Summary:

      Background:

      The human body uses antibodies as one way to help fight infection. VRC01LS and VRC07-523LS
      are antibodies directed against the HIV virus. Researchers want to see if they are safe and
      well tolerated. In Part A of the study, the researchers studied VRC01LS. Part A of the study
      was completed in 2017. In Part B, the researchers studied VRC07-523LS. Depending on which
      antibody received, researchers studied the amount of VRC01LS or VRC07-523LS in the body and
      how it changes over time. They evaluated the effect of antibodies on CD4+ (Cluster of
      Differentiation 4) lymphocyte count and HIV viral load, and checked to see if people who get
      VRC01LS or VRC07-523LS develop an immune response to it.

      Objective:

      To see if VRC01LS and VRC07-523LS are safe and well tolerated.

      Eligibility:

      Adults ages 18-70 who are HIV infected but otherwise healthy.

      Design:

      Participants received the study drug one time by IV infusion. A needle guided a thin tube
      into a vein. The study drug mixed with salt water was dripped into the vein over about 30
      minutes.

      Participants were monitored for 30 minutes after the infusion.

      Blood samples were taken at the following times:

        -  Once before the infusion

        -  5 times in the 4 hours after the infusion

        -  1 time 24 hours after infusion. Some participants may have had 3 optional blood draws in
           the time period between 4 and 24 hours.

      For 3 days after the infusion, participants recorded their temperature and reactogenicity
      symptoms in a diary.

      There were a total of 23 study visits over 48 weeks. Ten visits were in the first 4 weeks. At
      all visits, participants answered health questions and gave blood samples.

          3. Available for clinic visits for 48 weeks after study product administration.

          4. HIV-1 infected and clinically stable. [Note: Documented HIV-1 infection by HIV enzyme
             immunoassay (EIA) performed by a Clinical Laboratory Improvement Amendments (CLIA)
             certified outside lab within 28 days of enrollment is acceptable.]

          5. At least one plasma viral load >=500 copies/mL within 28 days of enrollment. A plasma
             viral load within 28 days and closest to the day of enrollment, that is detectable but
             not greater than 100,000 copies/mL. [Note: outside laboratory results will be
             acceptable].

          6. A CD4+ count >=350 cells/microliter (mcL) on 2 of 3 consecutive testing occasions (or
