Ofatumumab With High Dose Methylprednisone Followed by Ofatumumab and Alemtuzumab in 17p CLL

The main purpose of this study is to examine how two separate groups of 17p deletion Chronic lymphocytic leukemia (CLL) participants respond to sequential treatment with this particular combination of drugs. The two groups are those participants who have previously received treatment for their CLL and those who have not yet received any treatment. The combination of drugs is Ofatumumab and High-Dose Methylprednisolone (HDMP) first followed by Ofatumumab and Alemtuzumab. All three drugs are FDA approved and have known activity in treating 17p CLL. We hope that by combining these drugs together in this study, they will have more benefit than each one alone and that the subjects' CLL will be significantly impacted.
