"The European Commission’s decision highlights the need for new AML treatment options and improves the commercial potential of OXi4503," stated William D. Schwieterman, M.D. President and Chief Executive Officer of OXiGENE. "We have recently put plans in place to accelerate the development of this promising agent by immediately advancing into the next phase of our ongoing phase 1b/2 clinical trial in the U.S., in which OXi4503 will be used in combination with the approved AML drug cytarabine instead of as a stand-alone investigational agent for the treatment of refractory AML."

Orphan designation in the European Union is granted to product candidates that are intended to treat life-threatening or chronically-debilitating conditions that affect no more than five patients per 10,000 of the EU population. Among other benefits, orphan designation provides for regulatory assistance and scientific advice from the European Medicines Agency during product development.
