VRC-01-LS

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.

This study will evaluate the safety, pharmacokinetics, and antiviral activity of VRC-HIVMAB060-00-AB (VRC01) and VRC-HIVMAB080-00-AB (VRC01LS) in the serum and mucosa of healthy, HIV-uninfected adults.
