I. To define the maximum tolerated dose (MTD) of ibrutinib in combination with rituximab and lenalidomide in primary central nervous system lymphoma (PCNSL) and secondary central nervous system lymphoma (SCNSL) patients.
I. To determine the safety and tolerability of ibrutinib in combination with rituximab and lenalidomide in PCNSL and SCNSL patients by assessing the frequency and severity of adverse events.
II. To assess the progression free survival at 16 weeks (PFS16w), 24 weeks (PFS24w) and 48 weeks (PFS48w).
III. To assess the duration of response (DOR) and overall survival (OS) in patients with PCNSL and SCNSL receiving ibrutinib, rituximab and lenalidomide.
IV. To explore the therapeutic efficacy using overall response rate (ORR) on magnetic resonance imaging (MRI) and/or cerebrospinal fluid (CSF) studies.
I. To correlate drug response to lymphoma subgroups and BCR signaling pathway activation status.
II. To correlate drug response to expression of cerebron.
III. To characterize mutational abnormalities and correlate with treatment response.
IV. To correlate apparent diffusion coefficient (ADC)/diffusion-weighted imaging (DWI)/perfusion MRI imaging changes to response to ibrutinib.
OUTLINE: This is a dose-escalation study of lenalidomide and ibrutinib.
Patients receive rituximab intravenously (IV) on day 1 of cycles 1-6, lenalidomide orally (PO) once daily (QD) on days 1-21 of cycles 1-12, and ibrutinib PO QD on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days then every 3 months thereafter.
