Protocol Number: 06-H-0190
Patients 18 to 85 years of age with T-LGL leukemia may be eligible for this study. Participants undergo the following procedures: Before starting Campath® (Registered Trademark) treatment -Medical history and physical examination, blood tests, electrocardiogram (ECG). -Echocardiogram (heart ultrasound) and 24-hour Holter monitoring (continuous ECG recording). -Bone marrow biopsy: About a tablespoon of bone marrow is withdrawn through a needle inserted into the hipbone. The procedure is done using local anesthetic. -Placement of central line, if needed: An intravenous line (tube) is placed into a major vein in the chest. It can stay in the body and be used for the entire treatment period. The line is used to give chemotherapy or other medications, including antibiotics and blood transfusions, and to collect blood samples. The line is usually placed under local anesthesia in the radiology department or the operating room. -Apheresis: A catheter (plastic tube) is placed in a vein in each arm. Blood is drawn from one vein and run through a cell-separating machine, where the white blood cells are collected and saved. The remaining blood is transfused back to the patients through the vein in the other arm. During Campath® (Registered Trademark) treatment -Campath® (Registered Trademark) therapy: After a small test dose, patients receive10 daily infusions of Campath® (Registered Trademark), each of which lasts about 2 hours. The first few infusions are given at the NIH Clinical Center so that the patient can be monitored closely. -Induction therapy: Aerosolized pentamadine, valacyclovir and other medicines are given to protect against or treat various infections that commonly affect patients with suppressed immune systems. -Whole blood or platelet transfusions, if needed, and injections of growth factors, if needed. -Blood tests and check of vital signs (temperature, pulse, blood pressure) every day during treatment. Echocardiogram and 24-hour Holter monitor after the last dose of Campath® (Registered Trademark). Follow-up evaluations after Campath® (Registered Trademark) treatment ends -Blood tests at home or at NIH (weekly for the first 3 months, then every other week until 6 months, then annually for 5 years -Echocardiogram at NIH (at 3 months only) -Bone marrow biopsy at NIH (at 6 and 12 months, then as clinically indicated) -One repeat apheresis collection for laboratory studies.
