Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
First patient first visit date: 04 DEC 2007; last patient last visit date 24 NOV 2010. Primary completion date: 12 AUG 2010. Participants were aged ≥40 years, hospitalized for an acute medical illness, and at risk of Venous Thromboembolism (VTE) (with heart failure, cancer, ischemic stroke, infection or inflammation, or respiratory insufficiency)

Pre-Assignment Details
Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 8428 participants were screened; 327 failed. 8101 were randomized. 7998 (98.7%) were in the Safety Analysis Set (SAF), i.e. received study medication. 6024 (74.4%) were in the modified Intent to Treat (at Day 35) group (valid for SAF with adequate assessment of venous thromboembolism). A total of 6005 (74.1%) completed study.

Reporting Groups

Enoxaparin Participants received oral rivaroxaban-matched placebo tablet OD for 35 +/- 4 days, plus 40 mg subcutaneous enoxaparin solution OD for 10 +/- 4 days during treatment period

  Limitations and Caveats
  Hide Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
A heterogeneous population (with different acute medical illnesses and severity of illness) was included in the trial. VTE risk in acute medical illnesses is moderate [with no thromboprophylaxis] .
