Summary

The purpose of this study is to evaluate the safety, tolerability, and serum concentrations of a human monoclonal antibody, VRC-HIVMAB075-00-AB (VRC07-523LS), administered in multiple doses and routes to healthy, HIV-uninfected adults.

Detailed description

This study will evaluate the safety, tolerability, and serum concentrations of a human monoclonal antibody, VRC-HIVMAB075-00-AB (VRC07-523LS), administered in multiple doses and routes to healthy, HIV-uninfected adults. Participants will be randomly assigned to one of six groups. Participants in Group 1 will receive 2.5 mg/kg of VRC07-523LS by intravenous (IV) infusion at Weeks 0, 16, 32, 48, and 64. Participants in Group 2 will receive 5 mg/kg of VRC07-523LS by IV infusion at Weeks 0, 16, 32, 48, and 64. Participants in Group 3 will receive 20 mg/kg of VRC07-523LS by IV infusion at Weeks 0, 16, 32, 48, and 64. Participants in Group 4 will receive 2.5 mg/kg of VRC07-523LS by subcutaneous (SC) injection at Weeks 0, 16, 32, 48, and 64. Participants in Group 5 will receive 5 mg/kg of VRC07-523LS by SC injection at Weeks 0, 16, 32, 48, and 64. Participants in Group 6 will receive 2.5 mg/kg of VRC07-523LS or placebo by intramuscular (IM) injection at Weeks 0, 16, 32, 48, and 64. Participants will attend numerous study visits throughout the course of the study, beginning at Week 0 through Week 112. Visits may include physical examinations, blood and urine collection, HIV testing, risk reduction counseling, and questionnaires.
