Participant Flow

BMT CTN 1902's enrollment was between January 2022 and December 2023 with 40 participants enrolled from 12 centers. The study opened to accrual in February 2021. Fifteen centers were activated for enrollment. The study closed to accrual on January 09, 2024.

There was a Safety Run-in that included the first three participants enrolled on the study with staggered enrollment to assess for excess early toxicity. These data were reviewed and enrollment was approved in the Continuing Enrollment Phase which began on October 14, 2022.

Patients complete apheresis and proceed to lymphodepleting chemotherapy with cyclophosphamide 300mg/m\^2 and fludarabine 30mg/m\^2 for 3 consecutive days followed by the infusion of BCMA CAR T-cells at a target dose of 450 x10\^6 cells. Maintenance lenalidomide, starting at 5mg a day for 21 days of a 28-day cycle will be initiated at a minimum of at least 30 days, but no later than 180 days after the CAR T-cell infusion and will continue until the patient reaches 12 months post CAR T-cell infusion and continue free of progression.

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 Year

Quantitation of CAR T-cells in peripheral blood will be determined at specified timepoints by quantitative PCR assay, measured in copies/mcg genomic DNA. Peak CAR T-cell expansion will be compared between subjects who are and are not in CR at 12 months, and between subjects who are and are not progression-free at 12 months.

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 Year

Quantitation of CAR T-cells in peripheral blood will be determined at specified timepoints by quantitative PCR assay, measured in copies/mcg genomic DNA. Persistence will be measured in 2 ways: 1) as an area under the curve (AUC) over first 6 months post CAR T-cell infusion; and 2) as still having detectable CAR T-cells at 6 months post CAR T-cell infusion. AUC6mos and 6- month persistence will be compared between subjects who are and are not in CR at 12 months, and between subjects who are and are not progression-free at 12 months.

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: 1 Year

BCMA expression at specified timepoints will be determined by immunohistochemical staining of bone marrow biopsy specimens and/or flow cytometric analysis of bone marrow aspirate material, in order to assess for baseline expression and potential loss of expression post-treatment. Both percent of MM cells that stain positive as well as staining intensity will be reported.

Outcome measures
