ImmunoGen Appoints Isabel Kalofonos as Senior Vice President and Chief Commercial Officer

WALTHAM, Mass.--()--ImmunoGen, Inc. (Nasdaq: IMGN), a leader in the expanding field of antibody-drug conjugates (ADCs) for the treatment of cancer, today announced that Isabel Kalofonos has been appointed Senior Vice President and Chief Commercial Officer.

"We are excited to welcome Isabel to ImmunoGen's Executive Committee to lead our best-in-class commercial organization at this important moment for the company. Since the approval of ELAHERE® (mirvetuximab soravtansine-gynx) in late November for platinum-resistant ovarian cancer, we have made significant progress with the launch, highlighted by the breadth and depth of adoption, strong demand for FRα testing, and favorable market access coverage," said Mark Enyedy, ImmunoGen's President and Chief Executive Officer. "Isabel's deep experience in global pipeline commercialization and product launches will enhance the strength of our launch execution and complement our existing capabilities as we seek to establish ELAHERE as the standard of care for FRα-positive platinum-resistant ovarian cancer, investigate its potential in platinum-sensitive disease, and advance our portfolio of earlier-stage ADCs.”

Ms. Kalofonos joins ImmunoGen from Galderma, where she served as Senior Vice President and Global Head of the Prescription Business Unit. During her tenure, she led the launch preparation for nemolizumab, a monoclonal antibody for the treatment of atopic dermatitis and prurigo nodularis, as well as global market access, real-world evidence, pricing, and health economics and outcomes research. She also led all commercial franchises of prescription products. Prior to Galderma, Ms. Kalofonos held roles of increasing responsibility at Takeda Pharmaceuticals (formerly Shire), most recently serving as Vice President and Head of the Hereditary Angioedema (HAE) franchise - a 2.5 billion dollar business. In this role she oversaw the global blockbuster launch of TAKHZYRO® (lanadelumab-flyo). Prior to the Takeda acquisition, Ms. Kalofonos held roles of increasing responsibility at Shire within corporate strategy, new product planning, and commercial, and gained experience across multiple therapeutic areas including immunology, rare diseases, oncology, neurology, transplant, and gene therapy. Before Shire, she worked in commercial, business strategy, and product launch positions at Forest Labs, Bionevia Pharmaceuticals, and Sunovion Pharmaceuticals. Ms. Kalofonos received a BS from Pontificia Universidad Javeriana and an MBA from Babson College.

"I am delighted to join ImmunoGen during this exciting time in its evolution into a commercial organization," said Ms. Kalofonos. "I am encouraged by the strong initial uptake and positive reception from physicians around the launch of ELAHERE as the first and only ADC approved for ovarian cancer, and I look forward to supporting its continued rollout, expanding its commercial presence to the EU and helping to bring ImmunoGen's other novel ADCs for solid tumors and hematologic malignancies to patients."
