Trial Information

A Phase II Study of Sunitinib Malate for Treatment of Patients With Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)


I. Assess the response rate (complete response [CR] and partial response) in patients with
relapsed or refractory chronic lymphocytic leukemia or small lymphocytic lymphoma treated
with sunitinib malate.

II. Assess the toxicity of this drug in these patients. III. Assess duration of response,
time to progression, overall survival, and CR rate in patients treated with this drug.


I. Evaluate if known risk stratification parameters (i.e., immunoglobulin mutational status,
ZAP-70 status, fluorescent in situ hybridization [FISH] defects, and/or CD38 status) are
related to clinical response to sunitinib malate.

OUTLINE: This is a multicenter study.

Patients receive oral sunitinib malate daily on days 1-28. Treatment repeats every 28 days
for up to 12 courses in the absence of disease progression or unacceptable toxicity.

Patients undergo blood collection periodically for translational and pharmacological
studies, including IgVH gene mutation status and ZAP-70 status. Samples are examined by
fluorescent in situ hybridization (FISH) and other assays.

After completion of study treatment, patients are followed every 3 months for up to 2 years.

Inclusion Criteria:

- Diagnosis of 1 of the following:

- Biopsy proven small lymphocytic lymphoma (SLL)

- Chronic lymphocytic leukemia (CLL) meeting all of the following criteria:

- Lymphocytes must consist of small to moderate size lymphocytes, with < 55%
prolymphocytes, atypical lymphocytes, or lymphoblasts morphologically

- Immunophenotyping consistent with CLL, defined by the following criteria:

- Predominant population of lymphocytes share both B-cell antigens
(i.e., CD19, CD20, or CD23) as well as CD5 in the absence of other
pan-T-cell markers (e.g., CD3 or CD2)

chlorambucil) regimen
