Every 1-4 weeks during the first 4 weeks of the study, you will have around 2 teaspoons of blood drawn for routine blood tests. The blood tests will then be repeated every 4-8 weeks (or more often if your doctor feels it is necessary) until you have been on study for 6 months, then every 3 to 6 months for another 18 months. After that, you may have the blood tests repeated as often as the doctor thinks it is needed. A bone marrow sample will also be taken every 3-4 months for the first year and then every 6-12 months in the 2nd year, then every 2-3 years for as long as you are on the study to check on the status of the disease. Additionally, blood (about ½ tablespoon) will be drawn or a bone marrow sample will be collected every 3-4 months for the first year and then every 6-12 months until 2 years, and then about one time a year for as long as you are on the study to check on the status of the disease. However, if you are in complete remission after Year 2, your doctor will decide when you will have a bone marrow aspiration. But you will still have blood drawn (about ½ tablespoon) every 1 - 3 years to check the status of your disease. An ECG will be repeated around Day 5, and then at about 6 weeks and about 3 months.
