Clinical Trial Summary

This pilot clinical trial studies gene therapy after frontline chemotherapy in treating patients with acquired immune deficiency syndrome (AIDS)-related non-Hodgkin lymphoma (NHL). Placing genes for anti-human immunodeficiency virus (HIV) ribonucleic acid (RNA) into stem/progenitor cells may make the body build an immune response to AIDS. Giving the chemotherapy drug busulfan before gene therapy can help gene-modified cells engraft and work better.

Description:

PRIMARY OBJECTIVES: I. To evaluate 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). SECONDARY OBJECTIVES: 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. OUTLINE: 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, 7, 14, and 21 days and 1, 2, 3, 6, 9, 12, 18, and 24 months and then annually for 3 years.

• If the subject is female and of child-bearing potential, subject must have negative serum or urine pregnancy test within 7 days of treatment with research agent; men with partners of child-bearing potential and women of child-bearing potential must be willing to use medically effective birth control methods, e.g. contraceptive pill, condom, or diaphragm and continue this for one year post HSPC infusion
• Subjects must be on a prophylactic regimen for Pneumocystis carinii pneumonia, or agree to begin such treatment, if the cluster of differentiation (CD)4 counts are < 200 cells/uL

SECONDARY ELIGIBILITY CRITERIA FOR GENE-MODIFIED HSPC INFUSION:

• Subjects must complete the filgrastim (G-CSF)/plerixafor mobilization of peripheral blood progenitor cells and must have collected at least 7.5 x 10^6 CD34+ cells/kg, sufficient for preparation of both, a back-up of 2.5 x 10^6 CD34+ cells and the research product
• Research product must pass all release tests
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control or abstinence) prior to study entry and for six months following duration of study participation; should a woman become pregnant or suspect that she is pregnant while participating on the trial, she should inform her treating physician immediately
• All subjects must have the ability to understand and the willingness to sign a written informed consent

Exclusion Criteria:

• Any AIDS-related opportunistic infection occurring within the past year and for which treatment has been unsuccessful would be considered exclusionary, but this is done on a case-by-case basis as determined by the principal investigator
• Active cytomegalovirus (CMV) retinitis or other active CMV-related organ dysfunction; patients with a history of treated CMV infection are not excluded
• Patients who are hepatitis C virus (HCV) antibody positive and HCV ribonucleic acid (RNA) or hepatitis B virus (HBV) surface antigen positive and HBV DNA positive
• Pregnant or nursing women
• Active central nervous system (CNS) lymphoma, history of HIV-associated encephalopathy; dementia of any kind; seizures in the past 12 months; patients with a history of positive cerebrospinal fluid cytology that has become negative with intrathecal chemotherapy and the patient has been in remission for at least 12 months are eligible
• Any history of HIV-1 associated encephalopathy; dementia of any kind; seizures in the past 12 months; any perceived inability to directly provide informed consent (note: consent may not be obtained by means of a legal guardian)
• Any medical or physical contraindication or any other inability to undergo HSPC collection
• Patients should not have any uncontrolled illness including ongoing or active infection
• Patients may not be receiving any other investigational agents, or concurrent biological, chemotherapy, or radiation therapy
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to G-CSF/filgrastim (Escherichia [E] coli producing cell line), plerixafor or busulfan
• Patients with other active malignancies other than skin cancers are ineligible for this study
• Subjects, who in the opinion of the investigator, may not be able to comply with the safety monitoring requirements of the study will be considered non-compliant
