E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To assess whether rivaroxaban is any better than dalteparin for the treatment of venous thromboembolism in cancer patients. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are as follows: • To assess 6 months and 12 months treatment with rivaroxaban in patients with evidence of residual vein thrombosis (RVT), following initial therapy in terms of VTE recurrence rates. • To assess the VTE recurrence rates in patients with evidence of residual vein thrombosis (RVT) and those with no evidence of RVT. • To assess acceptability and compliance to randomisation and allocated treatment. • To ensure the safety of the patients with regards to major bleeding in an internal safety study. |

E.2.3 | Trial contains a sub-study | No |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Biomarker Sub-study, V1.0 Biomarkers of thrombotic risk include D-dimer, soluble P-selectin, Prothrombin Fragments 1 and 2, C-reactive protein, and tissue factor (TF). Microparticles (MP) are submicron membrane vesicles. They are statistically higher in cancer patients with VTE than those without VTE. Circulating MP harbour molecular information related to cancer-related processes and may serve as a reservoir of prognostic and predictive biomarkers to monitor genetic tumour progression, angiogenesis, thrombosis, and responses to targeted therapies. Experimental pharmacological data in vivo demonstrate that TF-VIIa-PAR2 signalling indeed plays a pivotal role in tumour progression. A broader selection of MP-associated biomarkers bearing highly active procoagulant and pro-fibrinolytic/tissue degradation functions and the resulting balance between pro- and anti-coagulant functions may constitute a powerful biomarker of the hyper- or hypo-coagulant tendency in cancer patients which may prove a powerful screening tool for recurrent VTE in cancer patients. This sub-study will be carried out on 100 patients. Bloods and tissue will be requested at baseline (before any treatment), bloods only at month 3, and blood and tissue (if feasible) at end of treatment. |
|
E.3 | Principal inclusion criteria |

Age 18 years or over and written informed consent given. 5. Adequate haematological function (recommended levels – haemoglobin (Hb) > 10g/dl, white cell count (WCC) > 2x109/l, platelets > 100 x109/l). 6.

Bacterial endocarditis. 6. Active bleeding or a high risk of bleeding, contraindicating anticoagulant treatment. 7. Systolic blood pressure greater than 180 mm Hg or Diastolic blood pressure greater than 110 mm Hg. 8. Of childbearing potential (both male and female participants) without a combination of proper contraceptive measures. 9. Pregnant or breast-feeding. 10.
