A Phase 1 Trial to Evaluate CAP256V2LS in Healthy Adults

Summary

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.
