Summary
Brief summary (as posted)
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.

- description
- 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.
