A Trial to Investigate the Relative Efficacy, Safety, and Tolerability of Octaplas LG Versus Octaplas SD

Phase 1

Completed

Brief Summary: The primary objective of the study was to compare the efficacy of Octaplas LG with Octaplas SD in terms of recovery of coagulation factors and other haemostatic parameters. The secondary objective of the study was to compare the safety and tolerability of Octaplas LG with Octaplas SD in terms of haematological and clinical chemistry parameters and adverse event monitoring.

Arm && Interventions

Group	Intervention	Description
Octaplas LG	Octaplas LG	Participants received 1200 mL of Octaplas LG intravenously once.
Octaplas SD	Octaplas SD	Participants received 1200 mL of Octaplas SD intravenously once.

Primary Outcome Measures

Name	Time	Method
Recovery of the Haemostatic Parameters Prothrombin Time, Activated Partial Thromboplastin Time, and Protein C	From 5 minutes after the end of plasmapheresis up to 2 hours after the end of study drug administration	Recovery was defined as the maximum (minimum for activated partial thromboplastin time) percentage change of the haemostatic parameter value measured 5 minutes after the end of plasmapheresis to the haemostatic parameter value measured at 15 minutes or 2 hours after the end of study drug administration. The haemostatic parameters were measured by validated assays from blood samples obtained 5 minutes after the end of plasmapheresis and 15 minutes and 2 hours after the end of study drug administration.
Recovery of the Coagulation Factors I, II, V, VII, VIII, IX, X, and XI	From 5 minutes after the end of plasmapheresis up to 2 hours after the end of study drug administration	Recovery was defined as the maximum percentage change of the coagulation factor value measured 5 minutes after the end of plasmapheresis to the coagulation factor value measured at 15 minutes or 2 hours after the end of study drug administration. The coagulation parameters were measured by validated assays from blood samples obtained 5 minutes after the end of plasmapheresis and 15 minutes and 2 hours after the end of study drug administration.

Secondary Outcome Measures

Name	Time	Method
Concentration of Plasmin Inhibitor	From 30 minutes before plasmapheresis up to 24 hours after the end of plasmapheresis	Values of plasmin inhibitor were measured by validated assays from blood samples obtained 30 minutes before plasmapheresis, 5 minutes after the end of plasmapheresis, 15 minutes and 2 hours after the end of study drug administration, and 24 hours and 7 days after initiation of plasmapheresis. The concentration of plasmin inhibitor is reported as the percentage of plasmin inhibition. A higher concentration of plasmin inhibitor results in a higher percentage of plasmin inhibition.
