Gene Therapy in Treating Patients With Human Immunodeficiency Virus-Related Lymphoma Receiving Stem Cell Transplant

Registration Number
NCT02797470
Lead Sponsor
AIDS Malignancy Consortium
Brief Summary

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 introduce...

Primary Outcome Measures
NameTimeMethod
Percentage of Participants Who Achieve a Timely Engraftment1 month post-transplant

Timely engraftment is defined as a persistent an absolute neutrophil count (ANC) of at least 500 cells/mm3 and a platelet count of at least 20,000 cells/mm3 for at least 3 days

Secondary Outcome Measures
NameTimeMethod
Proportion of Study Participants Who Achieve Greater Than 5% Mononuclear Blood Cells Expressing Anti-HIV Genes in Peripheral Blood3 months post-transplant

To determine efficacy of the candidate product, defined as establishment of \> 5% mononuclear blood cells expressing anti-HIV genes

Proportion of Study Participants With Gene Modified HIV-1 Resistant Peripheral Blood Cells and Gut Mucosal Immune CellsUp to 24 months post-transplant

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

Quantity of Gene Modified HIV-1 Resistant Peripheral Blood Cells and Gut Mucosal Immune CellsUp to 24 months post-transplant

Summarized descriptively. Continuous measures will be summarized by mean (standard deviation \[SD\]) and median (range), with log transformation if necessary for skewed measures, as would be typical for cell counts.

Integration Sites of Vector Sequences in Circulating CellsUp to 24 months post-transplant

Single genome sequencing of HIV gp120 and HIV pol will be performed to understand sequence evolution following transplantation and detection of minority resistance variants.

Progression-free SurvivalTime from start of study treatment to relapse, progression, or death from any cause

Time-to-event data will be presented graphically by Kaplan-Meier plots and summarized by estimated median time to event (if that is estimable from the data) with 95% confidence interval.

Number of Days From the First Documentation of a Complete Response Until the First Day of RelapseTime from the first documentation of CR until first date that relapsed or progressive disease is objectively documented, assessed up to 15 years

Complete response is defined as the absence of any disease on imaging or by exam; progressive disease is defined as new lesions or new evidence of disease

Partial Response Rate and DurationUp to 15 years

Will be assessed following the Lugano Classification. In the absence of evident disease progression, response will be assessed formally at 3, 6, 12 and 24 months post transplant per study calendar.

CD4 Count RecoveryUp to 24 months post-treatment

At six months post-transplant, or later, ART will be voluntarily withheld for a 12 week period only for participants who have a CD4 count of 300 or higher with no detectable viral load. for participants in which the CD4 T-cell count has not risen to ≥ 300 cells/mm3 at the time of the planned ART interruption, ART will continue until the T-cell count has rise...

Persistence of Vector-transduced Cells Over TimeUp to 15 years

Vector stability analysis will be performed via qPRC sequencing.

Number of Participants With a Complete Response24 months

A complete response is the complete disappearance of any disease, as determined by imaging
