Assessment
Primary outcomes rate of thrombus resolution
Key secondary outcomes ・ Onset/exacerbation of symptomatic pulmonary embolism (PE)
・ Onset/exacerbation of symptomatic deep vein thrombosis (DVT)
・ Major bleeding event (ISTH bleeding criteria)
・ Non-major bleeding event (bleeding events that do not correspond to major bleeding)
・ Recurrence/exacerbation of symptomatic venous thromboembolism or bleeding event during the initial strengthening treatment period
・ Acute coronary syndrome
・ Cerebral infarction
・ VTE related death
・ Cardiovascular death
・ All deaths
・ Relationship between change in D-dimer and recurrence
・ Relationship between blood levels of anti-factor Xa activity, rate of thrombus resolution, and bleeding events
・ Comparison of examples of treatment continuation/discontinuation or termination events
・ Serious adverse events
・ Relationship between changes in bronchial artery diameter and improvement in pulmonary function as quantitatively assessed using Iodine Density Perfusion Maps
・ Relationship between computed tomography parameters and rate of thrombus resolution
・ Relationship between evaluation of Radwisp and pulmonary thromboembolism patients
