ENMD-2076 is a multi-kinase inhibitor, with activity against Aurora A kinase, FLT3, c-KIT, c-FMS and VEGFR-2 and -3. It appears to be tolerable, exhibits favorable pharmacokinetic profiles and has activity in patients with acute myeloid leukemia and multiple myeloma. Further evaluation with cytotoxic chemotherapy and targeted agents, which affect different pathways and have non-overlapping toxicities, in patients with hematological malignancies are warranted.
