bNAb sensitivity
bNAb sensitivity prediction was performed at screening for all participants primarily using the LabCorp–Monogram Biosciences PhenoSense HIV Monoclonal Antibody Assay on proviral HIV-1 DNA. bNAb sensitivity was a pre-specified inclusion criterion. For the PhenoSense assay, sensitivity was determined based on the concentration of bNAb required to inhibit viral replication by 90% (IC
