A Phase I Study of Rituximab, Lenalidomide, and Ibrutinib in Previously Untreated Follicular Lymphoma

This phase I trial studies the side effects and best dose of lenalidomide and ibrutinib when given together with rituximab in treating patients with previously untreated stage II-IV follicular lymphoma. Lenalidomide may stimulate 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. It binds to a protein called CD20, which is found on B cells (a type of white blood cell) and some types of cancer cells. This may help the immune system kill cancer cells. Giving lenalidomide and ibrutinib together with rituximab may work well in treating follicular lymphoma.


     I. To determine the recommended phase II doses of ibrutinib and lenalidomide for combination with rituximab in previously untreated follicular lymphoma.


     I. To determine pharmacokinetics of ibrutinib and its major metabolite (PCI-45227) when combined with lenalidomide and rituximab.

     II. To determine the pharmacodynamics of basophil activation and Bruton tyrosine kinase (BTK) occupancy in peripheral blood mononuclear cells (PBMCs) over a 24-hour period of ibrutinib when given in combination with lenalidomide and rituximab.

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

     Patients receive lenalidomide orally (PO) once daily (QD) on days 1-21 and ibrutinib PO QD on days 1-28. Treatment repeats every 28 days for up to 18 cycles in the absence of disease progression or unacceptable toxicity. Patients also receive rituximab intravenously (IV) on days 1, 8, 15, and 22 of cycle 1 and once weekly at weeks 13, 21, 29, and 37.

     After completion of study treatment, patients are followed up every 4 months for 2 years and then every 6 months for 8 years or every 6 months or annually for 10 years.
