Busulfan and Gene Therapy After Frontline Chemotherapy in Treating Patients With AIDS-Related Non-Hodgkin Lymphoma
This pilot clinical trial studies busulfan and gene therapy after frontline chemotherapy in treating patients with acquired immune deficiency syndrome (AIDS)-related non-Hodgkin lymphoma (NHL). Drugs used in chemotherapy, such as busulfan, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Placing the gene for anti-human immunodeficiency virus (HIV) ribonucleic acid (RNA) into progenitor cells may make the body build an immune response to AIDS. Giving busulfan before gene therapy may help gene therapy work better.

I. To demonstrate the safety and feasibility of recombinant (r)HIV7-short hairpin RNA targeted to the HIV-1 tat/rev (shI)-trans-active response element (TAR)-chemokine cysteine-cysteine receptor 5 ribozyme (CCR5RZ)-treated hematopoietic stem progenitor cells (HSPC) (lentivirus vector rHIV7-shI-TAR-CCR5RZ-transduced hematopoietic progenitor cells) infusion in AIDS patients completing treatment for NHL and non-myeloablative conditioning with busulfan.
II. To demonstrate the engraftment of gene-modified progeny cells following such treatment.
III. To determine if selection of these gene-modified progeny cells occurs during analytical treatment interruption (ATI) of combination anti-retroviral therapy (cART).
I. To evaluate the pharmacokinetics of busulfan in patients with AIDS-related lymphoma (ARL).
II. To determine the effects of HIV-1 infection on the presence of gene-marked peripheral blood mononuclear cells (PBMC) as measured by woodchuck post-transcriptional regulatory element (WPRE) deoxyribonucleic acid (DNA) polymerase chain reaction (PCR) performed before, during, and after ATI.
Patients receive busulfan intravenously (IV) over 3 hours on day -2 followed by lentivirus vector rHIV7-shI-TAR-CCR5RZ-transduced hematopoietic progenitor cells IV on day 0.
After completion of study treatment, patients are followed up at 1, 2, 3, 6, 9, 12, 18, and 24 months and then annually for 13 years.
