Title: Oral Direct Factor Xa Inhibitor Rivaroxaban in Patients With Acute Symptomatic Deep-Vein Thrombosis or Pulmonary Embolism
Brief Summary: This is a multicenter, randomized, open-label, assessor-blind, event-driven, non-inferiority program for efficacy with a study treatment duration of 3, 6 or 12 months in patients with confirmed acute symptomatic pulmonary embolism (PE) with or without symptomatic Deep-Vein Thrombosis (DVT) (Einstein-PE).


Options:
A: Inclusion Criteria:

1. Hospitalized medical patients 70 years of age or older
2. Acute medical illness with significant decrease in mobility expected for at least 4 days (patient bedridden or only able to walk short distances)
3. written informed consent

Exclusion Criteria:

1. immobilization longer than 3 days prior to randomization
2. prior major surgery, trauma or invasive procedure within the last 4 weeks including any injuries or operation of central nervous system
3. expected major surgical or invasive procedure within the next 3 weeks after randomization
4. LMWH/heparin administration longer than 48 hours in the 5 days prior to randomization
5. immobilization due to cast or fracture
6. indication for anticoagulatory or thrombolytic therapy
7. acute symptomatic DVT / PE
8. known hypersensitivity to any of the study drugs or drugs with similar chemical structures
9. Acute or history of heparin induced thrombocytopenia type II (HIT II)

Other protocol-defined inclusion/exclusion criteria may apply

D: Inclusion Criteria:

* Confirmed acute symptomatic proximal PE with or without symptomatic DVT

Exclusion Criteria:
