MFI fold increase (FI) for AT1413 binding to CD45dim leukemic blasts isolated from newly diagnosed AML and patients with MDS. Depicted is MFI for AT1413 divided by the MFI of the negative control antibody (AT1002).

*Patient deferred further treatment and cytogenetic and molecular analyses were not performed.

†From this patient AT1413 was retrieved.
