Brief Summary:
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.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. 1. Proportion of participants with solicited and treatment-related unsolicited adverse events and their duration. [ Time Frame: 92 Weeks ]
  2. Proportion of participants with serious adverse events (SAEs) throughout the study period that are considered related to investigational product and their duration. [ Time Frame: 92 Weeks ]
  3. Serum concentration of each antibody in each group at multiple timepoints along with participant characteristics (e.g. sex, weight, and BMI) [ Time Frame: 92 Weeks ]
  4. The ratio of 3BNC117-LS-J to 10-1074-LS-J that, when injected SC, will maintain similar levels of each bNAb at steady state. [ Time Frame: 92 Weeks ]

Secondary Outcome Measures :
  1. Serum concentration of anti-3BNC117-LS-J antibodies in each group at multiple timepoints. [ Time Frame: 92 Weeks ]

  • Any clinically significant acute or chronic medical condition that is considered progressive or in the opinion of the investigator makes the participant unsuitable for participation in the study
  • Infectious disease diagnosis: Hepatitis B infection as measured by HbsAg and/or PCR, Hepatitis C infection (US: HCV RNA positive, or interferon-alpha treatment for hepatitis C infection in the past year, or interferon-alpha-free treatment for hepatitis C infection completed in the past 6 months; Africa: HCV Ab positive and/or PCR positive), active syphilis (positive RPR confirmed by TPHA)
