About Citryll

Citryll has translated a deep understanding of the neutrophil extracellular trap (NET) pathway to therapeutically address its central role in a broad range of immune-mediated inflammatory diseases. With a dual mode of action, the company’s lead antibody, CIT-013, has reached the clinic by demonstrating a precise and powerful ability to control NETs and NETosis. Citryll is initially developing CIT-013 as a novel drug for rheumatoid arthritis and hidradenitis suppurativa, building the foundation for a new treatment paradigm for autoimmune and autoinflammatory diseases.
