About Terrestrial Bio, Inc.
Terrestrial is transforming the delivery of next-generation therapies, starting with GLP-1. Terrestrial's proprietary Tacterra™ microarray patch (MAP) and applicator platform consists of a patch resembling an adhesive bandage, which is applied with a preloaded applicator and removed after a few minutes. Once applied, each patch delivers bioactive tips into the skin, which dissolve quickly into the body, rapidly releasing their therapeutic payload. Designed for self-administration, the temperature-stable Tacterra™ platform enables precise, controlled delivery of a wide range of therapeutics without medical sharps or refrigeration.
Terrestrial has generated strong clinical and in-vivo proof of concept across multiple molecules. For more information, visit www.terrestrialbio.com .
