Stored red blood cell viability is maintained after treatment with a second-generation S-303 pathogen inactivation process.

Background: Transfusion-transmitted infections and immunologic effects of viable residual lymphocytes remain a concern in red blood cell (RBC) transfusion. Pathogen reduction technologies for RBC components are under development to further improve transfusion safety. S-303 is a frangible anchor-linker-effector with labile alkylating activity and a robust pathogen reduction profile.

A multi-centre study of therapeutic efficacy and safety of platelet components treated with amotosalen and ultraviolet A pathogen inactivation stored for 6 or 7 d prior to transfusion.

Bacteria in platelet components (PC) may result in transfusion-related sepsis (TRS). Pathogen inactivation of PC with amotosalen (A-PC) can abrogate the risk of TRS and hence facilitate storage to 7 d. A randomized, controlled, double-blinded trial to evaluate the efficacy and safety of A-PC stored for 6-7 d was conducted.

An active hemovigilance program characterizing the safety profile of 7483 transfusions with plasma components prepared with amotosalen and UVA photochemical treatment.

Background: Photochemical pathogen inactivation treatment (PCT) of plasma components with amotosalen and UVA has been implemented in Europe. To establish a postapproval safety database, an active hemovigilance (HV) program utilizing an electronic data capture system (EDCS) was initiated.

Study Design And Methods: The response to transfusion was documented after each PCT-plasma transfusion.
