Tourmaline Bio Appoints Dr. Clay Siegall as Chairman of the Board

NEW YORK, Dec. 14, 2023 (GLOBE NEWSWIRE) -- Tourmaline Bio, Inc. (“Tourmaline”) (NASDAQ: TRML), a late-stage clinical biotechnology company developing transformative medicines to dramatically improve the lives of patients with life-altering immune and inflammatory diseases, announced today that Clay Siegall, PhD, has been appointed as Chairman of the Board.

“We are absolutely thrilled that Clay has joined Tourmaline as Chairman of the Board,” said Sandeep Kulkarni, MD, Co-Founder and Chief Executive Officer of Tourmaline. “Clay built Seagen into one of the largest independent biotech companies in the world by taking a therapeutic concept and developing from it multiple successful medicines for cancer patients. He is a standout entrepreneur and a seasoned operating executive. Adding Clay’s demonstrated leadership to our team strengthens our ability to deliver transformative medicines for patients and positions Tourmaline well for many important milestones ahead.”

Dr. Siegall is currently President, Chief Executive Officer, and Chairman of the Board of Immunone, Inc., a biotechnology company focused on developing first-in-class and best-in-class targeted cancer therapies. He previously served as the CEO and President of Seagen, Inc., which he co-founded in July 1997. Under his 25 years of leadership, Seagen became the world leader in antibody-drug conjugate (ADC) therapeutics, earned FDA approvals for four cancer therapies, and grew to over $2 billion in annual revenue. During his tenure, he raised well over $1 billion in financing for Seagen from public and private market investors and oversaw the company’s successful acquisition of Cascadian Therapeutics. Pfizer, Inc. expects to close its purchase of Seagen for $43 billion in December 2023. Prior to Seagen, Dr. Siegall worked in positions of increasing responsibilities at Bristol Myers Squibb and at the National Cancer Institute. He received a PhD in Genetics from George Washington University and a BS in Zoology from the University of Maryland.

The company’s lead asset, TOUR006, has best-in-class potential to address the unmet needs of large numbers of patients across many indications. I look forward to working with Sandeep, the Board of Directors, and the rest of the management team to build a highly valuable organization.”
