VRC 615: A Phase I, Open-Label, Dose-Escalation Study of the Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC-HIVMAB-0115-AB (VRC01.23LS), Administered Intravenously or Subcutaneously to Healthy Adults

Detailed Summary

Background: HIV causes AIDS, a serious disease that can lead to fatal infections. HIV infection can be controlled but not cured, nor is there a vaccine to prevent it. Antibodies may offer a promising new way to prevent HIV infection. Antibodies are proteins that are naturally made by the body to fight germs. One antibody (VRC01.23LS) has been tested in the lab and was found to block HIV-like viruses. Researchers want to find out if it is safe to inject VRC01.23LS into people. Objective: To test the safety of VRC01.23LS in healthy adults. Eligibility: Healthy people aged 18 to 60 years. Design: Participants were divided into 6 groups: Some got 1 dose of VRC01.23LS. They visited the clinic up to 14 times in 24 weeks. Some got 3 doses, each 12 weeks apart. They had 25 clinic visits over 48 weeks. For some participants, the drug was given through a tube attached to a needle inserted into a vein in the arm. This took about 30 to 90 minutes. Others received the drug as an injection under the skin in a fatty area of the belly, arm, or thigh; each dose may have needed up to 3 individual injections. Participants stayed in the clinic up to 8 hours on the days they received VRC01.23LS. Participants received a thermometer and measuring tool. They checked their temperature daily for 7 days after they received the study drug. They measured any redness, swelling, or bruising at the injection site.
