Clinical Trial Summary

The Valeria trial will provide high-quality evidence regarding the efficacy and safety of oral rivaroxaban in thromboprophylaxis after gynecological pelvic cancer surgery in comparison with standard parenteral enoxaparin.

Description:

Cancer-associated thrombosis is the second leading cause of mortality in cancer patients, mainly due to the most common complication, venous thromboembolism (VTE). New oral antithrombotic strategies for VTE prevention after gynecological cancer surgery might be non-inferior to parenteral low-molecular-weight heparin (LMWH) in efficacy and safety with increased adherence, comfort, and reduced costs.

This is a multicenter, open-label, prospective, randomized, active-controlled study, and non-inferiority trial. Four hundred and forty patients submitted to major gynecological cancer surgery will be randomized in a 1:1 ratio to receive either oral rivaroxaban 10 mg once daily or subcutaneous enoxaparin 40mg once daily for 30 days post-operative. The primary efficacy outcome is a combination of symptomatic VTE and VTE-related death or VTE detected by mandatory Doppler ultrasound on day 30±4 post-operative. The primary safety outcome is the incidence of major and clinically relevant non-major bleeding according to the International Society on Thrombosis and Hemostasis criteria.

Eligibility

Inclusion Criteria:

• Female patients 18 years of age or older

• Use of strong inhibitors of cytochrome P450 (CYP) 3A4 and/or glycoprotein P (P-gp) (eg, protease inhibitors, ketoconazole, Itraconazole) and/or use of P-gp and strong inducers of CYP3A4 (how but not limiting rifampicin/rifampicin, rifabutin, rifapentine, phenytoin, phenobarbital, carbamazepine or St. John's wort)

Related Conditions & MeSH terms

• Cancer
• Rivaroxaban
• Thromboembolism
• Thromboprophylaxis
• Venous Thromboembolism

Intervention

Drug:
• Rivaroxaban
Patients will be submitted to an initial screening evaluation during hospitalization. At discharge, they will be randomized and enrolled to be treated with oral rivaroxaban (10 mg once daily, for 30 days), once randomized to this group. A mandatory lower limb Doppler ultrasound will be carried out on day 30±4 as part of the primary efficacy endpoint. A final follow-up phone call visit will be performed on day 60 postoperative.
• Enoxaparin
Patients will be submitted to an initial screening evaluation during hospitalization. At discharge, they will be randomized and enrolled to be treated with subcutaneous enoxaparin (40 mg once daily, for 30 days), once randomized to this group. A mandatory lower limb Doppler ultrasound will be carried out on day 30±4 as part of the primary efficacy endpoint. A final follow-up phone call visit will be performed on day 60 postoperative.
