Senior Technician(s) Immunology, Cell Biology & Pharmacology
Citryll is a young and dynamic company, located at the Pivot Park in Oss, The Netherlands. Citryll is taking a new approach to treat human diseases including autoimmune diseases like Systemic Lupus Erythematosus (SLE), Rheumatoid Arthritis (RA), and others by specifically extinguishing the source of autoimmunity and organ damage instead of broadly suppressing the acquired chronic inflammation.
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 binds to N-terminal citrullinated epitopes on histones present in NETs and 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.
Citryll has nominated a clinical development candidate CIT-013 that is being developed towards a proof of concept phase 1b clinical study which is scheduled to enter clinical development in 2021.
In Oss, the birthplace of many blockbuster drugs including the most successful PD1 antagonist antibody, we conduct various R&D elements of the CIT-013 programme. This includes mechanism of action studies, research on new therapeutic uses, bioanalytical assay development, clinical sample testing and pharmacological studies on patient neutrophils and whole blood.
