Each subject will be infused with an aliquot of autologous radiolabeled INTERCEPT-treated (Test) or untreated (Control) AS-1 RBCs. During the study period each study subject will donate a whole blood (WB) component which will be processed to produce a leukocyte reduced AS-1 RBC component. Depending on the randomization assignment of the subject (Test or Control) the RBCs in AS-1 will be processed as a Test component (either within 24 hours or 25-48 hours of collection, depending on randomization) or Control component. On Day 35, an aliquot (10-30 mL) of study RBCs will be aseptically removed from the Test or Control RBC component and radiolabeled with 51Cr for assessment of recovery and lifespan.\n\nOn Day 35, the same healthy subjects will return to the site and provide a fresh sample of heparinized blood (approximately 10 mL), the fresh autologous RBCs from this sample will be radiolabeled with 99mTc for measurement of blood volume.\n\nThe 51Cr (Test or Control) and 99mTc (fresh RBCs) radiolabeled samples (approximately 10-30 mL) will be simultaneously infused into the subject. To measure RBC recovery and blood volume, subject blood samples will be collected at the following time points after completion of the infusion: approximately 5, 7.5, 10, 12.5, 15, 20, and 30 minutes (Day 35) and at 24 ±4 hours (Day 36). To measure the RBC lifespan post infusion, additional subject blood samples will be collected. 51Cr activity will be measured at approximately 48 hours (Day 37), 72 hours (Day 38), 7 days (Day 42) post-infusion, and then weekly through 35 days post-infusion (approximately Days 49, 56, 64, and 70) for Test and Control subjects. For Test subjects, as an additional measure of circulating INTERCEPT RBCs, the proportion of acridine positive RBCs and level of acridine on Test RBCs will be evaluated. Post-infusion RBC samples will be frozen at approximately 30 minutes on Day 35 and on Days 36, 37, 38, 42, 49, 56, 64, 70, and 90.\n\nSubjects will be monitored for adverse events (serious and non-serious) for 24 hours following the WB donation and approximately 24 hours following infusion of study RBCs. Only serious and treatment emergent adverse events, including transfusion reactions, will be assessed at subsequent post-infusion visits.\n\nSamples for in vitro RBC testing (see in vitro evaluation of RBCs below) will be collected from RBC components at input, post-INTERCEPT (Test only), and after 35 days of storage (Test and Control).",[19],"Healthy Subjects",[21,22,23,24,25,26,27,28,29,30],"INTERCEPT","Red Blood Cells","RBC","Pathogen Inactivation","Pathogen reduction","Cerus","Survival","Radiolabel","Autologous","Recovery","INTERVENTIONAL","OTHER",[34],"PHASE2",{"count":36,"type":37},70,"ESTIMATED",[39,45],{"type":40,"name":41,"description":42,"armGroupLabels":43},"DEVICE","INTERCEPT Blood System for RBCs","RBCs treated with the INTERCEPT Blood System for RBCs",[44],"Test RBCs will be prepared with the INTERCEPT Blood System for RBCs",{"type":32,"name":46,"description":47,"armGroupLabels":48},"Infusion of autologous radiolabeled RBCs","Subject will receive a single intravenous infusion of approximately 10 to 30 mL of autologous Day 35 51Cr radiolabeled RBCs and fresh 99mTc RBCs.",[49,44],"Control RBC components will be prepared according to the site standard operating procedures",[51],{"measure":52,"description":53,"timeFrame":54},"The percentage of infused 35-day-old autologous 51Cr-labeled Test\u002FINTERCEPT or Control RBCs remaining in circulation 24 hours post-infusion","The 24-hour recovery will be calculated using the subject's blood volume derived from infusion of 99mTc-labeled fresh RBCs.","Pre-transfusion and 5, 7.5, 10, 12.5, 15, 20, and 30 minutes and at 24 hours after infusion",[56,59,63],{"measure":57,"description":58,"timeFrame":54},".
