About
The primary objective is to define the safety and tolerability of AB8939 in patients with AML by determining the dose-limiting toxicities, the maximum tolerated dose, and the recommended dose for dose expansion study.
Full description
This is a Phase 1/2, open-label, multi-center, non-randomized, 2-part study in patients with refractory and relapsed AML and refractory myelodysplastic syndrome.
Study AB18001 has a multi-stage design. The first part is a dose escalation study that aims to determine the safety, tolerability and pharmacokinetic profiles of consecutive daily intravenous administration of AB8939 in patients with refractory or relapsed AML or patients with refractory myelodysplastic syndrome, and to determine the recommended dose for the second-stage dose expansion study. This dose expansion study aims to determine the schedule for a Phase 2 trial in patients with relapsed/refractory AML and to also provide an early efficacy assessment of AB8939.
