Brief Summary:
Clinical specimens are required from HIV positive individuals with viremia controlled by antiretroviral therapy to complete process development for a genetically modified autologous T cell product, AGT103-T. The product will be used in a subsequent early stage clinical trial in subjects with chronic HIV disease and viremia suppressed by antiretroviral therapy as the initial step in testing a functional cure for HIV disease. Enrolled participants provide a venous blood specimen (approximately 25mL) to determine their level of HIV-reactive CD4+ T cells. Subjects with positive T cell responses will be asked to undergo leukapheresis and their clinical specimens will be used to validate and qualify the AGT103-T cell product.

Condition or disease
HIV Infections

Detailed Description:

This protocol is to collect blood specimens from HIV positive individuals. The first blood draw will be done at the first study visit and if eligible, the second blood collection will be done via leukapheresis at the second visit. The leukapheresis procedures will follow the facility's standard operating procedures and protocol requirements for leukapheresis.

Volunteers will be males or females between and including the ages of 18 years and 60 years. Volunteers will provide written informed consent and meet all inclusion and exclusion criteria. Each participant can be in the study for up to 120 days (3 months).

The study will be conducted in accordance with GCP/ICH for human research for the purposes of obtaining clinical specimens for research. There is no endpoint for this study, however, data collected from this study will include, but not be limited to, gender, demographics, medical history, clinical laboratory values, and volume of the blood collected. The data will be summarized in future studies reporting results from a planned clinical trial.

Primary Outcome Measures :
  1. Collection of clinical specimens [ Time Frame: up to 120 days ]
    The blood samples collected will be tested to measure the absolute and relative levels of CD4+ and CD8+ T cells. Data will describe the range of CD4+ T cell and CD8+ T cell responses to peptide stimulation. The samples will also help validate the assays and processes for the development of the cell product to be used in a future clinical trial.
