Summary

The principle 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 autologous radiolabeled 7 day INTERCEPT platelets (Test) stored in 100% plasma will be measured in comparison to "fresh" autologous radiolabeled platelets (Control) according to FDA guidance for platelet testing (FDA 1999) in Stage 2 of this study protocol.

A secondary objective is to compare the recovery and survival results for Test platelets prepared for radiolabeling using the procedures outlined by the Biomedical Excellence for Safer Transfusion Collaboration (BEST) or a variation of the BEST procedure (referred to as Variant 1) in Stage 1 of this study protocol. Cerus has demonstrated that the Variant 1 method, which does not incorporate an initial soft spin in the presence of ACD A, results in improved in vitro platelet recovery and quality during preparation for radiolabeling compared to the BEST procedure. This comparison will evaluate the hypothesis that preparation methods prior to radiolabeling may influence in vitro quality of the radiolabeled platelets and post-infusion viability outcomes.

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 7days at 20-24°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 (approximately 10-30 mL) will be simultaneously administered intravenously into the subject.
