Chronic Lymphocytic Leukemia Clinical Trial
Lenalidomide and Obinutuzumab in Treating Patients With Recurrent or Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma
This phase II trial studies how well lenalidomide and obinutuzumab work in treating patients with leukemia-cll/" >chronic lymphocytic leukemia or small lymphocytic lymphoma that has come back (recurrent) or does not respond to treatment (refractory). Drugs used in chemotherapy, such as lenalidomide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Monoclonal antibodies, such as obinutuzumab, may interfere with the ability of cancer cells to grow and spread. Giving lenalidomide and obinutuzumab may work better in treating patients with chronic lymphocytic leukemia or small lymphocytic lymphoma.
I. Overall response defined as achievement of complete response (CR) or partial response (PR).
I. Safety of the combination. II. Response according to prognostic markers at diagnosis. III. Time to next treatment. IV. Overall survival.
Patients receive obinutuzumab intravenously (IV) over 3-4 hours on days 1, 2, 8, and 15 of course 1 and day 1 of courses 2-6 and lenalidomide orally (PO) once daily (QD) on days 9-28 of course 1 and days 1-28 of all subsequent courses. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. Patients may continue to receive lenalidomide PO QD in the absence of disease progression or unacceptable toxicity.

Females of childbearing potential (FCBP) must have a negative serum and/or urine pregnancy test with a sensitive of at least 50 mIU/mL within 10-14 days and again within 24 hours prior to prescribe lenalidomide for cycle 1 (prescriptions must be filled within 7 days as required by Revlimid REMS) and must either commit to continued abstinence from heterosexual intercourse or begin TWO acceptable methods of birth control, one highly effective method and one additional effective method AT THE SAME TIME, at least 28 days before she starts taking lenalidomide; FCBP must also agree to ongoing pregnancy testing; men must agree to use a latex condom during sexual contact with a FCBP even if they have had a successful vasectomy
