VRC 605: Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC-HIVMAB075-00-AB (VRC07-523LS), Administered Intravenously or Subcutaneously to Healthy Adults

HIV Prevention Clinical Trial

Official title: VRC 605: A Phase 1 Dose-Escalation Study of the Safety and Pharmacokinetics of a Human Monoclonal Antibody, VRC-HIVMAB075-00-AB (VRC07-523LS), Administered Intravenously or Subcutaneously to Healthy Adults

Status Completed

Clinical Trial Summary

Background:

Human immunodeficiency virus (HIV) is a global health threat. The body uses antibodies to fight infection. VRC07-523LS is an antibody directed against HIV. It may be used to prevent mother-to-child transmission of HIV. It may also prevent sexual transmission of HIV and treat HIV-1 infected people.

Objective:

To test the safety, tolerability, dose, and pharmacokinetics of VRC07-523LS in healthy adults.

Eligibility:

Healthy people ages 18-50

Design:

Participants will be screened with:

Medical history

Physical exam

Blood and urine tests

Participants will be assigned to 1 of 7 groups:

Groups 1-5 will get the drug at 1 visit and then be observed for 24 weeks.

Groups 6 and 7 will get the drug at 1 visit every 12 weeks, for a total of 3 doses over 48 weeks.

Participants will get the drug in 1 of 2 ways:

Infusion into a vein over at least 30 minutes. Participants will have blood tests 1, 3, and 6 hours after the infusion. They will have 1-3 visits during that week. Those in Group 7 will have 4-5 visits in the week after their second and third doses.

Injection into the fatty tissue under the skin. Participants will have blood tests before the injection. They will have 1-3 visits during that week. Those in Group 6 will have 4-5 visits after the second and third doses.

Visits include:

Physical exam

Blood and urine tests

Optional oral swabs to collect saliva

Participants will keep a diary of their temperature and symptoms for 3 days after each dose.

Clinical Trial Description

This is the first study of the VRC-HIVMAB075-00-AB (VRC07-523LS) monoclonal antibody (MAb) in healthy adults. It is a phase 1, dose-escalation study to examine safety, tolerability, dose, and pharmacokinetics of VRC07-523LS. The hypothesis is that VRC07-523LS will be safe for administration to healthy adults by the intravenous (IV) and subcutaneous (SC) routes.

Healthy adults 18-50 years of age will be enrolled. There are 4 open-label, dose escalations of VRC07-523LS from 1 mg/kg IV to 40 mg/kg IV, 1 route escalation from IV to SC, and 2 open-label groups to assess repeat dosing. Groups 1-5 are expected to include 3 subjects and Groups 6-7 are expected to enroll 5 subjects. Subjects will be followed for 24 weeks after the last study product administration. ;
