| NCT05748197 | A Study of ADCLEC.syn1 in People With Acute Myeloid Leukemia | PHASE1 | RECRUITING | 40 | — | — | Apr 18, 2024 | Apr 18, 2028 | Mar 10, 2026 | 7 | United States |
Dose escalation of ADCLEC.syn1 CAR T cells will follow Bayesian optimal interval (BOIN) design to inform dose-escalation decisions and potential maximum tolerated dose (MTD) estimation. Patients will be enrolled in cohorts of 3.

| ADCLEC.syn1 CAR T cells | EXPERIMENTAL | The dose escalation cohort size of 3 patients in each cohort will be infused with escalating doses of ADCLEC.syn1 CAR T cells to inform the RP2D. There are 4 planned flat-dose levels: 25 × 10\^6, 75 × 10\^6 , 225 × 10\^6 , and 450 × 10\^6 CAR T cells and 1 de-escalation dose: 10 × 10\^6 CAR T cells. After dose escalation, one or two dose levels will be selected for dose expansion cohort(s).Two to 7 days following completion of the conditioning chemotherapy, the frozen CAR T cells will be thawed and administered. Conditioning chemotherapy may occur either outpatient or inpatient, and T cell infusions will occur as inpatient. Up to approximately 12 additional patients each if two doses are selected or approximately 16 additional patients, if one dose is selected, will be treated in the dose expansion phase to determine RP2D. |
