“In Vivo Study to Assess the Recovery and Survival of Radiolabeled Autologous INTERCEPT Apheresis Platelet Components Suspended in 100% Plasma Stored for up to 7 Days”
The objective of this study is to evaluate the hypothesis that INTERCEPT Platelets in 100% plasma stored for 5 or more days (up to 7 days) after apheresis collection retain sufficient viability for therapeutic transfusion efficacy. The post infusion recovery and survival of radiolabeled 7, 6 or 5- day INTERCEPT platelets (Test) stored in 100% plasma will be measured in comparison to their "fresh" radiolabeled platelet (Control) according to FDA guidance for platelet testing (FDA 1999).
Device - INTERCEPT Treated Platelets
Apheresis platelet components in 100% plasma collected using the Trima separator, prepared with the INTERCEPT Blood System for Platelets (Test Platelets) and stored for 7, 6 or 5 days at 20Â°C-24Â°C with continuous agitation. Samples from the Test component will be processed with either the BEST or the Variant 1 procedure prior to radiolabeling. The radiolabeled autologous Test and Control platelets will be simultaneously administered intravenously into the subject.
