During treatment, you will have a physical exam and routine blood (about 2 teaspoons) and urine tests. You will also have an ECG, a chest x-ray, and other scans as thought necessary. The physical exam will be done once a week for Courses 1 - 3. The blood tests will be done on Days 1, 3, 5; then twice weekly and on Day 22 of each course. Urine tests will be done on Day 1 of each course and at the end of Course 2. The scans and ECG will be performed at the end of each course or sooner if it is suspected that the disease has gotten worse.
