A Phase I Study of ATRN-119, an ATR Inhibitor, in Combination With Decitabine in Patients With TP53-Mutated AML or Higher-Risk MDS
Washington University School of Medicine
Summary
This is a single-center, open-label, phase I study with dose escalation and dose expansion testing the combination of ATRN-119 and decitabine in patients with TP53-mutated acute myeloid leukemia (AML) or higher-risk myelodysplastic syndrome (HR-MDS). The dose escalation phase will enroll patients with previously untreated, relapsed, or refractory AML or HR-MDS, regardless of TP53 alteration status, with the primary objective of determining safety and tolerability of ATRN-119 plus decitabine. The dose expansion phase will only enroll patients with previously untreated AML or HR-MDS with a TP53 alteration, with the primary objective of identifying the recommended phase 2 dose (RP2D).
