About this study

Study CBX-250-001 is a Phase 1, open-label, dose-escalation study of CBX-250 in participants with relapsed/refractory AML, HR-MDS, CMML, and CML. Participants aged ≥ 12 years are planned to be enrolled. CBX-250 will initially be investigated on a fixed step-up dosing schedule. CBX-250 will be administered subcutaneously in 28-day cycles, with the first study drug dose administered on Cycle 1, Day 1. Cycle 1 will consist of a priming phase over 7 days, and a target phase over 28 days. Participants will continue CBX-250 until progressive disease (PD) or unacceptable toxicity. All subsequent treatment cycles will be 28 days.
