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.

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.

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.
