Comparison of Dendritic Cell-Based Therapeutic Vaccine Strategies for HIV Functional Cure

Prior treatment

• Active drug or alcohol use or dependence that, in the opinion of the site investigator, would interfere with adherence to study requirements.
• Serious medical illness that requires systemic treatment and/or hospitalization within 30 days prior to entry.
• Use of systemic immunomodulators (eg, interleukins, interferons, cyclosporine), systemic cytotoxic chemotherapy, or investigational therapy within 60 days prior to study entry.
  • NOTE: Participants receiving stable physiologic doses of glucocorticoids, defined as the equivalent of prednisone ≤10 mg/day, will not be excluded. Stable physiologic glucocorticoid doses should not be discontinued for the duration of the study. In addition, participants receiving inhaled or topical corticosteroids, or topical imiquimod will not be excluded.
• Participation on any HIV immunotherapy or therapeutic vaccination trials within 6 months prior to study entry.
• History of positive HCV antibody with detectable HCV RNA in plasma within 48 weeks prior to study entry.
  • NOTE: Persons with positive HCV Ab but negative plasma HCV RNA are allowed to participate. Sites must document negative HCV RNA within 24 weeks of study entry.
• History of positive HBsAg within 48 weeks prior to study entry.
• Treatment for hepatitis C within 6 months prior to study entry.

Other illness

• Known allergy/sensitivity or any hypersensitivity to components of study vaccine or their formulation.
• Known chronic inflammatory conditions such as, but not limited to, rheumatoid arthritis, systemic lupus erythematosus, sarcoidosis, inflammatory bowel disease (i.e., Crohn's disease or ulcerative colitis), chronic pancreatitis, or autoimmune hepatitis, myositis, or myopathy.
• Initiation of ART during acute HIV-1 infection (as determined by the site investigator by history and/or available medical records).

Other

• Currently breastfeeding or pregnant
• Lack of adequate venous access that, in the opinion of the investigator, would interfere with study requirements.

• HIV-1 infection, documented by any FDA-approved assay. NOTE: The term 'licensed' refers to a US FDA approved kit, which is required for all investigational new drug (IND) studies.
• Receiving continuous ART for at least 24 months (defined as no interruptions longer than 14 consecutive days) and with no changes in the components of the ART for at least 8 weeks prior to study entry. A change in formulation (for example tenofovir disaproxil fumarate to tenofovir alafenamide) will not be considered a change in ART.
• Screening CD4+ cell count ≥350cells/mm3 obtained within 60 days prior to study entry by any US laboratory that has a CLIA certification or its equivalent.
• Plasma HIV-1 RNA levels \< 50 copies/ml for at least 24 months prior to study entry using a FDA-approved assay performed by any laboratory that has a CLIA certification or its equivalent. Participants must have at least one documented HIV-1 RNA less than 50 copies/ml \>24 months prior to study entry and at least one HIV-1 RNA less than 50 copies/ml within 12 months prior to study entry. All available HIV-1 RNA measurements must be \< 50 copies/ml during the 24 months prior to study entry except as allowed by the following note.
  • NOTE: Unconfirmed plasma HIV-1 RNA \> 50 copies/ml but \<200 copies/mL is allowed if followed by a subsequent value \< 50 copies/ml.
• Screening HIV-1 RNA levels \<50 copies/mL using a FDA-approved assay performed by any laboratory that has a CLIA certification or its equivalent within 60 days prior to entry.
• Men and women age 18 to 70 years, inclusive.
• The following laboratory values obtained within 60 days prior to entry:
  • Hemoglobin ≥10 g/dL Absolute neutrophil count (ANC) ≥1000/mm3 Platelet count ≥100,000/mm3 Creatinine ≤ 1.5x upper limit of normal (ULN) Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) (SGPT) ≤2.5x ULN
• Ability and willingness of participant to provide informed consent.
• In the opinion of the investigator, no medical, mental health or other condition that precludes participation.
• For females of reproductive potential, negative serum or urine pregnancy test within 48 hours prior to entry by any US clinic or laboratory that has a CLIA certification or its equivalent, or is using a point-of-care (POC)/ CLIA-waived test. Females of reproductive potential include women who have not been post-menopausal for at least 12 consecutive months, (i.e., who have had menses within the preceding 12 months) or women who have not undergone surgical sterilization (e.g. hysterectomy, bilateral oophorectomy, bilateral tubal ligation or salpingectomy). Self- report is acceptable documentation of menopause and sterilization.
• All participants must agree not to participate in the conception process (eg, active attempt to become pregnant or to impregnate, sperm donation, in vitro fertilization), and if participating in sexual activity that could lead to pregnancy, the participant/partner must use at least one reliable form of contraception (condoms, with or without a spermicidal agent; a diaphragm or cervical cap with spermicide; an IUD; or hormone-based contraceptive), while receiving study treatment and for 12 weeks following the final study vaccine.
