- 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

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.

Key inclusion criteria (41 listed)
- Inclusion criteria associated with type and status of lymphoma, one of the following must be applicable:
- 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.
- 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.
Key exclusion criteria (22 listed)
- Participants who do not fulfill the criteria as listed above, are ineligible. Additionally, the presence of any of the following conditions will exclude a participant from study enrollment (timeline for all the exclusion criteria is within 8 weeks prior to enrollment in the screening segment):
- Participants with > 5% involvement of bone marrow by malignant cells (either by manual count or flow cytometry) prior to stem cell collection.
- Participants with any abnormal cytogenetics in the bone marrow not related to the lymphoma, and not deemed to be constitutional.
- Participants with unexplained anemia and/or thrombocytopenia.
- Participants with clear evidence of myeloproliferative disorders, or myelodysplastic disorders in the marrow.
Eligibility is decided by the study team after screening; this overview does not establish that a patient qualifies. Full inclusion and exclusion criteria.

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.
