The Company remains focused and committed to the completion of this study in order to bring patients a potentially superior delivery of lenalidomide that will enable them to live longer, better.

"Over the last several months, Starton has taken significant, critical steps forward in its clinical development," said Pedro Lichtinger, Chairman and CEO of Starton Therapeutics. "We will work diligently to ensure we continue to drive our clinical efforts to meet the completion of this landmark study.
