WHAT IS THERAKOS ECP IMMUNOMODULATIONTM?
Extracorporeal photopheresis (ECP) – the basics
Extracorporeal photopheresis (ECP) is an immunomodulatory therapy that has demonstrated efficacy in various T-cell and immune-mediated diseases.1
Unlike immunosuppressive therapies, ECP has not been associated with an increased incidence of infections.2
Please refer to the Important Safety Information for more details.
HOW IS THERAKOS ECP IMMUNOMODULATIONTM DELIVERED?
THERAKOS ECP ImmunomodulationTM is delivered via a completely closed, integrated ECP platform, the THERAKOS™ CELLEX™ Photopheresis System
The procedural steps

- The instrument collects a small fraction of blood from the patient
- The blood is separated by centrifugation
- Red blood cells and plasma are returned immediately to the patient
- Methoxsalen* is added to the buffy coat fraction† and cells are photoactivated by ultraviolet A light
- The photoactivated buffy coat fraction† is reinfused to the patient
Please refer to the appropriate operator’s manual for further details prior to prescribing ECP therapy.
*Exact mechanism of action (MoA) of methoxsalen is unknown.
†The buffy coat fraction of a whole blood sample following centrifugation contains most of the white blood cells and platelets.
HOW DOES IT WORK?
THERAKOS ECP Immunomodulation™ employs the patient’s own immune cells to modulate dysregulated immune function.1,3-6
Take a short journey into the body and explore in depth the proposed immunomodulatory mechanisms that lead to clinical effects.
The mechanisms by which extracorporeal photopheresis (ECP) exerts its clinical effects are under continual investigation to be more fully understood.

WHAT ARE THE
CLINICAL APPLICATIONS?
ECP is recommended by international and national guidelines for
a spectrum of diseases, including cutaneous T-cell lymphoma (CTCL),
acute and chronic graft-versus-host disease (aGvHD and cGvHD),
systemic sclerosis (SSc), lung allograft rejection and after cardiac
transplantation.2,7-13
