Therakos ECP ImmunomodulationTM
What is Therakos ECP Immunomodulation™?
Extracorporeal photopheresis (ECP)
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 fully integrated and validated ECP system, the THERAKOS™ CELLEX™ Photopheresis System2
The procedural steps3
- 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
- A photosensitising agent* is added to the buffy coat fraction† and cells are photoactivated by UVA 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 the photosensitising agent 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.1,4-7
Take a short journey into the body and explore in depth the proposed immunomodulatory mechanisms that lead to clinical effects.
The mechanisms by which 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), chronic lung allograft dysfunction-bronchiolitis obliterans syndrome (CLAD-BOS) and after cardiac transplantation.2,8-19
