A Safety Study of Rituximab Plus MTX Injected Into the Cerebrospinal Fluid in the Treatment of Brain Lymphoma

Completed · Phase 1

Conditions studied: Central Nervous System Lymphoma, Intraocular Lymphoma

In brief

Rituximab is the first monoclonal antibody to receive approval in the treatment of cancer and has been proven to lead to extended survival when administered intravenously in the treatment of patients with systemic non-Hodgkin's lymphoma. We have previously demonstrated that a small fraction of Rituximab administered intravenously is able to cross the blood-brain-barrier into the brain. We will test the idea that the direct injection into the cerebrospinal fluid of Rituximab, a monoclonal antibody which attacks and kills lymphoma cells, is safe and when used in combination with methotrexate in patients with recurrent brain and intraocular lymphoma. We will also test the idea that the combination of rituximab plus methotrexate has activity and is effective in the treatment of recurrent brain and intraocular lymphoma.

You may qualify if…

• Relapsed, refractory CNS lymphoma, ocular lymphoma, lymphomatous meningitis
• Tumors must be CD20 + on pathologic analysis.
• Patients must have an Ommaya reservoir (ventricular access device.
• Patients may have had prior intrathecal methotrexate, ara-C or thiotepa but must have recovered from any reversible toxicity caused by prior treatment.
• Concurrent systemic chemotherapy is allowed for treatment of disease outside the meninges with the exception of high-dose methotrexate (>500 mg/m2/d, high-dose ara-C (> 2 gm/m2/d), high-dose thiotepa (>300 mg/m2/d) or investigational agents.
• Patients must have sufficient baseline hematologic function: >1,500 granulocytes and >50,000 platelets/ul.
• Patients must have had a nuclear medicine CSF flow study performed within 30 days of treatment which shows no significant obstruction within the ventricles.

You may not qualify if…

• History of whole brain or craniospinal irradiation or intrathecal chemotherapy < 4 days before initiation of intra-CSF administration of rituximab.
• Anticipated survival of less than one month.
• HIV infection. -
