Phase I Study to Evaluate a Human Monoclonal Antibody (MAb) 10E8VLS Administered Alone or Concurrently With MAb VRC07-523LS Via Subcutaneous Injection in Healthy Adults
VRC 610: Phase I Safety and Pharmacokinetics Study to Evaluate a Human Monoclonal Antibody (MAB) VRC-HIVMAB095-00-AB (10E8VLS) Administered Alone or Concurrently With MAB VRC-HIVMAB075-00-AB (VRC07-523LS) Via Subcutaneous Injection in Healthy Adults
Background:
Human immunodeficiency virus (HIV) infection is a serious disease. There is no cure or vaccine to prevent infection. Using antibodies might be a good way to treat or prevent HIV. Antibodies are naturally made by the body to fight germs. Researchers want to test if two antibodies made artificially in a lab can help to prevent HIV infection. The antibodies are 10E8VLS and VRC07-523LS.
Objective:
To see if 10E8VLS and VRC07-523LS are safe and well-tolerated and how long they stay in the blood.
Eligibility:
Healthy adults ages 18-60
Design:
Volunteers were screened in another protocol.
Participants were enrolled in 1 of 4 groups:
Group 1 participants were enrolled to receive 1 dose of 10E8VLS.
Group 2 participants were enrolled to receive 3 doses of 10E8VLS.
Group 3 participants were enrolled to receive 1 dose of both 10E8VLS and VRC07-523LS.
Group 4 participants were enrolled to receive 3 doses of both 10E8VLS and VRC07-523LS.
Participants in Groups 1 and 3 were expected to be enrolled about 13 visits over 24 weeks.
Participants in Groups 2 and 4 were expected to be enrolled about 26 visits over 48 weeks.
Participants were weighed before each dose. Women may have had a pregnancy test. Participants had blood collected.
A small needle injected each dose into fatty tissue of the belly, upper arm, or thigh. Participants received between 1 and 8 injections per dose depending on their weight. Heavier participants received more injections.
Participants received a ruler and thermometer. They checked their temperature for 3 days after injection(s) and measured any redness, swelling, or bruising at the injection site.
At non-injection visits, participants had blood drawn and were checked for health changes or problems.

Detailed Description
VRC 610:
A Phase I Safety and Pharmacokinetics Study to Evaluate a Human Monoclonal Antibody (MAB) VRC-HIVMAB095-00-AB (10E8VLS) Administered Alone or Concurrently with MAB VRC-HIVMAB075-00-AB (VRC07-523LS) Via Subcutaneous Injection in Healthy Adults
Study Design:
This first-in-human, open-label study evaluated MAb 10E8VLS (VRC-HIVMAB095-00-AB) administered alone or concurrently (i.e., at the same visit) with MAb VRC07-523LS (VRC-HIVMAB075-00-AB) in healthy adults ages 18 to 60. The primary hypothesis was that administrations of 10E8VLS alone and concurrently with VRC07-523LS will be well-tolerated in healthy adults. A secondary hypothesis was that both broadly neutralizing monoclonal antibodies (bNAbs) will be detectable in human sera with a definable half-life.
Product Description:
The 10E8VLS and VRC07-523LS bNAbs target the HIV-1 envelope at distinct epitopes: 10E8VLS recognizes the membrane proximal external region (MPER) and proximal viral membrane lipid of gp41, while VRC07-523LS recognizes the CD4 binding site of gp120. Both antibodies are human in origin, contain two amino acid modifications within the C-terminus of the heavy chain constant region designed to improve antibody half-life in vivo, and were developed by the VRC/NIAID/NIH. The 10E8VLS and VRC07-523LS bNAbs were manufactured under current Good Manufacturing Practice (cGMP) regulations at the VRC Pilot Plant operated under contract by the Vaccine Clinical Materials Program (VCMP), Leidos Biomedical Research, Inc., Frederick, MD.
The 10E8VLS drug product was supplied at a concentration of 100 mg/mL in a sterile, aqueous, buffered solution of 5.25 mL in single-use 10 mL glass vials. The VRC07-523LS drug product was supplied at a concentration of 100 mg/mL in an isotonic, sterile solution of 6.25 mL in single-use 10 mL glass vials. Each drug product was prepared for administration in separate syringes.
Participants:
Healthy adults, 18-60 years of age.
Study Plan:
This open-label study included 4 dosing regimens of either 10E8VLS (5 mg/kg) administered alone or 10E8VLS (5 mg/kg) and VRC07-523LS (5 mg/kg). All injections were administered by the subcutaneous (SC) route. For Groups 1 and 2, 10E8VLS was to be administered once or three-times at 12-week intervals. For Groups 3 and 4, 10E8VLS and VRC07-523LS were to be administered once or three-times at 12-week intervals, respectively. Enrollment began with Groups 1 and 2, followed by Groups 3 and 4.
VRC 610 Study Schema:
- Group 1; Study Product: 10E8VLS; Planned Participants per Group: 3; Dose Administered SC: 5 mg/kg; Day 0
- Group 2; Study Product: 10E8VLS; Planned Participants per Group: 3; Dose Administered SC: 5 mg/kg; Day 0, Week 12*, Week 24*
- Group 3 (a,b); Study Product: 10E8VLS+VRC07-523LS; Planned Participants per Group: 5; Dose Administered SC: 5 mg/kg of each MAb; Day 0
- Group 4 (a,b); Study Product: 10E8VLS+VRC07-523LS; Planned Participants per Group: 5; Dose Administered SC: 5 mg/kg of each MAb; Day 0, Week 12*, Week 24*
- Total Planned Participants = 16
- Total Actual Participants = 9 (c)
(*)Participants received only one product administration on Day 0 because of the voluntary study pause and termination by Investigational New Drug (IND) Sponsor/Principal Investigator (PI) decision.
- Enrollment into Group 3 and 4 commenced after positive protocol safety review team (PSRT) review of safety data from Groups 1 and 2
- 10E8VLS and VRC07-523LS were provided in separate syringes and administered at the same visit.
- The expected enrollment was 16 participants; however, enrollment was voluntarily paused by the IND Sponsor/PI and the study ultimately stopped after several Grade 2 and Grade 3 redness local reactogenicity reactions were observed at 10E8VLS injection sites.
Study Duration:
Study participation was expected to be approximately 24 weeks for participants in Groups 1 and 3, and 48 weeks for participants in Groups 2 and 4. Participants in the repeat-dose groups (2 and 4) were converted to a modified schedule per protocol. Study participation for all participants was approximately 24 weeks after Day 0 product administration.
