Trial Purpose

This is an observational study in which data from the past is collected for a treatment which is already available for doctors to prescribe for venous thromboembolism (VTE). VTE is a condition in which blood clots form in veins, which can lead to disability and death. This study looks at the bleeding risk in Japanese patients who are already receiving long-term rivaroxaban treatment for their VTE.

Some common causes of VTE are surgery, lack of movement, being bed-ridden and cancer. VTE that is caused by cancer is called cancer-associated venous thromboembolism (Ca-VTE).

The study treatment, rivaroxaban, is a blood thinner prescribed by doctors to help treat conditions like VTE. By thinning the blood, rivaroxaban can help keep blood flowing normally and prevent blood clots. But, rivaroxaban can lead to increased bleeding in some people.

There have been studies done in which participants with VTE and Ca-VTE received treatment with rivaroxaban for a long period of time. The overall results of those studies showed that long-term treatment with rivaroxaban helped prevent blood clots in those participants. Some of the participants had increased bleeding after this long-term treatment, while some did not. Participants with certain types of cancers, such as Ca-VTE, also had an increased risk of bleeding.

These studies, however, did not include Japanese participants. So, the researchers in this study want to learn more about the risk of bleeding in Japanese patients with VTE or Ca-VTE who receive long-term treatment with rivaroxaban. To do this, the researchers plan to use a medical database to find information for patients with VTE and Ca-VTE who have already been taking rivaroxaban for their condition. This database will help the researchers collect information about the bleeding risk of long-term rivaroxaban treatment in Japanese patients.

In this study, the researchers will learn more about:
• the characteristics of patients with VTE who are treated with rivaroxaban for a period of less than 3 months to more than 1 year
• the bleeding risk for all of the patients throughout the study
• the bleeding risk for the patients with Ca-VTE throughout the study
• the cause of any bleeding that happens

The researchers will follow and record these results for Japanese patients from October 2015 to December 2020.
