Avilar Therapeutics

Avilar Therapeutics is a Waltham, Massachusetts biopharmaceutical company pioneering the degradation of extracellular and membrane-bound proteins. Its ATAC (ASGPR Targeting Chimera) platform uses bifunctional small molecules that grab a disease-causing protein floating in circulation and shuttle it into the liver's endolysosome to be destroyed, extending the reach of targeted protein degradation beyond the inside of the cell. Launched in 2021 with backing from RA Capital, Avilar is applying the platform to autoimmune disease, preeclampsia, and other conditions driven by proteins that conventional drugs struggle to address.
