简要总结
The goal of this clinical research study is to learn if it is possible to collect stem cells after ofatumumab and chemotherapy treatment. This study will also evaluate side-effects, number of stem cells collected, and the number of procedures that are needed to collect enough stem cells.
详细描述
The Study Drugs:
Ofatumumab is a human monoclonal antibody for the CD20 protein designed to bind to the surface of some of the white blood cells (B-cells). It can destroy cancer cells that come from B-cells, and can be used to treat cancers of B-cells such as resistant CLL (chronic lymphocytic leukemia).
Etoposide is designed to slow or stop the growth of cancer cells.
Filgrastim promotes the growth of white blood cells, which help to fight infections.
Ifosfamide is designed to slow or stop the growth of cancer cells.

研究组 & 干预措施
Ofatumumab + Stem Cell Collection
Ofatumumab 1000 mg by vein on Day 1 and 2000 mg by vein on Day 8. Ifosfamide 3.33 gm/m2 by vein on Days 2, 3, and 4 continuously. Etoposide 150 mg/m2 by vein over 2 hours every 12 hours for 6 doses. Mesna 2 gm/m2 by vein over 1 hour on Day 2 (given before Ifosfamide starts). Mesna 2.66 gm/m2/day by vein continuous infusion given over 24 hours daily for 3 days starting on Day 2 (together with Ifosfamide). After Ifosfamide/Mesna, 2 gm/m2 by vein given over 12 hours for one dose. G-CSF 6 mcg/kg subcutaneously twice a day on day 6 (rounded off to the nearest vial) until completion of apheresis. Blood stem cells will be collected when blood counts have returned to normal (about 10-16 days after chemotherapy). Stem cell collection takes about 4 hours each time.

主要结局
Mobilization Rate
时间窗: Mobilization rate measured on Day 21
Feasibility of mobilization with ofatumumab + chemotherapy is defined as successful collection of 2 x 10\^6CD34+ stem cell/kg and successful purging of the apheresis product of all the markers (i.e., monoclonal B-cells, bcl-2, bcl-1 and/or JH) that were found to be positive on pretreatment evaluation. Mobilization rate is number of participants with successful collection out of total study participants.
