Before you can receive the drug on this study, you will have what are called "screening tests." These tests will help the doctor decide if you are eligible to take part in the study. Your complete medical history will be recorded and you will have a physical exam. You will have an electrocardiogram (ECG -- a test that measures the electrical activity of the heart). You may also have x-rays, computed tomography (CT) scans, or magnetic resonance imaging, whichever imagining your doctor thinks is best to monitor the status of the disease.
