Study
 will test clinical effectiveness of standard versus pathogen-reduced 
platelet concentrates with potential benefit to patients
LAKEWOOD, Colo. - Wednesday, February 13th 2013 [ME NewsWire]
(BUSINESS
 WIRE)-- Terumo BCT announces that the first patient, in the ongoing 
PREPAReS (Pathogen Reduction Evaluation & Predictive Analytical 
Rating Score study) trial, has been enrolled in Canada. Sponsored by the
 Sanquin Blood Supply Foundation, Netherlands, this international study 
is designed to compare the effectiveness of standard platelets versus 
platelets treated with the Mirasol system to prevent bleeding in a 
variety of patient populations.
While blood donations are 
commonly screened for specific pathogens to minimize risks for 
transmitting infectious disease, the Mirasol system is designed to 
further enhance the safety of platelet and plasma transfusions by using a
 combination of riboflavin (vitamin B2) and ultraviolet (UV) light to 
inactivate viruses, bacteria, parasites and white blood cells that might
 be present in collected blood products. The system is intended to 
produce a treated product to benefit patients receiving platelet and 
plasma products worldwide.
KEY FACTS:
    The PREPAReS 
trial is a non-inferiority, single-blinded study designed to compare the
 clinical efficacy of Mirasol (riboflavin/vitamin B2)-pathogen-reduced 
platelet concentrates with standard platelet concentrates using 
clinically relevant end points.
        The first patient was enrolled in Canada in January 2013
       
 The study began patient accrual in November 2010 in the HAGA hospital 
(the Hague, Netherlands) and currently has 173 participating patients.
        In addition to Canada, four Dutch transfusion centers are participating in the study.
        The study is estimated to complete enrollment by late 2013 or early 2014.
    An estimated 10 million platelet units are transfused to patients in North America, Europe and Asia each year.
   
 Experts estimate that as many as one in every 2,000 units of platelets 
collected could contain bacteria. Inactivating bacteria that might be 
present in collected platelets may be of benefit to patients receiving 
platelet transfusions, as bacterial contamination in platelets 
represents the single greatest infectious risk in transfusion medicine 
today.
KEY QUOTES:
Ray Goodrich, Ph.D., Terumo BCT, Vice President of Scientific and Clinical Affairs
“We
 have worked very closely with Sanquin, Canadian Blood Services and 
Health Canada on the Canadian arm of the PREPAReS Trial. The trial has 
been designed to establish that Mirasol-treated platelets are comparable
 to untreated platelets, in terms of efficacy for patients requiring 
platelet transfusion support. The study is also designed to determine if
 the use of Mirasol-treated platelets reduces the risk of 
HLA-alloimmunization in patients who require transfusions.”
Jean-Louis Kerkhoffs, Sanquin Blood Supply Foundation
“Safe
 and effective platelet transfusions are essential in the supportive 
care of hematology patients. Scientists, hematologists and transfusion 
specialists as well as numerous other dedicated colleagues are 
collaborating on the PREPAReS study, a unique transatlantic experience 
to further improve the safety of platelet transfusions and the care for 
hematology patients.”
Dana Devine, Vice President, Medical, Scientific & Research Affairs, Canadian Blood Services
“Canadian
 Blood Services is very pleased that this trial is under way. We look 
forward to the day that pathogen reduction technologies for treatment of
 cellular blood products are available for use in Canada. This trial is a
 first step toward licensure of this technology in Canada.”
