Brief Summary

The purpose of the full trial is to determine the efficacy and safety of prophylactic dose rivaroxaban to prevent VTE among cancer patients with CVC.

Detailed Description

TRIM-Line is a double blind randomized controlled trial comparing rivaroxaban 10mg po daily vs placebo in patients with active cancer and indwelling CVC. This will involve 9 centers across Canada.
