Effect of BIBT 986 Followed by BIBT 986 Given as IV Infusion on Tissue Factor Triggered Coagulation in Healthy Male Volunteers

7 de outubro de 2014 atualizado por: Boehringer Ingelheim

Investigation of the Effect of 0.9, 2.25 or 4.5 mg of BIBT 986 Over 1 Hour, Followed by 0.2, 0.5 or 1.0 mg/Hour of BIBT 986 for 7 Hours Given as IV Infusion on Tissue Factor Triggered Coagulation in a Randomised, Placebo Controlled, Dose Escalation Design in Healthy Male Volunteers

To compare with placebo the anticoagulant activity of three dosages of BIBT 986 on parameters of coagulation, platelet activation and inflammation in a model of tissue factor triggered activation of the coagulation system; to examine the safety of BIBT 986 in this setting
