Dataset from Safety and Pharmacokinetics of the Combination Broadly Neutralizing Antibodies, 3BNC117-LS-J and 10-1074-LS-J, in Healthy American and African Adults

This is a Phase 1/2 study to evaluate the safety, tolerability, and pharmacokinetics of two broadly neutralizing monoclonal human antibodies (bNAbs), 3BNC117-LS-J, which targets the CD4 binding site on HIV-1 envelope protein, and 10-1074-LS-J which targets the V3 loop of HIV-1 envelope protein. The hypothesis is that the two antibodies will be safe for healthy HIV-1 uninfected adults when co-administered subcutaneously or intravenously and, after subcutaneous administration in the optimal ratio, each antibody will maintain serum levels \>10 µg/ml for at least 3 months in HIV-uninfected participants.
