Dasatinib in Treating Patients With Chronic Lymphocytic Leukemia

Completed · Phase 2

Conditions studied: Refractory Chronic Lymphocytic Leukemia, Stage I Chronic Lymphocytic Leukemia, Stage II Chronic Lymphocytic Leukemia, Stage III Chronic Lymphocytic Leukemia, Stage IV Chronic Lymphocytic Leukemia

In brief

This phase II trial studies how well dasatinib works in treating patients with chronic lymphocytic leukemia (CLL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
