NCT00293475

Brief Summary

This phase I/II trial studies the side effects of methotrexate, mannitol, rituximab, and carboplatin and to see how well they work in treating patients with primary central nervous system lymphoma. Drugs used in chemotherapy, such as methotrexate and carboplatin, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Osmotic blood-brain barrier disruption uses mannitol to open the blood vessels around the brain and allow cancer-killing substances to be carried directly to the brain. Monoclonal antibodies, such as rituximab, may block cancer growth in different ways by targeting certain cells. Giving methotrexate, mannitol, rituximab, and carboplatin together may be an effective treatment for primary central nervous system lymphoma.

Outcome Measures

Primary Outcomes (2)

  • Incidence of toxicities, assessed using National Cancer Institute Common Toxicity Criteria for Adverse Events version 3.0 (Phase I)

    Within 2 months of completion of study treatment

  • CR rate (Phase II)

    Within the first 3 months of treatment

Secondary Outcomes (2)

  • Overall survival

    From entry onto study until death from any cause, assessed at 2 years

  • Event-free survival

    From entry onto study until death or progression of disease, assessed at 2 years

Study Arms (1)

Treatment (rituximab, mannitol, methotrexate, carboplatin)

EXPERIMENTAL

Patients receive rituximab IV over 5 hours on day 1, mannitol IA, methotrexate IA over 10 minutes, and carboplatin IA over 10 minutes on days 2 and 3. Patients then receive sodium thiosulfate IV over 15 minutes at 4 and 8 hours after carboplatin. Treatment repeats monthly for up to 12 courses in the absence of disease progression or unacceptable toxicity.
