Currently there is no standard of care for relapsed or refractory primary central nervous system (CNS) lymphoma. After high-dose methotrexate or radiation therapy, the best approach to relapsed disease is undefined. Common practice is the regimen RBEAM as a conditioning regimen in this patient population prior to transplantation. The RBEAM regimen includes R (rituximab), B (BCNU), E (etoposide), A (Ara-C (cytarabine)) and M (melphalan). In addition, dexamethasone is included in the regimen although not noted in the RBEAM mnemonic. However, the melphalan used in this combination is not thought to have much CNS penetration. Therefore, temozolomide, an alkylating agent known to penetrate the CNS and approved by the FDA for brain tumors will be used and evaluated in this study instead of melphalan.

The aim of this study is to determine an effective and safe dose of temozolomide orally administered to patients with relapsed primary CNS lymphoma over the 5 days preceding autologous stem-cell transplantation. The hope is that the conditioning regimen DRBEAT [D (dexamethasone) (R (rituximab), B (BCNU), E (etoposide), A (Ara-C (cytarabine)) and T (temozolomide)] will significantly improve the survival of patients with relapsed CNS lymphoma.

Primary Outcome Measures:
  • Efficacy of the DRBEAT Regimen [ Time Frame: One Year ] [ Designated as safety issue: Yes ]

    Efficacy of the DRBEAT Regimen will be assessed by analysis of

    1. one-year progression-free survival (PFS), defined as the time interval from maximal response from therapy to tumor regrowth, progression, or death,


    2. Overall survival, defined as the time interval between the date of transplant and the date of death from any cause.

  • Safest dose of temozolomide for the DRBEAT Regimen [ Time Frame: One year ] [ Designated as safety issue: Yes ]
    Safety will be assessed using a dose escalation design for temozolomide's use to determine the target dose and also to evaluate any and all acute treatment related toxicities. During the course of patient follow up and therapy, toxicities will be evaluated, particularly as the investigators will be determining the target dose of temozolomide. One of the major criteria for dose limiting toxicity for the study will be any Grade 3 or 4 nonhematologic toxicity from a list of commonly expected toxicities associated with autologous transplantation and temozolomide.

Estimated Enrollment: 20
Study Start Date: September 2010
Estimated Study Completion Date: December 2013
Estimated Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: DRBEAT Regimen Drug: Temozolomide
The DRBEAT regimen will be similar to RBEAM. Rituximab and Carmustine will be given Day -6. Etoposide and Cytarabine will be given on Days -5 to -2. Temozolomide will be given via divided doses over five days starting on Day -5 to Day -1. A dose escalation design, known as EWOC (Escalation with overdose control) will be used to determine the target dose of temozolomide for this study. The starting dose given over five days will begin at 250mg/m2 (cumulative total dose of 1250 mg/m2), as previous data indicates this to be a safe dose. Based on the reported Dose Limiting toxicities from the previous patients, the EWOC statistical modeling will be performed to determine the next dose level.

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Patients ≥ 18 years of age and ≤ 75 years of age
  • A mature B-cell lymphoma originating in the CNS, (WHO criteria)
  • Patients with relapsed or progressed disease following therapy for CNS B Cell lymphoma who has achieved a subsequent CR or PR following salvage chemotherapy
  • Patients who are initially refractory to therapy for CNS B cell lymphoma but who have achieved a CR or PR following a salvage chemotherapy regimen
  • Patients who have developed CNS B cell CNS lymphoma in the setting of systemic disease as well. Provided there is limited systemic disease, such patients would be eligible
  • Patients fit for autologous stem cell transplantation
  • Patients able to understand and willing to sign a written informed consent document

Exclusion Criteria:

  • Patients with CNS B-cell lymphoma in remission status post primary, initial therapy
  • Patients initially enrolled at relapse but who were not responsive to induction therapy will not be continued on the study
  • Patients whose life expectancy is severely limited by diseases other than malignancy

  • Patients who are pregnant or breastfeeding
  • Patients who are HIV seropositive
  • Patients who have an uncontrolled infection (presumed or documented) with progression after appropriate therapy for greater than one month
  • Patients with symptomatic coronary artery disease, uncontrolled congestive heart failure. Left Ventricular Ejection Fraction is not required to be measured, however if it is measured, patient is excluded if ejection fraction is <30%
  • Patients requiring supplementary continuous oxygen. DLCO is not required to be measured, however if it is measured, patient is excluded if DLCO <35%
  • Patients with clinical or laboratory evidence of liver disease will be evaluated for the cause of liver disease, its clinical severity in terms of liver function and histology, and for the degree of portal hypertension. Patients with any of the following liver function abnormalities will be excluded

    1. Fulminant liver failure
    2. Cirrhosis with evidence of portal hypertension or bridging fibrosis
    3. Alcoholic hepatitis
    4. Esophageal varices

    8. Ascites related to portal hypertension
    9. Chronic viral hepatitis with total serum bilirubin >3 mg/dL ____mg/dL
    10. Symptomatic biliary disease
  • Patients with non-B-cell lymphomas or brain tumors that are not lymphomas are Excluded from the study. Non-B-cell lymphomas include: any T-cell lymphoma, NK-cell lymphomas, and Hodgkin lymphomas
  • Patients for whom an insufficient number of stem cells (<2 X 106/kg) have been collected
