Clinical Trial Summary

This is phase 2 study of the immunomodulatory drug, lenalidomide, to evaluate potential beneficial effects on the immune system of patients with chronic lymphocytic leukemia (CLL) and CLL-associated immunodeficiency. 17 patients will be enrolled with CLL, small lymphocytic lymphoma (SLL), or monoclonal B-cell lymphocytosis (MBL), and measurable immune compromise, but not an iwCLL indication for CLL therapy (ie non-progressive disease).

Description:

This is phase 2 study of the immunomodulatory drug, lenalidomide, to evaluate potential beneficial effects on the immune system of patients with chronic lymphocytic leukemia (CLL) and CLL-associated immunodeficiency. 17 patients will be enrolled with CLL, small lymphocytic lymphoma (SLL), or monoclonal B-cell lymphocytosis (MBL), and measurable immune compromise, but not an iwCLL indication for CLL therapy (ie non-progressive disease). Lenalidomide will be administered orally for 21 days of each 28 day cycle, starting at a 2.5mg dose, with dose escalation each cycle to a maximum of 25mg in the absence of any grade 2 or higher hematologic or non-hematologic adverse events. Treatment duration to primary endpoint assessment is 6 cycles, though patients will not be restricted from continuing lenalidomide off-study, if clinically indicated

6. Women of childbearing potential (not postmenopausal for at least one year or not surgically incapable of bearing children) must agree not to become pregnant for the duration of the study. Both men and women must agree to use a barrier method of contraception for the duration of the study and until 8 weeks after the final dose of lenalidomide.

7. ECOG performance status of 0-2.

Exclusion Criteria:

1. Progressive CLL requiring therapy based on 2008 international working group guidelines (iwCLL 2008, Hallek et al, Blood 2008).

2. Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogenic adverse events as seen in animal/human studies.

3. Known hypersensitivity to thalidomide or lenalidomide.

4. Prior lenalidomide-associated deep vein thrombosis

12. Known history of IgA or IgG monoclonal gammopathy of undetermined significance (MGUS)

13. Known central nervous system (CNS) involvement by malignancy.

14. Untreated autoimmunity such as autoimmune hemolytic anemia, or immune thrombocytopenia.
