简要总结
RATIONALE: Drugs used in chemotherapy, such as fludarabine, work in different ways to stop cancer cells from dividing so they stop growing or die. Monoclonal antibodies, such as alemtuzumab and rituximab, can locate cancer cells and either kill them or deliver cancer-killing substances to them without harming normal cells. Combining chemotherapy with monoclonal antibody therapy may kill more cancer cells. It is not yet known whether fludarabine is more effective when combined with alemtuzumab or with rituximab in treating chronic lymphocytic leukemia.
PURPOSE: Randomized phase II trial to compare the effectiveness of combining fludarabine with either alemtuzumab or rituximab in treating patients who have refractory or relapsed B-cell chronic lymphocytic leukemia.
详细描述
OBJECTIVES:
Primary
- Compare the complete response rate in patients with refractory or relapsed B-cell chronic lymphocytic leukemia treated with fludarabine and alemtuzumab vs fludarabine and rituximab.
Secondary
- Compare the overall response rate in patients treated with these regimens.
- Compare 1-year survival of patients treated with these regimens.
- Compare time to progression in patients treated with these regimens.
- Compare duration of response in patients treated with these regimens.
- Compare the adverse event profile of these regimens in these patients.
- Compare the molecular response rate in patients treated with these regimens.
- Compare lymphocyte and lymphocyte subset recovery (CD3, CD3/CD4, CD3/CD8, CD20) in patients treated with these regimens.
- Compare the time to complete response in patients treated with these regimens.
- Compare the rate of cytomegalovirus reactivation and time to reactivation in patients treated with these regimens.
