If you come off this study because you completed therapy, your disease got worse, or you experienced intolerable side effects, you will have an end-of-study visit. During this visit, you will have blood drawn (about 3 tablespoons) for routine tests. You will have a complete physical exam, including measurement of your vital signs. You will also have your complete medical history recorded and you will be asked about any medications you are currently taking. You will have imaging scans to evaluate your disease (similar to those at screening) if they have not been done in the last 28 days.
