Targeting the pathobiology of neutrophil extracellular traps
Citryll – a dutch biotech company – is taking a new approach to treat autoimmune and other human diseases like lupus, vasculitis, pulmonary fibrosis, asthma, rheumatoid arthritis and organ damage due to sepsis, by targeting and inhibiting the source of auto-antigens and neutrophil extracellular trap (NET) derived toxic molecules instead of broadly targeting inflammation or acquired immunity.
Scientific Approach
Citryll targets Neutrophil Extracellular Traps (NET) formation with a human antibody CIT-013 that interferes with the formation of NETs as well as promotes the clearance of NETs. A range of human diseases with potential for SLE, RA, vasculitis, asthma, IPF and other indications can be treated with CIT-013.
CIT-013 Development
A first human dosing will be done in 2021 as part of a Single Ascending Dose (SAD) study in healthy volunteers. GMP production and formulation of the antibody is being carried out by Citryll’s CMC partner Lonza and CTA enabling studies are being finalised in 2020.

Neutrophil extracellular traps (NETs), are part of the innate immune defense mechanisms but become pathogenic when their release is abundant and uncontrolled. Citryll’s lead tACPA (therapeutic anti-citrullinated protein antibody) CIT-013 program interferes with NET formation, function, and clearance downstream of the protein citrullination pathway. Inhibition of NET formation reduces the exposure of autoantigens and toxic histones to the extracellular environment, leading to a decrease of proinflammatory mediators and protection of endothelial lining and organ tissue.
