  Purpose
  1. To find the optimal dose of topotecan that can safely be given directly into the spinal fluid (called intrathecal administration) of children whose cancer has spread to the lining of the brain and/or spinal cord.
  2. To find out what effects (good and bad) topotecan has when given directly into the cerebrospinal fluid in children with neoplastic meningitis (cancer that has spread to the lining of the brain and spinal cord).

    • Cerebrospinal fluid is the fluid that circulates around the brain and spinal cord.
  3. To determine if intrathecal topotecan is beneficial to patients.
  4. To better understand how topotecan is handled by the body after intrathecal administration.
  5. To evaluate the cerebrospinal fluid for signs (markers) of tumor spread.

Intervention Details:
    Drug: Topotecan

    Induction (4 weeks): Patients will receive IT topotecan for 5 consecutive days during weeks 1 and 3.

    The Induction period is the first 4 weeks of therapy.

    Drug: Topotecan
    Consolidation (6 weeks): Patients will receive IT topotecan for 5 consecutive days during weeks 1 and 4. The Consolidation period is 6 weeks in duration. Consolidation begins immediately after completion of the 4th week of Induction.
    Drug: Topotecan
    Maintenance (4 weeks for 11 courses): Patients will receive IT topotecan for 5 consecutive days during week 1. Each course of Maintenance is 4 weeks in duration. Maintenance begins immediately after completion of the 6th week of Consolidation.
Detailed Description:

This is a multi-center, non-randomized pharmacokinetically-guided optimal dosing study of intraventricular topotecan in children with neoplastic meningitis. Topotecan will be administered daily for five consecutive days utilizing the schema shown in the Schema below. Concomitant chemotherapy to control systemic disease or bulk CNS disease is allowable provided that the systemic chemotherapy is not an investigational agent or one of the following: high-dose methotrexate (> 1g/m2), high-dose cytarabine (> 1g/m2), 5-fluorouracil, capecitabine, thiotepa, a nitrosourea, or topotecan. The starting dose for this trial was derived from pharmacokinetic simulations that utilized data from a prior phase I study of intrathecal topotecan. The simulations were performed to estimate the length of time that ventricular CSF concentrations of topotecan lactone would remain above an optimal "target level" of 1 ng/mL. One of the primary objectives of this study is to estimate the dose of intrathecal topotecan that will result in CSF lactone concentrations exceeding 1 ng/mL for at least eight hours after an intrathecal injection. Dose escalations for patient cohorts will be conducted following the traditional phase 1 design in order to determine the maximum tolerated dose (MTD). The MTD will be called pharmacokinetically optimal if that dose achieves the targeted PK parameter in at least 23 of 25 patients treated at that dose level.

  Eligibility

Ages Eligible for Study:   3 Years to 21 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Age: Patients must be greater than or equal to 3 years and less than or equal to 21 years of age at study registration.
  2. Diagnosis: Patients must have neoplastic meningitis secondary to an underlying leukemia/lymphoma or a solid tumor (including primary CNS tumors or carcinomas of unknown primary site) for which there is no conventional therapy. Patients with CNS leukemia/lymphoma must be refractory to conventional therapy, including XRT (i.e., 2nd or greater relapse). Neoplastic meningitis is defined as follows: (a)Leukemia/Lymphoma: CSF cell count over 5/µL AND evidence of blast cells on cytospin preparation or by cytology or (b) Solid tumor: Presence of tumor cells on cytospin preparation or cytology OR the unequivocal presence of meningeal disease on MRI scans.
  3. Patients who have leukemia/lymphoma: Patients with CNS leukemia or lymphoma must have a negative bone marrow aspirate assessed within two weeks prior to registration.
  4. Performance Status (Appendix III of full protocol): Karnofsky Performance Scale (KPS for greater than 16 yrs of age) or Lansky Performance Score (LPS for less than or equal to 16 years of age) greater than or equal to 60 assessed within two weeks prior to registration. Patients who are unable to walk because of paralysis, but who are in a wheelchair, will be considered ambulatory for the purposes of the performance score.

    1.2 Leukemia or lymphoma patients: Nuclear medicine CSF flow studies are only required if CSF analysis or an MRI suggests that there may be a blockage to CSF flow. The study must be obtained within 7 days prior to registration. Informed consent must be obtained prior to the CSF flow study.

  2. Underlying illness: Patients with any significant medical illnesses that, in the investigator's opinion, cannot be adequately controlled with appropriate therapy or would compromise a patient's ability to tolerate this therapy.
  3. Concomitant Therapy Patients receiving other therapy (either intrathecal or systemic) designed to treat their leptomeningeal disease are not eligible for this study. Note: Patients receiving concomitant chemotherapy to control systemic disease or bulk CNS disease will be eligible, provided that the systemic chemotherapy is not an investigational agent or one of the following: high-dose methotrexate (> 1g/m2), high-dose cytarabine (> 1g/m2), 5-fluorouracil, capecitabine, thiotepa, a nitrosourea, or topotecan. Please discuss plans for systemic therapy with the Study Chair prior to study entry.
