10. Major bleeding episode (reduction in the haemoglobin level of at least 2 g/dL, transfusion of at least two units of blood, or symptomatic bleeding in a critical area or organ) including life-threatening bleeding episode (symptomatic intracranial bleeding, bleeding with a decrease in the haemoglobin level of at least 5 g/dL or bleeding requiring transfusion of at least 4 units of blood or inotropic agents or necessitating surgery) in one month prior to screening visit;
11. Haemorrhagic disorder or bleeding diathesis (e.g. von Willebrand disease, haemophilia A or B or other hereditary bleeding disorder, history of spontaneous intra-articular bleeding, history of prolonged bleeding after surgery/intervention);

(Acceptable methods of birth control are oral or parenteral (patch, injection, implant) hormonal contraception which has been used continuously for at least one month prior to the first dose of study medication, intrauterine device or intrauterine system, double-barrier method of contraception (condom and occlusive cap or condom and spermicidal agent), male sterilization and complete sexual abstinence (if acceptable by local authorities)). Periodic abstinence is not an acceptable method of contraception.
