CAMBRIDGE, Mass.--()--Sesen Bio, Inc. (Nasdaq: SESN), a late-stage clinical company developing targeted fusion protein therapeutics for the treatment of people with cancer, today announced the appointment of Dennis Kim, M.D., MPH, as chief medical officer. In this role, Dr. Kim will oversee the continued Phase 3 development of Vicinium, Sesen Bio’s lead targeted fusion protein, for patients with high-grade non-muscle invasive bladder cancer (NMIBC), as well as preparations for a marketing authorization submission and pre-commercial activities.

“We are thrilled to welcome Dennis to the Sesen Bio team and look forward to leveraging his deep drug development experience, particularly as we approach both six and 12-month data readouts from our VISTA Trial of Vicinium,” said Dr. Thomas Cannell, president and chief executive officer of Sesen Bio. “Dennis has an extensive track record of leading product candidates through development to approval and commercial launch. As the Vicinium program advances, his leadership will be instrumental in helping us bring this novel treatment to patients in need and achieving our mission of saving and renewing the lives of people with cancer.”

Dr. Kim brings significant drug development and commercialization experience to Sesen Bio’s leadership team. He has played key roles in both the approval and commercial launch of more than 10 products in oncology and immunology. Prior to joining Sesen Bio, Dr. Kim held senior and leadership roles at Ipsen, Spectrum, Novartis, Biogen Idec, and Amgen. Previously, Dr. Kim was an Epidemic Intelligence Service Officer at the Centers for Disease Control and Prevention where he played active roles in environmental and infectious disease studies. Dr. Kim earned his bachelor’s degree in chemistry and biology from Harvard, his M.D. from Stanford University and his MPH from the University of California, Los Angeles.

“I am highly encouraged by the data generated to date with Vicinium in high-grade non-muscle invasive bladder cancer, and believe this therapy has the potential to change the way we treat bladder cancer,” said Dr. Kim. “I am excited to work with the Sesen Bio team and board of directors to help propel Vicinium towards a potential approval so that we can help the many patients, and their families and physicians, who need a new and effective treatment option for this devastating cancer.”

In connection with the appointment of Dr. Kim, Sesen Bio entered into an employment agreement with Dr. Kim that, among other things, provides for the grant of a non-statutory stock option outside of Sesen Bio’s 2014 Stock Incentive Plan as an inducement material to Dr. Kim’s entering into employment with Sesen Bio in accordance with Nasdaq Stock Market Listing Rule 5635(c)(4).
