Cerus' INTERCEPT Platelet System Succeeds in 3-Year French Study
CONCORD, Calif.--(BUSINESS WIRE)--Sep 27, 2010 - Cerus Corporation (NASDAQ:CERS) announced today the favorable outcome of a large French study evaluating transfusion of over 13,000 platelet components treated with the INTERCEPT Blood System. The study has just been published online in the journal Transfusion1.
"This study demonstrates that INTERCEPT can be implemented into routine practice, providing protection against transfusion-transmitted pathogens, without impacting either platelet or red blood cell utilization. This observation confirms previous data indicating that the treated platelets are functioning similarly to untreated platelets," said Dr. Laurence Corash, Cerus' chief medical officer. "The investigators also noted that use of INTERCEPT treated platelets resulted in a decrease in the incidence of adverse events following transfusion."
The study was performed by the Etablissement Français du Sang (EFS) of Alsace, France, which is the sole provider of blood components for the region's approximately two million inhabitants. EFS Alsace, which produces approximately 17,000 platelet components per year, implemented production of INTERCEPT platelets in 2006. In order to assess the impact of their conversion to pathogen inactivated platelets, the blood center performed a retrospective analysis of routinely collected active hemovigilance data collected both before and after the change. Collection of hemovigilance data is mandatory in France, and the system is estimated to collect data from over 99% of all transfusions. The study also evaluated the center's introduction of platelet additive solution, which occurred prior to conversion to INTERCEPT. Three periods of data were compared, including in total over 33,000 platelet transfusions to almost 6000 patients.
The EFS Alsace study results are consistent with those reported in several other large post-marketing evaluations of INTERCEPT platelets2-4, and also similar to a previously published multi-year Belgian experience5. Like most INTERCEPT customers, EFS Alsace is able to realize some cost offsets by using the inactivation treatment in place of gamma irradiation for prevention of transfusion-associated graft-versus-host disease, in place of cytomegalovirus testing, and in place of bacterial detection tests.
Cerus Corporation is a biomedical products company focused on commercializing the INTERCEPT Blood System to enhance blood safety. The INTERCEPT system is designed to reduce the risk of transfusion-transmitted diseases by inactivating a broad range of pathogens such as viruses, bacteria and parasites that may be present in donated blood. The nucleic acid targeting mechanism of action allows INTERCEPT treatment to inactivate both established transfusion threats, such as hepatitis, HIV, West Nile virus and bacteria, as well as emerging pathogens such as influenza, malaria and dengue. Cerus currently markets and sells the INTERCEPT Blood System for both platelets and plasma in Europe, Russia, the Middle East and selected countries in other regions around the world, with over 600,000 units transfused to date. The INTERCEPT red blood cell system is in clinical development. Visit http://www.cerus.com for more information.
