We believe that we are well positioned for future success, with a promising and focused pipeline of assets as well as a strong commercial strategy,” concluded Mr. Paulson.

“It has been a pleasure working alongside the management team at Karyopharm as we grew the hypothesis about nuclear export and its role in cancer from an idea into a robust commercial enterprise with several programs in development that have significant potential for patients,” said Dr. Kauffman. “As the Company enters this next stage of its evolution and growth, I believe Karyopharm is well-positioned to deliver on its mission to bring differentiated medicines to patients battling cancer.”
