  • Biopsy-proven Burkitt's lymphoma, meeting one of the following criteria (timeline 8 months prior to enrollment):
  • In second complete remission after relapse following initial complete remission,
  • Failed induction therapy, but responds (very good partial remission, complete remission, or near complete remission) to salvage therapy (i.e., chemosensitive disease).
  • Biopsy proven plasmablastic lymphomas, or peripheral T cell lymphoma (with the exception of ALK+ type in first or second complete remission) *NOTE: Patients meeting the following criteria are exempt from the 8-month timeline and do not require additional biopsy:
  • Patients who have never achieved a complete remission on the last biopsy-proven site of disease and went on to the next therapy then achieved a complete remission.
  • Patients who relapsed quickly (within 3 months of their last chemotherapy) and now have achieved a complete remission with salvage therapy.
  • HIV-1 infection, as documented by any federally approved, licensed HIV rapid test performed in conjunction with screening (or ELISA, test kit, and confirmed by Western blot or other approved test). Alternatively, this documentation may include a record demonstrating that another physician has documented the participant's HIV status based on either: 1) approved diagnostic tests, or 2) the referring physician's written record that HIV infection was documented, with supporting information on the participant's relevant medical history and/or current management of HIV infection.
  • Must be on a multi-drug anti-HIV regimen (excluding zidovudine [AZT, ZDV, Retrovir®, or agents containing zidovudine (e.g., Combivir® and Trizivir®)], and efavirenz [Sustiva®, or agents containing efavirenz (e.g., Atripla®)]).
  • Participants on zidovudine [AZT, ZDV, Retrovir®; including Combivir® and Trizivir®] and efavirenz [Sustiva®; including Atripla®] must switch to an alternative regimen without anticipated drug-drug interactions or myelosuppressive properties based on known viral resistance patterns and/or ART history, such as raltegravir and Truvada (emtricitabine and tenofovir) at least two weeks prior to the transplant.
  • o Participant taking ARTs must satisfy one of the following:
  • Undetectable HIV viral load (< 50 copies/mL). For patients who have had negative viral loads in the past 6 months and no known HIV viral load >500 copies/mL within the last 6 months, minor fluctuations of viral load (isolated escalations up to 500 copies/mL) are acceptable. The participant's history of negative viral loads may be documented with recent laboratory results and/or a record from the participant's HIV care provider.
  • If viral load is detectable at < 2000 copies/mL a review of previous antiretroviral regimens or previous genotypic or phenotypic testing which indicate the ability to fully suppress virus by addition of sensitive drugs must be performed. This review will be carried out by the protocol ID team or the ID specialist caring for the patient.
  • If viral load is detectable at ≥ 2000 copies/mL, a current HIV genotype and/or phenotype must be obtained. If a HAART regimen to which the patient's virus is sensitive can be determined based on genotype and previous antiretroviral experience, then the patient will be considered eligible in this regard. This review will be carried out by the protocol ID team or the ID specialist caring for the patient.
  • General Inclusion Criteria (timeline: within 8 weeks prior to enrollment in the screening segment, unless otherwise specified)
  • Karnofsky performance status of 70-100%. ECOG performance status <2
  • SGOT and SGPT ≤ 2.5 times upper limit of normal (ULN). Serum bilirubin ≤ 2.5 times ULN except for participants who are on atazanavir or indinavir, or with elevated indirect bilirubin related to bilirubin conjugation issues such as Gilbert's disease, provided that the participant's direct bilirubin is within normal institutional limits.
  • Participants who are hepatitis C virus antibody positive, or hepatitis B virus surface antigen positive must be free of clinical evidence of cirrhosis as determined by the principal investigator in consultation with the institutional Gastroenterology Service.
  • Participants with Hepatitis B should be on appropriate anti-viral therapy at the time of the transplant, and their viral load should be negative.
  • Serum creatinine ≤ 2 times ULN.
  • Creatinine clearance ≥ 60 mL/min by the modified Cockcroft-Gault Formula.
  • PT/PTT ≤ 2 times upper limit of normal (ULN), or international normalized ratio (INR)/PTT ≤ 2 times the ULN.
  • FEV-1 or DLCO (corrected for hemoglobin) ≥ 50% predicted.
  • LVEF ≥ 50% by 2D ECHO or MUGA scan.
  • Not pregnant or nursing, with negative serum pregnancy test. Pregnant women are excluded from this study because the conditioning regimen has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with BEAM, breastfeeding should be discontinued. These potential risks may also apply to other agents used in this study.
  • Participants should agree to practice effective contraceptive precautions and to use at least one method of contraception for the duration of the study and for 3 months post-transplant.
  • Age ≥18 years. Because only adult transplant centers are participating as study sites.
  • Life expectancy of greater than 3 months.
  • Ability to understand and the willingness to sign a written informed consent document.
  • Receipt of a stable ART regimen for at least 3 weeks prior to enrollment.

About this study

Official title: A Phase I Study of Stem Cell Gene Therapy for HIV Mediated by Lentivector Transduced, Pre-Selected CD34+ Cells

This phase I/II trial studies the side effects and best dose of gene therapy in treating patients with human immunodeficiency virus (HIV)-related lymphoma that did not respond to therapy or came back after an original response receiving stem cell transplant. In gene therapy, small stretches of deoxyribonucleic acid (DNA) called "anti-HIV genes" are introduced into the stem cells in the laboratory to make the gene therapy product used in this study. The type of anti-HIV genes and therapy in this study may make the patient's immune cells more resistant to HIV-1 and prevent new immune cells from getting infected with HIV-1.

Read the detailed description

PRIMARY OBJECTIVE:

  1. Safety, defined as timely engraftment (the collective establishment of a persistent absolute neutrophil count of at least 500 cells/mm^3 and platelet count of 20,000 cells/mm^3 without transfusion for 3 consecutive measurements of laboratory values obtained on different days) by one month post-transplant, in the absence of any grade 3 and 4 non-hematopoietic organ toxicity that can be attributed (possibly, probably, or definitely) to lentiviral transduced stem cell transplant, excluding alopecia, or any clonal expansion and excluding expected toxicities that are associated with the pre-transplant conditioning regimen.

SECONDARY OBJECTIVES:

  1. To determine efficacy of the candidate product, defined as establishment of > 5% mononuclear blood cells expressing anti-HIV genes in the peripheral blood at 3 months post-transplant.

II. To determine the presence, quantity, and duration of gene modified HIV-1 resistant peripheral blood cells and gut mucosal immune cells.

III. To study the integration sites of vector sequences in circulating cells. IV. To study progression-free survival. V. To study overall survival. VI. To study complete response rate and duration. VII. To study partial response rate and duration. VIII. To study time to neutrophil engraftment (first measurement of 3 consecutive laboratory values on different days) of absolute neutrophil count [ANC] >= 500 cells/mm^3).

IX. To study time to platelet engraftment (first measurement of 3 consecutive measurements laboratory values obtained on different days) of platelets >= 20,000 cells/mm^3 without platelet transfusions 7 days prior).

  1. To study hematologic function at day 100 (ANC > 1500, hemoglobin [Hb] > 10 g/dl without transfusion and platelets > 100,000) XI. To study CD4 recovery at the conclusion of the trial. XII. To study safety in terms of toxicities, infections, transfusions, and infusion-related reactions.

XIII. To study HIV-1 viral load over time. XIV. To study persistence of vector-transduced cells over time.

EXPLORATORY OBJECTIVE:

  1. To evaluate the presence and the magnitude of expansion of HIV-1 resistant immune cells in the peripheral blood and gut mucosa of transplanted participants, subsequent to withholding anti-retroviral therapy (ART).

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Autologous Hematopoietic Stem Cell Transplantation, Carmustine and Cytarabine in people with HIV Infection and Mature T-Cell and NK-Cell Non-Hodgkin Lymphoma, run by AIDS Malignancy Consortium at 4 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 41 inclusion and 22 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 18 May 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 20 Jul 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants Who Achieve a Timely Engraftment (time frame: 1 month post-transplant). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 May 2026.
