High-dose Methylprednisolone and Rituximab in High Risk B-CLL

Studies have shown that both high-dose Methylprednisolone and Rituximab used as single agents are effective in relapsed and refractory B-CLL. Methylprednisolone acts independently of p53 apoptosis pathway. The combination of both drugs may improve response and outcome in previously treated high-risk B-CLL patients. Study Objectives Primary: To determine the clinical benefit of high-dose Methylprednisolone and Rituximab in previously treated high-risk B-CLL patients in terms of clinical and flowcytometric response rate. Secondary: To determine progression free and overall survival. To characterize the safety profile of high-dose Methylprednisolone and Rituximab.
