Study Overview
Brief Summary
This pilot clinical trial studies gene therapy following combination chemotherapy in treating patients with acquired immune deficiency syndrome (AIDS)-related non-Hodgkin lymphoma. Placing genes that have been shown in the laboratory to inhibit the growth and spread of the immunodeficiency virus (HIV) into the patient's peripheral blood stem cells may improve the body's ability to fight HIV. Drugs used in chemotherapy work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving gene therapy after combination chemotherapy may improve the body's ability to fight HIV and AIDS-related non-Hodgkin lymphoma.
Detailed Description
PRIMARY OBJECTIVE:
I. To demonstrate the safety and feasibility of rHIV7-shI-TAR-CCR5RZ-treated hematopoietic stem progenitor cells (HSPC) (lentivirus vector rHIV7-shI-TAR-CCR5RZ-transduced hematopoietic progenitor cells) transplantation in AIDS patients completing treatment for non-Hodgkin lymphoma (NHL).
SECONDARY OBJECTIVES:
I. To determine the effect of HIV infection on the presence of gene-marked blood cells as measured by woodchuck post-transcriptional regulatory element (WPRE) deoxyribonucleic acid (DNA) polymerase chain reaction (PCR) performed before, during, and after ATI.
II. To demonstrate the engraftment of gene-modified progeny cells following such treatment.
