About
Terrestrial Bio (formerly Vaxess Technologies) has developed a temperature-stable microarray patch (MAP) platform that delivers biologics through the skin without needles, refrigeration, or cold-chain logistics, with a wear time of just five minutes. Its lead program is a once-weekly semaglutide patch for obesity and metabolic disease, pursued via both prescription and Rx-to-OTC pathways. In preclinical studies the patch has shown bioavailability above 80% and pharmacokinetics comparable to subcutaneous injection. The company operates a clinical-grade manufacturing facility in Woburn, Massachusetts and is building a new R&D/manufacturing site in Boston.
