Identifying Prognostic Factors in Frontline FCR for Patients With Chronic Lymphocytic Leukemia (CLL)

Clinical Trial Summary

The goal of this clinical research study is to learn more about the characteristics of CLL, including genes and chromosome abnormalities and proteins expressed by the leukemia cells, which may help doctors predict if patients who receive standard treatment (fludarabine, cyclophosphamide, and rituximab) for the first time will experience a complete remission.

The Study Drugs: Fludarabine is designed to make cancer cells less able to repair damaged DNA (the genetic material of cells). This may increase the likelihood of the cells dying. Cyclophosphamide is designed to interfere with the multiplication of cancer cells, which may slow or stop their growth and spread throughout the body. This may cause the cancer cells to die. Rituximab is designed to attach to lymphoma cells, which may cause them to die. Study Drug Administration: Each cycle is 4-6 weeks. If you are found to be eligible to take part in this study, on Day 1 of each cycle, you will receive rituximab through a needle into your vein over 6-8 hours. On Days 2-4 of Cycle 1 and Days 1-3 of Cycles 2 and beyond, you will receive fludarabine by vein over 30 minutes. You will also receive cyclophosphamide by vein over 30 minutes. You will receive drugs (such as Tylenol, Benadryl, Zofran, allopurinol, and Valtrex) to help prevent side effects. If you have side effects while receiving rituximab, you may be monitored by the study staff for 2 hours after each dose. Study Visits: Once a week, blood (about 1 tablespoon) will be drawn for routine tests. After 3 months (3 cycles of treatment), the following tests and procedures will be performed: - You will have a physical exam. - Blood (about 2 tablespoons) will be drawn for routine tests. - You will have a bone marrow aspirate and biopsy to check the status of the disease. Length of Study: You will be on treatment for about 6 months. You will be taken off treatment early if you have intolerable side effects or the disease gets worse. End-of-Treatment Visit: After you are off treatment, you will have an end-of-treatment visit for doctors to learn your overall response to the treatment. The following tests and procedures will be performed: - You will have a physical exam. - Blood (about 2 tablespoons) will be drawn for routine tests. - You will have a bone marrow aspirate and biopsy to check the status of the disease. Long-Term Follow-up: At 6 months after you have finished treatment and then every year from then on, you will have follow-up visits. The following tests and procedures will be performed: - You will have a physical exam. - Blood (about 2 tablespoons) will be drawn for routine tests. - If your doctor thinks it is needed, you will have a bone marrow biopsy and aspirate to check the status of the disease. This is an investigational study. Fludarabine, cyclophosphamide, and rituximab are FDA approved and commercially available for the treatment of CLL. The correlation with response to treatment and the characteristics of the leukemia cells is investigational. Up to 300 patients will take part in this study. All will be enrolled at MD Anderson. ;
