Company Description

Seaport Therapeutics is a clinical-stage therapeutics company focused on inventing and developing new medicines for patients with depression, anxiety, and other debilitating neuropsychiatric disorders.

Through our differentiated approach, we identify clinically validated mechanisms with established efficacy and safety profiles which had historically been limited by high first-pass metabolism, low bioavailability, and/or side effects.

We apply our proprietary GlyphTM platform to overcome those limitations and invent innovative oral therapies.

Glyph is a lymphatic-targeting prodrug technology which is designed to bypass first-pass metabolism and thereby enhance a drug’s oral bioavailability and reduce side effects.

This process, which we call “Glyphing,” also creates new composition of matter intellectual property.

We aim to develop novel, leading treatment options that will make a significant impact for patients and their families.
