Treatment of Splanchnic Vein Thrombosis With Rivaroxaban. A Pilot, Prospective Cohort Study

Portal Vein Thrombosis Clinical Trial

Official title:
Treatment of Portal, Mesenteric, and Splenic Vein Thrombosis With Rivaroxaban. A Pilot, Prospective Cohort Study

Clinical Trial Summary

Anticoagulant therapy is generally recommended for all patients presenting with acute symptomatic splanchnic vein thrombosis, starting with either low-molecular weight heparin (LMWH) or unfractionated heparin and continuing with the vitamin K antagonists in most patients. Rivaroxaban is approved for the treatment of deep vein thrombosis and pulmonary embolism, but no studies have assessed the safety of rivaroxaban in the setting of splanchnic vein thrombosis. The investigators aim to collect prospective information on the safety of rivaroxaban in a pilot cohort of 100 patients with acute splanchnic vein thrombosis without liver cirrhosis.

Clinical Trial Description

Patients with splanchnic vein thrombosis are at increased risk of recurrent VTE and bleeding. Routine anticoagulation with unfractionated heparin or low molecular weight heparin followed by warfarin is recommended in this setting, but limited data is available to support this recommendation and more than 20% of these patients do not receive antithrombotic treatment due the fear for bleeding complications. The pharmacokinetic and pharmacodynamic characteristics of rivaroxaban make this drug an ideal alternative therapeutic strategy for the treatment of patients with SVT. Thanks to the oral route of administration, the short half-life, the high bioavailability, the predictable dose-response and the lack of effects on platelet activity, rivaroxaban could result as an important alternative to both LMWH and warfarin in the acute and long-term treatment of SVT patients. Furthermore, the analysis of phase III studies conducted in patients with DVT or PE have shown a better safety profile of rivaroxaban as compared to standard of treatment. This observed benefit in the safety profile of rivaroxaban would be extremely relevant in the treatment of patients with SVT. In this prospective cohort study, patients presenting with acute SVT will receive rivaroxaban 15 mg bid for 3 weeks followed by rivaroxaban 20 mg od for a total of 3 months. The primary safety and efficacy outcomes will be measured at 3 months. ;
