Vorinostat + Chemotherapy for CLL or SLL (PSOC-2401)
A Phase I/II Study of Fludarabine (F), Cyclophosphamide ©), Rituximab ®), and Vorinostat (V) Followed by RV Maintenance Therapy in Patients With Previously Untreated B-Cell Chronic Lymphocytic Leukemia or Small LymphoCtic Lymphoma (SLL)
Status Conditions Phase Study ID
Closed Leukemia
Phase I/II PSOC-2401

RATIONALE: Vorinostat may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fludarabine phosphate and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as rituximab, 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 vorinostat together with fludarabine phosphate, cyclophosphamide, and rituximab may kill more cancer cells.

PURPOSE: This phase I/II trial is studying the side effects and best dose of vorinostat when given together with fludarabine phosphate, cyclophosphamide, and rituximab and to see how well it works in treating patients with previously untreated B-cell chronic lymphocytic leukemia or small lymphocytic lymphoma.
