ROCKVILLE, MD, Oct. 30, 2024 (GLOBE NEWSWIRE) --  MacroGenics, Inc. (NASDAQ: MGNX), a biopharmaceutical company focused on discovering, developing, manufacturing and commercializing innovative antibody-based therapeutics for the treatment of cancer, today announced that Scott Koenig, M.D., Ph.D., intends to step down as President and Chief Executive Officer early next year. The Company’s Board of Directors has retained Heidrick & Struggles to lead a search process to identify its next Chief Executive Officer and has established a special committee of the Board to oversee the transition process.

William Heiden, Chairman of the Board of Directors said, “Scott was a co-founder of MacroGenics twenty-four years ago and the Company has achieved many milestones under his leadership – including several partnered or company-owned FDA approved monoclonal antibody therapeutics developed by the company.  On behalf of the Board, I want to thank Scott for his incredible dedication to the Company’s mission of discovering and developing novel therapeutics to improve patient care.”

Mr. Heiden continued, “Today, MacroGenics has several innovative antibody-based therapeutics in development for the treatment of cancer, as well as significant alliances with leading pharmaceutical and biotechnology companies to develop and commercialize novel therapeutics.  The Company today has a broad portfolio of promising assets and a strong balance sheet, and the Board and Scott agreed that this is the right time to transition to our next phase of leadership. We look forward to continuing to benefit from his perspectives as an advisor and shareholder.”

“I am proud of our many achievements since our founding in 2000, in which we built a fully integrated, science-focused biotechnology company and have been successful in discovering, developing, manufacturing, and commercializing novel immunotherapeutics derived from our proprietary Fc-engineered antibody, bi-specific DART molecule, and antibody drug conjugate (ADC) technologies,” said Dr. Koenig. “Since the company’s IPO in 2013, we were able to fund a significant part of the development portfolio through the achievement of over $1 billion of non-dilutive capital via partnerships. Thanks to the incredible passion and dedication of the people at MacroGenics, three novel therapeutics from our pipeline advanced to approval, including MARGENZA® and ZYNYZ® to treat patients with cancer, and TZIELD® for individuals with early-stage Type 1 diabetes, and we have advanced a rich portfolio of clinical and preclinical molecules in development.  I am confident that MacroGenics is well positioned in its current mission to address the significant unmet medical needs of patients with cancer.   I look forward to continuing to support the Company in its work to achieve its key strategic objectives and create value for all our stakeholders.”
