A Pilot Study of Glucarpidase in Patients with Central Nervous System Lymphoma


Full Title

A Pilot Study of Glucarpidase in Patients with Central Nervous System Lymphoma


The purpose of this study is to evaluate the effects of a drug called glucarpidase when routinely given in combination with methotrexate and rituximab, the standard treatment for central nervous system lymphoma (CNSL). Although methotrexate is very important for treating CNSL, it can sometimes cause serious side effects when methotrexate levels in the blood remain high for a long time. Glucarpidase has been approved by the FDA to treat people who have experienced serious side effects due to high levels of methotrexate.

The researchers of this study hope to demonstrate that lower doses of glucarpidase can be given in patients routinely to reduce levels of methotrexate after treatment and to prevent side effects. This may result in shorter hospital stays. Researchers also want to see if methotrexate plus glucarpidase can be provided on an outpatient basis.

Glucarpidase has already been studied in combination with rituximab and methotrexate and has been demonstrated to be safe. However, the most effective dose of glucarpidase (when given in combination with rituximab and methotrexate) is not yet known.

All three medications in this study are given intravenously (by vein) over several days.

Who Can Join

To be eligible for this study, patients must meet several criteria, including but not limited to the following:

  • Patients must have primary or secondary CNSL, either newly diagnosed or recurrent.
  • Patients must recover from the serious side effects of prior therapies before entering the study.
  • This study is for patients age 18 and older.
