PRIMARY outcome

Timeframe: Measured through 7 days after each vaccine dose at Months (0,2,6,12)

Graded according to the Division of AIDS (DAIDS) Table for Grading the Severity of Adult and Pediatric Adverse Events, Version 2.1 \[July 2017\]. The following symptoms are considered as systemic reactogenicity if the onset date was within the periods of assessment specified in the protocol: malaise and/or fatigue, myalgia, headache, nausea, vomiting, chills, arthralgia, and body temperature. The item Max. Systemic Symptoms is the maximum of the individual systemic reactogenicities excluding body temperature for a participant.

PRIMARY outcome

Timeframe: Measured during screening, Days 14, 70, 182

Population: Overall Number of Participants Analyzed represents participants enrolled and eligible for laboratory assessment. Participants do not have laboratory assessments if they attended the visit but laboratory specimens were not collected, missed the scheduled visit, or terminated participation in the study prior to the scheduled visit.

For each local laboratory measure, summary statistics were presented by treatment group and timepoint for the overall population.

Timeframe: Measured during screening, Days 14, 70, 182

Population: Overall Number of Participants Analyzed represents participants enrolled and eligible for laboratory assessment. Participants do not have laboratory assessments if they attended the visit but laboratory specimens were not collected, missed the scheduled visit, or terminated participation in the study prior to the scheduled visit.

For each local laboratory measure, summary statistics were presented by treatment group and timepoint for the overall population.

PRIMARY outcome

Timeframe: Measured at Month 2.5(V5) and Month 6.5(V7)

Population: Avaiable Data at V5 and V7

Serum HIV-1-specific IgG responses against antigens listed below were on a Bio-Plex instrument (Bio-Rad) using a standardized custom HIV-1 Luminex assay, run at 1:50 dilution. The readout was background-subtracted mean fluorescence intensity (MFI), where background referred to a plate level control. For each sample, response magnitude is net MFI, defined as experimental antigen minus reference antigen MFI. Net MFI below 1 is set to 1, and Net MFI above 22,000 is set to 22,000. Samples from post-baseline visits have positive responses if they meet three criteria: (1) net MFI \>= antigen-specific threshold (defined as the maximum of 100 and the 95th percentile of baseline net MFI), (2) net MFI \> 3 times baseline net MFI, and (3) experimental antigen MFI \> 3 times baseline MFI. Data are excluded if the blood draw date was outside the allowable window, a participant was HIV-infected, or the reference antigen exceeds 6500 MFI.

SECONDARY outcome

Timeframe: Measured at Month 2.5(V5) and Month 6.5(V7)

Population: Avaiable Data at V5 and V7

Neutralizing antibodies against HIV-1 were measured as a function of reductions in Tat-regulated luciferase (Luc) reporter gene expression in TZM-bl and TZM-bl/Fcg RI cells . Assays in both cell lines measured neutralization titers as a function of a reduction in Tat-induced luciferase reporter gene expression after a single round of infection with Env-pseudotyped viruses. Test samples were assayed against a panel of HIV-1 strains that exhibit heightened susceptible to neutralization by MPER bnAbs in TZM-bl/Fcg RI cells.

SECONDARY outcome

Timeframe: Measured at Month 2.5(V5) and Month 6.5(V7)

Population: Avaiable Data at V5 and V7

Neutralizing antibodies against HIV-1 were measured as a function of reductions in Tat-regulated luciferase (Luc) reporter gene expression in TZM-bl and TZM-bl/Fcg RI cells . Assays in both cell lines measured neutralization titers as a function of a reduction in Tat-induced luciferase reporter gene expression after a single round of infection with Env-pseudotyped viruses. Test samples were assayed against a panel of HIV-1 strains that exhibit heightened susceptible to neutralization by MPER bnAbs in TZM-bl/Fcg RI cells.
