Inclusion criteria
Sensitivity of the viral reservoir to neutralization by 3BNC117 and 10-1074 will be tested following the screening visit (i.e. prior to enrollment and randomization). Isolated PBMCs will be analyzed using the PhenoSense HIV mAb Assay, Monogram Biosciences. The sensitivity of an individuals archieved proviruses to bNAb neutralization will be determined by the IC50 value of PBMC derived pseudovirus inhibition. Subjects that are considered sensitive to both 3BNC117 (IC90<=1.5 μg/mL) and 10-1074 (IC90<=2.0 μg/mL) AND MPI>97 AND fulfill the other inclusion/exclusion criteria will proceed to study enrolment and randomization.
If sensitivity cannot be determined by the PhenoSense HIVmAb Assay, participants will be screened for 3BNC117 and 10-1074 sensitivity using HIV env sequencing carried out in-house (Aarhus, Denmark). The method was originally established and validated by Rockefeller University that already has this method implemented. The method utilizes HIV-1 DNA envelope sequencing and a mathematical prediction binding algoritm of known binding sites of the antibodies. Based on the individual HIV env sequence, proviruses are categorized as "sensitive" or "resistant". Subjects that are determined to be sensitive to both 3BNC117 and 10-1074 (defined as at least 90% of known sequences sensitive to either bNAb) AND fulfill the other inclusion/exclusion criteria will proceed to study enrolment and randomization.
