Summary

RATIONALE: Monoclonal antibodies, such as alemtuzumab and rituximab, can kill chronic lymphocytic leukemia (CLL) cells and are effective therapies for this disease. Biological therapies, such as Imprime PGG (poly-(1-6)-beta-glucotriosyl-(1-3)-beta-glucopyranose), may stimulate the immune system in different ways and help monoclonal antibodies kill CLL cells. Giving PGG beta-glucan together with alemtuzumab and rituximab could make therapy with monoclonal antibodies, such as alemtuzumab and rituximab, more effective.

PURPOSE: This phase I/II trial is studying the side effects and best dose of PGG beta-glucan when given together with alemtuzumab and rituximab and to see how well it works in treating patients with earlier stage high-risk chronic lymphocytic leukemia.
