Daphne Zohar, Founder and CEO of Seaport Therapeutics said, “We are grateful to have the partnership of this incredible group of new and existing investors who share our commitment of delivering better medicines for those suffering from depression, anxiety and other neuropsychiatric disorders, Seaport is advancing novel therapeutics that have proven clinical efficacy but had previously been held back by an issue we can now address with our Glyph platform. This financing enables the important clinical work that brings us another step closer to delivering new medicines to make a difference in the lives of patients and their families.”
Brett Zbar, M.D., Managing Director and Global Head of Life Sciences at General Atlantic said, “We are excited to partner with Daphne Zohar, Steve Paul and the team at Seaport, We are impressed with the team’s outstanding CNS clinical track record, as well as Seaport’s Glyph platform and innovative pipeline. The approach to clinical development and trial design demonstrates the deep neuropsychiatric expertise around the table, which we believe offers unique advantages that will contribute to Seaport’s success. We look forward to supporting the Company’s next phase of development.”
The programs in Seaport’s pipeline use the Glyph platform, which is designed to enable and enhance oral bioavailability, avoid first-pass metabolism and reduce liver enzyme elevations or hepatotoxicity and other side effects to advance clinically active drugs that were previously hindered by those limitations. The most advanced therapeutic candidate in the pipeline is SPT-300, an oral prodrug of allopregnanolone that is being advanced into a Phase 2b study for major depressive disorder with or without anxious distress that has the potential to be registration-enabling.
Steve Paul, M.D., Founder and Board Chair at Seaport Therapeutics said, “The development of important new neuropsychiatric medicines is often halted due to poor drug-like properties or unacceptable tolerability, challenges that our Glyph platform can now uniquely address, For instance, xanomeline was an effective drug that faced tolerability challenges, but once resolved, led to the FDA approval of Cobenfy™ (formerly KarXT) for schizophrenia. With Glyph, we believe each of Seaport’s programs could create similar life-changing value for patients.”
