Natural Killer (NK) Cells in Cord Blood Transplantation
The goal of this clinical research study is to learn if giving cells called natural killer (NK) cells after receiving fludarabine, melphalan, lenalidomide, and a UCB transplant can improve response in patients with CLL. The safety of this treatment and whether NK cells can lessen the risk of graft vs. host disease (GVHD) will also be studied.
The first 3 patients enrolled on this study will not receive NK cells but will receive a cord blood transplant.
UCB and NK cells may be able to kill leukemia cells that remain in your body after chemotherapy treatment.
The UCB cells are also designed to increase blood production and strengthen your immune system.
Fludarabine and melphalan are designed to interfere with the DNA (genetic material) of cancer cells, which may cause the cancer cells to die.
Lenalidomide is being used in this study because it may increase the NK cell activity.

- Success Rate [ Time Frame: 3 months ] [ Designated as safety issue: No ]Success is ability to generate adequate NK cells in a patient (a minimum of 3x10e8 natural killer (NK) cells). Success Rate is number of participants achieving success divided by total participants.
- Treatment-Related Mortality (TRM) [ Time Frame: 100 days ] [ Designated as safety issue: No ]100-day treatment-related mortality (TRM) following the methods described by Thall et al.
|Study Start Date:||May 2013|
|Estimated Primary Completion Date:||May 2015 (Final data collection date for primary outcome measure)|
Experimental: CB NK + Chemotherapy
Lenalidomide 10 mg by mouth day -8 to -2. Fludarabine 40 mg/m2 intravenous (IV) from day -7 to -4. Melphalan 140 mg/m2 IV on day -4. The NK cell infusion will be administered intravenously on day -2 over a period of 30 minutes. The NK dose infused will be 5x 106/kg. Remaining cells will be discarded if not needed for laboratory studies. On Day 0, unmanipulated products (smaller cord blood unit and remnant of the larger unit) infused. Tacrolimus 0.03 mg/kg or 0.015 mg/kg (ideal body weight) by vein starting on Day -2 and tapered around Day +180 if no GvHD is present. Mycophenolate mofetil 15 mg/kg (actual body weight with a maximum dose of 1 gram twice daily) by vein or by mouth Days -3 to Day +100 in the absence of GvHD.
10 mg by mouth on days -8 to -2.
