CITRYLL,  Innovation in Medicine

Job opportunities at Citryll

Senior Research Associate(s) Cell Biology and Pharmacology


Citryll is a biotech company, located in the Pivot Park in Oss, The Netherlands. Citryll is taking a new approach to treat autoimmune and other human diseases like Systemic Lupus Erythematosus (SLE), Rheumatoid Arthritis (RA), and others by specifically extinguishing the source of autoimmunity 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) 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. We believe that drugs that block NET-based autoantigen production have the potential to create game changing new treatments to prevent or treat autoimmune diseases, including SLE and RA.

Citryll has now nominated clinical development candidate CIT-013 and is developing CIT-013 towards proof of concept SLE phase 1b clinical studies. The laboratory activities in Oss include the development and optimization of biomarker assays for monitoring the clinical trial, cellular pharmacology and detailed mechanism of action studies as well as studying new therapeutic applications.
