Comparison of Arixtra vs. Lovenox to Prevent Blood Clots in Medically Ill Patients (BRiEF)

This study has been terminated.

Lehigh Valley Hospital Identifier:
First received: August 24, 2007
Last updated: September 18, 2014
Last verified: September 2014
A total of 50 patients >40 yrs of age with an expected hospital stay in the Medical Intensive Care or Regional Heart Unit at LVH Muhlenberg of 6 days or longer will be enrolled. The patient and study team will be blinded to which drug they are receiving (either Arixtra or Lovenox). Subjects will be examined for any bleeding complications. Subjects will receive drug for a total of 6-14 days while in the hospital. A follow up phone call will be performed by the study team approximately 30 days after discharge from the hospital.
