Before you can start treatment on the 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. At the screening visit, you will be asked questions about your medical history and any medications you use. You will be asked questions about your ability to carry out everyday activities (performance status). You will have a complete physical exam, including measurement of your vital signs (blood pressure, pulse, breathing rate, and temperature), routine blood (about 1 teaspoon) and urine tests, and an electrocardiogram (ECG--a test to measure the electrical activity of the heart).
