A Study of the Safety and Survival of the Adoptive Transfer of Genetically Marked Syngeneic Lymphocytes in HIV-Infected Identical Twins

Fecha de inicio: 1 de marzo de 1993

An identical twin pair, one of whom is seropositive for HIV, the other twin seronegative, by standard ELISA and Western blot testing. Patients with Kaposi's sarcoma are eligible for this study, but must not have received any systemic therapy for KS within 4 weeks prior to entry. The diagnosis of KS must have been confirmed by biopsy. Patients must be free from serious psychological or emotional illness and able to provide written informed consent. Anticipated survival greater than 3 months. 18 years of age or older. Treatment with FDA-approved and/or expanded access antiretroviral agent(s) for patients with baseline CD4 counts below 500 cells/mm3. Patients with baseline CD4 counts above 500 cells/mm3 are eligible to receive cell therapy on this protocol, but must be treated with antiretroviral therapy if evidence of significant and persistent viral activation occurs in association with a cell infusion (a 50 percent or greater increase above baseline in any virologic parameter for at least 2 consecutive weeks). No patients with lymphoma. Willing to comply with current NIH Clinical Center guidelines concerning appropriate notification of all current sexual partners of an individual regarding his or her HIV positive sero-status and the risk of transmission of HIV infection. No recent history of substance abuse unless evidence is provided of an ongoing therapeutic intervention (i.e., medical therapy or counseling) to control such abuse. No pregnancy.
