The poster is entitled, ‘Combining oral Wnt/β catenin/inflammasome pathway inhibitor, a bis-benzylisoquinoline alkaloid (ES-3000) with oral decitabine/cedazuridine (ASTX727)* as a treatment strategy for myelodysplasia’. The primary objectives of the initial phase of the trial are to assess the safety profile of ES-3000 and determine the recommended phase 2 dose and dosing schedule of ES-3000 in combination with fixed-dose decitabine/cedazuridine (ASTX727). The results indicate a response in 40% of evaluable patients who received ES-3000 as a single agent. The dose-limiting toxicities as per BION modeling allowed the study to dose escalate.
