SECONDARY outcome

Timeframe: 2 years

Dasatinib may enhance the myelosuppression expected from fludarabine. This toxicity will be monitored with frequent CBC's. If after Day 21 of a cycle there is a grade 4 cytopenia, a dose reduction will occur in the next cycle of treatment, and that cycle cannot start until the ANC \> 1,000 and the platelets \> 25,000. There is also a risk for pleural effusions with dasatinib, but the risk will be low, since there is a break from dasatinib dosing on days 15-28 of each cycle. Nevertheless, if a grade 2 pleural effusion occurs, there will be a dose reduction in the next cycle of treatment.
