Study to Evaluate Effects of Vorinostat and HXTC on Persistent HIV-1 Infection in HIV-Infected Subjects Started on Antiretroviral Therapy (ART)
Condition: HIV-1 Infection
MeSH terms: Infections; Communicable Diseases; HIV Infections
Intervention: Vorinostat; HXTC
Intervention description: Participants meeting criteria for Step 1 (exhibit ex-vivo response to VOR) will progress to Step 2 where they will receive a single dose of VOR 400 mg followed by a leukapheresis. If an increase in cell-associated HIV RNA (ca-RNA) is observed in-vivo following the single VOR dose, they will be eligible to donate cells for the manufacture of HXTC (Step 3). Successful manufacturing of the HIV-1 antigen expanded specific T cells will progress participants to combination treatment in Steps 4 and 5. In Steps 4 and Step 5, participants will receive two series of VOR dosing and HXTC infusions, for a total 20 doses of VOR 400 mg and 5 HXTC infusions.; Participants meeting criteria for Step 1 (exhibit ex-vivo response to VOR) will progress to Step 2 where they will receive a single dose of VOR 400 mg followed by a leukapheresis.

Summary:

      This is a phase I, single-site, study to evaluate the effects of VOR and HIV-1 Antigen
      Expanded Specific T Cell Therapy (HXTC) on persistent HIV-1 Infection in HIV-infected
      individuals suppressed on ART. Twelve participants with durable viral suppression will be
      enrolled and will complete the study. All participants will receive the same treatment and if
      eligible, will be dosed with HXTC and VOR. Participants will continue their baseline ART
      regimen throughout the study.
    

Eligibility criteria:

        Inclusion Criteria:

          1. ≥ 18 years and < 65 years of age at screening

          2. Ability and willingness of participant to give written informed consent. NOTE: Due to
             the lack of foreseeable benefit to study volunteers, the study will not enroll
             illiterate or mentally incompetent volunteers.

          3. 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 (e.g.,
             indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.

          4. On antiretroviral therapy for at least 24 months and on potent antiretroviral therapy
             for greater than or equal to 6 months prior to Screening (Visit 1).

             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 more than 9 total days in the 12 weeks prior to
             Screening.

             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.

          5. Ability and willingness of participant to continue ART throughout the study.

          6. Able and willing to adhere to protocol therapy, schedule, and judged adherent to
             antiretroviral therapy (adherence defined in inclusion criterion 4.)

          7. Plasma HIV-1 RNA < 50 copies/mL at two time points in the previous 12 months prior to
             study screening (one time point can be at screening) and never > or equal to 50
             copies/mL on two consecutive time points in the last 24 months.

             NOTE: A single unconfirmed plasma HIV RNA > or equal to 50 copies/mL but < 1000 c/mL
             is allowed if a subsequent assay was < 50 copies/mL; but none in the 6 months
             preceding the study screening visit.

          8. Plasma HIV-1 RNA < 50 copies/mL at screening

          9. CD4+ cell count ≥ 350 cells/mm3 at screening

         10. No active HCV infection at or within 90 days of screening.

             Note: No active hepatitis C virus (HCV) defined as negative HCV antibody (HCVAb) or if
             HCVAb is positive, reflex HCV RNA is negative.

         11. No active hepatitis B virus (HBV) infection (measureable HBV DNA or HBV surface
             antigen-positive (HBVsAg+)) at or within 90 days of screening

         12. Women with written documentation of any of the following:

               1. prior hysterectomy OR bilateral oophorectomy (removal of both ovaries)

               3. Women with intact uterus and ovaries who have not had a period for ≥ one year AND
                  have a documented follicle stimulating hormone (FSH) level indicating
                  postmenopausal status.

         13. 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 intrauterine device (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.

             NOTE: For female partners who are receiving ritonavir, estrogen-based contraceptives
             are not reliable and an alternative method should be suggested.

         14. Ability and willingness to provide adequate locator information.

         15. Ability and willingness to communicate effectively with study personnel

         16. Adequate vascular access for HXTC infusion and leukapheresis.
