About
This phase I trial studies the side effects and best dose of rivogenlecleucel, and how well it works, in treating patients with blood cancer that has come back (recurrent) after stem cell transplant. Donor T-cell therapy (rivogenlecleucel) may help control transplant-related infections after stem cell transplant.
Full description
This is a dose-escalation study of rivogenlecleucel.
Each subject may receive up to 3 doses of rivogenlecleucel intravenously (IV), at intervals of no less than 28 days. Subjects meeting protocol-specified severity criteria for acute GVHD, chronic GVHD, cytokine release syndrome (CRS), prolonged aplasia, or encephalopathy will be treated with rimiducid infusion(s).
After completion of study treatment, patients are followed up every 6 months for 5 years and then annually for 10 years.

Inclusion criteria
Original HCT donor: The most recent transplant was from a related or unrelated donor with an allele-level match to the recipient at HLA-A, HLA-B, HLA-C, HLA-DRB1, HLA-DQB1 (10/10) or with a single antigen or allele mismatch (9/10), or with one or two umbilical cord blood units that are individually antigen-level matched to the recipient in at least 4 of 6 HLA loci (HLA-A, -B, -DRB1).
Graft source: The most recent transplant (and any previous allotransplant) was from mobilized peripheral blood stem cells and/or bone marrow and/or umbilical cord blood.
Transplant number: The relapse occurred after a 1st, 2nd or 3rd allogeneic HCT.
Diseases: The subject relapsed or progressed with the same or related disease which prompted the previous allogeneic HCT.
For subjects with persistent or relapsed acute B-cell lymphoblastic leukemia, the subject must have previously received a chimeric antigen receptor (CAR) T cell product and blinatumomab at any point (not necessarily to treat the current relapse or after the current allogeneic transplant), unless the subject is ineligible for a commercially-available CAR T cell product or blinatumomab or declines those treatments.
Relapse stage: The disease stage may be ascertained any time after engraftment of the original donor cells, where engraftment is defined as the first of 3 consecutive days of absolute neutrophil count >= 500/uL unsupported by granulocyte-colony stimulating factor (G-CSF) within the preceding 5 days. (Note that eligibility for the protocol does not require an ANC > 500/uL at the time of enrollment.) Subjects with any of the following disease stages are eligible for this protocol:
Subject may have received prior DLI and/or prior genetically-modified DLI such as CAR-T cells and/or prior chemotherapy other than purine analogues to treat minimal residual disease (MRD) or morphologic/clinical relapse or disease persistence but must have had relapse as defined at some point after the most recent HCT to be enrolled on this study.
Adequate HCT donor chimerism as indicated by original-donor T cell chimerism (from the most recent HCT) in peripheral blood >= 50%. In the case of double umbilical cord transplant, one of the cord donors should constitute >= 50% of the peripheral blood T cells.
For subjects who received genetically-modified T cells such as CAR-T cells or antigen-specific T-cell receptor (TCR) T cells, the non-engineered, polyclonal T cells must constitute at least 50% of total peripheral blood T cells.
Performance status: Karnofsky or Lansky performance status (PS) >= 80% or Eastern Cooperative Oncology Group (ECOG) PS 0-1.
Capable of giving informed consent, if the subject is 18 years of age or older. A parent or legal representative will be asked to consent for patients young than 18 years old.
DONOR: The donor must be available to undergo apheresis at the Seattle Cancer Care Alliance, South Lake Union site or at Bloodworks Northwest.
DONOR: The donor must be suitable for medical reasons to donate according to institutional Standard Practice Guidelines and National Marrow Donor Program (NMDP) guidelines, including the absence of transmissible infections (hepatitis A, B, HIV, HTLV I/II, syphilis, West Nile virus [WNV] and Chagas disease).
DONOR: The donor must not be homozygous to the recipient at an HLA allele that is common to recipient and donor. (Homozygosity at antigenic resolution is permitted.) Therefore, people who are homozygous at any HLA allele will be excluded.
DONOR: The donor may not knowingly be related to a subject on this study by blood (e.g., sibling, parent, child, cousin). This is to prevent "coercive recruitment" of donors.
DONOR: The donor must be 18-50 years old.
DONOR: Capable of giving informed consent.
DONOR: Not pregnant or breastfeeding at the time of apheresis.
DONOR: Not on any prescription medications other than birth control pills or vitamins.
DONOR: The donor must be cytomegalovirus (CMV) seronegative at the time of screening. For the product to be banked, the CMV polymerase chain reaction (PCR) done on the day of apheresis must be negative.
