigen-specific responses. Cell-subset responses are quantified by posterior probabilities. The functionality score (FS) summarizes, as a single number for each participant, the proportion of antigen-specific cell subsets among all measured subsets, irrespective of degree of functionality. FS ranges from zero to one. FS will assign a higher score to participants that exhibit antigen specificity in more cell subsets irrespective of their degree of functionality.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to evaluate the safety and immune response to an HIV clade C vaccine and to an MF59- or alum-adjuvanted clade C Env protein in healthy, HIV-uninfected adults.
Detailed description
This study will evaluate the safety, tolerability, and immunogenicity to vCP2438 (an HIV clade C vaccine) and to an unadjuvanted or MF59- or alum-adjuvanted bivalent clade C gp120 in healthy, HIV-uninfected adults.
The study will enroll healthy, HIV-uninfected participants aged 18 to 40 years. Participants will be randomly assigned to one of 4 groups. [describe further]
Study visits will include a physical examination, an interview and/or questionnaire, HIV testing and HIV risk-reduction counseling, and urine and blood collection. A subset of participants will provide rectal fluid, cervical fluid, semen, or stool samples.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing ALVAC-HIV (vCP2438), Bivalent Subtype C gp120/MF59 and Bivalent Subtype C gp120 admixed with Al(OH)3 Suspension in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 6 sites in 3 countries.
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 37 inclusion and 47 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 24 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 6 sites in South Africa, Mozambique, Zimbabwe. 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 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 18 Feb 2021). 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?
Occurrence of Vaccine-induced Systemic IgG Ab Binding to the 3 gp120 Env Proteins Contained in the Vaccine Regimen (ZM96, TV1.C, and 1086.C) in Group 1 and Group 2 (time frame: Measured at Month 6.5). The study lists 20 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 NCT03284710, 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 24 Jul 2026.
