Immunotherapy With NK Cell, Rituximab and Rhu-GMCSF in Non-Myeloablative Allogeneic Stem Cell Transplantation

This study is ongoing, but not recruiting participants.

The goal of this clinical research study is to find out if giving a boost of natural killer (NK) cells from a donor combined with Rituxan (rituximab), can help to control disease in patients who have already received an allogeneic stem cell transplant. The safety of this treatment will also be studied. Participants have recurrent chronic lymphocytic leukemia (CLL) or lymphoma after non-myeloablative stem cell transplantation.

Primary Objectives:

1.0 To determine the safety of Natural Killer (NK) cells and Rituximab + rhu-Granulocyte-macrophage colony-stimulating factor (GMCSF) in patients with persistent or recurrent B-cell lymphoid malignancies after non-myeloablative stem cell transplantation.

2.0 To determine factors associated with response.

Primary Outcome Measures:
  • Dose-limiting toxicities (DLTs) for NK cells infusions after non-myeloablative transplantation for lymphoid malignancies [ Time Frame: Evaluated for toxicity within 6 weeks of treatment ]
    Maximum tolerated dose (MTD) is the highest dose with 10 patients treated and 5 or fewer patients with DLT.

Arms Assigned Interventions
Experimental: Immunotherapy with NK Cell, Rituximab + GM-CSF

Immunotherapy in Non-myeloablative Allogeneic Stem Cell Transplantation

GM-CSF = Granulocyte-Macrophage Colony-Stimulating Factor

Drug: GM-CSF
250 micrograms subcutaneously 3 times a week for 4 weeks starting a day before the administration of Rituximab.
Other Names:
  • Sargramostim
  • Leukine
Drug: Rituximab
375 mg/m^2 by vein followed by 1000 mg/m^2 weekly for 3 weeks for a total of 4 doses.
Other Name: Rituxan
Biological: NK Cell Infusion
NK cells will be infused one week after the fourth dose of Rituximab and GM-CSF.

Detailed Description:

Rituximab is designed to attach to lymphoma cells, causing them to die. GM-CSF and NK cells may increase rituximab's ability to kill these cells.

Before you can start treatment on this study, you will have what are called "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have your complete medical history recorded and a physical exam. Your blood (about 2 tablespoons) will be collected for routine tests. A bone marrow aspirate will be performed. To collect a bone marrow aspirate, an area of the hip or chest bone is numbed with anesthetic and a small amount of bone marrow is withdrawn through a large needle. You will have computerized tomography (CT) scans as well as positron emission tomography (PET) or gallium scans to learn the status of your disease. Women who are able to have children must have a negative blood or urine pregnancy test.

If you are found eligible to take part in this study, you will receive treatment as an outpatient. You will receive GM-CSF 3 times a week for 4 weeks through a vein, starting the day before you receive the administration of rituximab. You will receive rituximab over 4 to 8 hours through a vein, once weekly for 4 weeks. You will also get a boost of NK cells from the same donor from whom you received your original transplant. These cells will be infused through a vein (over 30 to 60 minutes) after the 4th dose of rituximab. If you are receiving a cell infusion from somebody who you are not related to, the infusion may have to be done later if cells were not available as scheduled.

The CliniMACS System is a medical device that is used to separate types of blood cells from blood that is removed from the body during leukapheresis. These separated cells are processed for use in treatments such as stem cell transplants.

During this treatment, you will be examined as needed, and blood samples (1 tablespoon once or twice a week) will be taken for routine tests. You may need to receive blood transfusions during this study if your blood cell counts remain low.

You may be taken off this study if your disease gets worse or intolerable side effects occur.

You will have long-term, follow-up visits while on study. You will be seen at 4 to 6 weeks after you receive NK cell infusion; every 3 months during the first year; and then once a year. During each of these visits, you will have CT and PET scans, a bone marrow biopsy, and blood drawn (about 4 teaspoons) to learn the status of your disease.

This is an investigational study. Rituximab and GM-CSF are FDA approved and commercially available. NK cells are authorized by the FDA for use in research only. Up to 40 participants will take part in this study. All will be enrolled at the University of Texas (UT) MD Anderson Cancer Center.
