A Study of the Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRCHIVMAB0115-00-AB (VRC01.23LS), Administered Intravenously or Subcutaneously to Healthy Adults
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
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 will be divided into 6 groups:
Some will get 1 dose of VRC01.23LS. They will visit the clinic up to 14 times in 24 weeks.
Some will get 3 doses, each 12 weeks apart. They will have 25 clinic visits over 48 weeks.
For some participants, the drug will be given through a tube attached to a needle inserted into a vein in the arm. This will take about 30 minutes. Others will receive the drug as an injection under the skin in a fatty area of the belly, arm, or thigh; each dose may need up to 3 individual injections.
Participants will stay in the clinic up to 8 hours on the days they receive VRC01.23LS.
Participants will receive a thermometer and measuring tool. They will check their temperature daily for 7 days after they receive the study drug. They will measure any redness, swelling, or bruising at the injection site.

Detailed Description
Study Design:
This first-in-human, open-label study will evaluate VRC01.23LS (VRCHIVMAB0115- 00-AB) in a dose-escalation design to examine safety, tolerability, dose, and pharmacokinetics (PK) in healthy adults. The primary hypothesis is that subcutaneous (SC) and intravenous (IV) administrations of VRC01.23LS will be safe and well-tolerated in healthy adults. A secondary hypothesis is that VRC01.23LS will be detectable in human sera with a definable half-life.
Study Products:
The VRC01.23LS broadly neutralizing monoclonal antibody (bnAb) targets the CD4 binding site in the HIV-1 envelope, is human in origin, and contains two amino acid modifications within the C-terminus of the heavy chain constant region designed to improve the antibody half-life in vivo. VRC01.23LS was developed by the VRC/NIAID/NIH and manufactured under cGMP regulations at the VRC Pilot Plant operated under contract by the Vaccine Clinical Materials Program (VCMP), Leidos Biomedical Research, Inc., Frederick. MD.
Subjects:
Healthy adults, 18-60 years of age
Study Plan:
This open-label study will include 6 groups to evaluate VRC01.23LS administered alone or by repeat dosing as shown below in the Study Schema. Enrollment will begin with the 5 mg/kg dose groups, and enrollment for subsequent dose groups will proceed after dose-escalation safety reviews. Assessment of safety will include solicited reactogenicity, clinical observation, and monitoring of hematological and chemical parameters at clinical visits throughout the study.
