Brief Summary:
This is a multicentre, prospective, randomised, double-blinded, group-sequential, parallel-group, adaptive design, phase 3 study to demonstrate the haemostatic efficacy and safety of four-factor prothrombin complex concentrate, OCTAPLEX, in patients with acute major bleeding on DOAC therapy with factor Xa inhibitor. Patients will be randomised 1:1 to either of two study groups: low-dose vs. high-dose OCTAPLEX.

Criteria
Inclusion Criteria:
- Patients who received or who are believed by the investigator to have received a dose of oral factor Xa inhibitor
- Aged ≥18 years
- Patients who have given written informed consent or for whom written informed consent has been obtained from the patient's legally authorised representative on their behalf
-
Patients who have acute major bleeding defined as follows:
- Bleeding that is potentially life-threatening or uncontrolled, e.g., with signs or symptoms of haemodynamic compromise, such as severe hypotension, poor skin perfusion, or low cardiac output that cannot be otherwise explained OR
- Symptomatic bleeding in critical organs (intracranial, intraspinal, intraocular, retroperitoneal, intra-articular, pericardial, or intramuscular with compartment syndrome) OR
- Acute overt bleeding associated with a fall in haemoglobin (Hgb) level of ≥2 g/dL, OR a Hgb level ≤8 g/dL if no baseline Hgb level is available, OR in the opinion of the investigator that the patient's Hgb level will fall to ≤8 g/dL with resuscitation
- Patients with baseline anti-factor Xa activity equivalent to at least 100 ng/mL according to the available test (e.g., chromogenic assay)
Exclusion Criteria:
- Patients with bleeding that is immediately life-threatening
- Patients with 'Do not resuscitate' (DNR) orders
- Patients with acute trauma for which reversal of DOAC therapy with factor Xa inhibitor alone would not be expected to control the bleeding event
- Hgb decrease without accompanying evidence of source of bleeding
- Acute coronary syndrome, ischaemic stroke or venous thromboembolism (VTE) within the preceding 3 months
- Patients with a history, within the last 3 months, of disseminated intravascular coagulation (DIC) or hyperfibrinolysis
- Patients with a known congenital bleeding disorder
- Known inhibitors to coagulation factors II, VII, IX, or X; heparin-induced, type II thrombocytopenia; or immunoglobulin A (IgA) deficiency with known antibodies against IgA
- Known hypersensitivity to plasma-derived products
- Patients who received haemostatic agents, including plasma, platelets, PCC, activated PCC (aPCC), recombinant factor VIIa, or recombinant factor Xa inactivated-zhzo (andexanet alfa), for the current bleeding event prior to enrolment (antifibrinolytic drugs and local haemostatic agents are allowed)
- Patients who received ticlopidine within 14 days, prasugrel within 7 days, clopidogrel within 5 days, ticagrelor within 5 days or cangrelor within 1 hour preceding the bleeding event
- Patients on enoxaparin therapy for thromboembolic prophylaxis
- A score of less than 7 on the Glasgow Coma Scale or an estimated intracerebral haematoma volume of more than 60 mL
- Patients with expected survival of less than 3 days
- Patients scheduled to undergo surgery in less than 12 hours, with the exception of some minor/invasive procedures that are allowed for diagnostic or therapeutic reasons
- Patients who are pregnant or breastfeeding at the time of enrolment
- Patients previously enrolled in this study
- Patients participating in another interventional clinical treatment study currently or during the past 1 month prior to study inclusion
