Trial Information
Phase II Trial of Dasatinib With Fludarabine and Rituximab in Relapsed and Refractory Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma
- Since the purpose of the study is to determine the response rate of the 3 drug regimen,
everyone who participates will receive the same dose of the study drug, dasatinib and
the 2 standard drugs, fludarabine and rituximab.
- Participants will receive the drugs dasatinib, fludarabine, and rituximab at the
following time points through each cycle of treatment. A cycle of study treatment is
28 days. Dasatinib pills will be taken orally each day for the first 2 weeks of each
cycle. Fludarabine will be give intravenously on three days of each cycle (Days 3-5 in
the first cycle, days 1-3 after that). Rituximab will be given intravenously with a
total dose of 375 mg/m2 each cycle (split on Days 3+4 in the first cycle and at the
discretion of the treating physician after that on Days 1-3).
- The following procedures will be repeated throughout the study: medical history
review; physical exam; performance status test; blood tests and EKG. They will occur
daily during the first week of treatment, then weekly for the rest of cycle 1. After
cycle 1 these procedures will be done once a week for 4 weeks then once a month for 6
months.
- Tumor assessments will be repeated once every 2 months for the first six months of the
study, and then once every 6 months after that.
- Blood samples will be obtained in the first 5 days of treatment for pharmacokinetic
studies and pharmacodynamic studies.
- Participants that are benefiting from the study treatment after the first cycle can
continue to receive an additional 6 cycles of study treatment.
Inclusion Criteria:
- CLL/SLL with cells positive by flow cytometry (or immunostaining) for CD19, CD23, and

t(11;14) negative.
- Participants must have received at least 1 prior regimen containing a purine analogue
or have received at least 2 chemotherapy regimens not containing a purine analogue.
Patients may be refractory to single-agent purine analogue treatment, but patients
may not be refractory to a combination of purine analogue with rituximab. Patients
