Brief Summary
This phase II trial is studying how well bevacizumab works in treating patients with relapsed or refractory B-cell chronic lymphocytic leukemia. Monoclonal antibodies, such as bevacizumab, 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. Bevacizumab may also stop the growth of cancer cells by blocking blood flow to the cancer.

Outcome Measures
Primary Outcomes (1)
Number of Patients With Confirmed Objective Status of Complete Response (CR), Complete Clinical Response (CCR), Nodular Partial Response (nPR), or Partial Response (PR).
The NCI Working Group criteria will be used to assess response to therapy. A confirmed response is defined as a response documented on 2 consecutive evaluations at least 4 weeks apart. Complete Response: * No lymphadenopathy * No hepatomegaly or splenomegaly * Absense of constitutional symptoms * Polymorphonuclear leukocytes ≥ 1500/ul * Platelets \> 100,000/ul * Hemoglobin \> 11.0 gm/dl * Peripheral blood lymphocytes ≤ 4000/uL. * Confirmation by Marrow Aspirate and biopsy. Complete Clinical Response: -CR without bone marrow biopsy confirmation. Nodular Partial Response: -CR with the presence of residual clonal nodules. Partial Response requires: * ≥ 50% decrease in peripheral blood lymphocyte count * ≥ 50% reduction in lymphadenopathy * ≥ 50% reduction in size of liver and/or spleen * 1 or more of the following: * Polymorphonuclear leukocytes ≥ 1500/ul * Platelets \>100,000/ul * Hemoglobin \>11.0 gm/dl
Up to 5 years
Secondary Outcomes (3)
Toxicity Associated With This Regimen in Participants With Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL).
From the date of registration to the to the date of last treatment evaluation, median number of days on treatment was 56 days.
Overall Survival
From the date of registration to the date of the event (i.e., death or the date of last follow-up), up to 5 years.
Time to Progression
From the date of registration to the date of the event (i.e., death or disease progression) or the date of last follow-up, up to 5 years
Study Arms (1)
Treatment (monoclonal antibody therapy)
EXPERIMENTALPatients receive bevacizumab IV over 30-90 minutes on days 1 and 15. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Interventions
Given IV
Eligibility Criteria
You may qualify if:
- Diagnosis of B-cell chronic lymphocytic leukemia (CLL)\*, as defined by the following phenotypic characteristics:
- Predominant population of cells share both B-cell antigens (CD19, CD20, or CD23) as well as the T-cell antigen (CD-5), in the absence of other pan-T-cell markers (CD-3, CD-2, etc.)
- Mantle cell lymphoma must be excluded by demonstrating the absence of the t(11;14) by fluorescent in situ hybridization (FISH)
- Dim surface immunoglobulin expression
- Exclusively kappa and lambda light chains
- Peripheral blood absolute lymphocyte count \> 5,000/mm\^3
- Lymphocytosis must consist of small to moderate size lymphocytes, with ≤ 55% prolymphocytes, atypical lymphocytes, or lymphoblasts morphologically
- Requires chemotherapy, as indicated by any of the following:
- Disease related symptoms, including the following:
- Weight loss ≥ 10% within the previous 6 months
- Extreme fatigue
- Fevers \> 100.5°F for 2 weeks without evidence of infection
- Night sweats without evidence of infection
- Evidence of progressive marrow failure, as manifested by the development of or worsening anemia (hemoglobin ≤ 10 g/dL) and/or thrombocytopenia (platelet count ≤ 100,000/mm\^3)
- Massive (i.e., \> 6 cm below left costal margin) or progressive splenomegaly
- +36 more criteria
