This is a Phase 1/2a open label study to evaluate the safety, tolerability, pharmacokinetics and anti-viral efficacy of PGT121, VRC07-523LS and PGDM1400 antibodies for HIV prevention and therapy. PGT121, VRC07-523LS and PGDM1400 are recombinant human IgG1 monoclonal antibodies that target a V3 glycan-dependent epitope region of the HIV envelope protein and the CD4 binding site (CD4bs) of the HIV envelope protein. PGT121, VRC07-523LS and PGDM1400 mAbs were chosen for this study because of their potency, their ability to neutralize a wide array of cross-clade HIV viruses in a complementary pattern, and their proven antiviral activity in animal studies, e.g., their capacity to robustly prevent and treat simian-human immunodeficiency virus (SHIV) in rhesus monkeys. The potency and breadth of PGT121, VRC07-523LS and PGDM1400 raise the possibility that monoclonal antibodies may be effective for HIV prophylaxis at low doses and against global viruses. Neutralization sensitivity profiles are complementary; and the combination of these mAbs with unique epitope specificities will provide experience assessing the potential additive, synergistic, or antagonistic properties of two bNAbs given sequentially.
