Before you can start treatment on this study, you will have "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. Your complete medical history will be recorded, and you will have a physical exam, including measurement of your vital signs (blood pressure, heart rate, temperature, and breathing rate), height, and weight. You will have blood drawn (about 2 tablespoons) for routine tests. Women who are able to have children must have a negative blood (a sample will be used from the routine blood draw) or urine pregnancy test.
