Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 3 to 21 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Who may be able to join

  • Age: Patients must be greater than or equal to 3 years and less than or equal to 21 years of age at study registration.
  • 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.

  • 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.
  • Recovery from Prior Therapy: Patients must have recovered from the acute neurotoxic effects of all prior chemotherapy, biological therapy, immunotherapy, or radiotherapy prior to entering this study and must be without uncontrolled significant systemic illness
  • 5.1 Chemo:

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.

About this study

Official title: A Phase I Pharmacokinetic Optimal Dosing Study of Intrathecal Topotecan for Children With Neoplastic Meningitis

  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.
  1. To determine if intrathecal topotecan is beneficial to patients.
  2. To better understand how topotecan is handled by the body after intrathecal administration.
  3. To evaluate the cerebrospinal fluid for signs (markers) of tumor spread.
Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TopotecanDrug

    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.

  • TopotecanDrug

    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.

  • TopotecanDrug

    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.

  2. To describe the toxicities and define the dose-limiting toxicity of intrathecally administered topotecan following intraventricular administration daily for 5 consecutive days.

    Measured: 30 days

  3. To determine if the MTD of intrathecal topotecan is also a pharmacokinetic optimal dose as defined by topotecan lactone concentrations in the cerebral CSF.

    Measured: 7 days

Secondary outcomes (4)
  1. To provide preliminary descriptions of the anti-tumor activity of intraventricular topotecan observed in the heterogeneous diseases that will be treated in this trial.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Topotecan in people with Neoplastic Meningitis, run by Baylor College of Medicine at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 18 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 May 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

To estimate the MTD of intrathecal topotecan administered daily for 5 consecutive days. (time frame: 14 days). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00674674, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 May 2012.
