Venous Thromboembolism (VTE) Treatment Study in Japanese Deep Vein Thrombosis (DVT) Patients - Full Text View

Purpose

The objective of this study is to evaluate the efficacy, safety, pharmacokinetics (PK) and pharmacodynamics (PD) of two different dosages of rivaroxaban in the treatment of deep vein thrombosis (DVT) and the prevention of the occurrence and the recurrence of DVT or pulmonary embolism (PE) in Japanese patients with acute symptomatic DVT without symptomatic PE.

Primary Outcome Measures:

Number of participants with newly onset of symptomatic venous thromboembolism (VTE) [ Time Frame: Up to 12 months ]
Number of clinically relevant bleedings [ Time Frame: Up to 2 days after last dose ]

Secondary Outcome Measures:

Number of participants with improvement in thrombotic burden [ Time Frame: At week 3 ]
Number of participants with deterioration in thrombotic burden [ Time Frame: Up to 12 months ]
Number of participants with the composite of newly onset of symptomatic VTE or asymptomatic deterioration of thrombus [ Time Frame: Up to 12 months ]


Enrollment:	60
Study Start Date:	March 2012
Study Completion Date:	January 2014
Primary Completion Date:	December 2013 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Experimental: Arm 1	Drug: Rivaroxaban (Xarelto, BAY59-7939) 10 mg twice daily for 21 days, followed by 15 mg once daily
Experimental: Arm 2	Drug: Rivaroxaban (Xarelto, BAY59-7939) 15 mg twice daily for 21 days, followed by 15 mg once daily
Active Comparator: Arm 3	Drug: Unfractionated heparin To be adjusted to maintain the activated partial thromboplastin time (aPTT) prolongation (1.5 to 2.5 times the control)
Active Comparator: Arm 4	Drug: Warfarin To be adjusted on the basis of prothrombin time-international normalized ratio (PT-INR) values target range (1.5 to 2.5)

Detailed Description:

The general design of the trial is open label between the Rivaroxaban and the reference arm. However, there are two groups in the Rivaroxaban arm only for the initial 3 weeks. Between these two groups and in this initial period, the study is blinded.

Eligibility


Ages Eligible for Study:	20 Years and older (Adult, Senior)
Sexes Eligible for Study:	All
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Men and women >/= 20 years of age in patients with confirmed acute symptomatic proximal deep vein thrombosis (DVT) without symptomatic pulmonary embolism (PE)

Exclusion Criteria:

Thrombectomy, insertion of a caval filter, or use of a fibrinolytic agent to treat the current episode of DVT
More than 48 hours pre-randomization treatment with therapeutic dosages of anti-coagulant treatment or more than a single dose of warfarin from the onset of the current episode of DVT to randomization
Calculated creatinine clearance (CLCR) < 30 mL/min
Subjects with hepatic disease which is associated with coagulopathy leading to a clinically relevant bleeding risk
Active bleeding or high risk for bleeding contraindicating treatment with unfractioned Heparin (UFH) or warfarin
Systolic blood pressure > 180 mmHg or diastolic blood pressure > 110 mmHg
