Clazakizumab has been specially engineered to remove antibody-dependent cell-mediated cytotoxicity and complement-dependent cytotoxicity. Clazakizumab has been administered in clinical trials involving over one thousand patients and has performed well against safety and efficacy criteria with acceptable tolerability in autoimmune diseases.

About Vitaeris

Vitaeris Inc. is a privately held,clinical-stage biopharmaceutical company based in Vancouver,Canada,focused on the development of the anti-interleukin-6 (IL-6) monoclonal antibody clazakizumab for chronic inflammatory diseases. IL-6 is a key cytokine involved in the inflammation of rheumatoid arthritis and is now being implicated in numerous other diseases characterized by chronic inflammation,including solid organ graft rejection. Clazakizumab has been studied in clinical trials involving over one thousand patients worldwide,and was licensed on an exclusive,worldwide basis from Alder Biopharmaceuticals. Vitaeris' shareholders include key founding investor HBM Healthcare Investments,key founder Alder,Vitaeris' co-founders and other private investors. In December 2017,Vitaeris and CSL Limited announced a strategic partnership with option to acquire.
