Pentostatin, and Rituximab With and Without Cyclophosphamide for Previously Untreated B-Chronic Lymphocytic Leukemia

February 6, 2017 updated by: John Byrd, Ohio State University Comprehensive Cancer Center

Phase II Trial of Pentostatin, and Rituximab With and Without Cyclophosphamide for Previously Untreated B-Chronic Lymphocytic Leukemia (CLL)

This study aims to assess the rate of complete and overall response using rituximab and pentostatin with and without cyclophosphamide, to monitor and assess toxicity of this regimen, and to determine the overall and progression-free survival in CLL patients

Detailed Description

Rationale: Research indicates that both cyclophosphamide and pentostatin work synergistically against cancer cells and have a high response rate against chronic lymphocytic leukemia (CLL) without creating severe side effects in patients. In addition, studies have shown that rituximab, a therapy that targets the immune system, has the highest efficacy against CLL and the lowest toxicity rate when compared with other immunotherapy drugs. Studies also show that rituximab enhances the efficacy of the chemotherapy agents cyclophosphamide and pentostatin. This study offers the combination of immunotherapy with two promising chemotherapy agents against CLL.

Purpose: This study is evaluating the efficacy and safety of combination treatment with cyclophosphamide, pentostatin, and rituximab in patients with CLL. Several tests evaluating the genetic and molecular components of CLL will also be performed. Some of these tests will be conducted before, during, and after treatments to assess changes resulting from the study drugs. Each patient's outcome will be assessed in relation to various aspects of their genes.
