Summary

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.

Conditions

  • Central Nervous System Lymphoma
  • Intraocular Lymphoma

Interventions

DRUG

Intraventricular Rituximab Plus MTX

Intraventricular injection of rituximab into an Ommaya reservoir on day 1 of each week. Intraventricular rituximab plus methotrexate (MTX) on day 4 of each week. First three patients at dose A : 25 mg rituximab on day 1, and MTX (12 mg) plus rituximab (10 mg) on day 4 each week. If there are no dose limiting toxicities at Dose A in all of the first 3 patients or in 5 of the first 6 patients, the next 3 patients will receive dose level B: 25 mg rituximab on day 1, and combination MTX (12 mg) plus rituximab (25 mg) on day 4 of each week. Oral leucovorin rescue 24 hours after each MTX administration. Maximum injections will be 16 over 9-weeks. Subjects who experience a partial response at week 10 will be given the option for extended dosing.
