1 Massive confirmed pulmonary embolism (PE) with haemodynamic instability at trial entry
2 Indication for therapeutic dosages of anticoagulants at trial entry
3 Mechanical ventilation for longer than 48 hours
4 Chronic pulmonary disease i.e. with known forced expiratory volume in 1 second (FEV1) <50% requiring home oxygen, or oral steroid therapy or hospitalisation for exacerbation within 12 months, or significant chronic pulmonary disease in the Investigatorââ?¬•s opinion, or primary pulmonary arterial hypertension
5 Has a Do-Not-Intubate (DNI) or Do-Not-Resuscitate (DNR) order
6 In the opinion of the investigator, is not expected to survive for > 48 hours after screening.
7 Planned interventions during the first 5 days after randomisation, such as surgery, insertion of central catheter or arterial line, drains, etc
8 Further criteria apply to exclude patients at higher risk of bleeding

- Primary Outcome Measures
Name Time Method Time to clinical improvement or hospital discharge <br/ ><br> <br/ ><br>Time from randomisation to either an improvement of two points on the 11-point WHO Clinical Progression Scale or discharge from the hospital, whichever comes first. The WHO Clinical Progression Scale ranges from 0 to 10. A higher score indicates a worsening of the patient statusTimepoint: Up to day 28
- Secondary Outcome Measures
Name Time Method All cause mortalityTimepoint: At Day 28;Length of hospital stayTimepoint: Up to Day 28;Major bleeding events (MBE)Timepoint: Up to Day 6;Number of oxygen-free daysTimepoint: Up to Day 28;PaO2/FiO2 ratio (or inferred PaO2/FiO2 ratio from SpO2) change <br/ ><br>PaO2: partial oxygen pressure in arterial blood FiO2: fraction of inspired oxygen SpO2: Oxygen saturationTimepoint: From baseline to end of Day 6;Treatment failureTimepoint: At Day 28
