What is Extracorporeal Photopheresis (ECP)?


Extracorporeal Photopheresis, also known as ECP, is a treatment that works with the immune system.

ECP stands for extracorporeal photopheresis – a light-activated treatment performed on temporarily separated blood cells outside the body. It is used to treat a range of immune-mediated diseases.

The exact way ECP works is unknown.

Our THERAKOS™ CELLEX™ Photopheresis System performs ECP using patented technology that collects, separates and treats a small amount of white blood cells (immune cells) while the patient is connected to the instrument.

Please refer to the Important Safety Information for more details.
