Conditions

Venous Thromboembolism, Cancer

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.
