Inclusion criteria
* Participants must be able to understand and be willing to sign a written informed consent document. * Subjects must be at least 18 years of age on the day of consenting to the study. * Histologically documented PCNSL or SCNSL. Patients with SCNSL need to have cytology or tissue biopsy documenting lymphomatous involvement of the CNS * Patients must have relapsed/refractory PCNSL or relapsed/refractory SCNSL * All patients need to have received at least one prior CNS directed therapy. There is no restriction on the number of recurrences. * Patients with parenchymal lesions must have unequivocal evidence of disease progression on imaging (MRI of the brain or head CT) 21 days prior to study registration. For patients with leptomeningeal disease only, CSF cytology must document lymphoma cells and/or imaging findings consistent with CSF disease 21 days prior to study registration. * Participants must have a Karnofsky performance status (KPS) of ≥ 50. * Participants must have adequate bone marrow and organ function shown by: Absolute neutrophil count (ANC) ≥ 1.5x 109/L * Platelets ≥ 100 x 109/L and no platelet transfusion within the past 14 days prior to study registration * Hemoglobin (Hgb) ≥ 9 g/dL and no red blood cell (RBC) transfusion within the past 14 days prior to study registration * International Normalized Ratio (INR) ≤ 1.5 * Alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 1.5 times the ULN. * Serum bilirubin ≤ upper limit of normal; or total bilirubin ≤ 2.0x the ULN with direct bilirubin within the normal range in patients with well documented Gilbert Syndrome. * Participants must be able to take oral medication. * Patients must be able to tolerate MRI scans. * Patients must be able to tolerate lumbar puncture and/or Ommaya taps. * Participants must have recovered to grade 1 toxicity from prior therapy. * Participates must be able to submit 20 unstained slides from the initial tissue diagnosis for confirmation of diagnosis and correlative studies * Life expectancy of \> 3 months (in the opinion of the investigator) Note: Prior autologous stem cell transplant as well as radiation to the CNS is NOT an exclusion criterion. Prior allogenic stem cell transplant IS an exclusion criterion.
