Trial Information

Fludarabine, Cyclophosphamide, Rituximab and Bevacizumab in the Treatment of Relapsed Chronic Lymphocytic Leukemia

During the study, you will have up to 6 "cycles" of treatment. A cycle is made up of
treatment with the study drugs for 3-4 days and then about 3-1/2 weeks (25 days) of no
treatment (about 4 weeks total). Treatment with the study drugs will be given for 4 days in
a row on the first cycle, and 3 days in a row on Cycles 2-6. On Day 1 of each cycle, you
will receive rituximab through a needle in a vein. On Cycle 1, since it is your first
exposure to rituximab, it must be given slowly, so it may take 6-8 hours to complete. On
the cycles after that, it can be given more rapidly, over 3-4 hours. Cyclophosphamide and
fludarabine will be given separately through a needle in a vein on Days 2-4 of Cycle 1 and
Days 1-3 of Cycles 2-6. Cyclophosphamide and fludarabine will each be given over 30
minutes. Bevacizumab will be given through a needle in a vein over 90 minutes on Day 3 of
Cycle 1. If it is well tolerated, the next dose of Bevacizumab will be given over 60
minutes on Day 2 of Cycle 2. If the Cycle 2 dose is well tolerated, the next doses of
Bevacizumab will be given over 30 minutes on Day 2 of Cycles 2-6. In addition to the study
drugs, you may also be given fluids by vein to help flush the kidneys, to help prevent
possible kidney damage. You may receive up to 6 cycles of treatment. Treatment will be
given on an outpatient basis. The injections for each daily treatment visit should take
less than 6 hours.

Up to 66 patients will take part in the study. All will be enrolled at M.D. Anderson.
