Subjects with FLT3-mutated or IDH ½-mutated disease must have received at least one prior targeted therapy.
* Relapsed refractory myelodysplastic syndrome (MDS) with increased blasts who have received at least 1 prior line, but no more than 2 prior lines of anti-MDS therapy
* Other hematological malignancies who have received at least 1 prior line of standard of care for the respective disease
* Documentation of CD33 expression (or FLT3 expression if available) by individual institutional standard of care
