Spots Global Cancer Trial Database for Ibrutinib With or Without Rituximab in Treating Patients With Relapsed Chronic Lymphocytic Leukemia

Study Description

Brief Summary: This phase II trial studies ibrutinib with or without rituximab in treating patients with chronic lymphocytic leukemia that has come back after treatment. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as rituximab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether ibrutinib is more effective with or without rituximab in treating chronic lymphocytic leukemia.

Detailed Description: PRIMARY OBJECTIVE: I. To compare the 2-year progression-free survival (PFS) rate in treated patients. SECONDARY OBJECTIVE: I. To determine safety and tolerability, the overall response rate (ORR), the estimated PFS, changes in immune parameters (lymphocyte subpopulations, immunoglobulin levels) and biomarker responses in relapsed chronic lymphocytic leukemia (CLL) patients receiving ibrutinib (i) versus ibrutinib and rituximab (iR). OUTLINE: Patients are randomized to 1 of 2 arms. ARM I: Patients receive ibrutinib orally (PO) once daily (QD) on days 1-28 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. ARM II: Patients receive ibrutinib as in Arm I beginning on day 1 or 2. Patients also receive rituximab intravenously (IV) over 3-8 hours on days 1, 8, 15, and 22 of cycle 1 and day 1 of cycles 2-6. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 60 days and then every 4 months for 5 years.
