Dedicated to the practice and technological advancement of ECP for over 30 years

In 1987, we pioneered ECP treatment with the launch of our unique and innovative THERAKOSTM UVAR XTSTM System, which gained FDA approval the following year. Since then, we have been the only providers of fully integrated and validated ECP systems.

Our current platform, the THERAKOSTM CELLEXTM Photopheresis System, first arrived in 2009. It has since been used to deliver over 1 million treatments and is used in over 300 treatment centres across 30 countries.2
