Before you can start taking the drugs 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. These tests may be performed within 28 days of starting the study drugs. If you have had some of these exams, tests, or procedures performed recently, they may not need to be repeated. This will be for your study doctor to decide. 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 x-rays and a bone marrow biopsy to check the status of the disease. To collect a bone marrow biopsy, an area of the hip or chest bone is numbed with anesthetic, and a small amount of bone marrow and bone is withdrawn through a large needle. You will have a computed tomography (CT) scan of your abdomen, chest, and pelvis and a positron emission tomography (PET) scan. Blood (about 2-3 tablespoons) will be drawn for routine tests. Women who are able to have children must have a negative blood (about 1 teaspoon) pregnancy test within 1 month before starting therapy on this study. Because taking part in this study requires that participants' ability to fight off infections be normal, you will have blood drawn (about 1-2 tablespoons) to be tested for HIV within 6 months before starting therapy on this study. If your HIV test results are found to be positive, you will not be able to take part in this study.
