Intervention / Treatment
Detailed Description
The study will be a prospective, single-center, single-arm, intra-subject controlled, open-label design.
Subjects will donate one unit of fresh whole blood. This unit will be treated with the Mirasol PRT System for whole blood and then stored for 24 hours ± 1 hour at 22 ± 2°C. At the end of storage, platelet concentrates will be separated from the unit according to the Biomedical Excellence for Safer Transfusion (BEST) procedures. An aliquot will be removed from the platelet concentrates for testing and for radiolabeling and reinfusion. The platelets in Mirasol-treated whole blood will be tested for key in vitro parameters directly after treatment (Day 0) and at the end of storage (Day 1). Sterility testing will also be conducted on the stored units.
An aliquot of the platelet concentrate separated from each unit of stored Mirasol-treated whole blood will be radiolabeled with either 111Indium Oxine or 51Chromium, and autologously infused. An intra-subject control will be utilized as per the BEST guidelines for platelet radiolabeling procedures. On the day of infusion, the subject will donate a fresh sample of whole blood. Platelets will be separated from this fresh sample and labeled with the radio-isotope that was not used to label the subject's Mirasol-treated platelet sample. The two radiolabeled platelet aliquots (Mirasol-treated and fresh control) will be infused simultaneously, and the recovery and survival of the two types of platelets will be measured according to standard institutional practice.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Platelet 24-hour Relative Recovery
Time Frame: 24 hours
|
Relative recovery of platelets derived from Mirasol-treated whole blood (WB) units that had been stored for 24 ± 1 hours at 22 ± 2ºC, measured as a percentage of platelets derived from freshly collected WB from the same participant.
Platelets were isolated from both Mirasol-treated WB and from fresh WB from the same participant, radiolabeled with either 111Indium or 51Chromium, and these 2 radiolabeled platelet samples (ie, 1 untreated, fresh and 1 Mirasol-treated, stored) were combined and reinfused back to the same participant.

24 hours

Relative Platelet Survival
Time Frame: Days 1 through 10 post-infusion
|
Mean survival time of platelets derived from Mirasol-treated whole blood (WB) units that had been stored for 24 ± 1 hours at 22 ± 2ºC as compared to the mean survival time of fresh platelets from the same donor, measured in hours.
Platelets were isolated from both Mirasol-treated WB and from fresh WB from the same participant, radiolabeled with either 111Indium or 51Chromium, and these 2 radiolabeled platelet samples (ie, 1 untreated, fresh and 1 Mirasol-treated, stored) were combined and reinfused back to the same participant.

pH is a measure of the acidity or alkalinity of a solution, numerically equal to 7 for neutral solutions, increasing with increasing alkalinity and decreasing with increasing acidity.
The pH scale commonly in use ranges from 0 to 14

Hemolysis is the rupture or destruction of red blood cells (RBCs), which releases hemoglobin from inside the RBCs into the plasma (where it is called "free hemoglobin").
Hemolysis is measured as the percentage of free hemoglobin compared to the total hemoglobin in a blood sample.
