About this study
This study is being conducted to evaluate the safety and efficacy of the combination of pemetrexed and zanubrutinib (called induction therapy) followed by zanubrutinib treatment alone (also called maintenance therapy) in people who have relapsed or refractory (RR) primary central nervous system lymphoma (PCNSL) or isolated central nervous system relapse of B cell lymphoma (SCNSL). Assessments include how well people respond to this treatment, whether their disease gets better or worse, and their survival. Safety of this treatment and its side effects also will be assessed.

You may qualify if…
- ✓ 1. Any of the following diseases histologically confirmed:
- ✓ 1. Primary CNS lymphoma or isolated secondary CNS involvement by diffuse large B cell lymphoma with measurable disease
- ✓ 2. Cytologic diagnosis of B cell non-Hodgkin's lymphoma with measurable disease
- ✓ 3. Ocular lymphoma with histologic confirmation of ocular lymphoma and measurable intracranial tumor. Slit-lamp examination and vitreal or retinal biopsy will be done to confirm ocular lymphoma.
- ✓ 2. Karnofsky performance status (KPS) ≥ 30% (≥ 50% for patients ≥ 60 years-old)
- ✓ 3. Progressed during first-line chemotherapy and/or radiotherapy -OR- insufficient clinical response to previous therapy or relapsed after initial successful treatment OR unable to tolerate previous therapy defined as Grade 3+ acute kidney injury (AKI) and/or transaminase elevation according to CTCAE v 5.0 criteria preventing repeat treatment exposure OR prior glucarpidase use due to high dose methotrexate delayed clearance and/or toxicity OR those who would have been glucarpidase candidates due to delayed methotrexate clearance (plasma methotrexate concentrations greater than 2 standard deviations of the mean methotrexate excretion curve specific for the dose of methotrexate administered or toxic plasma methotrexate concentrations (\>1 micromole per liter) in patients with delayed methotrexate clearance) due to impaired renal function OR unable to receive high dose methotrexate induction on every 2 week +/- 3 days schedule due to deconditioning and/OR need for physical rehabilitation between the high dose methotrexate treatments
- ✓ 4. No systemic lymphoma by positron emission tomography (PET) CT or CT scan of the chest, abdomen, and pelvis with contrast
- ✓ 5. Adequate bone marrow and organ function demonstrated by:
You may not qualify if…
- ✕ 1. Serious uncontrolled concurrent illness or comorbid condition
- ✕ 2. Other active systemic malignancy except for basal cell carcinoma of the skin, cervical carcinoma in situ or very low and low risk prostate cancer under observation. Patients with a remote history (3 years or more) of malignancy are eligible for the protocol in the absence of active disease
- ✕ 3. Concurrent chronic systemic immune therapy, targeted therapy not indicated in this study protocol
- ✕ 4. Unable to comprehend the study requirements or who are not likely to comply with the study protocol
- ✕ 5. Prior participation in chemotherapy, cytotoxic therapy, immunotherapy, radiation therapy or therapeutic protocols within 2 weeks of protocol treatment
- ✕ 6. Pregnant (confirmed by serum or urine β-HCG) or lactating
- ✕ 7. Transaminases \> 3 times above the upper limits of the institutional normal
- ✕ 8. Patients must not have pre-existing immunosuppression, concurrent immunosuppressive treatment with the exception of dexamethasone, or low dose prednisone with a total dose equivalent to 15 mg of prednisone a day or less for chronic conditions. Allogeneic stem cell transplant recipients as well as other organ transplant recipients are excluded. Autologous stem cell transplant recipients will qualify if relapse occurs at one year after the stem cell transplantation. Short course of dexamethasone up to 40 mg orally or intravenously daily with or without taper for CNS lymphoma symptom control is allowed.
