Summary:

      Background:

      Human immunodeficiency virus (HIV) is a global health threat. The body uses antibodies to
      fight infection. VRC07-523LS is an antibody directed against HIV. It may be used to prevent
      mother-to-child transmission of HIV. It may also prevent sexual transmission of HIV and treat
      HIV-1 infected people.

      Objective:

      To test the safety, tolerability, dose, and pharmacokinetics of VRC07-523LS in healthy
      adults.

      Eligibility:

      Healthy people ages 18-50

      Design:

      Participants will be screened with:

      Medical history

      Physical exam

      Blood and urine tests

      Participants will be assigned to 1 of 7 groups:

      Groups 1-5 will get the drug at 1 visit and then be observed for 24 weeks.

      Groups 6 and 7 will get the drug at 1 visit every 12 weeks, for a total of 3 doses over 48
      weeks.

      Participants will get the drug in 1 of 2 ways:

      Infusion into a vein over at least 30 minutes. Participants will have blood tests 1, 3, and 6
      hours after the infusion. They will have 1-3 visits during that week. Those in Group 7 will
      have 4-5 visits in the week after their second and third doses.

      Injection into the fatty tissue under the skin. Participants will have blood tests before the
      injection. They will have 1-3 visits during that week. Those in Group 6 will have 4-5 visits
      after the second and third doses.

      Visits include:

      Physical exam

      Blood and urine tests

      Optional oral swabs to collect saliva

      Participants will keep a diary of their temperature and symptoms for 3 days after each dose.
