Phase II Investigation of 99mTc-rBitistatin for Imaging Venous Thrombosis

May 1, 2015 updated by: Temple University
99mTc-rBitistatin is a radiolabeled polypeptide which is designed to stick to blood clots so that the blood clots can be detected by imaging. The purpose of this trial is to evaluate in patients the safety of 99mTc-rBitistatin and its ability to locate blood clots in the arms and legs.
