Description: ENMD-2076 is an orally-active, Aurora A/angiogenic kinase inhibitor with a unique kinase selectivity profile and multiple mechanisms of action. ENMD-2076 has been shown to inhibit a distinct profile of angiogenic tyrosine kinase targets in addition to the Aurora A kinase. Aurora kinases are key regulators of mitosis (cell division), and are often over-expressed in human cancers. ENMD-2076 also targets the VEGFR, Flt-3 and FGFR3 kinases which have been shown to play important roles in the pathology of several cancers.

Additional Information

ENMD-2076 is a novel orally-active, Aurora A/angiogenic kinase inhibitor with potent activity against Aurora A and multiple tyrosine kinases linked to cancer and inflammatory diseases. ENMD-2076 is relatively selective for the Aurora A isoform in comparison to Aurora B. Aurora kinases are key regulators of the process of mitosis, or cell division, and are often over-expressed in human cancers. ENMD-2076 exerts its effects through multiple mechanisms of action, including antiproliferative activity and the inhibition of angiogenesis. ENMD-2076 has demonstrated significant, dose-dependent preclinical activity as a single agent, including tumor regression, in multiple xenograft models (e.g. breast, colon, leukemia), as well as activity towards ex vivo-treated human leukemia patient cells. ENMD-2076 has completed a Phase 1 study in patients with solid tumors and is currently in a multi-center Phase 2 study in ovarian cancer as well as Phase 1 studies in multiple myeloma and leukemia. ENMD-2076 has received orphan drug designation from the United States Food and Drug Administration (the “FDA”) for the treatment of ovarian cancer, multiple myeloma and acute myeloid leukemia (“AML”). In the United States, the Orphan Drug Act is intended to encourage companies to develop therapies for the treatment of diseases that affect fewer than 200,000 people in this country. Orphan drug designation provides us with seven years of market exclusivity that begins once ENMD-2076 receives FDA marketing approval. It also provides certain financial incentives that can help support the development of ENMD-2076. See EntreMed's web.
