Using a Blood Test and Software Tool to Guide Treatment for Venous Thromboembolism
Trial Parameters
Brief Summary
The purpose of this study is to find out whether a software tool, ctDNA/VTE (Venous Thromboembolism) risk score model, is an effective way to predict the likelihood of VTE coming back in people who have received anticoagulant treatment.
Eligibility Criteria
Inclusion Criteria: * Age ≥ 18 with a history of cancer-associated VTE (objectively confirmed symptomatic or incidental/unsuspected proximal lower-limb DVT, symptomatic pulmonary embolism \[PE\] or incidental PE in a segmental or more proximal pulmonary artery) and completion of between 3 and 12 months of anticoagulation with a therapeutic dosing of enoxaparin, dalteparin,rivaroxaban, or apixaban without current VTE-related symptoms (imaging to confirm resolution not required). Diagnosis of DVT requires evidence of one or more filling defects at compression ultrasonography, venography, CT venography, or MR venography involving at least the popliteal or more proximal veins. Diagnosis of PE requires an intraluminal filling defect in segmental or more proximal arteries. * Diagnosis of one of the following solid tumors in either advanced (i.e. unresectable) stage or receiving systemic anticancer treatment within six weeks of enrollment (maintenance therapy included): * breast cancer regard
