   - Karnofsky Performance score of 80 or higher

   - Stable HIV viral load between 5,000 and 200,000 copies/mL at the time of screening.
   Stable will be defined as a variation of less than 0.5 log10 in the 3 months prior to
   screening while on a stable regimen or no therapy

   - CD4 T cell count equal to or greater than 150 cells per μL at the time of screening

   - A body weight greater than 50 Kg

   - Adequate venous access and no other contraindications for leukapheresis

   - Subject must be willing to comply with study-mandated evaluations

Exclusion Criteria:

   - A history of any type of cancer or malignancy, with the exception of (successfully)
   treated basal cell or squamous cell carcinoma of the skin

   - A history or any features on physical examination indicative of cardiac disease or
   hemodynamic instability

   - Any history or any features on physical examination indicative of a bleeding diathesis

   - Previous treatment with any HIV experimental vaccine or any gene therapy products

   - A positive signal for VSV-G antibodies and/or VSV-G DNA in the blood at screening

   - Any of the following lab results:

      - Hemoglobin: <10 (males); <9.5 (females) g/dL

      - Absolute neutrophil count: < 1000/μL

      - Platelet count: <100,000/mm3

      - Serum creatinine: > 1.5 mg/dL (133µ mol/L)

      - AST or ALT: > 2.5 times the upper limit of normal

      - Total serum bilirubin: > 1.5 times the upper limit of normal

      - Proteinuria: 2+ on urine dipstick

   - Subjects must not be breastfeeding, be pregnant, or unwilling to use acceptable
   methods of birth control

   - Subjects must not be on chronic oral corticosteroids within 30 days of screening - (if
   subjects are prescribed a brief course of oral corticosteroids the use should be
   limited to less than 1 week), hydroxyurea, or immunomodulating agents (e.g., IL 2,
   interferon-gamma, granulocyte colony stimulating factors, etc.) within 30-days of
   screening or foreseeably need any of these within the study period

   - Subjects must not be using aspirin, dipyridamole, warfarin or any other medication
   likely to affect platelet function or other aspects of blood coagulation during the
   period when leukapheresis is scheduled

   - Subjects must not suffer from active drug or alcohol dependence or abuse, to an extent
   that, in the opinion of the investigator, would interfere with their ability to comply
   with study requirements

   - Any serious illnesses or acute opportunistic infection

   - Any other illness or condition which in the opinion of the investigator would exclude
   the subject from the study

   - Subjects unable or unwilling to give written informed consent
