A Pilot Study of Immunization With HIV-1 Antigen Pulsed Allogenic Dendritic Cells in HIV-Infected Asymptomatic Patients With CD4+ T Cells > 350 Cells/mm3
Launched by NATIONAL INSTITUTE OF ALLERGY AND INFECTIOUS DISEASES (NIAID) · Aug 30, 2001
Current as of December 07, 2023
Dendritic cells are a type of white blood cell used by the body to fight infection. They are instrumental in presenting antigens (such as HIV antigens) to the body's immune system. Since dendritic cells are not functioning maximally in HIV-infected patients, infusion of dendritic cells from an HIV-negative sibling may enable the affected sibling's immune system to recognize foreign particles more readily and increase immune response against the virus. Dendritic cells from an HIV-negative sibling are obtained and treated with various viral proteins (HIV vaccines) or immunomodulators. The tr...
- Inclusion Criteria
- Patients must have:
- HLA A2+.
- Same cell type as donor sibling.
- CD4 count > 350 cells/mm3.
- HIV asymptomatic status.
- No HIV antivirals during study.
- Normal labs and chest x-ray.
- Donor siblings must have:
- HLA A2+.
- HIV negativity.
- Ability to donate cells on multiple occasions.
- Negative status for hepatitis B and C.
- Exclusion Criteria
- Concurrent Medication:
- Antiviral therapy (unless CD4 count declines to < 350 cells/mm3).
- Prior Medication:
- Antiviral therapy within 90 days prior to study entry.
The National Institute of Allergy and Infectious Diseases (NIAID, /ˈnaɪ.æd/) is one of the 27 institutes and centers that make up the National Institutes of Health (NIH), an agency of the United States Department of Health and Human Services (HHS).
