Brief summary: The goal of this clinical research study is to learn if adding Zevalin (ibritumomab tiuxetan) to low-intensity chemotherapy (the combination of rituximab, bendamustine, and fludarabine), followed by an allogeneic stem cell transplant, can help to control lymphoma. The safety of this combination will also be studied.

Two (2) forms of ibritumomab tiuxetan will be used in this study. 90Y-ibritumomab tiuxetan is designed to attach to lymphoma cells and destroy the cells using a radioactive particle that is attached to it. 111In-ibritumomab tiuxetan is like 90Y- ibritumomab tiuxetan, but the radioactive particle that is attached to it does not kill lymphoma cells. The radioactive particle makes the drug able to be seen inside your body. It is being used in this study to predict how fast the study drug will travel in the body and how long the drug stays in the body.

Rituximab is designed to attach to lymphoma cells, which may cause them to die.

Bendamustine is designed to damage and destroy the DNA (genetic material) of cancer cells.

Fludarabine is designed to make cancer cells less able to repair damaged DNA. This may increase the likelihood of the cells dying.

Detailed description: Study Drug Administration and Procedures:

The chemotherapy, some of the other drugs in this study, and the stem cell transplant will be given by vein through your central venous catheter (CVC). A central venous catheter is a sterile flexible tube that will be placed into a large vein while you are under local anesthesia and will remain in your body during treatment. Your doctor will explain this procedure to you in more detail, and you will be required to sign a separate consent form. Blood samples will also be drawn through the CVC.

On Days -22 (22 days before you receive the stem cell transplant), you will receive rituximab by vein over 3-4 hours. You will then receive 111In-ibritumomab tiuxetan by vein over 30 minutes.

From Day -22 through Day -16, you will have scans called whole-body planar scintigraphy imaging. In these scans, a special camera will capture 2-dimensional images of the whole body to see where the radioactive 111In- ibritumomab tiuxetan that was injected on Day -22 has spread. No additional radiation will be used in this scan. Scintigraphy will be performed right after the injection, then 3-6 hours after the injection, then 24, 72, and 144 hours (+/- 2 hours) after the injection.

After the last scintigraphy imaging scan, the scans will be reviewed to learn how much radiation has traveled to different organs and to decide how much 90Y- ibritumomab should be used.

On Day-14, you will receive rituximab by vein over 3-4 hours. You will then receive the calculated dose of 90Y-ibritumomab tiuxetan by vein over 30 minutes.

On Days -5, -4, and -3, you will receive fludarabine and bendamustine by vein over 1 hour each day.

On Days -3 through Day 100, if your stem cells are from cord blood, you will receive mycophenolate mofetil (MMF) by vein or by mouth. MMF is designed to block the donor cells from growing and spreading in a way that could cause graft versus host disease (GVHD -- a condition in which transplanted tissue attacks the recipient's body).

Starting on Day -2, if your stem cells are from a related or matched unrelated donor, you will receive tacrolimus by vein as a continuous (nonstop) infusion until you are able to take it by mouth to help prevent GVHD. You will then take tacrolimus by mouth 2 times a day for about 3 months. After that, your tacrolimus dose may be lowered if you do not have GVHD. Your doctor will discuss this with you.

On Days -2 and -1, if your stems cells are from a matched unrelated donor or from cord blood, you will receive thymoglobulin (ATG) by vein over about 4 hours. ATG is designed to weaken your immune system to reduce the risk of rejecting of the transplant.

On Day 0, you will receive the blood stem cells by vein over about 30-45 minutes. Blood (less than 1 teaspoon) will also be drawn to measure how much (if any) radiation from the 90Y- ibritumomab tiuxetan is left in the blood.

Starting on Day 0, if your stem cells are from cord blood, you will receive filgrastim (G-CSF) through a needle under the skin 1 time a day every day until your white blood count begins to recover. G-CSF is designed to help cells in the bone marrow to divide, which helps raise white blood cells counts more quickly, lower fever, and decrease the risk of infection.

On Days 1, 3, and 6, if your stem cells are from a related or matched unrelated donor, you will receive methotrexate over 30 minutes each day by vein to help prevent GVHD. Patients receiving a matched unrelated donor will also be given methotrexate on Day 11 after the transplant.

Starting on Day 7, if your stem cells are from a related or matched unrelated donor, you will receive G-CSF through a needle under the skin 1 time a day every day until your white blood count begins to recover.

When your doctor thinks they are needed, you will also receive antibiotics and antifungal drugs to help prevent and/or treat infections. Your doctor will tell you more about how these drugs are given and possible side effects.

You will be in the hospital for about 3-4 weeks after you receive the stem cell transplant. During this time, the following tests and procedures will be performed at any point that your doctor thinks they are needed:

* You will have a physical exam, including measurement of your vital signs (blood pressure, heart rate, temperature, and breathing rate).
* You will be asked about how you are feeling and about any side effects you may be having.
* Blood (about 4-6 teaspoons) will be collected for routine tests, to check your kidney and liver function, and to learn if and how well the transplant is working.

The following may also be performed if at any point the doctor thinks they are needed:

* You may have imaging scans to check the status of the disease and/or to check for possible infections.
* You may have a bone marrow biopsy to check the status of the disease. To collect a bone marrow biopsy, an area of the hip or other site is numbed with anesthetic, and a small amount of bone marrow and bone is withdrawn through a needle.
* You may have transfusions of blood and/or platelets.

You must stay in the Houston area for about 100 days after the stem cell transplant.

Long-Term Follow-Up:

About 3, 6, and 12 months after the stem cell transplant:

* Blood (about 6 teaspoons) will be collected for routine tests, to check kidney and liver function, and to see how well the transplant has taken.
* You will have CT and PET scans to check the status of the disease.
* You will have a bone marrow biopsy/aspirate to check the status of the disease.

About 2 and 3 years after the stem cell transplant, you will receive a phone call that will take less than 10 minutes to learn how you are doing.

Length of Study:

You will be on study for up to about 3 years. You may be taken off study early if the disease gets worse, if you have any intolerable side effects, of if you are unable to follow study directions.

You should talk to the study doctor if you want to leave the study early. If you are taken off study early, you still may need to return for routine post-transplant follow-up visits, if your transplant doctor decides it is needed. It may be life-threatening to leave the study after you have begun to receive the study drugs but before you receive the stem cells.

This is an investigational study. Ibritumomab tiuxetan, rituximab, bendamustine, and fludarabine are FDA approved and commercially available for the treatment of lymphoma. The dose of ibritumomab tiuxetan in this study is designed to be higher than the FDA approved dose. The use of ibritumomab tiuxetan and bendamustine in combination with the other study drugs and a stem cell transplant for the treatment of lymphoma is investigational.

Up to 20 patients will take part in this study. All will be enrolled at MD Anderson.
