简要总结
This phase I/II trial studies the side effects and best dose of vorinostat when given together with fludarabine phosphate, cyclophosphamide, and rituximab and to see how well they work in treating patients with previously untreated B-cell chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). 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, may block cancer growth in different ways by targeting certain cells. Giving vorinostat together with fludarabine phosphate, cyclophosphamide, and rituximab may be a better treatment for CLL or SLL.
详细描述
PRIMARY OBJECTIVES:
I. To estimate the maximum tolerated dose (MTD) of vorinostat that can be combined with fludarabine (fludarabine phosphate), cyclophosphamide and rituximab (FCR) in patients with previously untreated CLL/SLL.
II. To evaluate potential efficacy in terms of 2-year after FCR plus vorinostat induction followed by rituximab plus vorinostat maintenance therapy for previously untreated CLL/SLL patients.
SECONDARY OBJECTIVES:
I. To eliminate residual disease (documented by flow cytometry and/or polymerase chain reaction [PCR]) in patients who have achieved a complete response (CR) after FCR plus vorinostat.

结局指标
主要结局
Percentage of Patients With Progression-free Survival at 2 Years
时间窗: 2 years
Progression-free survival (PFS): The length of time during and after the treatment that a patient lives with the disease but it does not get worse. Progressive disease is specified by the NCI (National Cancer Institute) working group guidelines and additional CT (computerized tomography) scan requirements: Lymphadenopathy, \> 50% increase in the sum of the products of at least two lymph nodes on two consecutive determinations; one lymph node must be at least 2 cm. An increase in the liver or spleen size by 50% or more by CT scan or the de novo appearance of hepatomegaly or splenomegaly. An increase in the number of blood lymphocytes by 50% or more with at least 5000 B lymphocytes per microliter. Transformation to a more aggressive histology or occurrence of cytopenia (neutropenia, anemia, or thrombocytopenia) attributable to CLL.
Maximum Tolerated Dose (MTD) of Vorinostat That Can be Combined With Fludarabine Phosphate, Cyclophosphamide and Rituximab (FCR) (Phase I)
时间窗: 28 days
The MTD of vorinostat in combination with FCR will be defined as the dose level immediately below the dose level at which greater than or equal to 2 patients out of 6 of a cohort experience dose-limiting toxicity. Toxicities will be assessed using the National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0. Doses of vorinostat analyzed to reach the MTD were 200 mg, 300 mg and 400 mg.
Overall Survival
时间窗: 2 years
Overall survival (OS): The percentage of people in a study who are still alive at for a certain period of time after they started treatment.
