Trial ID: NCT00767234
Purpose
To determine whether biomarkers assessed in blood samples can be used to detect individuals
at risk for developing blood clots or worsening of their underlying disease. The ultimate
goal of the study is to identify key biomarkers derived from blood that are most
characteristic and informative of individuals who will go on to develop a clotting
complication.
