Phase I, open-label, dose-escalation and dose-expansion study evaluating the safety and efficacy of Universal Chimeric Antigen Receptor T-cell (UCART) targeting the Cluster of Differentiation 123 (CD123) in patients with relapsed/refractory acute myeloid leukemia (AML). The purpose of this study is to evaluate the safety and clinical activity of Universal Chimeric Antigen Receptor T-cells targeting CD123 (UCART123v1.2) and determine the Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose (RP2D).

    Dr. Rebecca Olin is a hematologist who specializes in bone marrow transplantation in adults. Her expertise encompasses treating acute leukemia, myelodysplastic and myeloproliferative disorders (conditions in which the bone marrow makes too many white blood cells) and aplastic anemia (a condition in which the body doesn’t make enough new blood cells).
