“We are grateful for Howard’s many contributions to ImmunoGen over the last eight years,” stated Stephen McCluski, ImmunoGen’s Chairman of the Board. “His counsel on a range of strategic issues has been instrumental as we’ve strengthened our leadership in ADCs and progressed our pipeline of novel candidates through clinical development. We value Howard’s collaboration and contributions to the Board and wish him continued success in his endeavors outside of ImmunoGen.”

“Stuart joins ImmunoGen’s Board at a pivotal moment in the Company’s evolution,” Mr. McCluski continued. “His international commercial expertise will be vital as we continue to advance mirvetuximab soravtansine in the FORWARD I registration trial, accelerate the development of our earlier-stage ADC assets, and evolve into a business with marketed products.”

As Vice President and General Manager of Amgen’s Oncology Business Unit, he was responsible for sales and marketing efforts for Aranesp^®, Neulasta^® and NEUPOGEN^®, and led the successful launches of XGEVA^® and Nplate^®. Prior to Amgen, Mr. Arbuckle held commercial roles of increasing responsibility at Celltech Pharmaceuticals and GlaxoSmithKline. He also previously served as a member of Cerulean Pharma’s Board of Directors. He is currently a national board member of the Cancer Support Community, a member of the Executive Committee and Health Section Governing Board for the Biotechnology Innovation Organization (BIO), and is co-chair of the BIO Standing Committee on Access and Value. Mr. Arbuckle has a degree in pharmacology and physiology from the University of Leeds in the United Kingdom.

Mr. Arbuckle stated, “ImmunoGen embarked on a journey last year to focus on its highest value programs and develop into a fully integrated biotech company.
