Safety, Efficacy, and HemovigilanceReduce Patient Risk of Transfusion Transmitted Infection
The INTERCEPT® Blood System for platelets provides robust, broad-spectrum inactivation, reducing the risks of TTI, including sepsis.
Additionally, the INTERCEPT Blood System inactivates donor T-cells, and is an FDA approved alternative to gamma irradiation for the prevention of transfusion-associated graft-versus-host disease (TA-GVHD). The safety and efficacy of INTERCEPT treated platelets (“INTERCEPT Platelets”) has been supported by hemovigilance programs and several clinical trials.
of septic reactions
in routine use
Hemovigilance (HV) programs provide a comprehensive view of transfusions and potential adverse events via the surveillance of blood donations in routine use settings.
Over 875,000 INTERCEPT Platelets have been transfused to patients in these countries, with no reported transfusion-transmitted infections or sepsis-related fatalities to-date.

** Switzerland transitioned to 100% INTERCEPT treated platelets in 2011
*** Belgium transitioned to 100% INTERCEPT treated platelets in 2015
Clinical trials leading to FDA approval
The INTERCEPT Blood System has been evaluated in numerous clinical trials comprised of over 1000 subjects that received INTERCEPT Platelets. Primary endpoints were met in the controlled, randomized clinical trials, including corrected count increments (CCI) and bleeding criteria, both of which are measures of hemostatic efficacy. The frequency of acute transfusion reactions (ATRs) was assessed in three observational studies.
