Title: A Phase III, Randomized, Open Label Study Evaluating the Safety of Apixaban in Subjects With Cancer Related Venous Thromboembolism
Brief Summary: This randomized phase III trial studies the side effects of and compares apixaban and dalteparin in reducing blood clots in patients with cancer-related venous thromboembolism. Venous thromboembolism is a condition in which a blood clot forms in a vein and then breaks off and moves through the bloodstream. Patients with cancer are at increased risk for venous thromboembolism. Apixaban and dalteparin are drugs used to prevent blood clots from forming or to treat blood clots that have formed. It is not yet known whether apixaban or dalteparin is more effective in reducing blood clots in patients with cancer related venous thromboembolism.

Examples may include unwarranted radiation exposure as a result of a repeat CT scan at day 84 for a patient with an isolated case of pulmonary embolism evaluated at baseline solely by a CT scan. In such cases, the baseline radiological assessment (e.g. CT) may be supplemented with an acceptable non-radiological assessment at baseline (e.g. MRI) which could then be repeated at day 84 hence alleviating any potential unwarranted radiation exposure.
* Further exclusion criteria apply
