We are a clinical-stage biotechnology company focused on the discovery and development of therapeutic proteins and antibodies that modulate the activity of G-protein coupled receptors (“GPCRs”). The discovery of biologics that can modulate GPCRs has historically been quite challenging. We have developed a proprietary technology platform called GEODe™ (GPCRs Engineered for Optimal Discovery) with the aim of addressing these challenges and enabling the discovery and development of GPCR-targeted biologic medicines that can modify the course of disease. We focus on areas of significant unmet medical need, often where therapeutic options are poor or nonexistent, and where new medicines have the potential to improve patients’ quality of life.

GPCRs are receptor molecules found on the surface of cells that act as sensors for various extracellular stimuli to enable communication between cells and their environment. These molecules regulate diverse aspects of human biology, including blood pressure, glucose metabolism, neuronal signaling, and immune surveillance. There are over 800 human genes encoding GPCRs, underscoring the extent to which human biology has relied on this molecular system for physiological control. The breadth of effects controlled by GPCRs is illustrated by the fact that greater than 30% of all approved drugs address targets in this class. The vast majority of these drugs, however, are small molecules, and their targets have been largely confined to a few GPCR subfamilies, many of which have a natural ligand that is also a small molecule.
