Our Purpose

More than 15 million Americans live with autoimmune disease today, cycling through treatments that manage symptoms without ever reaching the source. ai3Bio was founded to change that.

Antibody Platform

A targeting antibody recruits the body's own immune cells to seek out and clear those same disease-causing T cells.
