Summary
The goal of this clinical research study is to learn if the combination of fludarabine, cyclophosphamide, alemtuzumab, and rituximab is effective in treating chronic lymphocytic leukemia in patients who have already been treated with chemotherapy.
Primary Objectives:
Evaluate the therapeutic efficacy, including the complete remission (CR), nodular partial remission (NPR), and partial remission (PR) rates (overall response) of combined cyclophosphamide, fludarabine, alemtuzumab, and rituximab (CFAR) in previously treated patients with Chronic Lymphocytic Leukemia (CLL).
Second Objectives:
* Assess the toxicity profile of CFAR in previously treated patients with CLL.
* Monitor for infection and determine incidence and etiology of infection including cytomegalovirus in patients treated with CFAR.
* Evaluate molecular remission by polymerase chain reaction (PCR) for the clonal immunoglobulin heavy chain variable gene in responding patients treated with CFAR.
* Assess immune parameters, including pretreatment, during treatment, and post-treatment blood T-cell counts and subset distribution and serum immunoglobulin levels in patients treated with CFAR.
Eligibility Criteria
Inclusion Criteria
- All patients must have been diagnosed with CLL by immunophenotyping and flow cytometry analysis of blood or bone marrow demonstrating a monoclonal population of CD5 and CD19 positive cells.
- All patient must have been previously treated with chemotherapy.
- All patients with Rai stage III-IV are eligible for treatment with this protocol. - OR - All patients with Rai stage 0-II who meet one or more indication for treatment as defined by the NCI-sponsored Working Group are eligible for treatment with this protocol.
- All patients must have a Zubrod performance status of 0-3.
- All patients must have adequate renal and hepatic function (serum creatinine <2mg/dL; total bilirubin <2.5mg/dL). Patients with renal or liver dysfunction due to organ infiltration by lymphocytes may be eligible after discussion with the Principle Investigator and appropriate dose adjustment considered.
- Patients may not receive concurrent chemotherapy, radiotherapy, or immunotherapy. Localized radiotherapy to an area not compromising bone marrow function does not apply, nor do hematopoietic growth factors such as erythropoietin, Granulocyte colony-stimulating factor (G-CSF or GCSF, GM-CSF etc).
- Patients must not have untreated or uncontrolled life-threatening infection.
- Patients must sign informed consent.
Exclusion Criteria
- None
