“I am very honored and excited to join Arno Therapeutics as President and Chief Executive Officer,” said Mr. Mattes. “Arno currently has three innovative compounds in development that have the potential to be either first or best in class products upon regulatory approval. Arno is well-positioned to execute our comprehensive, global clinical development programs for all three assets as well as additional compounds that Arno may seek to strategically license. I have successfully built market-leading companies throughout my career and believe that my mission is to lead and accelerate the continued growth of Arno. Arno has the potential to become a significant presence in the oncology therapeutic space through the commercialization of novel oncology products that address unmet medical needs.”

I am confident that with Glenn’s leadership, those funds will be put to good use in building value for stockholders and developing much-needed treatments for patients suffering from cancer.”
