One month after your last treatment cycle, you will return to the clinic for a follow-up evaluation. You will be asked questions about your ability to carry out everyday activities (performance status). You will be asked questions about your medical history and the medications you used since the last visit. You will have a physical exam, including measurement of your vital signs, routine blood (about 1 teaspoon) and urine tests, and an ECG. You will have a neurological exam. You will be asked questions about your physical, social/family, emotional, and functional well-being, as well as additional concerns you may have regarding numbness, tingling, discomforts, and difficulties you may be having. A single blood collection (less than half of a teaspoon) will be taken for PK testing. Women who are able to have children will have a blood pregnancy test.
