About ENMD-2076

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. ENMD-2076 has shown promising activity in Phase I clinical trials in solid tumor cancers, leukemia, and multiple myeloma. ENMD-2076 is currently in a Phase 2 trial for ovarian cancer, and preclinical and clinical activities are ongoing in assessing the compound’s applicability for other forms of cancer.
