研究概览
简要总结
The goal of Phase 1 of this clinical research study is to find the highest tolerable dose of bendamustine, combined with fludarabine and rituximab, that can be given to patients who have CLL that has been treated before.
The goal of Phase 2 of this study is to find out if this drug combination can help to control the disease. The safety of this drug combination will also be studied.
详细描述
The Study Drugs:
Fludarabine and bendamustine are designed to damage the DNA (genetic material) of cancer cells, which may cause the cancer cells to die.
Rituximab is designed to attach to cancer cells and damage them, which may cause the cancer cells to die. It is also designed to cause the immune system to attack cancer cells.
Study Drug Dose Levels:
If you are found to be eligible to take part in this study, you will be assigned to a study group based on when you joined this study. One (1) to 8 groups with 3-6 participants will be enrolled in the Phase 1 portion of the study, and up to 58 participants will be enrolled in Phase 2.

结局指标
主要结局
Maximum Tolerated Dose (MTD) of Bendamustine Combined With Fixed-Dose Fludarabine and Rituximab (FBR)
时间窗: After 4 week cycle
MTD defined as highest dose level in which 6 participants have been treated with \</= to 1 patient experiencing dose limiting toxicity (DLT). MTD exceeded if 2 or more of 6 patients experience grade 3 or higher, non-hematologic, non-infusion related toxicity a major organ system. DLT defined as treatment-related, grade \>/= 3 non-hematologic toxicity. Hematologic toxicity grade \>/= 3 that lasts longer than 42 days considered a DLT. Hematologic toxicity graded according to the 2008 IWCLL criteria for grading. Tumor lysis not considered a DLT.
次要结局
- Overall Response Rate of Bendamustine Combined With Fixed-Dose Fludarabine and Rituximab (FBR)(Overall response assessed 2 months after 6th or last course if participants not able to receive all 6 intended courses of treatment.)
