A Randomized Study to Assess the Effect on Response Rate of MabThera (Rituximab) Added to a Standard Chemotherapy, Bendamustine or Chlorambucil, in Patients With Chronic Lymphocytic Leukemia
This randomized, open-label, parallel group study will assess the effect on response rate and the safety of MabThera added to either bendamustine or chlorambucil in patients with chronic lymphocytic leukemia. Patients will be randomized to receive six 4-week cycles of either A) MabThera (375mg/m2 iv day 1 of cycle 1, 500mg/m2 iv cycles 2-6) plus bendamustine (90mg/m2 as first-line or 70mg/m2 as second-line therapy, iv on days 1 and 2, cycles 1-6), or B)MabThera plus chlorambucil (10mg/m2 po daily, days 1-7, cycles 1-6). Patients in group B can receive up to 6 further cycles of chlorambucil as monotherapy. Anticipated time on study treatment is 6-12 months, and target sample size is 600-700 individuals.

Dasatinib Combination for Chronic Lymphocytic Leukemia Patients With Chemo Refractory Disease
Patients with chemo refractory CLL have a poor prognosis. 2 independent mechanisms are attributed to the development of chemoresistance in CLL. The first is a shift in the balance between pro- and anti-apoptotic regulators. The second mechanism is based on acquired mutations resulting in a dysfunctional p53 response. Recent studies indicate that the tyrosine kinase inhibitor dasatinib acts synergistically with both purine analogies and alkylating agents. Also, dasatinib has the potency to restore the apoptotic balance of CLL cells. Hypothesis: Dasatinib will be clinically active in chemo-refractory CLL patients and will act synergistically with the purine-analogue fludarabine.

B-CLL Subgroups: Maturation Stage and Gene Expression
B type chronic lymphocytic leukemia (B-CLL) is the most prevalent leukemia in the western world. It is a disease that occurs primarily in aging individuals and occurs more frequently in males than females. Although B-CLL was considered a homogeneous condition, recent studies by our laboratory and others suggest that B-CLL cases can be divided into two subgroups. These sub-groups can be identified by either the presence or the absence of mutations in antibody genes and/or by the percentage of B-CLL cells expressing a particular protein called CD38. These two sub-groups (unmutated antibody genes high percent CD38 and mutated antibody genes low percentage CD38) follow strikingly clinically different courses. For example, the unmutated/CD38+ group experiences a much more aggressive disease and these patients almost invariably die much sooner than the cases in the other group. In addition, the patients in the mutated CD38+ group require much more chemotherapy than mutatedlCD38-. Finally, surprisingly there is a much higher representation of males in the poor outcome unmutated CD38 group than in the better outcome group. The reasons for these differences in clinical outcome and gender bias are unknown.

B Cell Repertoires in Chronic Lymphocytic Leukemia and Aging
B-CLL is the most prevalent leukemia in the Western hemisphere, accounting for ~25% of all leukemia's (1). This disease occurs virtually exclusively in the aging population, with the median age of diagnosis ranging between the mid 60s and the early 70s. Indeed, its occurrence before the age of 50 is quite unusual. This increase in occurrence with age is not unique to B-CLL; rather, it is characteristic several B cell lymphoproliferative disorders (e.g., non-Hodgkin's lymphoma, multiple myeloma). Gender and race also influence the development of B-CLL. Thus, the ratio of men: women is ~2:1 and the prevalence is increased in Caucasians. The rate of occurrence of B-CLL among Asians is significantly lower than for Caucasians and this does not increase with immigration to the West. DNA sequence analyses performed in our laboratory and in those of others indicate that B-CLL cells from unrelated patients share Ig V gene characteristics. These include the use of selected genes, the association of these genes with certain D and JH gene segments that code for unique CDR3 motifs, and the occasional occurrence of highly similar VHDJH + VLJL pairs. In ~50% cases, these rearranged genes are mutated, whereas in the others mutations are infrequent; this difference is related to the VH gene family used by the B-CLL cell.

A Phase II Randomized Trial Comparing Standard and Low Dose Rituximab: Initial Treatment of Progressive Chronic Lymphocytic Leukemia in Elderly Patients Using Alemtuzumab and Rituximab
RATIONALE: Monoclonal antibodies, such as rituximab and alemtuzumab, can block cancer growth in different ways. Some block the ability of cancer cells to grow and spread. Others find cancer cells and help kill them or carry cancer killing substances to them. Giving rituximab together with alemtuzumab may kill more cancer cells. PURPOSE: This randomized phase II trial is studying two different doses of rituximab to compare how well they work when given together with alemtuzumab in treating older patients with progressive chronic lymphocytic leukemia.

Trial of Immune Reconstitution With CD3/CD28 Bead Activated T-Cells Following Chemo-Immunotherapy in Patients With Chronic Lymphocytic Leukemia
The purpose of this research study is to test whether giving T-cells (type of white blood cell that are also known as immune cells) that have been specially processed in the laboratory will help chronic lymphocytic leukemia (CLL) patients' immune system return to normal faster after chemotherapy. This research study will also look into the ability of the lab to process the T-cells for infusion and the side effects of giving T-cells to patients with chronic lymphocytic leukemia (CLL).

A Phase II Study of Lenalidomide in Patients With Chronic Lymphocytic Leukemia Older Than 65 Years of Age
The purpose of this study is to: Determine the likelihood that lenalidomide will adequately control the disease for at least one year. Lenalidomide is a drug that alters the immune system and it may also interfere with the development of tiny blood vessels that help support tumor growth. Therefore, in theory, it may reduce or prevent the growth of cancer cells. Lenalidomide is approved by the Food and Drug Administration (FDA) for the treatment of specific types of myelodysplastic syndrome (MDS) and in combination with dexamethasone for patients with multiple myeloma (MM) who have received at least 1 prior therapy. MDS and MM are cancers of the blood. It is currently being tested in a variety of cancer conditions. In this case it is considered experimental. The lenalidomide being administered in this study is not a commercially marketed product. Although it is expected to be very similar in safety and activity to the commercially marketed drug, it is possible that some differences may exist. Because this is not a commercially marketed drug, lenalidomide can only be administered to patients enrolled in this clinical trial and may only be administered under the direction of physicians who are investigators in this clinical trial.

Molecular Markers Of Chronic Lymphocytic Leukemia
RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors identify and learn more about biomarkers related to cancer. PURPOSE: This research study is looking at biomarkers in blood and bone marrow samples from patients with previously untreated chronic lymphocytic leukemia.

A Phase I/II Clinical Trial of Lenalidomide in Combination With AT-101 for the Treatment of Relapsed B-Cell Chronic Lymphocytic Leukemia (B-CLL)
This phase I/II trial studies the side effects and best dose of lenalidomide when given together with R-(-)-gossypol acetic acid and to see how well they work in treating patients with B-cell chronic lymphocytic leukemia (B-CLL) that has returned after a period of improvement (relapsed). Biological therapies, such as lenalidomide, may stimulate the immune system to attack cancer cells. R-(-)-gossypol acetic acid may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth and causing the cells to die. Giving lenalidomide with R-(-)-gossypol acetic acid may be an effective treatment for relapsed or refractory B-CLL. - Funding Source - FDA OOPD
