Study of Octaplex (Human Prothrombin Complex Concentrate) and Fresh Frozen Plasma in Patients Under Vitamin K Therapy Antagonist Needing Urgent Surgery or Invasive Procedures

The primary objective of the study is to demonstrate that the efficacy of Octaplex as a reversal agent in patients under vitamin K antagonist therapy with the need for urgent surgery or invasive procedures was not clinically inferior to that of FFP.

The secondary objective of the study is to investigate the safety and tolerability of Octaplex compared to FFP in patients under vitamin K antagonist therapy with the need for urgent surgery or invasive procedures.
