Seaport presents phase 1 data for anxiety disorder drug candidate
PureTech Health's Seaport Therapeutics presented Phase 1 data for GlyphAgo, an anxiety disorder drug candidate, at a congress in Munich. The trial showed a 6.8-fold increase in bioavailability of agomelatine compared to unmodified agomelatine and lower pharmacokinetic variability. Seaport plans to initiate a Phase 2/3 trial in early 2027 and expects topline results from a Phase 2a trial in early 2028.
