All
Summary
The purpose of this research study is to 1) evaluate the safety of a series of injections with the AGS-004 product in combination with a series of Vorinostat doses and 2) to help scientists evaluate ways of reactivating latent (non-acting) HIV virus and determine if the immune system can be made stronger to eliminate the activated HIV virus.

Criteria
Inclusion Criteria:

1. Confirmation of HIV-1 infection HIV infection is defined as documentation by any
licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test
kit at any time prior to study entry and confirmed by a licensed Western blot or a
second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by
HIV-1 antigen, plasma HIV-1 RNA viral load.

NOTE: The term "licensed" refers to a US FDA-approved kit.

WHO (World Health Organization) and CDC (Centers for Disease Control and Prevention)
guidelines mandate that confirmation of the initial test result must use a test that
is different from the one used for the initial assessment. A reactive initial rapid
test should be confirmed by either another type of rapid assay or an E/CIA that is
based on a different antigen preparation and/or different test principle (eg, indirect
versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.

2. Ages ≥ 18 to < 65 years old.

3. Karnofsky performance status >70.

4. Ability and willingness of participant to give written informed consent. Note: Due to
the lack of foreseeable benefit to study volunteers, illiterate or mentally
incompetent volunteers will not be enrolled.

5. Able and willing to provide adequate locator information.

6. On antiretroviral therapy (ART) for at least 24 months and on potent ART for > or
equal to 6 months prior to Screening (Visit 1).

Note: Potent ART is defined by current treatment guidelines and consists of at least 2
nucleoside/nucleotide reverse transcriptase inhibitors plus a non-nucleoside reverse
transcriptase inhibitor, integrase inhibitor, or a protease inhibitor without
interruption (defined as missing doses for more than two (2) consecutive days or more
than four (4) cumulative days) in the 24 weeks immediately prior to Screening (Visit
1). Other potent fully suppressive antiretroviral combinations will be considered on a
case-by-case basis. Prior changes in or elimination of medications for easier dosing
schedule, intolerance, toxicity, or other reasons are permitted if an alternative
suppressive regimen was maintained.

7. All participants must continue cART throughout the study.

8. Able and willing to adhere to protocol therapy and judged adherent to antiretroviral
therapy.

9. Plasma HIV-1 RNA < 50 copies/mL at screening (Visit 1).

10. Plasma HIV-1 RNA< 50 copies/mL at two time points in the previous 12 months prior to
study screening and never > or equal to 50 copies/mL on two consecutive time points in
the last 24 months prior to screening.

Note: A single unconfirmed plasma HIV RNA > or equal to 50 copies (c)/mL but < 1000
c/mL is allowed if a subsequent assay was < 50 c/mL but not in the 6 months preceding
the study screening visit (Visit 1).

11. CD4+ cell count ≥ 300 cells/mm3 at screening (Visit 1).

12. No history of auto-immune disease or auto-immune manifestations.

13. No active HCV infection (HCV antibody negative or no measureable HCV RNA) at or within
90 days of screening (Visit 1).

14. No active HBV infection (measureable HBV DNA or HBVsAg+) at or within 90 days of
screening (Visit 1).

15. Ability and willingness to communicate effectively with study personnel; considered
reliable, willing, and cooperative in terms of compliance with the protocol
requirements.

16. Adequate vascular access for leukapheresis.

17. Able to swallow pills without difficulty.

18. Able and willing to receive Intradermal (ID) injections without difficulty.

19. Women with written documentation of any of the following:

1. prior hysterectomy OR bilateral oophorectomy (removal of both ovaries)

2. bilateral tubal ligation or non-surgical permanent sterilization

3. Women with intact uterus and ovaries who have not had a period for ≥ one year AND
have a documented FSH level indicating postmenopausal status.

20. All male study volunteers must agree not to participate in a conception process (e.g.
active attempt to impregnate, sperm donation, in vitro fertilization) and, if
participating in sexual activity that could lead to pregnancy, the male study
volunteer and his female partner must use two reliable methods of contraception
(condoms, with or without a spermicidal agent; a diaphragm or cervical cap with
spermicide; an IUD; or hormonal-based contraception) simultaneously while receiving
the protocol-specified study products and for 6 weeks after stopping the study
products. Participants must use a reliable barrier method of contraception (condom,
cervical cap) along with another form of contraception.

For the female partners of male study volunteers who are receiving ritonavir,
estrogen-based contraceptives are not reliable and an alternative method should be
suggested.

21. Potential participant must have adequate organ function as indicated by the following
laboratory values:

System Laboratory Value Hematological Absolute neutrophil count (ANC) ≥1,500 /mcL Platelets
≥125,000 / mcL Hemoglobin ≥ 12 g/dL (males) and ≥ 11.5 g/dL (females) Coagulation
Prothrombin Time or INR ≤1.1 x upper limit of normal (ULN) Chemistry K+ levels Within
normal limits Mg++ levels ≥ 1.4 mEq/L Glucose Screening serum glucose ≤ Grade 1 (fasting or
non-fasting) Albumin ≥ 3.5 g/dL Renal Creatinine clearance determined eGFR > 60mL/min by
the CKD-Epi equation found at: https://www.qxmd.com/calculate/calculator_
