"Seaport's scientific approach to advancing neuropsychiatric medicines is exciting and differentiated, and I look forward to supporting the Company's commitment to maintaining the highest standards of financial oversight and governance as it continues its mission to make a difference in the lives of patients and their families impacted by these conditions."
