Chronic Lymphocytic Leukemia Clinical Trial

Lenalidomide, Ibrutinib, and Rituximab in Treating Patients With Relapsed or Refractory Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma That Is Metastatic or Cannot Be Removed by Surgery

Summary

This phase I trial studies the side effects and best dose of lenalidomide when given together with ibrutinib and rituximab in treating patients with leukemia-cll/" >chronic lymphocytic leukemia or small lymphocytic lymphoma that has come back (relapsed), has not responded well to prior treatments (refractory), has spread to other parts of the body (metastatic), or cannot be removed by surgery. Biological therapies, such as lenalidomide, use substances made from living organisms that may stimulate or suppress the immune system in different ways and stop cancer cells from growing. Ibrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Rituximab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. Giving lenalidomide together with ibrutinib and rituximab may kill more cancer cells.

PRIMARY OBJECTIVE:

I. To determine the recommended phase II doses of lenalidomide and ibrutinib for combination with rituximab in previously treated chronic lymphocytic leukemia and small lymphocytic lymphoma.

SECONDARY OBJECTIVES:

I. To determine the safety and tolerability of the combination of lenalidomide, ibrutinib and rituximab in previously treated chronic lymphocytic leukemia and small lymphocytic lymphoma.

II. To describe any preliminary evidence of antitumor activity of the combination of lenalidomide, rituximab and ibrutinib in previously treated chronic lymphocytic leukemia and small lymphocytic lymphoma as defined by response rate, duration of response, and progression-free survival.

III. To observe and record anti-tumor activity.

OUTLINE: This is a dose-escalation study of lenalidomide.

Patients receive rituximab intravenously (IV) on day 1 (up to 6 cycles), lenalidomide orally (PO) once daily (QD) on days 1-21 (up to 12 cycles), and ibrutinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

Patients undergo electrocardiogram (ECG) on screening and computed tomography (CT) scan or magnetic resonance imaging (MRI), bone marrow biopsy and blood sample collection throughout the study.

After completion of study treatment, patients are followed up at 30 days and every 6 months for 10 years.

Pregnant and breastfeeding women are excluded from this study; pregnant women are excluded in this study because ibrutinib is a tyrosine kinase inhibitor with the potential for teratogenic or abortifacient effects; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with ibrutinib, breastfeeding should be discontinued if the mother is treated with ibrutinib
