Design outcomes

Primary

MeasureTime frame
Main Objective: To investigate the optimal therapeutic dose by evaluation of the efficacy of YM150 in subjects undergoing elective primary hip replacement (HR) surgery. Evaluation of the safety of YM150 in the target population.;Secondary Objective: ;Primary end point(s): Primary efficacy endpoint: - Rate of total venous thromboembolism (VTE) during hospitalization phase (up to Day 7-10) • Deep vein thrombosis (DVT) proven by bilateral venography and/or • Symptomatic DVT and/or • Pulmonary embolism Primary safety endpoint: -Incidence of clinically relevant bleedings during 7-10 days hospitalization treatment rated as Major bleeding.
