Lenalidomide belongs to a group of drugs called immunomodulatory drugs (IMiD) that can modify or regulate the functioning of the immune system. It is an FDA approved drug for people with multiple myeloma. It is not currently approved for use in Chronic Lymphocytic Leukemia (CLL), but it does appear effective in CLL when used alone, and is being studied for use in combination with chemotherapy in this and other lymphomas and leukemias.

In this research study we are hoping to learn more about the effects of lenalidomide on CLL when given in combination with bendamustine and rituximab, which is a highly effective regimen for initial therapy of CLL/SLL. The investigators will be looking for the highest dose of lenalidomide that can be given safely, without causing any serious or unmanageable side effects.

Additional Information

Official title Lenalidomide in Combination With Bendamustine and Rituximab for Previously Untreated Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma(CLL/SLL): a Phase I Study
Principal investigator Jeremy Abramson, M.D.
Description Subjects will receive lenalidomide, bendamustine and rituximab in cycles of 28 days (4 weeks). Lenalidomide will be administered orally once daily on days 8-21 of cycle 1 and on days 1-21 of all subsequent cycles. Bendamustine will be administered through a vein (IV infusion) on days 1 and 2 of each cycle. Rituximab will be administered as an IV infusion on day 1 of each cycle. Subjects will receive routine blood tests and physical exam during each cycle. Tumor assessments by CT scan will be performed during cycles 2, 4, and 6.
