Trial Summary

What is the purpose of this trial?

RATIONALE: Monoclonal antibodies, such as rituximab and alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer killing substances to them. Giving rituximab together with alemtuzumab may kill more cancer cells. PURPOSE: This randomized phase II trial is studying two different doses of rituximab to compare how well they work when given together with alemtuzumab in treating older patients with progressive chronic lymphocytic leukemia.

Active Control

Group I: Arm B (low dose)Experimental Treatment2 Interventions

Patients receive alemtuzumab SC on days 1-3, 6, 8, 10, 13, 15, 17, 20, 22, 24, 27, 29, and 31 and low-dose rituximab at 20 mg/m\^2 IV on days 6, 8, 10, 13, 15, 17, 20, 22, 24, 27, 29, and 31 in cycle 1 (33-day cycle). In cycle 2 and subsequent cycles (28-day cycle), patients receive alemtuzumab SC and low-dose rituximab IV on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26. Treatment repeats every 28 days for up to 3 cycles. Alemtuzumab dose for cycle 1 week 1 requires a 'dose ramp' (3 mg day 1, 10 mg day2, and 30 mg day 3 of cycle 1) and then is 30 mg 3 times a week.

Group II: Arm A (standard dose)Active Control2 Interventions

Patients receive alemtuzumab subcutaneously (SC) on days 1-3, 6, 8, 10, 13, 15, 17, 20, 22, 24, 27, 29, and 31 and standard-dose rituximab 375 mg/m\^2/week intravenously (IV) on days 8, 15, 22, and 29 in cycle 1 (33-day cycle). In cycle 2 and subsequent cycles (28-day cycle), patients receive alemtuzumab SC on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, and 26 and standard-dose rituximab IV on days 3, 10, 17, and 24. Treatment repeats every 28 days for up to 3 cycles. Alemtuzumab dose for cycle 1 week 1 requires a 'dose ramp' (3 mg day 1, 10 mg day2, and 30 mg day 3 of cycle 1) and then is 30 mg 3 times a week.
