A Phase I Study of Ibrutinib (PCI-32765) in Combination With Lenalidomide in Relapsed and Refractory B-Cell Non-Hodgkin's Lymphoma
This phase I trial studies the side effects and best dose of lenalidomide and ibrutinib in treating patients with B-cell non-Hodgkin lymphoma that has returned or not responded to treatment. Biological therapies, such as 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. Giving lenalidomide with ibrutinib may work better in treating non-Hodgkin lymphoma than giving either drug alone.
I. To determine the dose limiting toxicity (DLT) and maximum tolerated dose (MTD) of the combination of lenalidomide and ibrutinib in patients with relapsed and refractory B-cell non-Hodgkin's lymphoma (NHL).
II. To define the qualitative and quantitative toxicities of the combination of lenalidomide and ibrutinib.
I. To describe the overall objective response rate to the combination of lenalidomide and ibrutinib in patients with relapsed or refractory B-cell NHL.
II. To describe the response duration and two-year progression free survival (PFS) in patients with B-cell NHL receiving lenalidomide and ibrutinib.
III. To characterize the pharmacokinetics of the combination of lenalidomide and ibrutinib in patients with relapsed or refractory B-cell NHL.
IV. To identify associations of genetic polymorphisms in drug metabolizing enzymes, transporters or target genes with pharmacokinetics, pharmacodynamics, and clinical outcomes.
V. To monitor the effects of combined therapy with ibrutinib and lenalidomide on B- T-, and natural killer (NK)-cell subsets by flow cytometry and quantitative immunoglobulin levels.
VI. To explore the effects of the combination of ibrutinib and lenalidomide on pharmacodynamic markers including T helper cell, type 1 (TH1) and T helper cell, type 2 (TH2) cytokines, ex vivo NK cell cytotoxicity, serum micro ribonucleic acids (RNAs), plasma metabolites, and levels of Bruton's tyrosine kinase occupancy and other selected kinases.
VII. To explore the relationship between pretreatment pathologic prognostic features and overall objective response.
OUTLINE: This is a dose-escalation study.
Patients receive lenalidomide orally (PO) on days 1-21 and ibrutinib PO on days 1-28 (days 2-28 of cycle 1). Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up for 4 weeks and then every 6 months thereafter.
18 Years and up
