“Tucker brings outstanding operational experience having successfully helped lead an organization through the transition to becoming a commercial company,” said Ian Mortimer, President and Chief Executive Officer of Xenon. “Together with our senior executive team, Tucker will be instrumental in our strategic approach to building out the necessary functions, strategies, systems, and infrastructure critical to our future commercial success, as we await topline data from X-TOLE2, our ongoing Phase 3 study of azetukalner in epilepsy, and prepare for our first anticipated drug approval.”

“I am thrilled to join Xenon at such a critical juncture as the Company prepares to report topline results for the X-TOLE2 study and plans for the anticipated launch of azetukalner in epilepsy and beyond,” said Mr. Kelly. “It is rewarding to be part of a team that has the potential to deliver life-changing therapeutics to patients, and I look forward to applying my experience positioning companies for successful commercialization and long-term growth.”

Most recently, he served as Executive Vice President, CFO and Treasurer at Deciphera Pharmaceuticals, Inc., now a wholly owned subsidiary of Ono Pharmaceuticals, Co., Ltd. As a senior executive at Deciphera, Mr. Kelly oversaw the growth of the company as it advanced from discovery to direct commercialization in the U.S. and abroad. In this role, he built and strengthened the company’s investor base and led strategic financial planning related to Deciphera’s corporate strategy and pipeline, culminating in its $2.4B acquisition by Ono in 2024. Before joining Deciphera, Mr. Kelly also served as CFO of various public and private life sciences companies including AdvanDx, Inc., deCODE genetics, Inc., and Critical Therapeutics, Inc. Prior to those roles, Mr. Kelly was a life sciences investment banker at Robertson Stephens and Canaccord Adams, and earlier in his career he was an attorney in the corporate and securities group of Foley Hoag LLP.
