Gemcitabine Plus Busulfan, Melphalan and Hematopoietic Cell Transplant for Advanced Lymphoid Malignancies

Gemcitabine Plus Busulfan, Melphalan and Hematopoietic Cell Transplant for Advanced Lymphoid Malignancies

Gemcitabine Combined With Busulfan and Melphalan, With Hematopoietic Cell Transplantation, for Patients With Poor-prognosis Advanced Lymphoid Malignancies

The goal of this clinical research study is to find the highest tolerated dose of gemcitabine that can be given with busulfan and melphalan. The safety of this drug combination will also be studied.

Busulfan and melphalan are designed to kill cancer cells by binding to DNA (the genetic material of cells), which may cause cancer cells to die. They are commonly used in stem cell transplantation. Gemcitabine is designed to disrupt the growth of cancer cells, which may cause cancer cells to die. It may help to increase the effect of busulfan and melphalan on the tumor cells, by not allowing these cells to repair the DNA damage caused by busulfan or melphalan. You will have apheresis done to collect some of your stem cells. Apheresis is the process of removing part of the blood (such as platelets or white blood cells) from the body in order to remove certain elements, such as stem cells. Then, the rest of the blood is returned back to your body. Your stem cells will be put back in your body after you finish receiving gemcitabine, busulfan, and melphalan. Apheresis will be done by a major vein through a central venous catheter (CVC), usually in the chest. A CVC is a sterile flexible tube that will be placed into a large vein while you are under local anesthesia. Your doctor will explain these procedures to you in more detail, and you will be required to sign a separate consent form for each procedure. If you are found to be eligible to take part in this study, you will be enrolled in a group of at least 2 participants to begin receiving the study drugs. The dose of the study drugs you receive will depend on when you enrolled in this study. If no intolerable side effects occur in your group, researchers will continue to enroll participants at the next highest dose level until the highest tolerable dose of the study drugs is found. The dose that you receive will remain the same throughout this study. Before you start to receive chemotherapy at treatment doses, you will be given a very small test dose of busulfan. Blood (1 teaspoon) will be drawn to check the levels of the drug in your blood at ten different timepoints (5-6 tablespoons total). This will help the study staff calculate your treatment doses of this drug. If there is a schedule conflict and the laboratory is not available for this testing, this procedure will not be performed. In that case, you would receive an unchanging dose of busulfan during the treatment. During Day 1 you will receive gemcitabine and busulfan by CVC. On Days 2-4, you will receive busulfan. On Day 5, you will not receive any study drugs. On Day 6, you will receive gemcitabine followed by melphalan. On Day 7, you will receive melphalan. On Day 8, you will not receive any study drugs. On Day 9, you will receive your autologous stem cells through a needle in your vein over about 30-60 minutes. If you have a B-cell cancer, you will receive rituximab (a treatment used for certain lymphomas or chronic lymphocytic leukemia) as part of standard of care, 1 day after and again 8 days after the infusion of the autologous cells. As part of standard care, you will receive G-CSF (filgrastim) as an injection just under your skin daily, starting 1 day after the transplant, until your blood cell levels return to normal. As part of standard care, you will receive a total of 6 doses of palifermin by vein. Three (3) of the doses will be given before starting chemotherapy (with a 24-hour break between the last dose of palifermin and the first dose of chemotherapy), and 3 doses will be given after the last chemotherapy dose, starting on Day 0. You will be taken off this study 100 days after the transplant. You may be taken off this study early if the disease gets worse or you experience any intolerable side effects. As part of standard care, you will remain in the hospital for about 3-4 weeks after transplantation. After you are released from the hospital, you will continue as an outpatient in the Houston area to be monitored for infections and transplant-related complications. This is an investigational study. Busulfan, gemcitabine, and melphalan are all FDA approved and commercially available. The use of these study drugs together and the use of gemcitabine at these dose levels is investigational. Up to 143 patients will take part in this study. All will be enrolled at M. D. Anderson.
