Gossamer Bio Announces Appointment of Steven D. Nathan, M.D., and Skye Drynan to its Board of Directors

Gossamer Bio, Inc. (Nasdaq: GOSS), a clinical-stage biopharmaceutical company focused on the development and commercialization of seralutinib for the treatment of pulmonary arterial hypertension (PAH) and pulmonary hypertension associated with interstitial lung disease (PH-ILD), today announced the appointment of Steven D. Nathan, M.D., and Skye Drynan to its Board of Directors. Dr. Nathan is Medical Director of Inova’s Advanced Lung Disease Program and Lung Transplant Program and a Professor at the University of Virginia. Skye Drynan is the Founder, CEO and Creative Director of House of Skye, Ltd., and a former Partner and Senior BioPharma Analyst at Capital Group.

Dr. Nathan brings to the Board a wealth of medical expertise, particularly in PH-ILD, which occurs when pulmonary hypertension occurs in association with interstitial lung disease, a broad array of conditions manifesting as scarring of the lungs. With only one approved therapeutic option in the US, and none in the EU, PH-ILD represents an indication of high unmet need. With Dr. Nathan’s guidance, Gossamer is poised to expand its clinical program for seralutinib to include PH-ILD, underscoring Gossamer’s commitment to addressing rare forms of pulmonary hypertension, or PH.

Ms. Drynan joins the Board with an extensive background in finance, investment, and entrepreneurship, specializing in the biotechnology industry. Her more than 25 years of experience in investing and advising public biotechnology companies and technology companies, in addition to navigating the complexities of the financial markets, will be invaluable as Gossamer continues to advance the development of seralutinib and position itself as a leader in the treatment of PH.

“The addition of Dr. Nathan to our Board signifies a pivotal moment in Gossamer’s evolution,” said Faheem Hasnain, Co-Founder, Chairman and CEO of Gossamer Bio. “It not only demonstrates our dedication to the PH community, but it also solidifies our standing in the field, as we broaden our focus beyond PAH.

“Ms. Drynan’s expertise will strengthen our ability to capitalize on opportunities and navigate the financial landscape. Her proven track record as a biotech analyst and her entrepreneurial drive undoubtedly enhance our decision-making. Together these appointments elevate our strategic vision and position Gossamer for continued success."

Dr. Nathan is the Medical Director of Inova’s Advanced Lung Disease Program and Lung Transplant Program, a position he has held since 1996. He is also a Professor of Medical Education at the University of Virginia, a position he has held since 2020.
