Purpose

Adult participants (18-64 years old) with HIV-1 Infection on ART with a CD4 T cell count ≥ 350 cells/mm3 and viral suppression for ≥ 24 months will be enrolled on this study. Participants will receive two series of combination therapy consisting of one (1) intravenous (IV) dose of VRC-HIVMAB075-00-AB (VRC07-523LS) followed by 10 oral (PO) doses of Vorinostat (VOR) taken every 72 hours. Each series will last approximately 1 month and the two series will be separated by at least one month. Combination ART is (cART) maintained throughout the study. Participants will be on this study for approximately 36 weeks (or about 9 months).

The purpose of this study is to:

  • Evaluate the safety of two series of a VRC07-523LS infusion followed by multiple oral doses of VOR
mine if combining VRC07-523LS and VOR can have an impact on non-active HIV virus.

Detailed Description:

This is a phase I, single-site, open-label study to evaluate the effects of VOR given in combination with VRC07-523LS on persistent HIV-1 Infection in HIV-infected individuals suppressed on ART.
The investigators hypothesize that combination therapy with VRC07-523LS and VOR will be safe and well-tolerated by HIV-1-infected participants suppressed on ART.
In Step 1, all participants will undergo study screening and enrollment. Participants will complete a baseline Leukapheresis (#1) at Visit 2. Participants will be required to demonstrate the following in order to advance to Step 2:

  1. Baseline measurement of the frequency of resting CD4 T cell infection ≥ 0.3 infectious units per million (IUPM) determined by Quantitative Viral Outgrowth Assay (QVOA) (lower limit of detection is 0.03 IUPM), as a further decrease from this low frequency of infection cannot be definitively measured given the QVOA assay threshold, and
  2. Exhibit a measurable increase in resting CD4+ T cell-associated HIV RNA (ca-RNA)
following ex vivo exposure to VOR (Step 1).
These criteria assure that eligible enrolled participants will have a measurable endpoint, thus decreasing risk of study participation for participants who would not have a measurable outcome.
Participants progressing to Step 2 will receive two (2) doses of VOR 400 mg PO at a 72-hour interval, followed by leukapheresis (#2). If an increase in ca-RNA is observed in-vivo following the paired VOR dose, participants advance to Step 3.
In Steps 3 and 4, participants receive two series of a single VRC07-523LS infusion followed by multiple doses of VOR.
In the first series (Step 3), participants will receive one VRC07-523LS 40 mg/kg infusion (infusion #1) on Day 0 followed by the 1st dose of VOR 400 mg PO taken at home on Day 2. Participants will take VOR 400 mg PO every 72 hours for a total of 10 doses in Step 3.
In the second series (Step 4), participants will receive one VRC07-523LS 40 mg/kg infusion (infusion #2) on Day 60 followed by the 1st (of the 2nd series of VOR) dose of VOR 400 mg PO on Day 62. As in the previous Step, participants will take VOR 400 mg PO every 72 hours for a total of 10 doses.
Step 5 consists of 2 visits. The post-study treatment leukapheresis (#3) will be completed 5 - 8 weeks after the 2nd VRC07-523LS infusion. The End of Study Visit (EOS) will be scheduled to 2 - 4 weeks following the final leukapheresis (#3) visit.
