ENMD-2076 is an oral drug that works by blocking certain enzymes called Aurora A and tyrosine kinase from working. These enzymes are needed for cells to divide including cancer cells. ENMD-2076 also works by stopping the growth of new blood vessels which would provide the tumor with nutrients for it to grow. It is believed that by blocking Aurora A and tyrosine kinase enzymes from working and stopping new blood vessels from growing, the tumors may stop growing or shrink.
