CAP256V2S

Background:
HIV is a serious disease with no cure or vaccine to prevent it. Using antibodies could be a way to prevent HIV infection. Antibodies are made by the human body to fight germs. Researchers want to test an antibody, CAP256V2LS.
Objective:
To test CAP256V2LS to see if it is safe and how the body responds to it.
Eligibility:
Healthy people, ages 18-60
Design:
Participants were screened with a medical history, physical exam, and blood tests. Some females had a pregnancy test.
Participants were assigned to one of two groups. Based on their group, they got 1 dose of CAP256V2LS in 1 of 2 ways:
Some participants got CAP256V2LS as an infusion. A thin tube was placed in an arm vein and CAP256V2LS was given into the vein using a pump.
Some participants got CAP256V2LS injected under the skin. A small needle was used to inject CAP256V2LS into the fatty tissue of the belly, arm, or thigh. They got 1 to 4 injections.
On the day they got CAP256V2LS, participants gave blood samples at different time points.
Participants were asked to check their temperature every day for 7 days after receiving CAP256V2LS. They used a tool to measure any redness, swelling, or bruising they may have at the site where they received the study drug.
Participants had visits at least 2-3 times during the first week after they got CAP256V2LS. Then they had about 9 more visits over the next 6 months. Visits included blood tests.
