- Brief Summary
The purpose of this study is to test any good or bad effects of the study drug called of ibrutinib (also known as Imbruvica™). At this stage of this trial, the study is investigating whether Ibrutinib can be incorporated into the established first-line chemotherapy regimen rituximab, methotrexate, vincristine, and procarbazine (R-VMP) in order to further refine the first-line induction therapy for PCNSL, as observed by a superior CRR (complete response rate) (ARM D RECRUITING ONLY)

- Primary Outcome Measures
Name Time Method define the Maximum Tolerated Dose (MTD) of ibrutinib (phase I) 1 year A standard 3+3 design will be employed. Three dose levels of ibrutinib will be investigated. Patients will be treated in cohorts of size three to six and the dosage will be escalated if the clinical toxicity is acceptable. A dose-limiting toxicity (DLT) is defined as in any of the following during cycle 1: any grade 4 hematologic toxicity, grade 3 febrile neutropenia and grade 3 thrombocytopenia associated with bleeding or any grade 3 non-hematologic toxicity that does not respond to supportive therapy and at least possibly related to treatment with ibrutinib.
progression free survival (phase II) 2 years Progression-free survival (PFS) is defined as the time from the date of treatment start to the date of the first documented PD or death due to any cause.
define the Maximum Tolerated Dose (MTD) of ibrutinib in combination with high-dose Methotrexate (HD-MTX) 1 year Three patients with PCNSL or SCNSL will be treated with daily oral ibrutinib +/- HD-MTX for a 28-day cycle starting at dose level 1 and observed for toxicities for a minimum of 4 weeks. Dose-limiting toxicity (DLT) will be defined as any grade 4 hematologic toxicity, grade 3 febrile neutropenia and grade 3 thrombocytopenia associated with bleeding as well as any grade 3 non-hematologic toxicity that does not respond to supportive therapy and at least possibly related to ibrutinib. If no DLT is observed in any of the 3 treated patients, we will escalate to the next dose level.
