Assess the safety of single infusions with RePlas FDP product at increasing fixed doses
This is a single-site, partial double-blind study in healthy volunteers designed to assess the safety of infusing ascending doses of reconstituted autologous freeze dried plasma (FDP) in 3 fixed-dose cohorts. Beginning with Cohort 1, subjects will receive a single infusion of 1 unit (approximately 270 mL) of either FDP manufactured from fresh frozen plasma (FFP) derived from autologous whole blood (WB) collection(s) that use citrate phosphate dextrose (CPD) as the anticoagulant (FDP-CPD) or FDP manufactured from FFP units from autologous plasmapheresis where acid citrate dextrose (ACD) is used as the anticoagulant (FDP-ACD). Recruitment of subjects for Cohort 2 follows the completion of infusions in Cohort 1. Subjects in Cohort 2 will receive a single infusion of 2 units (approximately 540 mL) of either FDP-CPD or FDP-ACD before recruitment for Cohort 3 is initiated. Subjects enrolled in Cohort 3 will receive the highest study dose, a plasma infusion dose of 3 units (approximately 810 mL) of FDP-ACD at one infusion visit and the same dose of autologous FFP at another infusion visit. Cohort 3 subjects will only be infused with FDP and FFP products sourced from autologous plasmapheresis. Randomization of Cohort 3 subjects to a treatment sequence determines whether they will be infused with 3 units of FDP or 3 units of FFP at their first infusion visit followed by infusion with the alternate product at the second infusion visit. A 2-week interval will be maintained between infusion visits in Cohort 3. Crossover of FDP and FFP enables comparison of infusion safety and select coagulation factor recoveries within the same subjects between FDP and FFP at this higher dose.

Safety of Single Infusions of FDP at Increasing Fixed Doses in Normal Healthy Subjects by Evaluating Vital Signs and Laboratory Tests
Assess the safety of single infusions of FDP at increasing fixed doses of either 1 unit, 2 units, or 3 units in normal healthy subjects by evaluating vital signs during and after infusion
Time frame: Follow-up assessments on days 2, 8, 29, and telephone assessments on days 3 and 4
Number of Participants With Treatment-emergent Adverse Events
Assess the safety and tolerability of a fixed-dose infusion of 3 FDP units in comparison to infusion with the same dose of autologous Fresh Frozen Plasma (FFP) in normal healthy subjects by evaluating vital signs and laboratory tests
Time frame: Follow-up assessments on days 2, 8, 16, 22, 43, and telephone assessments on days 3, 4, 17, and 18
Number of Participants With Significant Changes in Specific Coagulation Values
Determine if the changes in specific coagulation values are similar with clinically meaningful levels pre and post infusion in the different arm groups by evaluating laboratory tests. Blood thrombin, Coombs direct test, Fibrin D dimer, and Thrombin-antithrombin III levels are determined through a blood test to check if your blood is clotting normally. Positive tests or any values below or above the normal reference range is considered abnormal.
Time frame: For cohorts 1 and 2, follow-up assessments on days 2, 8 and 29. For cohort 3, follow-up assessments on days 2, 8, 16, 22, and 43.
Number of Participants With Significant Changes in Specific Hematology Values
Determine if the changes in specific hematology values are similar with clinically meaningful levels pre and post infusion in the different arm groups by evaluating laboratory tests. The specific hematology values are determined through a blood test. Any values below or above the normal reference range is considered abnormal.
Time frame: For cohorts 1 and 2, follow-up assessments on days 2, 8 and 29. For cohort 3, follow-up assessments on days 2, 8, 16, 22, and 43.
Number of Participants With Significant Changes in Specific Chemistry Values
Determine if the changes in specific chemistry values are similar with clinically meaningful levels pre and post infusion in the different arm groups by evaluating laboratory tests. Glucose levels and liver function levels, ALT and AST, are determined through a blood test. Any values below or above the normal reference range is considered abnormal.
Time frame: For cohorts 1 and 2, follow-up assessments on days 2, 8 and 29. For cohort 3, follow-up assessments on days 2, 8, 16, 22, and 43.
Healthy volunteers were recruited at an academic medical center between February 2017 and March 2018. The first participant was enrolled on March 6, 2017 and the last participant was enrolled on April 5, 2018.
