Donor Lymphocyte Infusion (DLI) of T-cells Genetically Modified With iCasp9 Suicide Gene

Study Overview
=================
Brief Summary
-----------------
The goal of this clinical research study is to learn if giving genetically changed immune cells, called T-cells, after chemotherapy will improve the response to a stem cell transplant. The safety of this treatment will also be studied. The process of changing the DNA (the genetic material in cells) of these T-cells is called gene transfer. Researchers want to learn if these genetically-changed T-cells are effective in attacking cancer cells in patients with leukemia, MDS, lymphoma, Hodgkin disease, or MM, after they have received an allogeneic stem cell transplant. The chemotherapy you will be given on study is fludarabine, melphalan, and alemtuzumab. These drugs are designed to stop the growth of cancer cells, which may cause the cancer cells to die. This chemotherapy is also designed to block your body's ability to reject the donor's stem cells. Researchers also want to learn if giving AP1903 will help the symptoms of graft-versus-host disease (GvHD) that may occur after the T-cell infusion. GvHD occurs when donor cells attack the cells of the person receiving the stem cell transplant.

Detailed Description
-----------------
Gene Transfer: Gene transfer involves drawing blood from a transplant donor, and then separating out the T-cells using a machine. Researchers then perform a gene transfer to change the T-cells' DNA, and then inject the changed T-cells into the body of the patient receiving the transplant. Study Drug Administration: You will receive fludarabine, melphalan, and alemtuzumab to kill cancer cells and help prevent your body from rejecting the stem cells. The day you receive the stem cells is called Day 0. The days before you receive your stem cells are called minus days. The days after you receive the stem cells are called plus days. On Day -7, you will be admitted to the hospital and given fluids by vein to hydrate you. On Days -6 through -3, you will receive fludarabine by vein over 1 hour each day. On Day -2, you will receive melphalan by vein over 30 minutes. On Day -1, you will receive alemtuzumab by vein over 2 hours. On Day 0, you will receive the stem cell transplant as a cell infusion by vein. After the transplant, you will receive tacrolimus and methotrexate. At first, you will receive tacrolimus as a continuous (nonstop) infusion until you are able to take it by mouth. You will then take tacrolimus by mouth 2 times a day for about 3 weeks and then your doctor will tell you how to taper it off (gradually stop taking it). On Days +1, +3, +6, and +11, you will receive methotrexate by vein over 30 minutes. You will receive filgrastim as an injection under the skin 1 time a day, starting 1 week after the transplant, until your blood cell levels return to normal. Filgrastim is designed to help with the growth of white blood cells. Between Day +56 and +64, if you are in stable medical condition and have not developed GvHD, you will receive a donor lymphocyte infusion containing genetically modified T-cells by vein over 10-30 minutes. You will receive Benadryl (diphenhydramine) by vein over 15 minutes and Tylenol by mouth before the infusion to lower the risk of an allergic reaction. If your doctor thinks it is needed due to medical problems, the T-cell infusion may be postponed for up to 6 months after the transplant. If you develop symptoms of GvHD after the T-cell infusion, you must return to the clinic within 72 hours. Most cases of GVHD occur within 60 days of the T-cell infusion. If you have GvHD, you will receive AP1903 by vein and possibly steroids by mouth or by vein. If your doctor thinks it is needed, you may receive one more dose of AP1903 by vein 24-72 hours after the first dose. If GvHD returns after the first treatment and your doctor thinks it is needed, you may receive AP1903 by vein and steroids by mouth or by vein. Blood (about 2 tablespoons each time) will be drawn about 3 hours before you receive AP1903, about 2 hours after the AP1903 infusion, and then about 24 hours after the AP1903 infusion to check the level of genetically modified T-cells. You will then come to the clinic every day for the next 3 days and for an additional 3 days after a second dose of AP1903, if given. In addition, you will come to the clinic on about Days +7, +14, +28, +42 and +56 after receiving AP1903. If your symptoms do not improve after receiving AP1903, you will be given standard drugs for GvHD. Study Tests: After the stem cell transplant but before the T-cell infusion, you will have the following tests and procedures to find out if you will be eligible for the T-cell infusion: You will have a physical exam. You will be checked for possible reactions to treatment, including GvHD. Blood (about 4 tablespoons) will be drawn for routine tests, to check your liver and kidney function, for chimerism studies (determination of donor or recipient cells), and to check for cytomegalovirus (CMV). If your doctor thinks it is needed, you will have a bone marrow aspiration and biopsy performed to check the status of the disease. To collect a bone marrow aspiration/biopsy, an area of the hip is numbed with anesthetic, and a small amount of bone marrow and bone is withdrawn through a large needle. About twice a week until about 2 months after the T-cell infusion, and then 6 and 12 months after the stem cell transplant: You will have a physical exam, including measurement of your height, weight and vital signs. Your medical history will be recorded. You will have be checked for possible reactions to your treatment, including GvHD. Blood (about 4 tablespoons) will be drawn for routine tests, to check your liver and kidney function, and to check for CMV and other infections. Part of the blood may be used for chimerism studies, if your doctor thinks it is needed. If your doctor thinks it is needed, you may have a bone marrow aspiration and biopsy performed to check the status of the disease and for chimerism studies. If your doctor thinks it is needed, some tests and procedures may be repeated more frequently or at different time points during the study. Immune System and T-cell Level Tests: If possible, blood (about 3 tablespoons) will be drawn to check the status of the disease and your immune system function: 4 hours after the T-cell infusion, once a week for 1 month after the T-cell infusion, and then at 6 weeks and then about 2, 3, 6, 9, and 12 months after the T-cell infusion. °Part of the blood sample will be used to check for HAMA at 3 months after the T-cell infusion. Part of the blood drawn will be tested to check the level and function of the infused T-cells. At 3 months after the T-cell infusion, blood (about 1 teaspoon) will be drawn to check for HAMA. Questionnaires: You will complete a quality of life questionnaire that will take about 5-10 minutes each time: When you enroll on this study At the time of the T-cell infusion If you develop symptoms of GvHD after the T-cell infusion and receive AP1903, you will complete the questionnaire before you receive AP1903, and then about 7 and 14 days after you receive AP1903. If you do not develop symptoms of GvHD, you will complete a questionnaire about 1 month after the T-cell infusion. Length of Treatment: You will be off study after your 1-year follow-up visit. You will be taken off study early if: not enough donor cells could be collected you were not eligible to receive the T-cell infusion you have graft failure (the donor cells did not take) the disease comes back and needs another treatment you are unable to keep appointments you did not return to the clinic within 72 hours of having symptoms of GvHD your study doctor thinks it is in your best interest If you are taken off study, you will receive standard of care treatment. Long-Term Follow-Up: For safety reasons, the U.S. Food and Drug Administration (FDA) requires that patients who receive infusions of stem cells treated with a gene transfer procedure must have long-term follow-up yearly for at least 15 years after receiving the gene transfer. You will have blood tests performed to check to make sure you do not have a type of infection called the replication-competent retrovirus (RCR). For this test, blood (up to 4 teaspoons each time) will drawn about 1, 3, and 6 months after the T-cell infusion, then once every 6 months for 5 years, and then once a year after that for 10 years. If the RCR test results during the first year after the T-cell infusion show that you do not have the RCR infection, the rest of your leftover blood samples (left over from RCR testing in Years 2-15) will be stored at Bellicum for safety reasons. This is so researchers can study any changes in your blood (related to RCR) that may arise in Years 2-15. You will be asked to sign a separate consent form for a long-term follow-up study, Protocol 2006-0676. If for any reason you are unable to receive the genetically modified cells, you will not be enrolled on the long-term follow-up study. This is an investigational study. The gene transfer or infusion with genetically-changed T-cells and the drug, AP1903, are not FDA approved or commercially available for use in this type of disease. They are currently being used for research purposes only. Fludarabine, melphalan, and alemtuzumab are commercially available and FDA approved. Up to 35 patients will take part in this study. All will be enrolled at MD Anderson.
