 We will continue to follow the subject in the BMT clinic after the injections. To learn more about the way the T cells are working, an extra 40 mls about 8 teaspoonfuls of blood will be taken pre-infusion, 4 hours after the infusion, 3-4 days post infusion optional and at 1, 2, 4 and 6 weeks after the T cell infusions, and then at 3, 6, 9, and 12 months post infusion. The blood should come from the central intravenous line, and should not require extra needle sticks.
