Interventions

The purpose of this study is to compare the safety and efficacy of BAY 59-7939 with the saftey and efficacy of enoxaparin and vitamin K-antagonist and to find the optimal dose of BAY 59-7939. Patients with acute symptomatic proximal deep vein thrombosis objectively confirmed by ultrasound examination will be randomized into the study. Patients with symptomatic pulmonary embolism at study entry will be excluded. The patients will be randomized centrally into one of the following five treatment a

The purpose of this study is to compare the safety and efficacy of BAY 59-7939 with the saftey and efficacy of enoxaparin and vitamin K-antagonist and to find the optimal dose of BAY 59-7939. Patients with acute symptomatic proximal deep vein thrombosis objectively confirmed by ultrasound examination will be randomized into the study. Patients with symptomatic pulmonary embolism at study entry will be excluded. The patients will be randomized centrally into one of the following five treatment arms: I: 10 mg bid BAY 59 7939 tablets. II: 20 mg bid BAY 59 7939 tablets. III: 30 mg bid BAY 59 7939 tablets. IV: 40 mg od BAY 59 7939 tablets. V: Enoxaparin sodium injections/vitamin K-antagonist tablets (warfarin, phenprocoumon or acenocoumarol). The dose arms of BAY 59 7939 will be blinded. The active comparator enoxaparin/vitamin K-antagonist will be open labelled. The main treatment period of 21 days is followed by an extended period of trial therapy until week 12 (Day 84). Patients should continue with the extended trial therapy to Day 84 (week 12) after the primary outcome assessment at Day 21 if the locally reported assessment of CCUS and/or perfusion lung scanning indicates no deterioration of either. If there is a locally reported but asymptomatic deterioration of either result, then investigators will apply their clinical judgment to decide if such patients should proceed with the extended period of trial therapy to Day 84 (week 12). A follow-up visit is required 30 days after the last intake of study medication.

Prophylactic doses of UFH or LMWH are allowed).Fibrinolytic agents are not allowed during the study.All other drugs influencing coagulation (exception: NSAIDs with half-life < 17 hours) are not allowed during the study.Systemic and local topical treatment with azole compounds and other strong CYP3A4 inhibitors are not allowed within 4 days prior to randomization and during the study.
