The purposes of this study are to find out whether dextromethorphan can prevent the short or long-term neurologic side effects of methotrexate, and whether dextromethorphan can improve symptoms of short-term neurologic side effects if they do occur.

Further study details as provided by Rutgers, The State University of New Jersey:

Primary Outcome Measures:
  • To determine whether dextromethorphan decreases the subacute toxicities associated with intravenous and intrathecal methotrexate [ Time Frame: 5 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • To determine whether dextromethorphan can alleviate acute or subacute neurotoxicity when it does occur after intravenous or intrathecal methotrexate [ Time Frame: 5 years ] [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: March 2003
Study Completion Date: May 2007
Primary Completion Date: May 2007 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Dextromethorphan
    Patients will receive an inert carrier with or without dextromethorphan. The study drug will be administered at 1.5 mg/kg/dose on a BID schedule. The first dose to be given prior to each scheduled intravenous and/or intrathecal administration of methotrexate and continued for a total of seven days.
Detailed Description:
We believe that we are beginning to understand the biological cause of the neurotoxicity that happens after treatment with methotrexate. Dextromethorphan, an ingredient in common cough medicines, may be able to prevent and/or treat this neurotoxicity. We have given dextromethorphan to a small group of patients who developed severe neurologic side effects after methotrexate. All had a complete recovery within one day.

Ages Eligible for Study:   2 Years to 21 Years
