Company Announces Chief Financial Officer Transition

CAMBRIDGE, Mass., June 12, 2019 (GLOBE NEWSWIRE) -- Mersana Therapeutics, Inc. (Nasdaq: MRSN), a clinical-stage biopharmaceutical company focused on discovering and developing a pipeline of antibody drug conjugates (ADCs) targeting cancers in areas of high unmet medical need, today announced the appointment of Brian C. DeSchuytner as Senior Vice President of Finance and Product Strategy. Mr. DeSchuytner is an accomplished life science professional with nearly two decades of experience spanning corporate strategy, finance, product development, and commercial launch. Mersana also announced today the resignation of David A. Spellman as Chief Financial Officer, who has decided to pursue other opportunities.

“We are very excited to welcome Brian to the team at Mersana; his breadth of experience in biopharmaceutical business strategy and his deep knowledge of oncology product development and commercialization will be valuable assets to Mersana as we advance our lead ADC therapeutic candidate through clinical trials in ovarian and lung cancer,” said Anna Protopapas, President and CEO of Mersana Therapeutics. “I’d also like to extend thanks to Dave Spellman for his valuable contributions to the Company, particularly in leading a successful transaction to finance the company into 2021, and wish him the best in his future endeavors.”

Mr. DeSchuytner joins Mersana from TESARO, where he was Vice President responsible for the ZEJULA® (niraparib) commercialization. Previously, he was Vice President responsible for the NINLARO® (ixazomib) global launch at Takeda Oncology. Earlier in his career, Mr. DeSchuytner held corporate development and strategy roles of increasing responsibility at Takeda Oncology and Novartis and was a leader in the life sciences practice of L.E.K. Consulting. He holds an M.B.A. from the Wharton School at the University of Pennsylvania, and a B.A. from Dartmouth College.  Mr. DeSchuytner will start at Mersana on July 10th.

“I am thrilled to join the team at Mersana at this important stage in the company’s growth,” said Mr. DeSchuytner. “The attractive combination of a first-in-class asset with demonstrated activity in heavily pre-treated disease, a differentiated platform, and an experienced management team is a tremendous opportunity to make a meaningful difference in the lives of people living with cancer. I look forward to leading the finance team and working alongside the other members of the Mersana management team to bring our medicines to patients.”
