Cytos Biotechnology GmbH was founded in February 1995 by Dr. Wolfgang A. Renner, the late Prof. Dr. James E. Bailey, and Prof. Dr. Hans M. Eppenberger as a spin-off company of the Swiss Federal Institute of Technology (ETH) in Zurich, Switzerland. The company was transformed into a privately owned Swiss corporation in July 1998 (Aktiengesellschaft). In October 2002, Cytos Biotechnology completed its take-over of Asklia Holding AG. As a consequence, Cytos Biotechnology Ltd was publicly listed on the main board of the SIX Swiss Exchange on October 29, 2002 (SIX:CYTN).
