Efficacy and Safety Study of Platelets Treated for Pathogen Inactivation and Stored for Up to Seven Days - Full Text View

Sponsor:	Cerus Corporation
Information provided by:	Cerus Corporation
ClinicalTrials.gov Identifier:	NCT00261924

Purpose

Objective: To determine if platelets treated for pathogen inactivation and stored for 6 to 7 days are safe and effective compared to platelets collected by the same method, stored for the same amount of time and not treated for pathogen inactivation.

Study Type:	Interventional
Study Design:	Allocation: Randomized Endpoint Classification: Safety/Efficacy Study Intervention Model: Parallel Assignment Masking: Double Blind (Subject, Caregiver, Investigator) Primary Purpose: Prevention
Official Title:	Clinical Trial to Evaluate the Therapeutic Efficacy and Safety of INTERCEPT Platelets Stored for up to Seven Days After Collection

Arms	Assigned Interventions
Experimental: Intercept Platelets Study patients receiving platelets that have been processed with the INTERCEPT pathogen inactivation system	Device: Transfusion of Pathogen Inactivated Platelets stored for 6-7 days pathogen inactivation of platelets for transfusion Other Name: INTERCEPT
Active Comparator: Conventional Platelets Study patients receiving platelets processed by standard method without the INTERCEPT pathogen inactivation system	Device: Transfusion of Pathogen Inactivated Platelets stored for 6-7 days pathogen inactivation of platelets for transfusion Other Name: INTERCEPT

Detailed Description:

Although the European Commission directive 2004/33/EC states that platelet preparations may be stored for 7 days in conjunction with detection or reduction of bacterial contamination, most blood centers store platelets for only 4 or 5 days. Extending the storage time could greatly improve platelet availability for patients while decreasing wastage of this limited resource.
