FDA has approved omacetaxine mepesuccinate (Synribo, Teva) to treat adults with chronic myelogenous leukemia (CML), a blood and bone marrow disease. An estimated 5,430 people will be diagnosed with CML in 2012, according to the National Institutes of Health. Synribo is intended to be used in patients whose cancer progressed after treatment with at least 2 drugs from a class called tyrosine kinase inhibitors (TKIs), also used to treat CML.
