TRIM-Line: Primary Thromboprophylaxis in Patients With Malignancy and Central Venous Catheters
Study Details
Study Description
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.
| Condition or Disease | Intervention/Treatment | Phase |
|---|---|---|

Phase 3 |
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.
